Abstract

788,115. Torque spanners. ACRATORK ENGINEERING CO., Ltd. March 27, 1956. [April 7, 1955], No. 10348/55. Class 61. [Also in Group XXIV] A torque limiting spanner intended for duty in a range from 50 to 250 pounds/feet has a driving component 5, 7 which is connected to a driven component 8, 13 through a slipping clutch. A coupling member 6 of the clutch transmits rotation through the two taper rollers 9 which mate with recesses in the other coupling member 8. The rollers shown are pressed into the recesses by a spring 18, the compression of which can be adjusted by means of a bush 22 so. that the rollers will lift out of engagement when the required maximum torque is exceeded. The coupling members are located one on the other by a dependent rim 11 and the whole mechanism is enclosed in a casing 17 supported by four pillars 14.
