SPECIFICATION forming partof Letters Patent No. 292,182, dated (January 22, 1884.

Application tiled July To all whom it may concern:

Be it known that I, CLARENCE CHRISTIAN SMALLEY, a citizen of the United States, residing at Manitowoc, in `the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Feed- Gutters; and 'I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed and to the letters and figures' of reference marked thereon.

Figure l of the drawings is a perspective view of a feed-cutter constructed in accordance with my invention; Fig. 2, a side elevation, in detail and on an enlarged Scale, showing the gearing 5 Fig. 3, a top plan view, partly in section, Fig. 4, a side elevation ofthe feedcutter, partly in longitudinal Section; Fig. 5, a cross-section, Showing the position of the throat and cutting-plates upon the machine; Fig. 6, a detail view, in perspective, of the throat and cutting-plates. y

rlhe present invention has relation to certainnew and useful improvements in feedcutters, and has for its object to improve and simplify the several operating parts, whereby the length of the out may be more readilyr changed and the general operation of the machine rendered more practical and effective, and less liable to become inoperative. These objects I attain by the construction substantially as shown in the drawings, and hereinafter describedand claimed.

In the accompanying drawings, A represents a suitable frame, to which is connected the usual feed-box, B, and chute @also the several operating parts of the machine,liere inafter described.

The cutting-knivesD are suitably attached to heads or arms a upon a horizontal shaft, E, said knives being vlocated between plates b, over which closes a cover, F. The shaft E has its bearings in suitable boxes, c, connected to the frame of the machine, and has attached by key or otherwise a pini n, d, which meshes with a pinion, e, said pinion\running loosely on a stud, f, held stationary bybeing screwed into one of the side plates, 1)and` supported passes and revolves. The pinion e has twice i9, 183. No model.)

the toothed circumference of pinion d, and meshes with the pinion G of a double pinion, G'h, said doublepinion revolving loosely upon a stud, z'. The bearing of the stud z' has a surface twice the length of the hub of the double pinion and the same length of the stud f, on which the wide pinion e runs, the stud being firmly fastened to a lever, H, by means of a n ut on inside of lever, and supported and held to its relative distance from the stud-f by a brace, k.

Upon the stud i. is Fig. 3, said collar. having the same length as the hub of the double pinion, and removable from the stud for the purpose hereinafter described. The lever H is bored to Slip on the stud f, upon which the wide pinion e revolves, andvthen extends back and carries, as hereinbefore described, the double pinion G h, said lever passing through anotched quadrant, K. The lever H is provided with a suitable handle, to which is attached a'spring-clutch, L, of the ordinary construction, Said Aclutch engagin g with the notches on the quadrant. The pinion h of the double pinion G h meshes with a large Spur-wheel, M, which is secured to the shaft of the lower feed-roller, N, the opposite end ofthe shaft having a gear-wheel, Z, which qmeshes with a similar wheel, m, upon the shaft yof the upper feed-roller, O, said roller being a collar, I, as shown in made yielding in its bearing by springs n of rubber, or by any other suitable means found desirable. The pinion d on driving-shaft E meshing with the pinion e, motion will be iinparted to the latter, and it, meshing with pinion G of the double pinion G 7L, will in turn -be driven, as will also spur-wheel M in like manner, thus V.transmitting the power from driving-Shaft to feed-rollers by means ofthe gear-wheels Z m upon theshafts thereof. Now, when the lever H is lowered to a certain point, or in the lower notch-of the quadrant K, the larger pinion G of the double pinion will be in mesh with the wide pinion e,jand the smaller pinion 7L of said double pinion will be in mesh with the spur-wheel M, thereby producing the required. speed on the feed-rollersnecessary to make a short cut on the hay or other product passing between therollers. Vhile running' in this position, by raising the lever H to the second notch in quadrant K or higher, the

IOO

` erture in the plate tothe knives.

pinion h of the double pinion is a-t once thrown out of mesh with spur-wheel M, and the feedrollers stopped thereby, thus avoiding aceident or breakage should any obstruction get between the rollers or should the operator become caught in the machinery. For changing the length of the cut, lever H is raised to the upper notch in the quadrant K, and the brace l.: removed by irst removing the nuts, after which the collar I and the double pinion G h, can be slipped off from stud fi. The collar is now replaced on the stud, and afterward the double pinion, but being reversed, and the brace is fastened, and when the lever is lowered to middle notch of quadrant, or to the required point, the large pinion G of double pinion will mesh with spur-wheel M, and also with wide pinion e, thus giving a faster speed to the feed-rollers and making a long cut of feed, and while the pinions are in this position, by raising the lever to the upper notch in quadrant, the double pinion, as above described, is thrown out of gear with the spurwheel, and the rollers stopped to avoid accident or breakage, as hereinbefore described.

