Manufactured by C. H. Bidwell Thresher Co. - Batavia, Genesee County NY

Abstract: The object of my invention is to provide an improved means for the removal from the machine of the fine particles of dirt and small seeds that escape through the usual screen in the lower grain-pan of a threshing-machine, such that such fine particles of dirt and small seeds shall he carried to one end of the machine and delivered there in a pile rather than having such fine particles of dirt and small seeds delivered to a barrel by the usual worm working in a trough. I have found that the use of a barrel for catching this refuse is objectionable, in that it takes up room and the barrels when full have to be removed and replaced by empty ones. Claim: In a threshing-machine, in combination with a grain-pan having a screen therein and a trough and worm beneath such screen, a fan supported at one end of such trough and worm therein, such worm arranged to deliver the contents of such trough to such fan, and means for revolving such fan and delivering the contents emptied therein from such worm to one end of the machine, such fan supported on a sleeve revoluble on the shaft for such worm, such sleeve also carrying a pulley by means of which such fan may be driven.

Assigned to Joseph Reif - Hebron IN

Claim 1: In a wrench, the combination of a pair of members, each provided with a gripping jaw, a handle rigid with one of the members, teeth on the members respectively inter-meshing to force the jaws together by movement of the handle-member relatively to the other member, a frame for holding the members in connected relation, and a pivotal connection between the frame and the handle-member, said connection comprising lugs formed on the sides of the handle-member and slots formed in the frame, said slots having open ends to permit lateral insertion or withdrawal of the lugs. Evolved from earlier patents 883,287 and 899,805. The REIF wrench brought to market more closely resembles this patent than the earlier ones.

Manufactured by C. H. Bidwell Thresher Co. - Batavia, Genesee County NY

Abstract: I have found that the feeding mechanism usually employed in grain-threshing machines does not work satisfactorily in bean-threshers on account of the tendency of the bean-stalks, especially after remaining any length of time in the mow, to string and pass over the feeding mechanism in bunches. Another objection to the feeding mechanisms used in grain-threshing machines consists in the difficulty experienced in attempting to remove stone from the beanstalks just before they enter the cylinder. The present methods of harvesting beans result in quite a quantity of stones being clogged up with the beans, and frequently they get upon the table and over the feeding mechanism into the cylinder, damaging the cylinder and concave. To overcome these difficulties, I have devised a self-feeding mechanism in which the presence of stones of any size sufficient to do serious damage gives an audible signal, and the operator may then readily tip the feeding mechanism in such a way that the stone will pass off from the feeding mechanism onto the ground without entering the cylinder. Claim: In a threshing-machine, a feeding mechanism consisting in a shaking- pan having teeth formed thereon, a handle or lever and connections between such handle and shaking-pan whereby such pan may be swung upward and to the rear on its operating crank-shaft by the movement of such handle, mechanism for operating such crank-shaft and connections between such handle and mechanism whereby the operative connection between such crankshaft and mechanism may 8 be broken by the movement of such handle.

Manufactured by A. D. Baker Co. - Swanton, Fulton County OH

Patented in Canada, #CA-131,928. Abstract: My invention relates to a variable cut-off valve gear for locomotives and traction engines, and has for its object to provide for engines of the classes described a simple, light, durable and efficient valve gear of the kind, that is adapted to adjust the length of valve stroke to vary the extent of port openings and point of cutoff and to operate the valve at alternately quick and slow speeds during its stroke, to effect quick and full opening of the admission port at the beginning of each stroke of the piston to the extent the established valve stroke permits and maintain it so fully open to near the point of cutoff; quick cutoff at equal distances of piston travel on the forward and backward strokes; and quick release at the end of each stroke of the piston, of steam admitted during the stroke, and free continuation of its release during the next succeeding stroke. Claim: In a variable cutoff valve gear for locomotives, the combination with the main frame, eccentric rod, slide valve and cross head, of a support mounted on the frame, a bell crank journaled on the support, a link connecting one arm of the bell crank to the forward end of the eccentric rod, a lever fulcrumed on the other arm of the bell crank, a stem connecting the valve with the lever near its fulcrum, a link connecting the cross head to the lever at a proportionally greater distance, from the fulcrum than the connection of the stem, a member mounted on the support and adjustable thereon through an arc, a rocker pivotally connected at one end to the adjustable member and at the other end to the bell crank link, the radial distance from said first to said second pivotal connection of the rockier being equal to the radial distance of its first pivotal connection from the center of the arc of movement of the adjustable member, and means to adjust and establish the adjustable member at different points in the arc of its movement.
