In'order'to 'provide' 'mean for ,regulating the fing 1- a-valvefrnernher the fornirci alsle'eve andrtoav'oid insonne instances carrying-tha i pipe around; the-carbureter provide at :the oppositesideo. the lattei'- a similar boss Loc ` The-sleeve is secured in the arm or .handle 39, secured rigidly to the' valve mem-v valve head 41 which cooperates with the valve seat on sleeve by a screw 40; The dna the hydro-carbon inlet and'regulates the flow 4of the latter into the mixing chamber in inlet andoutlet amounts proportionate to thesize of the air passages as the partial rotation of the sleeve, necessary to close orv o en said assages', will cause` it to be moved ongitu ally sli htly by means of its screw thread 36- whic will cause a movement of the valve head 41 relatively to its seat.4 -.To fa-, cilitate the adjustment of the valve head-to regulate the flow of hydro-carbon in' the first instance, I provide the stem, 42, on which it is'mou'nted, with screw threads'43 Yand extend it through a central threaded aperturev in the boss 37 the upper end of which is split forming the ears 44 ,which may be ad'usted relatively to clamp the stemin adjuste posi- 'tion by a bolt 45. The location of the valve seat or hydro-carbon inlet above the air inlet 34 and the foraminous support 26 between them the fluid flowing therein will be evaporated While the air passing. therethrough will be subdivided into numerous small currents which will cause it to become thoroughly 4 mixed with the hydro-carbon gas. "While I have described the device as employin a fluid-hydro-carbon it will be understood t at* it may be usedV equally Well for combining an explosive mixture of gas and .air 'when the former Vis introduced directly in a gaseous. state through theinlet 24. i

A carbureter embodyin my invention is simple in construction .an re uires but few parte, the arrangement of Whic is such that y an adjustment of the air inlet passa e the quantity of hydro-carbon which shoul to the engine Acylinder is tionately.

I claim as my invention:

1 In a carbureter, the combination with a pass regulated propor- I caslng having air 'inlet and 'outlet passages and a hydro-carb on inlet having a valve seat, of an oscillatory member for adjusting the air inlet passage, avalve head carried thereon and coperatmg with the valve seatV and means for causinga longitudinal movement of the member relatively tothe casing during its oscillatory movement to' control the discharge area of thehydro-carbon passage.

2. In a carbnreter, the oombination'with a casing comprising a mixing chamber and a hydro-carbon reservoir located beneath and Y essaies Pug 1 Amovement of the at one side of the chamber and having a pas- Sage leading Int() the JQgervgjr hgggglglg he chamber and a valve seat insaid passage, of ari-arm located'at the betteln voir and chamber, a ioat connected to the one end of the arm, and a. valvehead supported on the latter and coperating with .the seat in the inlet passage. v A

3. In a carbureter, the combination withV a casing comprising a mixing 'chamber and a hydro-carbon reservoir located beneath-'and at one side'oiE the chamber and having an inwardly extending projection arranged beneath the chamber provided with a transversely extending hydrocarbon linlet, a valve seat -in said passage and means at the ends of the passage for attaching a su ply of the reser-.` pivoted to ,the casing beneath the pipe, of an armlocated at the bottom o' the reservoir and pivoted to the casing beneath the' chamber, a float connected tothe one end ofthe arm, and-a valve head supported on the latter and cooperating with the seat in the inlet passage.

4; In a carbureter, the combination With a casing comprising a mixing chamber and a hydro-carbon reservoir located beneath and -at one side of the chamber and having a passage leading. into the reservoir'beneath the chamber and a valve seat in said passage, of an arm at the bottom ofthe reservoir pivoted at one end beneath the chamber, a float conl nected to the otherl end of stem carried on the arm vand cooperating with the inlet passage seat and aremovable at the bottom of the reservoir forming a gui e for the valve stem.

' 5. In a carbureter,'the combination with a casing having air inlet and -outlet passa es and a hydro-carbon inlet, having a -va 've seat, of la rotary longitudinally movable member for adjusting the air passages and a valveyhead carried on saidmember and op-A eratedfby the longitudinal movement thereof the arm, a valve 4 relatively to said valve seat.V

6. In-a carbureterJ the combination With a casing having air inlet and outlet .passa es and a hydrocarbon inlet, having Ia valve seat, of a sleeve threaded the 'casing and reyoluble thereinto-adjust the' air passages, and a valve head on the sleeve coperating vwith said seatV and carried relatively"theretoby the longitudinal movement of the-sleeve.

f .7 Ina oarbureter, the combination with "al casing having air. inlet .and outlet passages and a hydrocarbon inlet extending into the casing and having a valve seatpo a rotary sleeve in the casing, and a valve head adjustable on the sleeve relatively to the valve seat, means for cansinor a relative longitudinal Isleeve during its rotary movement. l i HENRY L.
