Abstract: 170,934. White, W. E. July 29, 1920. Discharging throw-off and feeding devices for endless-belt conveyers.- A machine for collecting, loading, and transporting sheaves comprises a body portion carrying an adjustable elevator provided with a picking-up device and forming at its rear end a container for the collected sheaves, the supporting wheels of the body being enclosed within the framing. The body has sills 2 connected by cross beams 8, 9 and supporting uprights 5, 6, 7. The lower portion of the side walls is formed by slats 11 and the upper portion by slats 12, the slats 12 being spaced more widely than the slats 11. The main wheels 19, 20, are enclosed in housings 25 which have top decks 26 to increase the volume of the container. The container is closed at the rear by a gate 28 hanging from the top beam. A sweep 30 is adapted to move along the floor of the container and is provided with eyes to which ropes extending through the rear end of the container may be attached for the purpose of hauling the sweep backwards to discharge the accumulated sheaves. Forward movement of the sweep is obtained by turning a crank 44 on a shaft 43 connected by chain gear with a shaft 40 on which are secured drums for cables 38 attached to the sweep. The conveyer frame 44<a>, which is less in width than the distance between the front steering wheels 21, carries at the forward end of each side beam a casting 47 in which a cam-channel 49 is formed. A shaft 51 carrying a rotary picking-up device is mounted in bearings in the plate 47 and is provided with sprocket wheels 54 round which the chains of the conveyer pass. The picking-up device comprises tines 59 secured to shafts 55 rotatably mounted in the sprocket wheels 54 and in a central pulley wheel 56. The shafts 55 are provided at their outer ends with cranks 73 carrying rolls engaging in the cam channels 49, thus causing the ends of the tines to follow the path indicated in Fig. 8 as the picking-up device is rotated. Holes for lubricating are formed in the castings 47. The pulley 56 is provided with a belt 58 extending to a similar belt on the upper shaft of the conveyer. The conveyer is provided with flights 62 carried by offset connectors or side chains 63 and connected to the belt 58. The flights carry fingers 65 mounted resiliently in order to yield when an obstruction is engaged. The working surface of each flight is provided with a metallic cover. The flights travel over a floor 90 between the side frames of the conveyer. The shaft 51 extends through the castings 47 into supports connected by links 81 to one of the cross beams 9 of the machine and these supports are attached by rods 84 to rock arms 83 movable by a lever and quadrant 85 to adjust the height of the front end of the conveyer. The upper end of the conveyer is provided with a belt-tightening device 91. The shaft 51 is connected by a belt to a countershaft 95 adapted to be driven by a friction wheel 98 on a shaft 97 connected by chain-and-sprocket gear to the main wheel 20. The shaft 97 is mounted in rock arms which can be moved by a hand-lever 102 to bring the friction wheel into operation. The upper end of the conveyer has attached to it cables 111 adapted to be wound on drums on a shaft 108. The shaft 108 is rotated by winding up a cable 114 on a drum operated by a hand-wheel 117, the other end of this cable passing round another drum secured to the shaft 108. The lower end of the conveyer is connected to the side frames of the machine by links 118. The front wheels are secured upon vertical steering shafts provided with rock arms connected bv a rod for simultaneous operation.
