Description

J. G. HDDGSON.
CAN BODY.
APPLICATION FILED JUNE 12. I915.
Patented Sept. 16, 1919.
UNITED STATES PATENT OFFICE.
JOHN G. HODGSON, 0F MAYWOOD, ILLINOIS, ASSIGNOR TO AMERICAN CAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
CAN-BODY.
Specification of Letters Patent. Patented Sept. 16, 1919.
Application filed June 12, 1915. Serial No. 33,644.
To all whom it may concern:
Be it known that I, J OHN G. HODGSON, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Can-Bodies, of which the following is a specification.
This invention relates in general to can bodies and has more particular reference to can bodies of the sanitary type in which the end closures are secured in place without the use of solder and through the formation of an interlocked seam.
Prior to my invention such bodies have been provided with a seam overlapping at its ends, the material of one of the edges near the flanges being cut back on an angle to within the flange and thence back on a greater angle to the can body edge. This construction has provided a small obliquely angled corner within the flange which has added materially to the thickness at that point and has rendered diflicult the forming of the flange and the interlocking of a can end thereon.
It is the object of this invention to eliminate this corner and to thereby provide a flange of more even thickness, a flange in e readily provided and a flange to which t e head of the can may be more easily seamed.
Other objects and advantages of the invention will be apparent as it is better understood from the following description when considered in connection with the accompanying drawin illustrating a preferred embodiment t ereof.
On the drawing, 4
Figure 1 is a side elevation of a can body embodying my invention;
Fig. 2 is a plan view of a blank for forming the same;
Figs. 3 and 4 are edge views of this blank; Fig. 3 showing it as cut and Fig. 4 as hooked and ready for forming into the can body;
Figs. 5 and 6 are enlarged sections taken respectively on the lines 5-5 and'6-6 of Fig. 1;
Fig. 7 is an enlarged partial top plan view of Fig. 1 and Fig. 8 IS an enlarged partial internal elevation of a seam end.
For the purpose of illustrating my invention I have shown on the drawing a can body formed with the lock and lap seam side connection. This can may be formed from a blank such as that shown in Fig. 2. From this view it will be seen that one edge 10 is notched at 11 to provide an extension 12 adapted to be formed into a hook 13 set inwardly from the ends it at this edge of the blank. The other end is cut away to' provide a central tongue or extension 15 adapted to be formed into the hook 16 in length coextensive with that of the hook 13 in which it is adapted to be engaged for the locking operation of the side seam, as indicated in Fig. 6. It will be noted from Fig. 2 that to form the hook 16 the extension 15 is folded back on the dotted line 17 and the extension 12 back upon the dotted line 18 to form the hook 13. The hooks thus formed lie behind and in front of the body of the blank and the portions 14 at the end 10 overlie the material of the blank beyond the ends of the hook 15 as indicated in dotted lines in Figs. 1 and 8. In order that the angle points of the material formerly disposed in the flanges may not be there provided, the edges of the blank beyond the hook are cut away along receding lines 19 throughout the parts located in the flanges. These parts lie between the edges 20 of the blank and the dotted lines 21. In the present instance this is accomplished by arouately curving the ends of the edge of the blank located at the end provided with the hook 15, as shown in Fig. 2. The length and curvature of this are are such that it arrives at the edge at the point 22 at which is located the edge of the lap portions 14 at the end 10 of the blank when the seam is made. In practice the lap portions 14 are soldered in position and are preferably disposed within the can, the connection being somewhat as shown in Fig. 5. Comparison of this figure with Fig. 7 shows the arrangement of the overlapping parts in the flange, from which figures it will be noted that no point or corner of metal is provided in the flange to increase the flange thickness.
It will be manifestthat the foregoing construction enables the provision of a more perfect closure and reduces appreciably any extra thickness in the flange at this point.
It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
5 I claim:
1. A can body having overlapping side edges and a flanged end, one of said edges receding along a curved line in said flange.
2. A blank for a can body, the same being 10 cut at one end with notches 11, to form a Witnesses.
