Chemical dispensing anti-burglar device

Claim 2

A chemical dispensing anti-burglar Device for use with a pressurized container, the device comprising: a housing, means for supporting said pressurized container in said housing; a fluid passageway extending through said housing having an entry section, means for discharging fluid from said pressurized container into said entry section of said passageway, a reciprocal member slideably mounted within said housing and adapted upon movement to discharge fluid from said pressurized container, an enclosed expansion chamber within said housing, an expansive charge within said chamber, means for causing expansion of said charge within said chamber, said reciprocal member having a surface against which the gases resulting from said expansion react to move said reciprocal member within said housing to cause discharge, a spring activated retaining means for locking said reciprocal member in position to cause discharge after said expansion, a sealing means formed around said entry section and said discharging means and arranged to prevent fluid leakage as fluid is discharged from said pressurized container into said passageway.

Claim 3

The invention of claim 1 wherein said means to cause expansion of said charge comprises an electric element through which an electric current is passed to cause said expansion.

Claim 4

The invention of claim 1 wherein said means to cause expansion of said charge comprises firing member; a means for releasably retaining said firing member in a cocked position displaced from said expandable cartridge; said retaining means including a trigger element; said trigger element being mounted for movement within said body member between an actuation position and a release position; said trigger element in said actuation position in engagement with surface of said firing member to retain said firing member in said cocked position; said trigger element in said release position allowing said firing member to cause said expansion.

Claim 5

The invention of claim 1 wherein said passageway contains a means of producing sound; said means of producing sound comprising a chamber in said passageway to cause vibrations of the fluid in said chamber resulting from oscillations produced as said fluid is flowing through a narrow slot against a knifeedge forming part of said passageway.

Claim 6

A chemical dispensing anti-burglar device for use with a pressurized container including a projecting dispensing spout actuated to emit fluid discharge therethrough upon depresson thereof, a housing, means for supporting said pressurized container in said housing, a fluid passageway extending through said housing having an entry section, a reciprocal member slideably mounted within said housing and adapted upon movement to actuate said dispensing spout, an enclosed expansion chamber within said housing, an expansive charge within said chamber, means for causing expansion of said charge within said chamber, said reciprocal member having a surface against which the gases resulting from said expansion react to move said reciprocal member, a spring activated retaining means for locking said reciprocal member in a position to actuate said dispensing spout and thereby cause discharge after said expansion, a sealing means formed around said entry section and dispensing spout and arranged to prevent fluid leakage as fluid is discharged from said pressurized container into said passageway.

Claim 7

A chemical dispensing anti-burglar device for use with a pressurized container including a projecting dispensing spout actuated to emit fluid discharge therethrough upon depresson thereof, a housing, means for supporting said pressurized container in said housing, a fluid passageway extending through said housing having an entry section, a reciprocal member slideably mounted within said housing and adapted upon movement to actuate said dispensing spout, an enclosed expansion chamber within said housing, an expansive charge within said chamber, means for causing expansion of said charge within said chamber, said reciprocal member having a surface against which the gases resulting from said expansion react to move said reciprocal member, a spring activated retaining means for locking said reciprocal member in a position to actuate said dispensing spout and thereby cause discharge after said expansion, a sealing means formed around said entry section and dispensing spout and arranged to prevent fluid leakage as fluid is discharged from said pressurized container into said passageway.

Claim 8

A chemical dispensing anti-burglar device for use with a pressurized container including a pierceable section, a housing, means for supporting said pressurized container in said housing, a fluid passageway extending through said housing having an entry section, means for piercing said pierceable section whereby fluid may be discharged into said passageway, said means for piercing comprises a projecting spout depending from said entry section of said passageway, a reciprocal member slideably mounted within said housing and adapted upon movement to cause piercing of said pierceable section, an enclosed expansion chamber within said housing, an expansive chargE within said chamber, means for causing expansion of said charge within said chamber, said reciprocal member having a surface against which the gases resulting from said expansion react to move said reciprocal member, a spring activated retaining means for locking said reciprocal member in a position to cause discharge after said expansion, a sealing means formed around said entry section and pierceable section and arranged to prevent fluid leakage as fluid is discharged from said pressurized container into said passageway.

Claim 9

A chemical dispensing anti-burglar device for use with a pressurized container including a pierceable section, a housing, means for supporting said pressurized container in said housing, a fluid passageway extending through said housing having an entry section, means for piercing said pierceable section whereby fluid may be discharged into said passageway, said means for piercing comprises a projecting spout depending from said entry section of said passageway, a reciprocal member slideably mounted within said housing and adapted upon movement to cause piercing of said pierceable section, an enclosed expansion chamber within said housing, an expansive chargE within said chamber, means for causing expansion of said charge within said chamber, said reciprocal member having a surface against which the gases resulting from said expansion react to move said reciprocal member, a spring activated retaining means for locking said reciprocal member in a position to cause discharge after said expansion, a sealing means formed around said entry section and pierceable section and arranged to prevent fluid leakage as fluid is discharged from said pressurized container into said passageway.
