Henry W. McAuley, De Soto, Wis.-This invention consists in certain improvements in the form and arrangements of the buckets and in chutes for delivering the water thereto.
James Capen, Charlton, Mass.-This invention relates to improvements in hay loaders, and consists in the application to the rear end of a hay wagon of an endless elevator case and rake, the latter having spring teeth, and arranged for adjustment by means of a hand lever at the front and suitable connecting devices; and the elevator is connected with one or both of the hind wheels of the wagon by machine chains or belts for operation.
Francis Stein and Henry Haering, New York city.-This invention consists in the application to a pair of vertical ports or ways with toothed racks, of a carriage or platform having a shaft provided with a gear wheel at or near each end, and gearing into the toothed rack; also, having in suitable cases sliding on the posts a set of hoisting gears, gearing with the toothed racks and operated by hand cranks, and provided with ratchet wheels, holding pawls, and friction apparatus, arranged in a peculiar way for elevating the platform, holding it in any desired position or governing its descent.
C. Mayer, Sullivan, Ill.-This invention relates to improvements in tables, and consists in arranging the side rails of the top of the frame, which are enlarged at the center and hinged to the posts for folding against the cross rails, when the top, which is detachably connected, is removed, for economy of space and convenience, in packing for transportation or storage; also in arranging the legs for folding up against the under edge of the cross rails; also in an improved arrangement of the side rails for extension.
S. Geo. Knapp, Woodhaven, N.Y.-This invention relates to an improved mode of manufacturing sheet-metal flour, grain, and other scoops, and consists in forming the bowls in one piece of metal, without seams or joints, by stamping up sheets of metal into the form of a trough, with a flange around the top, and cutting the same transversely in the center, with blanks for the bowls of two scoops, to be finished by trimming or shaping the cut ends, turning down the flange at the top, for stiffening either over wire or not and attaching the handle; the object being to produce scoops with bowls formed in one piece, and shaped at the base or in the part where the handles are connected, and to smoothly effect an economy of labor by stamping two blanks at one blow of the drop press, and also to control the metal under the action of the drop better in shaping the deep curved part of the base so as to upset and stiffen the blanks thereat.
