Abstract

198,716. Asquith (1920), Ltd., W., and Feather, G. Dec. 13, 1921. Drilling-machines, particularly radial drills, are arranged so that the engagement of the power feed automatically locks the drill-positioning adjustments. When the lever a<2>, Fig, 1, is rocked to expand a friction ring F in the boss of the worm-wheel bv means of the wedges a<4>, a<5> an adjustable link a<1> rocks a shaft B that locks the arm to the column as described in Specification 137,118 and by means of screw gears a, C rotates a screw c<1> to force a wedge c<2> between a, part of the saddle and. the radial arm. In a modification, the pilot wheel for the hand-feed is mounted on a sleeve concentric with the shaft that carries the pinion for traversing the saddle on the arm. Power feed is obtained from a worm-wheel splined on the sleeve to move into engagement with the driving arm. The sliding is effected by a lever linked to the shaft Band to a screw that actuates a lamp engaging one of the slideways on the radial arm. In a further modification, the concentric arrangement of feed and traversing shafts is retained, and the pilot wheel for the hand feed acts through a spring- pressed ball f<9>, Fig. 4, that yields when the drill meets the work. A quick pitch screw f<6> then slides a yoke a<6> to operate the wedge a<4> of the friction clutch, at the same time rocking the shaft B and locking the saddle &c. as in the first modification.
