Filed: 1929-05-22
Abstract: 328,475. Pearn & Co., Ltd., F., and Pearn, H. A. May 22, 1929. Combined turning and boring machines; boring- bar machines.-In a horizontal boring and facing machine of the type in which the boring-bar c is traversed axially through a revolving head a across which the facing slide b is traversed, the hand adjustments of both the boring-bar and facing slide are effected by a single hand-wheel o acting in conjunction with a shaft 33 by which the power traverses of the bar and slide are effected. The facing-slide is operated by rack-and-pinion gearing e, worm gearing f, g, spur gears h - m, and differential gear n, the hand traverse being effected from the wheel o through spiral gears p, q, clutch r splined on the shaft 33, gears s, t and differential n. For power feed of the slide, the shaft 33 may be driven through worm gearing x, wand clutch v from a shaft y which is driven from the mandrel u through gears 20, 21, change speed gearing 6 - - 16, Fig. 2, and reversing bevel gearing 2 - - 4. The wheel 21 may be driven in the manner described in Specification 220,904. The boring-bar is traversed by rack-and-pinion gearing 22, 23 from a shaft 24 which is driven from the shaft 33 either at a high speed through gears 30-32 and bevel gears 25, 29 or at low speed through gears 32, 31 and worm gearing 26, 43. The high and low gears are selected by means of a clutch 27 operated from a rod 34 which may be shifted by a spindle 37, Fig. 3. A plunger 41 co-operates with a head on the rod 34 and with a recess in the clutch v so that when this clutch is engaged for the power feed, only the slow feed of the boring-bar can be engaged, but if the clutch v is disengaged and the shaft 33 rotated by hand, either the high or the low speeds for the boring bar feed may be employed.
