Original application tiled July 16,V 1910,

To all whom #may concern.'

Be it known that I, lVILLIAnrJ. Rnnnsxv, of Minneapolis, Hennepin county, Minne- Vsota,'have invented certain new and useful Improvements in Carbureters, of which the following is a specification. t

My invention relates to the type of carbureter shown and described in my pending application iled October 11, 1909, SerialNo. 522,200, and the primary object of my presont invention is to 'provide an improved arrangement of the oil bearing v-.f'icks and the manner of feeding the oil and-air thereto.

A further object is to provide a free and specification of Letters jlatent.

positive oil feed that is easily adjusted to suit 'varying conditions of the weather and will be thoroughly economical in the use of fuel. A further object is to provide means for thoroughly saturating the air and eiiecting an equal distribution of the fuel.

A further object is to provide a carlbureter capable of handling or vaporizing a low grade of oil and producing a mixture that will be highly explosive and easily ignited.

A 'further object is to provide a carbureter Whiclrvvill insure a smoother and more uniform workingF of the engine, particularly those of the multi-cylinder type. l am also able to effect a very complete coinbustion, thereby insuring a minimum amount of carbon deposits, reducing the 4necessity for repairs and giving a longer life to the engine.

My invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming 4 part of this speciiication, Figure 1 is a vertical sectional view of a carburetor embodying my invention, Fig.2 is a horizontal sectional view, Fig. 3 is a detail sectional view illustrating the arrangement of the governor device, Figs. 4 and 5 are detail sectional 'views of the wick carrier, showing modified. constructions, Fig. G is a detail view of the eccentric deviceby means of which the reservoir float is controlled.

The principle involved in the operation of this carbureter of causing the currents of air to come in contact With the oil saturated wick or other sui-table conveying means, is similar to the one set forth in my prior ap- CARBURETIER.

vided with a series of openings of different horizontal levels to adapt the wicks for gathering up the oil and being exposed to the air currents at different points. Air is admitted to the oil chamber and permitted to flow into the ports or openings in the wick carrier and coininunicatevvith the oil carrying wicks.

lin the drawing, 2 represents a casing having an air intake passage 3 and a valve 4. 5 is a stein supported at each end in the walls of said casing and carrying an eX- lternallythreaded sleeve 6 below Which a valve 7 and coil spring 8 are arranged. The tension of this spring is regulated by the adjustment of the sleeve 6. rlhe valve 7, preferably of cork or other light material, is tapered inform and has a Seaton the upper beveled portion 9 of a wick carrier 10 which is preferably cylindrical'in form and has a series of longitudinal sockets 11 therein adapted to receive the wicks 12. These wicks preferably consist of wire coils having cores -of ordinarywicking. The Wires inclose the cores and allow the oil to penetrate ltherein and the oil also collects on the surfaces of the Wires and creeps upwardly thereon to a position where it will be in the path of the air currents. The Wicks are substantially the same as those described in my former application, above referred to, apd thei.r lower ends preferably depend below thc wick carrier into a reservoir lei that is adapted to contain a supply of oil and a float 15. To prevent the inner surface `of the float' above the oil level from covering up the air inlet ports, the wick carrier is provided with a series of annular grooves 16 in. its outer surface, in the bottom of which holes 17 are provided aty intervals leading to the sockets 11, wherein the wicks are .'ai'ranged. Some of these holes may be below the level of the liquidin the reservoir l-l and some of them may be above the level of the liquid, thus permitting currents of air to mingle lwith the oil as it rises 0n the wicks and passes to the mixing chamber.

The upper ends of the wick sockets have ports 1S extending through the valve seat 9 and are normally closed by the tapered valve 7 resting on said seat. An air intake 19 having ports 20 is provided, communicati ing with the reservoir 14 and by this means -a certain predetermined volume of air can be admitted to the reservoir to mingle with the oil. The mixture of air and oil passes through the ports 18 when the valve is raised and mingles with the air currents brought in through the pipe 3 in the mixing chamber 21, the valve 22 separating this chamber from the passage which leads tothe engine cylinder. This mixing chamber forming the upper portion of the carbureter is readily removable from the wick carrier vby means of the joint 2% and when: the mixing chamber is detached the wick carrier Will be exposed and may be also removed forinspection or repairs. An annular chamber 24 is provided, extending around the carbureting passage and having Walls provided with intake and outlet openings through which hot 4air or hot water may be admitted to keep the walls of the earbureter at a suitable temperature to obtain the best results.

. A bail 25 rests on the float and a lever 26 is" connected to said bail and is pivotally mounted at a point intermediate to its ends onl a pin 27, which is"'eccentrieally formed on the hub 28. The hub 28 has an operating lever 30 and a loop 31 has its inwardly turned ends varranged to bear on the outer end of the hub 28 and on a plug 29, that fits within a socket in the casing 2 opposite and in line with the hub 28. The end of the lever 26 fits into a recess 32 in the stem 33 of a valve 34, which is adapted to close a port 35 and shut off the flow of the liquid fuel therethrough into the reservoir. The upper end of the valve stem is guided in a socket 36. rlhe position of the float l5 determines the flow of liquid fuel into the reservoir and by the rotation of the eccentric hub 28 the position of the float is regulated so that it will shut the valve or open it, according to the level of theifloil in the chamber. The higher the float in the reservoir, the larger number of holes leading to the wicks will be covered by the oil supply and a fewer number of holes be left open.

for the passage of the air currents. On the contrary, when the oil and the float are low inthe chamber, a large number of the holes will be exposed to the air currents and the number of those through which the air may pass into contact with the wicks will be correspondingly reduced.

The movement of the lever 30 will allow the proper adjustment of the float according to the volume of feed desired and the degree of richness of the mixture.

In Figs. a and- 5 Iphave shown 1nodifica tions, which consist in providing wick carriers of dierent formation. .In Fig. 4 a carrier,37 is shown, provided with a series of narrow vertical slits or slots 38, leading to the Wicks, and in Fig. 5 a series of tubes creased flow of air or oil through the walls of the carrier into contact with the oil bearing wicks.

In various ways the details .of construction herein may be modified, without departing from my invention.
