Abstract
1,185,050. Clinometers. BYRON JACKSON Inc. Aug. 16, 1967 [Sept.23, 1966], No.37787/67. Heading G1F. [Also in Division E1] Apparatus carried by a dull string for signalling its angular position relative to the vertical comprises piston 25 carrying sleeve 23 slidable in tube 21 and urged to the position shown by dulling fluid (air or gas) flowing down the string. When the flow is stopped, spring 31 raises the piston releasing pendulum 34 which engages one of the shoulders 35, depending on the indication of the string, to limit upward movement of the piston. When flow is recommenced, the piston moves down and ports 24 in sleeve 23 pass over parts 20 in tube 21 causing pulses in the fluid. The pulses are counted to indicate the angle. The interior of pendulum housing 5 is filled with oil forming a dashpot to retard downward movement of piston 25.
