Abstract
A pincer-like tool for attaching a selected slotted plastic head to the shank of a key and for detaching the head therefrom. The tool has a pair of pivotally connected members, one of which provides the body of the tool and has opposite flat-surfaced sides, each of which is designed to receive and hold a slotted plastic head in position to have the shank of a key forced into its slot or expelled therefrom -- depending upon which of the two sides of the body the head is placed on -- by the advance of a carriage that is slidably mounted on the body; the other one of the pivotally connected members being a short and long armed bell crank lever having its short arm drivingly connected with the carriage and its long arm overlying a handle on the body to form a pair of pincers which, upon being gripped and squeezed together, advance the carriage.
Claims14
A tool for attaching a slotted head to or detaching it from the head end portion of the shank of a key, comprising:
- A. a body having an upwardly facing head-supporting surface with an abutment rising therefrom to receive and support a head with its slot parallel to said supporting surface and perpendicular to said abutment;
- B. a carriage slidably mounted on the body, said carriage having a longitudinal axis, an upwardly facing key shank supporting surface and a front end facing said abutment;
- C. means constraining the carriage to linear advance along a path parallel to its longitudinal axis towards and retraction from said abutment;
- D. key shank engaging means on said carriage by which the shank of a key laid on its upwardly facing surface is held and positioned on the carriage with its head end portion protruding beyond the front end of the carriage in line with the slot of a head in position on the upwardly facing head-supporting surface of the body in front of said abutment, so that as the key shank is advanced by the carriage its protruding head end portion is driven into the slotted head;
- and
- E. manually operable motion-producing means reacting between the body and the carriage for advancing and retracting the carriage.
