THOMAS C. FISHER, OF ANDERSON, INDIANA.

FASTENER FOR SCYTH ES.

SPECIFICATION forming part of Letters Patent No. 374,052, dated November 29, 1887. Application filed September 24, 1884. Renewed December 3, 1886. Serial No. 220,599. (No model.)

To all whom, it may concern.-

Be it known that I, THOMAS C. FISHER, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Fasteners for Scythes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improve ments in snath-fastenings for scythes; and it has for its objects to provide for setting and holding the scythe-blade in any convenient position in relation to the snath against any tendency to accidental movement,as more fully hereinafter specified. These objects Iattain by the means illustrated in the accompanying drawings, in Which- Figure 1 represents a perspective view of my improved device; Fig. 2, a longitudinal vertical sectional view, and Fig. 3 abottom .view, thereof. Fig. 4 is a detail perspective of the disk.

The letter A indicates the base of the device, which consists of a flat metallic plate constructed with a ferrule, a, atone end, through which the end of the snath may be passed. The plate near the rear end is provided with an aperture, 1), through which a screw-may be passed to secure the device to the snath. The

plate is'also provided with a countersunk ap-' erture, c, theedges of which are provided with serrations d, and in said countersunk aperture is loosely secured a disk, D, its edge beveled at an. angle to correspond to the angle of the countersink, the said disk being confined in the aperture by means of abolt, e, and washer g. The disk is provided with an eccentrically-located enlargement, h, which has a recess, 'i, for the reception of the projection or tang at the end of the shank of the scytheblade, as more fully hereinafter specified. The plate A is provided'with a transverse rectangular slot, k, and the ferrule, directly above such slot. with an aperture, I, as indicated.

The letter 13 indicates a screw-bolt having an elongated eye, which sets in the transverse slot before mentioned. The threaded portion of the bolt passes'through the aperture in the a screw-nut, n, by which the loop or eye may be tightened upon the shank of the scytheblade.

The operation of myinvention is as follows: The snath near its end is provided with asuitable slot or opening through which the eyebolt above mentioned may be passed. The snath thus formed has its end inserted through the ferrule, after which the eyebolt is passed through the plate, ferrule, and snath. The device is then fastened to the snath by inserting ascrew through the aperture in the plate provided for the purpose, as before mentioned. Theshank of the scythe is then passed through the elongated eye on thescrew-bol t, and the proj ection at the end of said shank is inserted in the recess in the eccentric enlargement at the end of the beveled disk. The disk is then turned so as to set the scythe in the desired position, and the whole is secured by screwing up the nut so as to bind the parts firmly together. The plate or washer g is larger than the aperture with which it cooperates, a headed pin, e, serving to prevent the entire separation of the disk D, but allowing sufficient play to allow the ready adjustment of said disk. The proper adjustment having been obtained between the disk and its seat, both the disk and the scythetang are secured in place by simply turning the nut on the eyebolt. In this feature lies the gist of the invention.

What I claim as new is The combination, with the plate A, having ferrule a and aperture 0, with inclined toothed sides, of the toothed disk D, the plate of larger diameter than the aperture, the headed bolt seated in the disk, extending through the plate, and of sufficient length to allow disengagement of the disk with the toothed sides of the aperture, and the eyebolt B, all arranged as shown, whereby the proper manipulation of the eyebolt to secure the scythe-tang will force and hold the disk in place, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS C. FISHER.
