FEED CUTTER.

SPECIFICATION ionizing part of Letters Patent No. 378,112, dated February 21, 1888.

Application filed December 27,1886. Serial No, (No model.)

To aZZ whom it mcty concern.-

Be it known that I, Ennnnznn \V. RIDER, ofltacinc, in the county of Racine, and in the State of \Visconsin, have invented certain new and useful lm p rovcnients in Feed-Gutters and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to feedcutters; and it consists in certainpeculiarities of construction and combination of parts, to be hereinafter de scribed with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a front elevation of my invention; Fig. 2, a side elevation; Fig. 3, a similar view with the driving-gear removed, and Fig. 4 a detail view of a pawland-ratchet mechanism for actuating the feed-rolls.

Referring by letter to the drawings, A represents the feed-box of my machine, mounted in a suitable frame, said box being provided at its front end with a shear-plate, B, and secured to the frame adjacent to this plate is a knife-guard, O. J'ournaled in suitable bearings so as to operate within the box A are feedrolls D D, of the ordinary construction and adjustment. Fast on the journals (4 a of the feed-rolls D D, at the drive side of the machine, are ratchetwheels E E", and loose on these journals are arms F F, the latter having pivotally connected thereto pivoted springactuated pawls G G, that engage said ratchetwheels.

In Fig. 4 l have shown a detail view of the pawland-ratchet mechanism, and in this instance I employ a spring, I), to keep the pawl G in engagement with the arm F.

If found desirable,the pawl G may be weighted, as shown at 0, Figs. 2 and 3.

To the arms F F, I pivotally connect the forward ends of links H it, that have their rear ends similarly connected to the vertical ears d ol'a rack-plate, l, the latter being operativclyarranged in guides c, suitably secured to the box A.

Theforward end of the rackplatel is turned out at right angles to form an ear, f, and this car has a perforation that serves as a guide for a rod, J, connected with a crank-arm, K, on the inner end of a short shaft, K, operativein a. suitable bearing, 9, secured to an extension of a transverse brace, L, that is in turn fastened to the under side of the box A, said short shaft being provided with a bevel-pinion, M, keyed thereto at its outer end. The rod J is provided with a collar, h, and between this collar and the earf of the rack-plate I is arranged a spiral spring, N, the tension of the latter being regulated by a thumbnut, i, on the forward end of said rod.

Pivotally connected to the adjacent side of the box A is a dog, 0, that serves to engage the rack-plate I at such times as it may be desirable to stop the feed of the rolls D D.

In order to vary the feed of the rolls D D, the crank-arm K is provided with a series of perforations, j, and the throw of the rod J is consequently lengthened or shortened, accord ing to its engagement with said perforations.

Meshing with the bevel-pinion M is a similar pinion, 1?, on the adjacent end ofa crankshaft, Q, that has its bearing is It, respectively, secured to the extension of the "eross'brace L and a standard, L, at the front of the frame. To the crank-portion Qoftheshaft Q is loosely connected one end of a knife, R, that comes across the month of the feed'box A, the opposite end of this knife being also loosely connected to a stud, m, on the lower terminus of a curved lever-arm, S, pivotally secured to a bracket, T, the latter being secured to a front standard, T, of the supporting'fraine and projected over to nearly or quite the transverse center of said box.

The crank-shaft Q has keyed thereto a flywheel, U, and by a suitable construction and arrangement of gearing any desired speed may be given said shaft. In this instance I show a bevel-pinion, V, fast on the shaft Q and arranged to mesh with a bevel gear-wheel, V, journaled in a bearing, X, secured to the extension of the cross-brace L, said wheel being twice the diameter of the intermeshing pinion and having a crank, Y, fast on itsjournal. If found desirable, the speed-gear may be omitted and the crank Y applied to the flywheel U.

A. springarm, Z, has one end thereof rigidly secured to the under side of the brace-piece L and its other end brought over upon a transverse bar, Z, to which latter are adjustably" shown by Fig. 1 when the crank-shaft Q. is operated this knife will be drawn thereby toward the operator, while at the same time the levervarm S operates to drive said knife in the same direction, whereby a double power is exerted to produce an easy, sliding, and shear cut in a direction away from said operator. While the machine is running that end of the knife R nearest the operator describes a circle, 0, as shown by dotted lines, Fig. 1, the other end of said knife traveling on an are, p, of a circle having a larger diameter than the one 0, and also illustrated by dotted lines in the same figure. The knife It begins to out at that side of the box nearest the operator and gradually performs its function as the opposite side of this box is approached, the inclination of this i knife being diminished as the work proceeds until at the time its edge has entirely passed the shear-piate B said knife will be nearly or quite horizontal.

In Fig. 1 is shown by dotted lines the knife in various stages of its descent, and by this illustration it will be noticed that said knife does not come at'any one time on. the whole mass that may protrude from the mouth of the feed-look. The pinion M, meshing with the pinion I? on the crankshaftfimparts motion to the crank-arm K, and this latter part in turn imparts motion to the rod J, that has a loose bearing in the ear f of the rack-plate I. When the dog 0 is clear of the rack-plate I, the latter is actuated by the rod J, and, being linked to the arms F F, causes the pawland-ratchet mechanism,previously described, to partially rotate the feed-rolls D D when the knife R is on. its return after completing acut, thereby bringing more material from the box A into the path of said knife, the length of feed being regulated by the throw of the rod above described.

YVhen it is'desirable to stop the revolution of the feed-rolls, the dog 0 is dropped, and the raolr-plate I is thereby held stationary, the rod J having its play through the perforation in the earf of said plate.

plate, a pinion having its journal provided with a crank-arm, a rod uniting the loose plate with the crank-arm, and a drive'shaft having a pinion arranged to mesh with the one above specified, substantially as and for the purpose set forth.

2. In a feed-cutter, the combination of a box mounted in a frame, feed-rolls operatively arranged in the box and having their journals at one end provided with ratchet-wheels, arms loosely arranged on said journals and carrying pawls to engage the ratchet wheels, a loose rack-plate operatively connected to the adjacent side of said box and united by links with the pawl-arms, a pivoted dog arranged to be brought into engagement with the rack-plate, a pinion having its journal provided with a ciankarm, a rod having a loose bearing in an ear of said rack-plate and connected with the crank-arm, a spring arranged on the rod, and a drive-shafthavinga pinion arranged to mesh with the one above specified, substantially as and for the purpose set forth.

3. In a feedoutter, the combination of a suitable frame, a box mounted in the frame,.

feed-rolls arranged in the box, a transverse knife, a crank-shaft loosely connected to one end of the knife, a leverarm likewise connected to the other end of said knife, ratchetwheels fast on the journals at one end of the feed-rolls, suitable arms loose on said journals and provided with paw-ls to engage the ratchetwheels, a sliding plate connected to said box,

links uniting the pawlarms and plate, a crank arm, a rod uniting the sliding plate and crank arm, and a piniongear connecting said crank arm and crankshaft, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Racine, in the county of Racine and State of Wisconsin, in the presence of two witnesses.
