SHEET-METAL CAP-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 714,303, dated November 25, 1902.

Application filed July 31, 190i). Serial No. 25,371. (No model.)

To all whom it may concern.-

Be it known that LEDMUND HOFFMAN, a citizen of the United States of America, residing in Bridgeton, in the county of Cumber- 5 land, in the State of New Jersey, have invented certain new and useful Improvements in Sheet-Metal Cap-Olosures,of which the follow ing is a true and exact description, reference 7 being had to the accompanying drawings,

to which form a part thereof.

My invention relates to the construction of sheet-metal cap-closures, and has for its object to provide a closure of this kind the walls of which will be of great strength and I5 rigidity and which is adapted for use on bottles or similar receptacles having outwardlyprojecting locking-lugs; and my invention, broadly speaking, consists in form'ing'a sheetmetal cap-closure with outwardly-pressed channels extending upward from or near the edge of the closure and with laterally-extending outwardly-pressed channels communicating-with the upwardly-extending channels, both channels being adapted to give passage to and engage with locking-lugs on a bottleneck. By preference I form the bottom edge of the closure with an outwardly-pressed beading, connecting the outwardly-pressed and upwardly-extending channels, such a beading materially increasing the stifiness of the cap.

Reference being now had to the drawings which illustrate my invention, Figure 1 is a side elevation of a cap embodying. my new construction. Fig. 2 is a sectional elevation taken as on the line 2 2 of Fig. 3. Fig. 3 is a cross-sectional plan view taken on the line -3 3 of Fig. 1. Fig. 4 is a sectional elevation taken on the line 4 4 of Fig. 1. Fig. 5 is a side elevation of a modified cap embodying myinvention, Fig. 6 being a cross-sectional elevation on the line 6 6 of Fig. 5. Figs. 7 to 14, inclusive, are side elevations of other modified forms of caps, all embodying my invention. Fig. 15 is a side elevation of a bottleneck such as my caps are adapted to be used with, and Fig. 16 is a plan View of the bottle-neck.

A, Figs. 1 to 4, inclusive, indicates one form of my cap, A, Figs. 5 and 6, a modification, and A A A A A, A A and A the other modifications already mentioned.

B indicates a circumferential beading at the top of the cap in the modificationsindicated at A, A, A A and A, 1), Figs. 2, 4, and 6, indieating a layer of cork which is in this style of cap-closure secured in the upper part of the cap, similar layers being in the other modifications secured in cases A and A in the spaces indicated at B, in modification indicated at A in the spaces indicated at B immediately above the corrugation B and in the modificatio n indicated at A in the space indicated at B C, in modifications A, A, A A, A A and A", indicates a plane circumferential band, in which the outwardly-pressed channels are formed. In the modification indicated at A the portion of this band situated below the horizontally-extending channel is corrugated, as indicated at G, and in the modifications illustrated at A and A the corresponding portion of the cap is shown as vertically corrugated or crimped.

D is a circumferential outwardly-extending 7 5 beading formed at the bottom of the capclosure, being in all cases where it is shown, except the modification A, flush with the outwardly-pressed channel E.

E is the upwardly-extending channel leading from the bottom of the cap or from the beading D and communicating with a laterally-extending outwardly-pressed channel E, the lower shoulder E of which is engaged by the locking-lugs on the bottle. By preference, though not necessarily, the substantially horizontal ledge E is connected with the upwardly-extending channel E by an inclined shoulder E though without departure from my invention theentirelowershoul- 9o -der of the channel E may be inclined, as

shown at F. in Fig. 11, or all incline may be omitted, as indicated at E in Fig. 12. In

forming the lower shoulders E or E E it is sometimes preferable to slit them, as indi- 5 cated at E in Figs. 5 and 6. In the modification A Fig. 7, I have shown a plane band F l net-joint with the lugs of the bottle-neck by as interposed between the corrugated portion 0 and the beading D, and in the modification A Fig. 13, I have shown circumferential strengthening-beads G G as extending out from the plane portion 0. The modification A, Fig. 14, does not differ from the modification A except in being adapted for use with three locking-lugs instead of two.

Referring to Figs. 15 and 16, H indicates the neck of the bottle formed, as shown, with a plane lip portion H, from which extend locking-lugs H H indicating a heading below the plane portion.

It will readily be seen that any of the caps shown are adapted for use with the bottle H, and it will also be seen that my closure is one adapted for use with a simple and easilymade bottle and one which, by reason of the distribution of metal in compressing the channels E and E, or said channels, together with the heading D, forms an exceedingly stiff and strong cap and one of sightly appearance.

Having now described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A sheet-metal cap-closure adapted to fit closely overa substan tially cylindrical bottleneck having short outwardly-exten ding locking-lugs formed upon it, said closure-having its walls braced and adapted to form a bayooutwardly-pressed upwardly-extending channels E of a breadth slightly greater than the length of the locking-lugs on the bottle, and circumferentially-extending segmental channels E communicating with the tops of the channels E and also outwardly pressed, said channels E and E being adapted to give passage to and to engage the lugs on the bottleneck.

2. A'sheet-metal cap-closure adapted to fit closely over a substantially cylindrical bottleneck having short outwardly-extending locking-lugs formed upon it, said closure having its walls braced and adapted to form a bayonet-joint with the lugs of the bottle-neck by outwardly-pressed upwardly-extendingchannels E of a breadth slightly greater than the length of the locking-lugs on the bottle, and circumferentially-extending segmental channels E communicating with the tops of the channels E and also outwardly pressed, said channels E and E being adapted to give passage to and to engage the lugs on the bottleneck, said channels E being connected with and merging into a circumferential heading D at the bottom of the cap.
