Abstract

600,204. Pliers and wrenches. SEYMOUR SMITH & SON, Inc. April 16, 1945, No. 9446. Convention date, Aug. 23, 1944. [Classes 61 (ii) and 61 (iii)] The stationary handle 10 of a pair of pliers or a hand-grip wrench has a work-engaging jaw 11 rigidly secured to it, adapted to co-operate with a swivelled jaw 12 pivoted to an intermediate lever 15 secured to the stationary handle 10 by means of a pin 16. A movable handle 19 pivoted to the intermediate lever 15 by the pin 20 and a coiled spring 21 attached to the lever 15 and the stationary handle 10 are the operating means of the pliers. In order to produce a strong gripping action of the swivel jaw 12 against the jaw 11, provision is made of a toggle link 26 connected by a pivot pin 27 to the movable handle 19. The toggle link 26 is provided with a rear concave socket 28 for engagement with a convex pin 31 formed on the front end of a screw bolt 30. The swivelled jaw 12 and the intermediate lever 15 are provided with trunnions 17 to take the stress from the pivot pin 14. Specification 561,138 is referred to.
