Abstract
565,716. Drilling. STAINTON, D. E. May 27, 1943, No. 8482. [Class 83 (iii)] A jig for use in drilling holes located by a series of triangles, comprises three hinge members, the pivots being removable flanged slip bushes, the flanges 42 having grooves to pass swarf and being notched to engage a pin 23 on one member of the hinge. The end faces 25 of the hinge members are ground to known distance from the axis of the hinge and the sides of the triangle are completed by length bars and slip gauges 26 wrung together. The parts are clamped by a steel tape 30 passed round the jig being clamped at 11 and tensioned at 16. The bushes may have oil grooves in their bores. The bushes are clamped through spheres 41 bored to a clearance size for the drills, seated in countersinks in the flanges and in plates 40 having a ball fulcrum at 44 and clamping screw 43. In a modification, all the hinge members are alike and the ends of the tape are secured by a screw 32 and plates 46 within a forked member 31 guided in a slot in a housing 34 for tensioning at 37.
