542	Dec. 29, 1837	Machine for Thrashing and Separating Grain	John A. Pitts	Winthrop, Kennebec County, ME	Litigation involving this patent: Pitts v. Wemple Summary: "This was an action on the case tried by Judge Drummond and a jury, for the infringement of a patent issued to Hiram A. and John A. Pitts, December 29, 1837 [No. 542], and assigned to plaintiff for â€œa new and useful improvement in machines for threshing and cleaning grain.â€ The specification of Pitts set forth that the inventors â€œhad invented a new and improved combination of machinery for separating grain from the straw and chaff as it proceeds from the threshing machine.â€ The chief feature in their invention consisted in an endless belt or apron, proceeding from the threshing machine to the fan-mill, which was of a peculiar construction. The apron was provided with a series of narrow wooden compartments, of a sufficient height above the apron to permit the grain, which was separated. from the straw and chaff by the agitation of the machine when in operation, to fall through into the cells. By this means the straw and chaff were earned along on the tops of the boxes, and kept from being commingled with the grain below, until, by the action of the machine, the compartments were carried forward and emptied the separated grain into the fan-mill, and the straw and chaff passed off over the end of the-apron. Previous to the invention of the plaintiff, an endless apron with cells or buckets, had been used as a carrier, or elevator, to carry flour and other materials from one point to another. The defendant put in evidence a patent issued to Samuel Lane, April 6, 1831. The Lane patent contained an endless apron proceeding from the threshing machine to an endless sieve. The Lane apron had no compartments or cells, but was a smooth apron, and was used in his machine-to carry forward the threshed grain as it came from the thresher, mixed with the-straw and chaff to an endless sieve, by tlie agitation of which sieve the grain was separated from the straw and chaff, which latter were cast off over the end of the sieve, while the sifted grain was conducted from the sieve to the fan-mill. In the defendantâ€™s machine there was also an endless apron, which carried the threshed grain to a peculiarly constructed sieve, secured to Wemple by letters patent, granted July 13, 1844, and the sifted grain was conducted from the-sieve to the fan-mill. It further appeared that the defendant had sometimes used slats about half an inch in thickness, nailed to-the apron, and placed about a foot apart', to give it stiffness and prevent it from sagging at the sides. In addition to these features of the machine, there was what was termed a side elevator in the Pitts machine, which constituted the fourth claim of the patent. This consisted of a larger sieve extending beyond the upper sieve, into which the light grain or tailings which pass over the sieve was received, and from which lower sieve it was conducted through a shoe underneath and a spout to an elevator by which it was taken up and emptied into the upper sieve of the machine, for further sifting. In the Wemple machine there were also a lower projecting sieve and shoe and spout, through which the grain received by them was poured into a side elevator, and was carried forward and emptied into the thresher of the machine. The claims of the plaintiffâ€™s patent are set forth in the charge of the court." Pitts v. Whitman Summary: â€œThis was a case for the infringement of a patent granted to Hiram A. Pitts and John A. Pitts, as inventors of â€œa new and useful improvement in the machine for threshing and cleaning grain.â€ The patent was dated on the 29th of December, A. D. 1837 [No. 542]. The writ was dated on 3d of October, 1840; and the plaintiff in his declaration alleged an assignment by John A. Pitts to himself of all his (John A. Pitts*) right in the invention, for, in, and within the state of Maine; and the breach alleged was, that the defendant [Luther Whitman] after the assignment, unlawfully made, used, and vended the said improvement in the said state of Maine. The cause was tried upon the general issue before the district judge, at the last May term; and a verdict was then taken for the plaintiff. In order to understand the case, it is necessary to state, that the patent was for â€œa new and useful improvement in the machine for threshing and cleaning grain,â€ and the specification annexed to the letters-patent was in the following terms: â€œTo all whom it may concern: Be it known, that we, John A. Pitts and Hiram A. Pitts, of Winthrop, in the county of Kennebec and state of Maine, have invented a new and improved combination of machinery for separating grain from the straw and chaff, as it proceeds from the threshing machine; and we do hereby declare, that the following is a full and exact description thereof.