Patent CA-2337563-A1 (CA)
Title: Capped head hammer
Inventor: JEROMINSKI TED
IPC: B25D1/02
Filed: 2001-02-19
Abstract: A hammer including a hammer head with an end pole and a cap providing a selected type of cap impact face for the hammer head. The cap forms a chamber and the pole is removably slidably fitted into the pole chamber. A fastening cross-pin removably secures the cap to the pole and also allows the pole to move relative to the cap in the longitudinal dimension between an impact mode position of the cap impact face against a workpiece and a static mode position of the cap impact face remote from the workpiece. A biasable pad for absorbing shock is positioned within the chamber formed in the cap between the cap impact face and the pole. The biasable pad absorbs shock to the hammer head during the impact mode and also returns the pole from the impact mode position to the static mode position by self-biasing action. The fastening cross-pin extends through the pole pin hole and is threadably connected to one of the cap side walls and press-fitted to the other cap side wall. The fastening cross-pin is in contact with the front surface of the pole pin hole in the static mode and moves to a free position in the pole pin hole in the impact mode so that the cross-pin avoids shear during the impact mode. Alternatively, a retaining means may be employed to hold a fastening cross-pin, such as a roll pin that holds a removable cap mounted to a pole of a hammer, thus providing a selected type of cap impact face for the hammer head. The fastening cross-pin is removably positioned in cap pin holes in the cap cylindrical wall and to a pole pin hole so as to removably secure the cap to the pole. The fastening cross-pin extends through the pole pin hole and is connected to the cap side walls. One type of retaining ring is externally expansive and is set into an external groove around the cap that is aligned with both ends of the cross-pin; and another type is an internal expansion retaining ring that is also the fastening cross-pin that is biased against the pin holes in the cap cylindrical wall.
