1 Claim. 1

' This invention relates to a container and more particularly to a container for holding corrosive fluids or the like.

The primary object of the invention is to facilitate the shipping and handling of fluids under pressure and more particularly fluids of a corrosive nature which are likely to injure or destroy the material from which the container is made.

Another object is to protect against such injury the container and at the same time to avoid contamination of the contents thereof through contact with the main body portion of the container.

Among its features the invention embodies a container of ferrous metal, such as steel having a heavy coating of nickel or other corrosive resistant substance on the interior thereof, which coating is of a thickness at least equal to onefourth 'of the thickness of the metal from which the container is constructed.

Other features employ composite welds in joining the parts of the container together so that the portions of the welds which contact the contents of the container will be formed of the corrosive resistance substance.

Still other features include equipping the container at one end with a valve housing or chamber which is disposed within the confines of the container, and a removable cover closing the open end of the valve chamber efiectively to protect the valves in said chamber from damage or being tampered with.

In the drawings:

Figure 1' is a fragmentary side view of a con tainer embodying the features of this invention, certain portions thereof being shown in section more'clearly to illustrate certain details of construction,

Figure 2 is an end view of the container,

Figure 3 is a sectional view taken substantially along the line 3-3 of Figurel,

Figure 4 is an enlarged detailed view of the locking boss by which the cover plate of the container is held in place,

Figure 5 is a fragmentary side view of a. modified form of container, certain portions thereof being shown in section more clearly to illustrate certain details of construction,

Figure 6 is an end view of the container illustrated in Figure 5, and

Figure 7 is an enlarged detailed view of the locking means for the cover of the modified form of container.

Referring to the drawings in detail this improved container designated generally 10 comprises a hollow cylindrical body l2 which is preferably formed of ferrous metal such as steel. This body is relatively thin and is equipped on its inner side with a layer or coating of nickel or other corrosive resistant material M which is of a thickness at least equal to one-fourth of the thickness of the body l2. Carried at one end of the body I2 is a head It of steel or like ferrous metal which is preferably of considerably greater thickness than the thickness of the body l2 and carries on its inner surface a coating [8 of corrosive resistant substance such as nickel which is of a thickness substantially equal to the thickness of the coating M on the body H2. The head 16 is concave-convex in form and its convex side is disposed outwardly. The junction of the body 12 with the head 16 is formed by a weld 20 such as is commonly employed in joining ferrous metals together, and joining the lining or coatings I4 and I8 is a weld 22 of nickel or other corrosive resistant metal.

Carried at the end of the tubular body [2 remote from the head I6 is a concavo-convex head 24 of a thickness substantially equal to the head l6 and carried on the concave side of the head 24 is a lining or coating 26 of corrosive resistant substance such as nickel which is of a thickness substantially equal to the thickness of the coating [4 on the body l2. Like the junction of the head IS with the body l2, the junction of the head 24 with the body 12 is effected by a conventional weld 23 such as is commonly employed in joining ferrous metals, and a weld 30 of corrosive resistant substance joins the linings l4 and 26 so as to form a complete corrosion resistant lining for the container. Formed axially in the head 24 is a relatively large opening 32 for the reception of a relatively thin concavoconvex closing head to be more fully hereinafter described. The closing head designated generally 34 comprises a concave-convex end member 33 provided with an annularflange 38 which fits in the opening 32 as will be readily understood upon reference to Figure 1. The concavoconvex body 36 and the flange 38 thereof are formed of a ferrous metal such as steel and is of a thickness substantially equal to the thickness of the body [2 previously referred to. A layer or coating of lining material 40, such as nickel is carried on the convex side of the body 36 and extends around the periphery of the fiange38 to form a complete protective coating for the body 36. This coating 40 is of a thickness substantially equal to the thickness of the coating I4, and the flange 38 is passed through the opening 82 and is joined to the head 24 by a conventional weld 42 While the coatings 26 and 30 are joined by an annular weld M of nickel or other material which will resist corrosion. The body at and the coating 4:; thereon are formed with aligning openings 46 in which is received the tubular shank 4-3 of a nipple 50 which is preferably formed of nickel or other corrosion resisting material and carries intermediate its ends an annular flange 52 forming a shoulder'54 which bears against the coating 40 and is welded thereto as at 56 by a weld of corrosion resisting material, such as nickel. Welded as at "58 to each nipple it is an eduction pipe 60 having its end disposed adjacent the body 12 in the immediate vicinity of the weld 30 which joins the lining i l with the lining 26. These pipes are also formed of a corrosion resisting material such as nickel so as to avoid contamination of the contents of the container during-storageand transportation therein. The portions of the members it of the nipples M which extend through the openings 45 are joined to the body 35 by conventional welds .62, and threaded into the cylindrical extensions 43 are valves 64 which are housed within the valve chamber 56 formed by the head 34 within the confines of the con tainer.

