SHEET METAL .SHIPPING DRUM Fild Oct. 5. 1930 INVENTR Patentes Aug. 7, 1954- Wheeling Steel Corporation, W. Va., a corporation of Delaware Whecllng,

Application October 8, 1930, Serial No.-l86,080

'4 claim. (ci. 22o-s1) This invention relates broadly to sheet metal drums. and it has for its primary object to* provide a shipping drum which includes a readily removable and replaceable head and simple and L'. effective means for securing said head in place.

'Tis

In describing the invention in detail, reference is herein had to the accompanying drawing, in which- Figure l is a. head end elevation of a frag' mentary portion of a' drum embodying this invention; l

Figure 2 is a detail view in longitudinal section, showing the head end of the drum as it appears prior toclosing the end of Athe drum bod.v`into retainingrelatioii to the'removable head;

Figure 3 is a similarsection with the head secured in place; andl Figure 4 is asimilar section showing fiedform of head. i

Referring to `said drawing, 1 designates generally the body of a cylindrical sheet metal drum which has formed therein at a suitably spaced distance from the terminal edge of the head end thereof an inwardly directed, or internal, annular bead 2. The top surface of said bead constitutes a seating ledge 3` upon the inner edge portion of which may rest the under side of the outer edge portion of a circular wooden head 4. Said head` hasa diameter materially less than the internal diameter of the head end of the drum body, and-'suitably attached to the outer face of said head, as by means of short,

a modireadlly removablcbrads 5, is the inner edge portionof a resilient split ring 6, preferably made of steel. which normally, or in its fully expanded condition, has a peripheral diameter approxithe internal diameter of the head .end

o f the drum body.

Aierminal roll 7 is formed on said body by turning or rolling inwardly the Vmetal of the edge portion of the head end thereof subsequent to the mounting upon said seating ledge of the head 4 with the ring 6 occupying attached rei lation to thelatter. lSaid roll, which consti- 45 tutes a rimv for the end of the drum, occupies `said seat portion Vofthe body member, a`re- The ring 6, which may be formed of ilat material-that is, of even thickness through-- out-is perforated at suitable relatively spaced distances for the receptionv of the attaching brads 5. Each of the ends of said ring is pref- 60 erably beveled,- as shown at- 8, in'Fig. 1,'to facilitate movement of said ends relative to each other in expandingand contracting the ring. Holes 9 are preferably provided adjacent to each of said ends for'the reception of the point of a 65 hook or other instrument .by means of whichf contracting or drawing force may be applied for withdrawing the ring from4 its seated headretaining position.A

. As hereinbefor indicated. the ring is attached 'I0` to the head prior to introduction of the latter in its seated position within the endof vtime drum. Thus it is insured that the head shall be prop-- erly seated upon the ledge provided therefor land shall not become shifted from said position. 75 When the head is to be removed, the brads 5 may readily be pried up and withdrawn; whereupon said ring' may be contracted and withdrawn from beneath theroll 6, thus freeing the head for removal past said roll. -so

It is to be noted that the bead 2 necessarily possesses such relatively great depth that the ledge 3 formed thereby shall have materially greater width than the diameter of the subsequently formed roll 7.

In the modication shown in Fig'. 4,. a down- 'I wardly dished' sheet metal cover or head 4* is substituted forv the wooden head 4 described. Said head 4 has an annular seating flange 10 an interposed gasket 11.

What is claimed is:-

l'. A container comprising a container body member having an inward seat' portion spaced v from an extremity thereof, a closure member on 96 said seat portion o f the body member, and an inwardly retractible retaining member in retaining relationship to said closure member, the body member being deformed against the' :retaining member to hold the closure member 100 in place, the retaining member being substanwhich overlies the ledge 3 or which rests upon A9o -tially unobstructed inwardly thereof for `inwardly retractible movement, the closure member being removable from the deformed bodvmember upon inward retractionl of the retaining member. h1 015 2.5A container. comprising a container body member having an inward seat portion spaced from an extremity thereof, a closure'member on taining member in retaining relationship tosaid vui closure member, the body member being deformed against the retaining member to hold the closure member in place, and-means for 11xedly fastening together the closure member and retaining member.

3. A container comprising a container body member havingvan inward seat portion .spaced from an extremity thereof, a closure member on said seat portion of the body member, a retaining -member in retaining relationship to said closure member, the body member beingvdeformed against the retaining member to hold the closure member in' place, and means for xedly fastening together the closure member and retaining member, said means being accessible while said closure member and retaining member are in position with respect to said body member toA permit separation of the closure member and retaining member.

' closure member and retaining member are in position'with respect to said body member-to permit inwardly retractible movenent of the retaining member.
