Patented Mar. 24, 1953 UNITED STATES PATENT OFFICE 8 Claims.

The present invention relates to containers. From a more specific aspect, the invention relates to fluid-storage-and-transporting containers, such as metal oil tanks that are commonly mounted upon trucks.

According to present-day methods of manufacture, tanks of the above-described character are constructed by curving a continuous sheet of metal into cylindrical form of oval cross-section, and then welding the ends of the sheet to correspondingly oval-shaped vertically disposed horizontally alined end walls, the major axes of which are disposed horizontally. In order to permit of access to the man-hole domes disposed at the top of the tank between longitudinally disposed upward projecting flashings, longitudinally disposed platform treads or walks are provided, on along each side of the tank, projecting horizontally outward substantially in or slightly below the plane of the major axes. The flashings and the platforms are secured to the cylindrical wall of the tank by welding operations that raise unsightly lumps at the exterior junctions between the cylindrical wall, on the one hand, and the flashings and the platforms, on the other. It then becomes necessary to eliminate these unsightly lumps by grinding and this grinding is tedious and expensive.

An object of the present invention is to provide a new and improved tank or other fluidstorage container.

Other and further objectswill be explained more fully hereinafter, and will be more particularly pointed out in the appended claims.

e The invention will now be more fully explained in connection with the accompanying drawings, in which Fig. 1 is a perspective of an oil tank embodying the present invention, looking from the rear of the tank; Fig. 2 is a vertical longitudinal section taken upon the line 2-2 of Fig. 4, looking in the direction of the arrows; Fig. 3 is a perspective of the man-hole structure shown in the tank of Fig 1; Fig. 4 is a perspective similar to Fig. l, with parts broken away, showing the tank partly completed; Fig. 5 is a fragmentary perspective of a metal plate for assembly with the partly completed tank shown in Fig. 4 to provide a lower wall for the rear compartment of the tank; Figs. 6, '7 and 8 are perspectives of properly shaped metal sheets for similar assembly with the partly completed tank shown in Fig. 4 toprovide rear and front lower depending flanges and an upper tank wall, respectively; Fig. 9 is a fragmentary elevation, upon a larger scale, of a modified drain for the tank; Fig. 10 is a vertical section taken upon the line Illof Fig. 9, looking in the direction of the arrows; Fig. 11 is a fragmentary elevation similar to Fig. 9 of a further modification; Fig. 12 is a vertical section taken upon the line I2--I Z of Fig. 11, looking in the direction of the arrows; Fig. 13 is a 'vertical transverse section taken upon the line I3I3 of Fig. 1, looking in the direction of the arrows, but upon a larger scale; Fig. 14 is a perspective similar to Fig. 8 of a modification; Figs. 15 and 16 are similar perspective of parts for attachment to the rear and the front, respectively, of the part shown in Fig. 14; Fig. 17 is a similar perspective of a depending-flange modification for attachment to the part shown in Fig. 8; Fig. 18 is an elevation of a truck, with the tank of the present invention mounted thereon; Fig. 19 is a fragmentary elevation of the same, upon a larger scale, partly in longitudinal section; and Figures 20 and 21 are perspectives of details of parts of the housing at the rear of the tank.

Metal tanks of the type illustrated herein are of oval shape, with the major axis of theoval horizontally disposed, The front and the rear sheet-metal end walls I6 and I8 are therefore shown of this oval shape, with their bottoms and tops and their adjacently disposed regions each increasing in width from its top and its bottom toward the center. Additional intermediately disposed similarly shaped sheet-metal walls may also be provided if it is desired to divide the tank into separate compartments for containing different oil fuels. One such additional wall is shown at I1, thus dividing the tank into two compartments, a front compartment between the walls I6 and I1, and a rear compartment between the walls I! and I8.

