PATENT OFFICE.

CADILLAC, MICHIGAN.

SPECIFICATION forming part of Letters Patent No. 227,057, dated April 27, 1880. Application filed March 5, 1880. (No model.)

To all whom it may concern Be it known that I, LEVI HENRY ROBERTS, of Cadillac, in the county of Wexford and State of Michigan, have invented a new and useful Improvement in Fastenings for Tool- Handles, of which the following is a specification.

Figure l is a side view of the improvement, partly in section, through the line as m, Fig. 2. Fig. 2 is a cross-section taken through the line 3 y, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to secure handles to tools in such a manner that the handles will be held in place firmly and securely, and

quickly.

The invention consists in a fastening for tool-handles, formed of a plate roughened upon one side and smooth upon the other, and a key, which plate and key are inserted between the rear edge of the handle and the rear edge of the tool-eye, as will be hereinafter fully described.

I will describe the improvement as applied to axes, but do not limit myself to that use, as it can be applied to picks, hammers, and other tools with equal advantage.

In the drawings, A represents an ax, and B a handle. The eye 0 of the tool A should be made without any bulge in its middle part, and should taper from rear to front, as shown in Fig. 2. The forward edge of the eye 0 may be fiat, as shown in Fig. 2, or rounded, as may be desired. The rear edge of the eye C may have a groove formed in it, as shown in Fig. 2, or may be made fiat, or may be rounded, as may be desired. The end of the handle B should fit the eye 0 snugly; but a space should be left along its rear edge to receive the plate D and key E. The rear edge of the end of the handle B should be flattened to receive the plate D. The inner side of the plate D should be roughened to prevent it from slipping upon the handle B; but its outer side should be smooth. The inner side of the key E should be made smooth to fit upon the plate D, and its outer side should be so formed as to fit the key-seat in the rear edge of the eye 0. The plate D and key E should be made longer than the eye 0, so that their rear ends may serve as braces to the handle B, as shown in Fig. 1. The key E should be made of such a size that when driven firmly into place its forward end may project far enough to receive a blow to start it back when it is to be removed, after which it may be driven out by means of a punch, spike, or other suitable can be attached and detached easily and? eans. With this fastening the handle B will be held firmly and securely without being weakened by wedgin g, and can be easily and quickly attached and detached, as required.

Having thus described my invention, I claim as new anddesire to secure by Letters Patent 1. An improved fastening for tool-handles, constructed substantially as herein shown and described, consisting of the plate D, roughened upon one side and smooth upon the other, and the key E, to adapt them to be inserted between the rear edge of the handle and the rear edge of the tool-eye, as set forth.

2. The combination, with the tool A and the handle B, of the plate D, roughened upon one side and smooth upon the other, and the key E, substantially as herein shown and described, whereby the handle will be secured to the tool A firmly and detachably, as set forth.

LEVI HENRY ROBERTS.
