Simulated fire apparatus

Claim 2

Simulated fire apparatus comprising a fuel burner, a supply of fuel and means for feeding fuel from the supply to the burner for producing a visually observable flame at the burner, varying means for varying the visually observable effect of a flame produced at the burner, sound producinG means for simulating the sound of another type of fire burning, and connecting means interconnecting the varying means and the sound producing means for coordinating the relationship therebetween.

Claim 3

The apparatus of claim 1, which further comprises timing means operable to produce substantially simultaneous operation of said varying means and sound producing means at random time intervals.

Claim 4

The apparatus of claim 2, wherein said timing means comprises a pair of actuating means, each of which has an actuating and a nonactuating state, means operatively connecting said actuating means to said varying and sound producing means whereby said varying and sound producing means are actuated only when both of said actuating means are in their actuating states simultaneously, a first operator associated with one of said actuating means operable intermittently to shift said one actuating means from its nonactuating to its actuating state, and a second operator associated with the other of said actuating means operable intermittently to shift said other actuating means from its nonactuating to its actuating state.

Claim 5

The apparatus of claim 1, wherein said varying means comprises means for directing a stream of pressurized fluid against a portion of a flame produced at such burner.

Claim 6

The apparatus of claim 1, wherein said varying means comprises a plurality of nozzles, each adapted to direct a stream of pressurized fluid against a different portion of a flame produced at said burner, and supply means for intermittently supplying such a stream of fluid to certain of said nozzles at random time intervals.

Claim 7

Simulated fire apparatus comprising a visually observable flame portrayer actuated by the supply of an operating medium thereto, a supply of such operating medium and means for feeding such to the flame portrayer, recording player means including at least two output channels and means for introducing a different signal on each channel, with one signal being electrically representative of one type of fire burning sound and the other signal being electrically representative of another fire burning sound, speaker means for said channels and electrical circuit means for each channel connecting the channel to the speaker means for delivering the signal of the channel to the speaker means, and attenuator means connected between the electrical circuit means for at least one of said channels and the means for supplying operating medium to the flame portrayer producing attenuation in the sound produced by the speaker means coordinated with attenuation in the supply of operating medium to the flame portrayer.

Claim 8

Simulated fire apparatus comprising a visually observable flame portrayer actuated by the supply of an operating medium thereto, a supply of such operating medium and means for feeding such to the flame portrayer, recording player means including at least two output channels and means for introducing a different signal on each channel, with one signal being electrically representative of one type of fire burning sound and the other signal being electrically representative of another fire burning sound, speaker means for said channels and electrical circuit means for each channel connecting the channel to the speaker means for delivering the signal of the channel to the speaker means, and attenuator means connected between the electrical circuit means for at least one of said channels and the means for supplying operating medium to the flame portrayer producing attenuation in the sound produced by the speaker means coordinated with attenuation in the supply of operating medium to the flame portrayer.

Claim 9

The apparatus of claim 6 which further comprises manually adjusted control means for regulating the amplitude of the signal in said one channel delivered to said speaker means, and wherein said attenuator means includes means responsive to an adjustment of said control means for changing the attenuation produced by the attenuator means.

Claim 10

The apparatus of claim 6, wherein said attenuator means comprises a signal attenuator producing changes in the signal delivered to said speaker means, a supply attenuator for changing the supply of operating medium fed to the flame producer, and a power-operated actuator for the two attenuators for actuating the two in a coordinated manner.

Claim 11

Simulated fire apparatus comprising a gas burner operable to produce a gas flame, a supply of such gas and means for feeding gas from the supply to the burner, recording player means including an output channel and means for introducing a signal on such channel with such signal being electrically representative of a type of fire burning sound, a speaker and electrical circuit means connecting said channel to the speaker, and attenuator means connected between the electrical circuit means and the means for feeding gas to the burner producing attenuation in the sound produced by the speaker coordinated with attenuation of the gas supplIed to the burner.

Claim 12

Simulated fire apparatus comprising a gas burner operable to produce a gas flame, a supply of such gas and means for feeding gas from the supply to the burner, recording player means including an output channel and means for introducing a signal on such channel with such signal being electrically representative of a type of fire burning sound, a speaker and electrical circuit means connecting said channel to the speaker, and attenuator means connected between the electrical circuit means and the means for feeding gas to the burner producing attenuation in the sound produced by the speaker coordinated with attenuation of the gas supplIed to the burner.

Claim 13

The apparatus of claim 9, wherein said attenuator means comprises a signal attenuator producing changes in the signal delivered to the speaker, a valve for changing the supply of gas fed to the burner, and a power-operated actuator for the signal attenuator and valve constructed to actuate the two in a coordinated manner.
