CARL H. ZISHKA, OF SPENCER, IOWA.

BAND-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 504,383, dated September 5, 1893.

Application filed February 25, 1893- Serial No. 463,716. (No model.)

To all whom it may concern.-

Be it known that I, CARL H. ZISHKA, acitizen of the United States, residing at Spencer,

in the county of Clay and State of Iowa, have invented a new and useful Band-Cutter and Feeder, of which the following is a specification.

- This invention relates to band cutters and feeders for thrashing machines; and it has for its object to provide certain improvements in machines of this character, whereby the cutting of the bands of every bundle is insured, as well as an equal distribution of the grain into the cylinder end of the thrasher.

To this end the main and primary object of the invention is to provide certain improvements in the general construction of band vention. Fig. 2 is a central vertical longitudinal sectional view of the same. Fig. 3 is a central vertical sectional view on the line a:a: of Fig. 2. Fig. 4 is a detail in perspective of one of the inclined notched feed plates. Fig. 5 is a bottom perspective view of the upper vibrating feed box. I

Referring to the accompanying drawings, A represents a rectangular truckframe mounted on the supporting wheels B, which provide 3 means for transporting the machine independently of the thrasher, from place to place, to facilitate the placing thereof into and out of position for work.

Arising from opposite sides of the rectangula'r truck frame A, are the frame uprights B, supporting a raised horizontal frame C, inside of which moves the longitudinally reciprocating and oscillating bundlecarrier pan D. The longitudinally reciprocating and oscillating bundle carrier pan D, is providedwith the inclosing outwardly flared sides E, which serve to allow the bundles to be easily thrown into the said pan, and the same is further provided with overlapping bottom boards E, forming a notched bottom the shoulders of which are disposed toward the inner open end of the pan so as to force the bundles under the cutters to be described.

Secured longitudinally on the notched bottom of the bundle carrier pan D,and parallel with each other are the notched feed bars F, extending from end to end of the pan, so as to provide intermediate spaces to force the bundles on the bottom of the pan under the knives, while at the same time by this construction of pan, the bundles are forced under theknives either head or butt first, and if two or more bundles are piled on top of each other in the carrier, the top bundles slide back while the bottom bundles are carried upward and under the knives. The latter eflect is due to the reciprocating-oscillatory movement of the pan, as Well as having the outer end thereof disposed somewhat lower than the inner open end. The inner end of the reciprocating and oscillating pan D, is supported to swing on the inner swinging supporting arm G. The inner swinging supporting arms G, are of suitable spring material, made fast at their lower ends at g, to opposite sides of the frame A, and at their upper ends are loosely connected to the opposite inner side ends of the pan D, at g whereby the pan is not only supported for a swinging movement, but is also assisted in its reciprocations in one direction by the tension of such spring arms. Theother outer end of the pan D is supported on the upper ends of the swinging operating arms H. The swinging operating arms H, are pivotally mounted at their centers on the drive shaft h, mounted transversely at one end of the frame A and' carrying at opposite ends thereof the pulleys h and h respectively, the former of which receives the belt from the driving power. The upper ends of the arms H, above the shaft h, are pivotally connected to the bottom front end of the pan D, on the rod I, supported in brackets i, beneath said pan, and the lower ends of said arms H, below the shaft, are provided with adjustment perforations 11,

to receive the pin i adjustably connecting the outer end of the pitman, J, thereto. The outer end of the pitman J, is also provided with adjustment perforations j, which together with those of the arms H, provide means whereby the length of reciprocations and oscillations of the pan D, can be regulated as may be required. The inner end of the pitman J, is loosely connected to the central crank of the triple or multiple crank shaft K, journ aled in bearings on intermediate uprights B, and carrying at one end a belt wheel is, which preferably receives its motion from the belt is, passing over the wheel 71,2 and an intermediate belt tightener 70 The bundles which are forced by the reciprocating-oscillatory movement of the pan D, to-

ward the inner end thereof, are forced under a series of band cutting knives L, mounted on a transverse knife shaft Z, journaled in opposite upright extensions B so as'to be arranged over the upper edges of the opposite sides of the pan D, and said knife shaft receives its motion from the belt 70, which passes over one of the pulleys Z, on each end of said knife shaft.

