16 Claims. 1

This invention relates to a receptacle for fluids and more particularly to such a receptacle adapted to contain fluids, such as petroleum products during transportation thereof.

A primary object of this invention is the provision of an'improved fluid containing receptacle provided with means whereby the same may be readily floated in a body of water, and towed as by a' boat to a desired destination, and so arranged and constructed that the same receptacle may be readily removed from the water and transported overland on a truck, a railway car, or the like.

A'iurther important object of this invention is the provision of an improved tank characterized by a baflle or shell of arcuate configuration closing oil a portion thereof, whereby the tank will float in an upright position, with a marked increase in stability.

An additional and important object of this invention is the provision of an improved tank provided with a protecting shield, whereby the tank may be let into the direct rays of the sun or the like, and the shield or dead air space will serve effectively to prevent too great a heat striking directly the contents of the tank.

A still further object is the provision of such a tank characterized by internal construction in such manner that the tank will float upright and level, and not as is customary in plain cylindrical tanks with one end or the other downwardly.

A still further specific object is the provision of a tank, of the character described, which when on land will right itself automatically when loaded.

A still further object is the provision of a tank characterized by the provision of buoyancy,insulating, and collision safe guard compartments on the ends and sides thereof, such-compartm'ent also providing additional dead air space.

Still another object is the provision of an improved cylindrical tank, provided with means whereby the interior braces or supports hitherto necessaryto maintain such a tank in proper structural relation may be substantially eliminated. a

A further object of the invention is the provision of a cylindrical tank, so arranged and constructed that the main body thereof may be maintained substantially full regardless of the temperature or other conditions affecting the volume of the liquid containedtherein.

A still further object of the invention is the provision of such a tank provided with a recess orspace into which the vapors or fumes of volatile fluids may escape, when the temperature of the liquid increases, and provided with means whereby the condensate of these vapors may be returned to the tank as the temperature, and the corresponding volume of th fluid in the tank decreases.

A further and more specific object of the invention is the provision of means in association with such a tank whereby the quantity of fluid introduced into'the same may be governed in accordance with the specific gravity f the liquid involved.

A further specific object is the provision of means in association with such a tank whereby the amount of liquid placed therein may be varied in accordance with the temperature of the liquid, and consequently its volume, in order to retain the tank substantially full at all times.

,An additional specific object is the provision of such a tank provided with an improved means permitting fluid to overflow into the vapor compartment on increase in temperature, and return to the tank on decrease in temperature.

Still another object of the invention is the provision of such a tank provided with means whereby a plurality of tanks may be secured together in related assembly to provide a tank train, which may be towed through a body of water.

Another and more specific object is the provision of means whereby such a tank may be readily secured to a land vehicle for transportation thereon.

Still other objects reside in such a tank which will be sturdy and durable in construction, reliable, buoyant, stable, and eflicient in operation, and relatively simple and inexpensive to manufacture and assemble.

Other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter and disclosed in the accompanying drawings wherein there is shown a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a side elevational view of one form of tank embodying thi inventive concept, certain concealed parts thereof being indicated by dotted lines.

Figure 2 is anenlarged sectional view taken substantially along the line 22 of Figure 1 as viewed inthe direction as indicated by the arrows.

Figure 3 is an enlarged vertical sectional view taken substantially along the center line of the device forgoverning a float valve controlling the aioasos 3 admission of fluid into the tank in accordance with the temperature and specific gravity of the fluid.

Figure 4 is a fragmentary, top plan view of a constructional detail of the device shown in Figure 3.

Figure 5 is an enlarged sectional view taken substantially along the eenmr line of the tank, and showing the compartment in which the control means and inlet valve are contained.

Figure 6 is a fragmentary detailed View showing one method of assembling a plurality of tanks into a tank train, and

Figure 7 is a fragmentary elevational view disclosing an additional constructional detail adapted to be utilized in conjunction with the tank, when the same forms the warmest tank of a tank train.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Having reference now to the drawings, there is generally indicated at In a cylindrical tank, closed at it's ends as by externally convex pressure head It. Positioned within the tank HI, and secured thereto in fluid tight relationship, as by welding or the like, is an arcuate shield or shell H, having a greater radius of curvature than the arc of a tank, and providing above the fl-uid containing base of the tank a vapor escape compartment of generally crescent shaped crosssectional configuration.

A recessed compartment |2 in the top wall of the tank 10 extends to the top of the shell I and is provided with a pair of spaced apertures, through which extend a valve fitting l3 and a control m'ember generally indicated as l4, both to be more fully described hereinafter.

The recess i2 is provided with a hinged cover iii adapted to be held in place as by a locking means it including a bolt and wing hut H, a suitable sealing gasket |8 being provided to retain the compartment |2 watertight when the tank is floated.

As best shown in Figure 2-, the shell I is provided with 'a centrally disposed aperture I9, from which a pipe 29 extends upwardly to the outer periphery of the tank 10, and thence curves in two divergent branches 2| to openings 22 positioned adjacent the juncture of the shell H with the side wall of the tank ill but spaced slightly therefrom, the arcuate member 2| closely conforming to the configuration of the top of the tank Hi. Flu-id diffusing baffles 2 3 are positioned interiorlyci the pipe 1 9.

