WILLIAM L. BUBIB, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE-HALF TO OSCAR W. EPPERSON, OF LOS ANGELES, CALIFORNIA.
AIR-INLET VALVE FOR CARBURETERS.
Specification of Letters Patent.
Patented Nov. 26, 1918.
Application filed November 21, 1917. Serial No. 203,253.
- To all whom it may concern:
Be it known that I, WILLIAM L. BUBB, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Air-Inlet Valves for Carbureters, of which the following is a specification.
My objectis to provide an improved air valve for the inlet of a carbureter and to provide simple means for adjusting the spring tension of the valve, and my invention consists in the novel features herein shown, described and claimed.
Figure 1 is a side elevation of a carbureter with an air valve involving the principles of my invention in position for use, parts being broken away and shown in section to illustrate the details of construction.
Fig; 2 is a side elevation of my improved inlet valve removed from the carbureter.
Fig. 3 is an end elevation as seen looking in the direction indicated by the arrow 3- in Fig. 2.
The carbureter 1 is attached to the intake end of the manifold 2 and has a drain valve 3, a fuel connection 4, and butterfly valves 5 and 6, as is usual. The air intake passage 7 extends through the nipple 8 in which the valve 5 is mounted. The open end of the nipple 8 is usually circular.
My air inlet valve 9 is adapted for connection to the nipple 8. The casing 10 has a rectangular part 11 and a round part 12, the round part being adapted to fittightly upon the nipple 8 and the square part bein adapted for the support and operation of the wing-valve 13. The body of the valve 13 is rectangular in elevation, being higher than its width, as seen in Fig. 3, and is adapted to fit closely but loosely and freely in the rectangular'opening in the easing. The upper part of the valve 13 is thickened to form bearings 14 and 15, there being a notch 16 between the bearings. Bearing openings 17 and 18 are formed in the casing in line with the bearings 14 and 15, and a pivot pin 19 is inserted through the bearing 18, then through the bearing 15,
then through the coil spring 20 which is disposed in the notch 16, then throughthe bearing 14 and through the bearing 17 The spring 20 has one end 21 engaging the inner face, of the casing and the other end 22 of the-spring engages the valve 13, and a set screw 23 is inserted through the casing to engage theend 21 of the spring, so that when the screw has been adjusted to adjust the tension of the spring the tension of the spring tends to swing the valve to its normal vertical position and to resist the in-, ward swing of the valve, and the spring yields to allow the valve to swing inwardly. The spring is of considerable elasticity and may be adjusted to a nicety by manipulating the screw 23, and when the spring becomes weakened it may be re-adjusted. The valve 13 may swing freely outwardly under back pressure and back-firing and the like. Tongues are cut from the edge of the round part 12 and bent to form hooks 24 and 25 and'wires 26 and 27 engage thehooks and extend around parts of the carbureter to hold the valve in lace. The casin 10 is preferably made rom a piece of tu ing.
lVhen the engine is started, the valve will be closed and will open slightly, forming a resistance to the intake of the air, and as the speed of the engine increases, the spring 20 will yield and the extent of the opening will increase.
I claim:
1. The combination with a carbureter having a circular air intake nipple, of a casing having a circular part to fit the air intake nipple and having a rectangular outer end, tongues cut from the edge of the circular part of the casing and bent laterally, wires extending around the carbureter and around the tongues to hold the casing in place, a rectangular valve fitting loosely in the rectangular end of the casing; the upper part of the valve being thickened to form bearings, there being a notch between the bearings; a coil spring in the notch, a pivot pin inserted through the bearings, through the coil spring, and through the sides of the casing; one end of the spring engaging the casing and the other end of the spring engaging the valve; and a set-screw inserted dowmvardly through the casing to engage one end of the spring.
2. The combination with a carbureter having a circular air intake nipple, of a casing having a circular part to fit the airintake nipple and having a rectangular outer end, a rectangular valve fitting loosely in the rectangular end of the casing; the upper part of the valve being thickened to form bearings, there being a notch between the gaging the valve; and a set-screw inserted bearings; a coil spring in the notch, a pivot downwardly throuqh the casing to engage pin inserted through the bearings, through one end of the spring.
the coil spring, and through the sides of the In testimony whereof I have signed my 10 5 casing; one end of the spring engaging the name to this specification.
casing and the other end of the spring en- 7. L. BUBB.