An upper sheet-metal side wall I, curved to conform to the upper portion of the oval-shaped walls I6, I1 and I8, may be secured to these walls at one side thereof, as shown in Figs. 1 and 13, by welding to the upper portions of bent-over flange margins I9, 20 and 2 I, respectively, of the walls I6, I1 and. I8. A similar upper sheet-metal side wall 5 may similarly be secured to these walls I6, I! and I8 at the other side thereof, as shown in Figures 1, 4 and 13. The front edge 34 of the wall I is welded to the flange I9, its rear edge 33 to the flange 2|, and an intermediately disposed portion of the wall 34 to the flange 20.

The wall 5 is similarly secured. The lower portion of the wall I terminates in a horizontally disposed ledge 3I, and the lower portion of the Wall 5 in a similar ledge 50. As shown clearly in Fig. 13, the ledges BI and extend outwardly 3 in a common horizontal plane, just below the major axis of the oval-shaped walls I6, I! and I 8.

The upper portion of the wall I terminates in a vertically upstanding wall 29, and the upper portion of the wall 5 in a similar wall 39 parallel to the wall 29. The

walls

29 and 39 are longitudinally disposed, one on each side of two manholes 4, one for each compartment of the tank.

The upper walls I and 5 of the tank, therefore, form coverings for the major portion of the upper part of the tank. Their lower portions, as already explained, terminate just below the horizontal major axes of the ovals, and a longitudinally disposed gap is formed between their upper portions.

In order to cover the remaining portion of the upper part of the tank, this gap is filled by a man-hole structure comprising a sheet-metal top-wall plate 2 provided with the man-hole openings 4 and curved to conform to the upper portions of the oval-shaped walls I6,II and I8. This plate 2 is welded to the upper portions of the walls I6, I! and I8. Along its longitudinal edges 35 and 36, as shown at 8i and 82, it is welded also to the upper walls 5 and I, respectively, at their junctions with their respective The man-holes 4 are constituted of metal cylinders welded at 83 in corresponding openings of the plate 2. They may be closed by means of suitable man-hole domes, not shown.

The lower covering of the tank is constituted of a suitably curved sheet-metal bottom wall I welded to the lower portions of the flanges I 9, and 2| of the walls I6, I1 and I8. The front margin of the lower wall I5, for example, is shown welded at I2 to the inner edge of the lower portion of the flange I9. The front edge of the lower wall I5 is similarly shown welded at 13 to the peripheral edge of the wall IS. The upper side edges of the wall I5 are interiorly welded at I9 and 80, respectively, to the upper walls 5 and I, the former at its junction with its horizontally disposed ledge 50, and the latter at its junction with its horizontally disposed ledge 3I. A further line of exterior weld I1 is provided between one of the upper side edges of the wall I5 and the underside of the ledge 50, at its junction with the lower side edge of the upper wall 5, and a further similar line of exterior weld I8 is provided between the other upper side edge of the wall I5 and the underside of the ledge 3i, at its junction with the lower side edge of the upper wall I.

Sills 26 and 21 for supporting the tank on a truck 81 are welded at I4 at the lower exterior surface of the wall I5. The tank may be secured to the truck by means of bolts I02 passing through bed supports IIII of the tank and cooperating with nuts I04 and washers I93.

The ledge 3I is provided with a terminal depending lip 32, and the ledge 59 with a similar lip 5I. A lip 38 at the free end of a ledge 37 of a front depending flange or skirt I2 is welded at 85 to the front portion of the lip 32, with the ledge 3'! in the same horizontal plane as the ledge 3|. A similar alined lip at the free end of a ledge 40 of a rear depending flange or skirt I3 is similarly welded at 85 to the rear portion of the lip 32, with the ledge 40 in the same horizontal plane as the ledge 3|. A horizontal longitudinally disposed platform tread or walk II is then welded at 86 to the exterior of the wall I at its junction with the ledge 3| and to terminally upstanding alined lips 9I at the upper ends of the depending flanges I2 and I3, at their junctions with the

respective ledges

31 and 40. The rear edge 43 of the front depending flange I2 is welded to the front edge 44 of the rear depending flange I3.

