Abstract

331,739. Cincinnati Bickford Tool Co., and Klausmeyer, D. C. Aug. 23, 1929. Drilling.machines; tapping.- The spindle of a combined drilling and tapping machine is adapted to be fed during drilling by gearing driven from the spindle, or by a readily removable feed screw and nut during tapping, the screw and :nut being situated approximately at the middle of the spindle and being divided to permit ready removal in a lateral direction. The machine comprises a pillar 1 carrying a gear-box 2 for the spindle, driving-gear which is connected to a motor M, and a feeding head 4 which is vertically adjustable on the pillar by means of screws 10 and sets of tapped holes a - - c in the pillar- For drilling, the spindle Sis fed by a rack 6 and pinion 7 which may be rotated by a hand wheel 9 or by bearing x, shaft 23 and either of the gear trains 21, 22 or 24, 25. Fig. 2, from a pinion 20 on the spindle. S. The double gear 22, 24 is moved axially to feed the drill at one of two speeds by a hand lever 27, Fig 1, or the gear may be made to occupy an intermediate disengaged position during tapping. For a tapping feed a two-part nut 29, hinged at 30 and clamped together by bolts 31, is secured to the feeding head 4 by screws 28 and engages a screwed sleeve 34, Figs. 2 and 3, having an open side 40 to allow it to be placed laterally on the spindle S. The axial position of the sleeve 34 is determined by collars 36, 37 secured to the spindle by pins 38 engaging any two of a series of slots t in the spindle and the sleeve is rotated by a key 35 on the, spindle. The spindle is rotated from the motor M by gearing 12, 14 and oppositely rotating bevel gears 15, 16, either of which may drive the spindle through clutches 17, 18 controlled by a hand lever 19. The removable lead screw and nut 29, 34 may be used on a machine for tapping only.
