OLIVER ANDERsoN, or FORT TOTTEN, DAKOTA TERRITORY.

BAND-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 377,975, dated February 14, 1888.

Application filed November 2, 1886. Serial No. 217.824. (No model.)

To all whom it may concern.-

Be it known that I, OLIVER ANDERSON, a citizen of the United States, residing at Fort Totten, in the county of Ramsey and Territory of Dakota, have invent-ed new and useful Improvements in Band-Cutters and Feeders, of which the following is a specification.

My invention relates to band-cutters and feeders to be used in connection with power thrashing-machines.

Thepurpose of my invention is to provide a positive, simple, and'efficient mechanism by which the bands shall be cut with certainty, irrespective of the size of the bundle, and by which the latter shall be held to its place and moved rearward and upward, while the cutters are swept in the opposite direction, or downward and forward, thereby giving a greatly-increased power and certainty to their action.

It is also the purpose of my invention to combine with the feeding devices automatic fingers for controlling or stopping the feed, and which may be easily and quickly adjusted to regulate the volume of straw fed to the thrasher, said fingers being combined with devices whereby they may be raised and lowered, to increase, diminish, or wholly arrest the feed, as circumstances may require.

The invention consists in the several novel features of construction and combinations of parts hereinafter fully set forth, and definitely pointed outin the claims annexed to this specification.

In the accompanying drawings, Figure l is a longitudinal section illustrating my invention. Fig. 2 is aplau view of thesame. Fig. 3 is a detail section enlarged, showing-the construction of the cutters and their relation to the feed apron or table. Fig. 4 is a side elevation illustrating the devices which adjust the feed-fingers toward and from the feedapron.

In the said drawings, the reference-numeral 1 designates the frame-work of the machine, which is mounted upon an axle, 2, located not far from the central portion. This axle is supported in or upon castings 3, which are provided with slots 4, in which are inserted bolts 5, passing into the side pieces of the frame. The purpose of this construction is to l enablethe frame to be raised or lowered,while the wheels rest on the ground.

Near the front end of the frame are pivoted two legs, 6, by which the end may be raised and supported, to give a suitable inclination to the feed apron or table. The axle 2 may be secured at any point within the limit of 4., and may be secured at such point by nuts 7, turning upon the bolts 5.

Upon the framel is supported the feed apron or table 8, which is mounted upon springsupports 9, attached below to the cross-beams 10 on the frame and pivoted above to ears upon the under part of the feed apron or table, said supports being inclined toward the front of the machine, so that at each reciprocation of the feed apron or table it will be thrown rearward and upward and upon the returnstroke downward and forward.

bottom wall having transverse slatsand at intervals transverse combs 12, the teeth of which are inclined toward the delivery end of the apron or table.

The feed movement is imparted to the apron or table by means of a crank-shaft, 13, j ournaled in bearings 14 on the frame 1 and connected with spriug pitmen 15. This crankshaft is moved by a pulley, 16, belted to the power-shaft in any suitable manner.'

Extending longitudinally of the feed apron ion-board, 17 upon which is pivotally-mounted one end ofa pitman, 18, connected at its other the ends of which are mounted in bearings 21, supported by the frame 1. Upon this shaft are mounted the cutters-i-four in number-arranged in such manner that two of said outters lie upon eachside of the division-board 17. Each of these cutters consists of a semicircu lar plate, 22, having its edge provided with cut teeth similar to those of a reaper-sickle section. Each cutter is mounted upon the the cutter-plate being on-the side next the thrasher. Within extensions 23 of the bear ings 21 is journaled a rock-bar, 24, having rods 25 extending toward the front of the machine. These rod's extend nearly to the. delivmovement afforded by the length of the slots rock-shaft eccentrieally, the longer radius of a The feed apron or table comprises a solid or table, near its rear end, is a central divis- I end to a finger, l9, rigid upon a rock-shaft, 20,

ery end of the feed apron or table, at which point they are loosely connected to a transverse supporting-bar, 26, having cranks 27 at its ends, which are supported in bearings 28. Each rod is provided at its extremity with a downwardly-projecting point, 29, which approaches, when at its lowest adjustment, close to the surface of the feed-apron.

At one end the journal of the supportingbar 26 is extended, and an adjusting arm, 30, is rigidly mounted thereon. This arm en-, gages with a segmental rack, 31, upon the frame 1 in such manner that by swinging the arm toward the thrasher the supporting-bar 26 is raised, while by moving it in the opposite direction said bar is lowered until, at its lowest adjustment, the points 29 of the rods 25 are brought down close to the surface of the feed apron or table. By these means the feed may be regulated to any desired degree. The number of rods 25 is preferably eight or ten, though a greater or less number may be used, if required, the number shown in the present case being four.

The operation of the parts thus described is as follows: The crankshaft 13 being set in motion, the feed apron or table is reciprocated toward and from the thrasher, rising somewhat upon the rearward stroke and dropping as it moves forward. At the same time the cutters 22 are rocked by the shaft 20 in a direction opposite to the movement of the feed apron or table, their eccentric position on the shaft causing the segments of greatest diameter to move downward toward the feed apron or table, while at the same time the rotary movement gives a draw out to the edges. In this manner, the apron or table rising toward the cutters as it moves rearward and the cutters turning downward and approaching the apron or table as they move forward, each bundle is acted upon surely and efl'ectually, and the band is severed whether the bundle be of great or small size. The combs 12 are for the purpose of preventing the bundle from moving in a direction away from the thrashingmachine while the bands are being cut. The

feed-points 29 serve to tear matted or tangled straw to pieces.

A tongue, 32, is attached to the rear end of the machine to enable it to be transported upon theroad. \Vhile being moved from place to place the legs 6 may be turned up over the end of the feed-table.

The feeder and band-cutter may be connected to the thrasher by hooks, as shown, or in any other suitable manner.

What I claim is- 1. In a band-cutter and feeder, the combination, with a reciprocating feed-apron, of cutters having a circular edge, a rock-shaft on which said cutters are eccentrically mounted, and means for vibrating said cutters in a direction opposite to the movement of the apron, substantially as described.

2. The combination, with a frame, a feedapron, and forwardly-inclined pivotal supports therefor, of a crank-shaft for vibrating said apron, a rock-shaft journaled above the same and provided with an upwardly-extended arm, and cutters rigidly and eccentrieally mounted upon said rock-shaft, and a pitman connecting the arm on the rock-shaft with the reciprocatingapron,substantially as described.

3. The combination, with a vibrating feedapron, of a roclcshaft, rods secured thereto and having downwardlyextending feed-regulating points, a cranked shaft supporting the said points, an arm rigidly attached to one end of the cranked shaft, and means for adjusting and locking the arm at any point within its are of adjustment, substantially as described.

4. The combination, with a reciprocating feed-apron having transverse combs, of semi circular cutters eccentrically mounted above said apron, a rock-shaft carrying the cutters and having an upwardly-projecting arm, and a pitman attached at one end to the upright arm and at the other end to the feed-apron, whereby the reciprocation of the apron gives the cutters movement in a direction opposite to that of the apron, substantially as described.

5. The combination, with the frame and a rock-bar journaled in bearings thereon, of rods having downwardly-extending feed-regulating points, and having one end supported by said rock-bar, a cranked shaft supporting the other ends of the rods, an arm rigid on one end of the cranked shaft, and a rack by which the arm may be held at any point, substantially as described.

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

OLIVER ANDERSON.
