Abstract
800,676. Securing cartridges in boreholes. ROLFES, Ltd. March 27, 1957 [April 4, 1956], No. 10226/56. Class 9(1) Resilient means for securing a cartridge in a borehole comprises an element which may be attached to the rear end of the cartridge and arms or prongs extending radially from the element with an overall diameter greater than that of the borehole. In Fig. 2, resilient wires 2 extend diametrically through a cardboard tube 1 and may be soldered together at the centre. The tube is placed over a cartridge with the wires contacting the base. A modification is made from sheet metal e.g. brass, cut to form radial arms 3, Fig. 4, between which portions 4 are upset at right angles to the sheet to form supports for the cartridge. Openings 5 may be provided for the leads of a detonator. In Fig. 5 radially arranged wires 6 are bent to form arms 7 which are soldered together and to clamps 9, 10. When the arms 7 are pressed into the base of a cartridge, the clamps 9, 10 grip the lateral surface. The clamps may be omitted and the radial arms bent slightly away from the central hub.
