959,884. Cartridge-actuated tools. AMP Inc. Jan. 30, 1963 [Feb. 9, 1962], No. 3754/63. Heading B4C. [Also in Division H2] An explosively-driven tool, Fig. 4, for wedging two cables 33 into a connector 5, comprises a connector-holding tool head 9 pivoted at 10 to receive connector 5 and then locked by a latch 16, and a tool body 11 including a ram housing 19 in which a ram 20 moves under the action of an explosive charge contained in a cartridge case 34 to drive a wedge 6 between the cables 33. Ram 20 has a plunger portion 25 with a firing pin 30 at its free end which extends into a breech member 26 mounted by a peripheral flange 27 between ram housing 19 and a screw-on collar 29. The breech member 26 contains cartridge case 34 holding explosive 38 beneath a plug 39 in which is disposed a percussion cap 40, and is closed at the bottom end by a screw cap 31 having a spike 32 which pierces the closed end of cartridge case 34. When cap 31 is struck, firing-pin 30 detonates percussion cap 40 and plug 39 is driven along the case 34 forcing ram 30 upwardly. At the end of the stroke, plug 39 is fused to case 34 so that the gases cannot escape into breech member 26, and these gases are finally released by unscrewing cap 31 and withdrawing spike 32. Another tool, Fig. 9, for use with a modified connector (see Division H2) having two wedges which are driven inwardly of the connector in opposite directions, has a similar tool body to that above, and a modified tool head 48 with two toggle driving arms 62 pivotally connected to links 57 which are themselves pivotally connected to a member 55 sliding in a slot 58 under the action of a ram 50. Specifications 873,192 and 956,227 are referred to. |
