UNITED STATES PATENT OFFICE.
ROBERT E. EDWARDS, OF WORCESTER, MASSACHUSETTS.
SCYTH E-SNATH FASTEN ER.
SPECIFICATION forming part of Letters Patent No. 711,558,,dated October 21, 1902.
Application filed January 3, 1901. Serial No. 41,964. (No model.)
To all whom it may concern:
Be it known that I, RoBERrB. ED'wARDs, a citizen of the United States, residing at Worcester, in the county ofNVorcester and Commonwealth of Massachusetts, have invented a new and useful Improvementin Scythe-Snath Fasteners, of which the following is a specification, accompanied by drawings forming a part of the'same,vin which Figure 1 represents the slabbed end of a scythe-snath to which the scythe is attached. Fig. 2 is a central longitudinal sectional view through the end of the scythe-snath on line 2 2, Fig. 1. Figs. 3, 4, and5 represent, respectively, the pivoted plate, clamping-bolt, and flanged washer of my improved scythe-snath fastener detached from the scythe; and Fig. 6 is a transverse sectional View on line 6 6, Fig. 1.
Similar reference-letters refer to similar parts in the different views.
My invention relates to that portion of a scythe-snath fastener by which the shank of the scythe is adjusted on the snath so as to vary the position of the scythe; and it consists in the construction and arrangement of parts hereinafter described, and set forth in the annexed claim.
Referring to the drawings, A denotes the end of a scythe-snath slabbed at one side, as at B, and provided on its end with a ferrule C and having an eyebolt D,- these parts being of the usual form of construction in snaths now in common use. Resting upon the slabbed surface Bis a plate E, provided at one end with a spurv F, projecting from its under side and held in a hole F in the scythesnath, forming a pivot for the plate. The plate is provided with one or more openings G to receive the usual lug on the shank of the scythe and an elongated opening H, concentric with the spur F, to receive a clamping bolt I, having a head I and carrying a nut I and Washer I Projecting from the under side of the head I and on diametrically 0p-' posite sides of the bolt are teeth J J, preferably triangular in their cross-section and adapted to engage a series of radial teeth K on the upper side of the pivoted plate E and on its surface which is adjacent to the elongated bolt-opening H. Recessedin the snath is a sleeve L, having a. flange L, with its upper surface flush with the slabbed side B of the snath. The sleeve L fits tightly within the snath and surrounds theclamping-bolt I, and its flange L forms a-bearing-surface for the under side-of the pivoted plate E. The plate E; as shown in the drawings, is provided with'two openings G G for the scythelug, a certain adjustment of thescythe being obtained by moving thelug from one opening to the other. Another and finer adjustment of the scythe is secured by releasing the clamping-bolt I and swinging the pivoted plate E to bring a new tooth on the plateinto engagement with the teeth J on the bolt-head.
I am aware that it is not new to adjust the scythe by means of a pivoted plate held in any position by a clamping-bolt, and I do not claim such broadly.
What I claim as my invention, and desire to secure by Letters Patent, is-
In a scythe-fastener, the combination with a scythe-snath having a slabbed side and an eyebolt for receiving the shank of the scythe of a socket-plate provided with an opening midway between its ends for the lug of the scythe-shank, said plate having at its end nearest said eyebolt a cylindrical projection on its under side entering'a socket in the snath and forming a pivot for said socketplate, an elongated opening curved concentrically with said pivot in the end of said socket-plate farthest from said eyebolt for an adj usting-bolt, radial teeth on the upper surface of said socket-plate and adjacent to saidcurved opening, an adjusting-bolt having teeth beneath its head to engage said radial teethand a flanged sleeve recessed in "the snath inclosing said adjusting-bolt and having its flange flush with the slabbed side of the snath and bearing against the under side of said socket-plate, substantially as described.
