Apparatus for Drilling and Operating Oil Wells
|
Joseph Reid |
Oil City, Venango County, PA |
Abstract:
My invention relates to apparatus through the medium of which explosive-engines may be combined with ordinary well-drilling and well operating apparatus in a manner to meet the requirements of handling the tools, materials, and implements incident to constructing oil-wells and the performance of work incident to the operating of such wells. Certain improvements in this class of apparatus are described and claimed in my Letters Patent No. 626,933, granted June 13, 1899, in which was described a well-rig having a constantly-running explosive-engine and means for stopping, starting, and reversing its connection with the rig, all under control of the operator on the derrick-floor.
Steam-engines are very expensive for operating wells, first, because of the cost of the oufit; secondly, because of the expense of fuel and the cost of hauling into the place of use, often difficult of access; thirdly, because of the expense of procuring water for the boilers, and, fourthly, because of difficulty of repeatedly moving the outfit from point to point. An explosive-engine offers superior advantages in all of the above-recited particulars; but explosive-engines were formerly not available for these purposes owing to the impracticability of readily reversing them or accurately varying their speed at will or stopping or starting. My previous patent provided means whereby explosive-engines may be used as the source of power employed for performing all of the various kinds of work incident to deep-well drilling; but the control of the transmission of power was by a separate mechanism located at an intermediate point between the engine and the derrick and having belt connection to each. This particular embodiment of my patented ideas is objectionable in some cases, because of the extra amount of mechanism and belting employed, which entailed original expense, uncertainty of operation, and bulkiness in transportation. The parts of an outfit must be as few as possible and such that they can be readily handled without special means for lifting and may be carried on comparatively small vehicles Without danger of injuring shafting and other parts. Long shafting cannot therefore be used with satisfactory results.
My present invention consists in a novel construction and arrangement of the stopping, starting, and reversing mechanism in combination with the other parts of the well drilling or operating rig set forth in my aforesaid Letters Patent, the above-mentioned mechanism being arranged in alignment with and directly coupled to the main shaft of the explosive engine, so that all intermediate belting is disposed of and so constructed as to make a novel means of connection between the said stopping, starting, and reversing mechanism and render the parts readily separable for easy transportation, the controlling levers extending forward to the derrick-floor in the same manner as described in my aforesaid patent.
Claims:
l. The combination of a well drilling and operating apparatus, a continuously-running explosive-engine having a main drive-shaft, a power-transmitting shaft in alignment with said main drive-shaft, a coupling detachably securing the transmitting-shaft directly to the main shaft end to end, and a stopping, starting and reversing clutch on said transmitting-shaft and suitable means including a brake pulley and band for the direct driving connection and connections from the movable member of the clutch and the brake band.
2. The combination with a well drilling and operating apparatus, of a continuously-running explosive-engine having a main driveshaft, a power-transmitting shaft in alignment with main drive-shaft, having a drive-pulley or drum, a coupling detachably securing the transmitting-shaft directly to the main shaft end to end, a stopping, starting and reversing clutch including a brake wheel and band on said transmitting-shaft, and suitable means to operate the said clutches extending forward to the derrick-floor, consisting of rods extending from the clutch and brake-band to the derrick-floor, and a lever having connections including other levers, through which it controls the operation of the clutch and brake-hand and moves said reversing-gear and clutch simultaneously and throws one into and the other out of driving relation to said pulley or drum.
3. The combination of a Well drilling and operating apparatus, a continuously-running explosive-engine having a main drive-shaft, a power-transmitting shaft in alignment with said main drive-shaft, a coupling detachably securing the transmitting-shaft directly to the main shaft end to end and stopping, starting and reversing clutch on said transmitting-shaft and suitable means to operate the said clutch extending forward to the derrick-floor; said clutch and operating means consisting of a transmitting pulley or drum loose upon said shaft, a reversing-gear on said shaft thrown into and out of driving relation with said pulley or drum, a wheel concentric with said shaft and a brake-band applied to said wheel, a brake-band lever for applying said brake, a friction clutch forced by a movement longitudinally to the shaft into and out of driving relation With the transmitting pulley or drum, a bell-crank lever having one end presented in a direction to impart said longitudinal movement to the clutch, and a rock -shaft parallel with the continuously rotating shaft having oppositely projecting levers connected respectively with the brake-band lever and with the bell-crank lever and thereby adapted to impart movements transversely and longitudinally of the rotating shaft and throw the reversing gear and friction-clutch alternately into and out of driving relation to the transmitting pulley or drum.

Governing Valve for Gas Engines
|
Wilber O. Platt |
Oil City, Venango County, PA |
Abstract:
This invention pertains to internal combustion engines, more particularly to the fuel feeding regulating means therefor, and has for its purpose to further improve on that general type of fuel feeder shown in the patent granted to Joseph Reid, No. 607,276, dated July 12, 1898.
