Title: Improvements in rock drilling device
IPC: E21B19/084
Filed: 1952-03-06
Abstract: 695,006. Rock-drilling machines. BOSCH GES., R. March 6, 1952 [March 24, 1951], No. 5818/52. Class 83 (iii). A rock-drilling machine 4, Fig. 1, is fed along a hollow support 1 by a pressure-fluid piston 9 and a cylinder 6 housed within the support 1, and an intermediate connection 13 through which the piston and cylinder feed the machine 4. The machine 4, which is electrically operated, is mounted on a slide 3 fixed to a chain 13, steel cable, or other flexible intermediate member. The latter is passed around an axiallystationary pulley 12 and a pulley 11 on the piston-rod 10, and is anchored at 14 to the inside of the support 1. When pressure-fluid is delivered to the cylinder 6 through a pipe 24, the pulley 11 is moved away from the cylinder, drawing more of the chain 13 into the support 1 and consequently feeding the drill 5. The extent of feed movement may be adjusted by varying the part of the chain 13 attached to the slide 3. An electric motor 17 drives a pump 16 for supplying pressure-fluid through a pipe 21 to a valve 22 controlling the feed piston, the fluid being drawn by the pump from interconnected reservoirs 18, 19 positioned one on each side of the housing 1 and each connected to the valve 22. In the setting illustrated of a control 23 for the valve 22, pressure-fluid is being delivered along the pipe 24 to feed the drill. The control 23 can be turned through 90 degrees to connect the supply of fluid to the reservoir 19, Fig. 2 (not shown), and allow the drilling-machine to be returned by manual means, fluid returning along the pipe 24 being directed by the valve to the reservoir 18. The pressure of the fluid from the pump can be adjusted by a governor controlled by a handle 27. In a modification, Fig. 3, a gland is formed on the open end of the cylinder 6 to make the piston double-acting in order to effect power-operated withdrawal of the drill. Withdrawal of the piston is transmitted to the slide 3 by a chain 33 secured at its ends to the inside of the housing 1 and the slide 3 respectively, and passed around a further pulley 32 supported on the end of the piston-rod 10 and an axiallystationary pulley 35. The valve 22 is modified to facilitate supplying fluid to both sides of the piston 28 alternately. Since the cross-sectional area of the cylinder is reduced by the piston-rod 10 for the return stroke, this stroke will be effected at a higher speed than the feed stroke. One or two chains 13, or 33, with a correspond. ing number of pulleys, may be provided, instead of one of each, to produce symmetry about the piston-rod 10. The pump 16, motor 17 and, if desired, also the reservoirs 18, 19 may be united to form a single unit to be secured to the support 1. Supports and guides (not shown) may be provided for the chains, piston-rod and drill.

Abstract: 826,380. Step-by-step conveyers; roller conveyers. YORK ENGINEERING & CONSTRUCTION CO. Feb. 28, 1956 [March 3, 1955], No. 6147/56. Class 78 (1). [Also in Group XII] In a conveyer system for moving lengthy steel tubes, bars, &c. through a continuous heattreatment furnace, the tubes 18 are fed through an opening 19a on to conventional skewed rollers 20 each having an independent drive 21, are rolled through the furnace by a step-by-step conveyer having fixed and movable bars 24 and 25 respectively formed with toothed upper edges, and are discharged through an opening 28 by skewed rollers 26 each having an independent drive 27. The rollers 20 and 26 impart a rotary as well as an axial movement to the tubes 18. As each tube traverses the rollers 20 it strikes a stop 22 energizing a motor 68, Fig. 7, which, through a crank 69 and lever motion, rocks lifter bars 23 attached to a shaft 66, lifting the tube off the rollers. The tube rolls down the lifter bars against stops 23d, and further rotation of the crank 69 lowers the bars 23, depositing the tube on the fixed conveyer bars 24. The bars 25, having teeth 25a, Fig. 10, positioned approximately mid-way between corresponding teeth 24a on the fixed bars, are given a circular motion which lifts and drops the tube with a rolling motion over the next teeth 24a on the fixed bars, resulting in the tube being eventually rolled across the furnace on to the discharging rollers 26. The bars 25 may be given a vertical or an inclined linear movement, Figs. 15-19 (not shown), or, with a circular motion, the teeth 24a, 25a may be so shaped as to give a rotative transfer movement to square or rectangular billets, Figs. 20-25 (not shown). The bars 25 are supported on pedestals 42, Fig. 4, extending through holes 43 in the furnace hearth 31 and resting on longitudinal girders 41 supported in turn by a pair of transverse girders 38, 39. Each of the latter has a pair of rotary supports, each comprising an eccentric 50 driven by a shaft 47 connected through gearing to a single motor, Fig. 9 (not shown), and a connecting-rod or pitman 40B pivotally connected to the girder by a pin 54 engaging the legs 55, 56 of a yoke 57. To prevent leakage of cold air into the furnace through openings 43, plates 58 sliding in guides 62 are fitted around the pedestals 42. Specifications 826,381 and 826,382 are referred to.
