159,962	Feb. 16, 1875	Lubricator for Steam Engines	James Powell	Cincinnati, OH	Abstract: This is an improvement in the class of engine-lubricators known as being automatic in action, in which a delivery-tube is placed within the cup or cistern, so as to receive the oil or other lubricant at the top of the cistern, the oil being supported at the proper level by the waters of condensation formed from the steam within the cistern. In oil-cups of this class a serious~ difficulty has been to render the automatic regulating-valve positive and reliable in its action and the principal cause of this difficulty has been the liability of ordinary valves to stick to their seats, or the passages to become obstructed from various causes, so as to render the steam-pressure on the exposed surface of the valve inadequate to lift the latter. It has also been customary to construct such lubricators with a cap screwing into the neck of the cup to prevent any escape of steam while in use without any means for supporting such caps while unscrewed for the purpose of refilling the cistern. Claim: The combination of the discharge-tube e, constructed with a countersunk or flaring upper end, forming the valve-seat at its outer edge, and the regulating-valve F, forming a sleeve, and constructed with lateral perforations at its upper end for the admission of steam to the cistern, and for the escape of the lubricant as floated up by the water of condensation.
189,651	Apr. 17, 1877	Lubricators for Steam Engines	James Powell	Cincinnati, OH	Abstract: This invention relates to that class of devices which are employed for automatically admitting oil, tallow, or other lubricants to the valve chests of steam-engines, locomotives, &c.; and the first part of my improvements comprises a novel feature, which I have designated the vacuum-chamber, inasmuch as said chamber discharges oil only when steam is shut off:, and when the action of the piston produces a vacuum or partial vacuum in the cylinder of the engine. This vacuum-chamber may he a separate and distinct member with reference to the condensing-chamber, which latter lubricates the engine when steam is turned on; or said vacuum-chamber may be cast in one piece with the condensing-chamber, and be separated therefrom by any suitable partition or division; but in either case the vacuum-chamber is to be arranged so as to discharge its contents gradually and automatically through suitable passages or ports at or near its lower end, which ports communicate through the base and stem of the lubricator with the valve-chest. This discharge from the vacuum-chamber is controlled by a downwardly-opening valve applied to the lower end of a tube or pipe that projects vertically from the bottom- of said chamber, said valve being rendered capable of adjustment in any suitable manner, so as to regulate the flow of lubricant with the utmost nicety. This vacuum-chamber is filled by disengaging from the top of the same a suitable cap, and after the chamber has been charged, said cap is screwed down, thereby hermetically closing the vessel. Claim: An improved steam-engine lubricator, consisting of a condensing -chamber and a vacuum-chamber contained within a single shell, which latter is applied to a stand or base, through which base the contents of said chambers are discharged into the steam-chest.
248,609	Oct. 24, 1881	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to those lubricators whose reservoirs are surmounted with a cup or bell-shaped receptacle, from which receptacle xo he oil or other lubricant flows into the reservoir as soon as the screw-plug is elevated by rotating a handwheel or crank located above said oil-receptacle. The first part of my improvements comprises novel construction of the lubricator, whereby, is the screw-ping is elevated from its seat to charge the reservoir with oil, the accumulated gases and steam are deflected against the sides and inwardly-projecting rim of the cup, instead of being thrown out violently on the person of the engineer. The second part of my improvements comprises a novel combination of devices, whereby I am enabled to dispense with channels or grooves or other oil-passages in the operating-stem of the screw-plug. The oilcup has a depending neck projecting into the reservoir, the lower portion of said neck being provided with a female thread, wherewith is engaged the male screw of the plug-stein, whose upper or exposed end carries a handwheel or other convenient rotating device. Situated between the screw and handwheel of this stem is a conical plug adapted to close against a suitable seat in the cup or neck when the supply of oil is shut off, but as soon as it is desired to charge the reservoir said plug is elevated from its seat, and the lubricant then flows through lateral ports in the neck and fills said reservoir. Claim: An improved lubricator consisting of the oilcup B', having an internal depending neck, C c, paired with one or more ports, Dl, and pro-vided with a slot, b, to receive the lug G, said plug being situated between the operating-screw E and the upper end of plug-stem F.
