TOOL RETAINER Filed Aug. 22, 1928 7 o Inventor IT M. Coffman p mm A itorney Patented Oct. 22, 1929 UNITED STATES PATENT OFFICE JESSE MARION GOFFMAN, OF VACAVILLE, CALIFORNIA TOOL RETAINER Application filed August 22, 1928.

This invention appertains to improvements in tool attachments, and more particularly to a novel retainer especially adapted for supporting tools on inclined surfaces, for

example, when in use upon houses constructed with inclined roofs. In such instance, the attachment may be extended and urged against the roof (especially in the case of wooden shingled roofs), to bite into the roof material and prevent the gravitation of the tool away from the working position.

The principal object of the invention is to provide a retaining attachment of the ob aracter mentioned, capable of being applied to tool handles of conventional makes.

Another object of importance is to provide a retainer for tools wherein the retaining elements may be collapsed for substantial concealment.

These and other objects of the invention will become more apparent to the reader after considering the invention as described and claimed hereinafter.

In the drawings Figure 1 represents an edge elevation of a conventional saw in retained position upon an inclined surface.

Fig. 2 represents a longitudinal sectional view through a saw handle, showing the re taining element in extended position.

Fig. 3 is a front elevation of a retainer with its retaining element in extended position.

Fig. 4 represents a rear side elevation of the retainer.

Referring to the drawings wherein like numerals designate like parts, a conventional saw blade A is provided with the usual wood on handle 13, which is provided at a suitable point with a pocket or recess 8.

In carrying out the present invention, a bushing i is provided for snug secured disposition within the recess 3. The outer end of the bushing 4: is provided with a plate 5 which extends beyond the periphery of the bushing at all points thereof. The plate 5 is substantially square, and is provided with a slit 6 extending inwardly from the edge thereof and terminating at substantially the center of the plate.

Serial No. 301,399.

The plate is formed with openings 7 for receiving suitable securing elements, whereby the plate may be secured to the handle.

A pin 8 is disposed transversely within the bushing a for pivot-ally mounting a tooth 9, the same being reduced at its outer end portion 10 and pointed at its extremity 11. A spur 12 is disposed laterally at the outer end portion of the tooth.

he inner end of the tooth is provided with a concavity 13 in which the leaf spring 1 lis tensionally engaged for retaining the tooth in the extended position shown in Fig. 2. The leaf spring is secured at one end to the bushing 3, while its opposite end portion is free and always tensionally engaged against the inner end portion of the tooth.

Obviously, this novel retainer may be applied to tool handles of practically any design, and furthermore, certain changes in the specific shape, size, and materials may be resorted to in the manufacture of this device without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described the invention, what I claim as new is 1. A tool retainer comprising a pivotal tooth mounted upon a tool, means for maintaining the tooth in extended position, and a laterally projecting spur on said tooth.

2. A tool retainer comprising a pivotal tooth mounted upon a tool, means for maintaining the tooth in extended positions, the outer end portion of the tooth being reduced and pointed at its extremity, and a laterally s5 projecting spur on said tooth at its pointed extremity.

3. A tool retainer comprising a tooth pivotally connected adjacent one end to a tool handle and being pointed at its opposite end 9 and adapted to be positioned so that the pointed end will project outwardly from the tool, and a laterally disposed spur adjacent the end of the tooth.

4. A tool retainer in combination with a tool handle formed with a recess; a bushing,

a plate at one end of the bushing provided with a slit therein, and adapted to be secured to the tool handle, said bushing being adapted for disposition within the recess of the handle, and a pivotal tooth pointed at one end and being adapted to have its pointed end disposed through the slit, the plate at one end thereof being adapted to stop said tooth in a ppsition substantially at right angles to the p ate.

5. A tool retainer in combination with a tool handle formed with a recess; a bushing, a plate at one end of the bushing provided with a slit therein and adapted. to be secured to the tool handle, said bushing being adapted for disposition Within the recess of the handle, and a pivotal tooth pointed at one end and being adapted to have its pointed end disposed through the slit, the plate at one end thereof being adapted to stop said tooth in a position substantially at right angles to the plate, and tensional means for maintaining the tooth in the aforementioned position.

6. A tool retainer for tools having handles wherein the handle is provided with a recess .a plate provided with a slit portion for dis position over, the'recess, a tooth pivoted at one end to the handle and within the plate to stop the tooth at an extended position by the engagement of the latter against the plate at one endoof the slit.

7 A tool retainer for tools having handles wherein the handle is provided with a recess; a plate provided with a slit portion for disposition over the recess, a tooth pivoted at one end to the handle and within the plate to stop the tooth at an extended position by the engagement of the latter against the plate at one end of the slit, the inner end of the tooth being provided with a concavity, and a leaf spring arranged within the recess of the handle for tensional engagement within said concavity.
