Claims

Claim.lst. In a thrashing-machine provided with an ordinary drum cylinder, having grooved steel beaters of the usual description, the combination of a concave formed of bars C, with a grate D inserted between each pair of bars, substantially as and for the purpose specified. 2nd. In the concave of a thrashing-machine, the bars C, having tennon ends to fit into the sockets a, made in the curved end castings B, and bolt-holes b, at equal distances apart in the centre of the bar C, in combination with a grate D, inserted between each pair of bars C, and having bolt-holes corresponding with those through the bars C, substantially as and for the purpose, specified. 3rd. In a thrashing-machine, an open-bottom straw-shaker F, supported at an angle extending upwardly from the cylinder to a point above the tail-rake by the slanting spring hangers H, in combination with driving mechanism arranged to impart a longitudinal reciprocating motion to the shakers, substantially as and for the purpose specified. 4th. In a thrashing-machine, an open-bottom straw-shaker F, having a longitudinally reciprocating motion, in combination with an inclined bridge f, formed across the upper surface of the shaker F, substantially as and for the purpose specified. 5th. In a thrashing- machine, a jog tray or grain carrier E, having a close bottom formed as described, and deriving a longitudinally reciprocating motion, as specified, in combination with perforations made through the bottom of the carrier E, immediately over the dressing-shoe K, substantially as and for the purpose specified. 6th. In a thrashing-machine provided with a vibrating grain-carrier and a vibrating shaker, a series of spring hangers H, the bottom end of each being connected to a spool h, having a hole through it to permit the passage of the pivot-pin used in connecting the hanger to the shaker or carrier, in combination with the brackets g, fixed to the frame of the machine and arranged to adjustably hold the spring hangers, substantially as and for the purpose specified, 7th. In a thrashing-machine, a straw-shaker F, located above the grain-carrier R, both being supported from the frame of the machine by the spring hangers H, in combination with the double crank-shaft I, connected by the rods J to the carrier E, and shaker F, in order that the evolving of the crank-shaft impart mpart a longitudinal reciprocating motion to the said shaker and carrier, the cranks being set so that the shaker and carrier shall travel in opposite directions to each other. 8th. In a thrashing-machine provided with a dressing-shoe K, at one end, and a combined smatter and fanning-mill at the other end, an elevator L arranged to convey the grain from the dressing-shoe K to the chamber N, in combination with the worm-conveyor 0, arranged to carry the grain through the 'chamber N to the smatter, substantially as and for the purpose specified. 9th. In a thrashing-machine, in which the grain is conveyed from the dressing-shoe K to the chamber N, by the elevator L, a revolving worm conveyor 0, in combination with the slide T, substantially as and for the purpose specified. 10th. In a thrashing machine, a chamber N, provided with a worm conveyor 0, in combination with the smatter barrel P, having a roughened interior surface and revolving beaters Q within it, substantially as and for the purpose specified. 11th. In a thrashing-machine, a smatter barrel P, provided with revolving toothed beaters Q, the teeth in the said beaters being set spirally, so as to convey the grain from the mouth of the conveyor to the port where it is discharged from the smatter to the finishing sieve B, in combination with the fan 5, arranged to send a blast through the grain, as it falls from the smatter-barrel P to the finishing sieve P.
