Description: |
| Abstract:
My invention relates to metal-saws, and more especially to hot-saws for severing tubes to as they come from the sizing-rolls. The object of my invention is to provide a metal-saw in which the slipping of the driving-belt or other driving means is entirely or largely prevented and which is adapted to sever tubes or other articles of various sizes.
Claim:
In a metal-saw, the combination with a support for the article, a swinging frame, a rotary saw mounted therein in position to swing across the support, a driving-pulley for the saw-arbor, a belt, and a power-driven pulley mounted on a center separate from that about which the saw-frame swings and so located that the distance between its center and the center of the saw-pulley increases as the saw swings to its final active position. |