326,517	Sep. 15, 1885	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to those lubricators or oil-cups, which consist, essentially, of a reservoir or fount having a pair of heads that are clamped against the opposite ends of the fount by means of an axial tube; and the first part of my improvement consists in providing the lower end of the tube with a channel or other outlet that permits the discharge of oil, the flow of the same being regulated by an adjustable rod, ping, or stem traversing said axial tube. I prefer to regulate this discharge of oil by means of a conical valve at the lower end of the stem, which valve is readily adjusted with reference to a suitable seat, the latter being located at the bottom of the axial tube, although the same result can be obtained by means of a channeled rod, or ported plug operating in conjunction with openings in the side of said tube. Claim: The combination, in a lubricator, of a bodily-detachable tube that is screwed into the lower head and has a bearing upon the upper head of the oilcup or reservoir, said tube being provided near its lower end with with one or more inlets, a discharge-channel and a seat for the valve that regulates the flow of oil, which valve is carried by a rod or stem traversing said tube.
326,518	Sep. 15, 1885	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to those lubricators or oilers which have glass founts, globes, or reservoirs that contain the lubricating-fluid and the first part of my improvement consists in imparting a special shape to such reservoirs. This special shape includes a globular or spheroidal fount, a neck which is preferably cylindrical and a contracted waist, the latter being located at the junction of said fount and neck. The fount has an opening at top which is covered by a head or cap of the axial tube that contains the valve and its seat, said tube being screwed into a lower section or cage that fits within the cylindrical portion or sight-chamber of said fount, the upper end of said cage having a bearing that retains a gasket or packing-ring within the contracted waist. By this arrangement, the axial tube serves to clamp all the members of the device securely in place and prevents leakage at the various joints of the same. Claim: As a new article of manufacture, a transparent oil-reservoir consisting of a vessel A, open at top and bottom, and joined by a contraction or annular bearing C to the sight-chamber D said members A, C, and D being composed of a single piece of material, and the contraction C being of less diameter than said vessel A and sight-chamber D.
326,519	Sep. 15, 1885	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to those lubricators io or oilers that employ two separate and distinct chambers, the tipper one of which contains the lubricant, while the lower one serves as a sight-chamber that renders the feed visible, and the first part of my improvement comprises a novel construction of the device whereby the sight-chamber can be readily kept clean and transparent, which result is accomplished as follows: The sight-chamber is located between the lower and intermediate heads of the lubricator, and the metallic member or cage that clamps these two heads together is situated within said chamber, thereby affording a smooth and unobstructed exterior of the latter that prevents the accumulation of dust and grease thereon and renders it an easy matter to clean the same. Claim: The combination, in a lubricator, of the collared tube C c, perforated head B b', and 3a swinging spring-scutcheon D, said scutcheon having a stump or projection, d', and an eye, d, which eye surrounds the collar c.
326,521	Sep. 15, 1885	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to those lubricators, which employ an axial rod, stem, or plug for operating the valve or cutoff that regulates the discharge of oil and my improvement consists in utilizing the upper or outer end of the valve stem as a guide for a reciprocating stopper, which latter, when depressed, permits the cup or reservoir to be filled. Said stopper plays within a slotted or perforated cage or cylinder, and is maintained in its elevated or closed position by a spring that is preferably located within said cage and coiled around the valve-stem, the ascent of the stopper being arrested by the thumbpiece or other lateral projection of said stem. Furthermore, this cage and a spindle thereof act as a tie or hinder that unites the two heads of the cup, and said spindle or prolongation is usually provided with a valve seat, discharge-channel, and one or more ports that allow the oil to flow into said channel when the valve is opened. Claim: The combination, in an oil-cup, of a continuous or uninterrupted rod or stem for controlling the discharge of lubricant with a spring- actuated stopper adapted to reciprocate along the upper portion of said stem and uncover one or more inlets, and an inclosing cage or cylinder, the lower portion of said stern being screwed into a suitable bearing, and its upper end being passed completely through said stopper, thereby serving as a rigid guide for the latter, and permitting the stem to be removed without detaching the stopper.