â€ The specification then describes the invention, referring to an accompanying drawing. The claim was as follows: â€œ(1) We claim as our invention the construction and use of an endless apron, divided into troughs or cells, in a machine for cleaning grain, operating substantially in the way described. (2) we claim also the revolving rake for shaking out the straw, and the roller for throwing it off the machine, in combination with such a revolving apron, as set forth. (3) we claim the guard slats, E, in combination with a belt constructed substantially as above described. (4) the combination of the additional sieve and shoe with the elevator for carrying up the light grain in the manner and for the purpose herein set forth.â€ Pitts v. Hall Summary: "This was an action on the case for the infringement of letters patent [No. 542] granted to the plaintiffs [John A. and Hiram A. Pitts] in the year 1837, and extended for seven years, in 1851, under the 18th section of the act of July 4,1836 (0 Stat 124). The declaration alleged that the defendant [Joseph Hall] had, unlawfully and without the consent of the plaintiffs, made, used, and vended to others to be used, large numbers of the machines patented to the plaintiffs, in violation of the exclusive right granted to the plaintiffs by the letters patent and the extension thereof. The defendant pleaded the general issue, and also a special plea, in which he set up that the plaintiff Hiram A. Pitts, after the granting of the letters patent and during their original term, assigned to the plaintiff John A. Pitts, all his- title to the patent and the rights thereby secured, for the states of New York and Michigan; that thereafter, and in the year 1846, John A. Pitts did, by an agreement in writing, transfer to the defendant the one equal undivided half part of all the rights secured by the patent for the states of Michigan and New York; and that it was, by the agreement, agreed by John A. Pitts with the defendant, that in case of the renewal of the patent, or of the obtaining of other or further letters patent for the invention, after the expiration of the existing patent, the defendant should have and be entitled to the equal undivided fourth part of all the rights and benefits that should be secured, by such further or renewed letters patent, for the states of New York and Michigan, on paying to John A. Pitts the proportional one-fourth part of the expenses of obtaining the further or renewed letters patent â€”that is to say, to be proportioned as the value of the right for the states of New York and Michigan should be to that for the other states and territories of the United States; and the defendant to pay the one-fourth part of the proportion for the states of New York and Michigan. The plea also set forth, that the agreement had been duly recorded in the patent office at Washington; that immediately after the extension of the patent, the defendant called upon and saw John A. Pitts, and requested him to inform him, the defendant, what the expenses of obtaining the extension of the patent had been, and stated to him, in substance, that he was ready and willing, and then and there offered, to pay him the proportion of expenses mentioned in the agreement to be paid to John A. Pitts by the defendant; that John A. Pitts then and there declined and refused to inform him what the amount of such expenses had been, although the defendant then was and ever since had been ready and willing to pay John A. Pitts his just proportion of said expenses; that the defendant was wholly ignorant, at the time, of the request and offer to pay, and still was ignorant, of the amount of expenses of obtaining the extension, which ignorance of the defendant was, at said time, well known to John A. Pitts; and that John A. Pitts so declined and refused to make known the amount of such expenses to the defendant, with a view to put it out of the power of the defendant to pay him the just and proper proportion of the expenses, according to the terms of the agreement. To this plea there was a general demurrer and a joinder."

Stoughton - patent attorney In grain thrashing and separating machines a shake-motion has been given to the straw belt or raddle but though this shake motion is valuable in shaking out considerable grain that might otherwise be carried out with the straw and lost, yet it also shakes through straw and other stuff, which get into the fan case and on the sieves, and prevent the free action of the machine. The object of my invention is to retain the advantages of the shake-motion to the raddle and to obviate the disadvantages arising, from it, viz., the clogging of the fan or of the sieves by the straw, which by the ordinary construction of separators also passed through the raddle; and the nature of my invention consists in combining with a straw belt or raddle, having a shake motion, a rack or series of slats placed within the belt or raddle for the purpose of preventing the straw from falling through the belt and thence passing into the machine.

