Abstract

354,723. Drilling. ADCOCK, G. and SHIPLEY, H., (trading as ADCOCK & SHIPLEY), Rex Machine Tool Works, Bright Street, Leicester. May 10, 1930, No. 14423. [Class 83 (iii).] Feed mechanism for drilling and similar machines of the kind wherein the feed is commenced by the coupling of a clutch, the working operation being performed within one complete rotation of a trip means which acts in conjunction with a weight, spring, or other means to return the tool to the normal position, is characterized by a device that automatically reclutches the clutch on the return of the tool to the normal position. The invention is particularly applicable to the apparatus described in Specification 287,304. As shown a main axle a<2> has a pinion a gearing with a rack on the feed sleeve of the spindle of a drilling machine. The pinion a is rotated upon engagement of clutch members d<3>, e<2> by a worm d and worm wheel d<2>. The clutch member e<2> is connected to a spring-actuated plunger e<4> within the axle a<2>. The axle a<2> may be rotated manually by a lever e slidable transversely of the axle a<2> within limits defined by stops h and having a groove e<5> which coacts with a ball or roller g in the end of the plunger e<4>. Displacement of the lever e to remove the ball g from the groove e<5> energizes the clutch parts d<3>, e2, and the pinion a is rotated. After the members a, e have moved a part of a revolution and the tool has performed its work an adjustable stop h<2> engages a conical face h<3> on the lever e and the latter is moved to register the ball g and groove e<5> and de-energize the clutch d<3>, e<2>. The tool is then returned to its initial position by the action of a spring f upon the axle a<2>. The end l<2> of the lever e thereupon engages a spring-pressed plunger i<2> and is moved to re-energize the clutch d<3>, e<2>, and the working tool again descends. A leaf spring m engageable with a conical face n on the lever e may be used instead of the plunger i<2>. Means may be utilized for holding the plunger i<2> out of action so that the apparatus may be used as described in Specification 287,304, [Class 83 (iii), Metals, Cutting].
