To all whom it may concern:

Be it known that I, LEONARD SLIGER, a and a resident of Indianapolis, 1n the county of Marion and State of Indiana, have invented a new and useful Carbureter, of which the following is a full, clear, and exact description.

My invention relates to carbureters, and more particularly to carbureters embodying atomizers and employed in connection withinternal combustion engmes. 7

Among the particular objects sought to be accomplished by my improved carbureter are the following :I. To more thoroughly atomize the hydrocarbon liquid; II. To maintain the hydro-carbon spray as near as practicable centrally in relation to the atomizing chamber through which it is forced to {the engine throttle; III. To heat the atomizing chamber by aid of waste gases from the engine; IV. To adapt the carbureter for use in connection with a variable inlet or damper; V. To enable most of the essential parts to be removed and replaced when worn out; VI. To provide a new and needle valve in atomizing; and V11. To

provide an adjustable float so positioned. .within the apparatus as to afford peculiar advantages.

Reference is to be had to the accompanying drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which- Figure -1 is a section on the line 1-1 of Fig. 2 looking in the direction of the arrow, and showing the improved throttle and atomizing chamber; Fig. 2 is a section on the line 22 of Fig. 1, looking in the direction of the arrow; Fig. 3 is a plan view of the carbureter complete; Fig. 4 is a detail showing, in section, the throttle; and Fig. 5 is a detail showing the form of the inlet valve.

tom, is provided with an annular bead 14:, and fitted into the hydro-carbon chamber at this point is a screw plug 15. A needle 16 is. provided with a threaded portion 17 whlch extends through the screw plug 15, the latter being threadedinternally for this purpose. A toothed Wheel 17 is mounted rigidly upon the needle 16, and is employed forturning the same. A packing gland 16 is fitted upon the threaded portion of the needle 16 and is used to prevent leak from chamber 7. A thumb piece 18 is mounted rigidly upon the needle 16 and is employed for turning the latter-by hand. A lever 19 is pivoted upon the needle 16 as a center, and is provided with a spring plunger 20 for engaging the surface of the toothed wheel 17. The spring plunger 20 is normally actuated by a spring 21 but may be moved by handfor the purpose of bringing it into'and out of wheel.

engagement with this The hydro-carbon chamber 7, at its hot:

A nozzle 22 is threaded externally and is provided'with an end portion 23'. The nozzle 22 is also provided with a flange --24 for rendering it fluid-tight relatively to the atomizing chamber 9. The heating chamber 6 'is slightly convexed, as indicated in Figs. 1 and. 2. This cover is provided with a nipple 26 which is connected with the engine, and is further'provided with a nipple 27 to be connected with the exhaust of the engine. The gases of combustion and hot air from the engine escape through the nipple 26' into the heating chamber 6, and thence out through the nipp16 27 to the exhaust; I-n doing'this, the gases and hot air very effectively heat the atomizing chamber 9.

' A artition 6 separates the hydro-carbon cham er 7 from the heating chamber 6, and the atomizing chamber 9 is integral with this partition, as will be understood from rtion 28 having" generally the form of a ome, and mounted within this portion is a ball float 29. A rod'30 extends downwardly from this float and is connected with a valve lever 31. This lever is also connected with a valve stem 32 which operates a valve 33.

By operating the hand lever 34, the valve 33 is opened and-closed so as to control the supply of liquid hydro-carbon from the receptacle 8 into the chamber 7. A valve sleeve 36- is threaded externally, and adjustably mounted'within one end of the atomizing chamber 9, the latter being threaded internally for this purpose. A valve seat 37 'having'generally an annular form is adjustably mounted within the valve sleeve 36. For this purpose the valve sleeve is threaded internally and the valve seat 37 is threaded externally. The valve sleeve 36 is further provided with lugs 38 extending inwardly and slightly hooked, as will be understood from Fig.- 1. Engaging these hooks is a spiral spring 39. A valve member having generally the form of a fun ml, is shaped so as .to mate the adj acent sub face of the valve seat 37. The valve member 40 is provided with an extending portion 41, the axis of which is substantially 1n alinementwith the end portion 23 of the against its seat. I

