BAN D-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No; 531,541, dated December 25, 1894.

Application filed July 17, 1894.

To aZZ whom it may concern.-

Be it known that I, FRANK F. LANDIS, a citizen of the United States, residing at W ayn esborough, in the county of Franklin andjState of Pennsylvania, have invented certain new 7 and useful Improvements in Band-Cutters and Feeders; and I do hereby 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.

This invention relates to band cutters and feeders used in connection with thrashing machines; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings: Figure 1 is a side view of the device, showing the hopper in section. Fig. 2 is a plan view of the device. a cross section taken on the line was in Fig. 2. Fig. 4. is a vertical section taken on line y y in Fig. 2.

A is a portion of the frame of a thrashing machine; A is the thrashing cylinder and a is the concave. These parts may be of any approvedconstruction.

The band cutter and feeder is attached to the frame A in front of the thrashing cylinder.

B is the hopper for receiving the unthrashed grain.

B is a guard plate provided with slots b.

O is a packing roller mounted on the shaft 0 and journaled in the hopper B longitudinally of the thrashing machine. The roller 0 is provided with teeth 0 which project through "the slots 1). The upper part of the guard plate is inclined, and its lower part is curved, and a space suflicient for a sheaf to pass through is left between the bottom of the guard plate and the bottom of the hopper. D is the packing chamber arranged on one side of the hopper B and between the side portions of the frame A. The packing chamber is of about the same length as the roller 0, and is provided with an inclined bottom D joining onto the bottom of the hopper B.

E is the breast board at the front of the packingchamber, and E is an inclined guide plate extending from the top of the breast board to the concave.

F is the feed roller journaled in bearings Fig.3 is

' the" thrashing cylinder.

SerialNo. 517.773. (No1nodel.)

G" 's a cover wh'ch is secured to the frame A over the feed roller. This cover is preferably provided with a curved portion g over the feed roller, and a second curved portion g over the guide plate, E.

Rotary motion is communicated tot he packing and feed rollers by any approved driving mechanism. The feed roller may conveniently be revolved by the belt pulley h secured on the shaft F.

. His the drivingbelt' which passes around the belt pulley h on the end of the shaft of The belt H is arranged to bear on the pulley h and to revolve it.

The packing rollermay have a beveled toothedwheelt' secured on the end of its shaft 7 O for the purpose of revolving it.

I.is a beveled toothed Wheel journaled'on the pin 1'. which projects from the frame A.

The wheels I and 1" gear together.

J is a belt pulley secured to the wheell, and

j is a belt pulley secured on the end of the shaft of the thrashing cylinder.

K are one or more knives secured to the end of the feed roller next to the packing roller.

L is the chamber under the curved portion g of the cover G.

The operation of the device is as follows: I The unthrashed grain, whether in sheaf or otherwise, is dropped into the hopper B, and

is caught by the teeth of the packing roller 0 and forced under the bottom of the guard plate. The grain is forcedup the inclined bottom of the packing chamber, from below,

against the top board and against the feed roller. The binding twine is severed by one 5 of the knives K as the grain-passes into the packing chamber. The packing roller is caused to revolve at a speed which will compress into the packing chamber in a given time the exact quantity of unthrashed grain which I00 the machine is best suited to thrash during that time. The packing-roller presses the The axis of the, feed 55 loose bundles of unthrashed grain laterally of the straw stalks and forms them into a compact mass inside the packing chamber. This mass of grain is of substantially equal density throughout and extends the full width of the frame. As the said mass of grain moves upward upon the inclined bottom of the packing chamber, portions of it project above the breast board. The revolving feed cylinder picks up the grain from the top of the mass and throws it forward into the chamber L, whence it falls into the thrashing cylinder. The feed cylinder is revolved at a high speed and removes the packed unthrashed grain from the top of the mass in thin layers, and feeds it forward, longitudinally of the straw stalks, without decreasing the density of the lower portions of the packed mass. The feed of grain from the packing cylinder to the thrashing cylinder is uniform in quantity and density irrespective of irregularity in feeding the grain into the hopper, and the thrashing ma chine can therefore be worked up to its full capacity without danger of being overloaded. Then too much grain is placed in the hopper and the maximum density in the packing cylinder is attained, the packing roller slips upon the grain and does not force more of it into the packing chamber until the feed roller has made room for it.

\Vhat I claim is- 1. The method of feeding unthrashed grain to a thrashing machine, which consists in pressing the bundles of loose grain, laterally of the straw stalks, until they form a compressed mass of substantially-uniform density throughout; and then feeding the grain uniformly from the said mass, in thin layers, and in line with the straw stalks, substantially as set forth.

2. The method of feeding unthrashed grain toa thrashing machine, which consists in packing the loose grain into an upwardly moving mass of uniform density,and feeding the grain from the upper surface of the said mass to the thrashing machine in uniform quantity, substantially as set forth.

3. The combination, with a hopper for receiving unthrashed grain, and a packing chamber communicating therewith; of packing mechanism operating to press the loose grain laterally into the said chamber, and feeding devices arranged at right angles to the packing mechanism and operating to feed the grain longitudinally from the packed mass to the thrashing machine in uniform quantity, substantially as set forth.

4. The combination, with a hopper for receiving unthrashed grain, and a packing chamber communicating therewith; of a revoluble packing roller in the said hopper operating to press the loose grain into the lower part of the said chamber, and a revoluble feeding roller arranged above the said chamber and operating to feed the upper layer of packed grain to the thrashing machine, substantially as set forth.

5. The combination, with a hopper for re ceivin g unthrashed grain, and a packing chamber joining onto the bottom of the hopper on one side and provided with an upwardly inclined bottom; of a revoluble packing roller in the said hopper, and a revoluble feeding roller arranged above the said chamber, substantially as set forth.

6. The combination, with the hopper for receiving the unthrashed grain, and the packing chamber communicating therewith; of a revoluble feed roller arranged above the said chamber and operating to feed the upper layer of packed grain to the thrashing machine; the gnard plate provided with slots and secured in the said hopper, and the revoluble packing roller provided with teeth projecting through the said slots and operating to pack the grain into the said chamber, substantially as set forth.

7 The combination, with the packing chamber provided with an inclined bottom, and means for packing the unthrashed grain therein; of a substantially vertical breast board at the rear end of the said chamber, a substantially horizontal top board at the front of the said chamber, and a revoluble feed roller above the said chamber and between the breast board and the top board, substantially as set forth.

8. The combination, with the hopper, and the packing roller journaled therein; of the packing chamber communicating with the said hopper; and the feed roller journaled above the said packing chamber at right angles to the feeding roller and at about the middle of its length, said feed roller being provided with a projecting knife for cutting the binding twine at the entrance to the said chamber, substantially as set forth.

9. The combination, with a thrashing cylinder, of a hopper for receiving unthrashed grain, a packing roller in the said hopper, driving mechanism operatively connecting the said cylinder and roller, a packing chamber joined onto the bottom of the said hopper, a feed roller arranged over the said chamber parallel with the thrashing cylinder and at right angles to the packing roller, and means for revolving the said cylinder and feed roller, arranged at the opposite end of the cylinder from the aforesaid driving mechanism, substantially as set forth.

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

FRANK F. LANDIS.
