Saw vise with independently pivoting jaws that uses spurs on the rear jaw to attach to a bench making it "practically self-fastening. One of the notable features of this clamp is a unique "sound deadener" which utilized a spring and rubber block (eliminated in the later patent). This is Binkerd's earlier patent which he later improved with in patent 571,742.