326,520	Sep. 15, 1885	Lubricator	James Powell	Cincinnati, OH	Abstract: This invention relates to those devices which employ a spring-actuated piston for the purpose of insuring a forced feed of grease or other dense lubricant from a cup, cylinder, or similar reservoir; and the first part of my improvements consists in making the rod of such pistons tubular, and fitting therein a plug or stem whose inner end acts as a cutoff that regulates or entirely stops the flow of grease, as occasion may require. The second part of my improvements consists in providing a lubricator with a pair of clutch-nuts, which are capable of engagement when it is desired to retract and lock the spring-piston preparatory to filling the cup or cylinder. Claim: The combination, in a grease-cup, of a spring-actuated piston for ejecting the lubricant and a cutoff for regulating the escape of the same, said cutoff being located within the tubular rod that carries said piston.
332,623	Dec. 15, 1885	Lubricator	James Powell	Cincinnati, OH	Abstract: The object of my present invention is to simplify the construction, and thereby diminish the cost of manufacturing, those devices which employ a spring-actuated plunger for effecting a discharge of "grease" or other turgid lubricant from a suitable cup, fount, or reservoir. Claim: The combination, in a grease-cup, of a fount or reservoir having a ventage, a spring-actuated piston for effecting a forced feed of the turgid lubricant, a cutoff for regulating the discharge of the same, and a hood or cover which is screwed to said fount and imparts the tension to said spring.
335,146	Feb. 02, 1886	Lubricator	James Powell	Cincinnati, OH	Abstract: This invention relates to those devices which rc employ a spring-actuated piston for inducing a forced feed of that kind of turgid lubricant known as "grease", in contradistinction from oil or other similar fluids which are automatically discharged by simple gravitation and the first part of my improvements comprises a novel combination of piston, piston- rod, spring, hollow screw-threaded adjusting- stem, and an external nut that engages with said stem, the details of said combination. Claim: An improved grease-cup, consisting of a cylindrical fount provided with a discharge-passage and traversed by a piston whose rod passes freely through a tube, which latter is screw-threaded externally to engage with the cap of said fount, a spring being interposed between said piston and the externally-threaded tube, in combination with a cutoff located transversely of said passage in the base of said fount for the purpose of enlarging or contracting the area of the same, and thereby controlling the speed of said piston.
RE10,728	May. 18, 1886	Lubricator	James Powell	Cincinnati, OH	Abstract: The object of my present invention is to simplify the construction, and thereby diminish the cost of manufacturing, those devices which employ a spring-actuated plunger for effecting a discharge of "grease" or other turgid lubricant from a suitable cup, fount, or reservoir. Claim: The combination, in a grease-cup, of a fount or reservoir having a ventage, a spring-actuated piston for effecting a forced feed of the turgid lubricant, a cutoff for regulating the discharge of the same, and a hood or cover which is screwed to said fount and imparts the tension to said spring.
365,629	Jun. 28, 1887	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to those devices commonly known as "sight-feed lubricators" and the first part of my improvements comprises a novel combination of appliances for securing the sight-feed tube between the bottom of the oil-reservoir and the base upon which the latter is mounted. The aforesaid combination includes a windowed bushing, an annular flange, a cylindrical chamber, a sight-feed tube, and a set of counterbores. Claim: A sight-feed lubricator consisting of the reservoir A, having at bottom a discharge-nipple, O, annular counterbores P R, and chamber a , in combination with a detachable base, Wi', provided with an annular counter-bore, U, discharge-channel V, annular flange w, and suitable retaining devices, as X X', a transparent tube, Q, being confined within said counterbores P U, and( a bushing, T, having one or more openings, t, being clamped between said counterbore R and the upper end of said annular flange w.
