Title: Cartridge-operated tool for driving bolts into masonry, structural parts and the like
IPC: B25C1/14
Filed: 1962-04-13
Abstract: 1,006,410. Cartridge-operated fastener-driving tools. E. BELSTEIN, and E. BAUER, [trading as CARL BAUER]. April 13, 1962 [April 13, 1961; June 22, 1961], No. 14459/62. Heading B4C. [Also in Division F3] A cartridge-operated tool for driving a bolt 18 into masonry or the like comprises a piston 16 slidable within a housing 5, 6, 8 and a cartridge holder 33 within the housing and which is only within the range of action of a firing mechanism 35, 36 when the tool is loaded with a bolt, the cartridge holder always assuming the same position in relation to the firing mechanism independently of the length of the bolt to be driven in. The piston 15 is slidable in a sleeve 31, one end of which slides in a tube 5 and the other end 33, which constitutes the cartridge holder, slides in a portion 8 of the housing. A cap 4 is secured to the tube 5 which slides in an outer sleeve 6 screwed into the portion 8, the tube being normally urged to the position shown in Fig. 4 by a spring 12. The spring mechanism is hinged to the portion 8 and is locked in position by a catch 39. A spring-loaded firing pin 35 slidable within a bush 36, is released after loading, by a trigger 38. In operation, after a bolt 18 has been inserted into the end of the piston 15, the cap is pressed against the masonry 16, the tube moving against the action of the spring 12 until the point of the nail engages the masonry and the end 27 of the piston is pressed into a bore 34 of the cartridge holder in which a cartridge has been previously fitted. Continued pressure causes a shoulder 32 on the sleeve 31 to be moved by the piston into engagement with an abutment 9 and, at the same time, cause the end face of the cartridge holder 33 to abut the spring-loaded bush 36 and cock the firing mechanism. After release of the trigger 38, the cartridge is fired and the expanding gases act on the end of the piston 20 so as to drive the bolt into the masonry, the excess gas pressure acting against the end face of the bush 36 to thereby lift it away from the bore 34 and so vent the gas therein and also loosen the cartridge. In order to prevent the bolt from dropping out before firing it is fitted with a collar 44 which is clipped behind two spring- loaded detents 43. The end 27 of the piston may be made as a separate part in order to facilitate replacement.

Abstract: 928,031. Locating conductive bodies; detecting voltage presence. CENTRAL ELECTRICITY GENERATING BOARD, G. L. DOUGLAS, E. F. HASLER, and P. S. VICK. July 27, 1961 [April 27, 1960], No. 14809/60. Class 37. [Also in Group XXXV] An apparatus for the detection of the presence of an earthed body 10, Fig. 1, comprises a pair of conductive members 13, to the lower of which an alternating voltage with respect to earth is applied, and detector means 15 responsive to the resultant alternating voltage between the two members due to their impedances to each other and to earth. The apparatus is applied to give a warning if the jib of a crane approaches an earthed conductor. 12-Volt D.C. power applied at terminals 30, 31, Fig. 2, to energize the detector unit 23 is converted to A.C. by a pair of switching transistors 35, 36, in a selfoscillating circuit arrangement, through transformer windings 37, 38, the input voltage being stabilized by a series transistor 42 the base of which is controlled by the potential at the junction of a resistor 41 in series with two Zener diodes connected across the input terminals. A winding 54 on transformer 32 applies a low voltage A.C. with respect to earth, to the chassis and outer probe electrode 25. Relay 63 controlling contacts 70 is normally energized, and is released by A.C. from a live main in the vicinity appearing on electrode 24, the voltage developing a bias in the output circuit of a rectifier 66 which causes the mean current drawn by valve 53 to fall sharply when a predetermined voltage is present. The apparatus responds similarly to the approach of an earthed body because of the chassis voltage applied by winding 54. The voltage which should be low enough to prevent shock may have a frequency higher than the mains. A switch 75 is provided to connect an earth for apparatus test purposes and interchangeable probes of different sizes enable the sensitivity to be modified.
