BAND-CUTTER AND FEEDER FOR THRASHINGuiVl/CHINES.

GPECEFICATION forming part of Letters Patent No. 309,074, dated December 9, 1884.

Application lerl June 18, i854.

` To all whom, it may concern:

Be it known that we, J osnrn AMARSHALL and FLAvrUs H. MAnsHALL, citizens of the United States, residing at Darlington, in the county of Montgomery and State of Indiana, have invented certain new and useful Improvements in Band-Cutters and Feeders for Thrashing-Machincs, and we do declare the following to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which-it appertains to make and use the same, reference being had to the`aecompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a side view of our device. Fig. 2 is a plan view of the same, and Fig. 3 is a detail view.

This invention is an improvement on the patent grantedto us on the 29th day of Jaa' nary, 1884, and numbered 292,667; and it relates particularly to an improved form of feeding device in place of that used in the abovementioned patent.

The invention consists, essentially, in constructing the feeding mechanism for the thrasher in the following manner: A proper number of boards having upright serrated edges are attached to a rod by the end that adjoins the carrier in such manner as to haveV a longitudinal reciprocating movement. The said rod connects two brackets hinged to the earrier, and lies below the level of the carrierapron. The ends of the boards adjoining the thrasher are reciprocated and vertically vibrated by means of eccentrics fixed on a transverse shaft, which is driven by a pulley on one of its ends and a belt connecting the same with a pulley at any proper point on the thrashing-machine. Each eccentric is set on the ,shaft in an opposite direction from those adjoining; consequently any two adjacent boards will both vibrate and reciprocate alternately, by the former motion shaking and loosening the cut bundles, and, by the latter, in consequence of the serratededgcs, carrying the same toward the thrasher.

In the accompanying drawings, A represents the front or receiving end of a thrashing-machine, of which a is the cylinder-shaft, carrying the cylinder a', and having on either end a driving-pulley, c2, the opposite end being (No model.)

l provided with a pulley, a, to actuate by means of a proper belt the shaft having the eccentrics attached.

B is a chute inclined from the carrier to the thrashing-machine, one end ofwhich is pivoted or hinged between the outer ends of the projecting top sills of the thrasher-frame, below the connecting-brackets D D, and the other end loosely attached to the front of the thrashing-machine below, and in proper relation to the cylinder c. The said chute is provided with upright sides, in which is transversely journaled the eccentric shaft b, provided on one end with the pulley b, and on the other with the pulleys b2 and b3, the former of which is driven by a belt from the pulley a.

bL b4 are the eccentrics, set at equal distances apart on the shaft b, each being set in an opposite direction to the adjoining ones.

C C are the shaking-boards, each provided along its sides with the upright teeth or serrations c c, the vertical edges of which are toward the thrasher and the inclined edges toward the carrier, the said teeth increasing in height as they approach the thrasher. The boards C G have just sufcient space between their edges to move without binding,and each is attached toan eccentric by a band, c', which depends from thelower surface andits around the eccentric, the latter turning freely in it.

If desirable, cranks may be substituted for the eccentric, the cranks turning in proper openings or loops fixed to the lower surfaces of the boards; but the eccentrics are preferable. Each of the boards Chas fixed to and depending from the lower surface oi' its end nearest the carrier a rectangular strap, ci, through which passes a transverse rod, d, that connects the lower ends of the bracketsD D. Thesaid strap is just sufliciently wide to admit the rod, but is sufficiently long to allow the board to be reeiprocated by the rotation of its attached eccentric.

D D are the connecting-brackets, pvoted to and vertically adjustable on the inner ends of the carrier E by means of proper pins or rods, d, and any two opposite holes, e e, the holes being in vertical series one above another and at equal distances apart on each side of the carrier.

e and e2 are the rollers for the carrier-apron, having bearings in the frame of the same, the

IOO

former adjacent to the brackets D, and the p latter at the'ropposite end of the frame, and es I lower ends resting on the ground when the carrier is in working position. rlhe said legs are turned up on the sides of the carrier and the carrier is folded over the top of the thrashing-machine when it is necessary to move the latter. Y

e8 is a pulley on the end of the journal of the roller e2, outside ofthe carrier, and situated on the same side of the machine as the pulley b, being driven bya belt from the same. Acone of pulleys may,if dcsired,be substituted for the pulley e, so as to give the apron-rollers a greater or less speed, the slack of the apron being taken up, when necessary, by the sliding boX c5 and screw of. The pulleys which drive the carrier-rollers may be arranged in either side of the machine that is desirable.

F F are similar vertical brackets, pivoted to the top of each side of the carrier-frame, at opposite points on the saine, and having journaled in them the transverse shaft f.

j is a pulley on the end of said shaft, outside of the carrier, and situated on the same side of the machine as the pulley b3, by which it is driven by means of a cross-belt.

f3 f3 are disks provided with continuous cutting-edges, which disks `fit'upon the shaft f, and haveinterposed between them the equal and similar washers, f 4 f 4. The said washers and disks are secured in place by means of a collar, f5, fixed to the shaft on one side of them, and a'nut, f6, screwing tightly against them on the other side, over a threaded portion of the shaft. The ends of the shaft f are adjustable in ther brackets 'FF by means of the upward-extending arms of said bracket and the horizontal set-screws f7 f7 engaging said arms.

The operation of the machine is as follows: The bundles are fed to the carrier, which moves them at a greater orless speed (if conepulleys are used) toward the cutting-disks. After they are cut by the latter they are thrown into the shaking-boards,vvhich spread them and deliver them upon the chute, whence they fall into the thrashing-machine.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

In a feeder for thrashing-machines, the combination of the carrier-frame E, having vertical series of adj ustment-holes e, the thrasherframe brackets D, and pins or rods d,whereby the said carrier-frame may be vertically adjusted with relation to the thrasher, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
