No. 888,171. I

To 'all' whom it my camera:

" Be it known that I, Monnon D. CoLnA'rn,

a citizen of the United States, residing at the city of Hampderi, county of Penobscot, State of Maine, have invented cert'ain new and useful Improvements in Carbureters, of

which, the following isa specification.

This invention relates to improvements in carbureters. k

The objectsfof this inventlon are: first: to provide an improved carbureter in whichthe vintroduction of the air and the liquid hydrocarbon in ro r roportions is automatically contro le econd: to provide an improved carbureter which is of large capacity Tan-(l, at the same time{ simple and compact in "structure. Third: to provide an improved carbureter in which ractically all of the liquid hydrocarbon is uti ized.

Further objects, and objects relating to structural details, will definitel appear from the detailed descriptionto fol ow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointedjout in the claims.

A structure embod ing the features of my invention i'sv clearly ili ustrated in the accomanying drawing forming a part of this specica'tion, in which:

' 1 Figure 1 is a detail side elevation yiew of a structure embodying the features of my invention, partsbein shown in section to show their structure, an other parts are shown 1n conventional form. Fig. 2 18 a detail vertical sectional view of my improved com viewsv bined air and liquid hydrocarbon feed valve. Fig. 3' is adetail transverse sectional view taken on a line corresponding to line 33 of Fig. 1, showing the arrangement of the s iral partitions b of the auxiliary carbureter chamber B.

In the drawings, similar letters of reference refer to similar-parts throughout the several Referring to the drawin I provide a main carbureter chamber A an an auxiliary carbureter c'hamber B. The main carbureter chamber is 'preferably cylindrical in fiirm,

t is

preferably comparatively small in diameter and of considerable length.

Arranged within the 'main carbureter,

0. These screens are arranged in an inclined position, one above another, so that the upper screens, deliver onto the screen next below, the screens being alternately inclined.

The main carbureter chamber is connected at its lower end to the lower end of .the auxiliary carbureter chamber B, and delivers "thereto. Within the auxiliary carbureter one above another. The cham ers etween these pans are connected by passages 11. The pans B are adapted to contain li uid hydro-carbon, as is illustrated in Fig. 1. he delivery of this liquid hydro-carbon is controlled by suitable valves and floats e, as will be hereinafter pointed out.

The partially carbureted air passing through the auxiliary fromthe main carbureter chamber is caused to take a s iral passage by the s iral partitions 1). ese partitions are re erably made of some thin material provi ed' with a covering of cloth or other suitable material 1), adapted to carry u the liquid "ydro-carbon by capiliarity. The lower edges of the partitions project into the liquid hydro-carbon contained-in the pans, as isillustrated in Fig. 1.

The gas and carbureted air, in passing throu h the auxiliary carbureter chamber, is cause toass through a very long passage, so that it ecomes properly carbureted.

The delivery pipe is connected to the upper end of the auxiliary carbureter chamber.

C is the air tank to which the air may be supplied under pressure by any suitable means, the same not being here illustrated. This air tank is connected to the upper end of the main carbureter chamber A by means of the pipe C and the valve casing F which is mounted upon theup er end of the carbureter chamber, as clear y appears from the drawings. Q

A pressure-regulator C is provided for the air supply pi e. The delivery pipe Lis also supphed wit a ressure regulator, as I. The. air tank an pressure regulators are shown in conventional form.

. provi carbon is fed by gravity. The li uid hydro: carbon is elevated to the fee reservoir through the-pipe d by means of airp'ressure, the storage reservoir being connected to the air tank by means of a pipe c. The .pi e d is provided with a suitable valve d; A oat d is provided for controlling the valve (1, thereby controlling the'le'vel of the liquid hvdro-carbon in the feed reservoir.- The pi e c is also providedvwith a valve, as c, w 'ch may be used, if desired, to control the delivery of the liquid hydro-carbon to the feed reservoir, The liquid hydro-carbon is delivered to the main carbureter chamber by means of the pipe E. which is provided with branches 6, delivers the liquid hydro-carbon to the pans B of the The branch pipes e of the pi e E project 'throu hthe walls of the chain )er B and are (Ted with-suitable valves and floats e which are illustrated in conventional form.

-By. this means the liquid hydro-carbon is he t at a constant level in the pans B.

he delivery of liquid hydro-carbon to the main carbureter chamber is automatically 1 controlled by the delivery of air thereto, and

the delivery of air is, in turn, controlled by the delivery of gas from the carbureter.

The pressure regulators C and J are so set that when the pressure in thc'carbureter chambers falls below a pre-determined point, the air is admitted. The incoming air opens the liquid hydro carbon valve, and admits the liquid hydro-carbon so long as the air continues to enter.

The ports for the air and the liquid hydrocarbon are so proportioned'that the air and liquid hydro-carbon are admitted in proper proportions. The structure by which this is accomplished consists of an exterior casing F which is mounted on the carbureter chamber A and is connected by means of a coupling f to the air pipe 0. Within the casing F is supported a U-shaped casing G, one end of which 7 opens in the casing F and the other into the coupling The casing G is provided with ports 9 through which the air and liquid hydro-carbon is delivered. These ports are controlled by a piston valve H which normallybears against the stop- H which is mounted on the oil delivery tube G. This valve H is chambered to receive the lower end of the liquid hydro-carbon delivery tube G which is provided with ports g. The liquid hydro-carbon delivery tube G is arranged through the coupling f and'is connected to the pipe E.

When the valve H ,isin its normal or I closed position, it not only closes the ports g,

but also the ports 9. its normal position by means of the mercury The valve H is held in M vvhichthe casing G contains, as clearly appears in they drawings. f It is evident, how- A branch pipe 13,

ever, that. a spring might be used for this purpose." The mercury is preferred as the desired pressure upon the valve can be ac curately gaged thereby, and remains conregister therewith. It is evident that by adjusting this cylinder, the size of the delivery ports can be controlled. This adjustment is accomplished by means of sand 9 upon the outer end of which is a suitable nurl 9 With the, parts thus arranged, when the pressure in the carbureter chamber falls below a predetermined point, the pressure'in the air supply pi e opens the valve H, thereby permit-tingt edeliveryof bot-h air and liquid hydrocarbon to the main carbureter. As soon as the pressure within'the carbureter chambers againjreaches the predetermined point, the valves are closed.

. I have illustrated and described my improved ca-rbureter'in deta-il in the form preferred by me on account of its simplicity and economy. I am, hovvever aware that it is capable of considerable variation in structural details, ,without departing from my invention.
