IMPROVEMENT IN FEED-CUTTERS.

Specification forming part of Letters Patent No. 137,] 68, dated March :25, 1873.

To all whom it may concern:

Be it known that we, WARREN S. BARTLE- and JAMES GARLOGK, of Newark, in the county of Wayne and in the State of New York, have invented certain new and useful Improvements in Feed-Gutter; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of our invention consists, first, in the means for adjusting the knife to the mouth-piece; second, in the means for attaching the knife-lever to the rock-shaft; third, in the construction and mode of attaching the adjustable gage-plate.

In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation,referring to the annexed drawing, in which- Figure l is a perspective view of our entire feed-cutter. Fig. 2 is a side elevation, and Fig. 3 a horizontal section, of the front part of the same. Fig. 4 is a front view of the box, and Fig. 5 shows the gage-plate.

A represents the box of our feed-cutter, supported upon the frame B. At the front end or mouth of the box A is a metal frame, 0, one end of which projects beyond the side of the box and forms the front bearing a. for

the rocking shaft D, to which the knife-lever E is attached. I) is the knife, attached to said lever E. On the rocking shaft D, immediately in rear of and against the bearing a, is placed a collar, G, the rear end of which is camshaped, as shown in Fig. 2, and bears against a rib or projection, d, onthe shaft. The camcollar Gr is secured by a set-screw, e. The rear end of the rock-shaft D is supported in an adjustable or movable bearing-bar, H, attached to the under side of the box A.

By turning the cam-collar G on the shaft D, the rib or projection 01 bearing against the cam'surfaee, the shaft is moved endwise, and

thus the knife 12 is readily adjusted to or from the mouth-piece G of the box, as may be desired, and the bearing bar or box H moved to correspond.

The advantages of this part of our improvemeut consist in cheapness of construction,

durability, and facility of adjustment. The movable parts, together with the knife, may be quickly taken from the body of the machine, and put away when not in use, and readily replaced when wanted.

The front or outer end of the rock-shaft D is cut square or straight on three sides, as shown in Fig. 1, and the inner end of the knife'lever E has a forward-extending projection, 6, recessed to fit over said portion of the shaft, and is fastened to the shaft by a bolt and nut, f.

By this means of fastening the lever and rock-shaft together we obviate the necessity of boring out the hub of the knife-lever, and. the turning of the shaft to fit the same, thereby lessening the cost of construction, and also of repairing, which can be done with dispatch should either of the parts be broken by accident or otherwise.

H represents the gage-plate, having a curve or bend at m, as shown, near its inner end, and said end slotted and shaped to fit over or on the projection c of the knife-lever. A crescent-shaped washer, h, is also placed on said projection against the plate, and the whole fastened together and to the knife-lever by a bolt and nut, 71. This gage is readily adjusted for cutting the different lengths by simply loosening the nut of the bolt i without taking it from the bolt. Without the crescent-shaped washer h it can be adjusted for two different lengths, and with it for four. By placing the gage with the curve at in and inside the crescent, the length of cut will be half an inch; the same outside the crescent, the cut will be one inch. Then by putting the curve out and the gage inside the crescent the out will be one inch and a half; and by putting it outside the crescent the cut will be two inches. I represents the stop for the knife-lever, c011- sisting of a wood pin, m, passing part way through the leg of the frame B, and an iron bolt, 12, passing through the center of the pin and through the leg, and secured by a nut on the back side.

We prefer to use this construction of stop, as it possesses advantages, in practice, over those made wholly of metal.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The cam-collar G and the rock-shaft D, provided with rib d, in combination with the bent knife-leverE and the knife b, all constructed substantially as and for the purposes set forth.

2. The bent knife-lever E, with a projection, e, at the end, having an angular recess, in combination with the rock-shaft D, having a corresponding projection, upon which the recessed end of the lever is secured by a bolt, all substantially as set forth.

3. The reversible and bent gage-plate H,

constructedas shown, with a forked end, and secured to and adjustable upon the lever E by means of the Washer h and bolt i, substantially as set forth.

In testimony that we claim the foregoingv we have hereunto set our hands and seals this 13th day of January, 1873.
