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 “a new and useful improvement in machines for threshing and cleaning grain.” The specification of Pitts set forth that the inventors “had invented a new and improved combination of machinery for separating grain from the straw and chaff as it proceeds from the threshing machine.” 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 defendant’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 plaintiff’s patent are set forth in the charge of the court."

Pitts v. Whitman
Summary:

“This was a case for the infringement of a patent granted to Hiram A. Pitts and John A. Pitts, as inventors of “a new and useful improvement in the machine for threshing and cleaning grain.” 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 “a new and useful improvement in the machine for threshing and cleaning grain,” and the specification annexed to the letters-patent was in the following terms: “To 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.” The specification then describes the invention, referring to an accompanying drawing. The claim was as follows:
“(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.”

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 —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."

21,495 Sep. 14, 1858 Horse Power Gorges Hely Rochester, Racine County, WI Claim:
The invention here considered has reference to the attaching of the horses to the draft arms of the power, and is designed for equalizing the draft of the several teams.
22,950 Feb. 15, 1859 Horse Power Gorges Hely LaPorte, Laporte County, IN Claim:
The nature of my invention relates to the manner of connecting the draft chains or ropes of a horse power gearing with each other so that each horse or team may be compelled by the action of the other pulling horses to bear its due proportion of the draft, by which means the motion of the machine is not changed by the quick or slow motion of some of the horses. Where the horse power is arranged with four levers, the application of the contrivance is comparatively easy, but where five levers are used as is often the case, it becomes more difficult to use an equalizing arrangement, without making the machine too complicated.

36,611 Oct. 07, 1862 Grain Separator Alexander Gordon Rochester, Monroe County, NY A. B. 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.

910,329 Jan. 19, 1909 Traction Coupling Marquis J. Todd Buffalo, Erie County, NY Abstract:
Heretofore considerable difficulty has been experienced in connecting loaded cars or wagons to each other, as well as in coupling the end wagon of a train to the motor or action engine by which the same is to be transported. If the respective drawbars e out of line when it is desired to effect the coupling it has been usually necessary to employ a chain or some other additional element, as a temporary connection, to cable the train to be started and pulled until the drawbars could be brought into line and thereupon one or more of the vehicles, as for instance the traction engine in reference to the first wagon, had to be backed to effect the direct coupling of the drag-bars.
Claim:
A traction coupler comprising, in combination with a fixed draw-bar, a laterally-movable coupling member, and a laterally-movable member, the latter being pivotally connected to said fixed draw-bar, said coupling member being pivotally mounted on said laterally-movable member.

Claim:
In a road roller, in combination, a main frame, a roll mounted on said frame, continuous racks within the roll at the opposite ends thereof, two sets of gearing at opposite sides of the frame extending into the roll and in mesh with said racks, fixedly mounted shields fitted within the ends of said roll adjacent to said racks, said gearing comprising short shafts, brackets forming bearings for said short shafts mounted on said frame and extending into the roll, beyond the planes of said racks, pinions on said shafts in mesh with said racks, said brackets supporting said shafts on opposite sides of said pinions, and gear wheels on the outer ends of said short shafts, said shields having openings to accommodate said brackets, anal an engine driven shaft mounted on said main frame adjacent to said roll and having pinions in mesh with the gear wheels of said short shafts.
    Road Roller David Farquhar Buffalo, Erie County, NY  
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:

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.
