TOOL HANDLE.

Application filed August 31, 1921.

To all whom it may concern:

Be it known that I, Josnrn V. VVooD- wonrrr, a citizen of the United States, and resident of Camp Kearney, county of San Die o, and Eitate of California, have invented a new and useful Tool Handle, of which the following is a specification.

The present invention relates to improvements in tool handles and is particularly designed to be used in connection with files or similar tools. Its principal object is to provide an all metal handle for files adapted to he slipped on the shank of the same and to be firmly held there by a certain spring action imparted to the handle by its peculiar construction. While in the following description I am going to refer to my handle in connection with files only, I.

do not wish to be understood as confining myselfto that tool, but seek protection on the idea expressed in this particular embodiment wherever it can be used to advantage.

l attain the object set forth preferably by the mechanism illustrated in the accompanying drawing, in which Figure 1 represents a side View of my handle having a file secured therein, Figure 2 another side view of the same taken at right angles to the first view, Figure 3 a longitudinal section through the same along line 3-3 of Figure 1, Figure 4 a cross-section through the same along line 1-4 of Figure l, and Figure 5 a side view of the handle detached from the file.

Referring to the drawings in detail, the shank 1 of the file 2 is inserted into the handle The latter consists of a plain strip oi? metal curved so as to present a substantially semi-circular cross-section and bent upon itself so that corrresponding semicircular cross-sections form a full circular cross-section. Where the metal is bent on itself a part of the metal is cut out, as shown at 4:, to ease the strain on the metal. The original strip of metal may be of varying shape, it may be rectangular, in which case the final shape of the handle will be tubular or it may be cut with a wide central part, decreasing in width toward either end and increasing again at either end so that the handle will have the shape shown in the drawing, which is somewhat more convenient in its use. The particular shape Serial N 0-. 497,193.

of the handle is not essential, the principal point being that my handle is longitudinally divided and that through the common head a certain spring action is imparted to the two halves having a tendency to press them apart.

The shank of the file is secured in this handle by means of deflected portions of the handle. As will be seen from the drawing, each semi-circular section of the handle has a plurality of portions 8 which are separated from the main body by slits extending cross-wise over said section and are deflect ed from the general outline of the main body by being depressed so as to extend beyond the base of its section into the other section. Since both sections are provided with these deflected portions there is a central space in the handle defined by said deflected portions adapted to receive the shank of the file, when the two sections are pressed together and to firmly hold the shank when the pressure on the sections is released. It will be seen that in this manner a handle is provided that is easily slipped on the tool shank, that firmly holds the same and that may be used again after it has been removed because the removal does not in any way afi'ect its effectiveness.

1 claim:

1. In a tool holder, an integral expansible spring handle having spaced opposed side portions and ends to receive a tool shank therebetween, and means projecting inwardly from said portions past the axis of the handle in side by side relation for engaging said shank, when said portions are compressed, on the side of the shank remote from the side of the handle which carries the projecting means, whereby when said compressed portions are released said pro jecting means will automatically grip the shank.

2. In a tool holder, an integral expansible spring handle having spaced sides to receive a tool shank therebetween, and apertured shank receiving elements projecting inwardly from the respective sides in overlapping relation to receive a tool shank when said apertures are caused to register by the compression of said sides and to automatically exert a grip on. said shank when said sides are released.
