PROCESS OF MAKING JACKETED CANS.

lpecieatton of Letters Patent.

Patented July 16, 191.8.

T o all 'lc/wm t may concern.'

Be it` known that I. BEN K. Fono, a citizen of the United States, residing in- ()ak lai'k, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Piticcsses of Making Jacketed Cans. of which'thetollowing is a specification.

This invention relates to improvements in of making jacketed cans.

Objects of the invention are to )rovide a simplified process of making a jaclteted can having the main portion of the jacket formed by a tube composed of layers of paper; to prtividf` a process of making a jacketedifau in such a way that the can is provided with a jacket coveringsubstantially all walls thereof; and to provide a process wherein the manner of forming the joint be tween. the top and the body of the can in sures a strong.` rigid and uniform construction. 1

The invention furthermore consists in the improvements in the steps and novel combinations of the steps of the process as herein shown, described or claimed.

In the drawing forming a part of this specification I have illustrated various steps used in carrying out my improved process, and in said drawing Figure 1 is a vertical danietrical sectional view of the paper jacket.` the same being s own with an annular can-supporting strip secured to the bottom thereof and the dotted lines indicating the wooden disk bottom of the jacket. Fig. Q is a sectional view of the can body and top, the same being separated and showing in detailthe manner of formin the top before it is soldered to the can y proper. Fig. 3 is a sectional view of the can and jacket as the same are assembled and showing the can'top as already soldered to the can body, and Fig, 4 is a detail sectional broken view showing the finished article produced by my process. l

In carrying out my process, a cylindrical paper tube 10 is formed by winding several layers of paper on top of each other'by any well-known method, the tube being cut to proper length to fit the can and, as will be understood, this tube is made of such a size that it will slip over the can to be covered thereby. After the paper-tube l0 is formed, it has secured thereto an annular bindingl and supporting metal strip 11, the lower edge of which '1s curled outwardly and upwardly over the lower edge of the tube, the inner edge ot said annular strip forming a support or shelf 12 as shown. A bottom disk l-l of wood or other material is then laced within the tube on the supporting le(v ge 12 and thc jackgt is nou' read)l to receive the can.

As shown in Fig. 2. the can body 14 has secured thereto a bottom l5 by a double scam or in any other suitable manner. The can top is of peculiar construction and is provided with a countersuiil; portion lt surrounded by an upright annular wall 17 adapted to fit within the open top of the can body 14, said top being provided also with an outwardly extended peripheral flange 1B located in a plane intermediate the top and bottoni of the annular wall 17 for a purpose hereinafter specified. The can top formed in the manner above described, is laced within the can body and soldered t creto as indicated at 19 in Fig. 3. The can body and top in this condition are next pl within the jacket as shown in Fig. tigjafter which a top disk 2() of wood or other suitable material is placed in the countcrsunk portion of the can top. Following this, the peripheral flange 18 of the can top is curled downwardly over the upper edge of the paper tube jacket and the latter is pressed inwardly against the wall 0f the metal can as indicated it 21 in Fig. 4. The upper portion of the wall 17 of the can top which, as clearly shown. is of double thickness, is folded in'wardly and pressed down onto the top 2() to slecure the latter in place, as shown most clearly in Fig. 4.

From the preceding description it .will be seen that I have provided a simple and relatively inexpensive recess for manufacturing jacketed cans in which the jacket extends over all walls of the can and that the manner of securing the tube and top of the y can by means of the can top itself, insures a strong and rigid construction.

By the use of the term paper I wish it to be understood that I mean any fibrous material which can bejormed into a 'acket in the manner described and that Ialt ough I have herein described the process as applied to the manufacture of a cylindrical can and jacket, yet it will be understood that the process can be carried out with jacketed cans of different shape and construction. It will furthermore be understood that it is imma telial whether. the jacket is formqmbefore l .formed simultaneously before the two erts `exaggerated in order to more clearly i11usu trate t/he construction.

I do not claim herein the can or container, the seme being the subject of my pending plcation Serial No. 802,372, filed Nov. 22, isn. f i

I chum 1. A 4process of manufacturing jaoketed cans, which consists in firstseparately forning a com lebe oircumferentially continuous jacket b y, a complete can bodjf, and an incomplete flanged cover adapted to fit within the een body and having an edge adapted to extend be 'ond the edge of the can and jacket bo ies; and second, assembling t e same by inserting the can body longltu inally lwithin the jacket and the cover within the body; and, thirlL bending the. edge ol' the cover to clench the jacket and ran bodies to each other and to the cover.

The process of manufacturin 1 jacketod cans, which consists in first provi( ing independent jacket and can bodies, a closure having an outstanding flange and an opstanding flange located at its edge, and a jacket disk; and second, assembling said parts, the can body within the jacket body, the closure within the can body and the disk with the closure; and third, bending said flanges in opposite directions, the outstanding flange to clench the jacket und can bodies together and to the closure and the opstanding flange to incase the end jacket disk.

Signed this 18th day of November. 1913, in the presence of two witnesses.
