To all whom it may concern: 1
Be it known that I, MEYER ABRAHAJW SIMON, a citizen of the United States, residing at St. Louis, State of Missouri, ha invented a new and useful Combination Carburetor Choker and Switch Mechanism, of which-the following is a specification.
My invention relates toan improved combination carburetor mechanism, and consists in the novel design, combination, and arrangement of parts herei inafter more fully disclosed. Y
An object of the invention is to provide a simple, convenient, and effective means of simultaneously excluding the cold outer air from mixing with the fuel in a carburetor .and controlling an electrical resistance circuit for the preheating of said fuel Another object of the invention is to provide an essential mechanical arrangement whereby a heretofore distinctly .double manual operation is reduced to a single manual operation, and thus, through the fractional time element involved in its operation, addvitally to its resultant success.
illustrated in the accompanying drawing, in which I I Figure 1 is a detailed view in perspective of the device showing the choker and switch mechanism in normal position. Figure 2 is choker and switchthrough switch plate 3 and the dash board 1' permits thecontlnued passage .therethrough of the choker rod 8Iwhich penetrates and extends slightly beyond the instrument board 2. A knob 10 securedto theupper extremity of the said choker rod constitutes the handle or gripping means'by which the device is manually operated. The lower extremity thereof is bent into an elbow .11 to engage the upper arm 12 of 'a'bell-cr'ank lever 13 to which it is secured by'a cotterpin 14, the said bell-crank member being pivoted in a bracket 15 secured to the dash. The lower arm 16 of the bell-crank lever engages the upper end of a pull-wire 17 which is fastened at its lower end to a lever 18 adapted in beror attain these objects bythe mechanism.
to actuate the butterfly torsion spring 21 mounted on the choker the lever 18 and at its other end a stop 23. Mounted on the choker pull-rod .8, at a point between'the elbow 11 and the contact switch late 3, is a circular contacting memiiead 24 comprising a central'disc or core 25 of insulating material penetrated by the choker ull-rod upon which it is adapted to be slida le, and an annular metallic rim 26 spun or pressed upon the outer periphery of said central insulating disc. A compression spring 27 interposed between the outer a vertical section of the combined mechaface of the contacting member 24 and a stopnism and the supporting framework therefor. Figure 3 is a diagrammatic view illustrating a heating resistance and battery supply in circuit with the make-and-break choker switch. 4
Similar numerals refer to similar parts throughout the several views.
In the embodiment of the inventioriillustrated in the drawing, the dash board li and instrument board 2 constitute the supporting structure or framework'for the combination contact surface 7 inclined substantially at right angles to a movable choker pull-rod member 8 passing through the eenterthereof and spaced therefrom. ,A slot extending pin 28 located adjacent to the elbow tends to actuate said contacting member forward in the direction of the terminal contacts 4.
But a second stop-pin 29 maintains said con-' tacting member at a point normally out of contact with 'the aforesaid terminal contacts 4, as shown. Lead wires 30 and 31 place the switch mechanism in circuitwith an electrical'heating resistance 32 and a source of supply 33 shown in the diagram.
choker valve 19 in v the carburetor 20- against the tension of a When the choker rod 8 is pulled outward to its fullest extent against the tension of l the torsion spring 21, the contacting member 24 is drawn inward therewith to bear flush against the terminal contacts 4, thus closing or completing the electrical circuit through its metallic conducting rim 26.
The compression spring 27 isadapted to operate as a compensating member,that is, to make up or compensate for a possible variation in the distance of movement ofthe chokerpull-rod 8. When the choker rod is released, it is instantly drawn back to its normal position 'by the tension of the torsion spring 21 which results thereby in the breaking of the electrical circuit and the reopening of the air. inlet to the carburetor.
The essential feature of my device lies in its reduction to a single operation what formerly constituted or required two distinct operations to perform. In other words, it was the usual practice to first manipulate a mon'ientary contact switch to energize a heating resistance circuit to preheat the fuel or a gaseous mixture thereof, and then immediately uponreleasing such switch to operate the choker in conjunction with the starter switch for starting the engine in cold weather. This distinctly double operation, in passing from the switch to the choker, resulted in a vital momentary loss of time which permitted the heating resistance to cool sufficiently to reduce greatly its value as an aid to starting in cold weather.
The advantage of closing the air inlet to the carburetor simultaneously with the prelimit myself, therefore, to the exact details of construction shown and described, but
What I claim and desire to secure by Letters Patent, is
1. The combination with a carburetor choke mechanism of a simultaneously cooperating switch member adapted to control an electrical heating resistor disposed in the path of flow of the fuel in an internal comustion engine.
2. The combination with a carburetor choke mechanism of cooperating means for controlling an electrical heating resistor dis posed in the fuel supply circuit ofan internal combustion engine.
3. A combination carburetor choking and switch mechanism, comprising a pull-rod member, means for connecting said pull-rod member with the carburetor choker valve,
and a switch mechanism adapted to be opvalve.
upon said pull-rod member and insulated therefrom, and spring compensating means for said contacting member.
5. A combination carburetor choking and switch mechanism, comprising a pull-rod member, means in connection with said pullrod member for controlling the air inlet to a carburetor, stationary switch contacts mounted on either side of said pull-rod member and spaced therefrom, and-a contactingmember adapted to be mounted upon said pull-rod member and insulated therefrom.
6. A combination carburetor choker and switch mechanism, comprising a supporting 'structure,aswitch plate secured thereto, terminal contacts mounted upon said switch plate, and means for simultaneously closing the electrical circuit between said terminal' contacts and closing the air inlet to the carburetor.
7. A combination carburetor choker and switch mechanism, comprising a supporting structure, a switch plate secured thereto, terminal contacts mounted upon said switch plate, a pull-rod positioned between said terminal contacts and spaced therefrom, a contacting member carried by said pull-rod, means for operatively connecting said pullrod with the carburetor choker valve, and
manual means for actuating said pull-rod. 8. A comblnationcarburetor choker and structure, a switch plate secured thereto, terminal contacts mounted upon said switch plate, a pull-rod positioned between said terminal contacts and spaced therefrom, a contacting'member carried by said pull-rod, compensating means for said contacting member, and means for operatively connecting said pull-rod with the carburetor choker MEYER ABRAHAM SIMON.
