TOOL HEAD SECURING MEANS Filed July 26, 1926 Patented Nov. 3, 1931 UNITED STATES} 'WILLIAM BRAVERMAN; OF CINCINNATI, OHIO moor. HEAD snonnme MEANS Application filed July 26,

This invention relates to tools and more particularly to adjustable means for attaching tool heads on handles.

In the prior art, attempts have been made 6 to attach tool heads to handles so that they will not be readily disengaged therefrom. But

for various reasons such prior art devices have been unsatisfactory, more particularly because while they serve to hold the tool head 10 on the handle rigidly, it was impossible to adjust the relative position of the tool head.

Amon the objects of this invention will be founc means for securing tool heads to handles rigidly and yet which enable the position of the tool head to be adjusted.

Other and further objects and advantages of this invention will appear from the more detailed description set forth below, taken in conjunction with the accompanying drawings wherein there is shown by way of illustration, and not by way of limitation:

In Figure 1 a tool head secured to a handle by the attaching means covered by this invention;

In Figure 2 a section on line 22 of Figure 1:

In Figure 3 a blank from which the yoke is desirably made; and

In Figure 4 a modification of the device as used in securing certain types of tool heads on handles.

WVhile this invention will be described with reference to the disclosures specifically set forth in the drawings, it will be understood that various changes may be made in these structures by those skilled in the art, without departing from the spirit and scope of this invention.

Fundamentally this invention includes means for detachably securing a tool head to the handle which means include a yoke surrounding the tool handle holding adjustable means engaging the tool head, so that by arrangement of the adjustable means, the tool head is held in position adj ustably yet rigidly. The means disclosed for holding tool head 2 on handle 1 include a yoke 3 surrounding the tool handle near the usual bulge thereon generally found just below the helve of the handle. As shown in Figure 3 this yoke is de- 1926. Serial No. 125,047.

sirably made to form a body portion carrying an enlarged portion 4 centrally located on the strip body of the yoke blank, this portion 4 ultimately forming an apron. The ends of the body of the yoke proper are formed with right angular portions 5, 5 carrying perforations 7, 7. The right angle members 5,5 are adapted to be bent outwardly from the body portion of the yoke and to lie one above the other so that the perforations 7, 7 aline. The perforations are adapted to receive the 1 screw 6 carrying the usual threaded end. As

shown in Figure 1 the tool head, being in this instance a hammer head is formed with the lug 8 desirably integral with the hammer head. This lug 8 is provided with a tap 9 threaded to receive the threaded end of the screw 6.

As shown in Figure l the parts are readily assembled by bending the yoke about the handle 1 just below the helve so that it lies adjacent to the bulge on the handle, with the right angle members 5, 5 extending outwardly and overlying each other. The screw 6 is inserted through the perforations 7, 7 and is screwed into the threaded hole 9 of the lug 8. By tightening up the screw member 6 the tool head 2 is rigidly secured to thehammer handle, but due to the fact that a screw mem ber is used, the parts may be adjustably positioned. This is particularly desirable when wear of the parts necessitates adjustment.

In place of having the lug 8 integral with the tool head, it may obviously be made of a separate piece of metal which is then attached to the tool head in any desirable way. This may be done, for example, by providing the lug 8 with a projection which fits an opening in the tool head adapted to receive the projection.

In certain types of tool heads it is unnecessary to use a lug since the opening 9 may be made in the tool head itself. This is illustrated in Figure 4 where a threaded opening 9 is made in the tool head itself into which the screw 6 may enter directly.

While the yoke 3 has been shown as provided with an apron 4 for strengthening purposes, obviously the apron may be omitted.

Having thus set forth my invention, I claim:

1. In combination, a tool head carried on a handle, and means for adjustably securing the tool head on said handle comprising a threaded aperture in the tool head, a yoke on said handle near the helve thereof provided with perforated ears and also carrying a reenforcing apron oppositely positioned with respect to the ears, a screw passing through said perforated ears and engag ng the threaded opening in the tool head whereby the tool head may be tightened on the:

helve of the handle after the head has become loose on said handle through use.

2. A blank adapted for making a yoke to hold attaching-means for securing a tool head on a handle, comprising an elongated strip of sheet metal carrying an enlarged portion centrally located on one side of said metal strip, said strip also carrying at each end thereof angled portions adapted to form ears, the plane of the .ear forming portions being angularly disposed with respect to the longi-' tudinal axis of the handle.

3. In combination, a tool head carried on a handle provided with a helve, a threaded I opening in said tool head, a yoke on said handle near said helve, said yoke being provided with perforated cars, a screw passing through the perforatedears to hold said ears together and to cause the yoke to embrace the handle, said screw passing into the threaded opening in the tool head whereby '1 when the head through use becomes loosened on said handle the screw may be advanced further into the threaded opening to tighten the head on the handle. f

In testimony whereof I hereunto afiix my signature.

WILLIAM BRAVE AN,
