Abstract
380,469. Well-sinking, tunnelling, and excavating. HAMMER, L., 40, Bastiengasse, Vienna. March 24, 1931, No, 8998. Convention date, March 25, 1930. [Classes 68 (i) and 85.] Wells are bored by a system of chisels rotating in a plane containing the axis of the well, and also rotating at a lower speed about said axis, the system being progressively advanced along said axis and cutting the bottom of the well into hemispherical form. Percussive tools 2, Fig. 1, in one or more planes, are rotated about a shaft 1 in a fork 17 by a motor 4, the fork being rotated about the axis of the well through gearing 5, 5a, 6, 6a, 7<,> driven from the motor 4 or through gearing 11, 15 driven by a motor 10 or by reaction due to an inclined arrangement of the tools. The fork is supported in a frame 8 with an outer packing of bristles and spring-pressed guide rollers 25, the frame 8 being moved to feed the tools by pinions 35 engaging racks 34 on a frame 31 and driven through worm gearings 11, 14, 37, from the motor 10. Above the frame 31 is a frame 45, Fig. 1a, suspended by a cable 66 and balance weight, the cable 66 containing the cable 30 supplying current to the motors ; the frame 45 carries a tank 48 with a screen 58, a pump 51 drawing water from the tank for supply through pipes 53, 54, 56 to the tools, and an ejector fitting 55 inducing a current in one or more pipes 57 whereby debris is carried through pipe 57 and the hollow shaft 18 to the tank. The frames 8, 31, 45 carry hydraulic cylinders 27, 33, 46, or electromagnetic means, operating eccentrics 32, 47, to lock the frames ; rods 41, 62 act through pivoted members 42, 59 to control the cylinders 27, 33, 46, &c. automatically, whereby at the end of the feed of the frame 8, the latter is locked and the frames 31, 45 freed to allow them to descend successively, after which the frame 8 is freed and the frames 31, 45 are locked. One or more dashpots, each comprising a piston 64 and a double-walled cylinder 63b with an apertured valve 65, are provided between the frames 31, 45. To empty the tank 48, a tank 81, Fig. 5, with screen 74, is lowered down the rope 66 until a stop 93 contacts a lower stop on the rope 66, Fig. 1a, and operates pivoted levers 91 influenced by springs 90 and carrying rollers 92 which are then forced against the well sides ; in the descent a depending suction head 79 is steered by a cover 71 into the tank 48 and the latter is then emptied by a double pump 76 which also supplies water through a pipe 83 to loosen the debris. The tank 81 may be emptied above ground by opening a valve 86 by electric means 86a, and may deliver water directly to the tank 48 by opening valve 87 by electric means 87a. The percussive tools 2 may be replaced by freely rotating chisels carried by rotating discs &c. The Specification as open to inspection under Sect. 91 (3) (a) describes also well-lining means which now forms the subject-matter of Specification 380,451 and an excavating machine which now forms the subject-matter of Specification 379,297 and also referred to the modification of the boring and lining devices for tunnels. This subject-matter does not appear in the Specification as accepted.
