ginnastica me cimaen or the French Republic., residingJ at ullins? in France, have invented certain inea anni useful improvements Carlin- :esters for lisplosicanistersy olivhich the following is specificstiom y is invention relates to an in'iprt'ivecl cerhi. er for explosion'niotors ofi the automatic suction type, as distinguished trom the mechanical' control type. lt also relates particularly to that type of suenen Carnureter wherein two sources of liquid fuel supply are used. one suhiect to the suction and the other delivering an approximately constent amount oi liquid fuel per unit oi time; such. as set forth in my Patent No. 9D dated Becenxher 29,

i l .v l The invention. consists broadly 1n uniting the liquid fuel supplied from the said. two sources9 and thereafter supplying airtliereto to forni a proportioned emulsion which will yhe conducted to a further air supply by which the emulsion is diluted to the proper extent tov form an explosive mixture and then sucked to the engine.

ln the preferred form of my invention the liquid fuel flowing; from the constant level reservoir is divided into two streams, one

stream Howing to a well 'communicating' with the atmosphere, and; the other owing directly to a nozzle subject to suction. These 'two streams, one of which will deliver an approximately constant volumeper unit of time, while the other will vary according to suction, are joined together in a suitable channel ancl thereafter a relatively small amount of air is supplied to the combined amounts of liquid fuel to form an emulsion. T he conduit in which this emulsion is formed leads into a main air supply channel subject to the suction of the engine and preferably being of Venturi Jterm, provided with the usual throttle. y

This apparatus gives the advantage over that ot xny previous patent, that the liquid fuel is not vaporizecl at the time the emulsion is foi-ined., and consequently the heat lost by1 vaporization'ldoes not occur until the emulsion enters them'ain air conduit, which naturally is nearerthe engine than it would. loe in my previousfpatent apparatus. Y,There is also less liability ot the liquid fuel over flowing and spilling than in my previous apparatus.

Patenten Eier@ '29 'ltil ln the drawings, Figure is a diagrama Fig. 2 is a similar view showing; a moolileclform of the connection between the emulsion tube anti the Venturi or main air passage9 and Fig, 3 is a view similar to la. portion l showing;- a motlied form.,

ln the torna of Fig. l, i) is the constant level reservoir freni which the fuel ows to the main nozzle ain the ordinary manner. Liquid fuel also flows from this constant level reservoir to the calibrated oriiice c and enters the well d, the upper part of which communicates with the atmosphere lirom the Well d the liquid fuel flows into the annular space between the nozzle tube a and y the lower part of' the conduit g. The conduit g leads into the main air conduit k, and preferably into the Venturi portion thereof., beyond which is shown the.y usual throttle Small holes r are formed in the conduit g slightly above the level of the nozzle a as shown in lig, or approximately level with the nozzle a, as shown in F I to supply air to the mingled liquid fuel between the top of the nozzle a and the level oi' these air holes, Of course it will be understood that some air will pass clown through the well d and with the liquid fuel passing therefrom into the annular space around tube a, as isV Well known in the operation of my patent type of carbureter. y

ln the operation of the apparatus the position of the throttle z' controls the amount of mixture drawn to the engine unclcr the enginesuction. Thetwo streams, one issu- Iling from the nozzle a and subject to* the suction of the motor through conduit g, and

compensating e'ect as in my previous patent, and the additional advantage that preheating is not as important on account of the mechanical emulsifying previous to entrance into the main mixing chamber, which 1l@ This system gives approximately the same may be placed adjacent to the engine Where the mixture will receive some heat. s

'lin Fig. 2 I Show a form Similar to that of Fig. l, except'that the conduit g enters the venturi at an angle instead of axially, as
