Air horn

Claim 2

An air horn, comprising: a. a horn; b. diaphragm means, said diaphragm means being located adjacent the input end of said horn and being sufficiently responsive to lung air pressure to sound said horn thereby; c. a source of compressed gas; d. flow control means, said flow control means connected between said source of compressed gas and said diaphragm and said horn to control the flow of the gas through, and sounding of, Said horn; e. a mouthpiece, said mouthpiece having a bore communicating with said diaphragm and said horn such that blowing through said mouthpiece sounds the horn, said bore being manually closable; and f. actuating means, said actuating means being connected between said mouthpiece and said flow control means, said flow control means being actuated thereby.

Claim 3

An air horn in accordance with claim 1, wherein: a. said flow control means comprises valve means; b. said mouthpiece and said actuating means being movable, said actuating means being connected to said valve means to actuate the same and thereby control the flow of compressed gas through, and sounding of, said horn.

Claim 4

An air horn in accordance with claim 2, wherein: said mouthpiece comprises a button, said button being connected to said actuating means to actuate said valve means.

Claim 5

An air horn in accordance with claim 3 wherein: said valve means comprise a valve member spring-urged into normally closed engagement with a valve seat, said valve means being openable by pressure exerted on said valve member in a direction away from said seat.

Claim 6

An air horn in accordance with claim 4, wherein: said actuating means comprises an extension of said button, said extension extending between said button and said valve member whereby movement of said button correspondingly moves said extension and said valve member.

Claim 7

An air horn in accordance with claim 5, wherein: said valve seat is provided with a central passageway through which said extension passes.

Claim 8

An air horn adapted to be sounded by a source of compressed gas and by blowing by mouth, comprising: a. a horn; b. a source of compressed gas; c. flow control and mouthpiece means, said flow control and mouthpiece means connected between said source of compressed gas and said horn and controlling the flow of compressed gas to said horn, said flow control and mouthpiece means having a bore in communication with said horn for oral use, d. whereby said horn may be sounded by said compressed gas or by mouth by selective use of said flow control and mouthpiece means.

Claim 9

An air horn adapted to be sounded by a source of compressed gas and by blowing by mouth, comprising: a. a horn; b. a source of compressed gas; c. flow control and mouthpiece means, said flow control and mouthpiece means connected between said source of compressed gas and said horn and controlling the flow of compressed gas to said horn, said flow control and mouthpiece means having a bore in communication with said horn for oral use, d. whereby said horn may be sounded by said compressed gas or by mouth by selective use of said flow control and mouthpiece means.

Claim 10

An air horn comprising; a. a horn having b. a vibratory diaphragm, c. a closed air chamber on one side of the diaphragm, d. an open air chamber on the opposite side of the diaphragm, and e. a source of compressed gas in communication with said open air chamber, f. said diaphragm being exposed to both air chambers and being sufficiently responsive to compressed gas pressure and to mouth-blown air pressure in the open air chamber to produce a horn sound, g. flow control means being provided between the source of compressed gas and the open air chamber to control the flow of compressed gas into said open air chamber, h. said flow control means comprising a normally closed valve and actuating means therefor, i. said actuating means including a push-button which is pressed to open the valve and which is released to close the valve, j. said pushbutton having an opening formed therein which communicates with said open air chamber, and being adapted to be held to the mouth so that air might be blown into said open air chamber, k. said opening being located where it would be digitally closed when the pushbutton is digitally actuated to open the valve, l. whereby digital actuation of the pushbutton causes the valve to open and the horn to sound by reason of compressed gas impinging upon the diaphragm, and m. whereby blowing air by mouth into the opening of said pushbutton, without actuating same to open the valve, causes the horn to sound by reason of mouth-blown air impinging upon said diaphragm.

Claim 11

An air horn comprising; a. a horn having b. a vibratory diaphragm, c. a closed air chamber on one side of the diaphragm, d. an open air chamber on the opposite side of the diaphragm, and e. a source of compressed gas in communication with said open air chamber, f. said diaphragm being exposed to both air chambers and being sufficiently responsive to compressed gas pressure and to mouth-blown air pressure in the open air chamber to produce a horn sound, g. flow control means being provided between the source of compressed gas and the open air chamber to control the flow of compressed gas into said open air chamber, h. said flow control means comprising a normally closed valve and actuating means therefor, i. said actuating means including a push-button which is pressed to open the valve and which is released to close the valve, j. said pushbutton having an opening formed therein which communicates with said open air chamber, and being adapted to be held to the mouth so that air might be blown into said open air chamber, k. said opening being located where it would be digitally closed when the pushbutton is digitally actuated to open the valve, l. whereby digital actuation of the pushbutton causes the valve to open and the horn to sound by reason of compressed gas impinging upon the diaphragm, and m. whereby blowing air by mouth into the opening of said pushbutton, without actuating same to open the valve, causes the horn to sound by reason of mouth-blown air impinging upon said diaphragm.
