RESERVOIR Patented Jan. 3 1893.

MINARD A. POSSONS AND HOMER L. CARROLL, OF CLEVELAND, OHIO.
RESERVOIR.
SPECIFICATION forming part of Letters Patent No. 491,023, dated January 31, 1893.
Application filed November 30, 1891. Renewed December 20, 1892- Serial No. 455,840. (No model) To all whom it may concern:
Be it known that we, MINARD A. PossoNs and HOMER L. CARROLL, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Reservoirs; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to improvements in safety-reservoirs especially well adapted for use in connection with vapor-burners, and comprising two chambers, a primary-chamber, and a secondary-chamber located directly below said primary chamber, the gasoline or liquid being fed from the primary chamber to the secondary-chamber, and the latter being provided with a valve or valves for distributing the liquid as desired.
Our invention consists more especially in a pneumatic reservoir, having suitable means for insuring an air-space inthe primary-chamber above the liquid level, and having suitable means for controlling the level of the liquid in the secondary-chamber and guarding against any serious results that might accrue by the expansion of the gasoline or liquid and over-supply of liquid to the secondary-chamber. Gasoline, for instance, is exceedingly variable in density according to the variations in its temperature, and with the reservoir heretofore devised the expansion of the gasoline was not only a great source of annoyance, but extremely dangerous, in that it would ascend by capillary attraction, and spread itself about the outside of the reser- V011.
In the accompanying drawings, Figure 1 is a side elevation of areservoir embodying our invention, showing the internal construction partly in elevation, and Fig. 2 is a plan of the same, portions being broken away to more clearly show the construction.
A and A represent, respectively, the primary and secondary-chambers of the reservoir closed top and bottom, respectively, be-
ing separated by a partition or diaphragm, A
B and 0 represent, respectively, air-tubes or pipes located at the filling side of the reservoir, the former establishing open communicationbetween the external atmosphere and the chamber as shown, trap D discharging into the upper part of chamber A.
Trap D, at its inlet-end, terminates in a lateral branch, E, that in turnterminates in a funnel, F. Y
Diaphragm A is provided, at the filling side of the reservoir, with an orifice, a, for feeding liquid from the primary to the secondarychamber, and to the underside of partition or diaphragm A is secured, in any suitable manner, a. depending arm, G, to which is fulcrumed, as at h, a tilting-lever, H. Lever H, at one end, carries a float, I, and, at the other end, has preferably pivotally connected therewith the upright stem,K, of a valve, K, the latter being adapted to cut off or open the supply of liquid to the secondary-chamber, as hereinafter more fully described, there being preferably provided a small upright pipe or tube, M, extending through diaphragm A at orifice a, as shown, and secured to the diaphragm in any suitable manner, the upper end of this pipe or tube constituting a seat for valve K. Pipe M has secured within it preferably one or more horizontal perforated diphragms m adapted to suitably embrace the stem of valve K and maintain the verticality of the same. In the normal position of parts valve K is elevated from its seat.
The gasoline, or other liquid, as the case may be, is poured in at funnel F,the reservoir of course being held in a horizontal position when supplying the same,and the liquid passes through trapD into chamber A. Of course, in supplying the reservoir, the primary-chamber should not be filled completely, but preferably to about an inch from the top of said chamber, so as to leave a suitable air-space between the level of the liquid in chamber A and the top. of said chamber, to accommodate the expansion of the liquid in said chamber. To prevent chamberAfrom being filled beyond the desired level, we provide transverse imperforate partitions, A at the filling side of the reservoir, forming a chamber A partitions A being preferably soldered to the surrounding wall of chamber A. With such construction, in filling chamber A,of course imagining the reservoir placed in a horizontal position, for the purpose aforesaid,the liquid will close the open end of chamber A but cannot displace the air contained in said chamber, the walls of the chamber being imperforate as aforesaid and hence the air is retained therein, and the cubic area of chamber A should be equivalent to the air-space it is desired to have in the upper part of chamber A when the reservoir is righted. Hence, it will be observed that there is no possibility of over-filling the reservoir.
Air-tubes or pipes B and (J and valve K, as already stated, being located at the filling side of the reservoir and air-tube 0 preferably on tside the reservoir, and the maximum elevation of valve K from its seat being but little, perhaps a sixteenth of an inch, it will be observed that little liquid can obtain access to the secondary-chamber during the filling of the primary-chamber of the reservoir.
The liquid remaining in trap D forms a liquid-seal against the passage of air; tube B affords the desired air-pressure to give fluency to the liquid in chamber A when discharging-valves V are opened, and tube 0 affords l ondary-chamber, and an air-tube or pipe esthe desired air-pressure to give fluency to the liquid in chamber A.
It is not desirable to carry more liquid in the secondary-chamber than about one-third of the capacity of said chamber, and the ar-' rangement of parts is such that float I and the lower end of air-tube or pipe 0 have the proper elevation relative to the desired liquid level in said chamber, so that as the liqui-d in said chamber rises above the desired level, from an over-suppl y due to a more rapid feed of the liquid from the primary to the secondary-chamber,resulting from an expansion of the liquid in the primary-chamber,such abnormity in the level of the liquid is checked by the elevation of floatI actuating lever H and closing valve K, thus cutting off further supply of liquid to the secondary-chamber until the liquid in said lastmentioned chamber has again assumed its normal level.
0 represents an air-tube that is in open communication with the external atmosphere near lateral branch E and extends thence to the diagonally opposite end of chamber A and is in open relation with the latter. Tube 0 performs no function except in emptying the reservoir through funnel F, in which case trap D serves as a siphon, the reservoir being held in such a position that tube 0 will supply the desired air-p'ressure to facilitate the emptying of the reservoir.
