To all whom it may concern."

Be it known that l, CHARLES R. GREUTER, a citizen of the United States, residing at Saugus, in the county of Essex and State of Massachusetts, have invented certain new and usefuL Improvements in Carbureters, of which the following is a'specification, such as will enable those skilled in the art to which it appertains to make and. use the same.

This invention relates to carbureters for use 'in'connection with explosive engines using liquid fuel and the object thereof is to provide a carbureter of this class which will he e simple construction, eflicient in opera'- tion, and particularly to provide means whereby the carbureter may be attached to either the right or the left side of the engine and will project either forward or to the rear of the manifold to which it is attached, in order that it may be attached to all types and designs of engines without any special fittings, which is impossible with most carbureters as now constructed, because of interference by the steering mechanism, magneto, generator, or other mechanism connected to or adjacent to the engine. These and the other objects of my invention will more fully appear in the following specifica tion, of which the accompanying drawings form a part.

Certain parts of the structure illustrated in the accompanying drawings and more or less fully described in the specification form the subject matter of my companion appli- 1915, for carbureters, and accordingly are not claimed herein.

Figure 1 is a sectional elevation of my carbureter assembled for attachment to the ri ht-hand side of a motor, with the body the carbureter projecting forward from the manifold. Fig. 2 is an elevation, partly in section, of the neck and hood, and the upper portion of the body of the carbureter assembled for attachment to the left side of an engine, with the body of the carbureter rojecting forward from the manifold. Fig. 3 is a lan view of my carbureter assembled as s own in Fig. 2. Fig. 4 isa view similar to Fig. 2, showing the carbureter assembled for attachment to the right side of an engine, with the body of the carbureter projecting forward from the manifold. Fig. 5 is a plan view of the carbureter ascasing 1, which forms the body of the carbureter. The body is of considerably greater length than width, and is provided with air intake openings 2 and 3, either of which is of sufficient capacity to supply the requisite amount of air without creating an undue vacuum, and with venturis 4 and 5 arranged longitudinally on either side of the center line X-X of the carbureter body. Liquid fuel nozzles 6 and 7 are mounted in the venturis 4 and 5 and each is in communication With the chamber 8, to which fuel is supplied from the float feed chamber 9. In the openings 10 and 11 in the walls of the body 1, are mounted housings 12 and 13, which are secured in position by'fstuds 14 and 15. The housings are interiorly screwthreaded to receive the screw-threaded stems .16 of the tapered needle valves 17 and 18,

which project into the nozzles 6 and 7, and are the means employed for regulating the fuel supply. To the upper end of the stem of the needle valve 17 is secured a rod 19, by means of the universal joint 20, as shown in Fig. '1. Valves 21 and 22 are longitudinally movable on the guide stems 23, and determine the vacuum under which venturis 4 and 5 operate.

My carbureter is alsoprovided with a hood 24, into which the venturis discharge, and the hood is provided with a neck- 25, having a flange 26 adapted to be secured to the flange on the manifold of an engine. In

the neck is mounted a throttle valve 27 on a shaft 28. On the throttle valve shaft 28 a cam 29 is mounted, outside of the neck 25. The cam 29 acts upon the cam roller 30 mounted in the lever 31, which is secured on a shaft 32 by means of the clamp screw 33. The lever 31 may be adjusted in any position on the shaft 32 by means of the clamp screw 33. The lever 34 is permanently secured to the shaft 32 by means of the pin 35. To the lllb end of the lever 34 is pivoted a valve 36, which acts as a throttle to the veinturi 5, when the parts are assembled, as shown in Fig. 1, and when the throttle valve is closed, as shown in Fig. 1, the cam 29 looks the valve 36 in the closed position. When, however, the throttle is partially open the cam 29 ceases .to lock the valve 36 on its seat and when the vacuum in the hood has risen sufiiciently to raise the valve 36 from its seat the venturi 5 and its nozzle 7 are thrown into action. The hood 24 is secured to the body by studs 37, which are so spaced, that the hood may be reversed so that the neck 25 will be forward or to the right of the center line of the body instead of to the left or rear as shown in Fig. 1.

The operation of my invention is as follows:

With the carbureter assembled as shown in Figs. 1, 4 and 5, it is adapted to be attached to the right side of the engine with the body projecting forward from the center of the manifold, avoiding interference with the steering mechanismpr other parts to the rear which might interfere if the carbureter were centrally located with reference to the manifold. When the conditions are such, asis often the case, that the carbureter, assembled as shown in Fig. 1, cannot be mounted because of interference from the magneto, generator or other parts, the screws 37 may be removed and the hood reversed. The clamp screws 38 should then be released and the parts reassembled in the position shown in Fig. 6. .The body of the carbureter when so assembled will project to the rear instead of forward of the center of the manifold. When the carbureter is to be attached to the left side of an engine with the body projecting forward from the center of the manifold, the parts should be assembled as shown in Figs. 2 and 3, and when it is to be attached to the left side of the engine with the body projecting to the rear from the center of the manifold, the parts should be assembled as shown in Fig.7.

It will be noted from an examination of the figures that the cam 29- on the shaft of the throttle valve 27 and the lever 31 may be mounted on either end of their respective shafts as the exigencies of the case may require, and that these parts are so designed that they may properly coact in either position.

Having described my invention what I claim as new and-desire to secure by Letters Patent is:

1 A carbureter comprising a body having a plurality of venturis; fuel nozzles arranged to discharge into said venturis; needle valves for controlling said nozzles; a hood applied to the carbureter body and constituting a chamber over the outlet ends of the two venturis; and a valve carried by valves froma fixed control station;

said head and adapted to control the outlet end of one of said venturis, said hood being reversible with reference to the body so as to bring its discharge opening to one or the other side of the center, and to place its throttle valve over one or the other of the Venturi outlets at will.

2. A carbureter comprising in combination a body having two air passages; valves in said body for controlling the supply of carbureting liquid to said passages; connections for operating a definite one of said valvesfrom a fixed control station; a supporting and connecting hood for said body having a tubular neck communicating with both said air passages and adapted for attachment to an engine intake in different angular positions; means for connecting said body to said hood in two relatively,reverse positions; and a valve for controlling one of said air passages and adapted to be mountedin said hood in two relatively reverse positions corresponding to the two positions of said body.
