' Tool! whom it may concern:

Be it. known that I, JoI-rN Sh ner, a

citizen/of the United States, residing at Janesville, county of Rock, State of lViscon:

.sin, have invented certain new and useful Improvements n Carburetors, of which the bureter chamber.

following is a specification.

This invention relates to improvements in First, to provide an JIDPIOVBCl'Cl1ll)Ll1:Bl1I for explosion engines in Which the feed is autoearbureters.

Themaln ob ects of this inventlon are;

matically controlled by the varying running conditions of the engine.

.vide an improved carbureter embodying these advantages which is quickly and easily.

adjusted. Third, to provide an improved carbureter in which the parts are simple in pointed out in the claims.

structure and arrangement. ects, and ob ects relating to from the detailed description to follow.

I accomplish the objects of my invention following specification.

The invention is clearly by .the devices and means described in the defined and A' structure embodying the features of my invention is clearly illustrated inthe ac- ..companyingdravving, forming a: part 'ofthis specificatiomjn which: v

In the act-ere refer to similar parts throughout the several-views," and the-sectional views are taken looking in the direction of the little arro 'vs at-the ends of the section lines.

Referring tothe (lraivin the. carbureter chamber 1 1s connected to tier, not; here illustrated, by means ofthe passage2. The throttle valve 3 of the structure illustrated is of the plug type, and is I sh'oi'vn in the drawings in its-partially open Second, to prorawings, similar reference char-- position, the fuel inlet valve also being par--' 'tiall-y open, as. would be the case when the engine was runningat a normal speed.

The fuel .feeddevice preferably consists of a valve casing-4, which is threaded into a projecting nipple 5 on the side of the car- The valve casing is provided with a fuel inlet (S, which is connected to a suitablesource of supply, which is not here illustrated, as this connection. will be readily-understood.

' Within the casing 4 is a. casing bushing 7 having a slot-like port 8 therein. The valve 9 is provided with a slot-like port 10, adapted to be brought into register rith the port 8. This valve has a dist-barge passage 11. whiehis preferably provided with a conical delivery nozzle 12, projecting into the .earbureter chamber, the nozzle being preferably threaded into the passage, as illustrated, and projecting at, each side to form-shoulders 13', on which theloiver end of the spring '14 rests, this spring-being provided to perthe valve. The slot-like ports in the casing end in the valve are horizontally disposed so that by adjusting the valve longitudinally, the ports are brought more or less into regi.ster.' .a's conditions mayrequire. This longitudinal adjustment is affected, as stated, by means of the nut 15'.

i The nut 15 is preferably adjusted. by

means of the Worm 16 arranged in a suitable hanger, as -l7. on the arm-like bracket TSNyhich is carried by the valve.

Inthe operation of the device. the valve 9is rotti-ted or rocked so that its port. in

opening mdves lengthwise'of the casing port. -The advantage of this is thatby providing the adjustmenthfor the portage described,

very accurate regiil ation of the valve maybe had to control the damper. proportions of the the engine cylin-' air and fuelLWZThefuei vdlveand the throttle valve are connected to be operated together, preferably by providing the valves with arms 19 and 20, respectively. the arms being eon heated by a link 21,. '-Tl1is link is actuated by an air-actuated member 22. which, in the structure '1llustrated. 1s c-auhke' n ,form.

being IQClDI'OCHtlTiglY mounted upon the endv of the carburetensothatthe suction of the engine acting thereon will draw the cap inwardly and thus shut the valves. The parts are returned to their initial position by means of a suitable spring, as 23, which, in the structure illustrated, is connected to the yalve casing 41 and to an arm 24: on the stem the throttle valve. It will be understood that this spring can be arranged in various relations to accomplish the same results, its 10 primary object being to return the air-actuated member.

The member 22 provided with air inlet ports 25,'which are controlled by a valve 26, an are shaped slot and a setscrew 2-7, being provided for securing the valve in its adjusted positions. The port regulating valve Elli-is adjusted hand. This enables the adjustment of the air openings for the air-actuated. member,- so that the effect of the suction. thereon is regulated.

The valves, in the structure illustrated, are shown in their partially open position. In practice, the strokes of the engine are so rapid that the air-actuated member does not. complete its full stroke. and, in effect. remains in a certain position, depending upon the running conditionsof the engine. Below the nozzle 12 I preferably provide a drainor fuel discharge 28, which delivers 0 to a receptacle, as 29. The object of this is to prevent any accumulation of fuel in the carbureter chamber which would. vary. the explosion mixture.

By my improvement, I secure a carburetor which is automatically controlled by the engine. I have illustrated "the same in. the accompanying drawing in detail in the form preferred by me on account of structural simplicity and economy and the com-'cnicnce in assembling and disassembling the same and the convenience of adjustment. T. am, however aware that the embodiment of my invention illustrated and described herein may begrcatly modified in structure, and I desire to b'eunderstood as claiming the same broadly as Well as the embodiment illus- .trated.
