Filed: 1924-09-12
Abstract: 244,174. Halliburton, E. P. Sept. 12, 1924. Bore-hole apparatus.-In drilling wells, the power from a single prime, mover is mechanically divided between means for rotating the drill stem and means for moving the stem rectilinearly, and the power applied to one of these means is regulated by the resistance to the power applied to the other means, so maintaining the requisite feed pressure and torque. In the welldrilling plant shown, the motor 15<1> through clutch 16 and bevel gears 50, 49, rotates a howsing 39 contained in a housing 19; the housing 39 carries the spider 40 of differential gearing 41. The stub shafts 47, 48 of the differential gearing may be connected by clutches 51, 52 respectively to shafts 17, 18, the shaft 17 acting through a worm 20 and rotary table 22 to drive the drill, and the shaft 18 being connected through a clutch, variable-speed gear 29 and worm gearing to a winch 32, and thereby, through cable 34, tending to lift the drill, which is slidably connected to the table 22. In normal operation, the weight of the drill overcomes the lifting tendency of the shaft 18, but when excessive resistance to rotation of the drill is encountered, the speed of the shaft 17 is reduced and the shaft 18 then rotates to reduce the load on the drill bit. Either clutch 51, 52 may be moved into engagement with a clutch face on the adjacent end of the housing 39 to lock the corresponding- stub shaft 47, 48 to the housing and to free the corresponding shaft 17, 18. Auxiliary lifting drums 60, 61 are provided, and are driven through bevel gearing 62, shaft 64, bevel gearing 67, and a clutch.
