More particularly, the invention relates to noise making apparatus for protecting crops from wildlife.
Objects of the invention are to provide noise making apparatus for automatically and continuously producing loud noises intermittently in order to protect crops from wildlife by startling foraging animals and thereby frightening them away.
In order that the invention may be readily carried into effect, it will now be described with reference to the accompanying drawing wherein the single FIGURE is a circuit and block diagram of an embodiment of the noise making apparatus of the invention.
The noise making apparatus of the invention comprises a combustion chamber 1.
A gas feeding device supplies explosive gases to the combustion chamber 1. The gas feeding device comprises an electrolyzing system 2 for decomposing water 3 into hydrogen and oxygen. The electrolyzing system includes, in known fashion, an electrolysis chamber 4, a first terminal plate 5 and a second terminal plate 6 in the water 3 in the chamber. The combustion chamber 1 may have a cover 7 hingedly affixed thereto and indicated by broken lines in the FIGURE. The cover 7 is forced open by combustion in the chamber 1. The water is supplied to the electrolysis chamber 4 via a water supply system.
The water supply system comprises a container 8 having an open top 9 and an open bottom 10.
A source of electrical energy such as, for example, a battery 11, is electrically connected to the first and second terminal plates 5 and 6 for energizing the electrolyzing system. A first gas tube 12 and a second gas tube 13 supply hydrogen and oxygen from the electrolyzing system to the combustion chamber. A water pipe 14 returns water from the combustion chamber 1 to the electrolyzing system 2 via the water supply system. More particularly, the water pipe 14 opens into the container 8 through the top 9 thereof.
A sparking device is provided in the combustion chamber 1 for exploding the gases in said chamber. The sparking device comprises a spark gap 18 and a spark coil 19 electrically connected to the source of electrical energy 11. A capacitor 20 is connected across the spark coil 19 in the usual fashion.
A spark control device ignites the sparking device, and, more specifically, the spark gap 18, when the pressure of gas in the combustion chamber 1 reaches a predetermined level. The spark control device comprises a pressure-responsive switch 21 electrically connected between the source of electrical energy 11 and the spark coil 19. The pressure-responsive switch 21 responds to a predetermined low pressure in the combustion chamber 1. The switch 21 is spring-biased and responds to any pressure which it is adjusted to. The switch 21 is adjusted to respond to a pressure in the range of l to 8 ounces per square inch.
A current interrupter 22 is connected in the electrical connection between the source of electrical energy 11 and the spark coil 19.
A starting switch 23 is connected in series with a variable resistor 24 in the electrical connection between the battery 11 and the first and second terminal plates 5 and 6.
The check valves 15 and 17 are open when gas flows into the combustion chamber 1 and are closed when combustion occurs in said chamber. The check valve 16 is closed during combustion in the chamber 1 and open after combustion to return water from said chamber to the container 8.
While the invention has been described by means of a specific example and in a specific embodiment, 1 do not wish to be limited thereto, for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
