Abstract

668,346. Work-holders. PAINTER BROS., Ltd., and NOCK, J. L. May 25, 1950 [Oct. 7, 1949], No. 25794/49. Classes 83 (iii) and 83 (iv). Drilling-jigs.-Apparatus for locating a blank 23, Fig. 2, in different positions for punching, drilling, &c. holes comprises a movable frame 15 adapted to hold the blank and located by two pins 18 which engage holes 20 in two identical templates 5, Fig. 1. A table 1 for mounting on a punch or drill table at bolt holes 2 has an aperture 3 for the punch or drill and a slide 4 with an undercut edge 7 registering with one edge of each of the templates 5. The templates are adjustably located by clamps 9 having bolts 11 projecting through grooves 8 in the table 1. The frame 15 adjustably supporting the blank 23 runs on ball feet 19 over the table 1 and comprises front and side members 16 and a back member 17 welded together. The frame carries two members 24, 25 adjustably fixed in position by bolts extending through slots 28, 30 in the front and back members. The blank 23 rests on the members 24, 25 and is clamped in position by a sawtooth edge 34 on the member 25 which is engaged against the blank by a hand grip 36. Adjustable clamps 21, 31 on the members 17, 24 serve to locate the blank. A projection 41 on the member 25 is arranged to support gusset plates with obtuse-angled corners.
