3 Claims.

This invention relates to a cylindrical container having a plywood body with metallic reinforcing bands at opposite ends, and possibly elsewhere. Such a container is adapted for the reception of solids, semi-solids or liquids. It

may be made in varying sizes and, to a certain extent, of dilerent materials, although I prefer plywood for the body and iron or steel for the reinforcing bands.

It is a primary object of this invention to provide a container of the kind indicated which may be produced expeditiously, with a minimum of expense, and with a maximum of strength. In addition, it is desired that the container so formed vl5 should be tight against leakage, and strong to withstand hard usage encountered in service.

In the accompanying drawings are set forth an exemplification of my invention in the manner following:

20 Figure 1 is a View in plan of a plywood panel with bands attached preparatory to the bending operation;

Fig. 2 is an end elevation of the plywood panel with band attached, passing through -a moistener 25 by which water is applied to one face of the panel;

Fig. 3 is an end elevation of the plywood panel with attached bands formed into a shell, as when the bending operation is concluded;

Fig. 4 is a side elevation of the shell showing -a connection of staples applied to the overlapped edges of the panel. In this figure is also illustrated a spot weld connection, applied in a subsequent operation, between the overlapped ends 35 of the bands at the ends of the shell;

' Fig. 5 which is a similar view illustrates a further connection between the band ends, applied in an operation subsequent to forming of the shell;

Fig. 6 is a fragmentary vertical section through the end of the cylindrical shell showing a head fitted thereto and secured in place by an inward crimping or bending of the free edge of the reinforcing band;

Fig. 7 which is A`a similar view shows a like assembly of parts in which the free edge of the band is rolled inwardly to secure the head in place;

Fig. 8 which is a similar view shows tongues 50 attached to the band for securing the head in place, one of the tongues being ln a preliminary position and another in a nal position;

Fig. 9 which is a similar View shows a modified construction of cylindrical shell in which the 55 applied bands are arranged flush with'the shell ends, the heads being inset therewithin; and

Fig. 10 which is a View similar to Fig. 4 shows a modiiie-d construction in which the shell edges are connected in butt joint relation.

For the present container I use a body A which is formed from a rectangular panel p, preferably of plywood. The grains of the several plies are desirably arranged transversely of each other so that, when bent into the form of a cylinder, the grain of the outermost ply will extend circumferentially. The opposite ends of the panel are designated as 9 9, and the opposite side edges are designated as Ill-I0.

Att-ached to each of the panel ends is a striplike band B, desirably of metal or plywood. The length of each band is approximately that of the panel end. The arrangement is such that an edge and end of the band will extend freely beyond the corresponding end 9 and edge IB of the board. To secure each band to the panel I may employ staples II applied with the aid of a machine designed for such purpose. When affixed to the panel in the manner described, each band will present a free edge I2 beyond the end 9 of the panel and a free end I3 beyond the edge I0 of the panel.

The iiat panel with its band face down may then be passed between upper and lower rails I4 and I5, respectively, the latter being felt-covered and revolving in a bath E6 of water, glue, dye or other liquid whereby the moving panel is moistened on its under face only. Next the panel is bent into the form of a cylindrical shell with the bands lying upon the exterior thereof the face of which optionally is moistened by the operation just described. This bending may be performed conveniently with a revolving cyllnder and without the aid of heat or steam. When concluded, the panel edges Il! will be overlapped, as Shown in Fig. 3, suiciently to cooperate with staples I'I driven therethrough to establish a permanent connection. This stapling operation may be performed before the shell is removed in its entirety from the forming cylinder. The staples extend at close intervals in a line between the two circumferential b-ands at opposite ends of the shell.

The succeeding operations include irst, a securing of the overlapped ends of the bands adjacent their free edges beyond the shell ends, and, second, the securing of the overlapped ends of the bands at points inside the ends of the shell. veniently be accomplished by a spot weld, as indicated at I8 in Figs. 4 and 5. The further se- The first of these operations may con' curement of the overlapped ends of the bands inside the shell may be accomplished by additional staples IS which are driven through the shell body as well. Either of these two securement operations may precede the other. From the foregoing it will be apparent that the staples Il and I9 secure thelower or inner lap of the steel bands together and to the shell, while the spot weld performs the function of integrally uniting the outer unsupported lap of the bands so that this portion of the band will function as a relatively stiff one-piece, unbroken band which` is quite essential, after the outer lap of the band has been crimped down on the top of the head, in preventing upward springing of the head, all as will be more fully explained hereinafter.

The construction provided by these operations is complet-e except for the heads. Each shell end terminates inside of the outermost free edge of the proximate band and so provides in conjunction therewith an annular seat adapted to receive a Circular head H. rI'he head, when fitted in this position, is then secured fixedly in place. For this purpose use is made of the band itself in any of several different ways three of which are sug-l gested in Figs. 6, 7., and 8.

