Abstract
817,863. Drilling-machine details. PADLEY & VENABLES Ltd. Jan. 5, 1956 [Jan. 5, 1955], No. 362/55. Class 83 (3). A wet-drilling attachment for a rock drill comprises a non-metallic hollow body 10 in which a member 11 for coupling the drill rod 12 to the drive-shaft 13 is mounted in non-metallic bearings 14, 15, spaced apart to provide an annular chamber 16 for water fed to the hollow drill rod from a connection 21, through ports 20 in the coupling-member 11, and seals 18 at the ends of the chamber 16 and positioned by a sleeve 17 permitting at 19 the passage of water, the body 10 and bearings 14, 15 being retained on the coupling-member 11 by abutments 25, 29 on the coupling member and shaft 13. The member 11 has driving-dogs 26 at one end for engaging the helical ribs 27 on the drill rod, and is preferably screw-threaded at the other end for engaging the shaft 13, the loose washer 29 being clamped between the member 11 and helical ribs 30 on the shaft 13. The bearings 14, 15, sleeve 17 and body 10 may be made of the material known under the Registered Trade Mark " Tufnol," and a stainless steel sleeve 24 may line the inlet 21 for a water valve 22, preferably of the diaphragm type.