This type of fuel feeder embodies in its structure a supply cylinder adapted to receive charges of air and gas, which charges after commingling are delivered to the explosive chamber of the engine. To properly proportion these charges of air and gas it is necessary that their respective inlet valves vary in dimension corresponding to the proportions of mixture required, and to accomplish which the gas intake valve is of considerably less dimension than the valve of the air intake. To have these valves in proper working condition there must necessarily be some difference between the diameters of the valves proper and the holes in which they operate, and thus when substantially in closed position there must necessarily be slight spaces through which the elements of combustion leak into the mixing chamber by reason of the vacuum created in the pumping or supply cylinder. Owing to the fact that the leakage through the gas valve is not in the same proportion as the leakage of the air valve, as the gas is to the air in the charge, the mixture occasioned by said-leakage is improportionate in that it contains a greater proportionate amount of gas than air, and with the increase in suction there is a corresponding increase in the excess of gas in the mixture. The vacuum produced in the charge forming cylinder has a retarding effect on the engine and there is the further fault of a tendency to back firing. In overcoming these defects this invention embodies the idea of providing means whereby a constant charge, or proportionate excess of air to gas, is admitted to the mixing chamber whereby to neutralize the normal excess of gas above referred to.
Claims:
1. In a fuel feeder controller for explosive engines, the combination with a casing having a mixing chamber, of valves operable within said easing and admitting air and gas to the mixing chamber, said air valve provided with slots in one of its marginal edges, said slots adapted to constantly register with the mixing chamber, and means for proportionately varying the admission openings of said valves.
2. In a fuel feeder controller for explosive engines, the combination with a casing having a mixing chamber, of valves operable within said casing and admitting air and gas to the mixing chamber, said valves arranged in parallel, said air valve provided with slots in one of its marginal edges, said slots adapted to constantly register with the mixing chamber, and means for proportionately varying the admission openings of said valves.
3. In a fuel feeder controller for explosive engines, the combination with a casing having a mixing chamber, of valves adapted to reciprocate within said casing and admit air and gas to the mixing chamber, said valves being of substantially cylindrical tubular structure and disposed in parallel, outlet openings in said valves adapted to register with the mixing chamber, said air valve having slots cut therein immediately adjacent its outlet opening, said slots adapted to constantly register with the mixing chamber whereby air is continuously admitted thereto, and means for proportionately varying the position of said valves.

Lubricating Eccentric Driving Gears
|
John Reid |
Oil City, Venango County, PA |
Abstract:
This invention relates to horizontal eccentric driving gears such as are used in pumping plants, and particularly to a means for providing adequate lubrication for the same while preventing the scattering of lubricating oil.
In the usual construction at the present time there is nothing but a low lip around the periphery of the eccentric to prevent the lubricating oil from being thrown off by centrifugal force from the lower edge of the eccentric after passing down between the bearing surfaces. Any excess oil is thrown toward the portion of this lip furthest removed from the center of rotation and spills over the edge. It is difficult to regulate the supply of oil so that there will be sufficient to properly lubricate the bearing surfaces without having some spilling over the above mentioned lip.
According to the present invention the lip is extended upward to substantially the height of the bearing surfaces, and is preferably curved inward at' the top, thus forming a ring shaped cup of adequate proportions for catching the oil discharging from the lower edges of the bearing surfaces.
Most of the oil is thrown by centrifugal force to that portion of the cup furthest removed from the center of rotation of the eccentric, and forms there a relatively deep pool. In accordance with another feature of the invention I provide a pump having an intake terminating in this deep pool of oil and a delivery tube for supplying oil to the bearing surfaces. I am therefore able to supply the bearing surfaces with a continuous flow of oil and thereby obtain maximum efficiency of lubrication. The pump is conveniently operated by means of a cam surface on the eccentric ring, since the pump is secured to the eccentric and travels around the ring.
Claims:
1. In combination with a horizontal eccentric driving gear comprising an eccentric and an eccentric ring cooperating therewith and having a lip extending outwardly from the bottom of said eccentric and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said lip at the portion thereof-furthest removed from the center of rotation of the eccentric, and a delivery conduit for said pump communicating with the bearing surfaces of the eccentric and eccentric ring.
2. In combination with a horizontal eccentric driving gear, comprising an eccentric and an eccentric ring cooperating therewith, and having a lip extending outwardly from the bottom of said eccentric, and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said lip at the portion thereof furthest removed from the center of rotation, upward extensions on said eccentric and said eccentric ring forming an oil receiving well above their bearing surfaces, and a delivery conduit for said pump communicating with said well.
3. In combination with a horizontal eccentric driving gear comprising an eccentric and an eccentric ring cooperating therewith and having a lip extending outwardly from the bottom of said eccentric and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said ip at the portion thereof furthest removed from the center of rotation, upward extensions on said eccentric and said eccentric ring forming an oil receiving Well above their bearing surfaces, said eccentric also having a recess opening into said well, oil conduits extending from said recess downwardly along the bearing surfaces, and a delivery conduit for said pump opening into said recess.
