designed toibe at alevel suitable4 for supplylng` the ycarbureter iby gravity with liquid fuel. 5` is an auxiliary chamber apparte* nant to the supplemental liquid receptacle,

4, positioned for receiving the liquid by gravity from said supplemental liquid receptacle, 4, through they discharge tube, 6,

having itsdischarge mouth at a slight inclinatlon. sothat it is adapted to be closednormally by the check valve, 7, which is opened'by gravity` `iow of liquid from the receptacle, f1, into said auxiliary chamber, 5.

The fitting, 2, is'rhost` conveniently made as acasting` adapted to be inserted through -a circular openingin the upper convex side offtlie reservoir, 1, which has a flange, 2, fitted to the curvature of said reservoir 'so as toy be riveted down tightly thereupon through` which the lower end portion of said' fitting protrudes a short distance into the reservoir. "In the upper part of this fitting, there is lcontained the valved cham-` ber,3, the bottom of which `is preferably for certain specifcpurposes hereinafter explainedl locatedat or a little above the level of` thehighestpoint of the curved upper side of thereservoir 1. Thisvalved chamber, 3, is closed by a topfplate, 8, making it air-tight except as to the connections and communications` hereinafter described. A liquid fuel. feed pipe, 9, extends from` the lower part ofthe interior ofthe reservoir, `1,.for discharge` in tothe upper partV of the supplemental receptacle, 4. As a matter of convenience inv'constructing and assembling this pipe extends down through one 'side wallof` the'fitting, 2, which has ,a vertical passage,.2", in reality forming fa portion of the pipe, the :lower end portlon being screwed into thelower end of saidvertical i passage, and 4the Vupper portion being 4,screwed'into'the upper end thereof.

From the bottom of the chamber, 3, u liquid discharge nipple, 16, is provided extending down into the cavity of the reservoir, 1, having its lower end vslightly deflected so 'es to present its mouth at a slight inclination so that it is normally -olosed by grevity by the liep valve, 17, which is opened by gravity flow of the liquid from the valved chamber, 3, back to the reservoir, l..

In Fig'. l there is shown :L modified construction of the menus for carrying andi? opm'eting the nir inlet vulve, consisting in tlnlttlie'zuen of the uirl inlet port :11nd of the volvo covering it designed to be sul'lloient to enlise the suction operating upon the vulve when once Seated to hold it on vits sent firmly enough to require the re- A` stituting a fioat for the receiver, 22, which fao ` thechamber, 3, into the reservoir 1 is de- 4 through" said4 pipe, 14;' 4but it may still be scribed. In the construction shovvnin Fig.

4 the valve maybe connected with the operating` lever, Without any appreciable or considerable range ofrplay,` the valve and lever moving substantially together. v In this construction the action of the v'alvein A -fseatingis gradual until it comes near toits seat when the suction will pull it suddenly on to its seat with the same effect substantial-ly as produced'by the spring action on i p the other form.

I n Fig. 5 there is shown a modification in a different'respectwhicli can be employed with either form of valve laction above described. The modification consists in suboat is causedto move the alii.` valve, 11, for

" unseating-it when the liquid accumulates in the chamber, 3, -to a sufficient height to lift the float and cause it to operate the valve. In this construction it will be understood that the lever action on the valve is reversed, that is to say, theyfioat is connected v to the lever, 35. on theA same arm ofthe le? 4 negtions for shifting the' lever past the cenve1 which engages the valve stem 11a for operating the valve 11. The spring con ter are substantially the same as in the otherfconstriietion. VV'hen this method is employed, the discharge of the liquid from sirably reduced'soas to be enough less than the cross-sectional area yof th'e aperture of theipipe, 14, to permit the chamber, 3, to

fill promptly when the overfiow commences large 'enough to permit the chamber, 3, to empty andv cause reversal of the valve very promptly so that the relilling action -inay reale, 4',

beginUas soon as the supplemental recepcan empty into the auxiliary charnblel'rs. g l i' l When employing the construction des scrgihed';V consisting -of the fitting, 2, mounted upon the main reservoir, 1, it is convenient t to associate with this fitting means for indicating the level `of liquid in the reservoir,

V, thusdispensing with the necessity of a separate. fitting for 'that purpose." To accomplish. this the fitting, 2, mayhave an arm, 2,eiitending down into lthe reservoir,

1', wheiithe fitting is mounted thereon, 'and' on' which there is pivotedfa fioat army-10,

'carryin a small float, 41, at its free" movement of said fioatd arm as the'oat rises i and4 falls with the level of-the liquid, to rock the shaft, 45, for operating'the index pointer, 44.
