Abstract

513,819. Torque measuring wrenches. AUTOMOTIVE MAINTENANCE MACHINERY CO. Oct. 3, 1938, No. 28703. Convention date, Dec. 20, 1937. [Class 106 (ii)] [Also in Group XXIII] A work-engaging member 11 and a grip member 15 are fixedly secured to opposite ends of a spring bar 10, the deflection of which is measured by means allowing unobstructed free flexing of the bar. The member 11 has an opening 13 extending at right angles to its axis in which the forward end of the bar 10 is freely received and clamped by set screws 14. An adapter element 12 is fitted to engage a socket. A flat strip 16 overlying the member 10 has its forward end mounted on an upstanding stud 17 on the member 11 and is held in place by a nut 19 and washer. The other end is offset and lies close to the grip. The extreme end is widened and extended on both sides to provide a scale reading from a central zero which registers with an index mark on the grip. Accidental displacement of the end 16a is prevented by a U-shaped guard 24 the legs of which are secured to the ends of the part 20 by screws 25. In a modification, the scale is formed on a grip shaped like a knob and a long pointer attached to the head moves over this scale. In a further modification, the end of the strip 16 carries a dial indicator, the pointer spindle of which has a pinion engaging a rack extending at right angles to the bar which is of rectangular section, the rack being adapted to slide along the bar and being kept up to the pinion by a small spring. In this form the head is provided with ratchet teeth on the lower face adapted to engage similar teeth on a part connected to the adapter, which can slide axially of the head a limited amount for the teeth to clear one another. When the device is moved clockwise the work is under torque, when moved counter clockwise the ratchet teethcarry the head away from the adapter. In a further modification, the scale member 20 registers with a mark on a plate which has a small adjustment transversely of the device by screw and slots.
