Specification forming part of Letters Patent No. 42.081, dated March 29, 1864.

To all whom lit may concern.-

Be it known that-LVPINCKNEY Feos'r, of Springfield, county of Windsor, and State of Vermont, have invented a new and Improved Scythe-Fastening; and I do hereby declare that the following' is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure Lisa view representing a Scythe se; cured to its snath according to my invention. Fig. 2 shows a side view ofthe fastening. Fig. 3 isa section of Figs. 1 and 2, taken at the point indicated by red line w a'. Fig. (l is a perspective view ofthe looped clamp. Fig. 5 is a perspective view of the perforated claw-plate inverted. Fig. (5 is a perspective view of the leather wedge used for adjusting the point of the scythe, either up or down.

Similar letters of' reference indicate corresponding parts in the several figures.

The object of my invention is to enable the mower t-o readily adjust and to firmly fasten his scythe in any required position upon the snath without the necessity of bending or twisting the web or arm of the Scythe for this purpose, as will be hereinafter described.

To enableothers skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In theaccoinpanying drawings, A represents the lower-most end of the snathor handle of the implement. B is the Scythe-blade, of which c is its handle, and a the claw formed on the small end thereof, as shown in Figs. I and 2. The lower end of the snath A is cut ont so as to leave a iiat surface, b, adapted to receiye the corresponding surface ofthe Scythe-handle c, and the extreme end of A receives on it aferrule, C, which has two flat surfaces, cc', through which perforations are made for receiving the screw-tapped ends of a loop, D, and also the screws d d, which operate this loop and draw it up, so'as to clamp and confine the lower part of the handle c against the flat surface of the ferrule. or against a leather wedge, which will be hereinafter described. The loop D is constructed with nuts e e on its bent ends,which receive the ends of the screws d d, and which a enter perforatons made through the flat surrespective recesses and introducing the arm a of the scythe-blade under the loop'D, the latter can be drawn up tightly' against said arm by means of the two screws d d, and the arm may be thus firmly clamped to the snath. The claw or right-angular projection ci', whichis formed on the small end of the Scythe-handle a, is received by a perforated plate, E, which is firmly 2. g, through it, the sides of which recesses form supports for preventing the arm a from having anylateral motion when the claw a is adjusted in any one of these recesses. Four are used for the purpose o f adjusting the point` of the Scythe toward or from the snath, and by inserting the claw into the proper hole in said plate the mower can give the desired pitch to his scythe.' I iind'that it is'impossible by the use of the ordinary slides to make as much variation'of the point of the scythe toward or from the snath as is necessary in order to usel conveniently allrlengths and shapes of scythes without havingtheclaw bind in some positions and loose iu others. To avoid this diffiofthe plate E, which extendk deeper into the wood than does the claw. By this arrangement I ani enabled to bring the holes sufficientupon theface of this plate E. The sides of these perforations against which the claw bears are' made converging toward the loop D, for the purpose of adapting the holes to receive the claw freely in whatever angle the arm a may be placed with respect to the lengthof the snatli. The loop D is made of sufficient length to admit of a variation of the handle a plate E) apart, and thus the loop will clamp the arm a tirmly in whichever hole the claw may be set. By having a screw at each end of the loop D either end may be setup so as to fasten the arm firmly, whatever ina-y bei-ts position. This cannot be done by a single screw, as the draft would then be equal on both ends of the loop, and it would be necessary to keep the arm in the center of the loop, or the bearing would only be on one side thereof.

The leather wedge G, it will be seen, is much thinner on one side than itis on the other. This wedge is inserted between the arm a and flat Asurface of the snath for the purpose of secured to the snath, as shownin Figs. l and This plate E is formed with four recesses,`

culty I have two spurs, h h, oil the under side ly near together to admit of four'being made Y equal to the distance ofthe two claw-holes (inthrowing out the heel of the Scythe more or the arm a to one side or the other ofthe clampless, according to circumstances, and also for the purpose of raising the edge of the Scythe to a higher angle from the ground whenin use than it otherwise would be, and also for the purpose of varying the point of the Scythe above or below a level with the spotting. The former object is accomplished by increasing or diminishing the thickness of leather under the heel of the scythe, and the latter object is effected by increasing or diminishing the thickness of leather under one side or the other of the arm a. These two adjustments are made by means of the leather wedge G, shown clean ly in Fig. 6, which is beveled laterally as well as longitudinally. The longitudinal slot il in this wedge corresponds to a slot, 7.1which is formed in the surface c ofthe snath for allowingthe Scythe to be removed 4from the snath withoiit entirelyy det-aching the loop D, the groove@ receiving the claw as the Scythe is detached.

From the above `description it will be seen that my improved fastening consists of' a very few parts, and that the Scythe can be adjusted in any required position upon the snath, and then rigidly 'secured in place by a very simple manipulation.` Y j y In adjusting the point of the scythe to or from the snath, by changing the claw te from one hole in plate E to anotherthe amount of movement can be nicely regulated by slipping ing-loop D.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Theloop D, constructed with screw-tapped ends fitting into recesses formed in the snath, in combination with the two screw-fastenings d d, the whole constituting a. clump for securing the scythe to its snath, substantially as described.

2. The perforated claw-plate E, when constructed substantial] y as and for the purposes described.

3. The construction ot' the ferrule 4(l with poses described. i
