METHOD OF FORMING CAN-BODY FLANGES.
Specification of Letters Patent.
Patented Aug. 18, 1908.
Application filed. Februaryfi, 1905. Serial No. 2%,423.
citizenof the United States, residing at St.
Andrews, Province of New Brunswick, Do-
minion of Canada, have invented a certain new and useful Improvement in Methods of Forming Can-Body Flanges, and declare the following to be a full, clear, and exact description of the same, such as 'will enable others skilled in the art to which it pertains to-make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention has for its object the produc-' tion of a method for forming on can bodies, a reinforced flange to which the top or end (depending on the style or shape of can) may be soldered.
v In the manufacture of what are known as roll top cans the body is provided with an outwardly extending flange, usually at right angles to the plane of the body, to which the top is soldered after the contents are placed in the can and from which the top is torn (usually by means of a key) when it is de-. sired to open the can. In practice it has been found desirable to make this body flange of additional thickness to enable it to resist thetenacity of the solder, and my present invention relates to the method of forming this flange. 1
In the drawings Figure 1 illustrates the blankbefore it has been operated upon. Fig. 2 is a plan view of the blank after the first operation. Fig. 3 is a section on the line 33 of Fig. 2. Fig. 4 is a vertical section of the can body immediately after it has been formed. Fig. 5 is a section after the outstanding flangehas been formed thereon.
In carrying out the invention A represents to the proper size and shape. By any suitable machine or tool the edge a of the blank is bent or doubled upon itself as in Figs. 2 and.
3 to provide the thickened edge a. The
blank is then put into any of the well known forms of body machines and. formed into a body B, see Fig. 4. The style of body seam is immaterial.
of flanging machines and the flange 6 formed; Thus, I have produced a body B having the the blank, consisting of a sheet of metal cut' The body thus formed is then placed in any of the well known forms soldering flange 1), reinforced as desired, but
accurate in its dimensions, smooth on its surface, and forming a sharp angle With the body so that the top or end can be readily and effectually soldered thereto. It is obvious that many different machines and tools may be employed to turn and fold the edge of the blank; to form the body; and to flange the latter, and I do not limit myself to the use of any particular means for accomplishing these steps, the invention residing in the method of manipulating the blank to produce the desired flange on the body.
' What I claim is:
The method of forming a can body which consists in doubling the metal of the blank back upon itself at the edge which is to form the top of the can, forming a tube from the blank, and finallv bending the doubled portion of the bodylaterally at an angle. to the body proper to form a thickened. flange.
In testimony whereof, I sign this specification in the presence of two witnesses.
FRANCIS P. MoGOLL.