According to Fig. kt, the extended or free portion of the band may be inwardly bent or crimped as at 2) to lie fiat, or substantially so, against the outer face of the head. In this case, the strength of the band material is relied upon to hold the head securely in place without additional locking means.

According to Fig. 7, the free portion of the band is rolled inwardly into a bead, if desired, as at 2|. When so bent in, the roll or bead will engage the outer face of the head to secure it flxedly in place.

, In Fig. 8 I have shown the free edge of the band as folded back upon itself at V22. 'I'his provides an edge which is reinforced and also sufficiently rounded to avoid injury to objects with which it may come in contact. Through this band is formed a plurality of slots 23, each of which may accommodate an eye 24 at, one end of a tongue 25 from which` are struck prongs 26. In a. preliminary position the tongue appears as shown at the right hand side of Fig. 8. When the tongue is swung down flat upon the head, as indicated at the left hand side of Fig. 8, the prongs ,are driven into the head. When so positioned, the tongue which extends through the slot in the strip is effective to hold the container headv in place.

The preceding description has been concerned with shells having attached bands of metal which extend in part beyond the chime. My present invention is applicable as well to shells in which the bands, made of metal or plywood or other suitable material, are so disposed as to lie ush or even with the container chime. Such a construction, by way of example, is presented in Fig. 9 wherein the shell is produced exactly as hereinbefore describedwith a staple connection 21 between its overlapped side edges. This shell is likewise fitted with circumferential bands B applied and secured byvstaples Il and I9, the same as before explained. In the construction of this shell, however, the outer band edges lie fnsh, or substantially so, with the container chime requiring that the head H Venter Within the shell there to be secured as by nails 30 driven through the band and shell Walls, as indicated. For such a construction plywood or other suitable material may answer as satisfactorily as metal for the bands.

A further modified constructionns illustrated in Fig. wherein the side edges I0 of the panel are brought into butt relation when formed into a cylindrical shell. I'he connection between these edges may then include a strip 35 which laps the adjacent side edges, permitting the application of staples 36 which, through the medium of this connecting strip, serves to hold these .edges closely together. The ends of the strip may terminate adjacent the inside edges of the circumferential bands B at opposite ends of the shell, or it may overlap or underlap these ends, or either of them, to terminate adjacent the outer edges of the bands. If desired, a spot weld 31 may connect the butt joint strip at its ends with the circumferential bands, as shown in Fig. 10.

In the manufacture of containers, particularly those of larger size, special problems arise inconnection with storage and shipping, due to the large amount of space. required. It is accordingly desirable in many-cases, that the user of these containers set them up in his own plant to min-l imize the problems of storage and shipping. According to the method of construction herein disclosed, it is feasible to produce the panels with attached bands at the manufacturing point for shipment in flat condition to the user who will then, as occasion arises, `bend the panels with attached bands into shell form, secure each shell as by stapling and welding, apply and secure one head in place, fill each container with its intended contents, and, lastly, apply and secure the remaining head in place. 'I'he present container lends itself readily to such a sequence' of operations. It may, of course, be suppliedcomplete and erected by the manufacture, particular' ly in the smaller sizes, leaving tothe user only the task of filling and securing the second head' which is last to be applied. The exact procedure is one which may be determined according to circumstances.

I find it expeditious to produce a barrel according to the method herein explained. rPreattachment of the metallic bands which at a later stage become reinforcing hoops on the completed container, may be accomplished accurately and securely. Furthermore, upon completion of the cylindrical shell, annular seats are provided to receive the heads. The securement of these heads does not require any additional parts, unless some such construction is employed as is suggested in Fig. 8. It will be observed, therefore, that from start to finish the attachment of the bands to the panel, the securement of the panel edges and strip ends, and the locking in place of the heads may be performed entirely with the aid of machines which will operate rapidly and with a minimum of timeand expense. It has further been found in actualpractice that if the outer lap of theV bands are not secured in a manner such as herein described, so as to function as an integral unbroken ring, that a head, due to pressure from within the drum during handling will be pushed out at the lap, as the metal band gives easily at this point.

There is one further feature of importance to be noted, viz., the optional wetting of the panel face which becomes the exterior `surface of the completed shell. In the forming of smaller sized shells, say those with diameters o f five or six inches, the plywood is required to bend about a short radius. While so bending there is a tendency for the plywood panel to break or crack, thereby weakening the resulting shell. By moistening the outermost ply of the panel preliminary to the bending operation, I minimize this danger, due to softening of the wood bers which in this particular ply must stretch and yield the most. In thus applying moisture it is unnecessary that the remaining ply or plies, or adhesive material between them, be aiected in the least, and, in fact, it is probably desirab-le that they should not be subjected specially to the pressure of moisture in order that the cornu pleted shell may retain the maximum of strength and permanency.

I claim:
