SAFETY-FASTENING FOR HAMM ER- HANDLES.

SPECIFICATION formmg part of Letters Patent No. 720,297, dated February 10, 1903. Application filed October 10, 1902. Serial No. 126,796. (No model.)

To all whom it ncay concern.-

Be it knownthat I, FREDERICK STRAUB, a citizen of the United States, residing at Flat-- iron, in the county of. Lawrence and State of South Dakota, have invented a new and useful- Safety-Fastening for Tool-Handles, of which the following is a specification.

My invention relates to the manner of fastening a handle in a tool in which the handle passes through an eye in the tool; and the object of my improvement is to supply a safety-fastening which will prevent the said handle from slipping out of the eye of said tool. I attain this object by means of the simple device illustrated in the accompanying drawings, in which- Figure 1 is a side View of a handle in a tool, showing my safety-fastening applied; and Fig. 2 is a cross-section of the handle with the safety fastening applied. Fig. 3 is a short bolt and nut. Fig. 4 is a rod. Fig. 5 is a clamp made to embrace the tool-handle. Fig. 6 is an end View, and Fig. 7 is a side view, of a tool-eye.

As will be seen, my device consists of three separate parts, and, as illustrated, A is a short bolt with a not by means of which the rod B is attached to the clamp C. The manner in which they are attached to the tool and handle'is plainly set forth in the drawings, and maybe described as follows: In the side of the tool a hole is first drilled through from the outside into the opening in the tool made for the handle, commonly called the eye, and countersunk, (marked fin my drawings.) Parallel with the handlea groove is also cut in the tool to connect this hole f with the outside portion of the tool, this groove being in the side of the eye and is marked e in the drawings.

The rod B consists of a stout wire and has one end at bent at right angles and the other end I) bent intoan eye with an opening at right-angles to the end a sufficiently large to pass the bolt A through, which is then fastened to the tool by passing the end a through the hole f from the inside outward and allowing the wire to then nest along the groove 6 in the side of the too1-eye. In this position then the end I) is outside the tool.v The handle is now driven into the tool and wedged, as is commonly the custom.

The clamp C is made to embrace the toolhandle, as in Fig. 1, and the ends bent upright until the openings cl and d are in a straight line with the eye 19. Through all of said openings the bolt, Fig. 3, is inserted, and the parts are drawn together by means of a nut, which securely fastens the clamp to the handle.

I am aware that prior to my invention handles have been fastened to tools by driving them in and Wedging the handle in the eye of the tool. I therefore do not claim this combination; but

What I do claim as my invention, and desire to secure by Letters Patent, is

The combination with a tool handle and head, of a clamp embracing the tool-handle and a wire secured at one end to the clamp and the other end bent to enter a hole in the head.

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

FRED. STRAUB.