372,764	Nov. 08, 1887	Lubricator	James W. Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to those lubricators io which are constructed in such a manner as to compel the "feed" or discharging oil to ascend in small globules through a column of condensed water that collects in what is commonly known as the "sight- chamber"' and the first part of my improvements consists in adapting a tubular standard of the device to serve both as the pipe that conveys steam to the condenser and to act as the channel through which oil escapes from the top of the sight- chamber and is then conducted to the engine, said hollow standard being wholly external with reference to the sight-feed chamber and oil-reservoir. Claim: A steam-engine lubricator having an elevated condenser connected by an inlet-passage with an oil-reservoir, which latter has near its top an oil-discharge duct communicating with the bottom of an ascending sight-feed chamber, the upper end of said chamber being provided with an outlet leading into a hollow standard and communicating with a condensing-tube, said standard being wholly external with reference to said oil-reservoir and sight-chamber, and serving the twofold purpose of admitting steam to said condenser and condensing-tube and of receiving the oil that flows from said reservoir.
379,243	Mar. 13, 1888	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: The first part of my improvements consists in locating an enlarged distributing-chamber in the base of the fount, but separate from the latter, the object of this chamber being to prevent an accumulation of oil and water within the "sight-tube", as hereinafter more fully described. The second part of my invention consists in providing the upper portion of the reservoir with a depending flange that serves as a trap or barrier to prevent "condensed water or steam entering the lateral channel leading to the sight-tube. Claim: The combination, in a lubricator, of the reservoir A, having at its base an enlarged distributing-chamber, P, of practically the same diameter as said reservoir, the steam-inlet R, entering the center of said chamber, and a side passage, F, leading from the latter to the bottom of the sight-feed tube.
403,695	May. 21, 1889	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: The first part, of may present improvements comprises a novel combination of standard, oil-reservoir, supporting-arms, channels, and ascending sight-feed tube, whereby a cheap and reliable lubricator is produced, the details of these devices. The second part of my improvements comprises a specific combination of devices for forming a "trap" in the channel or tube that conducts water from an elevated condenser through a lateral arm to the oil-reservoir of a lubricator, the object of this trap being to prevent oil ascending said channel, tube, or passage. Claim: A lubricator having a supporting-standard provided at bottom with a pair of lateral arms and at top with a condenser and a single lateral arm traversed by a duct communicating with the sight-feed chamber, steam-pipe, and main channel in the manner de-scribed, while the lever-arms are traversed by a channel extending from the top of reservoir to the bottom of said chamber, said reservoir being pendent from the arm, and being supplied with water by a channel or pipe leading up to the condenser.
408,927	Aug. 13, 1889	Lubricator	James Powell	Cincinnati, OH	Abstract: This invention relates to those gravity-feed lubricators which are employed for automatically oiling journals and other similar bearings; and the first part of my improvements comprises a novel construction of loosely coupled valve for regulating the discharge from the fount or reservoir, the details of said coupling. Claim: The combination, in a lubricator, of a self-closing valve-carrier, a valve proper flexibly coupled to said carrier, and a reservoir having a seat for said valve to close against, which seat has a discharge-passage.
