Abstract

Abstract A protective exploratory signalling projectile adapted to be manually thrown within a darkened area from one location to another during law enforcement maneuvers. The projectile is provided with a light source, means for supplying energy to the source, trigger means operable to control the energy supply to the source, and time delay means for postponing the energy supply for a time interval immediately following the operation of the trigger whereby the triggered projectile may be thrown without illuminating the location of the party throwing it.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 127 words
A protective signalling exploratory projectile for use in law enforcement maneuvers, said projectile adapted to be manually thrown within a darkened area from one location to another, comprising: a translucent casing; a light source in said casing, said source comprising a high-intensity flash bulb, an intermittently operable bulb of relatively low light intensity, and a third bulb continuously and concurrently illuminable with the aforementioned bulbs; a source of electricity; and electrical circuit connecting said last-named course to said bulbs; a switch in said circuit; and time delay means responsive to the closing of said switch for deferring the energization of said circuit and the light source therein for a time interval immediately following said closing whereby the location of the thrower may be concealed during said interval.
Claim 2
Dependent Claim 127 words
A protective signalling exploratory projectile for use in law enforcement maneuvers, said projectile adapted to be manually thrown within a darkened area from one location to another, comprising: a translucent casing; a light source in said casing, said source comprising a high-intensity flash bulb, an intermittently operable bulb of relatively low light intensity, and a third bulb continuously and concurrently illuminable with the aforementioned bulbs; a source of electricity; and electrical circuit connecting said last-named course to said bulbs; a switch in said circuit; and time delay means responsive to the closing of said switch for deferring the energization of said circuit and the light source therein for a time interval immediately following said closing whereby the location of the thrower may be concealed during said interval.
Claim 3
Dependent Claim 100 words
A protective signalling exploratory projectile for use in low enforcement maneuvers, said projectile adapted to be manually thrown within a darkened area from one location to another, comprising: a translucent casing; a light source in said casing; an electrical power source; an unijunction transistor; means including a circuit and said power source for rendering said transistor conductive; a second circuit connecting said power source and said light source; a time delay means including a silicon-controlled rectifier responsive to the conductivity of said transistor for energizing said second circuit and the light source therein; and a pin-actuated switch controlling said circuits.
