CHARLES' K. MYERS, OF PEKIN, `ASSIGNOR FOR ONE-'HALF UFO HOROE TURRELL, OF TAZEWELL COUNTY, ILLINOIS.

Letters Patent No.V 99,695, dated February 8, 1870.

IMPROVEMENT IN HARVESTER-CUTTERS.

The Scheule referreio in these Letters Patent and making part of the same To all whom it may concern V.Be it known that I, CHARLES K. MYERS, of the city ot' Pekin, in the county of Tazewell, and in the State of Illinois, have invented an vImprovement in Sickle-Sections; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the 'annexed drawings, making a part of this specification, in which like letters of refe-rence refer to like parts, and in which- Figure 1 represents a perspective View.

Figui-e2, a perspective viewof the under side of the sickle. V

Figure 3, longitudinal elevation of sickle.

Figure 4, plan of block and device for securing the sections within the rod.

Figure 5, cross-section of sickle-rod.

Figure 6,. perspective View of one of the cutting-sections.

Figure 7, another yiew of the same.

This improvement relates to the setting and fastenings of the -shanks of movablel sections ofthe cuttingpart of' a sickle, such as those used in all kinds of hnrvesters, "reapers, mowers, headers, 85o.

B represents a cutting-section, the ends a a being nent at a right angle, and a cut or slot, d d, made in the angles, at opposite sides ofthe neck ofthe shank, and is intended to admit the inner edges of the sicklerod, a series of these sections being being inserted until the sickle-rod is full.

A represents the sickle-rod, which is a hollow rod of iron, made by bending np the sides, so that a crosssection will resemble the letter E, nearly, (see fig. 5.) The returned edges do not meet, but form ledgesI or shelves, e, on each side of the interior of' the rod, which ledges retain the shanksot the sickle-sections as they are inserted, entering the slots' ot' the shanks of' the same, represented at al d. The -ledges of the rod are Yseen at e e. A block, k, fastened to the interior of the rod, forms a stop, to 'retain the series of sections at that end ofthe rod.

O is an iron block, nearly filling the hollow ot the,y rod or sickle-back A, having a nipple or lug, t', at 'its outer end, which falls into a hole n ezu' the end of the rod A.

The inclined face of the block O lies against a second block, b, placed between the former and the last ofthe series of sections B.

A screw, It, inserted through the back ofthe sicklerod, brings thc inclined face ot' said block O with force enough to thoroughly. press together :and securefroni mot-ion or jar the whole series ot' cutting-sections inserted in the rod A.

By this invention, a ."cutting-section is easily removed from the sickle-rod, as, for instance, in case of breaking or bending one ofthe sections B, nothing more is necessary to be done than to remove the screw li., and with it the block O and the blocklb, and the sections, or any of them, can .be taken out, and fresh sections or a section inserted.

I claim, as my invention-f p 1. The sickle-rod A, when constructed with ledges e e, as stays for the cutting-sections, substantially described. Y 2. The cutting-sections B, constructed with lugsa a and slots d d, substantially as'shown and described.

3. The combination of the block or wedge C, its nipple or lug i, or equivalent stay, screw hand block b,

and block or stop le, for the purpose of' retaining and tightening the cutting-sections in the sickle-rod, substantially as described.

In testimony that I claim the foregoing sickle and movable sick1e-teeth, I have hereunto set my hand, this 13th day of December, A. D. 1869.

\Vituesses: C. K. MYERS.
