FRANKLIN B. HAYS, or INDIANAPOLIS, INDIANA.

CARBURETER.

To aZZ whom it may concern;

Be it known that I, FRANKLIN l3. HAYS, a citizen of the United States, residing at Indianapolis, Marion county, and State of Indiana, have invented and discovered'certain new and useful Improvements in Carbureters, of which the following is a specification. v r

'My invention relates to carbureters and its object isto provide means whereby a" body of air is drawn through a body of hydrocar bon liquid so that the air and liquid will be properly proportioned to provide a highly volatile explosive mixture and the invention also aims to provide a construction having means of a simple and effective characterv for I controlling the passage of the 'air through the carburetor and regulating its volume and that of the auxiliary air and the escaping vapor. j

= With these objects and others in view,'my invention is embodied in preferable form in the construction and arrangement herein after described and illustrated in the accompanying drawings.

In these drawings, section through the carburetor; Fig. 2 a

horizontal section on the line 2 -2 of Fig. 1 gm l?1g.' 3, a horizontal sectlon on the line 3-3 of Fig. 1; Fig. 4, an outside view, partly broken away of the hydrocarbon liquid receiving chamber andFig. 5, a vertical section on the line 5'-5 of Fig. 1. 7

Referring to the drawings, 1 isan inlet adapted to communicate with a source of heated air and servingto admit a body of hot air to the carbureter which constitutes the primary air supply. In the primary air inlet pipe are provided a series of cold air inlets 2 adapted to be controlled by a valve 3 which consists of a circular ring having openings 4 adapted to register with and regulate the size of the openings 2 and which is limited in a range ofmovement by means of set screws5 secured to the inlet plate and extending through slots 6 in the ring valve.

The inlet 1 leads to air chamber 7, the upper wall of which is formed by a partition 8 constituting part of the base of the carbureter and which is provided with a series of openings 9 having beveled or curved seats in which are adapted to be seated ball valves 10 which valves are adapted to be raised 7 Specification of Letters Patent.

chamber 18.

Figure 1 is a vertical yieldingly to their seats by means of a common retaining member consisting of a cap 11 carried at the upper end of avertical movable stem 12, the lower end of which is threaded and engages a sllding block 13 against the upper end of which block or nut bears a spring the upper end of which sprlng bears. against the lower face of the cross partitionplate 8,'whereby the stem 12 and cap 11 are normally pressed downwardly with a ylelding action seats to hold 1 the ball valves to their seats with a yielding spring pressure. Above the valves there .is

"provided'an annular chamber 14, formed by 1 and between the wall of the outer removable .sliell15 of the carbureter and the wall 16 of an inner cylindrical .body.

The chamber 14 communicates by means of annularly disposed-spaced openingsl'i with an annular The .chamber 18 communicates atits lower end by means of annularly disposed spacedaopenings 19 with an annular chamber 20 adapted tocontain wire gauze, the object of which isto effectually break up the particles or" liquid hydrocarbon as the air is drawn through the samefll The chamber 20 communicates'at its lower end with a fuel chamber 21' having a names which fits against and is guided solely by the wallof the fuel chamber and which controls a lever 23 hearing" against the upper;

open the opening 26 leading to the admission pipe 27, through which gasolene or kerosene is adapted to be admitted.

The chamber 20 has an annularly arranged series of openings 28 in its upper wall which lead into an auxiliary air receiving and mixing chamber 29. This mixing chamber is provided with a circular rotatable body 30 having openings 31 coiiperating with openings 32 formed in the wall of the carburetor to admit or exclude or regulate the admission of air into the auxiliary air chamber for the purpose of admitting the necessary quantity of diluting air according to atmospheric or other conditions. The auxiliary air valve formed by this ro tatable body is operated by means of a Worm or screw 33, the screw being carried by a shaft 34 journaled in the wall of the carbureter. r

Above the auxillary alradmltting cham- 7 her is mounted a liquid catching wire screen 85 which is adaptedto prevent large drops of liquid fuel from being carried to the ,outlet and to effect a final subdivision of the liquid for the purpose of facilitating the intimate mixture and increasing :the combustibility of the charge. 7

. Theroutlet 36 of the carbureter'is controlledby an oscillatory flat disk valve 37 having segmental ports 38 adapted to register Withsimilar ports inthe Wall 39 of the V carburetershell. A handle '40 for'operatingzthisthrottle valve through the medium of a rack and pinion is provided. In the-operation of the carbureter the gasolene, kerosene or other liquid hydro-Y carbon fuel will be fedthroughv the inlet pipe27to the fuel chamber 21 and when the fuel has risen in the latter chamber to the level of the openings 19, thefloat 22 will operate-to lift the lever 23 and: close the ber 14 andthence drawn down through the opening 517 into-2 the chamber 18 "where ,it

. 'willpick upth'e liquid hydrocarbon in the bottom of, said chamber and pass into the "chamber 20, whe're it will come in contact with 'a' further body of liquid hydrocarbon, the air thus. becoming 'carbureted. The

' liquid fuel is subjected tosuction and it will 7 Qbefdrawn up. against the wire gauze in chamber 20, thus breaking theliquid into fine particles. .The carbureted air then passes through this. dividingv and suspendf ing wire gauze and out into, the auxiliary air chamber; It will be seen that the air.

drawn through the carbureter meets a body of liquid hydrocarbon. of aifixed quantity dred' and sixteen.

which, is subject to suction and hence only that amount' of the liquid fuelwill be drawn forward to form a charge which the air is capable. of absorbing, thus preventing an excess of the liquid being impelled through the outlet by the mereforce ofthe induced draft of air as in those types of carbureters in which the hydrocarbon fuel 7 is injected into arushing column of air;

The locatiouof-the fuel chamber Within the casing insures a supply of liquid even when the car is running uphill at a steep incline and the form and arrangement of the float valve avoids the use of complicated and expensive guiding constructions for the float. Having thus described my invention, WhatIclaimisr V j j 1. In a carbureter a float, a needle valve operatedthereby,a float chamber, a plurality. of chambers one ofwhich contains wiregauze connected to saidifloat chamber so asto' receive liquid hydrocarbon fuel therefrom, means for passi ng air successively through said plurality of chambers, an

auxiliary'chamber abovesaid float chamber communicating with said gauze containing" chamber, and means for by-passing part of the air through said auxiliary chamber. 2. Ina carbureter a floatganeedle'valve operated thereby, a float chamber a plurality'ofchambers one of which contains'wire gauze connected to said'fioatchamber so as to receive liquid hydrocarbon fuel there from, .means for passing air'successively iliary -chamber above said float'chamber communicating with said gauze containing chamber, means for by-passing part of the air through said auxiliary chamber, and an oscillatory valve for regulating the. outflow,

of fuel from said carbureter.
