Description: |
| Abstract:
This invention relates to that type of sawmill head-blocks wherein an under dog is provided as well as an upper dog, so that the log or board may be held at the bottom as well as at the top. The object of my improvement is to so arrange the under dog that it wilt be entirely out of the way and to provide a strong and compact mechanism for operating it. My improvement consists in arranging this under dog in a chamber or recess formed in the head-block, and combining it with an eccentric and eccentric-rod for raising and lowering it.
Claim:
The combination, substantially as before set forth, of the saw-mill head-block constructed with a chamber, the under dog pivoted to the head-block within said chamber, the eccentric in said chamber above the dog and journaled in the side of the head-block, and the eccentric rod and strap for connecting the pivoted dog with the eccentric. |
