CAN-BOTTOM.

To all whom it may concern:

Be it known that I, EDWARD G BARNETT, e citizen of the United States, residing at Concordvillc, in the; county of Delaware and State 'of Pennsylvanimj-lmw invented certain new, and useful Improvements in Can- Bottoms, of which the following is; especifieation. v

This invention tellic containers or remcptaclee and hes parcap bottoms.

Accordingly,'to this-end the invention has in view a. simple and substantial construction whereby the can bottom may be rigidly and 'firmlyunited to the body of the can to form ajoint which may not only be made watertight,-but whichwill also'morereadily withstand the shocks and jars incident to handling vessels 0i thischa-mcter.

- ticular reference to a. 'ncvel. improvement in weight of the contents of the can upon the bottom may be moreeft'jectualiy distributed. \Vitlrthe above and other objects in view which will more readily appear me the nature of the invention is better understood, the same. co isists iii the novel c'cnstructitm. combination and arrangement parts iieroinuftcr mercifully described, illustrated and claimed.

A. preferred and practical embodiment of the'inventirm is illustrated in the a0c0mpunying drawings, in whicl1- Figure 1 is an elevation of a can embodyinp; the present improvcment.-

Fig. 2 is an enlarged detail vertical sectirmul view showing more clearly the construction of the bottom portion of the can emlu'xlying the improvements vution in- Fig. 1

Similar references. designate correspond in parts thruugl'mut the several figures of the drawings.

In carrying the accent invention into effect, any rrlmmctcrmf. type of can body B army he used. That is to say,'tl1e present in Speeificdiilniof lietters Patent. Patented A Ap mamnmea .fnly 26,1918. serm1-uo. 111,5i9.

strong-end practical construction of the bottom portionF-of the can; v

Accordin i as will be observed fromthe drawings, the can body B is-forined at a point adjacent its lower edge with en in:

Wardly'prpjeeting annular bead 1, which providesan interior rib; one side of-w'hich' constltutes a bottom section abutment. The.

skirt or apron portion 2 of the body B 'e'xtendmg beyond the bciu'l or rib 1 ,is iormed at its end with :1 rolled hollow supporting, flange 3, wlu :b is of continuous; for'mution,' and. constltutes a remi'orcexrientfor the lower edge of the can body.

Fne bottom section-450i the can preferably includes the bowl portion and the oil'set continuous side wall 6, theifrce end-Tofwhich may be spun, ro1l.cd, cr' otherwise formed, into the same configuration us the hollow supporting flange 2 of the antibody;

whereby the said portion may constitute a hanger flange for embracing the continuous supporting flange 3 to hold the bottom sec tree 4: to the can body. WVhen the bottom section 'is telescopecl within 'the 'epron or portion 6-snugly [LbliiSflgfllllSfi shoulder presented by the interiorly p'ro ecting bead skirt portion 2 of the can bodygthe-shoulder Q I c1 rib 1, and the flange Tcu ages the hinges 3 whereby the edge of the ormer contacts; with the outer face vof 'the'skirt 2 forming ders-und an :u'mular groove to receiv'tl e sol thereby make a. Water-tight oint.-

Tbe fitting of thebottom. section 2: to the lower end of thc body, B in' "this Ira-zine: produces e tight 'tlmmglmutlhe lengtir of the conta-ctix g of the can body, und presents an annular groove orcuvity 9 btlzw'c'err the shou1dor'8 of the can bottom'uud the rib 1, which may receive a suitable quantity of solder 10 to firmly unite the bottom and belly ofthe .10 nt' which extends Parts of'tlic cull ,bottmfi w Portion-i1"- can at the under side of the l eud. The

provislioirot Solder at tl' ispnii t not only "insures u. perfectly water-tight joint),- but ulso covers or fills the space which would otherwise exist between the rib kind the con bottom and which could not be readily cleansed after the can -\\IIH used for shipping food, liquids and the= like. Thus, the row strurtion not only is of lllllml'ltlttt't' from a practical standpoint. but involves sanitai'y features as well.

To further increase the union between the body and the can, there-is preferably in-- sorted in the-cunbottom 4, inside the wall 6, a relatively- Stout compression ring 11 which may he riveted thereto as', shown at R, and the rirets-swetted witzlrsolder. 'lhis eompresfaionring serves the dual purpose (if-forcing the wall 6 f the rain bottom into firm engagement. with the shirt orapron portion 2 of the can body and'also eontitntes a bottom oft-base on whirh the entire canmay reSt. Thus, when the can is filled, the weight; of; the contents thereof resting upon the compression rin 11 'will have a tendency to always mnintam an effective joint: between .the bott0m section 4 and the bottom of the can body.

From the foregoing it will be'apparent that a nm el and distinctive feature of the present im'ention IS the, ]'Jl'()\lSlfJn of a can hav ng an internal head or rib which con stilntes an abutmentfor a flanged bottom set-lion. haying :1 rolled hanger flange '1' for engngingwi'lh asimilar anpporting flange fornnal at the lowrr; extreinityof the can body, in such a vay that theweight of the of the supporting llange of the ram lm y externalinthrreof. 'l'lie ring 11; while eonstit'uling'a haselor the entire ran. only sup ports the weight of' the eontenta of the vmel when the same is resting-upon the lluor'or groiind, but when the vessel is earried or tra'nsportml by th handle or bail shuwmlhe entire weight of the ronlrnt-s is illh'll'ilmtml over the portion fl iltlt' alt) the engagement of the members (i and '2. caused by the riU-ting of the eoni] |'i I 'lun ring it, and the inlerloeliiug-ofthe liiniger flange i' with the supporting i llange t IT- theran.
