IMPROVEMENT IN STRAW-CUTTERS.

Tha Scimdule referred to in` these Letters Patent and making part of the same.-

To all whom it may conce/rn:

Be it known that I, ELLIS DOUTY, of Collomsville, in the county of Lycoming, and State of Pennsylvania, have invented new and useful Improvements in Straw- Cntters; and I do hereby declare that the following is 'a full, clear, and exact description thereof, which will enable those skilled in' the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a longitudinal vertical section of a`- strawcutting machine provided with my improvements, the vsection being taken at the line wfg of fig. 2. y

Figure 2 is a cross-section of the same machine, the section being taken at the line a: x, fig. 1.

Figure 3 is a detail front view of the gauge-board. Similarlettels of reference indicate corresponding parts.

This invention relates to those straw-cutting ma chines in which a straight knife or cutter is employed in a reciprocatingframe sliding vertically on the front v.npr-igllt's, and operating to bring the edge of the knife downward across the end of the box with a shear-cut.

My invention consists in the combination of parts, as will be hereinafter more fully described.

In the drawings- H is the feed-box, and

D, the front upright-s of the same.

A B is the cutter-frame, bearing the cutter G.

This frame is provided with blocks or proj cctions, C, which are recessed, to slide on the upn'ghts D, and thus guide the frame AB and its knife in their recprocal motion.

The gauge-board E is for the purpose of limiting the forward movement of -the straw, so as to eut or chop the same into short pieces of uniform length. o

This board is removable, its 'ends being formed with tenons, f, which t in slots or grooves, g, in the proximate `faces of the uprights D.

There are two pairs of such grooves in the uprights, one pair being in advance of the'other, so that theboard can be removed from one pair to the other, as?" the straw is to be cut longer or shorter, or be renwved altogether, when the straw is to be cut no particular?.`

with the under side of the box H by means of an elastic rubber strap, e, the naturaltension of which serves to raise the frame, and relieve the straw from the pressure of the presser-board b, when the 'attendants foot is raised, thus permitting the straw to be pushed up to the gauge-board E.

The presser-board is hung on a rod, connecting the sides d el of the fiame,to permit it to accommodate its. position to the straw.

1 is the handle of the cutter-frame. 4

I am aware that the pivoted presser-board is not new, in' itself considered, and I do not, therefore, so claim it; but

What I claim as new, and desire -to secure by Letters Patent, is l The elastic strap e, in combination with the feedboard H and the feed-frame, consisting of the crosspiecc a, sides d d, and pivoted presser-board b, all arranged as described, for the purpose speciled..
