Description: |
| Claim:
In a dividing head adapted to be attached to a lathe, a worm gear adapted to be secured to the spindle of the lathe, a pivot shaft adapted to be supported on one side of the headstock of the lathe, a body member pivoted on said last shaft and adapted to be swung from a vertical to a horizontal position thereon, a worm shaft journaled in said member, a worm secured to said shaft, a hand wheel having a flat graduated circumferential face carried by said worm shaft and adapted to rotate the lathe spindle in either direction through the medium of the worm and the worm gear when said body member is swung to a horizontal position, a vernier ring resiliently supported on said member and having graduations on its face in cooperative relation with said first graduations, and means partly on said member and partly on said headstock for retaining said worm and said worm gear in operative relation while a dividing operation is being accomplished and for deeply meshing the teeth of said worm and worm gear after a desired setting of the hand wheel is obtained thereby locking the spindle against further movement, said means including a spring plunger which may be disengaged when the lathe is to be used without said attachment whereby said body may be swung upwardly more than ninety degrees. |
