BAND-CUTTER AN D FEEDER FOR TH RASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 496,764, dated May 2, 1893.

Application filed November 3, 1892. Serial No. 450,862- (No model.)

-useful Improvements in Band-Cutters and Feeders for Thrashing-Machines; and I do hereby declare the following to be afull, 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 drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in band cutters and feeders for thrashing machines.

The object of the inventionis to provide a band cutter and feeder of improved construction by means of which the sheaves will be fed beneath band cutting knives and therefrom to the feeding board, said feeding board having devices for separating the straw and feeding it to the cylinder of the thrasher; and the invention consists in the construction and combination of the parts, as will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification: Figure 1 is a sectional View of a band cutter and feeder constructed in accordance with my invention. Fig. 2 is a rear elevation. Fig. 3 is a detail perspective view, partly in section. Fig. 4 is a view of one of the agitating fingers detached. Fig. 5 is a detail perspective view, showing the arrangement of the rear set of forks.

The supporting frame of the machine is made up of sect-ions of tubing which are coupled to each other by the ordinary pipe couplings as shown. This form of construction provides a cheap and efficient frame, the parts of which can be readily separated when desired.

a a designate parallel bars or tubes, between each pair of which is bolted a block or hearing for a horizontal shaft b, said shaft having mounted thereon a series of disks B, to which are riveted knives or cutters b-preferably the cutters of a sickle-bar, with serrated edges. A drive-pulley is keyed on one end of this shaft for rotating the same.

0 designates a short section of a bar or tube which passes through couplings attached to the upper ends of the vertical tubes at a and is further braced by a rod 0. A bar or tube 0 is attached as shown and described to the upper end of each pair of vertical tubes at a, and at the outer ends of these horizontal bars or tubes are coupled and braced upright bars or tubes (1 (1. Near the upper ends of these uprights is attached a crossbar or shaft d upon which are mounted suitable blocks e e having rectangular apertures to receive the upper ends of the forks E. Below the center of these forks and rigidly secu red thereto are blocks f, which are also attached to the bent or crank portions of a horizontal shaft F which is mounted in bearings secured to the uprights (1 d. At one end of this crank-shaft is a pulley over which passes a belt for rotating the same.

Between the uprights a a'and below the bearings for the shaft 17 are rigidly bolted plates or castings g provided with hooks g which receive stub-shafts attached to and supporting the rear end of the frame of the carrier belt G.

H designates the front transverse bar or tube of the frame, said bar having rigidly attached thereto depending blocksh with apertures through which pass the ends of support-' ing arms h attached to the forward or highest end of the feed-board. The rear or lower end of this feed-board is provided with a depending apertured block or guide which slides upon an arm 6 secured to the inclined bar or tube I of the frame. These guides and arms permit a longitudinal reciprocation of the feed-board, such a movement being imparted by a pitman-rod K, one end of which is suitably connected to the feed-board while the other end is attached to a crank-shaft journaled in bearings depending from the bars or tubes I; a pulley being keyed on one end of the shaft over which a belt passes for rotating the shaft.

L L designate agitating fingers, which are bent as shown in Fig. 4, the portion Z of each being located in apertures in the cross-piece j or steps located between the upper and lower sections of the feed-board, while the crankshaped ends are located beneath the feedboard and are connected to each other by a bar L'. When this bar is reciprocated the fingers L will be shifted from side to side to agitate or separate the straw. The movement of this bar is attained by means of flexible connections which are attached to each end of the bar and pass around guide pulleys to a stationary part of the frame where they are secured; one of said flexible connections being attached to the frame in front of the bar L while the other is attached to the frame in V the rear of said bar, so that when the feedboard is reciprocated the flexible connections will be alternately drawn upon to actuate the agitating fingers.

M M designate the rear forks, which are attached to the crank-portions m of the shaft m, the upper ends of said forks being guided in blocks mounted on a cross-bar or shaft secured in a slot in the upper end of the standard N, said cross-bar or shaft being adj ustable to and from the crank-shaft so that the throw of the forks can be varied. The frame carrying the rear forks can be readily removed when these forks are not needed.

In the operation the sheaves are fed to the carrier belt and are moved under the knives by the forks E so as to out the bands, after which they fall upon the upper section of the feed-board and move downward between the oscillating fingers L which separate the straw so that it will be loosely fed to the cylinder of the thrashing machine, the movement of the straw beyond the fingers being caused by the vibration of the feeding-board assisted by the forks M.

The feeding devicehereinbefore described is simple and is not liable to get out of order, and it will be noted that the vibration of the feeding-board imparts an oscillating movement to the agitating fingers.

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

1. In a band cutter and feeder for thrashing machines, the combination of a shaft carrying a transverse series of disks or plates between each pair of which are secured sickleteeth and an endless carrier located beneath the same, substantially as shown, and for the purpose set forth.

2. In a band cutter and feeder for thrashing machines, the combination of aband outter, a reciprocating feeding-board, separating or agitating fingers journaled so as to pass through the feeding-board, the ends of the fingers being connected to a bar, and flexible connections passing over guide pulleys carried by the feeding board, the flexible connections being attached to the frame for reciprocating the bar so as to impart an oscillating movement to the fingers, substantially as shown, and for the purpose set forth.

3. In a feeder for thrashing machines, the combination of an inclined feeding-table suitably supported and provided with means for imparting a reciprocating motion thereto, fingers L journaled in a step or cross-bar forming a part of the feeding-table, the ends of the fingers below the feed table being bent to form crank portions which are connected to a 1 transverse bar, flexible connections suitably the bar attached to the fingers will be actuated, substantially as shown and'set forth.

the guide pulleys, substantially as shown, and

for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
