BAN D-CUTTER AN D FEEDER.

SPECIFICATION forming part of Letters Patent No. 448,102, dated March 10, 18791. Application filed July 16, 1890. Serial No. 358,911. (No model.)

To @ZZ whom t may concern:

Beit known that I, EDMUND S.W1LHIrE,a citizen of the United States, residing at IVest Salem, in the county of Edwards and State of Illinois, have invented certain new and useful Improvements in Band-Cutters and Feeders, of which the following is a specification.

The present invention relates to band-cutters and feeders; and it consists in the novel arrangement and construction of parts, as will be hereinafter fully set forth and claimed.

In the accompanying drawings, making part of this application, Figure l is a top plan view of a band-cutter and feeder constructed according to my invention and attached to the front end of a thrashing-machine. Fig. 2 is a section taken on the plane indicated by the line o: Fig. l. Fig. 3 is a side elevation thereof with the side-boards and supports removed, showing part of the device folded. Fig. a is a detached view of the shaft carrying the knife-holders' and knives. Fig. 5 is a cross-section of one of the knife-holders, showing a knife secured therein. Fig. 6 is a modification of the knifeholder, showing the grain-spreading portion. Fig. 7 is a perspective view of the slidingboard, showing the rack-bars and lingers. Fig. Sis a perspective view of a modification thereof. Fig. 9 is a perspective view of the ilanged bracket. Fig. l0 is an enlarged sectional view of the knife-holder, showing` means of securing the knife thereon; and Fig. 1l is a top view of the holder with the knife removed.

The saine letters of reference denote the saine parts throughout the several figures.

The rear frame A of the band-cutter and feeder'is constructed in the usual way, so as to conform to the front of a thrashing-machine B, and is attached thereto by means of bolts a', which pass through the respective frames and `receive suitable nuts ct.

The'fraine A has attached on either side near its top a hinged plate l), having a crooked or curved end projecting beyond said frame which is provided with an aperture b', which registers with an aperture in a like plate h2, secured to the top'of the uprights A. A brace C is attached to the frame A at one end, while the other end is attached to the front of the thrashing-machine. By this hinged attachment the bandcutter and feeder can be lifted up and thrown backward, leaving the front of the thrashingmachine exposed and rendering it more convenient to be cleaned or repaired without detaching the band-cutter and feeder from the machine.

D represents the receiving-box for the sheaves, and is hinged or pivoted to the lower frame cl by means of hinge-brackets d', secured to said box and frame on either side.

The box D has detachable side-boards cl2, which are provided with angle-pieces (Z3, arranged to enter supporting-brackets d4 on the outside of the box D at either end, and in the center of said sides is a like bracket d5, which rests on the shoulder of a supportingleg d, made in two parts, each part being provided with a rectangular sleeve di, having a screw-threaded aperture to receive a suitable set-screw, by means of which and the said sleeves the supporting-legs d6 can be adjusted when the machine is located on uneven ground. One of the sleeves dl, being secured to the opposite ends of the two parts which form the supporting-legs d6, allows such parts to slide upon each other when released by the set-screws. The middle portion of the iioor D of the receiver D is made in two parts and hinged at the back and front for convenience in folding.

In folding the box D back; as shown in Fig. 3 of the drawings, the side-boards and supporting-legs are removed, leaving the box and endless apron free to be carried backward and hooked to the rear of the band-cutter and feeder.

E denotes an endless carrier apron, upon which the sheaves are thrown and carried into the machine by a series of crooked or bent spikes E', projecting from the slats or cross-bars F2 of the apron E, which is propelled by a drive-chain e, attached to the' ends of the cross-bars E2 of the apron, engaging a sprocket-wheel c on the shaft F at the front of the box D and a like sprocket-wheel f on the shaft f', said shaft being driven by a suitable driving-pulley. l

The front frame Gr is provided with brackets I-I, having a flange g and a right-angle projection h, which has an aperture g. These brackets are secured lon the outside of the IOO frame on either side so as to leave sufficient space between the flange g andthe front of the frame G for a sliding board H, which is provided at either end on its front with rackbars h and along its lower portion with curved teeth or guide-lingers h2. This board H is moved up and down, according to the size of the sheaves, by means of two gear-wheels H2, located on the ends of a shaft H3, which is provided with a handle HA1 securely attached thereto, and which extends upward from the said shaft. Suitable pawls h* are provided, so as to catch and hold the board H in whatever position it is placed by moving the handle H, and hence the shaft H3 and the wheels H2, which gear into the rack-bars h', as clearly shown in Figs. l and 7.

