Improvements in Sheet-Metal Containers,"
4of-whiclrthe following is aspecification.
This -.invention `relates to sheet-metal' conretainers,x with-'more particular referenceto dis ensingtanks yof comparatively large size, sue 4ras-:are used-to' contain carbonated water and? other liquids and. gases vwhich. exert fa high internal pressure, vfor which purposev 1.3 obviously, such-axcontainer-fmust be-ofgreat strength. I also-have in mind the' large'.- cans-1in--whichl-milkgis usually shipped to ma1'liet,:and thelar 'si-zesrof oil cans, both of which.4 when in :fserv-ice :are :subjected to 2-3 hard-usage and "which,{-. tl 1erefore, must be of exceedingly strong anderigid construction.
It willfbe apparent .that-'the vjoint between 'i is undoubtedlythe Apart-+5'-considering both .usagefin handling'andffinternal pressure, most -likelyklte'be affected' byT the various' strains,.and=therefore, this joint is, the part likely: -to first'vyield to such strains and ren'- 'der the` containers. unfit for use. y The present; invention' `Contemplates -means .for
' strengthening and protecting this joint and,
in fact,. theentire container, and thiswithout appreciably-ifY at allincreasing the cost-of-materials'and manufacture. n
I am aware thatthere are many ways in.'
which'the bottom'part of the container has been formed or :ons'tructed 'with the above ideas in mind, but'it has-been my experience that efforts to strengthen and 'improvegipon walls of the container 'ad- `jacent:theretohave generally been madeat the -eXpense-offdue economyv 1n the manufacunder thewell-known laws of the resistance ture of such containers. Thereis, of course,-
' v45 facturer cannot profitably'go, and the object of this invention is to provide a strong, durable and'tig'ht joint between the bottom and the body portions. of4 containers o f this class', and otherwise strengthen the entire' A structure, in the simplest possible manner,
" requiring the fewest4 possible operations inmanufacture, and without employing a heavier gage of sheet-metal throughout the whole container,l than would naturally be required to gi've the requisite strength to Y sped-freetime: -Lettrsratenm Arlilaon filed-Hamme, 190s: seria1N0 .41a,-1513.
this joint. l My invention will be more readily understood by reference to. the accompanying drawings, formingv a part of thisspecifioation, in whiohe- Figure 1 is a central sectional elevation of a sheet-metal container 'embodying my invention; F ig. 2 is'a central section of the bottoml of the container; Fig. 3 is a cent-ral sectionl through the lower portion 'of a container illustrating a slight modification of -the preferredform as shown'in Fig. 1; Fig. t illustrates, the successive steps of the stamping,- operations? byA which 'the bottom of the container shown in Fig. l1 is formed, and Fig.A 5 illustrates .the steps ofthe stamping pjarts thereofother.: than those comprising tainer.A illustrated in Fig. 3 is formed.
Referring now-to the drawings in detail, numeral v11 refers tothe body portion of 'a common form of cylindrical sheet-metal container of the character to which I have-referred. lThe lbottom 12 thereof is formed from a-single aid separate sheet-metal blank of-circular form, whioh is first by a suitable pending double or U-shaped flange 13 (referring now to Fig. 4). The bottom, thus' flanged, is'now placed between suitable dies and by another operation that portion of the bottom boundedby the top edge of the inner vmemberof the liange' is forced downwardly in such manner that the rounded corner 14.- (Fig. 4) is depressed and theinner member 15 of the fiange curled or curved into the forced intoyielding contact with='the outer 'member 13- of the flange. I have now provided said bottom, at its outer edge, with a which isof sufficiently small diameter that of materials the strength of the outer edge of said bottomis materially augmented. It willbe noted that-in forming this annular cylindrical edge, or` hollow rim,the outer member 13- of. the flange remains in its originalvertical position, and the interior -diameter `of the short cylinder formed by said flange is substantially equal to the exterior diameter of the cylindrical body 11 of the container. The lower end of this body portion 11 is now inserted within the flange of the bottom 12, and forced between operations-ahy which-the bottom of the-constamping. operation provided with the deconfiguration shown, the bend 14 being depending substantially cylindrical rim 16,
the yieldingly contacting bend 14 and iiange 13 of said bottom and firmly seated, as shown in Fig. 1. Solder is now applied, preferably to both the outsideY and inside of the container, the iange 13 being thus rigidly secured to the sides at the end of said body portion, and a ring of solder 17 formed within 'the container to seal the opening between the bend -14 of the bottom 12 and the inserted end of the body of the can. This ring of solder not only seals the opening but obviously augments the strength of the joint.
It will be noted that the bottom 12 is formed by but two comparatively simple operations. Thus formed, this bottom is now applied to the can body and the soldering operations complete the container.
It will be apparent not only that I have provided a container having a bottom joint which will successfully resist ordinary internal pressure to which it may be subjected but one which is also capable of Withstanding the exceedingly rough usage to which such containers are frequently subjected. It is well known that thesetanks, :for whatever purpose they may be employed, particularly when of large size and capacity, are, in handling usually rolled along the bottom edge, and not infrequently dropped by carriers in such-position that vthis edge' receives the full y'force of the impact. It will therefore be understood why it is necessary that this part of the container-that is,
the lower edge thereof-be made of comparatively great Strength. The cylindrical configuration of the metal at this edge, in a structure embodying my invention, as will be apparent, forms a cushion which receives and to a certain extent distributes the strains, and even should suoli strains be sufficient to permanently distort or indent the metal,
vsuch strains will become distributed as to be practically harmless when transmitted through the metal to the vital parts of the joint. In 'forming this cylindrical edge, as is well known, I have, through the sharp curvature, vastly increased the resiliency of such metal as that of which these containers are usually constructed whereby distortions due to any ordinary strains of impact will be but temporary, the original configuration of the metal being restored through its own resiliency.
For some purposes it may be desired to add an additional strengthening element to this edge and joint, and, while such addition obviouslyadds somewhat tothe cost of manufacture, such cost may be compensated for through the increased strength of the retainer at this joint. For instance, as illustrated in Figs. 3 and 5, an annular wire ring 18 may, after the rst flanging operation, be seated inr the bottom of the groove provided by the U-shaped flange. When said'bottom is then subjected to the second forming operation, hereinafter briefly de-l scribed, the portion 15 of the double flange will, as the bend 14 is forced downwardly and outwardly, curl around thev ring 18 which thus forms a core for the cylindrical rim 16.
The extent to which body portion 11 of the container is forced downwardly in the cylindrical /rim 13 is obviously immaterial so far as my invention is concerned. I prefer that the lower edge of said body portion fall just below the bend 14 either where no core is employed, as clearly shown in Fig. 1, or where the ring 18 is used, as illustrated in Fig. 3. The soldering operations will now complete the container, so far as this joint is concerned.
I claim as new and desire to secure' by Letters-Patent 1. A sheet-metal container comprising a bottom and a -body portion, said bottom portion being formed to provide an upwardlydirected cylindrical flange within which the end of said body portion is inserted and to which it is secured, and said bottom portion being further formed to provide a depending tubular ring intermediate the bottom proper and said flange, forming a supporting rim for said bottom and for said container and lying wholly below the plane of said bottom and within the plane of said flange.
2. A sheet-metal container comprising a bottom and a 'body portion, said bottom portion being formed to provide an upwardlydirected cylindrical fiange within which the end of said body portion is inserted and to which it is secured, and `said bottom portion being further formed to provide a depending tubular ring intermediate the bottom proper and said flange, forming a supporting rim for said bottom and for said container and lying wholly below the plane vof said bottom and within the plane of said flange, and a solid ring within 'said tubular ring.
