Description: |
| Abstract:
My invention relates t o that class of saw-mill dogs in which the dog or tooth is arranged in a sliding head, which is adjusted by means of a pinion or toothed segment over a vertical rack-bar affixed to the side of the knee of the log-carriage. My invention consists in combining with said sliding head, pinion, and rack-bar a lever having a loose play about the axis of the pinion, with peculiar bearings for the same, and a tooth adapted to enter and remain in the notches of the pinion, to turn it when the lever has one of its bearing-surfaces on the axis of the pinion, and which lever and tooth are adapted to move out of range of the pinion to turn back over the same when the lever is adjusted away from the axis of the pinion. It also consists in peculiar means for locking the dog to the sliding head.
Claim:
The combination, with the head-block, the loose pinion, the axial bolt securing the latter to the head-block, and the rack-bar, of the handle-lever having branched ends c e with elongated openings in them, with independent bearings, e, e', and a tooth, d. |
