CARBURETOR CONSTRUCTION.

Application. filed September 9, 1927.

lvly invention relates to improvements in carburetor constructions. and it consists in the combinations, constriu-tions and arrangements herein described, and claimed.

An object of my invention is to provid t means whereby all leaking or flow of liquid into the carburetor of an internal combustion engine may be stopped.

A further object of my invention is to provide a device of the type described in which this means may be actuated from the instrument board of the automobile.

A further object of my invention to provide a device of the type described by means of which great damage would be prevented from happening to the automobile should the automobile catch on tire the supply of gasoline is completely shut oil from the carburetor.

A further object of my invention is to pro Vide a device of the type described which will also aid in preventing the automobile from being stolen as the automobile could only be driven a short distance until the gasoline in the carburetor is consumed and the automobile would then stop, owing to the fact that the supply of gasoline is shut off from the carburetor.

Other objects and advantages will appear in the following specification. and the novel features oi the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings. forming part oi this application, in which Figure 1 is a sectional view of my device as applied to a carburetor, and

Figure 2 is a section along the line 2 -2 of Figure 1.

In carrying out my invention, I make use of a carburetor 1 having a float 2 and a valve 3 arranged to engage with a 'alve seat 4 for closing the passage in the supply pipe 0.

I provide a. housing 6 having a weight 7 movably disposed therein. A resilient rod 8 is rigidly secured to the weight 7 and extends upwardly through the housing 6 and through a flexible tube 9 and an instrumentboard it). A button or knob 11 is rigidly secured to the free end of the resilient rod 8.

Serial No. 218,517.

The housing 6 is disposed in alignment with the valve 3. A spring 12 is disposed in the housing (5 concentric with the resilient rod 8 between the upper end of the housing and the weight 7. A latch member 13 is pivotally secured at 1 1 to the instrument board it) for a purpose hereinafter described.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The float 52 and alve 3 simulate an ordinary float valve of an ordinary carl'iuretor 1. The float valve is adapted to permit a predetermined amount of gasoline to enter the carburetor through the teed pipe 5. Let us assume that the user wishes to park the car. By moving the locking member 13 to one side about its pivot. the weight 7 may be moved downwardly into engagement with the vaive 3 by pressing the knob 11 and by the aid oi? the spring 12. By forcing the weight 7 downwardly as far as possible, the valve 3 will be forced into engagement with the alve seat 4, thus positively closing the passageway in the feed pipe 5. The spring 12 is suiiicient to hold the weight 7 in ei'igagementwith the valve 3, thus preventing the passage of gasoline into the carburetor.

The weight 7 may be removed from the valve 3 by pulling outwardly upon the knob 11 a suilicicnt distance to allow the locking member 13 to freely move between the knob and the instrument board. It is obvious that carburetors differ in construction. However. in the ditterent carburetors the flow oi" the gasoline into the carburetors is controlled by valves which are actuated by floats. 'lhcretore, the structure may vary to agree with the various types of carburetors without departing from the spirit and scope of the invention.

. t will be understood that my device may be embodied in. old carburetors as well as new, and may be attached to the ignition switch. whereby it will be operated automatically.

I claim:

The combination with a carburetor and an instrument board, a i'eed pipe for said carblu'etor, and a float valve arranged to vary the amount of liquid passing into said carburetor. ot a weight member a rrangcd to ltltl engage With said flout valve for actuating :id float valve for positit'el stoppin; the How of liquid into said (:m'buretor, a resilient rod having one end secured to said weight member, a knob secured to the other end of said resilient rod, said resilient rod extending through said instrument board.

and a member pivotally mounted upon said instrument board and arranged to he passed heneath said knob For holding said resilient 10 rod outwardly and for holding said weight member away from said Valve.
