BAND-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 716,022, dated December 16, 1902.

Application filed November 25, 1901I Serial No. 83,548. (No model.) 7

To all whmn it may concern.-

Be it known that I, HENRY J. FOURTNER, a citizen of the United States, anda resident ofHazleton, in the county of Buchanan and Stateof Iowa, have invented a new and improved Band-Cutter and Feeder, of which the following is a full, clear, and exact description.

The invention relates to threshing machines, and more particularly to band-cutters and feeders thereof, and preferably to such as are shown and described in the Letters Patent of the United States, No. 594,784., granted to me November 30, 1897.

The object of the invention is to provide a new and improved band-cutter and feeder. arranged to properly cut the bands of the sheaves, to spread the same after the band is cut, and to feed the grain to the drum of the threshing-machine in quantities corresponding to the capacity of the drum to prevent overfeeding and consequent bad threshing of the grain.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied. Fig.2 is a rear side elevation of the same. Fig. 3 is a longitudinal sectional elevation of the same. Fig. 1 is a plan View of the shaking conveyer. Fig. 5 is a plan view of the cutter, spreader, feeder, and the drum of the threshing-machineJ Fig. 6 is an enlarged side elevation of the fastening device for the cutter-knives. Fig. 7 is an enlarged cross-section of one of the cylinders for carrying the knives or hooks, the section being'taken on the line '7 7 of Fig. 8; and Fig. 8 is a longitudinal sectional elevation of the same.

The improved band-cutter and feeder in its general construction comprises a feeder A for conveying the sheaves to the revoluble cutter B, which serves to cut the bands of the sheaves, the cutter operating in conjunction and in unison with a revoluble spreader O for spreading the grain after the bands are out,

the sheaves then being fed by a revoluble feeder D to the drum E of the threshing-machine, the loose chaff and straw that may drop from the inner end of the conveyer A and from the feeder D being fed to the bottom of the drum E by a shaking conveyer F. The parts of the band-cutter and feederare mounted on a framework G, which may be part of the threshing-machine, as indicated in the drawings. p

The conveyer A is in the form of a belt of any suitable construction and is arranged with an outer upwardly and inwardly inclined leg A and a shorter inner leg A inclined downwardly and inwardly, the outer leg A carrying the sheaves to the knives B of the cutter B, located at the apex of the conveyer A. The shorter inner leg A of the conveyer extends under the spreader C, and its lower inner end discharges the chaff andloose straw onto the shaking conveyer F.

Theknives B of the cutter B extend from the peripheral surface of acylinder B and said knives are curved and arranged in spiral rows starting from near the middle of the cylinder and running to the ends thereof, as indicated in Fig. 5. Thespreader C is provided with curved hooks 0, extending from the peripheral surface of a cylinder 0 and said hooks C are likewise arranged in spiral rows extending from one hook, which is common to both rows and located at the middle of the cylinder outwardly to the ends thereof, but in such a manner that the hooks 0 pass corresponding knives B ofthe cutter B when the machine is in operation. As indicated in Fig. 5, the knives in the two spiral rows are arranged in pairs, and the knives in one row have a sharper curve than the knives in the other row, as will be understood by reference to Figs. 1 and 2.

The books D of the feeder D project from the peripheral surface of'a cylinder D and are arranged in transverse rows, with the hooks standing close together but arranged in such a manner relative to the hooks O that the hooks C andD readily pass each other when the machine is in operation. The hooks D are curved, but comparatively shorter than the hooks B and C, as indicated in Figs. 1 and 2.

IOC

The cutter B, as previously mentioned, rotates in unison with the spreader C, and the cylinders are so arranged that the middle hook of the spreader C passes between the two innermost knives of the cutter B and the pairs of following hooks and knives correspondingly pass each other for the hooks to cut the band and to operate in unison with the hooks O to properly spread the sheaves after the \bands are cut. each pair are given different curvatures to prevent a sheaf from passing the cutterB Without the band being cut, it being evident that the knives act on the sheaves one in advance of the other to strike at dilferent points on the sheaves to positively cut the band.

The band-cutter B is driven from the drum E of the threshing-maehine, and for this purpose the shaft B of the cutter is provided at one end with a pulley H, over which passes a belt H, also passing over a pulley H secured on the shaft E of the drum E. Thus when the threshing-machine is set in motion a rotary motion is transmitted from the drum E to the eutterB to rotate the latter at a considerably lower rate of speed than the drum E. As previously mentioned, the shaft B and the spreader C rotate in unison, and for this purpose the shaft 13 is provided with a sprocket wheel I, over which passes a sprocket-chain I',also passing over a sprocketwheel I, secured on the shaft 0 of the spreader O, the sprocket-wheels I and I being of the same diameter. The feeder D is rotated at a higher rate of speed than the cutter B and spreader O, and said feeder is driven from the shaft B and for this purpose the shaft B is provided with a sprocketwheel J, over which passes a sprocket-chain J, also passing over a sprocket-wheel J secured to the shaft D of the spreader D, the sprocket-wheel J being larger in diameter than the sprocket-wheel J. A tightening sprocket-wheel J (see Fig. 2) engages one run of the sprocket-chain J to give the desired tension to the latter.

The conveyer A is driven from the cutter B, and for this purpose the shaft B thereof is provided with a pulley K, connected by a bolt K with a pulley K held on the shaft L, carrying driving-wheels L for imparting a traveling motion to the conveyer-belt, as will be readily understood by reference to Fig. 3, said conveyer-belt passing over sprocket- Wheels A A and A journaled in suitable hearings on the frame G, the lower run of said conveyer-belt also passing over a sprocketwheel A located near the sprocket-wheel A A belt-tightener K is provided for the belt K, and the pulley K is provided with a frictiongovernor of any approved construction, so as to govern the speed of the conveyer-belt A and prevent overfeeding of the sheaves to the cutter B.

The shaking conveyer F operates in conjunction with the conveyer A, and for this purpose the shaft A of the sprocket-wheel A The knives B in carries a sprocket-wheel 0, over which'passes a sprocket chain 0', also passing over a sprocket-wheel 0 attached to a crank-shaft P, journaled in suitable bearings on the frame G. Said shaft P is provided with crankarms P, (see Fig. 4,) engaging bearings F on the shaking conveyer F, which latter is in the shape of a table hung at its outer end on said crank-arms and resting at its free inner end on the bottom leading to the threshing-drum E. The table F is provided on its top surface with the usual notched longitudinallyextending bars F so that when the material falls upon the shaking conveyer and the latter receives a forward-and-backward shaking motion then said material is fed inwardly and finally passes upon the bottom to the drum E to be threshed.

The cylinders B C and D alike in general construction, as illustrated in Figs. 7 and 8-that is, each cylinder is provided with solid cylinder-heads B on which are secured the transverse bars B, supporting keepers B for receiving and carrying the knives and hooks B, C, and D.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A band-cutter and a feeder for threshing-machines, comprising a revoluble cutter having curved cutting-knives, a revoluble spreader adjacent to said cutter and having curved hooks, the knives of the cutter and the hooks of the spreader being arranged in spiral rows extending from the middle of the cutter and spreader to the ends thereof the knives of each row having different curvatures, the knives and hooks operating in conjunction with each other for spreading the grain after the knives have cut the bands of the sheaves, and a revoluble feeder rotating at a higher rate of speed than the cutter and spreader, said feeder having short curved hooks arranged in transverse rows, the hooks in arow standing close togetherand the hooks serving to take the sheaves from the spreaderhooks and to lift the butts of the sheaves and feed the latter to the drum of the threshingmachine, as set forth.
