SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 787,354, dated April 18, 1905.

Application filed July 11,1904. Serial No. 216,074.

Be it known that l, Unamacs Cassnn, a citizen of the United States, residing at Durbin, in the county of Pocahontas and State of W est Yirginia, have invented anew and useful Sawf llandle, of wlnch the following is a specitication.

This invention relates to sawhan(.lles, and has for its object to provide for the convenient attachment and detaclnnent of wooden handles with respect to crosscut-saws and at the same time to maintain a rigid and durable connection between the handle and the sawblade. In devices of this character the washer at the inner end of the handle becomes worn by contact with the adjacent end of the sawblade sutticiently to permit looseness of the handle, and in view of this objection it is an important object of the present invention to provide for the convenientadjustment of the washer, so as to present new or unworn portions of the washer to the end of the sawblade, so as to insure a snug and rigid attachment of the handle.

\Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accom- 1 panymg drawings, and particularly pointed 1 out in the appended claim, it beingunderstood thatchanges in the form, proportion, size, and minor details may be made within the scope of the claim without departing from the spirit or sacriticing any of the advantages of the invention.

in the drawings, Figure 1 is a longitudinal sectional view of a saw-handle embodying the features of the present invention. Fig. 2 is a detail perspective view of the adjustable washer. Fig. is a cross-sectional view on the line 3 of Fig. 1. Fig. t is a detail perspective view of the handle with the ferrule removed. nal sectional view of the ferrule removed from the handle.

Fig. 5 is a detail longitudi' [like characters of reference designate cor- 1 the ferrule.

ner end slightly reduced, so as to [it within the metallic ferrule 2, and also provided with a longitudinal polygonal socket 3 to snugly receive the polygonal internally screwthreaded seat 4:, which has its outer end connected by an integral web 5 with the interior of the ferrule, from which it tapers inwardly to form a tapered annular space (5 between the seat and the walls of the ferrule for the reception of the socketed terminal of the wooden handle, which is wedged therein. In the circular space at the front of the web 5 there is an annular flange T.

For direct connection with the saw-blade, a portion of which has been shown at 8, there is a yoke-bar t), which receives one end of the saw-blade within the yoke or slotted portion thereof and is provided with a screw-threaded stem 10, designed to be engaged with the screw-threaded seat et of the ferrule, so that by turning the handle upon the stem the former may be fed down against the end of the saw-blade, so as to grip the latter between the handle and the outer end of the yoke-bar.

Interposed between the outer end of the forrule and the adjacent edge of the saw-blade is a metallic washer 11, which is somewhat greater in diameter than the ferrule and is provided with a central boss or hub 12,whicl1 projects into the open inner end of the forrule and is provided with an annular groove 13, loosely receiving the flange 7, so as to form a swiveled connection between the washer and It will here be explained that the ferrule 2 is cast over the hub 12 of the washer in the well-known manner of casting one member loosely upon another member by the application of some friable material upon the internal member to prevent uniting of the members, the material being afterward worked out so as to leave the members united, but loosely connected. \Vhcn the outer face of the washer becomes worn at any point by contact with the edge of the saw-blade sutliciently 9 to permit looseness of the handle, the handle may be rotated upon the stem 10, so as to back the same off from the saw-blade, whereupon the swiveled washer may be turned so as to present a new or unworn portion to the edge of the saw-blade, and when the handle is again set back to its original position the saw-blade will be snugly gripped between the yoke-bar and the handle. The washer 11 closely embraces the bar and is slightly greater in diameter than the ferrule, thereby to have a broad bearing upon the back of the saw-blade and to permit of its peripheral edge being projected sufficiently to afford a finger-grasp, and thereby facilitate turning of the washer when desired.

It will here be explained that as the washer is swiveled upon the ferrule it remains fixed in engagement with the back of the sawblade when the ferrule and handle are being turned to tighten the connection between the handle and the saw-blade, thereby obviating wear upon the washer, as would be occasioned if the washer turned with the ferrule across the relatively sharp corners at the back edge of the saw-blade. Furthermore, the broad flat washer has a more extended bearing upon the saw-blade than would be obtained by the end of the ferrule, and therefore a more rigid and durable clamping action is had between the handle and the saw-blade.

From the foregoing description it will be noted that the ferrule and the threaded seat are integral, thereby producing a strong and durable member with its parts always connected in position for ready assemblage with the handle, and the washer has a positive swiveled connection with the ferrule, so as to prevent displacement and loss of the washer when the handle and the yoke-bar are disconnected. Moreover, the washer may be conveniently adjusted to present an unworn portion to the edge of the saw-blade, so as to maintain a rigid connection between the handle and the saw. It is preferred to have a long pitch for the threads of the yoke-bar and the seat in order that a few rotations of the handle may be sufficient to back the same away from the sawblade and release the handle therefrom.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent,

A device of the class described comprising a saw-engaging bar having a threaded stem, a handle having a terminal polygonal socket, a ferrule fitted to the handle and provided with an internally-threaded seat having a polygonal wedge-shaped exterior spaced from the walls of the ferrule and fitting the polygonal socket of the handle, an inner annular flange within the ferrule at the front of the seat, and a washer having a hub rotatable within the outer end. of the ferrule and provided with an external annular groove receiving the flange of the ferrule.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

CHARLES CASSEL.
