ADJUSTABLE FILE-HA LE.

To all whom it may concern:

Be it known that I, RICHARD citizen of the United Statesof America, and a resident of Waterloo, Blackhawkcounty, Iowa, have invented certain new and useful Improvements in Adjustable File-Handles, of which the following is a specification; I

My invention. relates to improvements in adjustable file-handles, and the object of my improvement is to provide a handle withsuitable adjustable clamp-members adapted to hold a file or similar tool,.with proper means for securing the clamp-members in a desired adjusted position. This object I have accomplished by the means which are hereinafter described and claimed, and which are fully illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my adjustable file-handle showing it as adjusted to and secured to one end of a file. F ig.2 is an enlarged detail perspective view of the wedge slideway, part of same being shownas sectioned away to better disclose the construction of its lower member. Fig. 3 is a detail perspective view of the, m0vable clamp-member ofthe file-holder. Fig. 4 is a detail View of the slideway with the said movable clamp-member seated therein. Fig. 5 is an under planview of the holder, showing the clamp-members having parallel interiorholding-facesr Fig. 6 is an under plan view'of a holder wherein the inner holding faces of the clamp-members have their lines .of direction inclined to each other.

Similar letters refer to similar parts throughout the several'views.

. The handle a is socketed at one end to re ceive a sleeve 6, the latter holding. the shankpiece 0 which is secured to the upper rear part of the slideway f by means of a screw d. The slideway f is composed .of two members separated by a space for the reception of the adjusting wedge the .members'being connected on. one side only by separated connections. The upper member f has a vertical threaded orifice toreceive a set-screw e, the latter adapted to have its lower end engage the upper surface of the wedge g when screwed down against it. The lower member of. said slideway has a transverse slot 8 to receive the movable member 'w,such lower member having parallel abutments 7c and m with inward slopin sides to coincide with the sloping sides of said movable member.

, Specification of Letters Patent. 1 Application filed January 20, 1908. Serial No. 411,864.

A. BACON, a

Patented Dec. 1, 1908.

The abutments are connected by a bar m.

The slot 8 is used to receive the movable member w, the latter being adjustable transversely therein in the slideway-body f.

- As shown-in Fig. 3 the movable member to. has on its 'under surface a projecting clamp-member '0 spaced away from and adjustable relatively to the oppositely placed fixed clamp-member y, the latter being the whole of which the middleconnection 00 forms a part. i The movable member w has two separated upwardly-projecting longitudinal clips 71 and n having inwardly converging. inner faces, the space between said faces colnciding with part of the space between the fixed members 1 and 7c, and adapted to receive the wedge g.

In Fig. 5 the clamp-members y and 0 have parallel inner faces to receive any body with parallel sides, while Fig. 6 shows a modification wherein the inner faces of the clampmembers if and 70 are adapted to grasp a body having converging sides, such as the rat-tailed file h shown in'Fig. 1. Any other tool, such as a scraper, maybe held by said means, when of suitable form to be received by'the clamping-members, but I do not intend to be understood as limiting my invention to any particular configuration of the inner faces of the clamping-members, since such faces may be varied to conform to the outer. shape of the body to be held between them.

When the movable member w has been introduced within the slot .9, and the wedge 9 within the inner space between the upper and lowermembers of the holder and the coinciding space between the clips 2' and 12., after a body such as the file h has been introduced between the clamping-members y and 0, the movement inward of the wed e causes it to, by its contact with both the clip 2' and the inner portion of the connection between the upper and lower members of the slideway f, draw the clamping-members y and 0 together thus causing the latter to exert a clutch on said file, in which position the clamp-lnembers are secured and held in place by screwing down the set-screw 6 upon the upper surface of said wedge. A slight rotation of the set-screw in the reverse direction, permits the easy displacement of the wedge, thus releasing the clutch of the clamping-members upon the body held between them.

Having described my invention What I claim as new, and desireto secure by Letters Patent, is

1. An adjustable tool-handle, comprising in combination, abody having both transverse and longitudinal slideways, said body having a depending clamp-member, a clip slidable in the transverse slideway of said body and provided With a depending clanipmember, a Wedge slidable in said clip and in the longitudinal slideway of said body, and means for detachably securing said Wedge to said body.

2. An adjustable tool-handle, comprising in combination, a body provided with a pro jecting handle and having both transverse and longitudinal slideways, said body hav- RICHARD A. BACON.
