Abstract
1348379 Portable drill VICTOR PRODUCTS (WALLSEND) Ltd 22 Oct 1971 [22 Oct 1970] 50239/70 Heading B3C A hand held drill comprises a casing 1 on which the drilling pressure is applied, and a motor 4, the supply of power to the motor being controlled by the yielding of motor 4 relative to casing 1. Motor 4 may be pneumatic or hydraulic. When an hydraulic motor is used a valve block 7 is attached thereto and the motor and block are supported in the casing by a trunnion 5, and a recess 6, against the action of springs 8, 9. A spool valve spindle 11 is urged against a stop 12 by a spring 13 and is connected to triggers 16 by levers 18, 17. When pressure is applied to a bit held in a chuck 10 motor 4 and block 7 are pushed back relative to casing 1 but spindle 11 is prevented from moving by stop 12. The spindle therefore moves forward relative to valve block 7 and opens the valve so that fluid flows to motor 4 and rotates the drill. The drill can be rotated before being brought up to the work by depressing trigger 16.
