Abstract: 29,541. Byron, A. H., and Smyrk, A. R. Dec. 24, 1912, [Convention date]. Void. [Published under Section 91 of the Act.] Thrashing - machines; hulling, husking, and decorticating.-A harvesting - machine comprises means for cutting the crop, thrashing, dressing, bagging and delivering the grain, and binding and delivering the straw. The machine is mounted on a main wheel 3, aside wheel 4, and a front wheel 6, and is provided with steering-gear 8, a seat 9, and draught appliances 7, or a motor 10. The cut crop is carried by horizontal and inclined conveyers 13, 15 to an endless travelling feed-table or conveyer 16, which delivers it into the main drum casing 17. The blades of the thrashing-drum may be parallel or inclined to the spindle. From the drum, the straw and grain pass through a throat 28 to the shakers, from which the straw is delivered to binding-apparatus, which discharges it on to the ground. The shakers are mounted in a frame 29 provided with a cover 42. They consist of a series of eccentrically-mounted spiked or other rollers 35 having cranked spindles connected together by a bar. The rollers 35 are rotated by means of a pulley 120 on one of their spindles 34, or are shaken by driving the connecting-bar. Between the rollers 35 are plates provided with prongs 44. The plates are shaken by the engagement of clips with eccentrics on the roller spindles. The grain passes through the cavings riddle 47 to an inclined plate 48 which delivers it into a casing 49 containing riddles 58. The riddle 47 and casing 49 are mounted on friction rollers and are reciprocated by eccentrics on shafts 51 and 123, respectively, the travel being limited by stops. A fan 95 delivers an air blast into the casing 49. An elevator 61 carries the grain from the riddles to hummellers or awners consisting of a rotary drum 63 provided with spikes which pass between prongs 67 projecting inwardly from a frame. The drum 63 is driven by a belt or chain from the spindle 27 of the thrashing-drum. The grain passes from the hummellers to riddles 68 reciprocated by an eccentric 70. It is subjected to an air blast from a fan 71 and is carried by a worm 75 into a rotary or other separator 77. The fan and worm are driven by a belt 81 from the spindle 72 of the main fan. The separator 77 consists of a cylindrical sieve divided into four parts having different meshes for separating weed seeds &c. The materials from each part pass through separate hoppers into separate bags placed on a platform 89. After being filled and tied, the bags of grain are dropped down an inclined shoot 90 on to the ground. The mechanism is driven from the motor shaft 101, and from a shaft 100 driven from the main wheel 3 by spur gearing. The motor shaft 101 is connected with the main wheel 3 by driving- chains 107, 108 and a countershaft 106. The shaft 100 is connected by bevel-gearing with a shaft 110 from which the shafts of the thrashing- apparatus are driven by the belt gearing shown. The conveyer 15 is driven by a belt from the shaft 100 and drives the conveyer 13 by a chain. The feed-conveyer 16 is driven from the drum shaft 27 by a belt 130.