463,320	Nov. 17, 1891	Lubricator	James Powell	Avondale, Hamillton County, OH	This patent was improved by patent #534,006. Abstract: This invention relates to those up feed-lubricators, which are used on duplicate engine- cylinders or the twin cylinders of a locomotive, are attached to steam-boilers or live- steam pipes, and have a pair of oil-discharge pipes that deliver oil into the steam-cylinders and the principal feature of my present improvements comprises a novel combination of parts that prevents cross-feeding of oil from one cylinder of the engine to the other, and also removes all danger of siphonage when the locomotive runs on a downgrade with steam shut off from either one or both of the cylinders. Claim: The combination, in an up feed-lubricator, of a single oil-fount A, a pair of independent condensers C C', applied thereto and having steam-inlets d cd, steam-tubes c' c', fitted within these condensers and communicating with passages e" e", leading to the dis-charge-pipes E E', a water-channel b, leading from said condensers to said fount, a pair of sight-chambers HI II', provided with nipples h' h', independent feed-tubes 1v' 1c' for supplying oil to said nipples, channels i i, that permit oil to escape from said sight-chambers and flow into said passages e" e", and readily-detachable ejector-nozzles G G, fitted within the latter, said nozzles being pierced with small bores g g.
534,006	Feb. 12, 1895	Lubricator	James Powell	Avondale, Hamilton County, OH	Abstract: The object of this invention is to improve the construction, diminish the cost of manufacture, and increase the efficiency and utility of the peculiar form of up-feed sight-lubricator described and claimed in Letters Patent No. 463,320, granted to me November 17, 1891; the first part of my present improvements being confined to an auxiliary condense-water pocket, which supplies water to the sight glass of the device. The second part of my present improvements consists in providing a special shut off between the live-steam pipe of the condenser, and the top of the sight chamber of the lubricator. The third part of my present improvements consists in providing means for insuring, a better discharge of lubricant from the auxiliary oilcup to an engine cylinder. The fourth part of my present improvements consists in a novel and efficient discharge of "condense water" from the condensers into the main oil-chamber, or fount, so as to prevent the contents of said chamber being siphoned out, in certain emergencies. Claim: T1he combination, in a lubricator, of a reservoir A, having a condenser C; an oil-discharge pipe E; a water-channel b, near the top of said reservoir, and leading to said condenser; a nipple I, having a port i, and communicating with said channel b, by a valve-guarded opening b'; a water-discharge tube J, depending from said nipple; and a cup K , carried by said tube; the receiving end of. said cup being above the level of said port.
533,991	Feb. 12, 1895	Straightway Valve	James H. Layman	Cincinnati, Hamilton County, OH	This patent was improved by patent #610,412. Abstract: My invention comprises a novel combination of devices wherewith the disks of a straightway valve can be forced away from each other when closed or thrown wide open. When closed, said disks are forced tightly against their respective seats, so as to completely obstruct the channels or fluid pas- sages, but when opened, said disks then bear against the walls of the valve-chamber proper. Claim: The combination, in a straightway valve, of a shell having a pair of channels; a chamber provided with a pair of guides and two valve-seats; a vibrating lever whose free end swings within said chamber and has an integral longitudinal-wedge, with its thin end presented toward the axis of said lever; a carrier, perforated on its opposite sides, and adapted to slide freely along said lever; and a pair of valves having pivots inserted within said perforations; the arrangement of these devices being such as to confine said valves to a recti-lineal path within said guide, when the free end of said lever describes an arc of a circle, and to gradually force said valves away from each other as the lever approaches the terminations of its stroke, at which time the thicker portion of said wedge bears against said pivots.
604,265	May. 17, 1898	Lubricator	James Powell	Avondale, Hamilton County, OH	Abstract: This invention relates to and is an improvement on the peculiar form of up-feed sight-lubricator seen in Letters Patent No. 463,320, granted to me November 17, 1891, and also represented in Letters Patent No. 534,006, issued to me February 12, 1895, and the first part of the present case includes a novel arrangement of pipes, channels, &c., which effectually insures a current of live steam in a 0o downward direction to act as an equalizing-supply that drives the lubricant through the oil-discharge pipe to the cylinder or steam- chest or other part to be greased, while at the same time means are secured not only for supplying steam in an upward direction to the condenser for the purpose of condensation, but to prevent undue flooding of said oil-discharge pipe by an overflow of condense water within the live-steam pipe of said condenser. Claim: The combination, in a sight-feed lubricator, of a reservoir; a condenser; a sight-feed chamber; an oil-discharge pipe communicating with said chamber; an external steampipe leading into the base of the condenser; a pipe within the latter, for conveying an upward current of steam; and, near the junction of said steam - pipe and con-denser, a duct that conveys another current of steam down to said oil-discharge pipe.