407,806	Jul. 30, 1889	Valve Gear for Engines	Ellis J. Woolf	Minneapolis, Hennepin County, MN	This patent was improved with patent #444,563. Abstract: Our invention relates to that class of radial valve-gear in which the amount of lead or advance, variable cut-off, and expansion and reverse action is sought to he obtained from one eccentric, crank, or radial pin to which an arm is attached, having its outer end pivoted in a guide. The general object of our invention is to obtain the nearest possible approximation to an absolutely perfect valve movement, in other words, to secure an almost absolutely equal alternate pressure behind the piston-head for both in and out strokes throughout the whole range of cutoffs and to deliver to the crankpin an equal rotative force at all corresponding points on both the in and out strokes. Claim: In a valve-gear, the combination, with an eccentric or crank, of a rigid arm actuated by the eccentric or crank, a guide for said arm constraining it to move in a definite path, and a rod for driving the valve attached to said arm at a point offset from the center lire of the arm's motion.

444,563	Jan. 13, 1891	Valve-Gear for Engines	Ellis J. Woolf	Minneapolis, Hennepin County, MN	Abstract: My invention relates to radial valve-gear. It was especially designed for use in connection with the valve-gear described in United States Letters Patent issued jointly to myself and John Peebles, of date July 30, 1889, numbered 407,806, but is capable of use on other forms of radial gear wherein the restraining device for constraining the outer end of the strap to pursue a definite path is mounted on a standard or carrier supported on the eccentric-shaft. The leading feature of the invention has for its object to provide a carrier for the restraining device which will automatically adjust itself to the relative movements of the axle and the frame and which will always present a rigid base of resistance to the valve- thrust. The devices hitherto designed to permit the rising and falling of the axle have never, so far as I am aware, been rigid with reference to the valve-thrust. More or less loose joints have always intervened, impairing the motion and injuring the engine. For example, guide-pins fixed to the frame or boiler have been employed in cooperation with perforated lugs on the head of the standard, as shown in said former patent. Radius-bars have also been used pivotally connected at one end to the upper end of the standard and at the other to the frame. In both cases the necessary play at the joints, namely, between the pin and the lug in the one ease and at the pivots in the other-permits the standard to move with every thrust of the valve, progressively increasing in degree with usage. This imparts a succession of blows to the standard, the restraining device, the strap, and the engine-frame. The frame and all parts supported thereby are kept in a continuous tremble, greatly to the discomfort of the engineer and fireman and increasing the wear and tear on the entire locomotive. Tie lost motion at the joints of the carrier becomes cumulative at the restraining device and strap. The effect on the valve is to delay its movement, increasing with usage, rendering the engine loggy and impairing the distribution of the steam. The necessity for an automatically-adjustable carrier which should be free from the above-noted defects led to this feature of my invention, the efficiency of which for the purpose has been demonstrated by extensive usage. To these ends I construct the carrier in the form of a rigid bell-crank lever, the two arms of which are preferably of unequal length. The short arm or standard proper is loosely mounted on the axle and supports the restraining device, while the long arm is connected at its outer end to some support independent of the axle, preferably some part of the frame, in such a manner as to be permitted a limited to-and-fro motion in the direction of its length upon the rising and falling of the axle, but no motion whatever at an angle to its to-and-fro motion, and hence no motion whatever under the thrust from the valve. The carrier is therefore pivotal with reference to the relative movements of the axle and the frame, but is rigid with reference to the valve-thrust. I have shown two means of effecting the connection between the long arm of the carrier and the fixed support, so as to permit the requisite to-and-fro motion, one being a pair of jaws on the outer end of the arm embracing a crossbar on the frame and the other a pivotal connection with a pivoted hanger on the frame. Both will 9c work well; but the latter is my preferred construction. The long arms of the carrier may be of any suitable construction so long as it is rigid with the short arm or standard. Claim: A carrier for a valve-gear, consisting of a rigid bell-crank lever having one arm loosely mounted on the eccentric-shaft and the other connected to some independent Timo support, with freedom 'for a limited move-meat in tile direction of its length, but without freedom to move at an angle to the line of its to-and-fro motion, whereby, while automatically adjusting the gear to the rising and falling of the shaft, the carrier always presents a rigid base of resistance to the valve-thrust.
