Abstract
The present invention relates to a tool (10) used for the removal of retained spring clips on railway tracks. The tool is characterized by a body (12) and a handle (14), the body having clip engaging means (22) adapted to engage outer edges of a retained clip and the handle including means (24) capable of delivering an impact to the body, the clip engaging means being adapted to compress the outer edges of the clip so as to permit passage of the clip through a gate retaining the clip to thereby release the clip. The invention also discloses a protective shroud (30) used to protect an operator of the tool from injury caused by movement of the clip when released.
Claims11
A tool useful for removing a spring clip retained on a rail track by having outer edges of the clip retained outside of a gate, the tool including:
- a body having a recess formed in the front face thereof, the recess serving as clip engaging means, and a bulbous portion extending rearwardly from a lower end of the body, said bulbous portion being adapted to bear against an inner surface of the rail track;
- and
- a handle including an impact hammer, said impact hammer comprising an open ended tube located around the handle and slidable over a longitudinal axis of the handle to thereby deliver an impact to the body, the clip engaging means being adapted to engage and compress outer edges of the clip in response to an impact delivered to the body from the impact hammer so as to permit passage of the outer edges and body of the clip through the gate to thereby release the clip;
- and
- the tool further including a shroud attached to the tool and located so as to pass over the clip and the body to protect the operator of the tool.
A method of removing a spring clip retained on a rail track by having outer edges of the clip retained outside of a gate, the method comprising steps of:
- providing a tool having a body and a handle, the body having a recess formed in the front face thereof, the recess serving as a clip engaging means, and a bulbous portion extending rearwardly from a lower end of the body, said bulbous portion being adapted to bear against an inner surface of the rail track, the handle including an impact hammer, said impact hammer comprising an open ended tube located around the handle and slidable over a longitudinal axis of the handle to thereby deliver an impact to the body, the clip engaging means being adapted to engage and compress outer edges of the clip in response to an impact delivered to the body from the impact hammer so as to permit passage of the outer edges and body of the clip through the gate to thereby release the clip, and the tool further including a shroud attached to the tool and located so as to pass over the clip and the body to protect the operator of the tool;
- engaging the clip in the recess formed in the front face of the tool;
- and
- delivering an impact to the tool with the impact hammer to thereby engage and compress the outer edges of the clip so as to permit passage of the outer edges and body of the clip through the gate to thereby release one clip, the shroud serving to limit the travel of the release clip and protect the operator from the clip.
A tool for removing a retained spring clip comprising:
- a body having clip engaging means adapted to engage outer edges of a retained clip;
- and
- a handle including means capable of delivering an impact to the body, the means capable of delivering an impact including an impact hammer having an open ended tube located around the handle and slidable over a longitudinal axis of the handle to thereby deliver an impact to the body, the clip engaging means being adapted to compress the outer edges of the clip in response to an impact delivered to the body from the handle so as to permit passage of the clip through a gate retaining the clip to thereby release the clip.
