Abstract

975,489. Drilling. INGERSOLL-RAND CO. June 4, 1963 [June 12, 1962], No. 22237/63 Heading B3C. An air operated drill comprises a body 1 formed by inner and outer cylinders 4 and 2. A piston 5 in the cylinder 4 has a rod 6 attached to an air motor 12 carrying a chuck 13. The reciprocation of the piston 5 effects the feed and return movements of the drill and is controlled by a spool valve 30. With the valve 30 in the position shown in Fig. 1 air is supplied to the chamber 8 to feed the drill forward. This movement is terminated by the contact of an adjusting screw 55 with a reversing valve 38 whereby air is exhausted from a chamber 34 to allow the valve 30 to move to the left, as in Fig. 2, due to a pressure differential. Air is thus exhausted from chamber 8 and admitted to chamber 9 to effect the return movement. The air supply to the rotary motor 12 is controlled by a motor valve 22 which is arranged to open just after the feed motion commences and remains open until the drill has completed the return stroke. This permits the drill to be rotated during both feed and return movements. The rates of these movements are controlled by needle valves 46 and 49. The cycle may be restarted at the end of the return stroke by depressing the recycling valve 41 or momentarily closing the main valve 16 in the feed line 15.
