COMBINED CLOVER THRASHING AND HULLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 255,097, dated March 21, 1882.

Application filed July 18, 1881. (No model.) 7

To all whom it may concern:

Be it known that I, J. BENJAMIN BIRDsELL, of South Bend, county of St. Joseph, State of Indiana, have invented a new and useful Improvement in Combined Clover Thrashing and Hulling Machine; and I do declare the following to he a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawing, which forms a part of this specification.

My invention consists of the combinations of devices and appliances hereinafter set forth, and more particularly pointed out in the claims.

The drawing is a side elevation of a combined clover thrashing and hulling machine, representing in dotted lines the interior operative mechanism.

A is the frame of the machine; B, its thrashing and 0 its hulling cylinder.

1) I) are any ordinary separating-bolts.

E is a tight board beneath the bolts, upon which the seed and chad drop, and it is so \'ibrated with a downward-and-forward movement that the said materials are constantly worked back and delivered at 6 upon the hulling-cylinder.

F is a traveling belt of raddles which draw the seed and chafl' as they emerge from the liulling-cylinder up along the inclined floorf beneath and deliver it upon the sieves of the shoeeG.

H is the fan which cleans the seed in the ordinary way.

Iis the tailings spout,from which the tailings are delivered into an elevator, J, and are elevated, not, asheretofore,back into the thrashing-cylinder or upon the bolts, but up onto the tight board E, which directs them back through the hulling-cylinder without going again over the bolts. This is one of the essential features of my invention. It avoids the useless waste of power used to rebolt. It obviates the liability to clog up the bolts, and dispenses with what has heretofore been a useless operation upon the chaff and tailings.

S is a shaft, provided with projecting wire fingers of usual form, located over the bolt D in rear of the cylinder, which fingers prevent any clogging at this point, and a winged shaft,

S, located in the hopper of the hulling cylin der, keeps the material at all times'feeding down upon the huller. The separators D D and the tight board E are all of them agitated by the shaft T. Their respective cranks are arranged at thirds about the shaft, so as to give them counter movements, and thus neutralize to a great extent the usual shaking of the machine. Arms T T T unite the said cranks t 15 t respectively, with the bolts D D and board E. The board E at its forward end is bent downward, so as to leave room between it and the bolt D for a spiral conveyer, E, which delivers the tailings from the elevator across upon the board E. This bent portion E of the board is provided with a serrated surface, so as more readily to feed the tailings backward and prevent them from dropping downward and forward by gravity.

At the rear end of the bolt D is a tight floor, U, beneath, and secured by side boards to the bolt D. The office of this tight floor is to direct such heads and chaff as may fall upon it forward to the hulling-cylinder.

I am aware that a clover thrashing and hulling machine has been provided with devices for conveying tailings back to the huller after they have passed through the same; and Ido not claim such construction broadly.

What 1 claim is- 1. In a combined clover thrasher and huller, the combination,with the bolting devices and hulling mechanism, of the tight shaking floor under the bolts, arranged to carry the materials passed through the bolts to the huller, and the elevating and conveying devices, substantially as described,'arranged to take the tailings from the tailings-spout of the huller and deliver them upon said tight floor to be reconveyed to the huller.

2. In a combined clover thrasher and huller, the tight conveyingfloor having its outer end bowed downward, in combination with the huller, the elevator J, and the spiral conveyors I and E the latter of which is arranged over said bowed end of the conveying-floor, substantially as and for the purpose set forth.

In testimony whereof I sign this specification in the presence of two witnesses.

J. BENJAMIN BIRDSELL.
