IMPROVEMENT IN STRAW-C UTTERS.

Specification forming part of Letters Patent No. 183,285, dated October 17, I876; application filed January 29, 1876.

To all whom it may concern:

Be it known that I, JOHN Q. ORosBY, of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Straw or Feed Gutters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being bad to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in straw-cutters; and has for its object to provide means whereby the knife may be readily adjusted to the mouth-piece or cutter-frame, and whereby those parts liable to break or to be bent may readily be replaced at small cost.

It consists in aremovable hollow axial stud, in a detachable hub or bearing for the knifelever, and in other mechanism, as hereinafter fully explained.

In the drawings, Figure 1 is a front elevation of my device complete. Fig. 2 is a top edge view of Fig. 1; and Figs. 3, 4, 5, 6, 7, 8, and 9 are detail views of the several parts.

a is the mouth-piece of the cutter, on which is formed the extension 00, to which the several parts hereinafter described are secured. a a are two clips or lugs attached to the extension a They have their inner sides under beveled or grooved, so that the edges of the supplemental plate or are hereinafter described will slip therein, and be held securely to the extension a b is the axial stud. It is made hollow, as shown at 12 and is held to the frame a by the retaining-screw 01, passing through the bore b and hole a in the extension a. It is connected with the plate or are I), with which it forms a single piece or casting, and may be readily removed when desired. The plate or are I) has its edges slightly beveled, so that it will slip into the under grooves on the clips a by which it will be held firmly in place. It will be seen that when the retaining-screw d is put through the stud b and hole a in the frame a, the plate or are I), with its stud b will be held as securely in place as if it was a part of the said frame. 0 is the hub or bearing by which the knife-lever is connected with the axial stud b thereto, and forming a part thereof, is the plate c, which oscillates or turns with the hub, and which is made to extend out flush with y the outer edge of the plate b, on which it slides desired.- d is a washer placed over the top of the stud b and hub 0 after the latter has been placed on said stud. e is the knife-lever, which is secured to the hub or bearing 0 by the screw or bolt 0. I

The knife-lever is provided with the extension 0 in the end of which is placed the setscrew 6 by which the knife may be adjusted to the mouth-piece. The screw 6 bears or abuts against the plate 0, and in adjusting the knife by turning the screw in or out the plate is not moved, and by reason thereof no strain will be placed on the hub 0 nor on the stud b. The plate 0 protects the screw from being worn away or bent, as would be the case did the end of said screw slide on a stationary bearing.

It will be readily seen that should any injury be done to the stud 11 or to the hub 0 these parts could be replaced at small cost.

It will be further understood that the plate 11, carrying the stud b could be secured to the extension a by means of screws or bolts passing through, the screw-heads being countersunk in the plate I), to permit the free movement of the are or plate 0; but I prefer the construction with clips, as described.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

' l. The plate b, provided with the hollow axial stud b secured to the plate or frame a by the clips c and screw d, substantially as Attached 2. The hub or bearing 0 provided with the dovetail groove 0 and oscillating plate or arc c, all constructed and operating substantially as and for the purpose set forth.

5. The combinationof the detachable hub and plate or are c with the removable hollow axial stud b and plate I), substantially as shown.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.
