Claims
- 1. A tool for applying wedges in slot keys overlying windings retaining slots in a rotor body of an electric machine wherein the slot keys have at least one spring element for biasing the wedge in the slot key into high-pressure, efficient electrical contact with the rotor body, comprising a lever having a main arm and a pair of dogs carried by said lever adjacent an end of said main arm, one of said dogs shaped for disposition in the slot keys and the other dog shaped to overlie the slot keys whereby pressure applied to said main arm, with the one dog in a slot key and the other dog overlying the slot key, applies pressure to said dogs in opposite directions, thereby fixing the lever at a predetermined axial position along the slot key, and a second arm pivotally carried by said lever and carrying a head for engaging the wedge whereby, upon fixing the lever at a predetermined axial position along the slot key, the second arm may be pivoted to advance a wedge along the slot key.
- 2. Apparatus according to claim 1 wherein one of the dogs is pivotally connected to said main arm.
- 3. Apparatus according to claim 1 wherein said one dog is pivotally connected to said main arm for rotation about a pair of axes disposed at right angles to one another.
- 4. Apparatus according to claim 1 wherein the pivot axis of said second arm lies to one side of the dogs.
