IMPROVEMENT IN FEED-CUTTERS.

Specification forming part of Letters Patent Nov l 74,235, dated February 29, 1876 application filed January 8,1876.

To all whom it may concern Be it known that I, EDGAR R. HALL, of Waterville, inthe countyof Oneida and State of New York, have invented a new and valuable Improvement in Feed-Cutters andvl do hereby declare that the following is a full, clear, and exact description of the construc- 'tion and operation of the same, referencebeing hady to the annexed drawings, making a v part of this specicatiom and to the letters and figures-of 4reference marked thereon.

4Figure l of the drawings is a representa tion of a longitudinal vertical section of `my feed-cutter, and Fig. 2 is a transverse vertical sectional view of the same. Fig. 3 is a sectional detail view thereof.

My invention relates to machines forcutting hay, straw, or corn-stalks for feed; and itconsistsinthe construction and general arrangement of" a horizontally-runningknife with vibrating apron upon which the'feed is broughtto the knife, the feed-rollers of the machine geared by a rubberjband; in the ratchet-device for operating the feed-rollers 5 and in the combination of parts as willV be hereinafter more fully set forth.

In the annexedV drawings,- A represents the' feed-box, supported upon a suitable frame, B,

and formed with a throat, (l, through which the feed passes to the feed-rollers D D.

In front ofthe feed-rollers is hinged an apron, E, forming a continuation of the bottom of the feed-box. Ou this apron is erected, as it were, a tapering box, H, open at both front andrear, and providedin the top with a 4hinged leaf, I, pivoted at its rear end and pressed downward at the front by a spring, a, so as to hold the feed down on the apron E, close to the point where it is cut by the knife Across the front end of the apron E, in

V)the upper side, is a groove, b, for fheknife to work in. This knife is attached to a diamondshaped bar, K, which runs in correspondinglyshaped guides in the sides of/the box at' the frontend, the knife passing/through slots in the sides of the box.

The knife runs horizontally, and is operated by the following means: From the center of' the bar K projects a vertical stud or pin, d

on which is placed one end of a pitman, L:

the other end thereof' being placed on a crank or wrist-pin, e, on a wheel, M, secured on the upper end of a shaft, N,said shaft having its bearings in a frame, O, secured to the side of the frame B at the front end.

0n the lower end of the shaft Nis a beveled gear-wheel, f, which gears with a bevel cogwheel, P, on the end of the main shaft R. This shaft has its beari-ngs in the main frame B, and is on ifs other end provided with a pinion, h, which gears with the cogged crank-- wheel S, said. wheel bein gmounted on a stud projecting from the frame B, as shown.

On the center of the main shaft R is an eccentric, i, around which is placed an arm,

' T, connecting with the hinged apron E.

At theslde of the cog-wheel P, ,on the main the other end of 'said shaft, next Ato the pin-` ion h,is an eccentric, m, connectedbya pitman. Y, with a slotted lever, Z, placed loosely on the journal of the lower feed-roller D. On said journal is secured a ratchet-wheel, p, into which takes a spriug-pawl, s, pivoted to the lever Z.` `As the shaft R revolves this lever and its pawl are moved so as to, atthe proper time, revolve thesaid lower feed-roller, it be- Y ing held from turning backward by means of another spring-pawl,""t.- By changing the point of connection"between/the ppereietdi the pitlnan Y and the lever Z closer to or farther 'f'rom the pawl s, the extent of' the feedmotion is easily regulated so "as to cut the feedV longer or shorter, as desired.

The journals ofthe upper feed-roller D are placed in vertical slots in the sides ofthe box, and on thejournals ofthe two rollers are pulleys w connected by means of a rubberwbelt, m, which allows the rollers to adjust themselves to the feed as it is placed within reach of said rollers.

The operation of themac'hine is substantially as follows: l

The hay, straw,'"&c'.,isfed in by hand in the usual manner until it is caught by the feed rollers, when they draw it forward to the desired length, according as the feed mechanism has been set. It is thereby passed forward between the apron E and pressure-board vAssojon as the/feed stops, the eccentric i forminga continuationof the hottomuof the -feed-box, provided with thel hinged leaf I pivoted at its rear end and pressed downward at the front-by a spring, a, in combination with suitable operating mechanism, substantially as and forthe purpose set forth,

In testimony thatl claimtheabove, I have hereunto subscribed my name in the presence of two witnesses.

f EDGAR R. HALL.

and pitman T raise the apron Eupward,carL rying the straw up to the knife'J,which is continually reciprocating horizontally in its guides. When the straw has thus been cut, the apron E descends again and the feed mechanism turns the r llersr-tol feedthe straw forward again.

The knife J may either have a straight cutting edgeor a sickle-shaped edge, as desired, or deemed most advantageous.

What I claim as new, and desire to sfcure by Letters Patent, is

The hinged vertically-vibrating: apron E.
