Abstract

Apparatus is provided for surrounding engagement with an associated truck collet to accommodate a plurality of collet sizes wherein a central H-shaped yoke pivotally mounts a first and second leg downwardly therefrom wherein each leg includes an inner and outer edge where the inner edge includes a first pair of aligned arcuate recesses of a first diameter wherein outer edges of the legs includes arcuate recesses of a second smaller diameter to accommodate chucks of varying diametrical configurations. A collet key member is rotatably mounted through the yoke and includes a first and second bevel gear at each end of the collet key with a handle selectively positionable adjacent each bevel gear to effect rotation of each bevel gear relative to an associated chuck or collet member.

Claims

1. A collet key stabilizer apparatus comprising in combination,

a yoke member, the yoke member including opposed terminal ends, the opposed terminal ends defined by a first bifurcated leg pair and a second bifurcated leg pair, the first bifurcated leg pair including a first leg pivotally mounted therebetween and wherein the second bifurcated leg pair includes a second leg pivotally mounted therebetween, the first leg includes a first interior surface and the second leg includes a second interior surface, the first interior surface includes a first interior surface arcuate recess and the second interior surface includes a second interior arcuate recess wherein the first and second interior arcuate recesses are aligned relative to one another and in confronting relationship when he first and second legs are in a first position with the first and second interior surfaces in confronting relationship relative to one another, and

the first and second legs each including a respective first leg exterior surface and a respective second leg exterior surface, and

a collet key assembly rotatably mounted through the yoke member to effect rotation of a collet secured between the first leg interior arcuate recess and the second leg interior arcuate recess, and

wherein the first leg exterior surface includes a first exterior surface arcuate recess and the second leg exterior surface includes a second exterior arcuate recess, the first and second exterior surface arcuate recesses are in aligned and confronting relationship relative to one another when the first and second exterior surfaces are in a second position with the first and second legs pivoted 180 degrees relative to the first position.

2. Apparatus as set forth in claim 1 wherein the collet key assembly and the elongate cylindrical shaft are rotatably mounted through a bore extending orthogonally and medially of the yoke, the elongate cylindrical shaft including a first bevel gear mounted adjacent a first terminal end of the elongate cylindrical shaft and a second bevel gear mounted adjacent a second terminal end of the elongate shaft wherein the first and second bevel gears are axially aligned with the elongate shaft and fixedly mounted thereto.

3. Apparatus as set forth in claim 2 wherein the yoke member is defined by a longitudinally aligned H-shaped yoke.

4. Apparatus as set forth in claim 3 wherein the elongate shaft includes a first shaft bore orthogonally directed through the cylindrical shaft adjacent the first bevel gear and a second shaft bore orthogonally directed through the cylindrical shaft adjacent the second bevel gear, and a handle selectively receivable through the first shaft bore or the second shaft bore selectively.

5. Apparatus as set forth in claim 4 wherein the handle includes a handle abutment orthogonally projecting relative to the handle and a handle bore spaced from the handle abutment, the handle bore including a handle spring clip lock pin receivable thereto to secure the cylindrical shaft between the handle abutment and the handle spring clip lock pin, the handle abutment spaced from the handle bore a predetermined spacing substantially equal to or greater than a predetermined diameter defined by the elongate cylindrical shaft.

6. Apparatus as set forth in claim 5 wherein the first interior surface and the second interior surface of the first and second leg are divergent relative to one another above and below the respective first and second leg interior arcuate recesses when the first and second legs are in the first position.

7. Apparatus as set forth in claim 6 wherein the first leg is pivotally mounted to the H-shaped yoke between the first bifurcated leg pair adjacent a first leg upper terminal end and wherein the second leg is pivotally mounted to the H-shaped yoke between the second bifurcated leg pair adjacent a second leg upper terminal end, and the first exterior surface arcuate recess is positioned between the first leg interior arcuate recess and the first leg upper terminal end, and the second exterior surface arcuate recess is positioned between the second leg interior arcuate recess and the second leg upper terminal end.

8. Apparatus as set forth in claim 7 including a first pivot axle directed through the first leg adjacent the first leg upper terminal end to pivotally mount the first leg between the first bifurcated leg pair, and a second pivot axle directed through the second leg adjacent the second leg upper terminal end to pivotally mount the second leg between the second bifurcated leg pair.

9. Apparatus as set forth in claim 8 wherein the first bevel gear is defined by a first size and the second bevel gear is defined by a second size wherein the first size is greater than that of the second size.
