Abstract
759,104. Wrenches. MILLER P. C. July 22, 1954 [Aug. 3, 1953], No. 21392/54. Class 61 The supporting elements 2, 6, of the moving and fixed jaws 3, 7, of a wrench are telescopically interconnected by screw and nut adjusting means 4, 13, the adjustment being effected by outer and inner sleeves 8, 11, of which sleeve 8 forms the handle and sleeve 11 forms the nut. These two sleeves, which are interconnected as at 18, 19, form an annular compartment 14 which receives a sleeve like part of the element 6, and within the inner sleeve slides a screwed shank part of the element 2. Thus, by rotation of the sleeve 8 the sleeve 11 turns with it and by its nut part 13 causes the required movement of the moving jaw. A spring 16 bearing against a flange 12 of sleeve 13 and against a removable ring-like abutment 17 on the element 6 tends to urge the jaws apart. In a modification, (Fig. 4, not shown), the fixed jaw is pivoted to lugs on the element 6. Another pivoted jaw arrangement is shown in Fig. 5. which shows two serrated jaws 3b, 7b, carried by supporting elements which have adjustment means as shown in Figs. 1 and 3. The "fixed" jaw is pivoted at 27 to lugs 26 on element 6 and has a pin and slot connection 34, 36, with a spring- urged control lever 31 also pivoted to the element 6. The arrangement is such that the spring returns the "fixed" jaw to the open position when released.
