Oct. 9, 1956 J. A. LINDOW CARBURETOR VALVE WITH ADJUSTABLE STOP Filed Aug. 15, 1950 INVENTOR.
BY AW United States Patent CARBURETOR VALVE WITH ADJUSTABLE STOP Joseph A. Lindow, Pittsburgh, Pa.
Application August 15, 1950, Serial No. 179,449
1 Claim. (Cl. 251-285) This invention relates to new and useful improvements in fuel regulating means for internal combustion engines, particularly for use in automobiles, which is adapted to be manually operated from the dash of the vehicle under certain operating conditions, particularly when the vehicle is coasting down grades, and to automatically return to its normal setting in response to operation of the foot accelerator.
it is among the objects of the invention to provide a fuel regulating means which shall effect substantial savings in the use of fuel and also act to retard the vehicle by increasing the compression of the motor when the control is effected.
The invention will become more apparent from a consideration of the accompanying drawing, constituting a part hereof, in which like reference characters designate like parts, and in which:
Fig. 1 is a top plan view of a carburetor bracket showing the fuel regulating device attached thereto; and
Fig. 2 is a side elevational view taken along the line 22 of Fig. 1.
In the drawings, numeral 1 designates a bracket which is attached to a carbureter for connection to the intake manifold of an internal combustion engine, there being two air ducts designated by numeral 2 in which are dis posed butterfly valves 3 that are mounted on a shaft 4 that is operable from a fixed stop to open position by means of a foot pedal control or throttle 5. Throttle 5 is the conventional spring controlled foot throttle which is spring actuated at 5a to close. It is limited in its closing movement by stop 6 fixed on shaft 4 that abuts flanged head 8, of a pin 7, the pin extending through an opening in a stationary bar 9a. A coil spring 9 abuts the head 8 and the stationary bar 9a. Disposed on the spring is a sleeve 10 on which is mounted a link 11 connected to the sleeve 10 by a pivot pin 12. Link 11 has a bifurcated end 13, as shown in Fig. 1, the arms of which are connected by the pivot pin 12 and the cross-bar 13a constitutes an abutment for the pin 7.
In normal operation the flanged head 8 of pin 7 constitutes an abutment for the stop 6 to maintain the butterfiy valves 3 in a partially open position that permits the inflow of air to the carbureter, and in this position the engine has a minute fuel supply, this being the set position for idling of the motor when the vehicle is standing still. In accordance with the present invention, the stop position of the head 8 of pin 7 is altered to permit complete closing of the butterfly valves 3 by pulling the link 14 which extends to the dashboard. This causes the cross-bar 13a of link 11 to be tilted, as shown in dotted lines in Fig. 2, and permits the end of pin 7 to extend upwardly, thus clearing the stop 6 of shaft 4 and permitting the shaft to turn to the complete closed position of the butterfly valves 3.
The shaft 4 is normally connected With the fuel control valve to the carbureter so that when the butterfly valve is closed the fuel supply will be completely shut off. In this shut-01f position of both the air and fuel supply, which is under the control of the operator when coasting down grades, there would be a slight tendency to form a vacuum in the intake manifold. When the car is again operated for cruising speed by operating the accelerator foot pedal, spring 5a will return the regulator link 14 to normal position with cross-bar 13a abutting the end of pin 7 by virtue of its connection with shaft 4 to prevent complete closing of the butterfly valve when the foot accelerator is manipulated.
It is evident from the foregoing description of this invention that fuel regulating devices made in accordance therewith permit of complete closing of the butterfly valve, thus shutting off the air and fuel supply to the engine. The normal function of the carbureter system is restored automatically when the operator depresses the foot accelerator after the vehicle has run downhill. It is only when the regulator is operated manually that the fuel shut-off mechanism is in operation.
Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.
I claim:
In combination with a pivoted throttle valve for a carburetor, means for biasing said valve toward closed position, a stop arm movable with said valve, an axially movable pin having at one thereof a flanged head mounted in the path of movement of said stop arm, an abutment for the other end of the pin pivotally mounted for movement into and out of alignment with said pin, said abutment when in alignment with the pin cooperating with the stop arm to prevent complete closing of the valve, a spring biasing said pin in the direction away from said abutment, and manually operable means for displacing said abutment out of the path of movement of said pin to permit complete closing of the valve.
