1'0 all w/wm it may concern.-

Be it known that I, AUGUSTUS LEANDER ELLIS, a citizen'of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new liquids from which inflammable gas may be made.

An ob ect of the invention is to provide positive, direct, and simple means for making from gasolene or other suitable liquid, a gas of uniform quality, by supplying in correlative proportions to the carbureter, air

and inflammable liquid, the former being supplied continuously and under uniform pressure while the gas is being used, and the .latter being supplied intermittently in appropriate quantities at intervals during the same time, thereby causing the air to always act upon a body of fresh liquid, and .to-accomplish this in a most direct and positive way and without any pump for the inflammable liquid. B y this means the same quality of gas may be produced throughout the entire period in which the machine is inoperation, and the liability to get out of order is brought to a minimum.

In order to secure an absolutely uniform 4 gas at a uniform pressure at all times, it is necessary to supply the air and inflammable liquld to the carbureterunder uniform conditions for each, and in order to do this it is necessary that the air be delivered to the carbureter at ap actically constant and uniform pressure, and that the liquid be supplied under sullicient pressure to spray it upon the absorbent material in the carbureter, )ut in such small quantity as to prevent flooding of the carburetor and overcharging the air. I therefore employ an aircmcter between the air pump and the carbure tor as a part of the means for supplying the liquid and air in. correlative proportions; and

i. pro vide a gravity feed and a weighted rotary outsellvalve to control the flow therefrom to the carburetor, and I- operate said cut-oil by connection with the belief an air pump.

Although my gas machine is ada ted for lug gas from any suitable liquid I shall after refer to liquid liiydrocar'bon as the The invention is applicable in gas ma chines provided with an air pump by which the air to be carbureted is supplied, and. re-

lates to carbureting means, to means for supplying hydrocarbon and air in correlated proportions, and also to various features, con-i binations and parts hereinafter particularly described.

Theinvention may be carried out in different forms and styles of machines, and I shall illustrate the same in one of the forms I deem most desirable.

The carbureter in this invention is of novel construction and is supplied with liquid hydrocarbon that is directly under the control of the air-supplying means. The valve to control the supply of liquid hydrocarbon may be operated by the movements of an airometer or by the movements of an air pump, or by other means I shall illustrate the invention as applied in a machine in which the hydrocarbon sup ply is controlled by the movements of an automatic air pump operated by water supplied under .pressure to raise the bell or receiver of the air pump and then automatically discharge to allow the receiver to descend. This form of pump being Well known, will not be illustrated in detail herein.

The accompanying drawings illustrate the invention in the form 1 at present deem preferable.

which is provided with a vertically-movable receiver or bell 2 that is ooerated up and down in the usual way to pump air through to the air chamber 9.

a pipe 3 to an airometer 4 for equalizing and keeping at uniform pressure the air which isthence delivered through a pipe 5 to the lower part ofia carbureter 6. This uniform pressure of the air is necessary order to supply the air and hydrocarbon to the carbureter in correlative pro ortions. Said carbureter comprises a ,shel 7 provided at the top with a hydrocarbon reservoir or tank 8, and at the bottom'with an air chamber 9.

10 is a diaphragm or partition forming the bottom of the tank 8, and 11 is a diaphragm forming the bottom of the air chamber 9.

12 is a foraminated partition or support above the air chamber 9 for sustaining a layer of sponges 18.

14 is an air distributer in the form of a hollow cylinder or cap open at its lower end to receive air from the pipe 5 and distribute it Said pipe 5 extends up into the cap 14 so that the air which enters the carbureter is forced to flow from the end of the pipe 5 downward and outward at the bottom of the cup to be evenly distributed to the under side of the lower sponges 13 which are carried by the foraminated partition 12. V

15 is a porous body which may be formed of excelsior above the layer of sponges i3 and surrounding and overlying the upper end of the air distributer 14, I

16 designates a top layer of sponges, and 17 a foramin'ated partition or screen. above said'top layer, preferably made of Wire netting.

18 is a spreading device for distributinr liquid hydrocarbon over the netting an porous filling.

19 is a valved conduit leading from the reservoir 8 above the'partition 10 and opening into the carbureting chamber 20 through the hvdrocarbon spreader or star 18 which delivers the hydrocarbon to the porous bodies 16, 15, 13, beneath the same, and all located in the carbureting chamber.

