TOOL-HANDLE.

Specification of Letters Patent No. 29,622, dated August 14, 1860.

To all whom it may concern:

Be it known that 1, JOHN G. Booms, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Mode of Attaching Handles to Picks and other Tools; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a side View of a pick having its handle attached to it according to my invention, the handle being partly in section. Fig. 2 is a section of the pick and handle, taken in the line a m, Fig. 1. Fig. 3 is a transverse section of the same, taken in the line y, y, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improved mode of attaching handles to that class of tools and implements which are generally provided with eyes to receive the handles.

The object of this invention is to dispense with the use of eyes which greatly weaken the tools, and at the same time obtain a firm and durable connection and one that will admit of a ready adjustment of the handle to the tool and its detachment therefrom.

' To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A represents a pick which may be of the usual shape or form, but not having the usual eye at its center, the pick being solid its whole length.

To the under side of the pick A, at its center there are attached two straps B, B, which project from the pick at nearly right angles, and in a plane which bisects the pick longitudinally. The inner surfaces of the straps B, B, are planes, and between them one end a, of the handle O, is fitted, said end a, being of rectangular form and provided with a tenon b, at its extreme end, which tenon b, fits within a recess 0, in the pick between the two straps.

In the handle C, a steel pin or rod 03, is

fitted transversely. The ends of this rod project beyond the sides of the handle and fit within holes 6, in the inner sides of the straps 'B.

D, D are two metal bands which are driven on the straps B, B, and clamp firmly the straps and handle together.

The holes 6, in the straps B, are made slightly oblique or out of line with the rod d, so that when the bands D, D, are driven on the straps, the rod d, and holes 6, will draw the tenon b, at the end of the handle snugly into the recess 0, in the pick.

By this arrangement a very firm and stiff connection of the handle and tool is obtained and the tool is extremely strong, not being weakened by an eye, nor rendered difficult to forge, as the straps B, B, may be forged on the tool, in equally as short a time as making a well formed eye. The steel rod cl, is an important feature of the invention, as it not only prevents a longitudinal displacement of the handle, but also causes the handle to be drawn snugly and firmly into proper position.

The bands D, D, prevent any racking or working of the handle between the straps as the pick is used, and keep the handle and straps firmly in contact.

It will be seen that in case of the breaking of a handle the broken one may be readily detached and replaced by a new one.

I do not claim broadly the attaching of a handle to a pick or similar tool, without an eye, for that has been previously done; but

I do claim as new and desire to secure by Letters Patent The attaching of the handle C, to the pick A, or other tool by means of the straps B, B,

bands D, D, and the steel rod cl, placed transversely. in the handle O, and having its ends projecting from the handle and fitting in the holes 6, in the straps, substantiallyas described.

JOHN G. ROGERS.
