GEORGE ll. MORRIS, OF BRANTFORD, OJTARIO, CANADA.

TH RASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 373,678, dated November 22, 1887.

Application filed April 15, 1885.

Serial No 162,310. (No model.)

To all whom it may concern.-

Be it known that I, Gnonen \VILLIAM Mon- RIs, of the city of Brantford, in the county of Brant, in the Province of Ontario, Canada, manufacturer, have invented acertain new and useful Improvement in Thrashing-Machines, of which the following is a specification.

- This invention relatrs to thrashing-machines; and the novelty consists in the peculiar combination and the construction and arrange ment of parts hereinafter more fully described, and then pointed out in the claim.

Figure l is a perspective view with part of easing removed so as to exhibit the strawshaker and grain-deck. Fig. 2 is a perspective view with part of easing broken away so as to exhibit the location and interior of the smutter. Fig. 3 is a side elevation, partly in section, with smutter and other matter removed.

It will be noticed that the straw-shaker is divided into three sections, A, B, and O. The lower end of sections A and C are carried on apair ofhangcrs, D, only one of which is seen in the drawings; but it will be understood that a corresponding one is placed on the opposite side of the machine. The lower ends of these hangers are connected by a bar, (not shown,) which bar passes under and is secured to the sections A Gin any convenient way. A similar pair of hangers, E, carry the center section, B, the rod connecting the pair of hangers E passing below and clear of the outer sections, Aand O, and their upper ends connected to the crossbar c, suitably secured at the front end of the machine.

F is a shaft having three cranks, the two outer cranks extending in the same direction and being connected to the sections A and C, while the center crank, extending in a direction opposite to that of the outer cranks, is connected to the center section, B, ordinary beal'ingboxes being provided for that purpose. All three sections A, B, and G of the strawshaker are formed substantially in the same way, each having two side rails, the tops of which are connected together by a series of diamond-shaped slats, the lower ends of the straw'shaker A, B, and 0 being covered by perforated sheet'iron, so as to resist the extra wear on that portion of the strawshaker immediately below the beater.

G is the grain deck suspended by four spring-hangers, H, two of which are seen in the drawings, the other two being on the opposite side of the machine. Each pair of hangers is connected by a rod passing under the grain-deck. Only a portion of one of these rods is shown at h, Fig. 1.

I is the sieve-extension of the grain-deck G. Its end is supported by a pair of spring-hangers, J, only one of which is seen, the other being on the opposite side ofthe machine. These hangers J are connected by a rod,j, which passes under and supports the free end of the extension I, and are set slightly more perpendicular than the hangers H, so that the sieveextension I, which is hinged at a to the grain deck G, has a motion imparted to it slightly different from the grain-deck G, which is connected to the center-shaker, B, by thepitrnan or rod K. WVhen the crank-shaft F is caused to revolve, the sections A andO of the straw shaker move together, while the center section, B, moves in an opposite direction from A and C; and as it is connected to the grain-deck G by the pitman or rod K,the grain-deck moves with the center section, B, while the sections A and O of the straw-shaker move together in the opposite direction; consequently the graindeck G and center section, B, counterbalance the two sections A and C. If the grain-deck and center section should be heavier than the two outer sections, A O, of the straw-shaker, or vice versa, the crank driving the lighter pair is made so as to have slightly more throw than the heavier pair, so as to compensate for the difi'erence in the weight. By thus utilizing the grain deck to balance the straw-shaker I am enabled to get a straw-shaker with great vibratory movement without inj uriously shaking the machine when in operation.

As shown in the drawings, the bottom of the grain-deck G is made of corrugated iron, which has the peculiar advantage of forming aseries of receptacles to receive and hold the grain, so that the grain will be carried up the graindeck toward the sieveextension I by the reciprocating action of the graiirdeck G, whereas if the deck G were a plain surface, the grain would naturally fall toward the lower end. After the grain falls through the sieveextension I it passes in the ordinary way through the fanningmill screen, and finally finds its way into the spout L, from which spout in ordinary thrashing-machines it is discharged; but in my construction I place an elevatorbox, M, so that the grain Will discharge from the spout L into the box M. The buckets N of the elevator will then convey the grain from the elevator-box M into the smutter-barrel O. From this barrel it passes through the ordinary sieves and screens and is finally discharged into the conveyer P, which may be made to revolve in either direction, so as to carry the grain to either side of the machine, a spout, Q, being placed at each side.

As I do not claim anything peculiar in the construction of the smutter, and as any smutter would answer the purpose, it is not necessary for me to describe in detail its specific construction. The points to be observed are, first, that the smutter should be placed on the top of the machine, so that the grain passing through it can readily be handled, so as to be discharged from either side of the machine; secondly, that the bottom oftlie smutter shall communicate directly with the interior of the thrasher, so that any tailings or grain that may fall with the tailings shall be discharged back onto the straw-shaker and be again carried through the machine.

What I claim as my invention is-- The combination,with the straw-shaker and V the smuttcr arranged above and communicating directly therewith, of the spout L, the elevator-box M at the discharge end ofsaid spout, connecting said spout directly with the smutter, and the elevator in said box, all substan- 5 tially as described, and for the purpose specified.
