Abstract

Abstract There is disclosed a multi-flashlamp article capable of providing both highly intense audible and visual signals. The article is ideally suited for use as an intrusion alarm and includes a combustible member within the assembly's light-transmittable housing. A prestressed spring actuates the combustible by deforming a tubular primer having a quantity of fulminating material therein. This deflagrating material ignites a second quantity of fulminating material within the combustible's container to effect a suitable audible signal.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 138 words
An article for producing highly intense audible and visual signals, said article comprising: a housing defining a chamber therein, said housing including a base portion and a cover portion having at least one opening therein, at least part of said cover portion being light-transmittable; at least one flashlamp positioned within said chamber of said housing, said flashlamp providing a highly intense visual signal in response to activation thereof, said visual signal passing through said light-transmittable part of said cover portion; at least one combustible member positioned within said chamber of said housing, said combustible member providing a highly intense audible signal in response to actuation thereof, said audible alarm passing through said opening within said cover portion of said housing; and means for actuating said combustible member, said means located within said chamber and adjacent said combustible member.
Claim 2
Dependent Claim 138 words
An article for producing highly intense audible and visual signals, said article comprising: a housing defining a chamber therein, said housing including a base portion and a cover portion having at least one opening therein, at least part of said cover portion being light-transmittable; at least one flashlamp positioned within said chamber of said housing, said flashlamp providing a highly intense visual signal in response to activation thereof, said visual signal passing through said light-transmittable part of said cover portion; at least one combustible member positioned within said chamber of said housing, said combustible member providing a highly intense audible signal in response to actuation thereof, said audible alarm passing through said opening within said cover portion of said housing; and means for actuating said combustible member, said means located within said chamber and adjacent said combustible member.
Claim 3
Dependent Claim 40 words
The article according to claim 1 wherein said flashlamp is percussively-ignitable and includes a light-transmitting envelope and primer tube projecting therefrom, said article further including a prestressed striker spring positioned within said chamber adjacent said flashlamp for activating said flashlamp.
Claim 4
Dependent Claim 21 words
The article according to claim 1 wherein the number of flashlamps is three and the number of combustible members is one.
Claim 5
Dependent Claim 44 words
The article according to claim 1 wherein said combustible member is percussively-ignitable and includes a container and a deformable hollow member projecting therefrom, said means for actuating said combustible member comprising a prestressed striker spring for striking said hollow member to effect deformation thereof.
Claim 6
Dependent Claim 68 words
The article according to claim 4 wherein said container includes an open end, said article further including means for substantially sealing said open end to define a cavity therein, a first quantity of fulminating material located within said cavity, and a second quantity of fulminating material located within said hollow member for igniting said first quantity of fulminating material in response to said deformation of said hollow tube.
Claim 7
Dependent Claim 35 words
The article according to claim 1 wherein said cover member is of boxlike configuration and the number of openings therein is four, each of said openings located in an opposing corner of said cover member.
Claim 8
Dependent Claim 38 words
The article according to claim 1 wherein said cover member is of boxlike configuration and the number of openings therein is four, each of said openings located in an opposing corner of one side of said cover member.
Claim 9
Dependent Claim 35 words
The article according to claim 7 further including a baffle member located on said side of said cover member relative to each of said openings, said baffle members projecting within said chamber of said housing.
Claim 10
Dependent Claim 38 words
The article according to claim 8 wherein the number of flashlamps is three and the number of combustible members is one, each of said flashlamps and said combustible member positioned substantially between a respective pair of baffle members.
Claim 11
Dependent Claim 167 words
A percussively-ignitable combustible member for providing a highly intensive audible signal in response to actuation thereof, said combustible member comprising: a glass container having an open end; sealing means for sealing said open end to define a cavity within said container; said sealing means comprising a thin cup-shaped member sealed about the outer periphery of said glass container; a hollow, deformable member projecting from said container and including an elongated anvil member positioned therein; and first and second quantities of fulminating material, said second quantity being percussively-ignitable and located within said deformable member on said anvil member, said first quantity of the same composition as said second quantity and located within said cavity of said container and spaced apart from said second quantity, said first quantity of material occupying only a minor portion of said cavity, said second quantity igniting said first quantity in response to deformation of said hollow member to cause instantaneous removal of said sealing means and emission of said highly intense audible signal.
Claim 12
Dependent Claim 167 words
A percussively-ignitable combustible member for providing a highly intensive audible signal in response to actuation thereof, said combustible member comprising: a glass container having an open end; sealing means for sealing said open end to define a cavity within said container; said sealing means comprising a thin cup-shaped member sealed about the outer periphery of said glass container; a hollow, deformable member projecting from said container and including an elongated anvil member positioned therein; and first and second quantities of fulminating material, said second quantity being percussively-ignitable and located within said deformable member on said anvil member, said first quantity of the same composition as said second quantity and located within said cavity of said container and spaced apart from said second quantity, said first quantity of material occupying only a minor portion of said cavity, said second quantity igniting said first quantity in response to deformation of said hollow member to cause instantaneous removal of said sealing means and emission of said highly intense audible signal.
Claim 13
Dependent Claim 47 words
The percussively-ignitable combustible member according to claim 10 wherein each of said quantities of fulminating material is comprised of phosphorus, a water-soluble binder, and an oxidizer, the ratio of weights of said first quantity to said second quantity within the range of about 1:1 to about 65:1.
Claim 14
Dependent Claim 38 words
The percussively-ignitable combustible member according to claim 11 wherein said first quantity of fulminating material weighs from about 3.0 to about 20.0 milligrams and said second quantity of fulminating material weighs from about 0.30 to about 3.0 milligrams.
Claim 15
Dependent Claim 36 words
The percussively-ignitable combustible member according to claim 10 wherein said anvil member includes an end portion which extends within said cavity of said container, said first quantity of fulminating material located on said extending end portion.
Claim 16
Dependent Claim 41 words
The percussively-ignitable combustible member according to claim 10 wherein said cup-shaped member positioned about said open end is metalic, said combustible member further including a quantity of adhesive material for securing said cup-shaped member to said open end of said container.
Claim 17
Dependent Claim 14 words
The percussively-ignitable member according to claim 10 wherein said container is comprised of glass.
