Abstract:
This improvement is designed to obviate the defects experienced in Mr. Beard's spring, and consists in having the frame containing the spring made in two parts instead of one, the second part being made 1G movable by screws designed to tighten the web, and regulate the spring when settled down or sagged by long use, without being obliged to tear the saddle to pieces or substitute a new spring.
Claim:
The addition of the two screws for raising the webbing when required. |
