HENRY o. TURNER, on GAZENOVIA, NEW YORK.

IMPROVEMENT lN HAY-KNIVES.

Specification forming part of Letters Patent No. 202,487, dated April 16, 1878; application filed February 19, 1878.

To all whom it may concern:

Be it known that I, HENRY O. TURNER, of Gazenovia, in the county of Madison and State of New York, have invented new and useful Improvements in Hay-Knives, of Which the following, taken in connection with the accompanying drawing, is a full, clear, and exact description.

This invention relates to improvements in hay-knives designed for cutting hay or straw from the mow or stack; and it consists, essentially, in a novel construction and combination of its constituent parts, whereby an implement is obtained which is strong, durable, and effective in its operation, easily manipulated, and readily repaired.

The invention is clearly illustrated in the accompanying drawing, wherein Figure l is a front view of my improved implement; Fig.2, a side view of same; Fig. 3, a rear view, and Fig. 4 an enlarged view of one of the sections of the knife detached.

Similar letters of reference indicate corresponding parts.

Experience hasestablished the fact that a single knife having rearward-diverging cuttin g-edges allows the hay or straw, in a great measure, to yield to the approach of the knife, and thus deprive the latter of its effective ness. Hence a series of such knives has been arranged side by side, so as to form converglng cutting-edges, which, in conjunction with each other, produced the desired jefiect. It is' this latter class of implements to which my improvements pertain.

In the drawing, It represents the knifeproper, which, for the purpose of improving its effectiveness and of facilitating the sharpening and repairs of same, I construct of two or more sections, 8, of steel plate, having their respective divergent cutting-edges terminating with parallel square shoulders at at the sides, by which the several sections are united and made to brace each other laterally. These sections are riveted or bolted to a blade, b, which has its bottom edge formed with a series of V-shaped extensions, 0, fitted to the back of the sections 8, to thoroughly brace and stiffen the same.

The blade b is of triangular form, having its sides divergent from the handle h toward the knife 70. For the purpose of bracing this blade and preventing it from yielding to the transverse strain when in use, it is provided with a flange or rib, 1", along its side edges, which ribs, extendingfrom the handle h outward, brace the said blade both longitudinally and transversely. Its central part is braced by the handle h, which is fitted between the blade I) and the shank d, which latter is permanently attached at its lower extremity to the blade b, and has its upper .portion free from same, and extended some distance beyond the upper end thereof.

The handle is secured between the blade I) and shank d by means of bolts or rivets pass in g through the three parts, and an additional rivet or bolt passing through its upper extension and the handle, and properly clinched or otherwise fastened.

e is the step or foot-piece for applying the foot for forcing the knife into the hay. It is cast onto a shank, f, by which it is attached to the implement. The shank f is of sufficient length to overlap the end of the shank d, and is secured by a bolt or rivet passing through the lower extremity of the shank f, and through the shank d and the handle h, and by a bolt through its upper end and the handle. thus bracing the handle at its junction with the shank d.

The upper surface of the step e is serrated, to prevent the foot from slipping when applied during the manipulation of the implement.

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

l. The knife k, composed of two or more sections, 8, having their respective divergent cutting-edges terminating with the parallel square shoulders a, and united with the latter abutting against that of the adjacent section, in combination with the blade I), hav ing its bottom edge formed with a series of V-shaped extensions, 0, fitted to the back of sections 8, substantially as described and shown, for the purpose set forth.

2. The triangular blade I), re-enforced at its sides by ribs 1, and provided at the center with shank d, permanently attached thereto In testimony whereof I have hereunto set at its lower extremity, and free from same my hand this 8th day of February, 1878. from thence up, and extending above the same, in combination with the handle h, in- HENRY O. TURNER. serted between the shank d and blade I), and
