Abstract

170,131. Fowler, W., and Ewing, M. July 23, 1920. Ratchet and like step-by-step conveyers and elevators.-In hay-loaders comprising rakes which push the hay up a sloping platform, the rakes are mounted on eccentrics on two shafts which are connected by gearing and are driven from the travelling wheels through a countershaft or its equivalent. The wheels 4 are provided with ribs 5 on their treads and drive sprocket-wheels 8 through free-wheel clutches which may be thrown out of operation simultaneously by means of a hand-lever 13. Each sprocket 8 is geared by a chain 14 to a smaller sprocket 15 on a dummy or stub axle. Interchangeable pinions 16, 17 connect the sprockets 15 with a shaft 18 on which are mounted eccentrics 19 arranged at angles of 120‹ with one another. The rake-bars 20 are connected through strips 21 to the eccentrics 19 and to similar eccentrics 26 on a shaft 25 driven from the shaft 18 by chain gearing 22, 23, 24. Roller or other bearings may be provided in connection with the eccentrics, and the shaft 18 may be squared at the end to receive a crank handle for moving the mechanism by hand. The machine is provided with an adjustable discharge platform 27 and draw-bar 30. Castor wheels are adjustably mounted on the rear part of the frame 1 for regulating the position of the lowest spring tines 34 relatively to the ground.
