METAL SHIPPING BARREL Filed Dec. 31, 1934 "2 Sheets-Sheet 2 Z4 INVENTOR. I
2/ /1672? .5. Z/ieem Patented Feb. 7, 1939 UNITED STATES PATENT OFFICE 7 Claims.
The invention relates to metal barrels, drums, etc., particularly adapted for shipping and handling solids, and liquids.
The transportation of liquid in barrels or drums over any appreciable distances has heretofore been relatively expensive particularly to the shipper and carrier and thus ultimately to the consumer. Especially has this condition been prevalent in the oil industry, since in order to withi stand the rigors of shipping, the carriers and various governmental commissions, have made freight rulings which require the barrels or drums to be of relatively heavy gauge or thickness of material for different capacities and contents. A
15; particular disadvantage in the use of the type of barrels and drums at present in use, resides in the necessity of leaving the barrels with the customer or user until emptied. It will thus be clear that for long periods in the life of the barrel, it is 20 merely utilized for storage purposes or subject to handling in a manner out of all'proportion to the rough treatment to which it is exposed during shipment. On the one hand, therefore, a heavy duty barrel is required, and on the other hand a lightweight drum of simple and inexpensive construction is ample. Then too the heavy duty barrel or drum is extremely light for its bulk and therefore its reshipment as an empty is naturally quite unprofitable to the carrier.
With the foregoing in mind, I have aimed at providing a barrel or drum which could profitably and to a large extent be a one-time shipper, that is, a drum furnished and filled at the refinery and shipped to and kept permanently by the customer.
35 At the same time the drum when undergoing the process of shipping would have all of the elements of strength, safety, etc., required under the rulings, and any reshipment of parts would concern only the shipper and carrier and not result in any burden on either of them.
In carrying out the invention in its preferred form, I utilize: as one of the elements, a metal inner container in which the oil, liquid or other substance may be confined and sealed, and which is formed with walls of a relative light gauge and suitable material to permit of normal handling of the container and contents but not suflicient under the rulings aforesaid for shipping as of itself when filled. In order that the inner drum may be shipped with contents, I arrange for the removable positioning thereon, of a metal enclosing housing or jacket which is formed with walls of a gauge considerably heavier than that of the inner container and well within that required 55; by therulings. The enclosure or jacket, being,
readily positionable on or removable from the container, is placed on the container before the latter is filled and is thereafter not removed until the container is shipped to its destination, when the carrier retains the jacket and delivers the 5 container to the customer. By reason of the fact that the jacket is made in sections which may be readily nested one within the other, return of the jacket to the shipper, particularly in num-- bers, will be a matter of small expense to the ship- 10 per and profitable to the carrier. It will thus be seen that while the inner container or drum is designed for a single shipment, the protecting jacket owing to its relatively sturdy construction, may be used over and over indefinitely and at no time need the shipper carry a supply of such jackets in excess of what is required for actual shipping.
The invention has aims and features in addition to those brought out'in the foregoing, and such additional aims and objects will be set forth in the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of the specification. It isto be understood, however, that variations in the showing made by the said drawings and description may be adopted within the scope of the invention as set forth in the claims. 1
Referring to said drawings:

In the embodiment of the invention illustrated in the drawings, the shipping unit comprises three main parts, to wit, an inner container Ill, and a protective jacket H composed of a pair of sections l2 and [3. The container or drum II] is formed with end. walls I4 and cylindrical side walls l6 connected at their edges by a double seam joint I! which is reeniorced by a chime angle ring [8. On one of the end walls M there is provided an opening fitting l9 through which the container may be filled or its contents emptied. A plug 2| is shown for closing the opening. If desired the end walls may be formed with offset portions 22 so as to increase the resistance of said walls to flexure and also to permit a limited amount of radial expansion or contraction of the wall without undue strain on the joint ll. Both the end and side walls of the drum are formed of sheet metal of as light a gauge as possible to afford the container the strength and rigidity necessary to insure safe handling under normal conditions and particularly while the drum is full. To facilitate the rolling of the drum when removed from the jacket, a pair of spaced outwardly extending annular beads 23 is formed in the middle portion of the walls I6, and such beads in cooperation with corrugations 24 formed between the beads and the ends of the walls, serve to materially strengthen the drum against sidewise collapse or distention.
