ROBERT W. HARDIE, OF ALBANY, NEW YORK.

HANDLE-FASTENER.

SPECIFICATION forming part of Letters Patent No. 255,166, dated March 21, 1852.

Application filed November 3, 1881.

To all lwhom it may concern:

Be it known that I, ROBERT W. HARDIE, a citizen of the United States, residing at Albany, in the county ot' Albany and State ot` New York, have invented a new and useful Improvement in Handle-Fasteners, ot' which the following is a specification.

My invention isa handle-fastener; and it consists ot' a certain speeilic device, the construction and arrangement ot' the parts ot' which are hereinafter fully set forth, and particularly pointed out in the claim.

In the accompanying drawings, Figure l represents the device applied to a hammer, in which a longitudinal section of the fastening in place in the hammer is shown. Fig. 2 shows a side elevation of the handle and the fastening device with the hammer in longitudinal section, the device being in position ready for application to the hammer. Fig. 3 shows dit'- ferent views 0f the locking-keys.

In these drawings, the eye of the hammerA is shown as flaring outwardly. The handle/B is formed with a reduced end, E, and shoulders e e; hut the dimensions of the handle at the widest part ofthe shoulders e e are not larger than the smallest part ot` the eye, so that the handle may he pushed through the eye into a position shown in Fig. 2, in which the shoulders comealittle outside ofthe outer surface ot' the hammer. Plainly, the shoulders may project only so far as to he Hush with that surface, or may remain a little inside, it heilig only necessary that the handle shall project far enough to permit the application of the wedging or locking piecesff. These piecesf fare made with one side sloping or inclined to the axis of the handle and the other substantially parallel therewith, the pieces fitting to the reduced end ot' the handle, which, when the handle is in place,is within the tool. These pieces are also provided with teeth or projections t t, which fit into corresponding notches Vand perfectly.

| in the reduced end of the handle. When they are in place upon their sides on saidreduced end they are litted exactly to the eye, so that when driven into the eye with the handle in the position shown in Fig. l they tit snugly When in such position it will he obvious that the centrifugal l'orce arising from the delivery of the blow will only tend to' wedge the tool upon its handle more tirmly,sol that the tool cannot fly oit', even if the handle be not tightly fitted in the eye. Thehandle may he easily removed by driving it outward through the eye into the position shown in Fig. 2.

I am aware that handles have been wedged in various ways, and that wedges with roughened or serrated faces hearing upon the wood ofthe handle have heen driven hy the side of the handle, the reduced end of the handle being slopedto admit the wedge, and I do not broadly claim anysuch construction, the essential principle ot` my invention being limited t0 a handle which is passed through the eye, with a wedging or locking piece provided with a projection or tooth placed against it, and wedged by drawing or driving hack the handle into its place in the eye. I desire only not to be limited to the'use ot' two of the pecesf f, as a single one may be sufficient.

What I claim is- A 'handle-fastener consisting of the notched handle adapted to be inserted through the eye and to project therefrom at the outer side, the locking wedge piece or piecesf, titted thereto, in combination with the daring eye of thetool, whereby when the parts are all in place the centrifugal force is lnade to wedge the tool upon its handle, substantially as described.
