JACKETED CAN.l

PECIFICATION forming part of Letters Patent No. 613,771, dated November 8, 1898.

Application filed March 10, 1898.

To @ZZ whom it may concern/.-

Be it known that I, JOSEPH B. LONG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Jaeketed Cans, of which the following is a specification.

The present invention relates to that class of cans, usually made of tin or other sheet metal, which are used for shipping purposes and which are provided with jackets for the purpose of protecting them.

The invention consists in the features of novelty that are hereinafter fully described with reference to the accompanying drawings, which are made a part of this specification, and in which- Figure l is a sectional elevation of a jacketed can embodying the invention, a part of the can and its jacket being shown in elevation, the remaining part of the jacket being shown in vertical section and the remaining part of the can being omitted and its position indicated by dotted lines. Fig. 2 is a horizontal section of a portion of the jacket on the line 2 2, Fig. l. Figs. 3 and 4 are vertical sections of fragments of thelower portions of jackets embodying some `features of the invention under two different modifications, a fragment of the lower portion of the can being shown in each gure. Fig. 5 is a section on the line 5 5, Fig. 4.

A represents the can, which preferably is provided with a bai-l B for convenience in handling it. The body of the can is preferably cylindrical and the top conical, and at the junction of the top and body the can is provided with a projecting flange ct, one object of which is to prevent water from entering the space between the can-bod y and its jacket.

C represents the jacket proper, and D the bottom thereof. The jacket is made of a single piece of sheet material of such dimensions that it may be bent to conform to and completely cover and inclose the sides of the canbody, preferably extending from the under side of the marginal flange et downward to a point somewhat below the bottom of the can. The material which I prefer to use for making this jacket is very thin wood having its iber disposed vertically, so as to facilitate Serial No. 673|352. (No model.)

the bending or rolling of the sheet to the desired shape; but, if desired, any other nonmetallic substance, such as paper or sheet material made from wood pulp or other ground vegetable ber, may be used. Thin wood is, however, preferable; In order to strengthen and protect the top and bottom edges of the jacket, they are bound, as shown at E and F, respectively. Each of these bindings consists of a strip of sheet metal, preferably tin, which is doubled longitudinally upon itself, and between the two folds thus produced the edge of the sheet of material of which the jacket is to be formed is placed. With the two strips of binding material in -place upon the two opposite edges of the sheet of which the jacket is to be made, the three parts are then passed between rolls, which press the twov laps of each of the bindings together and at the same time flute or corrugate the inner fold of each binding. The advantage of this is that it presses the flutes or corrugations into the surface of the material of which the jacket is made and causes the bindings to take hold thereof with sufficient rmness to prevent them from thereafter being displaced. Furthermore, the iuting or corrugating disposes of the fullness which naturally results from bending the bindings to the described circular shape, and it causes the jacket to retain the shape which is given it by the action of the rolls. As shown more clearly in Fig. 2, the ends of the bindings and the longitudinally-disposed edges of the sheet of which the jacket is made do not overlap, but the joint or space between them is`covered bya strip C', preferably of the cross-sectional shape shown in Fig. 2, the ends of which are soldered to the bindings. Afurther advantage of the iiuting or corru gating is that the indentations thus produced will provide spaces adjacent to the outer face of the canbody, so that a limited circulation of air may take place through these spaces. This is important,because frequently moisture gets into the space between the ljacket and the can, and unless it is disposed of it causes the can to rust; but however much this may be guarded against it cannot be altogether prevented and in course of time the can will leak. I therefore secure the jacket in place by means which will enable it to be readily and quickly IOG removed and again replaced without any appreciable cost. To this end I prefer to secure to the upper margin of the jacket one or more flexible tongues G, which are adapted to be bent inward over the top of the can or the iiange ay thereof for the purpose of holding the jacket in place. These tongues are preferably made of tin and are secured to the inner surface of the upper binding by means of solder. They are not required to be very strong, for the reason that the jacket usually iits the can with more or less snugness and would in many instances remain in place withoutV any means other than its frictional contact with the can for holding it. The tongues may be easily bent back when it is desired to remove the jacket and again bent inward when the jacket is replaced, and even if by repeated bending they should break o they can be replaced at a trilling cost by any tinker.

In its broadest aspect the invention is not limited to any particular means for securing in place the bottom of the jacket. In Fig. l I have shown the bottom as consisting of a thin disk D, preferably of wood, resting upon a hoop H, preferably of wood, which is placed within the lower part of the jacket and there secured by means of tacks, rivets, or other similar devices. In place of this, however, I may dispense with the hoop and use a thicker disk of wood, as shown at D in Fig. 3, the disk in this instance being secured in place by nails, as shown; or, again, I may use a thin disk with its margin bound with a strip of metal, as shown at d in Fig. 5. In this case in order to take up the fullness due to the bending of the metal and at the same time to make a more permanent connection between the disk and its binding the binding is fluted or corrugated, as shown, the iiutes being forced into the disk. Where a metalbound bottom is used, it is soldered to the lower binding F of the jacket.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. As a new article of manufacture, a cali having a jacket made of a sheet of wood or similar material bent to a cylindrical form, and sheet-metal bindings embracing the edges of the sheet, each ofsaid bindings consisting of a strip of sheet metal doubled upon itself to provide two folds, the folds being firmly pressed against the opposite faces of the sheet and the inner fold having flutes or corrugations extending into the surface of the sheet, substantially as set forth.

2. As a new article of manufacture, a can having a jacket made of a thin sheet of Wood or similar material bent to a cylindrical form and bound at its edges with sheet metal, each binding being made of a strip of sheet metal doubled upon itself to form two folds and curved transversely to conform to the curvature of the can, the inner fold having flutes or corrugations extending into the surface of the sheet, and a disk secured to and closing the bottom of the jacket, the flutes or corrugations leaving open spaces between the bind ing and disk, substantially as set forth.

3. As a new article of manufacture, a can having a jacket made of thin sheet-wood or similar material bent to cylindrical form and bound at its edges with sheet metal, each binding being made of a strip of sheet metal doubled upon itself longitudinally to form two folds and curved transversely to conform to the curvature of the can, the inner fold having flutes or corrugations extending into the surface of the sheet, and a disk having a marginal binding of sheet metal made of a strip doubled upon itself longitudinally to form two folds and curved to conform to the periphery of the disk, the folds having flutes or corrugations extending into the disk, the binding of the disk and the binding at the bottom of the jacket being secured together, substantially as set forth.
