Abstract
702,366. Drilling. BOURBON TOOLS, Ltd. April 21, 1952, No. 10040/52. Class 83 (3). [Also in Group XXIII] Coarse feed is imparted to a slide 2, Fig. 3, of a drilling machine by a screw 6 journalled in a fixed upright 1 and engaging a nut 16 journalled in the slide, while fine feed is imparted by a spindle 23 which rotates the nut through worm or other gearing 21, 22, Fig. 2, the latter retaining the nut against rotation during coarse feed. A phosphor bronze ring 29 splined or keyed by pins 30 to the screw 6 may be clamped against a boss 7 by a flange 34 on a manuallyoperated, quick-acting nut 33 to hold the screw 6 against rotation during fine feed. Circlips 14, 18 and thrust races 11, 20 prevent axial movement of the nut 16 and screw 6. The latter is fitted with a graduated handwheel 9 co-operating with a pointer 28 while the spindle 23 is fitted with a knob 26 and a dial 27 co-retated to the thread of the nut 16 and the ratio of the worm gearing. Coarse and fine feed adjustments may be made simultaneously, and the mechanism'may be power-operated. The slide 2 may be the tool slide. Specifications 696,198 and 701,670, [Group XXIV], are referred to.