610,412	Sep. 06, 1898	Straightway Valve	James Powell	Cincinnati, Hamilton County, OH	Abstract: The object of this invention is to improve the construction of the peculiar form of straightway valve seen in Letters Patent No. 533,991, granted to James H. Layman February 12, 1895. In said patent two disk valves are shown having studs or pivots journaled in a longitudinally-slotted carrier traversing the free end of a vibrating lever, which lever terminates with an integral wedge that bears against the ends of said pivots and forces said valves outwardly in the act of opening and closing them; but experience has proven this construction to be deficient in strength on account of the cutting away of the metal near the free end of the lever to form the wedge. I accordingly make this portion of the vibrating lever to enclose the sliding carrier, so as to give greater strength to this part. Furthermore, the wedging device may be integral with the lever or be made separate and inserted within a longitudinal slot of said lever, which slot is traversed by a valve-carrier, and this mode of construction I much prefer. If the wedging or expanding device is made integral with the lever in my improved construction, the box-carrier in that case is preferably divided longitudinally through its center, each half, with its respective circular journal-bearing, being adapted to slide independently of the other half within the slotted sides of the vibrating lever. Claim: The combination, in a straightway valve; of a shell having a pair of channels, a chamber provided with a guide and a valve-seat, a longitudinally-slotted lever whose free end vibrates within said chamber, a slotted slide traversing the lever-slot and having a circular side opening; a detachable expander fitted within said slide and lever, and a valve having a pivot inserted in said side opening, and adapted to be forced outwardly by said expander.
754,547	Mar. 15, 1904	Throttle-Valve	John Desmond	Cincinnati, Hamilton County, OH	Abstract: The leading object of this invention is to so nearly balance this valve by the steam-pressure, as to render its operation and control convenient and delicate, permitting also a quick manipulation, if necessary, and prevent all possibilities which would hinder a free and ready movement and easy lift. Another object is to prevent wear by the eroding and abrasive action of the steam, which cuts the metal when such steam at the time the valve is nearly closed rushes through the contracted space in a thin stream or sheet. Claim: In a throttle-valve, the combination of a valve-housing, a main valve therein, a cylinder open at both ends connected so as to move with this valve and forming with adjacent parts of the valve-housing a movable valve-chamber which is normally closed, an auxiliary valve permitting access of steam to this valve-chamber, a valve-stem to manipulate this auxiliary valve and operative connection between it and the main valve whereby by extended manipulation of the auxiliary valve the main valve is also opened.
776,422	Nov. 29, 1904	Lubricator	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to improvements in lubricators or oil-cups used for supplying lubricant automatically to moving and operating parts in machinery. It relates more particularly to such oilers in which the operation is by gravity and where the discharge may be regulated as to quantity as well as entirely interrupted when desired. Claim: In a lubricator, the combination of an oil-reservoir formed of a cylindrical shell, an upper and a lower head, the latter having a socket on its inner side provided with an outlet-port in its bottom and a drip-nozzle below, a hollow tie-post provided with a shoulder which engages the upper head and by being tapped into the socket of the lower head, holds the heads to each other and in position on the shell to form the oil-reservoir, a spring-actuated valve-stem contained in this tie-post, having a valve at its lower end, a screw-plug to open at both ends to adjust the position of this valve-stem, a cap seated on the upper end of this plug closing the same thereat and engaging it for purposes of rotation to adjust the same, a manipulating handle pivotally attached to the upper end of the valve-stem which latter extends through this plug and cap, protruding beyond this latter and a spring contained under the cap to hold the same normally against the handle in all adjusted positions.
