Abstract

842,251. Drill jigs. RYTOL Ltd. Dec. 18, 1958 [Dec. 18, 1957], No. 39299/57. Class 83 (3). A drill-jig comprises a jig-plate 7 with rows of holes 11 and slidable in a frame 1, a micrometer-head 12 for adjusting the plate in a direction 8 parallel to the rows of holes, and means 16 for clamping the plate after adjustment. Strips 9 guide plate 7 as it is moved by head 12 relatively to its supporting slide 4, which is movable, transversely to the movement of plate 7 in the slide, in guides 6 in frame 1 by a further micrometer-head 13. Springs press the plate and slide against the micrometer-heads 12, 13, respectively, and the slide slides on ball-bearings 10, Fig. 4. Slide 4 is fixed by two of the clamps 16. Work to be drilled is clamped between the frame 1 and a worktable (not shown), by bolts in slots 2 in the frame.
