Abstract:
Pump Horn that can easily be used to deliver a blasts of sound. The invention comprises a Chamber that can be filled continuously and indefinitely by a Push/Pull Slide attached to a Suction Piece that when pushed into the Chamber exerts pressurized air that is then pushed through a smaller Tube creating a higher pressure that goes through the Sound Producing Device then through the Amplifying Unit making a loud blasts sound.

       BACKGROUND 
       [0004]    This relates to Pump Horn specifically to the ease of use, environmentally safe and reusable indefinitely manual powered Air Horn Unit. The invention consists of a Chamber that can be filled continuously and indefinitely by a Push-Pull Slide attached to a Suction Piece that exerts pressurized air pushed through a smaller Tube creating a higher pressure that goes through the Sounding Unit and finally through the horn Sound Producing Device making a loud sound. 
         [0005]    Traditional air horns have used aerosols to make the sound blasts. However, the old style air horn aerosols have certain disadvantages. First the aerosol air horns are aerosols and put green house gases into the atmosphere. Second after the gas is used up the gas can needs to be discarded which is a waste of resources and money. 
         [0006]    Our Pump Horn which is manually operated has the first advantage of never needing green house gases to operate. The second advantage of our Pump Horn is it can work indefinitely without needing to purchase refill cans in order to operate. This advantage is very important because the user is assured of proper operation of the unit if needed in an emergency and no risk of the unit not having available gas to operate. 
       SUMMARY OF INVENTION 
       [0007]    A Pump of the pump horn, A Handle attached to the Push/Pull Slide by a screw on nut or glued on securely or molded in plastic to fit on securely. The Push/Pull Slide is made of steel, aluminum or plastic made to be able to slide in and out of the pump and serves as the force to push the air into a Horn which eventually makes the Pump Horn make its sound. The Chamber is made of steel, aluminum, hard plastic or some durable material with holes at both ends to compress air and push out the air at a higher pressure. In this embodiment of the invention the Chamber is a circular solid tube about 2¼ inches in diameter steel with a small hole at one end which the Attachable Member is placed where the Horn can be attached. This is only one embodiment of the invention and the chamber can be be made to any shape or size. The other end there is a Top Holed Cap has a steel lip with four ridges so the Top Holed Cap can be slid and locked on. The other end of the Chamber there is a Compressable Member or Spring that can be made of steel, plastic or any material with a slight spring that assist in helping the Suction Piece go back for the next blow of the horn. The Suction Piece made of plastic, metal or rubber with an indent to put on the “O” Ring which can be comprising a material such as rubber or plastic to help form the seal and push air toward the horn at a pressure. In this embodiment the seal formed by the “O” ring does have some air permeable characteristics but it is preferable to have a tighter seal. The Top Holed Cap can be made of plastic, rubber or metal and in this embodiment of the invention is attached and immovable to the Chamber. The Push/Pull Slide moves in and out of the Chamber causing the air to be forced out of the Attachable Member hole. The Hole  9  is where the air comes out of the Attachable Member  8 . The Attachable Member  8  in this embodiment is a steel threaded screw on piece on the outside of the Chamber and threaded in the inside of Chamber. The Holder is configured with the Attachable Member by nut that screws on the outside of Chamber to hold the Attachable Member in place. There are many variations that the Attachable Member can be attached to the Chamber. including but not limited to being molded directly into the Chamber. 
         [0008]    A horn of the pump horn which will have a Overcap to configured cover the Sound Producing Device. The Amplifying Unit will be conical and made of plastic or metal and configured to amplify the sound made by the amplifying unit. The Tube will be configured to allow air at a pressure from the Chamber to pass through it into the Sound Producing Device. The Tube in this embodiment is made of plastic and threaded so that it can be screwed and unscrewed onto the Attachable Member wherein the Horn is connected to the Chamber. The embodiment of this invention has Tube that is threaded but is not limited to just being connected by threaded pieces to the pump but can include any male/female connection. 
         [0009]    The Sound Producing Device will have an Overcap. In this preferred embodiment of the invention the Sound Producing Device Cap is made of metal and circular and configured to allow a Diaphragm to fit into it. The Sound Producing Device Cap in this preferred embodiment is made of metal and crimped onto the plastic horn. The Diaphragm is a thin plastic circular sheet less than ¼ mm thick. The Tube goes from the pump to the Sound Producing Device emptying air into the Sound Producing Device at Small Hole. The Big Hole then sends out the sound from the Sound Producing Device through Big Hole. This sound is then amplified by the The Amplifying Unit. 
         [0010]    The Push/Pull Slide according to this preferred embodiment. Has a Suction Piece attached to the Push/Pull Slide. The Push/Pull Slide is a metal rod in this embodiment of this invention but can be made of any material that is suitable for providing force to push the Suction Piece in the scope of this invention. In this embodiment of the invention the end of the Push/Pull Slide wherein a Suction Piece is attached by a hole and threaded allowing a Nut to hold the Suction Piece in place. In this embodiment of the invention The Push/Pull Slide will be tapered to a Smaller Threaded Part that can be screwed into the inside part of the Attachable Member An “O” ring that fits into the Suction Piece will assist in building the higher pressure in the Chamber. The Suction Piece will have an indentation for the “O” Ring to hold it on the Suction Piece. The Push/Pull Slide can be extended and inserted into the Chamber to produce the pressure that will go to the Horn through the tube and the Sound Producing Device causing the Diaphragm to vibrate and the horn to produce sound through the Amplifying Device. 
       Operation: 
       [0011]    The operation uses a Push-Pull Slide attached to a Suction Piece that when pushed into the Chamber exerts pressurized air that is then pushed into smaller Tube creating a higher pressure that goes through the Sound Producing Device and finally through the Amplifying Unit making a loud sound. The sound is made because a large amount of air is pushed through a tube and the air vibrates against the tube to make sound. A plastic diaphragm inside the horn oscillates between its open and closed position as the air passes through. The vibration is carried to and magnified by a sound amplifying unit which vibrates at the same frequency. Because the entire horn vibrates that transfer of vibrations to the air makes a loud sound. The Push-Pull Slide then is sprung back by a Compressable member (spring) located in front of the Chamber assisting the Push-Pull Slide to be back in position for the next horn blasts.
