STORAGE TANK FOR VOLATILE LIQUIDS Filed Dec. 29. 1927 2 Sheets-Sheet 2 Patented M... 29, 1932 UNITED STATES PATENT, OFFICE CLAYTON 1'. DAY, NEW YORK, N. Y ASSIGNOB TO CHICAGO BBIDGI & IRON 00., A CORPORATION 01 ILLINOIS :TOBAGE TANK FOR VOIIATHIE LIQUIDS Application filed December 29, 1921. semi no. 243,220.
This invention relates to improvements in storage tanks for volatile liquids, and more especially to such a tank of the breather type to permit expansion and contraction of 6 the gases in the vapor space above the liquid without loss. For example, in tanks of this type used for the storage of gasoline, crude oil, and other volatile liquids, there is a considerable amount of gas in the space above the liquid. Variations intemperature cause changes in this volume and if the volume of the container cannot change accordingly there is an escape of gas and consequent loss.
One of the features of my invention is the provision of such a tank requiring no me chanical valves and presenting no drainage problem. The tank, nevertheless, permits expansion and contraction of the gases in the vapor space above the liquid while eflectually sealing the tank at all times against the escape of ases into the atmosphere.
nother feature of my invention is the provision of improved means for guiding the roof in its vertical movements.
Another important feature of my invention is the fact that it may be employed in connection with standard tanks now in common use not of the breather type. Such tanks may be easil converted into my improved storage tank by slight adaptations.
Other features and advantages of my invention will a pear more fully as I proceed with my speci cation.
In that form of device embodying the features of my invention shown in the accompanying drawings, Figure 1 is a vertical sectional view, Fig. 2 is a fragmentary view similar to Fig. 1 showing the liquid seal on an enlarged scale, Fig. 3 is a fragmentary view similar to Fig. 1 on an enlarged scale show ing the central guide for the movable roof, Fig. 4 is a view taken as indicated by the line 4 of Fig. 1, Fig. 5 is a view similar to Fig. 1 showing a modified form, Fig. 6 is a view similar to Fig. 2 showing a modified form, and Fig. 7 is a view similar to Fig.2 showing a modified form of the vertical guide.
As shown in the drawings, the tank comprises the usual cylindrical shell 10 with the bottom 11. Such tanks not of the breather example, may be water in warmer climates or brine in colder ones. The roof 12 is rovided at its peripher with a depenn flange 12 havin its ower, edge immerse 1n the liquid 14, t us providing a liquid seal between the shell and the roof.
Suitable guiding means are provided to gulde the roofin its vertical movements.
uch means may include members such as the rollers 15 carried by the roof and enga 'ng the inner wall of t e shell 10. The ro ers 15 may be supported in any suitable manner as, for example, b means of the diagonal hanger bars 16'an the vertical rod 17 provided with turn buckles 18 to raise or lower the rollers 15to swing the rod 16 on the pivots 19 to bringthe rollers 15 into" correct adjustment against the shell 10. There may also be provided central guiding means ineluding a post 20 the u per end of which is telescopically embrace in the cylindrical guide 21 on top of theroof (see Fig. 3
In Fig. 5 I have shown a modified formin which the trough for the liquid seal is located inwardly a short distance. In this modified form, the top of the shell 110 may be provided with a narrow stationary inwardly extending flange 110 and the trough 113 may be at the inner margin of this flan e 110.
In such construction the conical roo 112 is preferably provided at its periphery with an upwardlyextending flange 112 and this in turn with an outwardly extending flange 112 carrying at its periphery the depending flan 112 with its lower edge immersed in the liiiuid 114 in the trough 113. In converting a tank with a stationary conical roof into my improved breather type of tank, it may be easier to cut the roof on a line in a little distance from the outer ed e of the tank instead of at the ver outer e ge.
In the modifie form shown in Fig. 7, I have shown additional guiding means comprisin the vertical uide members 24 and the rol ers 24 mounte on the periphery of the roof, said rollers moving up and down on the guides 24 with the movement of the roof 12.
As shown in Fig. 2, the roof 12 may be provided with a projecting eave 12 to prevent rain water from entering the trough 13.
While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention disclosed in the appended claims, in which it is my intention to claim all novelty in my invention as broadly as possible in view of the prior art.
lVhat I claim is new, and desire to secure by Letters Patent, is:
1. A storage tank comprising; a substantially cylindrical shell; a vertically movable roof; a liquid seal between the shell and the roof of relatively slight height with respect to the height of the tank; and guiding means for guiding the roof in its vertical movements, said guiding means including members carried by the roof engaging the inner wall of the shell and said guiding means extending inwardly a substantial distance from the margin of the roof to constitute efiective brace elements for the latter.
2. A storage tank comprising; a substan tially cylindrical shell; a vertically movable roof; a liquid seal between the shell and the roof; and guiding means for guiding the roof in its vertical movements, said guiding means including members carried by. the roof engaging the inner wall of the shell, said members being supported from said roof by diagonal outwardly, downwardly extending hanger bars and vertical adjustable rods connecting the outer ends of said hanger bars to the roof, said diagonal hanger bars being extended inwardly a distance from the margin of the roof to constitute efiective brace elements for the latter.
3. A storage tank comprising; a substantially cylindrical shell; a vertically movable roof; a liguid seal between the shell and the roof; gui ing means for guiding the roof in its vertical movements, said guiding means including members carried by the roof extending a substantial distance inwardly from the margin of the roof to constitute effective braces for the latter and engaging the inner wall of the shell; and means for adjusting said last mentioned members individually inwardly or outwardly to vary the pressure of tlfieiiengagement with the inner wall of the s e 4. A stora e tank comprising a substantially cylindrical shell, said shell at the top thereof having a stationary roof portion extending inwardly from the margin, a vertically movable roof substantially inwardly of said (portion, one of said parts having a downwar ly extending flange, the other of said parts having a trough adapted to contain liquid engaged by said flange.
5. A storage tank comprising a substantially cylindrical shell, a vertically movable roof substantially of conical form, a liquid seal at the junction of the shell and roof, guide means carried 'by the roof and enga ing the shell below the liquid seal, said gui 0 means extending inwardly and connected to the roof at a substantial distance from the margin thereof so as to form an effective brace means, and a central guide means coacting with the brace means to preserve the shape of the roof, comprising a cylindrical guide member extending upwardly from the apex of the roof and post means within and engaged by said cylindrical member.
In witness whereof, I have hereunto set my hand this 12th day of December 1927.