Carried by the flange '38 on the head 34 are peripherally spaced inwardly extending lugs =58 which are diametrically opposed and form .stops against which the peripheral-edge of a concaveconvex cover plate t engages. Carried by the flange 3t midway between the lug -68 is an inwardly extending lug l2 and .fixed to the inner side of the cover plate '5'!) is a hook shaped retainer M which is adapted to enga e behind the lug 12 to aidin holding the plate it against the lugs 6%. An angularly extend ng inwardly projecting lu ilfi is carried by the flange 38 diametrically opposite the lug 12 and is formed with an internally screw threaded open ng 82 for the reception of a cap screw '84 which projects through an openinril formed ad acent the edge of the plate it diametrically opposite the hook shaped retainer M. Drain=openin-s 88 are formed at spaced points in the cover 10 for draining moisture which may result from condensation within the chamber 6.6.

In the modified form of the invention illus-- trated in Figure 5, the container desi nated generally 90 comprises a tubular body 92 to opposite ends of which are welded .heads to form a completely closed container. The head 94 is joined to body 9.93 by a conventional weld Q5 and is formed with an axial opening 98 in which a relatively th n head 1.00 is supported by a conventional weld 1.9.2. .It is to be .noted that the head 9c is of considerably greater thickness than the body .92 and that the head I00 isrof a thickness substantially equal to the thickness of the body 92. Asillustrated, the head I00 issubstantially concavo-convex in form and is provided at its periphery with an annular flange [M which fits within the opening .98. Formed in the head adjacent the longitudinal axis of the container are spaced internally screw threaded openings Hit; in which valves P8 are threaded. Welded as at lit to the'head we and in surrounding relation with the open ngs Hi6 are nipples H2 which project into the container and support at their inner ends eduction pipes H4 which communicate with the interior .of the nipplesand are welded to said nipples as at U6.

i. place.

The ends I it of the eduction pipes I [4 are turned outwardly toward the body 92 and their ends I 18 are disposed adjacent the body 92 in the immediate vicinity of the weld 96.

Carried by the flange 1M and extending into the valve chamber I20 formed within the head Hlii are circumferentially spaced lugs I22 each of which is provided with a relatively narrow overhanging lip I24 for engagement with a flange 1Z6 carried at the periphery :of i a cover plate 128 which forms an end closure for the valve chamber I20. The flange I26 is provided with peripherally spaced notches 136 of a width sufiicient to receive the overhanging lips iz i of the lugs I22.

Carried by the flange its of the body tilt and ex- 'tendinginwardly of the chamber between the lugs .422 is alug 132 having an overhanging lip ltd which corresponds to the lips 12 i previously described except that it is formed with an in-- ternally screw threaded opening 536 for the reception of the threaded shank-of a cap screw i313 which when the cover M28 is in position in closing relation with the valve chamber 12c engages the flange ['26 to effectively hold the cover in Like the cover it previously described, the cover 128 is formed with drain openings me through which'moisture may escape from the interior .of the chamber 120.

In use when it is desired to ship or store .corrosive substances, the container illustrated in Flames 1 through 4 inclusive is .employedand it will be obvious that the substance to be shipped or stored may be introduced into the container through the valves 6d, nipples 5t and pipes :68

-- so as to avoid contact with any material other than the corrosive resistant lining of the container. Obviously contamination of the contents of the container will-thus be overcome and any damae to the body of the container It by 7 contact with :the corrosive substance will be avoided. It is obvious that the contents of the container may be drained by so positioning the container that the-eduction pipes will extend vertically while the container lies on its side. In the preferred form \of the invention both containers iii and 99 are equipped at opposite ends with bands I42 which extend beyond the convex ends 'of the container and are provided at their ends remote from the container with inturned flanges M4 which not only serve to protect the heads of the containers but also as handling means-by which the containers may be suspended by suitable grappling means. In the preferred form, the bands hi2 are provided at spaced 'intervals with drainage-openings i 46 to'prevent the accumulation of moistures between the heads the flanges I44.

Obviously the ,inturned flanges Mi on thebands M2 not only protect the ends of the container'but afiord level bases upon which the container may rest-whenin an upright position. They also provide means by which a grabhoolror a hold down hook may be connected to the container during loading and transportation. They also serve as means by which skids or shoesmay be connected to the container. If so desired the heads 38, S4 and W8 may be provided with bushings 550 having internally screw threaded openings for the reception of plugs which are provided withaxial openings containing-a substance which will melt when subjected' to a temperature which exceeds a predetermined value. It is evident that should ,suiiicient internal pressure be created within either the container it or the container 9i} itheiheads v30 or IBG will flex even to the point of reversing their contour and thus avoid the bursting or" the containers.

While in the foregoing ther has been shown and described the preferred form of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

I claim:

A container comprising a relatively thin elongated hollow cylindrical body, a relatively thick concave-convex head carried by and closing each end of said body, one of said heads having a relatively large central opening, a relatively thin auxiliary concave-convex head closing said opening with its convex side inwardly disposed and forming a valve chamber wholly within the container, said auxiliary head having a discharge port opening through the same, a pipe within the container leading from said port and extending angularly to a point adjacent the junction of said body with the said one head, a valve within the valve chamher and connected with said port to control the discharge of the content of the container from the pipe, circumferentially spaced lugs carried by said auxiliary head and projecting into the 6 valve chamber, a concave-convex cover closing said valve chamber with its convex side outwardly disposed and its curvature conforming to that of said one head, and a flange at the periphery of the cover for engagement with the lugs and having spaced notches extending through its periphery for receiving said lugs and to allow said flange to be turned into and out of engagement therewith during the mounting and demounting of the cover on the container.
