Patented Nov. 27, 1906.

Application filed August 23,1906. Serial No. 275,475.

' sey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Carbureters,of which the following is a specification.

This invention embodies improvements in carbureters of the type particularly designed. for use on explosive-engines, but applicable in various other ways, the invention residing particularly in the special means employed for controlling the admission of air and hydrocarbon to thecarburetor, and the detail features of construction and advan-' tages thereof will be pointed out more clearly as the description proceeds.

F or a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which Figure 1 is a vertical sectional View of a carburetor, showing the practical embodiment of the invention. plan view showing more clearly the mounting of the air-valve and its operative connection with the hydrocarbon-valve. Fig. 3 is a ers ective view of the air-valve, the va vep ate adjacent thereto, and the segment by which the air-valve is operatively connected with the hydrocarbon-valve.

Corresponding and like parts are referred to in the followin description and indicated.

in all the views 0 the drawings by the same and this lever 18 is connected by a rod or the \like with a suitable operating-lever arreference characters.

The general construction of the carbureter does not form a part of this invention and will therefore not be minutely described.

The customary mixing-chamber casing 1 is utilized and is surrounded, preferably, by a jacket or shell, through which a heating medium may pass, a hydrocarbon passage or inlet 3, leading into the casin 1 and an air p'assage or inlet 4 being provi ed at the bottom of said casing in the construction illustrated. Arranged in the mixing-chamber is a suitable mixer A, which preferably comprises a rotatable cage carried by shaft B, said cage or mixer A being operated by any suitable means to facilitate commingling of the elements of the gaseous mixture in a manner which will be readily ap arent./ The hydrocarbon-inlet 3 leads to a ushing 5, externally threaded, as shown at 6, so as to be screwed Fig. 2 is a bottom into an internally-threaded hollow boss 7,

' forming the center of a spider8 in the casing 1. The bushing 5 has a stem 9 mounted therein, and the upper end of this stem 9 is reduced to a point to form the valve 10, which is adapted to close and open an opening 11 in the bushing, which forms a continuation of the hydrocarbon-inlet 3. A stuffingboX 12 is located in the lower portion of the bushing 5, and the stem 9 passes therethrough, said stufling-box preventing passage of the hydrocarbon, other than through the inlet-opening 11, which leads to the mixingchamber of the casing 1.

The means in the casing 1 and utilized for securing a thorough admixture or commingling of the air and hydrocarbon may be of any suitable type conducive to obtaining the best results, said means not being described for this reason. 7,

The air-inlet 4 in the casing 1 is normally closed by means of a va ve-plate 13,provided with a plurality of inlet-openings 14, said valve-plate being secured to the casing 1 in any substantial way.

An air-valve is indicated at 15 and comprises a disk-like body in close contact with the plate 13 and adapted to close and open the openings 14 thereof in an evident manner. The plate 13 is formed with an apertured lug 16 at its peripheral portion, and a pivot 17 pivotally connects the valve 15 with the plate 13, the pivot passing through the opening in the lug 16. The-valve 15 is adapted to therefro adjacent to its pivota support,

ranged adjacent the seat of the vehicle on whichthe invention is being used.

The valve 15 is formed with an arcuate slot 15 in the body portion thereof, which slot as the valve is actuated will register with the ports in the valve-plate 13, and thereby open said ports. The arcuate formation'of the slot 15 is necessary, as the same not only coacts with the ports of the plate 13, but permits free movement of the valve 15, though the stem of the hydrocarbon-valve 9 projects below said valve 15.

The valve 15 is connected with the valve 10 for operation of the latter. The stem 9'of the valve, 10 is threaded at its lower portion, as shown at 19, the threaded portion .19 being IIO screwed into an opening 20 in the central portion of the plate 13. The stem 9 is thus adjustvalve 1.5,and: adapted td hold, the segment-- plate-man ad 'ustable-po'sitiom The arm or lever 18 may be limited, in its.- movement to openthe valveto the maximum by means of an adjustable stop 25or the like Theoperetion and, advantages oi the invention are as follows: Asthe armor lever 18 I is actuated, to open the valve-15 the Segment plate 22;, carried bythe valve. is moved therewith, and as this plate is connected with the pinion on the stem 9 the stem 9 will be simultaneously rotated on movement of the sir-valve 15, thereby actuating the hydrocarbonwalve 10. The moving of thelever 18 will thus simultaneously open or close the air and hydrocarbon inlets of the carbureter, and as the. hydrocarboirvalve 10 is connected with the valve L5, as hereinbetore described, the proportionate inoveu'ient of the two valves may be regulated definitely to secure a proportionate desired admixture of the hydrocarbon and air admittei'l to the carbureter. Further, the valve 1.5. constitutes a throttle for the engine, and it is adapted to ectuate the valve 10- and cut oil the. supply of hydrocarbon and air in a manner which will be obvious. The provision oil the adjustable plate 22 admits of variation, in the proportion of air and hydrocarbon mixed by adjnstment of saidplate as to. its connection with the valve 10-;but such adjustment having once been secured the desired proportion of the ingredients mixed will be absolutely maintained; in the operationot the carboreter, allowing the production. of a homogeneousmixtu-re ot fixedly correct proportions, which insures perfect combustion, at all points of the tlrtottle, remoring the liability of the spark-points to become carbonized from burning hydrocarbon andelimiristingthe smoke and smell f om this sourcqreduca s the amoun oi hydrocarbon. n cessary ssexvse for the production of'a given horse-power to a minimum not secured heretofore and permitting the operation of engines of the explosive type by a single lever or member under extreme variations of speed and power.

Having thus described the invention, what is claimed as new is 1,. A carbureter comprising a mixing-chamber, air and hydrocarbon valves therefor, a

a pinion applied; to the stem of thehydrocar- I hon-valve, a segment pivoted it one end to: and coaxiall v with the pivot of the airvalve and having teeth in mesh with those of the pinion aforesaidend a. fastening arranged intermediate of the ends of the segment aforesaid to admit of adjustment of the position of the segment in the manner specified.
