Leners Patent No. 110,834, una January 1o, 187.1

iMPRovEMENT INY'FEED-curTERs.

' Trie Scheduler-eterna td these Letters Patent and making part of the same.

'.lhe object of my invention is to furnish a com. v plete and durable machine capable of cutting-feed of all kinds, hay, straw, corn andother forage, of any desired length within practical limits.

1t has several novel and important -features, one being the complete feeding-device, which is' so arranged as` to cnt coarse' or line at pleasure.

Another feature consists in the device by which the forage is held firmly down while the-'cut is being made, but still allows it to be fed to the knife at the proper time.

Let A, in the drawing, represent the box of the cutter, supported on legs in the usual manner.

Supports a a, projecting from the box A, furnish bearings for a shaft, b,v which carries a heavy crankwheel, on its outer end, secured firmly thereto.

This shaft is bent between its journals to form a `crank, c, and is connected to a cross-beam, d, by

means of a pitman, c.

The beam d is pivotedat one end to a leg of the machine, and receives a vertical reciprocating motion from the pitman e (attached at the other endlwhen the shaft b is rotated. Toothed rollers, C C', form the principal part of the feeding' device.

The lower stationary roller C has V-shaped teeth,

and the upper adjustable roller C has ratchet-teeth.

These rollers are operated by means of ratchetwheels, D D', which are scoured to the outer end of the journals of said rollers. Y

Pawls E P' connected with a bellcrank,1i,mesh with the said ratchet-wheels.

The bell-crank turns or oscillates on a journal, f, secured to, and` projecting from the side of the box A, and receives motionl through the medium of the lever G, which is connected with the beam d by a rod, h. s

It will be seen that by this arrangement a rotary motion is imparted to the rollers O O by the reciprocating motion of the beam (l. The upper roller G' has a vertical play up and down to .accommodate different thicknesses of feed.

The journals pass through slots, i e', lsee' g. 2, in the sides of the box and tum in hangers jj.

These hangers are connectedbelow bya bar, whic passes through a weighted lever, H, substantially as shown. This weight is intended to keep the upper feedroller down firmly upon the forage that is'being cut.

To the crank-wheel B is secured the cutting-knife I, Awhich is attached to one of the arms by means of bolts and nuts, as indicated by 7c k.

. The knife is clearly shown in tig. 3.

A presser, K, connected byhangers,'m m, with a.-

cros's-piece, L, has a guide-rod, 12 and is moved up and-down at each revolution of the wheel B by the' beamd, which has an adjustable connection with the cross-piece L, by the rod o and double nuts, p. This .arrangement is shown in fig; 2.

The machine maybe adjusted to cut long or short by means of a device consistingof a guide-link, fr, in which the lever G reciprocates.

This link has threaded holes, s s, asl shown in iig. 1, in which the thumb-screw U is inserted.

\The height at which said screw is inserted regulates the length of the forage cut by allowing the i pawls E E to pass over a greater or lesserl number of teeth in the ratchets D D on the feed-rollers at each revolution.

The cutting is donc by rcvolving'the wheel'B, to which the knife I is secured, each revolution making one cut.

:The wheel'B ,should be so set upon the shaft b with relation to the crank c that the presser K, will be down at the time the knifeis cutting.l

Having thus described my invention,

A feed-cutter, consisting of the adjustable intermit-' tent feeding device shown, the presser-K; knife-bearing wheel B, and box A, all combined and arrangedx to operate togetherin the manner-shown and for 'the purposes set forth.
