Abstract

283,147. Guerre, P., and Berry, F. J. B. Jan. 5, 1927, [Convention date]. Drills.-A drilling machine is held between yokes 18, 17 held together by bolts 19 and embracing spaced jacks 8, 9 to which they are normally fixed by screws 20. The jacks are connected by a cross-piece 15 and a conduit 11 and are operated by compressed air supplied through a pipe 10. After loosening the screws 20, the machine may be moved on the jacks by rack and pinion, block and tackle or other means, preferably by a cable 21 passing over a pulley 23 and a drum 24 secured to a rotatable part of the machine, the cable being engaged with the drum when desired by pulling on its free end 25
