Abstract
24,861. Webster, W.A. Nov. 25. Sawing.-Relates to a guard for circular saws which is raised automatically by the wood as it advances. The hood a, which covers the saw, is connected to the supporting-barf by two parallel links h. The bar f is held adjustably in a bracket e clamped on the end of an arm d which is mounted on the top of a pillar c. A counterbalance weight i facilitates the lifting of the hood. A friction-wheel l is mounted on the front of the hood. The bracket e may be bolted to a beam supported from the roof.
