Abstract
880,472. Jigs. MUNRO, G. R., and ZERE, E. P. Nov. 13, 1957 [Nov. 15, 1956], No. 34898/56. Class 83 (3). A jig for use in marking work 1 comprises a pivot 3 by which the jig may be secured through an intermediate member or, as depicted, direct to the work, an arm 6 rotatable about the pivot and graduated to position a slide 20 adapted to guide the marking tool (not shown), a dividing disc 9 secured on the pivot, and means 13 for locking the arm to the disc. The disc 9, a sleeve 8 on which the arm pivots, and preferably a spring washer 10a are clamped against a flange 4 on the pivot by a nut 10. A conical washer 14 centres the pivot in a hole 2 in the work and is clamped by a nut 16, preferably acting through a spring washer 17 and a sleeve 18. Axial index grooves 11 in the disc 9 are selectively engaged by a pin 13 lodged in a hole 12 in the arm, which has rack teeth 18a (Fig. 1, not shown), engaged by a worm carried by the slide and enabling adjustment of the slide by rotation of the worm. The end of a guide bush 28 for the marking tool engages a slot 7a in the arm.