The sections l2 and I3 comprising the shipping protective jacket for the drum, are here shown as like semi-cylindrical segments of such size and form as capable of completely enclosing the sides of the drum when the sections are applied thereto in circumferential and transverse alignment. The walls of the sections as will be clear from the drawings, are formed of sheet metal of a gauge much heavier than that of the container walls, and as before explained, the thickness of the metal is such as to be well within the requirements stipulated by the regulatory powers to permit shipping of drums with various contents. It is important to note that in the preferred embodiment of the invention the jacket is designed to forcibly embrace the side walls of the drum so that not only will the drum be firmly held in position, but both walls, that is of the drum and jacket, will combine and reinforce each other in withstanding forces applied to them. Furthermore the tension set up between the drum and jacket by reason of the embrace of the latter, is of a resilient nature so that the embracing relation may be maintained notwithstanding deformations in the members and without undue strains being imposed on the members. Resiliency in the engagement of the jacket and drum walls is afforded largely by reason of the engagement of the jacket walls with the outer peripheries of the corrugations in the drum walls; the latter owing to its relative thinness permits a certain fiexure particularly at such corrugations.
In order that the jacket sections may engage or embrace the drum walls over practically the entire surface thereof, the jacket sections are formed with annular outwardly extending depressions 26 in which the rolling beads 23 of the drum may seat when the sections are operatively disposed on the drum. By reason of the depressions 25 there is provided on the exterior of the sections corresponding annular beads 2! on which the unit may be rolled when necessary. The positioning of the beads 23 in the depressions 26 also serves when the former have contact with sides of the depressions to hold the inner and outer members from relative longitudinal displacement in opposite directions. Holding of the container within the sections against displacement is also afforded by means of beads 28 extending inwardly from the longitudinal ends of the sections and designed to overlie and engage the ends of the container. As here shown the beads 28 are designed to contact with a protective plate or reenforcement 29 covering the end of the container. Preferably the portion of the plate contacted by the bead bears directly on the chime ring I8 so that the container will be firmly confined between the beads at the opposite ends. It will be clear that with the beads 28 engaging the container, efiective retention of the container against longitudinal displacement in the jacket may be had even though the rolling beads 23 are out of contact with the sides of depressions 26, it being noted that under some circumstances in order to insure better resilient engagement between the container and jacket, said beads 26 are formed to avoid actual contact with the jacket.
Where the end walls M of the container are formed of relatively heavy material, the plate 29 or other form of reenforcement may be dispensed with, but in most instances it is desirable that a member similar in form and size to the plate be provided to afford a convenient surface for the representation of identifying matter of one kind or another. In any case where the plate is used, an opening iii 55 preferably formed therein so as to avoid interference with the use of the bung opening and the positioning of the closure plug 2i therein. It is important to note that while the portion of the fitting l9 on the exposed side of the container end wall is within the longitudinal confines of the chime ring, the closure plug is usually of necessity left to extend beyond the ring. When the plug is so positioned, it is, in the unit of my invention, still protected since the beads 28 are designed to extend well beyond the outermost point of the plug. Another important advantage in the use of the beads 28 is that they serve to reenforce the sections to a degree rendering the mutilation or deformation of the sections practically impossible even under the abuse to which they are subject in shipping, either in operative position about the container or in disassociation therefrom, it being understood that the portion of the sections usually most subject to deformation is at the ends.
