Specification of Letters Patent.
SCYTHE.
Patented Mar. 30, 1915.
Application filed July 13, 1914. Serial No. 850,694.
' To all whom it may concern:
Be it known thatI, MAnoUs M. BAn'rLETT, a citizen of the United States, residing at Geneva, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Scythes, of which the following is a specificatlon, reference being had to the accompanying drawin s.
Fly invention relates to certain new and useful improvements in scythes, and more particularly to such as shown and descrlbed in Letters Patent No. 992,476, granted to me May 16, 1911. In the construction shown in the Letters Patent referred to, one of its features consists of a substantially V-shape rib on the under side of the blade adjacent and parallel with the flange on the rear edge, and a combined tang and back support having its rear edge adapted to fit against the front side of the back flange of the blade and formed with a downwardly extended tongue corresponding with the interior of the V-shape rib of the blade, and with a web lying upon the upper flat surface of the blade to which it is secured by suitable rivets, etc. I have found from practical experience that although the construction referred to produces a reasonably strong and rigid relation between the blade and the tang a very much stronger union is secured by my present invention, whlch consists generically in substituting for the V- shaped rib and corresponding tongue the construction hereinafter and in detail described.
In order that my invention and its advantages may be fully understood I will proceed to describe the same referring by numerals to the accompanying drawing in which Figure 1 is a perspective view of the heel portion of the scythe blade embodying the features of my invention; Fig. 2 is a transverse section on the line aa of Fig. 1, but with a rivet shown to clearly indicate the manner of securing the parts together, such rivet not-being shown at the line a-a of Fig. 1; Fig. 3 is a similar section on the line b?) of Fig. 1, the rivet being omitted in order to accentuate the relation of the parts shown; Fig. 4 is a detail longitudinal section on the line 0-0 of Fig. 1; and Fig. 5 is a detail inverted perspective view of a portion of the back support and tang.
Similar reference numerals indicate like parts in the several figures of the drawings.
1 is the scythe blade of sheet metal and formed at its rear edge with a flange 2, in clining slightly to the rear. In lieu of the V-shape rib shown in the Letters Patent referred to I form a groove 3 of the form shown most clearly in Fig. 2 in order that the groove in the upper surface of the blade adjacent to the flange 2 shall have a flat bottom instead of the V-shape bottom. The combined tang and back support, comprising the arm 4, and tang 5, is adapted for connection with the blade 1 and has the rear edge of the arm 4 formed with a strengthening rib 6, (see Fig. 8) of longitudinal and cross section form, corresponding with the flange 2 and groove 3, so that when placed in position upon the blade the bottom surface of the rib 6 and the upper surface of the groove 3 will be flat and in parallel contact and of such width as to permit the employment of suitable rivets 7 passing through the two parts 3 and 6, in addition to the rivets 8 usually employed to fasten the lateral flat extension to the blade. The tang is also formed with a shoulder 9 to bear snugly against the heel end of the blade, and also with a shoulder 10 to bear against the back edge of the blade, substantially as shown in the Letters Patent hereinbefore referred to. In order to differentiat-e my present invention from said Letters Patent, attention is called to the fact that in the latter case, and by reason of the cross section form of the blade and combined tang and arm, the rivets employed for securing the two parts together must of necessity be used through the laterally extended flat portion of the arm, and hence in time and under continued use of the scythe the leverage action upon such rivets is liable to produce looseness between the parts, while in the construction shown in my present improvement the rivets 7 are passed directly through the groove 3 and rib 6 and cooperate with the rivet 8 to establish a fixed, immovable relation of all the parts. With the construction shown and described it will be seen that the web or edge of the scythe when in use may be set low to the ground.
Having described the construction and advantages of my improvement, what I claim as new and desire to secure by Letters Patent is:
The herein described scythe comprising a blade formed With a back flange, and a groove having a fiat bottom, and a combined tang and back support having an arm provided With a strengthening rib at its rear edge conforming in cross section with the groove in the blade, the two parts, namely the combined back and tang, and the blade secured together by rivets passing through the rib and the bottom' of the 10 groove, substantially as and for the purpose set forth.
In testimony whereof I hereunto aflix my signature in the presence of two Witnesses.
