' lai-ged portion 45, is provided near the lower `a tubular member 35, the lower end of which which may be regulated til-inning the' sleeve 29, in or out upon the stud 9,6. A series of indentatlons 31, are formed upon the periphery ofthe .sleeve 2li( which are adapted to receive the rounded end of a locking;-` pin 32, extending downwardly from a bore in an arm 38, in which is inserted a spring 34. This construction enables the tension of the valve-closing spring 30, to be adjusted to the utmost nicety.
Extending upwardly into the casing 23, is
is connected -by .means of a pipe 86, Fig. l, with the crank-case 12. Gpenings 37, Fig 3 and 6, are arranged around the part or, for the admission of air. A tapered injector nozzle 38, is tapped into the upper end of the part 35, and extended coaxially into the mixing chamber 22. Located above said mixing-chamber is a bowl 39, having therein a central tube 40, extending upwardly to a level above that oi the top. Said tube, which is provided with openings 41, nenrits base, externally and internally readed'ga't 'its upper end as shown, the 'on screw? ead beingfor the reception offen annilja'r nut- 42., and the other for the recelptionoffe screw-threaded plug 43, which is passed throughJ said nut and into said.. tube. Extending downwardly 'from said plug into the mixing-chamber 2:2, is a tubular member 44, the diameter of the greater portion of which is less than that of the interior of the tube 40, so as to forni an annular space between the two. An enend of said tube which is adapted to form a tight joint with the opening in the casing. Openings 46, are formed in the part 44 in communication with a central bore 47, which leads' to a needle-valveopening 48, adapted to be closed by a needle-valve 49, the enlarged stem 50, of which is provided with a tine screw-thread and is tapped into the plug 43. A hand-wheel 51 having peripheral notches 52, is secured to the part 50. A spring-catch 53, Figs. 1 and 6, is attached to the bowl cover 54 and arranged to cngage with the notches 52 to yieldiugly lock the hand-wheel vin any desired position. This arrangement enables the needle-valve to be adjusted with the closest accuracy. One or more small openings 54, Fig. 3, should be provided in the cover for the admission of atmospheric air. TheI bore 55, of the tube 44, below the needle-valve opening, vis made quite large andis flared outwardly at the lower end as shown at 56 in order to cause the liquid fuel to spread in a thin sheet for the purpose hereinafter stated. Thedischarge end of said tubeis located in immediate proximity to and pref` erably slightly back of the tapered end of! the nozzle 38. l
An annular shaped float .37, of cork or ,sie
58, Figs. 4 and 5, is rigidly attached to said 'float and is pivoted at 59, to a pivot-pin secured in the bowl. A late al offset 60, is formed in the bowl, in the bottoni of which is provided a valveopening 6i, in com 1nunication with a tube 62, leading to a gravit-y or other liquid fuel supply not shown,o tl any well-known form. A needlevalve 6B, adapted to close the valve-opening 61, is provided with a steini4, having a ball 65, near its upper end, fitted in a socket 6G, which, in turn, is attached to one end oi .the lever 58, said ball and'soclet forniingajuni versal rjointl for imparting` the requisite freedom of movement to said valve. As the valve 33, is lifted, by the lowering` of the fuel-level in 'the bowl, oil from the source of supplyispermitted to iiow in until the rising of the float causes the valve to close in the usual' well known way.
Formed upon the carbureter, between the bowl and discharge nozzle, is an upwardly extcndedboss 67, having a vertical bore for the reception ofthe screw-threaded st cni of a needlesvalve 68, adapted to .close a valveopening` 69, leading to the mixing-chamber. i-ihand-wheel having notches 7l, in its periphery, adapted to be engaged by u spring 72, ena A tube 73, l, 4 and 7, leadingto a source of water supply not shown, is in coniinunication with the valve opening 69.'
y The operation of my improved devicel is as follows: Upon the 'up-stroke lof the piston, air drawn into the crank-case, the quantity thereof beingr proportionate to the piston speed and the relative extentto which. the governor-controlled valve 14, is caused to open. Upon the return stroke, thein! Vdrawn air is compressed in the cranle'ase until the port 7, is brought into registration with the luy-pass S, when the coinpresed air rushes through the port 3, into the conn bustiouechaniber, thereby causing a partial vacuum to be formed in the mixing-chainher E22, tends to open the valve 3l, and causent-1110epherivy air to be drawn into the mixingchumber. At the "saine time the partial vacuum in the mixing-chamber causes a downward suction in the tube ,Fuel troni the bowl 39 in which it is maintained at a constant level by the float 57 is drawn through the vopenings 41 into the annular space around the tube 44, in which it stands normally at a like level. The downward suction in the tube causes said oil to rise sufficiently in said annular space to, jdow through the openings 46, and needle-valve 48, into said tube and thence into the inizi ingr-chamber from whence it, with its oo1nplement of air, is transferred in vaporous form to the combustion-charnber' ready to s the valve to be adjusted.
