FEED-CUTTER.

SPECIFICATION forming part of Letters Patent No. 345,078, dated July 6, 1886.

Application filed January 18, 1886. Serial No. 188,845. (No model.)

T0 all whom t may concern:

Be it known that we, CHARLES SILBER- ZAHN and CHARLES A. SILBERZAHN, of West Bend, in the county of Washington, and in the State of Wisconsin, have invented certain new and useful Improvementsin Feed-Cutters; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to feed-cutters; and it consists of certain peculiarities of construction, as will be fully described hereinafter with reference to the accompanying drawings, in Which- Figure lA is a side elevation of a portion of a feed-cutter embodying our invention; Fig. 2, a top plan View; Fig. 3, a detail showing the geai` and a portion of the feed-rolls in front elevation; Fig. 4, a detail view of the shifting-frame, and Fig. 5 a detail view illustrat` ing the construction ofthe shaft for the clutchpinion and gear-wheel.

A represents the front standard, and B one of the side pieces of a supporting-frame for the feed-box C andl operating mechanism of the machine. J ournaled in suitable bearings, a, is a shaft, D, having` secured thereto heads b, for the knives c, the end of this shaft on one side of the machine being provided with a pinion, E, and adapted to receive a crank, and to the other end of said shaft is intended to be keyed a flywheel provided with a bandpulley, for connecting the operative mechanism with a suitable driving-power.

F F are the feeding-rollers, of the usual construction and adjustment with relation to the feed-box and knives. The journal of the upper roller, F, has keyed thereto a gearwheel, G, which meshes with a loose pinion, H, journaled upon a short shaft, f, extending outpfrom the cutter-box on the crank side of the machine. Journaled to the cutter-box immediately below the pinion H and meshing therewith is another loose' pinion, I, which also meshes with a gear-wheel, K, keyed to the journal h of the lower feeding-roll, F. This journal h is also designed to receive the sleeve i of an angle-arm, L, said arm having its forward or free end operating in a guidebracket, 7c, secured to the side piece, B, of the 5o supporting-frame. The rear end of the arm L is provided with an inwardly-projecting stud, m, designed to'engage an arch-shaped slot, n, in the lower or segment portion of av lever, M. This lever is pivotally connected to a vertical bracket, O, the latter being secured to the side piece, B, of the supportingframe, and the slot in said lever is provided with sockets `o o at its extremities, adapted to receive the stud m and limit the movement of the arm L in either a forward or'backward direction. To the lower feed-roll journal, h, is also fitted the front end of a straight arm, P, having its other end socketed in flanges p p on the respective rear portions of the arm L, and a triangular arm or plate, R, said parts L, P, and Rbeing united by a bolt, 1', to form Ia frame, though, if found more desirable, these parts may-constitute a single casting. The triangular plate or arm R carries a pinion, S, which meshes with a gear-wheel, T, having its shaft composed of a bolt, s, carrying a sleeve, t, said bolt being adjustable in curved slots u u', respectively formed in the parts .L R, and the sleeve adapted to fit the bore of the gear-wheels hub; rlhis gearwheel T has the inner end of its hub formed with recesses o, adapted to engage projections o upon the outer face of a removable pinion, V, adapted to t upon the sleeve t of shaft of said gear-wheel.

In order to permit of the machine being geared to vary speed, two or more sizes ot" the pinion Vare designed to accompany each cutter, the slots u u in the parts L R permitting the shaft designed to carry one of these pinions and the gear-wheel T to be adjusted so said pinion may be brought into mesh with the gear-wheel K, keyed to the journal of the lower feeding-roll, F.

The above-,described series of pinions and wheels form the entire gearing forour cutter, and are operatively arranged with relation Yto each other upon a single side of the machine, this being considered of material advantage in the matter of compactness and convenience.

When the lever M is in the position illustrated by Fig. l, the machine is out of gear, though the knives may be revolved while the feeding-rolls remain stationary.

