an outer case 2 having an interior cylindrical tube 3 extending from the bottom 4 to substantially the top of the outer casing, whereby an annular chamber 5 is formed about the 6o cylindrical body 3 which is adaptedto serve kas a reservoir for the reception ofthe 1gasolene such asis used in the machine. will use the word gasolene in the description of this invention, althoughit is understood that 65 liquids of similar character may also be used 'in the present device. The interior of this cylindrical body 3 is the chamber in which the air is adapted to unite with the liquid as it sprays from the needle valve, thus "7o forming a roper mixture which'I passes upwardly an yinto the motor for use.

he cross piece 6 is provided at the bottom of the carbureter, which crosses the center of the opening at the end ofthe cylinder 3 and is 75 provided with a de ending stem 7 having a central 'bore 8 in W 'ch is provided a needle valve 9. The nozzle 10 of this valveprojects vupwardly into the cy der 3 and has suitable openings. on the end for spraying thev li uid 8o into the chamber. The valve is adapte to be operated by the spindle 11 which projects downwardly beyond the neck 7 and which is screw-threaded in the latter at the point 12. The handle 13 is provided on the end of the 85 spindle, anda suitable packed connection 14 holds the s indle properly in connection with the nec 7.

By turning the handle 13 the valve is caused to raise and` lower, so that the conical 9o end 15 rises and falls at a point near the shoulders 16 of the. nozzle, for the purpose of .1s a plan view of the same.

'The arm 23 is a which enters the nozzle through the passage 17 which latter opens into the chamber or l9 5 reservoir 5. H The chamber 5 is supplied withasolene pipe running om the source of supply and connected to the plug 1 8 at the lower end of the chamber 5. The rocsup ly received through thisA plug is adaplted to e governed by a check-valve whic vis .constructed as follows: A vertical chamber 19 (see Fig. 4) which is offset from the side of the reservoir, is provided with a ,block 20 105 which is raised and lowered therein by means of la screw 2-1 which latterisaccessible from the top of the chamber. To this block is pivoted: at the point V22 an arm 23 which is also pivoted'at` the point 24 toy the plunger 11o dapted to carry afloa-ter seen that it is provided with 26which is cylindrical and which lies loosely pivoting point sliqud in the tering through ger 25 by` reason -ll4 the space in the chamber 5. vWhen the chamber 5 starts to rise by enthe plug 18, at a certain poili't floater 26 to rise, then the plunof the fixed -pivot 22 will be caused to rise with the arm 23 when the end 27 of the plunger will be seated on the ends 28 or'y the plu admission of t e liquid.

Broadily considered, this va ve consists of a resilient coil which governs the entry of air into' themixing chamber, and, whene suction caused by" the increase of spee will cause the coilto elonparts of the same and enterthe er without passing directl valve `when entering the clyiamber.` `This is for lthe purpose of preventing too muchsucmixing charm speed of for. the purpose of convene iencejI rwill call the abnormal l The forni` of valve pose, and whic'hIprefer, is shown in Fig.` 8 spring 29 which is Woundspirally and conically so as to form a conical shape having a cylin Fig 3, the normal lthe mixing chamber enters underiieat 18, thus cutting o f further! anld yis constructed as follows:

When the valve is inuse as is shown in supply ci air comi into this resilient val`ve, passes up through the c lindrical end 30 and then passes the 'end o the nozzle of the needle valve, causi vthe liquid which comesy out oi' the latter to e sprayed l and passy upwardly in the nature ol a gas mixture into the engine. When'the engine: reaches'the abriormaspeed I have descri ed, the suction in this chamber will become so. great that the resilient valve willbe drawn upwardl thereby, and b d by theinterior cylinder 31 which secures Ythesaine against the various turns of the coil will separate causing a space which will 'admitthe excess of point-asl to haveflittle, if any,`

As the cylindrical end 30 ofthe valve is constructedthere will 'be very little, and possibly no, separationrof the coils when the valve starts to rise, sothatth increased sucg tion affecting the nozzle will only besuch as f enters throu hthe vcylindrical` artt.

When this lever 39 is 'operated for the running of the engine, the same is brought to the position shown in Figs. l 8c 3, when the screw 46 Acontacts with the spring 48 and the valve 42 is then almost closed, so that just sufficient of the gas mixture passes u wardly to merelyl keep the engine going.

en it is desired to entirely shut off the supply of the mixture it will be necessary to further move the lever 39 against the resistance of. the spring 48 until it contacts with the stop 45, when the valve 42 will entirely close the cylinder 37. The movement of the lever 39 in a reverse direction will be governed by the arm 43 which will contact in the extreme movement of the stop 45. It is obvious that the purpose of this arrangement is to have -the lever almost close the valve when it will vcontact with. the sprin ,'and to entirely cut off the supply it Woul be necessary to' hirther operate the lever against the action of the spring.

A drain cock 49 is rovided at the bottom of the reservoir for t e purpose of draining the latter.

Modifications may be made in the resilient.. air governing valve, and 4to a certain extent in its location, without departing'from the broad spirit of my invention, as I believe myself to be the first to produce a valve of this character for this purpose, and without departing from the spirit of my invention as recited in the annexed claims.

Having described my invention, what I claim is: l

1. A carbureter comprising a mixing cham'- ber having a means for admitting li uid therein, and a valve effecting the entry o air into 'said chamber, said valvecom rising resilient separating parts through w 'ch air is adapted to pass whenA the said parts separate,
