Abstract
287,304. Adcock, G., and Shipley, H., (trading as Adcock & Shipley). Feb. 25, 1927. Drilling.-In a drilling or like machine wherein the change from hand to power feed and vice versa is controlled by manipulating the hand lever which effects the feed, the pinion d which engages the rack on the spindle sleeve is rotated, by a shaft e through which passes the hand feed lever e<2>. A sleeve i, slidably keyed to the shaft by a transverse pin j<2>, has clutch teeth adapted to engage similar teeth on a member k rigidly secured to a worm-wheel h which is continuously rotated from a power shaft g<2>. The clutch parts are normally separated by a spring m but may be engaged by sliding the lever e<2> transversely of the shaft so as to cause a ball or roller l to ride out of an annular groove l<2> in the lever. To stop the power feed at any predetermined point a cam o fixed to a stationary disc o<2> adjustably secured to the casing f of the gearing is adapted to engage a bevelled collar n on the lever as the latter rotates and cause the ball to enter the groove l<2> and release the clutch. Should it be desired to render the power feed inoperative, a nut n<2> may be secured along a sleeve n<3> secured to the lever so as to engage the collar n with a sleeve e<4> on the shaft and maintain the lever in its central position. The drill spindle may be returned by a spring e<3> with or without weights, and the individual teeth of the clutch k, i, preferably include an angle of 90‹.
