Application filed March 20, 1908. Serial No. 422,365.

gas, the object of the invention being to provide a simple, reliable and safe machine winch operates automatically and is maintamed 1n operation by ordinary city water ressure, the machine automatically controling the supply of water to the machine or apparatus which takes care of itself and ef fects the proper admixture of air and gasolene, delivering the same under the necessary pressure to the gas service pipe leading to the different parts of the building where the gas is to be utilized.

With the above general object in view, the invention consists in the novel construction,

combination and arrargement of parts asherein fully describ illustrated and claimed.

In the accompanying drawing :-Figure 1 is a vertical sectional view of. the complete apparatus. ig. 2 is an enlarged elevation of the air supply tank or air pump, looking from the side opposite 1. Fig. 3 is an enlarged vertical sectional view of the carbureter, showing the parts adjacent thereto.

Fig. 4 is a plan view of the carburetor. Fig- 5 1s a detail view showing the reticulated?- former or core of the carburetor and the manner of applying the absorbent material? thereto.

Referring to the drawing, 1 designates the gasolene supply tank which is ordinarily buried in the ground at a suitable depth, as shown in Fig. 1, 2- representing the filling pipe which extendsfrorn the tank upward to. the surface of the ground where it is provided with a sealing cap 3.

In the upper portion. of the tank L is placed adiaphrogin 4 which divides olfthe upper portion of the tank into a carbureting chamber 5- which, as illustrated in 3,

material which is shown at 10. E terial is preferably in the form of absorbent is provided with a large number of perforalllOHS 6 just beneath the carburetor, which perforations allow the air in the tank to pass upward through the carburetor, 7 designating the air pipe which enters the tank 1 at a point below the diaphragm las shown in 1 The diaphragm 4' is also provided ;with a central opening through which the filling pipe 2 passes'as shown. in Fig. 3

and indicated in Fig, 1.

The earbureter comprises a reticulated or meshed wire fabric former or core 8 with proj eating, points 9 for holding the absorbent This mawicking as shown in Fig. 5, composed of any desired. number of strands, the wick bein wrapped around the projecting points 9 o the former which is primarily in the shape of a strip oi any suitable length according to the finished size of the carbureter. After applying the wicking or absorbent material to the former or core, the latter is wrapped or rolled in the form of a coil'as shown 1n Figs. 3 and l, a central aperture being left "for the passage of the filling pipe 2. The carbuo-reter also comprises an encircling rim or casing 11 which imperforate, and also a perforated cover 12 which acts as a distributing agent tor the asolene, the latter beingconducted to an discharged upon the carburetor by the gasolene pipe 13 as shown in Fig. 3 which enters the tank 1 just above the carburetor. The perforations in the cover L 12 are as shown formed by punching through the cover item the underside thereby leavupstanding projer ztions or nipples 14.

which cause a certain quantity of the asodone, the efiect being to distribute the gasoabsorbent material 10 becomes saturated at all points of'the gasolene. The air passmg upwardthrou h the carburetor takes up the wasol ene and the resultant gas or carbureted air passes out. through .a gas p1pe 15 communicating with the top of the carbureting chamber 5 as seen in Fig. 1.

l6 designates a bell which is mounted to lene to behold on the cover until it fin s its -way simultaneously to all of the perforalene toall parts oi the carburetor so that the move up and down in a tank 17 arranged at a suitable point, the same being water sealed in the tank as shown and provided with a suitable depressing weight 18. Extending centrally upward within the bell 16 and tank 17, is a. hydraulic bell lifting device comprising a tubular casing 19 in which operates a piston (not shown), the piston rod 20 of which extends through the upper end of the casing 19 and is connected to the bell, as shown in Fig. 1. Communicating with the base of the casing 19 is a water inlet pipe 21 connected with the city main so that water under pressure is supplied to the hydraulic lifting device 19, suitable valves, (not shown), being arranged in the base of the casing 19 which operates to alternately raise and lower the bell 16 until the water supply is cut off as will hereinafter a pear.

Adjacent to the air inlet end 22 of the air pipe 7 there is arranged an air inlet check valve 23 which opens inward. When the bell 16 rises, it acts as a suction pump, drawing air in past the valve 23 and up through a vertica extension 24 of the air pipe which opens into the air space of the bell. As the bell 16 descends, the air drawn into the same is expelled through the extension 24 and passes by another check valve 25 and through another vertical extension 26 into the air space of a second vertically movable bell 27 constituting the air reservoir. The bell 27 of the air reservoir is mounted in a casin 28 and is water-sealed therein as shown in ig. 1 and in the downward movement of the bell 27, the air under pressure in said reservoir is forced through the upstanding extension 26 into the air pipe 7 and through said pipe into the gasolene tank 1, the air being unable to get past the check valve 25.

29 designates an air regulating valve arranged at a suitable point in the air pipe 7.

The bell 27 is provided with asuitable depressing weight 30 and is also shown as provided with guide rollers 31 whichmove in engagement with a guide frame 32 connected with the casing 28. The bell 27 is provided with a projectin arm 33 having an openin for a rod 34 which connects with the end 0 a valve lever 35 attached to the stem of a water control valve 36 in the water inlet pipe 21. The rod is provided with adjustable nuts 37 and 38 at opposite sides of the arm 33, acting as shoulders which strike against the arm 33, so that when the bell 27 reaches the upper limit of its movement, it

pulls on the rod 34 and operates the valve 36 to cut off the water supply. As the bell 27 descends, it operates on the lower shoulder 38 to again open the water control valve 36, thus rendering the machine automatic in operation.

Connected with the casing 17 of the air supply tank or pump is a gasoiene pump comprising a tubular casing 39, a suction piston 40 working therein and a piston rod or stem 41 which passes out through the upper end ofthe casing 39 through an arm 42 carried by the bell 16, the stem rod 40 having adjustable shoulders 43 and 44 arranged at opposite. sides of the arm 42 and adapted to come in contact therewith. The gasol'ene pipe 13 communicates with the lower end of the casing 39 as shown in Fig. 2 and is provided at opposite sides at the point of communication with check valves 45 and 46 which open in the same direction.

47 designates the suction portion of the gasolene ipe which communicates with the bottom of the gasolene supply in the tank 1 as shown in Fig. 1, said p pe being provided at a suitable point with a check valve 48 which prevents the return of the gasolene to pipe 7 passes upward through the carbureter and the gas passes outward through the pipe 15 to the burners, one of which is shown at 49.

From the foregoing description it will be seen that the apparatus is entirely automatic,

requirin no further attention than the mere filling o the gasolene supply tank 1. It will be observed that the bell 16, the tank or casing 17 and the air supply pipe extension 24, in connection with the hydraulic bell operating device constitute in effect an air pump which supplies the air reservoir bell 27, while the latter acts to force the air into the gasolene supply tank 1 under the requisite pressure to carry the gas through the service pipe to the points of use.

Having thus described the invention, what is claimed as new, is

In carbureted air apparatus, a gasolene storage tank closed on all sides and at top and bottom, a perforated diaphragm dividing of]? the upper portion of said tank to form a carbureting chamber which communicates with the storage compartment beneath the diaphragm, a carburetor embodying in connection with said perforated. dia phragm a meshed wire former or core supported on the diaphragm and wound into the form of a coil having projecting points at top and bottom, absorbent wicking held between the convolutions of the coil and wrapped upon the points thereof, a perforated cover resting on said coil and having upstanding nipples around the perforations therein, an imperforate rim or casing encircling the carbureter and projecting above In testimony whereof I aflix my signature the cover to form an upstanding flange, in presence of two Witnesses.
