SCYTHE FASTENING.

Application filed August 9,1924. Serial No. 731,191.

The present invention has for its object the provision of means for securing a scythe to a snath in an adjusted position by the use of a single ring or band and precluding any loosening or displacement thereof.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in'the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming part of the application:

Figure 1 is a perspective view of the tang end of a scythe and the scythe end of a snath provided with fastening means embodying the invention,

Figure 2 is a plan view of the parts shown in Figure 1, as seen from the top side,

Fig. 3 is a perspective view of the bottom plate, and

Figure 4- is a detail perspective view of the tang end of the scythe.

Corresponding and like parts are referred to in the following description and desig nated in the several views of the drawings by like reference characters.

The numeral 1 designates a scythe snath which may be of any approved construction. The numeral 2 designates the tang of a scythe, the same having alaterally disposed lug 3 at its extremity. A plate 4 is secured to the top side of the snath 1 and is provided in its upper side with a groove 5. A plate 6 is secured to the bottom side of the snath 1 and is provided at opposite ends with diagonally disposed lips 7 which engage opposite sides of the snath 1 to sustain the strain and relieve the plate fastenings of the major portion of the lateral strain when the implement is in operation. An abutment or shoulder 8 depends from the outer end of the bottom plate 6 and constitutes a stop to engage the tang 2 and materially assists in holding the scythe in the required adjusted position. A transverse slot 9 is formed in the inner end of the bottom plate 6 and openings or notches are provided at opposite sides thereof to receive the lug 3 of the tang 2, whereby to hold the latter and the scythe in the required adjusted position. A ring 10 encir cles the scythe end of the snath 1 and engages the tan;; 2. A set screw 11 threaded into a side-of the ring 10 is adapted to engage the groove 5 of the top plate 4 and prevent turning of thering when properly positioned and tightened.

It is observed that the fastening is such as to enable the successful use of a single clamp ring the lug 3 and the abutment 8 sustaining the working strain and preventing displacement of the scythe when clamped to the snath by means of the ring 10. Adjustment of the scythe is effected by enteringthe lug 3 in any one of the lateral openings or notches of the transverse slot 9. When effecting the adjustment, the I set screw ll'is loosened and the ring 10 moved to release the tang 2 and after the scythe has been adjusted, it is made secure by replacing the ring 10 so as to engage the tang 2 and retightening the setscrew 11.

What is claimed is: i

1. In a scythe fastening for detachably fastening to a snath the usual scythe-blade tang having an upturned lug at its free end, the combination. of a plate secured. to

the side of the snath at its blade-receiving end and havinga flat surface against which the scythe-blade tang lies, said plate having a plurality of recesses at different transverse positions to receive said upturned lug in anyone of said positions, said plate also having near its outer end an abutment which is engaged by the tang-edge on the opposite side from that from which the scythe-blade projects, a clamping ring for engaging said tang to clamp it upon said plate with the tang-edge against said,abutment, said clamping ring being of substalr, tially larger diameter than is said snath so that it may be shifted freely therealong when released and may take somewhat different transverse and angular positions thereon to correspond with the different positions of said lug, and a set-screw in said clamping ring for co-operating with the snath opposite to said plate to draw said clamping ring against the tang and to press both the tang and the snath against the plate.

2. In a scythe fastening for detachably fastening to a snath the usual scythe-blade tang having an upturned lug at its free end, the combination of a plate secured to the side of the snath at its blade-receiving end and against which the scythe-blade tang lies, said plate having a recess to receive said upturned lug, said plate also having near its outer end an abutment which is engaged by the tang-edge on the opposite side from that from which the scythe-blade projects, a clamping ring for engaging said tang to clamp it upon said plate with the tang-edge against said abutment, said clamping ring being of substantially larger diameter than is said snath so that it may be shifted freely therealong when released, and a set-screw in said clamping ring for co-operating with the snath opposite to said plate to draw said clamping ring against the tang and to press both the tang and the snath against the plate.

3. In a scythe fastening for detachably fastening to a snath the usual scythe-blade tang having an upturned lug at its free end, the combination of a plate secured to the side of the snath at its blade-receiving end and having a fiat surface against which the scythe-blade tang lies, said plate having a plurality of recesses at different transverse positions to receive said upturned lug in any one of said positions, said plate also having near its outer end an abutment having a convex face which is engaged by the tangedge on the opposite side from that from which the scythe-blade projects, a clamping ring for engaging said tang to clamp it upon said plate with the tang-edge against said abutment, said clamping ring being of substantially larger diameter than is said snath so that it may be shifted freely therealong when released and maytake somewhat different transverse and angular positions thereon to correspond with the difierent positions of said lug, and a setscrew in said clamping ring for co-operating with the snath opposite to said plate to draw said clamping ring against the tang and to press both the tang and the snath against the plate.

4:. In a scythe fastening for detachably fastening to a snath the usual scythe-blade tang having an upturned lug at its free end, the combination of a plate secured to the side of the snath at its blade-receiving end and against which the scythe-blade tang lies, said plate having a recess to receive said upturned lug, said plate also having near its outer end an abutment which is engaged by the tang -edge on the opposite side from that from which the scythe-blade projects and also a finger projecting from the plane of the plate near the outer end of the plate and against the surface of the snath on the same side as the scythe-blade projects so that it helps to transmit thrust from. the plate to the snath, a clamping ring for engaging said tang to clamp it upon said plate with the tang-edge against said abutment, said clamping ring being of substantially larger diameter than is said snath so that it may be shifted freely therealong when released, and a set.- screw in said clamping ring for co-operate ing with the snath opposite to said plate to draw said clamping ring against the tang and to press both the tang and the snath against the plate.

5. In a scythe fastening for detachably fastening to a snath the usual scythe-blade tang having an upturned lug at its free end, the combination of a plate secured to the side of the snath at its blade-receiving end and having a fiat surface against which the scythe-blade tang lies, said plate having a plurality of recesses at difierent transverse positions to receive said upturned lug in any one of said positions, said plate also having near its outer end an abutment which is engaged by the tang-edge on the opposite side from that from which the scythe-blade projects, a clamping ring for engaging said tang to clamp it upon said plate with the tang-edge against said abutment, said clamping ring being of substantially larger diameter than is said snath so that it may be shifted freely therealong when released and may take somewhat different transverse and angular positions thereon to correspond with the different positions of said lug, and a set-screw in said clamping ring for cooperating with the snath opposite to said plate to draw said clamping ring against the tang and to press both the tang and the snath against the plate, said clamping ring having a tangengaging surface which engages the opposite edges of the tang oppositely obliquely.

In testimony whereof I afix my signature.

JOHN W; BOREN.
