JAMES G. NO LEN, OF NEW YORK, N. Y.
-AUXILIARY FUEL RESERVOIR.
Application filed February 23, 1922. Serial No. 538,440.
To all whom it may concern:
Be it known that L-JAMES G. NOLEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Auxiliary Fuel Reservoirs, of which the following is a full, clear, and exact description.
The invention which constitutes the subloject matter ofthis application relates to a fuel supply apparatus for internal combustion engines, particularly those engines employed upon motor vehicles and the like, said apparatus being of that type in which a main supply. tank is employed frorn'which the liquid fuel is raised by suction into an auxiliary reservoir from which it falls by gravity through a suitable discharge to the carburetor.
larly to do with certain novel mechanism for controlling the admission of atmospheric air into, the auxiliary reservoir above the fuel therein after the same has reached a predetermined level and for establishing a communication of the upper end of this reservoir with the pipe leading to the vacuum producing means of the engine.
Further objects, advantages and features J of construction and operation will be more i clearly apparent from the detailed description below taken in connection with the accompanying drawing in which:
Figure 1 is a central vertical. section of the auxiliary reservoir showing the operative parts of the device, some of which are in cross section; I
- Figure 12 illustrates the position of the mechanism as the tank is being filled by vire tue of the reduced pressure in the upper part of the reservoir; I I Figure 3illustrates a front view of the dia phragm bearing upon. which the float rod is pivotally supported; I Figure ,4 illustrates a cross section of the valve employed to establish communication between the reservoir and the vacuum producing means on the one hand and. the reservoir and external atmosphere on the other;
Figure 5 is a longitudinal section of the valve illustrated in Figure 4.
closed in a surrounding vessel which is not The present invention has more particu-' Referring-to the drawing in detail. the' reference numeral lOdesignatesan auxiliary reservoir. This reservo r is preferably enillustrated herein and which is always under atmospheric pressure. Within the reservoir 10 isa housing 11 suitably secured as by bracket 12 to the cover of said reservoir. The reservoir is provided with an inlet port 13 and the housing with ports 14. To the inlet port 13 is connected a pipe 15 leading to the main fuel supply tank. Centrally positioned on the interior of the housing is an arm 17 upon which an anti-friction roller 18 is mounted. To the front face of the housing is secured, as by an annular flange 19,
and securing screws 20, adia'phragm 21 provided with a centrally located bearing 22 for the arm 23 of the float 24. The bearing 10 in connection with the enlarged portion 25 of the arm 23 constitutes a balland socket connection of said arm with the diaphragm 10.
Projecting from the enlargement 25 into the housing 11 is an extension 26 of the arm 23. This extension normally contacts with one side of the anti-friction roller 18, as clearly illustrated in Figure 2. However, when {the float 2 L raises, the extension rides over the anti-friction pressing the diaphragm 21 out- Wardl y, so that when the extension 26 passes beyond the dead center of the anti-friction roller 18 it gives an impetus to the movement of the float, thus shutting off the vacuum and establishing communication between the upper end of the reservoir and the atmosphere through the valve 27 to be presently described. v
The valve 27 comprises a casing 28 (see Figures 4 and 5), a conical seat 29, and a conical valve member 30 seated upon said seat 29. The enlarged end of the casing 28 is provided with a closure 31 screw-threaded or with a-port 35 adapted to register with a second port 36 in the casing 28 whenever the float 24 is in the upper dotted position indicated in Figure 1. The valve 30 is provided with a second port 37 which is adapted to register with a second port 38 in the casing 28 whenever the float 24 is in the upper dotted position, thereby establishing communication between the upper portion of the reservoir and the atmospheric air through pipe 39. An arm 40 is ,mounted upon the stem s1 of the valve 30, which arm 40 is connected 'to the arm 23 of the float by means of a link 42.
Briefly stated, the operation is as follows: The normal position of the float, is indicated in Figure 1. When the fuel recedes in the tank the float falls'proportionately passing over the dead. center indicated in full lines in Figure 1, to the lower dotted line position indicated also in said figure, and also indicated in full lines in Figure 2. As
the float passes dead center in its downward movement. the ports 35 and 36 begin I to register, thereby establishing communiherein shown and described, as
cation between the upper end of the reservoir and, the vacuum producing means through pipe 24. A reduction of pressure in the reservoir causes fuel to be fed from the fuel supply tank through pipe 15 into the reservoir. Simultaneously with the reg; istering of the ports 35 and 36, the ports 37 and 38 will be moved to unregistering position, thus closing the reservoir to the atmospheric air. In filling, the reverse operations take place, as will be readily understood.
It is to be expressly understood that I do not limit myself to the exact construction many changes may be made in points of detail and other embodiments resorted to Without deviating from the true spirit and scope of my invention.