The throttle casing 11 is provided with a narrow passage 42 and disposed within the latter are two blades 43, 44 provided respectively with curved edges 45, 46. These curved edges normally cross each other, as indicated in Fig. 4, so that the space he- I tween these edges may be varied by shifting blades 43,- 44

the relative positions of the blades; The are slidably mounted within the passage 42, the blade 43 being carried -upon a stem 47 and the blade 44 being mounted upon a stem 48. A lever 49 is mounted upon a pivot 50. and is pivotally connected to the stems 47, 48, as will be understood from Fig. 4, so that when the lever49 is shifted slightly in a cdunterclockwise direction, according to'this figure, the opening between the edges 45, 46 is re-- duced, whereas a slight movement of the is:

ver49 in a clockwise direction causes the. '1- openmg to become enlarged. ,Pivotally connected with." the lever 49 is a pitman 51, the.

latter being connectedatitslower end to a bell crank lever52l This bell cranklever mounted upon a bracket 53, and

a slot '55. The lever 19 (see Fig. l) carries a small roller 56 which extends through the slot 55. The lever 49 is provided at its outer or free end with an eye 57 by aid whereof it may be connected with an appropriate part controllable by the governor. The supply of hydro-carbon within the hydro-carbon chamber 7 is shown at 58 (see Figs. 1

and 2) iand the spray due to atomizing is shown $159 in Fig. 1.

The operation of my device is as follows: The parts being arranged as above described, the plunger 20 is disengaged from the wheel 17 and by aid of the thumb piece 18 the needle 16- is turned until it is so adjusted relatively to the nozzle 26 as to enable this nozzle to discharge into the atomizing chamber 9 a suitable quantity of the hydro-carbon 58. The engine being now started up, a partial vacuum is created in the pipe 12, and as a consequence, air ,is drawn in through the air inlet 10. This air is, by virtueof the shape of the valve member 40,

concentrated in the form of a stream flowing centrally through the atomizing chamher 9, the portion 23 ofthc nozzle 22 extending to the approximate center of'this stream. The hydro-carbon is thus atomized, being broken up into an exceedingly fine spray and thoroughly mixed with the incoming air. If, for any reason, the en gine happens to produce an undue suction in the atomizing chamber 9-, the valve member 40 is dislodged slightly and the spring 39 compressed accordin ly, so that the valve member 40 moves slig tly to the left, according'to Fig. 1. The valve member 40 bein thus disengaged from the annular seat 37, t e air rushes around the outside of the valve member 40, as well as throu h its center. The air supply is thus great y increased. A

In order to increase or diminish the quantity of the hydro-carbon liquid thus being atomized, the wheel 17 is turned by hand so as to displace the point of the needle 16 to a'greater or lesser extent relatively to the inside of the portion 23 .of the nozzle 22. Whenever the lever 49 (see Fig. 4) is turned in a counter-clockwise direction, that is, whenever the eye 57 is depressed, the blades 43, 44 of the throttle are shifted relatively to each other as above described, so as to curtail the opening presented by the throttle. This, however, is not all that occurs inthis connection; The pitman 51 being depressed, the bell crank lever 52 is rocked slightly in a. counter-clockwise direction according to Fig. 4, the result being that the lever '19. is'turned slightly in relatign to the general position of the hydrocarbon chamber 7, and'in being thus turned, causes a partial turning of the needle 16. The partial rotation of this needle, by virtue of the blades 17, causes the needle to partially close the opening of the nozzle 23 and thus curtail the quantity of hydro-carbon being formed into the spray 59. The reduction in the quantity of hydro-carbon being atomized, and the reduction in the quantity of carbureted air being drawn through the throttle, take place at the same time; hence, the reduction in the volume of combustible mixture supplied to the engine tends to maintain at all times a degree of richness Which is substantially constant; that is to say, when air is passing freely through the atomizing chamber, the hydro-carbon liquid is also being supplied in the atomizing chamber, and when the air supply is re stricted the hydro-carbon supply is likewise restricted. In case, however, of an excessive vacuum being formed in the atomizing chamber, the supply of air is increased slightly owing to the dislodgment of the valve member 40, as above described, the net result being that While the quantity of a1r passing through is greater than usual.

the air is slightly poorer in hydro-carbon with which it is permeated.

u 2 Having thus described my invention, what.

I claim as new and desire to secure by Letters Patent is 1.
