To all 'whom it may concern.'

Be it known that I, WILLIAM I-I. MCAN- DREWS, a citizen of the United States of America, and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Carbureters, of which the following is a specification.

My invention relates to carbureters for the generation of gas for heat, light and power, and is well adapted for use on automobiles propelled by internal combustion motors. l

A special object of my invention is the provision of an improved carbureter adaptedmore particularly for use on automobiles driven by internal combustion motors, and the provision of certain details and features of improvement tending to increase the general eliiciency and serviceability of a carbureter of this particular character. f

To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a vertical section, on an enlarged scale, of my improved carbureter, showing certain connections and parts 1n side elevation. Fig. 2 is an enlarged detail of the valve controlling the supply of hydro-carbon to the carbureter. Fig. ,3 is a horizontal section on line 3 3 in Fig. 1. Fig. 4 is a horizontal section on line 4 4 in Fig. 1. Fig. 5 is a horizontal section on line 5 5 in Fig. 1. Fig. 6 is a horizontal section on line 6-6 in Fig. 1.

Referring more particularly to Figs. 1 to 6 inclusive, my improved carburet-er J comprises a tank or receptacle 7' adapted tohold a suitable quantity of oil or hydro-carbon j. The said tank or receptacle has a cover j, and this cover and the tank or receptacle are separated by a centrally apertured dia phragm ja. A plate or disk j* 1s hung from the central portlon of the said diaphragm at a point below the central aperture thereof, and connected with the said aperture by means of' a cylinder of wire auze j, or other suitable reticulated materlal. A little farther down, the slightly conical diaphragm j is connected with the lower side of the disk j* by another cylinder or rin of wire gauze or other reticulated materia jf. It will be seen that this diaphragm j has a central opening leading up into the interior of the gauze or reticulated cylinder j?. An

oil inlet pipe j@ leads to the bottom of the rereceptacle and supplies the interior thereof with suitable quantities of oil or hydrocarbon. It is evident that the pi e js can extend downwardly on the outsi e ifdesired, and discharge into the bottom of the receptacle, or through the side near the bottom, so long as the oil is introduced into the tank at or near the bottom thereof. Just above the nozzle or outlet portion ofthis pipe js, there are provided a couple of diaphragms j and jm arranged one above the other, and the upper diaphragm j being provided with perforat-ions ju. The peripheral portions of these two diaphragme are rigidly separated by a ring j having peripheral' ring openings 7'13. The lower diaphragm j is preferably imperforate. In addition, the upper diaphragm j is provided'with a centrally arranged aperture to which is suitably connected an air inlet pipe j, the latter leading to the side of the receptacle and ultimately connectin with the air supply or ressure pipes jl. round its outer. edge, t e diaphragm j is provided with small openings j. At its top, the said carbureter is provided with va gas oflt'ake or pipe j". With this arrangement, the air entering the recept-acle through the pipe j flows into the chamber provided between the diaphragms j and jl". Theair then escapes through the apertures or perforations j and j, where it then mingles with the body of oil or hydro-carbon j. -The gas thus formed then passes upwardly throughv the central opening in the diaphragm j, where it then passes upwardly throu h the screen or-reticulated cylinder j". A er this, the gas passes through the sides of the screen or reticulated cylinder j, and then upwardly through the central opening in the diaphragm ja. From thispoint the gas escapes through the pipe or oftake jl". vIn this way, a superior form of gas is manufactured in said carbureter from air which is admitted 'directl to the hydro-carbon. -After this,

as. exp ained, the' gas is forced to pass' upw'ardlylthrough successive screening or v more orlessiinely reticulated means before lit is allowed to escape for use. The supplyA fof oil to the carbureter is controlled by a needle valve j connected inthe oilsupply pipe j, Itwill be seenthat this valve 1s operated by a spring-held pistonjz", e

. bureter, the greater the supply of air thereto, and vice versa. In .this way, the said `C arbureter can' be run on easy'pressure, or can be crowded to its Afull capacity, without requiring anyl manual adjustment of any of its parts or controlling devices. The air passing through thebody of oil impoverishes it to-a considerable extent, but the new supply of oil being furnished to the chamber below, the air opening immediately enriches the upper portion of the oil body, so

that the gas produced is of a substantially uniform quality. The oil supply tank (not shown) is arranged in any suitable position and is connected by apipe with theoil supply pipe 7'19 leading to the carbureter.

With further respect to the carbureter, it will be seen that the apertures j permit any oil of'condensation occurring above the diaphragm 7'6 to ow back to the receptacle containing the main body of oil or hydrocarbon. A particular object of the carbureter .I is to preserve at all times the correctproportion of air and oil.- The air pressure is bound to vary somewhat, re# gardless of the particular. use of said carbureter, and with the automatic valve. the correct proportion will always be retained. In other words, there is a certain proportion which gives the most combustible mixture which can be produced, and the automatic valve preserves this proportion at all times. Furthermore, in the carbureter fresh oil is constantly supplied at a point below, so that it rises and keeps full, rich oil at the top of the body of oil in thegenerator. Inthis way, the air is not permitted to impoverish the oil, so to speak, the oil through which air passes always being of the same gas-making value or quality.

One of the important features of the general construction consists in increasing the power of the engine without increasing the :cooling the engine. vThe speed. This is done cylinder of the engine.

For example, this can be done by closing off the surplus air from the pump,-that is, the air which is Iordinarily escaping into theatmosphere and which is not used for ump Supplies certain amount of air, an a certain portion of this air is used in cooling the engine,

and what is left can be used for any other vpurpose whatever. As stated, this surplus air can .be thrown. into the carbureter, so as to increase the pressure at this point and thus supply the gas under pressure to the engine. Of course, the gas supplied to the engine is always under pressure, but the important thing is to increase the pressure in order to increase the power of the engine without increasing its speed. Ordinarily, and' at all times, theair supplied from the pump goes partly to the engine to cool the same, and partly to the carbureter, and over and above this quantitythere is a surplus which is going anywhere, wherever .it is needed, or to the atmosphere if there is no way in which it can be used.

It is obvious that my improved carbureter can be used forvarious purposes and in variousconnections wherever gas is required either for lighting, heating or the development of power. For this reason, I do not limit myself to the exact details shown and described. d
