Specification of Letters Patent.
mpplication filed February 26, 1316. Serial No. 80,572.
To all whom it may concern: p
Be it known that I, WILLIAM REID, a citizen of the United States, residing at Chicago, in the county'of Cook and State of liinois, have invented a certain new and 11 ful Improvement in Carbureters, of which the following is a full, clear, concise and exact description reference being hadto the accompanying drawing, forming a part of this specification.
My invention relates to carbureters and has for its object the provision of means for automatically lifting or forcing fuel from a fuel reservoir to the fuel chamber of the carburetor when the fuel reservoir is located below the normal fuel level of the carbureter.
Incarrying out this object I contemplate the provision of means for utilizing the suctlon produced by the internal combustion engine with which the carbureter is associated to provide a vacuum or reduction of pressure above fuel in the fuel chamber of the carbureter, so that I obtain a difference of pressures between the fuel located in the carburetor and the fuel located in the'supply f reservoir. The supply reservoir contains/a vent opening which subjects the fuel c0ntained therein .to atmospheric pressure whereby the fuel is forced from the supply reservoir up into the fuel chamber of the carbureterj By my invention the carbureter This housing may/be made with a glass i connected with a conduit 16 terminating at need not be drilled, bored or in any other way mutilated or changed to produce this reduction of pressure within the fuel chamber thereof.
These and other features of my invention will be more fully pointed out in connection,
with the accompanying drawing, which illustrates the device ofmy invention.
In the drawing, 1 illustrates a carbureter of any design connected by means of the flange usually provided thereon to the intake manifold 2 leading to the cylinders of the internal combustion engine. The carbureter is provided with the usual fuel chamher 3 and main air intake opening 4. The drawing illustrates a carbureter provided with a second air intake opening 5, commonly known as the auxiliary air intake port. Positioned around the carburetor isa casing or housing 6 which is preferably held between the flange of the carbureter and the. flange of the intake manifold, as illustrated.
front door 7, which is hinged at 8 to the base of the housing, the catches 9-9 serving to hold the door in closed position. The casing 6 is preferably made substantially air tight, so that it allOWS substantially no air to enter it, except through an intake opening 10 provided in one of the walls of the housing. The throttle valve of the carburetor may be controlled by means of the wire 11 extending through the wall of the housing, or the shaft upon which the throttle valve is mounted may extend through the, rear wall of the housing and be there connected with a wire similar to the one illustrated at 11. Similarly the valve for controlling the intake port 4 is controlled by means extending through the housing. The fuel or float chamber 3 receives its supply of fuel through the conduit 12, terminating at one end in the base of the fuel supply reservoir 13. This reservoir'is open to atmospheric pressure, as illustrated, so that when a reduction of pressure is produced within the fuel or fioat chamber of the carbureter, fuel will be forced upwardly through they conduit 12 and into the carbureter. As is well known, the interior of the fuel chamber 3 of all standard carbureters' is open to atmospheric pressure,
Patented (hot. as, rails.
determines the amount of vacuum or reduction of pressure which is to be produced within-the housing during the operation of the carburetor.
If it is desired to have a one pound reduction of pressure within the housing during the operation of the carburetor, the spring 15 is made .so that thevalve l l-is opened when there is produced within the housing a pressure which is one pound less than atmospheric pressure. The interior of the fuel chamber 3 will then be subjected to a pressure which is one pound less than atmospheric pressure, with the result that if the conduit 12 has free communication with the fuel chamber the fuel will be forced upwardly into the same.
If desired, the intake opening 10-may be its other end adjacent the exhaust manifold of the engine or some other source of heat,
. and the intake manifold, but it will be readily understood that the housing may be clamped to the manifold above the flanges if the carbureter contains any mechanism which projects above the flanges.
Although I have illustrated the entire car bureter as being enveloped by the casing, I
wish it to be understoodthat to produce the desired reduction of pressure it is necessary only'to provide a housing around the intake port of the carbureter which has itsinterior' communicating with the interior of the fuel a chamber. In other words, it is not necessary to cover the entire carbureter up, although this, has its advantages in that the housing 1 can be clreaply made and that the entire car= bureter is subjected totthe warm air fed to it through the conduit 16.
Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
1. The combination with a carbureter having a fuel chamber and an air inlet port, of a casing surrounding said carbureter and having an air intake opening provided with an inwardly opening spring controlled valve, a fuel supply reservoir open to the atmosphere and positioned below said carbureter,
and a conduit for conducting fuel from said fuel supply reservoir to said fuel chamber.
2. The combination with a carbureter having a fuel chamber and an air inlet port, of a casing surrounding saidcarbureter and having an air intake opening provided with an inwardly opening valve, a fuel supply reservoir open to the atmosphere, and a con duit for conducting fuel from said fuel supply reservoir to said fuel chamber.
3. The combination with a carbureter having an air inlet port, of a casing surrounding said carbureter and having a restricted air intake port, a fuel supply reservoir opening to the atmosphere, and means for conducting fuel from saidreservoir to said carbureter.
In witness whereof Ihereunto subscribe my name this 23rd'day of February, A. D'. 1916. g a
WILLIAM REID.
