IMPROVEMENT IN THE MODE 0F ATTACHING SCYTHES T0 THE SNATHS.

Specification forming part ot Letters Patent No. 1.213, dated July 2, 18:;9.

T0 all whom, it may concer/t:

Be it known that I, EBENEZEE G. LAMsoN, of Shelburne Falls, in the county of Franklin and Commonwealth of Massachusetts, have nvented a new and useful Improvement in the Mode of Hanging the Scythe to the Snath; and lido hereby declare that the following is a full and exact description thereof, reference being had to the drawings accompanying and inaking part of this specitication, and the same parts are designated by the same let-ters of reference in all the diierent iigures.

Figure l of the drawings is a perspective View of the top of the snath and scythe; Fig. 2, an. under view of the same, Fig. 3, a view of the under side of the snath with the scytlle removed, and Fig. fl the hook that contines the shank ofthe scythe to the snath.

At the heel of the common snath I flatten the under side, similar to what is commonly called spotting,f17 and also the opposite or upper side, and cover the surfaces so iiattened with a metallic plate, a, to lthe distance of about ve inches from the heel of the snath, and the plate, which is bent around the heel of the snath, is iirinl y secured by screws or rivets.

Near the edge of theplate a. (at either edge) is formed a niortise, b, parallel with the side ofthe snath, through the two opposite sides ofthe plate a and the snath, about two inches long and one inch from the heel of the snath, and about three-eighths of an inch in width, which receives the hook-bolt c, as shown at Figs. l, 2, 3, and et.

rlhe claw-holes d, Figs. 2 and 3, that coniine the claw e at the upper endof the shank, are three or more in number, and placed obliquel y in the snath at an angle of about fortyiive degrees, so that the corners of the several holes are united, as shown at Fig/3. These holes d are formed for hanging the scythe in or out at the point by changing the claw from one hole to another at the pleasure of the operator, and by their being placed obliquely in the snath the scythe can be adjusted to a greater nicety than if they were placed transversely and parallel to each other, which would require, in the latter case, sufficient strength of metal or wood between the holes to resist the pressure ofthe claw.

The hook-bolt c, that contines the shank y ofthe scythe to the under side of the snath, has a turn or arm, h, projecting at right angles from the bottom of the long part of the bolt, and atthe end ofthe arm h another turn is given to it in a vertical direction, or parallel to the bolt c, which forms the hook j, and the distance between the bolt c and hookj is equal to the width of the shank at the mortise b, as shown in Figs. 2 and 4. A screw is formed at the upper end of the bolt e, and a nut or female screw applied thereto, which coniines the scythe to the snath, as seen at Figs. l and 4. The lower part of the bolt c is square, and corresponds in size with the width of the mortise b, in which it is inserted, and as the clawof the scythe is moved from one hole to another the heel of the scythe receives a lateral motion equalto the diameter of the hole d, andthe mortise b admits of a lateral movenient tov the hook-bolt, thatit may correspond with and lit firmly to the edges of the Scythe, as at Fig. 2.

Vhat I'elaini as myinvention, and desire to secure by Letters Patent, is-

The method ol' hanging sc'ythes by means of the mortise b and hook-bolt c, in combination with the claw-holes d, the whole being arranged in the manner and for the purpose herein specified.
