Abstract
905,507. Fluid-pressure blasting cartridges. OLIN MATHIESON CHEMICAL CORPORATION. June 9, 1960, No. 20331/60. Class 9 (1). In a modification of the fluidpressure blasting cartridge described in Specification 901,089, a link 26 pivoted on the sleeve valve 12 is surrounded by a spring 24 and hinged to a link 28 rotatable about an axle 30 mounted in a spring cage 31, Fig. 3, the cage being held in position by a spring 32. Housed in the cage is a spring 37 extending between a pin 38 in a slot 39 and a pin 40 on the link 28 and tending to turn the link counter-clockwise, this movement being arrested by a boss 49. As gas is fed into the main body 13, the pressure on the sleeve valve 12 and its follower 14 produces a thrust in the link 26, which at first tends to turn the link 28 counter-clockwise, and is communicated through the boss 49 to the cage 31 to thrust the latter against its spring 32. As the pressure is increased and equalizes in the head, there is a counter-thrust produced on the link 28 through an adjustable stop 41, which eventually rotates the link 28 clockwise, breaking the toggle 26, 28 and allowing the valve to uncover the ports 10. After venting of the cartridge, the springs 24, 32, 37 return the associated parts to their initial positions. The venting pressure can be varied by altering the strength of the springs, adjusting the stop 41, introducing additional shims 34 between spring 32 and the end plug 36 or by moving the plug 36.
