BAND-CUTTER AND FEEDER FOR THRASHING-MACHINES.

SFECIFIOATION forming part of Letters Patent No. 524,48 4, dated-August 14, 1894.

Application filed November 21,1893. Serial No. 491,550. (N modem To all whom it mag concern:

Be it known that I, JOSEPH HOVEY, a citizen of the United States, and a resident of Florida, in the county of Henry and State of Ohio, have invented certain new and useful Improvements in'Grain-Separators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawlugs, and to the letters or figures of reference marked thereon, which form a part of this specification.

Figure l is a longitudinal vertical section of a portion of a thrashing machine embody- Figs. 2 and 3 are side elevations of the same from opposite sides, with the bundle carrier folded back. Fig. 4 is a detailview of the band cutter. Fig. 5 is an end view of the crank shaft which actuates the vibratory arms N. Fig. 6 is a detail view of one of the rocking levers. Fig. 7 is atransverse vertical section of Fig. 1, taken just back of the band cutter and looking toward the cylinder, and Fig. 8 is a detail view of one of the ribs P This invention has relation to certain new and useful improvements in band cutters and feeders for thrashing machines; and has for its object the provision of practical and efficient means for severing the bands of the bundles as they pass from the bundle-carrier to the feeder.

further object of the invention is the provision of improved means for securingauniform distribution and regular feed of the grain as it passes from the band cutters to the separator.

A further object is to improve the general constructlon and arrangement of parts, all as will hereinafter appear.

With these objects in View, the invention consists in the novel construction and combination of parts all as hereinafter described and pointed out in the appended claims.

Referring to the accompanying drawings, the letterAdesignates the main frame of the separator, which may be in general of any ordinary construction; having the extension B of general triangular form, which forms the through.

entire throat or mouth of the machine. Rising from the side sills a, a of this extension, one at each side, are two posts or uprights G. Secured to the faces of these uprights, near their upper ends, are bearings 11, which support a transverse shaft D, carrying a hollow roll E. Upon this roll E, is fastened a series of knives E, each of which is set somewhat obliquely to the axis of the roll, and at difierent angles to a plane passing there- Each of said knives has a curved edge 61 which is of serrated or sickle character, and forms the cutting edge, its curvation being such that as it revolves it will act with a continuous drawing stroke. Secured to the frame above this roll E is a sheet metal guard F which extends downward and forward of said roll, and is bent rearwardly underneath the same to the rear thereof, as shown in Fig. 1. Slots are formed in said guard through which the knives work. This guard serves to prevent the grain from being wound around the roll as it is rotated.

G, G designate brackets secured one to each of the posts or uprights 0, below the bearings b, said brackets forming bearings for a transverse shaft G which carries wheels or pulleys fwhich drive the webs, belts or chains G of the bundle carrier H, the discharge end of which is supported by said brackets G, G. Said bundle carrier is cut transversely at g, and jointed so that it may be folded up back against the mouth B of the separator when desired. Attached to the discharge portion of the carrier, near said joint and also to the extension B, one at each side, is a rod or link h.

Secured to the sills a a, just forward of the uprights C, are bearings t', in which is journaled a transverse crank-shaft I, which has a crank I at each end. Upon these cranks are journaled the upper, lateral portions of an inclined, vibratory bottom J whose rear end extends to the concave J of the separator, and rests and slides upon blocks j, secured to the depending frames j. To close the gap formed by the vibration of the table or bottom J, between it and the concave J i ,a hinged gate or extension J is provided, said gate or extension being free to slide upon the flange of ,the concave upon the vibration of the bottom. Secured to the upper face of said table or bottom along its upper half is a series of ribs K, notched or toothed along their upper edges. These ribs upon the vibration of the table or bottom, serve to shake, loosen, and distribute the bundle after its band has been cut, and also to push or feed it forward and downward.

The depending frames'j above referred to are usually bolted to the under side of the sills a. a, or otherwise secured just forward of the cylinder L, and form the support for the regulating and feeding device now to be described.

M designates a transverse crank-shaft journaled in bearings Z and having a series of cranks Z. ferent directions, or at different angles, as seen in Fig. 5. In the drawings I have shown the shaft as provided with eight cranks, but a greater or less number may be employed. J ournaled on each of said cranks is an arm N, loosely connected at its lower end portion to the end portion of a rocking lever N, which is fulcrumed upon a transverse rod or barf, a series of such levers being provided, one for each of the arms N. The upper end portions of said arms N are reduced in size, forming elongated points n which project up through elongated slots 0 in the table or bottom J, said slots having raised guards O to prevent the grain falling through. The cranks Z have a stroke of about four inches, and the arms N are journal'ed thereon. Upon the rotation of the. shaft M,these arms are given a vibratory, oscillating movement, causing their upper portions to play back and forth in the slots 0. The cranks Z all being at different angles, it follows that no two of the arms N will be in the same position at the same time, and the result of this arrangement, in connection with the peculiar fmo-vement of each, I find to be very efiective in feeding the grain evenly to the cylinder. The rocking levers N, as shown in Fig. 6 are preferably forked at one end to embrace the arms N, and at the other end to give them a wide bearing upon the fulcrum rod.

P designates the top lid or cover of the feeding chamber which is hinged at its upper forward edge to a cross-piece P connecting the posts or uprights G. On the under face of said lid or cover are triangular ribs P widest and thickest at their lower ends, their upper ends terminating short of the upper end of the lid or cover. The purpose of these ribs is to aid in breaking up and distributing the bundles.

The vibratory bottom or table may be raised to the position indicated by the dotted line X- Fig. 1 giving sufficient room to permit a man to work at the cylinder.

R, R designate brace rods from the under side of the forward end of the sills a a to the bolster of the separator. for the vibratory table.

The various parts may be driven as foll'owsz-On one end of the cylinder shaft isa S, S are side guards 1 pulley 1 from which runs a belt 2 to a large pulley 3 on one end of the shaft D which carries the cutter-roll E. On the opposite end of the shaft D is a pulley 4 connected by a crossbelt 5 with a pulley 6 on the crank-shaft 1. Behind the pulley 6 is a sprocket wheel 7 which drives the shaft G by means of a chainbelt 8. Upon the other end of the shaft G is a pulley 9, which drives the crank-shaft M by means of a pulley 10 thereon and a connecting belt 11.

The operation of the various parts is believed to be fully apparent from the above description. Preferably all projecting in dif- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