812,362	Feb. 13, 1906	Construction of Oil Cups	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention concerns lubricators or oil-cups used for supplying lubricant to moving and operating parts of machinery, and relates more particularly to devices of the type known as "gravity-feed" cups. They are usually provided with a sight-feed chamber, which permits observation of the feed action, and they have a valve whereby the flow of the oil may be regulated as to the quantity passing and also entirely cut off. A stein is provided for the manipulation of the valve, the operation for the purpose being a rotary one. Claim: In an oil-cup, the combination of an oil-reservoir, consisting of a top, a bottom provided with an outlet-opening and an intervenient shell, a tie-post seated in the bottom and projecting above the top, a nut provided thereat to hold the parts of the cup together, a valve controlling the outlet, a rotary stem for actuating this valve, a pivotally-attached handle to manipulate this stem, a notched locking-arm adjustably mounted on the projecting end of the tie-post and above the nut thereon and adapted to engage the handle to hold the valve-stem against rotation and a o clamping-nut also fitted on the projecting end of the tie-post above the locking-arm to hold the same in its adjusted position.
824,882	Jul. 03, 1906	Grease Cup	James Powell	Cincinnati, Hamilton County, OH	Abstract: The invention relates to improvements in so-called "grease-cups," being a class of lubricators in which the lubricant used is of a viscid consistency, like grease, for instance, and is expelled by a pressure-actuated follower.
RE12,666	Jun. 25, 1907	Grease Cup	James Powell	Cincinnati, Hamilton County, OH	Abstract: The invention relates to improvements in so-called "grease-cups," being a class of lubricators in which the lubricant used is of a viscid consistency, like grease, for instance, and is expelled by a pressure-actuated follower.
882,535	Mar. 17, 1908	Valve Locking Means	James Powell	Cincinnati, Hamilton County, OH	Abstract: This invention relates to means, operating frictionally for locking in adjusted position, valves of such lubricators which feed by gravity and are used for oiling journals and bearings, also for such valves which are used in connection with devices for supplying oil or other fluids to spray nozzles, jets etc. It constitutes an improvement on the device shown in Patent No. 408,927 issued to me on August 13th, 1889. The object of this present invention is to produce a compact, efficient and cheap device for the purpose named, and whereby the rate of discharge of oil may be easily and quickly adjusted and whereby thereafter the regulating parts (valve) may be securely held in adjusted position against accidental disturbance while the lubricator is in use. The invention consists of the particular construction and arrangement of parts as shown and described and whereby the construction is greatly simplified by reducing the number of parts required, to the smallest possible number consistent with efficiency which is accomplished by using existing structural parts of the lubricator for such purpose. Claim: In a lubricator, the combination of an oil-retainer consisting of a shell and a top and bottom, a hollow tie-post seated in the bottom by means of a screw-connection and extending through shell and top and above this latter where it is diametrically increased to form an integral shoulder which, by bearing against the top, serves to hold the parts of the oil-retainer together, there being also vertical serrations on the outside of the tie-post above this shoulder and a valve-seated outlet near its lower end, a carrier adjustably supported within the upper part of the tie-post, a valve for the seat mentioned which has a stem extending upwardly through the lower part of the tie-post, and through and above the carrier in which latter it is supported so as to have a sliding adjustment with reference to the valve-seat, a handle at 11 the upper end of this stem to manipulate the valve for the purpose of opening or closing the outlet and to control passage of oil therethrough and a combined adjusting and locking lever rigidly connected to the upper end of the carrier and shaped to yieldingly engage the serrations in the tie-post and whereby the carrier may be adjusted to regulate the rate of flow through the open outlet and at the same time locked in its adjusted position.