The ily-wheel P has an internal tapering hub, o, which iits over a eorrespondingly-ta-- pering end, p, of the shaft E, and the extremity of the tapering end has a left-hand thread cut thereon to receive a screw-nut, q, said nut being prevented from working off by a split key or other device entering a hole in the screwthreaded portion of shaft. The taper on shaft is such that when fly wheel is pushed on the hub of said wheel comes over the threaded portion of shaft perfectly flush, after which the nut is screwed .on until the inside face comes in contact with the hub and the fastening device inserted. Now, when the machine is in operation, should the cutting-knives on shaft meet with any obstruction, as is often the case, the sudden jar to the fly-wheel would immediately loosen the nut, and the -wheel would then revolve loosely upon the shaft, while the split key or other fastening device would prevent the nut and consequently the wheel from working off.

In Figs. 5 and 6, R represents what I term a throat-plate, located between the cuttingknives and the feed-rollers, said plate having lugs 1', by means of which it is bolted in an upright position to the frame of the machine, between the side plates hereinbefore described, the material to be cut passing through the ap- The bottom of the throat-plate R is cored out so as to admit of a thin plate of steel, which I term a cuttingplate,7 S, being fastened to the throatplate by suitable bolts, s, passing through elongated slots t in the cutting-plate, to admit of its adjustability to or from the feed-rollers or cutting-knives. The throat-plate R is cast with a support, s', upon which rests the cutting-plate S, and through which pass the bolts s, said throat-plate being also cast with upright flanges t t t t. These anges are arranged in pairs at each end of the throat-plate, and a suitable distance apart to admit between them tapering keys u, the anges forming guides for the upright keys and holding them in position, while the lower end of the flanges form stops, against which abut the ends of the cutting-plate S, as clearly shown in Fig. 6. Vhen the bolts s are loosened, by driving down the taperingwedges or keys a it will bring the plate S in contact with the knives D, and it can be accurately and easily adjusted as required. rlhe plate S may be hardened, thus giving a hard surfacel for the knives to cut against, this being of great advantage in saving of wear on plate.

To the lower part of the frame A of the machine is bolted a supplemental frame, consisting of two side bars, 0, connected a little distance from their rear ends by two crossbars, w. In bearings attached to the side bars, o, revolves a shaft, V, to which is attached a small bevel-gear wheel, XV, the teeth of which mesh with those of alarger and similar wheel, X, attached to a shaft, J, which revolves in bearings connected to the cross-bars w, and n has a connection, y, formed on or attached to its rea-r end to receive the end of a tumblingrod of a horse-power. The gear-wheels may differ more or less in size as the speed of the horse-power by which the feed-cutter is to be driven may require; or the gear-wheels may be made with straight teeth, the shafts being placed parallel with each other, and the connection y projecting at the side of the feedcutter, according as the construction and speed of the horse-power by which the said feedcutter is to be driven may require. To the end of the shaft V is attached a pulley, U, to receive a belt which also passes around a pulley, T, upon one end of the driving-shaft E. "With this construction the feed-cutter can be provided at the factory with a power attachment consisting of the supplemental frame, shafts, gear-wheels, and pulley, which can be readily and quickly connected to the frame of the machine to drive the feed-cutter at the required speed, as the particular horse-power that is to drive it is known, so that the buyer will have nothing to do but apply the tumbling-rod of his horse-power to the connection at the extremity of one of the shafts.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a feed-cutter, the combination, with a wide pinion adapted to be rotated upon a fixed stud, and a spur-wheel secured to the shaft of the lower feed-roller, of a removable and reversible double-pinion mounted upon a IOO IIO

stud, said stud being twice the length of the hub of the double pinion, and having a removable collar thereon, and also having removably connected to its outer end a suitable brace to retain the double pinion and collar in position upon the shaft, substantially as and for the purpose set forth.

2. In a feed-cutter, a rotary shaft, carrying the cutter-knives and a pinion, and having loosely mounted thereon a supporting-brace and a wide pinion adapted to revolve upon a stud attached to said brace and one of the side plates of the machine, in combination with a removable and reversible vdouble pinion` mounted upon astud projecting from a hand-lever, said stud having a bearing-surface twice the length of the double pinion, and provided with a removable collar adapted to slip over the stud to hold said pinion in a reversed position upon either end thereof, for the purpose specified.

3. In a ieedcutter,a notched quadrant, a pivoted hand-lever, and means for holding it in an adjusted position, in combination with a removable and reversible double pinion supported upon a stud projecting from the side of the lever, said stud being twice the length of the hub of the double pinion, and having thereon a removable collar, and connected at its out-er end by a suitable brace to a similar or tapering keys located between the flanges of each pair as a means I "vor adjusting and holding the cutter-plate in the position desired, substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my naine in the presence of-two witnesses. j