Each of the band cutting knives L, comprises a series of cutting blades M, having rounded sharpened cutting edges adapted to pass through the bands of the bundles of grain, as they are forced thereunder, and arranged between the several knives, and the outer knives and the sides of the pan D, are the intermediate fender strips m. The fender strips m, encircle the exposed portions of the knife shaft between the knives, and are secured at their upper ends to the transverse supporting bar m. The said intermediate fender strips, owing to their disposition, provide efiicient means whereby the strawisprevented from wrapping on the knife shaft. The cutting knives are arranged over the bundle carrying pans so that, after the bands are cut, the movement of the pan distributes the grain evenly across the same before discharging onto the upper ends of the inclined reciprocating notched feed plates N. The said inclined notched feed plates are arranged to receive the discharge from the bundle carrying pan, and are adapted to have their lower ends slide above the upper end of the back rest 77., which when the machine is placed in position is designed to rest against the frame of the separator,which is immediately in front and under the cylinder, so that the lower ends of the feed plates N, will pass over this part of the separator frame, and within a few inches of the cylinder as will be readily understood. The notched feed plates N, are further provided at their adjacent edges with the toothed flanges O, which not only serve to confine the grain onto the plate but also assist in evenly feeding the same to the cylinder of the separator, while the outer edges of the outer feed plates are provided with the upwardly extending sides 0, which hold the grain onto the feed plates and form an inclined chute through which the grain is forced.

To the inner upper ends of the several notched feed plates N are pivotally attached the upper ends of the vibrating rock arms P, pivotally mounted on the stationary rod or shaft ,79, suitably mounted, and provided with lower perforated ends p',to which are adj ustably connected one end of the connecting bars or arms Q. The connecting bars Q, are provided with a series of perforations q, at their ends attached to the arms P, to provide for regulating the movement of the feed plates N, and the other ends of said connecting bars are pivotally attached to the remaining cranks of the triple crank shaft K, except the central connecting bar which is pivotally attached to the inner end of the pitman, J. Now it will be readily seen that as the triple crank shaft K, is put in motion by the means described, the bundle carrying pan D, is given a lifting or oscillating-reciprocatory movement, simulprovided for automatically feeding the bundles to the knives cutting the bands, and

, evenly distributing the grain to the separator. Arranged to vibrate over and partly within the feed chute formed by the inclosed feed plates N, is an upper vibrating feed box R. The upper vibrating feed box R, is provided with the opposite depending sides a", which are adapted to work inside of and above the opposite sides 0, of the outer feed plates N, and also the inner ends of the opposite sides of the pan D, so as to form together with the feed plates, an inclosed chute, which completely confines the grain therein, until it reaches the cylinder of the thrasher, it being readily seen that the upper vibrating feed box R, necessarily, must extend almost to the cylinder cap of the separator to make the space in front of the cylinder an inclosed one. The said box R, is further provided, between the sides thereof, with the notched feed bars 7'', which combine with the feed plates to force the grain into the thrasher cylinder. The outer end of the upper vibrating feed box B, is sup ported on the swinging links S. The swinging links S, are pivotally attached at their lower ends to the box R, near its lower end and are provided at their upper ends with a series of adjustment perforations s, which receive the supporting pins 3, projecting from one end of the opposite inclined frame pieces T, supported on the extension uprights b, and by means of the adjustment of said arms, the space between the feed plates and the upper feed box is regulated to accommodate difierent kinds of grain. The said upper vibrating feed box R, receives its motion from the transverse crank shaft U, j ournaled on the inclined frame pieces T, at u, and carrying a pulley a, at one end, which receives its motion from the belt 11?, passing thereover and one of the pulleysat one end of the knife shaft. It will be apparent that as the crank shaft rotates, the upper feed box R, must necessarily be, given a long swing ITO ing-vibratory movement which greatly aids in the even distribution of the grain to the thrasher.

It is thought that the operation and advantages of the herein described band cutter and feeder will be apparent, and it will of course be understood that changes in the form, pro

portion and the minor details of construction as embraced within the scopeof the appended claims, may be resorted to without departing from the principle or sacrificing any of the ends of said pan and having a vibrating top and bottom, substantially as set forth.