The above-described board, with its tin gers,

forms a regulating device for the sheaves and only allows a proper number of them to be carried into the machine at once. A modified form of such regulator' is shown in Fig. 8 of the drawings, wherein the board H extends entirely across the apron E on which the sheaves are deposited, and is secured to the front frame G by set-screws or bolts which pass through slots g2 and leave the board free to move up and down and not choke the feed.

Just behind lthe finger-board H and at a suitable distance from and above the endless apron is located a shaft I, provided with a pulley t' and journaled in the sides of the cutting and feeding machine. Secured on this shaft I by set-screws i are a series of knifeholders or blocks K, one side of which is straight and provided with a recess into which is fitted the shank of a knife L; or the holder may be cut out to receive a nut after the shank has been placed into it, which nut receives a bolt passed through the holder and knifeshank, thus holding the knife iirmly in place. The holders, with the knives, are placed on the shaft in the form of a right-hand screwthread, so that when the cut-tin g has been accomplished the spiral motion of the knives will spread and move the sheaves into the machine.

The knife-holders may be constructed so as to form a grain-spreader by casting or forming prongs Zonthe opposite side of the holder from the knife, in which case a less number of knives are necessary. It will be observed that in operation the cutters or knives L and the prongs or spreaders Z alternate each other in their action on the sheaves, so if cut by any one knife it will be spread by the spreaders l of the knife-holder K located fon either side of the particular knife having done the cutting.

The front and rear frames, 1espectively,have jonrnaled thereon cone-pulleys M, connected by a belt m, and are driven by a belt m', which passes from the rear cone-pulley around a pulley m2 on the shaft I, which shaft is driven by a main driving-belt from an engine or other motive power and passes around the pulley N of athrashing-cylinder. On the outside shaft of the front cone-pulley there isa pulley n', which has a Vbelt n2 driven by said pulley n and by means of which the pulley O on the shaft f, which carries the sprocketwheels j', is actuated, which actuates the endless apron. The speed of the endless apron is regulated by means of a belt-guide P, having a screw-threaded aperture P', through which a rod p extends across the top of the machine between the two conepulleys, which is journaled in the uprights p. The rod p 1s provided on one side outside such upright with a crank-handlepi, which by being turned causes the belt-guide P to move the cone-pulley belt, and thus through the medium of the belt and pulley connections to the endless apron, heretofore described, causes the speed of said apron to either increase or decrease, as desired.

A suitable beater R is provided in the rear of the machine and is actuated by a belt r from the front cone-pulley.

A shaker S is provided at the rear of the endless apron, from whence the grain is shaken olf into the thrashing-machine. This shaker is secured at one end toa rod S', which extends across the machine and is journaled in the short arm s of the pivoted crank-arm T. The long arm s of the crank-arm is provided with a weight T. A pawl t is secured on the end of the rod S and extends in a bent position up over a ratchet-wheel t on the end of the shaft f', and is provided with an enlai-ged head 252. By the rotary movement of this shaft f the ratchet-wheelt is rotated and the head t2 of the pawl engaging said ratchet the shaker is moved up and down and the weight T counterbalances the shaker and tends to keep it in its normal position. Although but one crank-arm and its attachments have been described there are two employed.

A right-angled rod U is suspended loosely on the shaft H3 with its horizon-tal portion u lying parallel with the endless apron and its end resting in a bracket V in the center of the box D, so as to prevent the sheaves from entering the machine crosswise and to keep them in proper position to be cut. lVhen the machine is folded, as shown in dotted lines, Fig. 3, the rod U is thrown back on top of said machine, so as to be entirely out of the way when the machine is transported.

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

l. In a band-cutter and feeder, the combination, with the shaft I, of a series of combined knife-holders and grain-spreaders arranged spirally upon the said shaft, and the cui ved knives secured in the said holders opposite the said grain-spreaders, substantially as shown and described.

2. A combined knifeholder and grain spreader constructed in one piece and having a central aperture, said holder being .recessed on one side to receive the shank of a IOC) IIO

knife, the opposite side having spreading prongs formed thereon,substantially as shown and described.

3. In combination, in a hand-cutter and feeder, substantially as shown and described, a crank pivoted toY the side frame 0f the cut-- ter and feeder, the long` arm of which is provided With a weight and the short arm adapted t0 form a journal-bearing, of the shaker, se-

cured at one end io a rod located inside said 1o cutter and feeder and the other end extending outside, 'for the purpose set forth.

In witness whereof I hereunto set my hand in the presence of 'nwo witnesses.
