To all whom it may concern.
Be it known that I, JAMES 8. Banner, a citizen of the United States, and a resldent of the city of Portland, county of Multnomah, and State of Oregon, have nvented a new and useful Improvement 1n Carbureters, of which the following is a speclfication.
My invention relates to carbureters of the type which produce the fuel mixture by passing a current of air over an atomlzer, or other fuel-oil feeding device, so as to cause the air to become charged with oil vapors.
As is well known, the difliculty generally experienced in carbureters is the obtaining of a properly balanced intermixture of gas and air. To accomplish this result, means have been provided for increasing the volume of air when a strong suction has a tendency to cause an excess of oil vapor, But such means, on the other hand, have a tendency to admit an excessive volume of I air which must be balanced by a larger volume of oil vapor. Hence the purposeof my invention is to provide means whereby the oil feed is automatically controlled by the speed of the engine.
I attain my purpose by using for the control of the flow of fuel-oil into the atomizer, or other fuel-oil feeding device, located in the mixing chamber, a valve controlled by means operating like a centrifugal governor, and using the suction of air through the mixing chamber, induced by the charging stroke of the engine, as the force for actuating the governor.
I accomplish these and other incidental objects by the use of the devices illustrated in the accompanying drawings, in which:
Figure 1 is a vertical section of my carburetor, showing also a portion of the manifold leading to the engine cylinders, and the feed pipe connecting with the fuel storage tank; Fig. 2 is a horizontal section taken approximately on the line 22 of Fig. 1; and Fig. 3 is a detail of the needle valve showing the port which revents said valve being entirely closed w en the needle is seated.
The shell, a, of my carbureter is made with a lower flange b, an upper flange c, and an exterior water-jacket d, the outlet and inlet of which are not shown in the drawings. The lower end ofthe shell, a,;
is further provided with an interior collar e, which forms a seat for a cylinder f. A float chamber 9 is provided on its upper end with a flange It, which abuts against the flange b, the two flanges being bolted together'by the bolts 2'. To insure a'tight joint the gasket, j, is used. The float chamber 9 is of annular form, the interior and open portion, 7a, connecting the cylinder,'f, with the atmosphere. A centrally located bearing m is supported in axial alinement with the cylinder, f, by the arms nfthe latter extending from the walls of the annular opening 70. The upper end of the bearing, m, is open, the lower end is closed except for a hole through which the stand-pipe, 0, extends, and an agate bearing, p, is mounted on the inner face of said bearing m. The pipe, 0, forms a direct connection between the float chamber, 9, and the bearing m. See Fig.1. Said pipe extends upwardly some distance above the lower end of the cylinder m, so that the gasolene will not overflow. A feed pipe, 9, connects the fuel tank (not shown) with the interior of the float chamber 9. A float, 1', which should be visible through some convenient glass indicates the amount of fuel present in the float chamber at any time. See Fig. 1.
A valved connection regulates the flow from the pipe 9 into the float chamber, as follows: A needle, 20, is mounted on an arm, 21, the latter pivotally mounted between the ears 22 on the floor of the float chamber. A spring, 23, normally holds the needle down, thereby closing the valve and cutting off the inflow. The arm, 21, is provided with a bifurcated end, the members, 24:, of which bear against the lower surface of the floor 1'. As the gasolene in the float chamber is drawn out through the pipe 0, the float, T, will drop to a lower level, depressing the arms 24, and thereby elevating the needle 20. Theinflow of gasolene from the feed tank will then raise the float, 1", and cause the needle 20 to again close the valve. In this way, a'constant supply of fuel is maintained in the float chamber and is prevented from overflowing the pipe 0.
The cylinder, f, is adapted to be inserted inside the shell, a, and is held in place on the collar 0. Said cylinder is further provided with inwardly extending, obliquely inclined deflector-wings, t, as shown in Figs. 1 and 2.
A cylindrical body, a, made with a coned portion '0, and a cylindrical lower end '0' of decreased'diameter is inserted in the cylinder f, so that sa1d lower end 11' will bear 1 entirely closed.
made with a in the agate ring bearing p. The body, 24, is-

' dropped over the shank of the needle, .will
seat itself on the collar w. Mounted on the disk, 5, are two pairs of diametrically opposed 'ears 6. Pivotally mounted in each spr ng 9 may air of ears is a bell-crank 7, each bell-crank being made with weighted upper arms, and
the lower arms being formed as toes which project under a collar 8, the latter being pinned onto the shank of the needle :1 These bell-cranks act as ball governors to raise or lower the needle A coil-spring 9, encircling the shank of t e needle y, bears on the collar 8 and normally holds said needle in its lowermost position. A plug end, 10, adapted to fit the upper end of the body u, forms a bearing for an adjusting screw 11, the latter being made with an enlarged cylindrical bottom, 11 cored out so as to fit over the spindle of the needle 3/, and adapted to bear on the coil-spring 9. A head, 11', on the upper end of the screw, 11, affords a convementmeans for turning the latter. B turning the screw, 11, the
' e compressed to any desired degree. A collar, 12, fast on the plug-end, 10, is provided with an annular groove containing the ball-bearings 13. A ring 14,
supported b the arms, 15, resting on the upper end 0 the cylinder encircles the collar 12 and provides a bearlng surface for the bearings 13. The flange, c, of the shell, a,
is bolted to the flange of the manifold, 16, a gasket, 0', being placed between the flanges to insure a tight joint. A hand-hole 17' in the manifold, 16, provides a means of easy' access to the adjusting screw 11.
The action of my carbureter is as follows: The spring 9 will normally hold'thc needle y in its lowermost position. A certain amount of oil vapor will rise through the .port, 3 into thebody u, so that when the engine is turned over, the draft created through the manifold, 16,-'will suck the oil vapor out through .the 'orifices, w, of the body, u, into the manifold to the engine cylinders. The continual suction through the ,manifold, whenthe engine'is running, will draw a currentof air up through the central.
port y at its lower end. Seeopening, of the float-chamber g. This current ofair will strike the wings, t, and be deflected against the fans, w, with the result that'the body, it, will be given a rotary motion in its bearings 12,13. As the speed ofthe engine increases, the rotary speed of the body, u, will also increase and the resultant partial vacuum created in the body, a, will suck the fuel up through the port y.
The partial vacuum in this case is formed b the centrifugal throw of the air out t rough the orifices m. When the engine speed has reached a certainpoint, the ballgovernors, 7, will be thrown outwardly, thereby raising the needle, y, and allowina freer feed to be madefthrough the va ve opening. After a predetermined speed of the-engine has'been reached, the ball-governors will contact with-the walls of the body a, and any further opening of the valve will be prevented. higher speed of the engine, the sameopen ing of the inlet valve will be maintained. In
this way, the mixture of air and'oil vapor will be controlled automatically by the speed of the engine, and no adjustments from the throttle will be necessary.
