Abstract

280,080. Greve, E. E., and Oil Well Supply Co. Feb. 21, 1927. Borehole apparatus.-In a machine comprising a rotary table 5 with a bore receiving a series of bushings 17, 18, 19, locking means are provided which secure the bushings and table against relative vertical movement and are actuated by positioning the bushings. As shown, each bushing carries locking means comprising a slidable member 30 pressed by springs 32 bearing against fixed pins 35, and each member 30 has an opening adapted to receive a locking pin 36. The locking means connecting the bushing 17 and table 5 is operated by inserting the bushing 18, and that connecting bushings 17 and 18 is operated by inserting the bushing 19. An opening h is provided through which a pin may be inserted to free the locking means connecting the bushings 18, 19.
