Abstract
Abstract A hand-held pyrotechnic device having a housing containing a quantity of pyrotechnic material, a primer for igniting the pyrotechnic material, a pivotally mounted firing pin for detonating the primer, a spring for actuating the firing pin and a manually actuated push-rod for pivoting the firing pin and increasing spring pressure and then releasing the firing pin after a predetermined amount of pivoting of the firing pin.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
A hand-held signaling device comprising, an outer container opened at both ends, first and second inner containers within said outer container, said first container having a smoke composition therein and being extendable through one end of said outer container, and said second container having a flare composition therein and being extendable through the other end of said outer container, first and second springs for extending portions of said first and second inner containers, respectively, outwardly from said outer container, latching means pivotally attached to said outer container for releasably retaining said inner containers within said outer container, first and second primers for igniting each said composition, first and second firing pins pivotally connected to said first and second inner containers, respectively, for detonating said primers, and first and second manually-actuated means for triggering said first and second firing pins, respectively.
Claim 2
Dependent Claim
140 words
A hand-held signaling device comprising, an outer container opened at both ends, first and second inner containers within said outer container, said first container having a smoke composition therein and being extendable through one end of said outer container, and said second container having a flare composition therein and being extendable through the other end of said outer container, first and second springs for extending portions of said first and second inner containers, respectively, outwardly from said outer container, latching means pivotally attached to said outer container for releasably retaining said inner containers within said outer container, first and second primers for igniting each said composition, first and second firing pins pivotally connected to said first and second inner containers, respectively, for detonating said primers, and first and second manually-actuated means for triggering said first and second firing pins, respectively.
Claim 3
Dependent Claim
49 words
A hand-held signaling device as set forth in claim 1 wherein said first and second manually-actuated means are attached to said first and second inner containers and surrounded by said outer container when said inner containers are retained in said outer container thereby preventing actuation of said firing pins.
Claim 4
Dependent Claim
66 words
A hand-held signaling device as set forth in claim 1 wherein each said manually-actuated means includes a shaft slidably mounted to an inner container and having a barrier attached to one end of said shaft, said barrier being positioned between a firing pin and a primer when said inner container is positioned within said outer container and said barrier being adaptable for rotating said firing pin.
Claim 5
Dependent Claim
61 words
A hand-held signaling device as set forth in claim 3 wherein each said firing pin is biased by a spring wherein after a predetermined amount of rotation of a firing pin in one direction by linear movement of said barrier, said firing pin is disengaged from said barrier and rotated by said spring in an opposite direction to detonate a primer.
