Abstract: A process for assembling a hand tool includes the steps of heating an elongated tang element fixed relative to the tool head, aligning a front end of a composite tool handle with a rearwardly extending portion of the tang element, and driving the heated tang element into the tool handle. The tool handle includes a thermoplastic section in proximity to the front end thereof, having an elongate tang receiving channel. The heated tang element is driven into the tang receiving channel such that as the tang element engages the tool handle, the thermoplastic section surrounding the tang receiving channel is softened and flows into intimate contact around the tang element and then hardens as the heat of the tang element is dissipated to hold the tang element in place. In one preferred form, the tang element forms a portion of the tool head which is heated and then positioned in a stationary jig.

Abstract: A replacement tool handle for a percussive tool includes a high strength, load-bearing rod which is inserted through the eyehole of a tool head from its upper end, a grip which ensheathes a portion of the rod projecting from a lower end of the tool head, and two interlocking members which fasten the grip to the rod. The rod includes a handle shaft capable of passing completely through the eyehole of the tool head, and a shaft retainer located at a first end of the shaft for preventing an adjacent end of the rod from passing through the eyehole. The shaft retainer forms a generally frusto-conical slug having an outer surface portion generally corresponding to a portion of the eyehole, an enlarged portion which is incapable of passing through the eyehole, and an inner cavity in which the first end of the shaft is secured. Both the handle shaft and an internal cavity provided the grip have non-circular cross-sections to prevent turning of the grip relative to the shaft.

Abstract: A tool such as a sledge or an axe is fastened on a handle by an adhesive which expands as it solidifies. A flexible sleeve is fitted on the handle and has a flange which is disposed at the lower end of the end portion of the handle that projects into the usual bore in the head. The flange closes the bottom of the bore and the sleeve includes an upwardly projecting extension which engages the lower end of the wall of the bore so that the flange and the extension locate the head properly on the handle in both the horizontal and vertical planes. The end portion of the handle which projects into the bore of the head is smaller in cross section than the bore to leave a space between this end portion and the wall of the bore and this space is filled with an adhesive which is liquid when it is poured into the base but which expands as it solidifies to provide a firm connection between the handle and the head.
