ing devices and a special object of my improvements is to combine with a sprayer an automatically acting gas pump actuated by internal combustion and in this way to produce and maintain a gas ressure in a receptacle. This pressure belng the immediate liquid actuating means.
I accomplish this object in the device illustrated in the accompanying drawing' which is an elevation partly in section of an apparatus embodying my invention, the electric circuits and apparatus being shown diagrammatically.
a a is a tank capable of holding the considerable pressure used to actuate the liquid which is to be sprayed upon trees. b is the pipe through which the liquid is impelled, this pipe opens toward the bottom of the tank a and is provided with a foot valve c. The air or gas in the space d above the liquid e in the tank a is 'compressed to a considerable pressure. f lz, j is a pipe or passage extending vertically at j having an elbow at f and extending horizontally into a tank a, at h. g indicates apertures formed through the wall ofthe pipe f h j at the top of the portion k and just within the wall of the tank a. 1I is the combustion chamber. o is an inwardly opening check valve controlling the induction port to the combustion chamber fi. n represents a conventional priming device. m is a carbureter. k is a pipe connecting the carbureter with the induction port of the combustion chamber i. g is a diaphragm chamber connected on one side of the diaphragm by a small passage g2 with the chamber i and on the other side by a pipe t with the spaced. p is a sparln'ng plug. s is a battery and the conventional spark producing electrical apparatus is represented diagrammatically, connecting the battery s and plug p. g3 is a diaphragm in the chamber g.
Speciicat'ion of Letters Patent.
Patented Mar. c, 1917 1' is a rod extending from the center of the diaphragm g3 at rlght angles thereto and adapted to slide through an" aperture through the wall of the chamber g. r2 is a contact 'pomt with which. Vthe rod 1- is adapted to make contact to completea circuit to cause a spark in the combustion chamber z.
u is a spring adapted to put an adjustable` pressure upon the rod r.
The operation of the above described' device is as follows:
A little gasolene may be inserted in the i combustion chamber i through the apparatus n and a small air pump may be fitted to said apparatus so that a combustible mixture under some pressure is` created in the 'chamber i. The pressure due to the head of liquid in the tank a forces the diaphragm g3 outward making contact at r r2 and causing a spark in the combustion chamber z' which ignites the mixture therein. The pressure rises in the chamber 'i forcing the liquid through the pipe f I1, j forcibly into the tank a and when the liquid` has passed the aperture g part of the gases under pressure pass through said apertures and rise through the liquid to the space d. The liquid is carried forward by its inertia, and the gases in the pipe f h j and the chamber i are cooled, thus producing a partial vacuum in the chamber c', which causes the valve o to open and draws a combustible mixture through the carbureter m. The liquid returning in the pipe f Il, j compresses the mixture in the combustion chamber i and again presses out the diaphragm g3 completing the electric circuit, thc
charge 1s again ignited in the chamber z' and the operation is continually repeated. By this means any desired pressure may be created and maintained in the space d. The liquid in the pipe f h j forms a piston having considerable inertia.
What I claim is:
1. In a sprayer, the combination of an air tight tank, liquid therein, a combustion chamber, said combustion chamber 'communicating with said tank below the liquid level therein, and means for causing explosions in said chamber whereby the gas is transferred under pressure from said combustion chamber to said tank.
2. In a sprayer, the combination of an air tight tank, spraying liquid therein, a combustion chamber, said combustion cliamber communicating with said tank below the causing repeated explosions 'in said chamber whereby the gas is ,transferred under pressure :from said combustionchamber to and tosaid tank below the level of the liquid v therein, said passage being provlded wlth an 1o aperture through its wall opening to said tank, and means for causingan explosion in said combustion chamber whereby the gas from said explosion chamber 1s caused to pass through said aperture into sald tank.
4. The combinationof an air tlght tank, an explosion chamber, a passage communieating with said explosiom chamber and tank, a piston having inertia 1n sald passage, means for producing an exploslon 1n said chamber to propel said piston toward said tank, and means for putting said combustion chamber into communication with said tank so as to cause the gas to pass from the eX- plosion chamber to the tank after the exan explosion chamber, a
plosion has occurred in said chamber and means for retraeting said piston.
5. The combination of an air tight tank,
passage communii eating with said exploslon chamber and tank, a piston having inertia in said passage, means for produclng an exploslon l1n said chamber to propel said piston toward saidl tank, an aperture through the wall of said passage communicating with sald tank and adapted to be uncovered by said piston 1n its stroke under the impetus of said explosion and means for retracting said piston.
6. The combination of a receptacle adapted l to contain compressed gas, a combustion chamber, a communicating passage between said combustion chamber and receptacle, a piston having inertia adapted to reciprocate 1n said passage and in lts motion toward said receptacle to open a passage for compressed gas between said combustion chamber and said receptacle, means for causing an explosion in said chamber to propel said piston toward said receptacle, said piston being adapted to be forced back by the action of said compressed gas whereby a charge of explosive mlxture is drawn into the combustion chamber and compressed on said return stroke of said piston.
7. The combination of a receptacle adapted to contain compressed gas, a c mbustion chamber, a communicating passage between said combustion chamber and receptacle, a
Vtoward said receptacle,
terasse liquid in said receptacle said passage being below the level of sai liquid, means for 'causmg an explosion in: said .combustion to contain compressed gas, a combustion chamber, a communicating passage between said combustion chamber and receptacle, a piston having inertia adapted to reciprocate 1n said passage and in its motion toward said receptacle to open a4 passage for compressed gas between said combustion chamber and said receptacle, means for causing an explosion in said chamber to piipel said piston sal adapted-to be forced back by the action ot said compressed gas whereby ,a charge of explosive mixture is drawn into the combustion chamber and compressed on said return stroke of said piston, and automatic means for igniting the compressed charge in the combustion chamber.
9. The combination of a receptacle adapted to contain compressed gas, a combustion chamber, a communicating passage between said combustion chamber and receptacle, a liquid in said receptacle, said passage being belowthe level of said liquid, means for causing an explosion in said combustion chamber to propel the liquid in said passage toward said receptacle, the water being returned by the action of said compressed gas, and means whereby al passage forthe gas between v4said chamber andV receptacle is established when the water in said passage moves toward said charge of explosive mixture is drawn into the combustion chamber and compressed on said return motion of said water whereby a charge of explosive mixture is drawn into the combustion chamber and compressed on said return motion of said water, and automatic means for igniting the compressed charge in the combustion chamber.
