IMPROVEMENT IN SlCV-THE-FASTENINGS.

The Schedule referred to in these Letters Patent and making part of the same.

T call persons to whom these presents may come:

Be it known that I, SAMUEL U. KING, of Windsor, of the county of Windsor and State of Vermont,- haveinvented an Improved Scythe-Smith Fastening; and do hereby declare the same to be fully described in the following specification and representediu the ac companying drawing, 'of which- Figure l denotes a top view of such fastening and the parts of a scythe andsnath to which it is applied;

Figure 2 is a transverse section taken through the clamp; l g

Figure 3 is another transverse section taken through the toe and its socket, to be hereinafter described;

Figure 4 is a side elevation;

Figure 5, a front end view; and

Figure 6 is a longitudinal sectipn'of the snath with the Scythe fixed thereto.

In the'said drawing the snath is shown at A as provided vvith a metallic ferrule, B, to encompass the snath near its end. 1

This ier'rule is to be constructed with a flat surface or bed, a, for the foot b of the s'cytheto -rest on, and within such bed, or so as to extend below it into the suath A, is a socket, o, provided at its ends with shoulders or abutments d (l, to rise 'above the bed.-

The said socket is to receive the toe e ofthe foot of the scythe, and also a slide, f,- whiclrmay be inserted in the socket and 'on either side of the foot,.for the purpose of adjusting suchl foot and blade, to either of two positions relatively to the scath.

Furthermore, 'at or near one corner of the outer end of the bed is a hooked or inelinedabutment or shoulder, g, and there extends through the middle of the ferrule, and beneath its bed, a 4hook or clamp, O,

`formed as represented, and provided with a male screw,

h, and a nut, t', the nut being` to work against a datA shoulder, la, projecting from the fer-rule, as shown.

The head of the clamp hooks n'pon the inner edge of the Scythe-foot D, and when the nut is screwed up the hook of theclamp will not only draw the heel of the Scythe-foot closely up to and under the shoulder g, but will hook over the said .footin a manner to hold it closely down against the bed, the shoulder g also operating to force and hold the foot down upon the bed.

The scytbe-fastening constructed as describedv and represented isone of great simplicity 'and eciency.

I am aware of theoscythe-fastening as Vdescribed in v the expired United States patent No. 7,989, granted 'March 18, 1851, to Ebenezer G. Lamsou, and, make no claim to any device, combination, or arrangement of devices described or represented in such patent, my invention consisting in au improved arrangement of the hooked clamp and itsl nut with reference to the stationary abutment and the toe-socket, as described.

In carrying out niy invention the clampaud nut are .arranged between the toe-socket and the -abutment, and not directlyv'opposite' or in the plane ofthe abutment, as they arein the Scythe-fastening of the y said LanIson, they being by preferencearranged midway between the-abutment and the toe-socket. v

In Lamsons fastenings it has been found in practicel that thejaw of the hooked clamp, by being directly opposite the abutment, operated with no practical ei'ect to force the toe laterally or in a direction transverselyiof the snath, and that in consequence thereof-there was a constant tendency of the parts to work loose. nut is' set up not only will the shank or foot b be forced by the clamp O strongly against the abutment g, but the toe e, at the same time and with about an equal power, will be set up firmly against thesupport-piece f, all of which renders the fastening of thev Scythe to the 4snath"se cure, `better, and less liable to displacement than-is the 'case with the Lamson fastening.

o It will moreover be seon that the form of thefclamp O causes it to force "the shank b against the plate a, and to hold the toe e 'in thel slot c, which may be of simple rectangular. form, capable of receiving the toeof any ordinary Scythe without alteration, whereas in the Lamson fastening a special adaptation ofthefor-In of thetoe was required-to adjust it to the slot-.1

I therefore claimi rIhe described Scythe-fastening as constructed with the hooked clamp '0, and its'. nut b arranged between the hookedabutment q and the toe-socket o, all being substantially as speciiied.' g
