SPECIFICATION forming part of Letters Patent No. 285,990, dated October 2, 1883.

' Application filed August 27, 1883. (No model.)

To all 'whom it may concern Be it known that I, JOSIAH F. FRnNcr-r, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Tool-Handles, of which the following is a specification.

My invention relates to handles for files and other tools which are provided with tangs for introduction into wooden handles; and the object of my invention is to provide a handle, and to so prepare a tang for the same, that the former may be more securely fastened to the tool than by driving the tang into an ordinary wooden handle.

In the accompanying drawings, Figure 1 is a sectional view of the improved tool-handle secured to the tang of a file or other tool; Fig. 2, a view of the tang as it appears when detached from the handle; and Fig. 3, a trans verse section onwthe line 1 2, Fig. 1.

In carrying out my invention, it is not essential to alter the general tapering form of the tang a of the tool, for it. should be such that while it is threaded for application to a special handle, it could, in the absence of the latter, be driven into an ordinary handle. I

out on the tang a screw-thread terminating in one direction at a short distance from the point where the tang meets the body A of the file or other tool, the thread being continued in the opposite direction to about the extent indicated in the drawings. A metal tube or nut, D, closed at its rear end, (i, is driven tightly into the wooden portion Bof the handle, part of the tube being hexagonal, as shown in Fig. 3, or of any other shape which will-prevent it from turning in the wood. A ferrule, G, is fitted and secured to the wooden portion of the handle, the end of this ferrule being bent over the outer end of the tube D. This, however, is not essential, as the ferrule may be independent of the tube. A portion of the interior of the tube D, from the outer end of the same to about the point x, is threaded to accord with the thread on the tang. The handle is screwed onto the tang until the extreme end of the latter is arrested by the closed end d of the tube D, a central recess, f, being preferably made in the latter, so that the proper position of the handle on the tang in line with tool may be assured.

the body of the It Will be seen that in screwing the handle to its place the wooden portion is entirely relieved from all end strain, the closed end of the tube being the abutment for the end of the tang.

Any tool having a tang or stem constructed for attachment to an ordinary wooden handle may be prepared for the special handle described by cutting on the tang or stem, near its junction with the body of the tool, ascrewthread, the tube being of course made of such length that its closed end shall always form an abutment for the end of the tang.

I have shown in the present instance a tapering tang, a portion of which is threaded, the terminal portion being plain. This I dis claim, as the form of tang is substantially similar to that which forms the subject of an applicatio n for a patent filed by me August 27, 1883, Serial N 0. 104,858. It should be understood, however, that while it is essential that the tang should be threaded toaccord with the thread of the tube, it is not necessary in carrying out my present invention that the tang should be of the precise form described.

The handle shown in this application has a ferrule, the end of which overlaps the end of the tube D. This feature also is here disclaimed, as it is claimed in the application filed by me August 24, 1883, Serial No. 104, 634.

I claim as my invention.

1. A tool-handle in which the portion B, of wood or other available material, is combined with a tube, D, threaded internally, and having a closed end to form an abutment for the end of a threaded tang, all substantially as set forth.

2. The combination of a file or other tool having a threaded tang with the body of the tool, and a handle having a tube, D, with an internal thread to accord with that on the tang, andhaving a closed end to form an abutment for the end of the said tang, all substantially. as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSIAH F. FRENCH.
