Abstract
377,344. Well-drilling plant. NATIONAL SUPPLY CORPORATION, 120, Broadway, New York, U.S.A. May 14, 1931, No. 14268. Convention date, May 28, 1930. [Class 85.] A rotary well-drilling machine with hydraulic feeding-means comprises a base 1 supported on beams 2 and fixed to the upper covers 20 of three hydraulic cylinders 27 by bridges 21 ; the lower ends of the cylinders are connected by a ring 30 with an annular passage 31 for supply of pressure fluid, while such fluid may be supplied to the upper ends of the cylinders through a common passage 25 in the base. Pistons 28a in the cylinders are connected by rods 13 to a spider 12 in which a rotary table 7 is supported on upper and lower ball bearings 11, 17 which transmit upward and downward thrusts ; the supporting ring 16 of the ball bearing 17 is threaded to the table and locked by a dowel 19. A sleeve 8 depends from the table 7 and is slidably splined to a pinion 4 rotatable between ball bearings 5, 6 in the base band driven through gearing 37, 39, 41 in an extension 36 of the base. The table 7 receives a bushing 33 with slips 34 which grip the drill rod.