Float valves -25 of conventional construction adapted to remain in closed position so long as the float thereof is immersed in fluid are positioned at the opposite extremities of the juncture of the shield with the tank I'll,

From the foregoing it will now be seen that when the tank E2 is filled completely in a manner to be more 'fully described hereinafter in such manner that the fluid obstructs the under surface of shield expansion of the fluid, a might be occasioned by an increase in temperature causes a certain quantity thereof to pass through the pipe 29 into the pipe 2| and thus into the vapor expansion chamber between the shield II and the upper surface of the tank H). As the temperature is reduced, a syphoni'ng effect may be produced by the tube 2| to withdraw the fluid into the body of the tank. The valves 25'are provided in order that when the tank is emptied, the lowering of the level of the fluid in the tank will occasion the opening of the valve, whereupon any fluid retained in the vapor chamber upon the shield will flow into the tank, and be withdrawn with the balance of the contents thereof.

Referring back to the valve I3, as best shown in Figure 5, it will be seen that the same comprises a fitting 2'! to which may be secured a flexible tube or the like for filling the receptacle, within which is positioned a valve seat member 28 adapted to be closed at its upper extremity by a valve 29, secured to a valve stem 30. The valve stem 39 is secured as by a pivot 3| to a rod 32, at the opposite extremity of which is positioned a float 33. The rod or lever 32 is fulcrumed at 34 to a rod 35 extending downwardly from the bottom of a casing 38 comprising a portion of the control member l4.

As best shown in Figure 3, the rod 35 is provided with a conventional swivel 31 of any desired type whereby the upper portion of the same may be rotated with respect to the lever 32, and extends upwardly through the casing |3 to the exterior of the shield H, and terminates in an operating handle 38. The upper portion of the rod 35 is threaded as at 39 and engages correspondi'ng interior threads on a sleeve 40 provided with an operating handle 4|. The exterior of the sleeve 48 is also threaded as at 42 and is adapted to engage interior threads 43 positioned interiorly of the housing 36.

A partition 44 extends interiorly within the housing 36, in close juxtaposition with the rod 35, beneath which are positioned packing glands or washers 45 held in position as by a packing r nut 45, the parts being held in related assembly as by an apertured cap 41 threadedly secured to the lower portion of the housing 36,

The upper portion of the casing 36, which as previously stated extends through a suitable aperture in the shield H, in fluid tight relationship therewith is provided with a peripheral flange 48 on the upper surface of which is a dial 49 marked with suitable indicia. Each of the operating handles 38 and 4| is provided with an aperture 59 and 5|, respectively, through which the indicia on the dial '49 may be viewed.

It may be here pointed out that the interior and exterior threads of the sleeve 40 are oppositely disposed, in such manner that the sleeve 40 may be rotated by the operating handle 4| independently of rotation of rod 35 by operating handle 38. That is to say, that rotation of the operating handle 4| will, through movement of the sleeve 40, vary the position of the float 33, and hence the adjustment of the valve 29 to a lesser degree than were rotation of the operating handle. Accordingly, the handle 38 may be set as may be desired until a desired numeral on the dowel 19 is visible through the aperture 50, such numeral indicating the temperature of the fluid, or the surrounding atmosphere, as previously determined, and the operating lever 4| correspondingly adjusted until a desired numeral on the dial '49 is visible through the aperture 5|, such numeral indicating the specific gravity of the fluid with which the tank is to be filled, After the setting has been obtained, which latter setting may be determined mathematically by means of charts or formulae or the like, the float valve is so arranged that the float 33 is positioned'to close the valve when the exact quantity of fluid in accordance with temperature and specific gravity been admitted into the tank ll] to f ll the has same'completely.

filled in the manner above described, the contents thereof are'maintained .substantially constant regardless of variations in'temperature by means of the overflow mechanism and float valves 25 previously described.

Additional buoyancy. and stability compartments extend entirely along the sides .of the tank, and are formed by arcuate bafiles 52 welded to the sides of the tank as indicated at 53,1to form elongated buoyancy chambers, which also serve as bumpers in the event of collision between the tank and other objects. Still further compartments are formed at each end of the tank as by means of exteriorly positioned baliles 54, similarly welded to the tank, and thus serve further to stabilize, float, and protect the tank.

As best shown in Figure 6, suitable lugs 55 are positioned at opposite sides of the pressure head I 0, between which are adapted to extend links 56 for connecting a series or a plurality of tanks in longitudinal alignment. lugs 51 positioned on the sides of the tanks, adjacent the extremities, are adapted to accommodate similar lugs 58 on opposite tanks to secure a plurality of tanks in transverse alignment. Similarly, lugs on the tops of the tanks 59 may accommodate transverse bars 88 to provide lateral stability of associated tanks.

Thus, it will be seen that a plurality of tanks may be assembled into a tanktrain, in any desired arrangement, a relatively Wide body of tanks being utilized, if desired, in a broad sheet of water, while'a single or double line might be more advantageously utilized in a relatively restricted stream.

The lugs are so arranged that, if desired, a rudder 6| (see Figure '7) may be positioned on the rearmost tank or tanks of the train to assist in steering the same. Similarly, the lugs 51 may be advantageously utilized for securing'the tanks to a vehicle, such as a truck or train when the same is removed from the water.

The tank is particularly designed to be utilized in conjunction with a transportation system, whereby the tank may be filled at the refinery or the like, and conveyed by any suitable means to a body of water, where a plurality of tanks may be assembled into a train and towed to a desired distribution point. As the distribution point is passed or approached, a selected quantity of tanks may be detached from the train, which then continues on its course, and the tanks towed to shore where they may be removed from the water by means of suitable tracked behicles or the like, and loaded upon trucks or freight cars for suitable further distribution. Obviously, the process may be repeated until all of the tanks of the shipment have been distributed as desired.

From the foregoing it will now be seen that there is herein provided an improved shipping tank for fluids, such particularly as fluid fuels, characterized particularly by stability when immersed in water, by constant volume of content, and by adaptability to land transportation with a minimum of difliculty, which accomplishes all the objects of this invention and others including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
