\ UNITED STATES HENRY WARD, OF KEARNEY, NEBRASKA.

CARIBURETOR.

Application filed April 20, 1923. Serial No. 638,554.

In carrying out the present invention, it is my purpose to provide a carburetor, specifically adapted to be employed in conjunction with gasoline engines,which will effectively overcome the necessity of e-1n ploying complicated and expensive carburetors, which frequently become out of order, and require numerous adjustments.

A further purpose of the invention is to provide a carburetor, that is extremely simple of construction, and inexpensive of manufacture, such as to permit of its ready attachment to practically all types of gasoline engines.

The nature and advantages of the inventionw'ill be better understood when the following detailed description is read in connection with the accompanying drawings,

the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar wherein Figure 1. is a side elevation, partly in cross section of my improved carburetor, the same being shown as attached to a gasoline engine.

buretor, per se.

Figure 3 is an enlarged detail cross section, taken upon the line 3-3 of Figure 1, and t Figure 4 is an elevation, partly in cross section of the upper end of an air inlet pipe, employed in conjunction with this in-.

ventlon. Referring to the drawings, and particularly to Fi re 1, 5 designates the intake manifold o haust pipe, and 7 the instrument board of the motor vehicle carrying said gasoline engine, These elements are not features of my invention, the same-being of. well known types, and are merely. shown for clearly disclosing the relationship of my invention thereto. A t A The invention embodies a gasoline tank 8 formed centrally with -a cylindrical receptacle 9,- the ends of which extend outwardly of the top and bottom walls of said tank 8, the lower end of this receptacle being closed, while the upper end is open and has positioned thereon a dome-shaped cap 10, The

tom wall of said the nature of-the same being" parts in the several views, and

Figure 2 is a top plan view of the carsaid cap .able manner as at 21 to. the intake manithe gasoline engine, 6 the exside Wall of thereceptacle 9 within the gasoline tank 8 and at 'a point adjacent the bottank is provided with openings 11 for permitting the gasoline fromthe tank to enter into said receptacle, the tank 8 being provided with a filler neck 12, whereby said tank may receive its supply of gasoline. Within the receptacle 9 is a vertical ai'r pipe 13, the'same extending outwardly of the receptacle through an openin in said cap 10, and being provided at its upper end with a cover 14 of fine wire mesh. As 0 shown in Figure 4, this wire cover is carried by an internally threaded ring 15, that engages screw threads upon the upper end of said pipe. The lower end of the pipe 13 is formed with a plate or disk 16, that is in tight engagement with the interior of said receptacle, the pipe being preferably .disposed within the receptacle, in such a manner as to position said plate or disk 16 at a point slightly above the bottom of said receptacle. The disk 16 is provided with a desirable number of openings 17 for permitting the air from the pipe 13 to pass upwardly within the receptacle. 7

Within the receptacle 9 and above the gasoline level is a screen 18, while within 10 are other screens 19, the purpose 85 of the same being to prevent the passage of dirt or other foreign matter, it being of course understood that these screens are formed with openings for permitting of the passage of the pipe 13 therethrough.

Positioned within an opening in the top Wall of the. cap 10 is one end of a fuel mixture conveying pipe 20, this pipe extending'forwardly and being secured in any suitfold 5.

Positioned over the exhaust pipe 6" is a heating drum 22, through which extends the pipe. 20, whereby the fuel mixture passing through this pipe is thoroughly vaporized.

Forwardly of the heating drum 22, and 4 at a point preferably adjacent the intake manifold 5, the pipe 20 is provided with a strainer 23, as wellas a this valve to be operated in a well-known manner. The pipe 20 is also provided with an air intake 25, that includes a suitable form of valve to be operated by the driver 1. the ehicle,- thr gh he medium of a 110 butterfly valve 24,

.rod 26, that extends thrdugh an opening in into the manifold, the same havlng been previously thoroughly vaporized by the heating drum 22, and even though I have herein set forth the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

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

In combinationfa fuel containing tank 2 adapted for horizontal disposition, a ver- 1,1ss4,41a

tica-l carbureting receptacle at the center of said tank, the said receptacle having its top and bottom portions extending above and below the tank respectively, the Wall of said receptaclebeing provided at substantially diametrically opposite points with openings disposedon a plane near the bottom ofsaid tank, an air pipe depending into said receptacle and provided at its bottom with an apertured disk spaced above the bottom of the receptacle, a screened closure for the top of said pipe, said receptacle being open at its top, a removable closure for the receptacle, conical straining screens carried by said closure, and an additional screen arranged in said receptacle at a point above the normal fluid level.

In testimony whereof I aflix my signature.

' HENRY WARD.