455,872	Jul. 14, 1891	Valve Gear for Engines	Ellis J. Woolf	Minneapolis, Hennepin County, MN	Abstract: Our invention relates especially to that class of valve-gears described in the United States Letters Patent issued to us of date July 30, 1889, numbered 407,806, and in the pending application of Ellis J. Woolf, under Serial No. 348,662, filed April 19, 1890, and allowed November 14, 1890. It was designed in order to get the best results on traction and some other forms of engines; but the improvement is also capable of general application to some other forms of valve-gear. It has for its object to provide an additional means of further overcoming the obliquity of the main rod with a view of obtaining a more equal distribution of the steam. This is done by extending the eccentric-rod from the strap in the opposite direction to the main rod from the crank, thus reversing their angularities and obtaining necessary compensation. In order to transfer the motion from the outer end of the eccentric-rod to the valve, a suitable transfer or directing device is provided adapted to support the outer ends of both the eccentric-rod and the valve-rod. This directing or transferring device may be either a straight-line guide or a pivoted rocker. If the eccentric be placed opposite the crank, the connection from the directing or transferring device to the valve must be direct. If, however, the eccentric be placed in line with the crank, the connection must be indirect, which can be readily effected by making the pivoted rocker a reversing-rocker or by making the transferring device in any other suitable form adapted to reverse the motion in its transmittal to the valve. Claim: In a valve-gear, the combination, with the crank and the main rod, of an eccentric, an eccentric-strap, an eccentric-rod extending from the strap in a direction opposite from the main rod, and a directing device for supporting the outer ends of the eccentric-rod and the valve-rod and transferring the motion to the valve.

976,012	Nov. 15, 1910	Road Roller	Marquis J. Todd	Buffalo, Erie County, NY	Abstract: It is well known in the art that in transporting road-rollers, more or less difficulty is experienced by skidding in passing over crowned roadbeds. This is due to the fact that the wide rollers by which the machines are steered have but limited contact with the road, namely, at the center, and this being in vertical line with the pivots of the roller-yokes the machines will rock to one side, and when being steered will usually skid toward the side of the road. It is my purpose to overcome this difficulty by making the front roll in sections so that the central section may be removed with the result that the machine may be used as a traction engine, the two end sections of the front roll serving as carrying wheels. Claim: A road-roller having front and rear carrying wheels, a roll designed to fit between the front carrying wheels and to form with the latter a front roll, and means carried by said roll for detachably securing it in place.
981,499	Jan. 10, 1911	Steering Mechanism for Road Freight Cars	Marquis J. Todd	Buffalo, Erie County, NY	Abstract: n the transportation of heavy freight by a train of road cars or wagons, each carrying between twelve and fifteen tons of freight, it is frequently necessary that the train be moved in reverse order so that a car or cars in or near the normal rear end of the train may be properly positioned to receive or discharge freight. This requires that the steering of the train be accomplished from what is now the forward end of the otherwise rear car. This steering is effected by shifting the carrying wheels. Claim: In a reversible road freight ear or wagon, the combination of a body, a centrally pivoted axle, carrying wheels thereon, a fifth wheel carried by the axle, a bodily detachable lever fulcrumed on the-car body at a point beyond the pivot of the axle, and means for detachably locking said lever to the fifth wheel to enable said axle and carrying wheels to be shifted relatively to the car-body, the point of locking the lever to the fifth wheel being close to the fulcrum of the lever.