It will be noticed that the frame, composedA IOO of the parts L P R, is entirely supported at but two points, said points being the journal h of the lower feed-roll, F, and the arcshaped slot 'n in the segment end ofthe lever M. The frame being thus virtually on a pivot can be readily shifted at the will of the operator. being pivoted on'the journal h,`by moving the upper end of the lever forward the frame is tilted on its pivot, (the journal In) and the pinion S is caused to mesh with pinion E, and pinion V with gear-wheel K. The pinion S being always in mesh with the gear-wheel T, motion is imparted to the lower'feeding-roll, F', through the medium of the pinion V, having a clutch-connection with said gear-'wheel T, and meshing with a similar wheel, K, on the journal of the said lower` roll. This gearwheel K meshes with the pinion Ljournale'd to the cutter-box, and said pinion with another one, H, also j ournaled to the cutter-box, which in its turn comes into mesh wit-h the gear-wheel G on the upper feed-roll, F. The machine is now in gear for cutting feed,which latter is carried from the boxV C to the knives c by the movement of the rolls F F', and to retain the several parts in relation-to each other when the lever is operated to bring them in operative contact, as above described, the stud m on the angle-arm L enters the socket o at the forward extremity of the slot a of said lever,y and by this engagement the stud is not liable t0` become disengaged from its corresponding socket Aunless the lever is forcibly operated, upon. To reverse the action of the feed-rolls F F', the operator throws back the lever uM,v thereby causing an upward movement of the pivotal frame to throw the pinion S out of gear with the one E on the knife-shaft D, and bringing the gear-wheel T into mesh with said pinion E. As this movement' is accomplishedthe stud m of the angle-arm L locks lin the socket o of the arc-shaped slot in the lever. The pinion S, though meshing with the gearwheel T, runs idle when the lever is reversed, while theother pnions and gears remain in the same position as when the machine is feeding .to the knives, their position being unchanged, no lmatter what may be fthe move-vv ment of the shifting-lever and pivotal frame.1

By the construction and arrangement of the gearing and the shifting mechanism, as above described, the feeding-rollers Ycan be instantly reversed or stopped by a single jerk of the lever while the knives are in`full motion, there being no springs or locking devices to raise before said lever can be moved.

The above feature is deemed of particular advantage in case anything of a damaging character should get into the machine. Another advantage lies in the fact that the rollers can be stopped while getting up motion of the knives,` and the faster said knives run the easier the several parts'w-ill gear when the shifting-lever is operated.

The framev slot and a stud, the latter engaging a suitably- `slotted lever, a straight arm connected to said journal, and a triangular arm or plate carrying a pinion and gear-wheel and provided with'a curved slot to register with the one in the angle-arm, substantially as and for the purpose set forth.

2. In a feed-cutter, a pivotally-connected shifting-lever having its lower portion in the form of a segment and provided with an arc shaped slot, in combination with a pivoted frame connected with said lever and provided with a pinion and gear-wheel to be thrown in and out of gear witha pinion on the knifeshaft of said feed-cutter, substantially as and for the purpose iset forth.

3. In a feed-cutter, the combination of suitable gear-fwheels respectively keyed to the journals of the upper and lower feed-rolls, loose pinions journaled on short shaftsA projecting from one side of the cutter-box, and a ment and provided with an arc-shaped slot z designed to engage astud upon an arm of the pivoted frame, all constructed and arranged to operate substantially as and for the purpose set forth.

4. In a feed-cutter, the driving-gear located entirely upon one side of the machine, in combination with a'shifting-gear for reversing or stopping-the action of said lnachine, composed ofv a frame ,pivotally connected to the lower feed-roll journal and carrying a pinion and gear-wheel, the shaft of the latter' consisting of a bolt and sleeve adjustable in said frame, a removable clutch-pinion journaled on said adjustable shaft,and a segment-lcv er pivotally connected to the gear side of said machine to vengage the pivoted frame, substantially as and for the purpose set forth.

In testimony that we claim the foregoing 'we have hereunto set our hands, at West Bend, in the county of Washington and State of Wisconsin, in the presence of two witnesses.
