Tilt-operated hand held gas powered acoustic device

Claim 2

In combination, a pressurized fluid container having an outlet, valve means mounted in said outlet and having a tiltable stem part, a compressed-gas-operated horn having a body part, said body part having an inlet part, a connection between said stem part and said inlet part, said connection having screw threads on the connected parts and being hollow, a radial extension on one of said parts engaging with a shoulder on the other of said parts after predetermined screwing of said parts tO secure said body part and stem part together, at least one of said parts being made of resilient material permitting distortion for accomplishing said securement, the interengagement and interlocking of said parts providing an improved seal against fluid leakage.

Claim 3

The combination as claimed in claim 1 in which said radial extension is an annular flange on said stem part and said shoulder is formed by an annular recess in said inlet part.

Claim 4

In combination, a pressurized fluid container having an outlet, valve means mounted in said outlet having a hollow tiltable stem part, a compressed-gas operated horn having a body with an inlet passage part, said inlet passage part having a screw thread connection with said stem part for mounting said horn on said stem, said horn body being tiltable to cause opening and closing of said valve means and operation of said device to give a warning sound, and securing means supplementary to said screw thread connection formed on said stem part and said inlet passage part, said supplementary means inter-engaging after predetermined screwing of said connection and upon further screwing automatically acting to secure said horn to said valve means, said securing means being made of deformable material so as to be deformable and releasable on unscrewing and forceable overcoming of said inter-engagement.

Claim 5

In combination, a pressurized fluid container having an outlet, valve means mounted in said outlet having a hollow tiltable stem part, a compressed-gas operated horn having a body with an inlet passage part, said inlet passage part having a screw thread connection with said stem part for mounting said horn on said stem, said horn body being tiltable to cause opening and closing of said valve means and operation of said device to give a warning sound, and securing means supplementary to said screw thread connection formed on said stem part and said inlet passage part, said supplementary means inter-engaging after predetermined screwing of said connection and upon further screwing automatically acting to secure said horn to said valve means, said securing means being made of deformable material so as to be deformable and releasable on unscrewing and forceable overcoming of said inter-engagement.

Claim 6

In combination, a pressurized fluid container having an outlet, valve means mounted in said outlet having a tiltable stem part, a compressed-gas-operated horn having a body part with an inlet passage, connection means on said body part and said valve means forming a connection for mounting said body part on said stem part with one part inserted within the other, means on said body part and said stem part supplementary to said connection means acting after predetermined inter-engagement of said body and stem parts to secure them together, said horn being tiltable to cause opening and closing of said valve means and operation of the horn to give a warning sound, said horn having a cap part and a vibratable diaphragm, said diaphragm being held between said cap part and said body part, and a snap-on connection between said body and cap parts, said snap-on connection comprising an annular projecting means and annular recess means on said body and cap parts which have mating engagement when assembled, at least one of said parts being made of resilient material whereby said parts may be forced together and permanently held in engagement.

Claim 7

In combination, a pressurized fluid container having an outlet, valve means mounted in said outlet having a tiltable stem part, a compressed-gas-operated horn having a body part with an inlet passage, connection means on said body part and said valve means forming a connection for mounting said body part on said stem part with one part inserted within the other, means on said body part and said stem part supplementary to said connection means acting after predetermined inter-engagement of said body and stem parts to secure them together, said horn being tiltable to cause opening and closing of said valve means and operation of the horn to give a warning sound, said horn having a cap part and a vibratable diaphragm, said diaphragm being held between said cap part and said body part, and a snap-on connection between said body and cap parts, said snap-on connection comprising an annular projecting means and annular recess means on said body and cap parts which have mating engagement when assembled, at least one of said parts being made of resilient material whereby said parts may be forced together and permanently held in engagement.

Claim 8

For use with a pressurized fluid container having an outlet valve, a gas-power-operated horn mounted on said valve, said horn having a body part and a cap part and a vibratable diaphragm, said cap and body parts having cooperating interior annular shoulder means and recess means providing a seat for the peripheral edge of said diaphragm, said diaphragm being held between said cap part and said body part and providing a closed chamber between itself and said cap part, and a snap-on connection between said body and cap parts comprising annular projecting means and annular recess means on said body part and cap part which having mating engagement when assembled, at least one of said parts being made of resilient material whereby said parts may be forced together and securely held in engagement concomitantly providing a seal therebetween.

Claim 9

For use with a pressurized fluid container having an outlet valve, a gas-power-operated horn mounted on said valve, said horn having a body part and a cap part and a vibratable diaphragm, said cap and body parts having cooperating interior annular shoulder means and recess means providing a seat for the peripheral edge of said diaphragm, said diaphragm being held between said cap part and said body part and providing a closed chamber between itself and said cap part, and a snap-on connection between said body and cap parts comprising annular projecting means and annular recess means on said body part and cap part which having mating engagement when assembled, at least one of said parts being made of resilient material whereby said parts may be forced together and securely held in engagement concomitantly providing a seal therebetween.

Claim 10

The combination as claimed in claim 5 in which said body part of the horn has a flared trumpet portion surrounded at one end by a peripheral portion providing a secondary chamber therebetween, and a plurality of internal stiffening webs in said secondary chamber.

Claim 11

The combination as claimed in claim 6 wherein said trumpet portion is provided with a plurality of external radial stiffening webs running lengthwise of said trumpet portion.

Claim 12

The combination as claimed in claim 6 in which said body portion of the horn has a lateral extension with a passage leading from said outlet valve to said secondary chamber, and a metering passage between said lateral exteNsion passage and said secondary chamber.