' 21 is a gas outlet-main leading from the top of the carbureting chamber 20 to the burners, not shown. 7

22 is an equalizing pipe communicating between the carbureter chamber 20 and the top of theliydrocarbon reservoir 8 to supply the vacuum in the hydrocarbon reservoir, and. equalize the pressure on opposite sides of the diaphragm 10 as the hydrocarbon flows from chamber 8 into chamber 20;

The purpose of providing a layer of porous 1naterial,preferably sponges,then a layer pension the smaller and-lighter particles of ydrocarbon, while the=heavier and larger particles of hydrocarbon will pass on through the fibrous material which will divide and break them into smaller bodies, and the last or lower layer of porous material will hold them in suspension, thus .placing the entire amount of hydrocarbon supplied at one action, to the carbureter, in sucha position that the air as it is supplied to the carbureter at a lower layer of porous material, will come in contact first with the heavier or less volatile part and afterward with the lighter, more volatile parts of the gasolene, and as it passes through the various layers of porous and fibrous material, will become charged with I sufficient hydrocarbon to produce an even and fixed gas; The hydrocarbon being only supplied in -proportion to the air, does not permit thef air to be overcharged with the ydrocarbon and compels the air to act more evenly and thoroughly on the hydrocarbon, and

same;

An intermittent automatic hydrocarbon cut-oil device is provided in the form of a feed valveand operative parts connected therewith, which will now be described.

23 is a feed valve for controlling the flow of so, insures a better carburizing f-the ICO liquid hydrocarbon through the valved conduit- 19, the same being operated by a suitable-trip 24 having a bell-crank or lever 25 loosely mounted on the valve-stem and adju'stable overbalancing weights 26 and 27' adjustably mounted respectivel'y'on arms 28 and 29, which arms are connected with an operating-arm 30 and with a sleeve 31 adjustably fixed on valve stem 23 by set-screw 32. Integrally united with said sleeve are the three arms numbered 28, 29 and 30, two of whih'h,namely 28 and 29, are provided with counterweights 26 and 27, previously, referred to. These weights are adjustable on said-arms by means of set screws 30. On the same stem 23 is fulcrumed a bell-crank or lever 25 provided at one end with an'elongated slot 34 and having a lug or pin 34 at the other end which is arranged to extend between and alternately engage the=arrn 30 and the arm 29. the bell-crank for the purpose of allowing thr operating-rod 35 to extend therethroug'h. Upon this rod are mounted adjustable members or buttons 36 which, when contacting with the lever or bell-crank 25, on the rise and fall of the pump-bell, cause the pin or lug 34 to liftthe weighted arms up to and The slot 34 is provided in over the center of gravity, whereupon the same will fall and either. close or open the valve.

The operation of the rod 35 is controlled entirely by the movement of the air-pump which supplies air to the airometer from which theair is introduced into the carbureter previous to mixing it with the gasolene vapors. The upper end of the rod 35 is loosely mounted in bracket b in order to al low a certain amount of play of said rod which the movement of the bell-crank arm necessitates.

The stem 23 of the valve is screw-threaded and engages the screw threads provided on the interior of the shell or chamber 37 of the valve casing, whereby by the movement of the weighted extremities on the sleeve, it travels endwise either in' one direction or the other according entirely to the movement of the air-pump.

To regulate the quantity of hydrocarbon delivered from the tank 8 of the'carbureter, I

provide a valve 33 located on the supplypipe 19 which communicates with the gas chamber 20. Thus the volume of the flow may be regulated by manual operation of said valve 33, and the period of such llow will be governed automatically by movement of the air-pump up and down which operates the bell-crank loosely mounted upon the stem of the valve, which in turn operates the weights on the valve-actuating arms and sclilopens and closes the feed valve automatica y.

c is a ca ed filler i e for sn 1 in h drocarbon is? the tank? p P y a y The star 18 may be formed with a gas body 38 and radiating arms 39 of perforated pipe sections provided with caps 40 at their ends.

The perforations 41 for spraying the hydrocarbon are arranged along the sides of said ipes, so as to spray the hydrocarbon, eve y over the screen 17. I

42 is a valved outlet .i'er drawing oll' any hydrocarbon that may pass through to the bottom of the air chamber 9.

When the machine is properly installed and connected with the house piping for the distribution of the gas to the places of consumption, the lighting of the lights, stoves or grates causing or opening a vent for the escape of the gas starts the machine by causing the air to pass from the airometer into and through the carbureting chamber, where it comes in contact with the hydrocarbon, causing the air to become-charged with the hydrocarbon, so. forming. gas which passes out through the outlet pipe 21 to the places of consumption.

The descent of the airometer operates a lever, not shown, which in the well known way operates a valve, not shown, allowing intofthe cylinder in the air pump, causing i the air-pump to act and automatically suply the airometer with air to take the place of that which has been used in making the gas, which has been consumed. This action will continue as long and in the proportion of theamount of gas used, and the turning off of the lights, stovesor grates will stop or close the vent and so stop the operation of the gas making process.
