' no mn'r r. e r-swear, or JAMESTOWN, NEW some SHEET-HETAL RECEPTACLE,

Specification of Letters Patent.

To all rwliom itmay concern .Be it known that 1, ROBERT P. SmnwAm, a .citizen of the United -States, res1d1ng at the ,cityof Jamestown, in the county of- Chautaii'qua and State of New York, have invented certain new and-useful Improve ments in Sheet-Metal Receptacles, of whichthe following, taken in connectlon wlththe accompanying drawings, is,a specification.-

-The invention relates to the construction of sheet metal receptacles, and the improve- 1: mentconsists in providing a return-bend in; wardly inclined chime and an inturnedan-r gular .flange onone end of the receptacle,

and .a cover having 'an outwardly flangededge which inclinesat the same angle as .the' chime so as.to .fit snugly .therewithin;

secondly, to provide a coping or bent over portion of -;the chime beneath which one edge of the flangcdedge o-f-the. covermay be inserted, after which the cover may' be s rungjnto a close fitting position within t e chime thereby holding it firmly in place; and, thirdly, to provide openings through the adjacent rim s;of the cover and chime;

whereby thetwo may be sealed with a wire seal or may be 'fastened' by other looking or attaching means; and. the invention consists in the construction and combination of the'parts as shown int-his'specification and the accompanying drawings and pointedout in the claims.

In the drawing,

view of the receptacle. Fig. 3 is a Sectional view of the upper part of the rece tacle at line W W in Fig.4. Fig. 4 is a an view of the receptacle and cover with t e seal in place. Fig. 5 is a sectional view of the rim of the receptacle and cover at line X X in Fig. 4; and Fig. 6 is a sectional view of the rim of the receptacle and cover at line Y Y in Fig. 4; and Fig. 7 is a sectional view of of the receptacle whereby said rim is permitted to spread. slightly in order that, the cover may be sprung into place therewithin. Fig. 9 is a sectional view at line W W in Fig. 4 of the lower end of the receptacle showing the inwardly extending chime for Figurel is a perspective view. of the cover; and g. 2 is a simllar i hold for the. protection of said-lower end and for convenience in handling the same.

. Like numeralsof reference refer to coritself in a return bend for a short distance and is then turned inward at an angle from tlie'sheet metal side in a flange 12, which flange preferably bends upward slightly at the inner portion. The return bend'top por-v tion forms the chime 13 of the receptacle which is inclined inward slightly to hold the fcover 16 and for convenience in handling. {lhe lap seam 11 extends up to the chime 13 of the receptacle and in the chime is formed .with an .open seam, the end 14 extending within the return bend 15 of the edge 13 when the two oppositely lapped edges of the seam 11 are brought together. This permits the inwardly inclihed upper edge or chime 13 to expand slightly under. pressure from within. 'The cover 16 is formed from a sheet of metal with an outwardly turned flange 17 around the edge which is inclined inward at the same angle as the chime 13, so that said flange 17 fits closely within the chime, 13 when it is sprunginto place there-,

in the. open upper end of the seam 11 per l'nitting the cover 16 to be sprung into place, yet holding firmly against, the same when once it is inserted. The chime 13 on the opposite side from the upper end of the seam 11 is bent inward, as'shown at 18, so. thatit holds firmly over the upper edge of the flange rim 17 of the cover 16. The in bent portion 18 also forms a strong handlifting heavy barrels or 'receptacles.

It is apparent that the cover 16 can be inserted. beneath. the bent over portion 18 and .then sprung into place on flange 12 within thechime 13. The slightly upward bend of the flange 12, as shown in cross section, forms a dead air space 19 between the cover 16 and the flan 'e 12 and chime or rim 13 which aids in sealmg the contents within the receptacle. This space 19 may be filled With solder to permanently close the joint. The two rims 13 and 17 standing adjacent to one another may also be rovided with one or more holes 20. and 21 t rough which a wire seal 22 may be inserted thereby seal- Patented Aug. 4, 1914..

ing the contents of the receptacle. The holes 21 within the flange 17 of the cover 16 provide openings intowhich a tool may be in- I sorted to pry over the rim 13 to remove the cover. It is usually preferred, however, to extend.- the. flange 17 in alug 23 having a hole therein-which permits the insertion of a tool-into said hole to ry across th'ejto'p of the chime 13 and there y easily start the ,25- with the bottom 26, as shown in Fig. 9,-

andsaid chime is preferably bent inward 80 in a coping projection 24, which isprecisely similar-to that shown at 18 in Fi s. 2, 3, 4

-"andfiand' in direct line with. the

,part 18. so that grappling irons can be inserted-beneath the two with absolute surety I5 oft-heir not slipping from the chimes 13 and 25, thebent over portion increasin the holding stren h of the chimes at t ose points. 'Said' nt'over ortions 18 and 24 s also form convenienthan -holds in handling in barfiels,'as do also'the chimes 13 and 15.

It is apparent that the return bend portion 13 and flange 17 ly' flatly adjacent to one-another and exte iiiing beyond. the

cover 16 permit ef'the use of: a. spot or continuous weld around the same, as does also the returnb'endchimes 25 and bottom 26,

thereby absolutely sealing the contents of ;tlie= receptacle for .ioreign shipment and similar ueeawhich place extra strain upon nt over I arcane;

all such. constructions. The rece tacle, how- 40 ever, is intended as'a removab e cover re-. ceptacle which canbe reused as desired, but the construction permits of the permanent fastening of the parts if so desired. -I claim as new 1. In combination with a can cover'having an outwardly extending flange arranged at its acute angle to the cover, a can body hav-.

ing its upper end turned over u on itself Y and disposed inwardly at an incline to the planeof the-body to provide a contracted mouth for the bod the free end portion of said upper'end o the can body being inclined upwardl whereby when the cover is seated-on'said ange a dead air space is provided between the cover and body, said upper end of the can body having a portionthereof bent inwardly and downwardly to engage the upper free edge of the cover flange.

2. In comb ination with a can cover having an outwardly extending flange and a can bod having its upper end turned over u on itse and formed at its free end-wit a flange that supports the-cover, and a lug integral with the free edge'of the cover flange, said lug havin anapert ire therein to re-' 'ceive' a'tool w erebythe cover may be removed by engaging the'tool'with the. upper end vof the can body and depressing the outer end of the tool. r a In testimony whereof I have afiixed my "signature in the presence of two witnesses.