Another horizontally disposed platform tread or walk II is similarly provided along the other side of the tank. Two depending front and rear flanges or skirts are also provided, identical in construction with the front and rear flanges or skirts I2 and I3, except that they are the mirror images thereof. The rear depending flange or skirt 52 only is illustrated, provided with the ledge 53 and the upper lip I4, welded at 84 to the lip 5|. The said other tread II is shown welded at 96 to the exterior junction between the upper wall 5 and the ledge 50, and also to the lip I4.

If desired, the depending flanges I2 and I3 may be replaced by a single depending flange 68, having a ledge 69 and a lip III to correspond to the

ledges

31 and 40 and the lip 38. The depending flanges I2 and I3 are provided with an inwardly extending lip 39, the depending flange 52 with a similar lip 55, and the depending flange 68 with a similar lip II.

The front portions of the front depending flange I2 and its non-illustrated counterpart are curved forward, as shown at 4I. The rear portions of the rear depending flanges I3 and 52 are similarly curved rearward, as shown at 42. A rear wall 5 is welded along curved edges 92 to the rear edges 33 of the walls I and 5. Bent-in flanges 93 of the rear wall 5 are welded at corresponding bent-in flanges 94 of the portion 42. The upper portion of the rear wall 6 is provided with an upwardly curved tongue 99, the forward edge of which is welded to the rear edge 89 of the plate 2, and to a metal plate I95, Fig. 19. A bumper It is welded along edges 98 to edges 91 of the rear wall 6. Edges 99 of the bumper III are welded to edges 98 of the rear Wall 6 and to the curved portions 42. A housing is thus provided at the rear of the tank, the floor of which is constituted of a plate 28, shown supported at I05, to provide a bottom wall for the housing. The portions 22 constitute integral rearward extending end walls of the flanges I3 and 52 to constitute end walls of the housing. Access to the interior of the housing may be had by raising a door I about hinges 8 by means of a handle 9. When closed, the door I engages a flange of the bumper I 0.

The curved plate I5 is shown integrally provided with two

troughs

22 and 24, the former of which extends inward from the rear end through the rear compartment, between the walls I! and it, into the front compartment, between the walls I6 and I1, and the latter of which extends similarly into the rear compartment. A plate 23 is welded to the inner face of the curved plate I5, as at 15 and 75, over the trough 22, so as to prevent the contents of the rear compartment from entering the trough 22. Ihe trough 22, therefore, provides communication between the front compartment only and the outside atmosphere, and the trough 2 with the rear compartment only. If more than two compartments should be provided through the addition of further inter? "mediately disposed walls. ll, similar plates 23 would be similarly welded over theportions of the corresponding troughs that would extend through each compartment except. the compartment or compartments into which the inner end ofthe corresponding trough terminates.

Fluid may be dispensed from the respective compartments by making suitable hose connections to the

troughs

22 and 24 through drain connections 25, shown as externally threaded nipples. The oil is delivered from the drain connections.- 25. through a manifold and valves (not shown). i

According to the modification illustrated in Fig. 14., the upper curved wall. 56 is identical with theupper curved wall I, the upstanding vertical wall 60 corresponding to the upstanding vertical wall 29 and the rear edge 6| to the rear edge 33. The ledge 3|, however, is replaced by a platform tread or wall 51 of twice its width, and it is made integral with the depending flange or skirt 58 and the lip 59, which takes the place of the two depending flanges l2 and I3 and the lip 39:. The front edge 63 of the depending flange is welded to the rear edge 61 of a separate front curved wall 66, and its rear edge $2 is welded to the front edge 65 of a separate rear curved wall 64.

The

curved walls

66 and 64 may be employed also with the depending flanges I2 and I3 and also with themodification of Fig. 1'7, according to which the depending flanges l2 and I3 are replace-d by a single flange or skirt 68 having a front edge 63, a rear edge 62, and a platform tread or walk 69.

Further modifications will occur to persons skilled in the art, and all such are considered to fal1 within the spirit and scope of the invention, as defined in the appended claims.
