Abstract

158,682. Mitchell, F. B. Nov. 10, 1919. Pivoted-jaw wrenches.-An adjustable wrench comprises two members pivoted together at one end and formed with jaws at the other end, adjustable by a wedge, cam, or screw. As shown in Fig. 1, the jaw member A is folded or double, having the two parts connected at A<4> and the jaw member B works within it, pivoted at T. A spring B' on the part B engaging a cross-pin A<2> tends to open the jaws, and a wedge P movable between the part A<4> and the edge of the member B adjusts the jaws as required. The wedge is moved by a projecting finger-piece P<5>. In the modification shown in Fig. 9, a spring B<2> on the part B engaging a pin A<2> tends to open the jaws, which are moved by a wedge P having a projecting screw P<1> and lock-nut P<2>. A screwdriver B* may be formed on the part B. A double reversible wedge member P, R, Fig. 18, may be used for a greater range of adjustment. Two pivot holes T may be provided, the pivot screw being movable from one to the other for increasing the range of adjustment with the jaws approximately parallel. Fig. 20 shows a modification in which the jaw members A<6>, B<6> are moved against the pressure of the spring B<7> by a cam S pivoted in the member A<6> and bearing against the edge of the member B<6>. A set-screw bearing on the edge of the member B or B<6> may be used in place of the wedge P or cam S. For increasing the range of adjustment the set-screw or the cam S may be used together with a wedge P; or a double wedge may be provided.