Near each of the ends of the jacket sections are also provided annular outwardly offset portions 32 which provide a three-fold advantage for the structure. In the first place such offset appre ciably reenforces the sections; in the second place the inner container walls are aiforded greater security from damage by any inward buckling of the jacket walls; and in the third place, by reason of the greater expansibility of this portion of the jacket and the provision of a space therebetween and the portion of the container side walls at the periphery of the end walls, any folding or pinching of such container portion, as usually occurs when the unit is dropped on end, may take place without the crushing force of the jacket being directed against the folds so as to cause the cracking of the metal at the creases. Desirably the oifsets 32, while located near the ends of the jacket walls, are located sufficiently inwardly of the beads 28 to permit a portion of said walls to bear against the chime ring.
Since in the present embodiment of the invention, the jacket sections are designed to perrnit complete detachment of the sections from each other as well as from the container, means are provided on the sections for the guiding of the" sectionsinto proper alignment with each other when moved into: place about the container for operative positioning thereon. Such a means is here shown as a. part of the beads 28 at the ends-of thesections. By reference particularly to Figure 3, it will be seen that fromone endof each of the beads 28 there extends a stud 33 which is anchored Within the bead and is arranged for insertion in the free end of the adjacent bead of the complementary section. With this arrangement, by thus entering and moving the studs into the beads, the sections will of necessity be moved into proper alignment, both circumferentially and transversely.
Additional means for guiding the sections together in operative alignment is provided at a plurality of intermediate points along the longitudinal edges of the sections, such means being desirably associated with means for locking the sections together in operative and embraced relation about the container. Both means are preferably carried at each of said points, on plates 36 and 37, one plate being afiixed to one section while the other is affixed to the other section. On one of the plates, here shown on plate 36, is secured a stud 38 positioned so as to enter an opening 39 in the plate 3'! in substantially the same manner and at the same time that the stud 33 moves into the bead. For locking the sections together there is provided a lever 4! which is here shown pivoted to the plate 35 and formed with a hook end 42 designed for releaseable engagement with a shoulder 43 on the plate 37. The lever has ample bearing surfaces M on each side in both plates and therefore when the lever is hooked in position any force tending to buckle the jacket inwardly along the adjacent edges of the sections will be effectively resisted by the lever, as well as by the studs 33 and 38 and the engaged parts. In order that the lever may be locked in engaged position, a sealing pin ti may be inserted in registered openings 48 and B9 in the lever and plate 31 respectively. To break such seal and release the lever, a blow is struck against a protuberance 5! on the lever so as to shear the pin.
It will be understood that in, assembling the jacket sections on the container, the former are held against the container with considerable pressure applied from an extraneous force, and
in order that the sections will remain forcibly embraced with the container, the levers. are hooked in position while the sections are so held and the relationship of the levers and shoulders are such that no appreciable distention of the sections may occur after the said extraneous force is removed. If desired, a small space may be left between the adjacent edges of the sections and of the plates so that the tensional embrace of the container by the jackets will be assured. Also if desired,'th-e container may be fully or partly covered with a wrapping of paper or other material for the purpose of insulating or otherwise protecting the container or its contents. As shown in Figure 8, the side walls of the container are covered with a sheet 52 of paper or the like, While a sheet 53 of similar material is fitted over the end wall of the container and provided with a slitted or other rim 5% which overlies the adjacent end of the sheet 53. Preferably the sheets 52 and 53 are thin and flexible so that they may be provided on the container without interfering with the proper engagement and embrace of the jacket with the container.
As before explained, the jackets are designed to be removed from the containers when the con tents are delivered to the customer, andthereupon reshipped to the refinery or other point where the jackets are to be re--used or assembled. In this con'nection it is important to note that the sections of the dismembered jackets may be readily nested one within the other as for example indicated in Figure '7, and in this state placed and retained on the carrier during reshipment. Thus the otherwise bulky and relatively light structure is shipped in compact form advantageous for shipping both to the shipper and carrier.
