SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 624,292, dated May 2, 1899.

Application filed J anuary 14, 1899. Serial No. 702,158.' (No model.)

To aZZ whom it may concern.-

Be it known that 1, CHARLES W. BYHAM, a citizen. of the United States,residing at Kushequa, in the county of McKean and State of Pennsylvania, haveinvented certain new and useful Improvements in Saw-Handles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in saw-handles, and especially to a handle which may. be detachably connected to a crosscut or other saws and quickly detached when it is desired to apply the handle to various saws.

More specifically, the invention consists in the provision of a handle which has a rightangled grooved portion adapted to receive one corner and a portion of the longitudinal and end edges and held in place by means of a split rod or bar which is provided with a tightening thumb-screw at one end and its other saw engaging end being provided with a right-angled projection designed to be sprung overthe saw and through the aperture therein.

To these ends and to such others as the invention may pertain, the same consists in the novel construction, the combination, and adaptation of parts, as will be hereinafter more fully described and then specifically defined in the appended claim.

My invention is clearlyillustrated in the accom pan yin g drawin gs, which, with the letters of reference marked thereon, form a part of this application, and in which- Figure 1 is a side elevation of my improved handle shown as attached to one end of a saw. Fig.2 is a sectional view on line 2 2 of Fig. 1. Fig. 3 is a detail view of the collar and tightening-screw for holding the wooden part of the handle to the metallic saw-en gaging part.

Reference now being had to the details of the drawings by letter, A designates the saw, and B the metallic portion of the handle, which is provided with a right-angled groove B, the outline of which is shown in Fig. 1 of I the drawings. In this socket thus formed by the grooveone corner of the saw is adapted to be held, as shown. In order to hold the saw in the groove or socket provided therefor, a bar B is employed, which is split, as shown at C, forming two arms D and D, the former of which has a right-angled extension D adapted to fit through an aperture E in the end of the arm D, as shown. The opposite end of said bar C is threaded, as at F, and about said threaded portion a tighteningscrew H is carried. The said bar 0 is made, preferably, of a spring metal, so that the arms thereof may be sprung laterally so as to allow said bar to be placed over the saw-blade for the purpose of allowing the right-angled extension D to engage in one of the apertures A in the saw. The arm D will then be held normally with its extension through the saw, the free end of the arm D engaging in-the aperture E in the end of the arm D, and no nut will be necessary to hold the said bar in such locked position, retaining the sawsecurely in the position shown in Fig. 1 of the drawings. After the said bar has been attached to the saw the tightening-screw H may be screwed down to further securely hold the parts together.

In a projecting portion of the metallic sawengaging member is a collar 19, which is provided to embrace the wooden handle M, said collar being formed of two resilient portions held together by means of a tightening-screw N. This screw arries on its threaded end a tightening-nut N and has its opposite end end of an arm of the collar.

From the foregoing it will be noted thatin the provision of a handle as shown and de scribed the said handle may be readily applied tovarious forms of saws and may be readily detached when desired.

Having thus described myinvention, what I claim to be new, and desire to secure by Letters Patent, is

A handle and fastening device for saws, comprising the shank portion B having a right-angled recess in which one corner of the saw-blade is adapted to engage, combined with the retaining-bar O which is forked and provided with arms D and D, the latter of contracted, so as to retain the screw in one which is a ertnred near its end, the arm D cessed ortion andawin -nut on said threadp a a having a right-angled end, said bar designed ed end, all as shown and described. to to straddle the saw and the angled end of arm In testimony whereof I aflix my signature D to engage in registering apertures in the in presence of two Witnesses.
