Abstract

A cartridge dispensing gun comprises a pusher mechanism for incrementally displacing a dispensing piston of the cartridge, said pusher mechanism comprising a pusher rod (4) incrementally advanced by actuation of a trigger to tilt and displace a gripper associated with the rod. The gripper is forme d by two or more gripper plates (16) mounted in parallel, and each having a passage through which the rod passes. The passage in the gripper plate is bounded at one side of the gripper plate by an arc of part-circular shape to define a part-circular edge which grips the rod when the gripper plate is tilted upon actuation of the trigger and also by a surface which is inclined to the axis of the passage and which contacts the surface of the rod when th e gripper plate is tilted to thereby restrict the extent to which the edge can penetrate into the rod and cause damaging scoring of the rod.

Claims (10)

1. A cartridge dispensing gun comprising a pusher mechanism for incrementally displacing a dispensing piston of the cartridge, said pusher mechanism comprising a pusher rod incrementally advanced by actuation of a trigger to tilt and displace a gripper associated with the rod, the rod being at least partially of substantially circular cross-section, said gripper comprising a plurality of gripper plates mounted in parallel, each gripper plate having a passage through which the rod passes, the passage in the gripper plate being bounded at one side of the gripper plate by an arc of part-circular shape to define a part-circular edge which grips the rod when the gripper plate is tilted upon actuation of the trigger and also by a surface which is inclined to the axis of the passage and which contacts the surface of the rod when the gripper plate is tilted.
2. A cartridge dispensing gun according to claim 1, wherein said surface is a part-cylindrical surface which corresponds to the surface of the rod whereby the adjacent part of the rod is cradled by the said surface when the plate is tilted.
3. A cartridge dispensing gun according to claim 1, wherein said surface is defined by a series of mutually inclined flats whereby the adjacent part of the rod is cradled by said surface.
4. A cartridge dispensing gun according to any one of claims 1 to 3, wherein each said plate has two such part-circular edges spaced by said surface.
5. A cartridge dispensing gun according to any one of claims 1 to 4, wherein the plates are mounted in face-to-face contact and a permanent lubricating coating is applied to at least one of said contacting faces to facilitate slippage between the contacting faces when the plates are tilted.
6. A gripper plate for use in a pusher mechanism of a cartridge dispensing gun to incrementally advance a pusher rod of the mechanism upon tilting of the plate and displacement of the plate in the longitudinal direction of the rod, said plate comprising a passage for receiving the rod, a gripping edge adjacent the passage and operative to grip the rod when the plate is tilted, and a surface adjacent the passage to contact an adjacent surface of the rod when the plate is tilted whereby to restrict the depth to which the gripping edge can penetrate into the surface of the rod.
7. A gripper plate according to claim 6 for use in a pusher mechanism having a pusher rod of substantially circular cross-section, wherein the said surface of the plate is of substantially part-cylindrical form of a diameter corresponding to that of the pusher rod.
8. A gripper plate according to claim 6 or claim 7, wherein the gripping edge extends over two arcs separated by the said surface of the plate.
9. A gripper plate according to any one of claims 6 to 8, wherein the plate is stamped from carbon steel and then heat treated.
10. A gripper plate according to any one of claims 6 to 9, wherein at least one surface of the plate has a lubricant coating to permit slippage between two like gripper plates operating in parallel on the pusher rod.
