Abstract
A cartridge magazine for explosive powder charge-operated setting tools including a charge-receiving member (2, 12, 22) having a plurality of spaced from each other, charge-receiving chambers (3, 13, 23) for receiving propellant charges (6, 16, 26), respectively, and a bottom (1, 11, 21) for closing the charge-receiving chambers (3, 13, 23) and formed of a heat-releasing, fusible and current-conducting foil.
Claims10
An explosive powder charge-operated setting tool for use with a cartridge magazine having a charge-receiving member (2) having a plurality of spaced from each other, charge-receiving chambers (3, 13, 23) for receiving propellant charges (6, 16, 26), respectively, and a bottom (1, 11, 21) for closing the charge-receiving chambers (3, 13, 23) and formed of a heat-releasing, fusible and current-conducting foil, the setting tool comprising an electrical current source (10) having electrical positive and negative contacts;
- an electrode (9, 19, 29) connected with one of the positive and negative contacts;
- an insulator (7, 17, 27) for receiving and guiding the electrode (9, 19, 29) and which can be connected with the bottom (1) of the cartridge magazine;
- and conductor means for connecting another of the positive and negative contacts with the bottom (1), wherein the insulator (7, 17, 27) has an expansion chamber (8, 18, 28) open at a free end of the insulator (7, 17, 27), the electrode (9, 19, 29) projecting into the expansion chamber (8, 18, 28).
A cartridge magazine for explosive powder charge-operated setting tools, comprising a charge-receiving member (2, 12, 22) having a plurality of spaced from each other, charge-receiving chambers (3, 13, 23) for receiving propellant charges (6, 16, 26), respectively;
- and a bottom (1, 11, 21) for closing the charge-receiving chambers (3, 13, 23) and formed of a heat-releasing, fusible and current-conducting foil for forming, upon firing of a setting tool, hot droplets for igniting the propellant charges.
An explosive power charge-operated setting tool for use with a cartridge magazine having a charge-receiving member (2) having a plurality of spaced from each other, charge-receiving chambers (3, 13, 23) for receiving propellant charges (6, 16, 26), respectively, and a bottom (1, 11, 21) for closing the charge-receiving chambers (3, 13, 23) and formed of a heat-releasing, fusible and current-conducting foil for forming, upon firing of a setting tool, not droplets for igniting the propellant charges, the setting tool comprising an electrical current source (10) having electrical positive and negative contacts;
- an electrode (9, 19, 29) connected with one of the positive and negative contacts;
- an insulator (7, 17, 27) for receiving and guiding the electrode (9, 19, 29) and which can be connected with the bottom (1) of the cartridge magazine;
- and conductor means for connecting another of the positive and negative contacts with the bottom (1) for fusing the bottom upon firing of the setting tool.
