To all whom' it may concern: I

- arches oi'me ial, and to give the cap such a form that said Be-it known that I, FRANCIS w. n. CLAY, a citizen of the United States, residing at Pittsburg, in the State of Pennsylvania, have invented certain new and useful Improvementsin Bottle-Closures, of which the following is a specification.

My invention relates to closing devices for bottles,

jars, and the like, and particularly to metallic bottle caps.

The primary objects of the invention are, to provide for maintaining the pressure necessary to effect a seal by means of the i esiliency in the metal of the cap and to provide for a more secure holding of the cap and to render the putting on and removal of the same easy.

More specifically, oneobject of the invention is toprovide acap engaging the bottle head by the edges of arches of metal may be used as levers to induce-a pressure by clianging the angularity or convexity of the arch, and/to maintain resilient pressure bymea ns-oi such arclf tending to return to normal position under the stresses.

Another object is to design the cap in such form that the internal pressure on it will tightenits'grip upon th-e'bbttle head. 7

These objects, and other advantages which will hereinafter appear, are attained by means of the construction which is illustrated in the accompanying draw-- ings. 1

Figure 1 is a side elevation-oi a bottle cap, and Fig. i

2 a convenient form of bottle head for use with the same. Fig. 3 is a top plan view of the cap in normal shape.

; Flg.=4 shows a section of the cap placed on the bottle ready for operation of the tool, and Fig. 5 a section of the cap as fixed in place, both sections being on-line (6) of Fig. 3. Fig. 6 is a side elevation of the cap closed in place on the bottle head. Fig. 7 is an under-side perspective' view' of the bottle cap, and an outline of the placing tool shown therewith, illustrating the action in changing the bends of the arches of metal. Figs. 8 and 9 are respectively a top plan and a side elevation of a modified form convenient for use on fruit jars and to be operated by hand. Figs. 10 and 11 are central cross sections, respectively on the lines (12) and (13) of Fig. 8, showing the holding ring and cover in place on a jar. 'Fig. 12 is a fragmentary diagram of the hold- Ying arch, illustrating the effect on the arch of internal pressure in the jar or bottle. I

From'the drawings it will be-seen that, in the form of the invention shown the bottle cap 15 comprises a cover which has'an attached skirt or flange which flange consists of a series of upward and outward bent arches 16, integral with the cover, and'alternating therewith the downward and inward bent gripping arches 17, separated by slits 18 from the cover and adapted to engage under the rim or ledge 19 of the bottle head.

From Figs. 4, 5, and-6 it will be seen that in normal position the cap isplaced on the bottle head provided inside with a packing disk 20and' the bead 15 of the cap fits snugly over the top rim of the bottle; in this condition the upper arches 16 stand out at a rather wide angle and are well rounded, and the downward arches 17 snap under the ledge 19 of'tlie bottle. The cap is then pushed down to settle it neatly in place on the packing 20 and at the same time or just afterward the arches 16 are depressed, which will shove the gripping arches 17 under the ledge; the upward arches 16 may be then squeezed or'contracted into a smaller bend, (b

as shown in Fig. 6). The tool for accomplishing this may be of any suitable form desired. 7

Referring to Fig. 7 it will be seen that changing the inclination of the apex of the arch 16 by means of any convenient tool such as indicated at 21, in dotted lines will press the gripping arches 17 inward so that they take hold by their edges upon the ledge 19 of the bottle.

Thereupon the outward arches 16, being further engaged by the slots 27 of the tool as shown in dotted lines,

will gradually pinch up the arches into sharper bends b as illustrated in dotted lines. The effect of this is to give an additional inward thrust to the gripping arches 17, and when the tool is removed the natural tendency of the resilient metal to open the bends b again has the effect of still further thrusting downward and inward the gripping arches 17. The arches 17, having been flattened by pressure on the bottle,-now tend to close again and thus tighten their grip. While the tendency of both arches is to return to the original shape, they operate to off-set each others movement to someextent, but both tend'to tighten the grip. The arch which is compressed should always have a smaller bend than the gripping arch.

It will be evident from this construction that the cover of the cap is positively drawn down with a strong resilient pressure upon the packing 20' by means of the lever action of the arches,17 ,lancl that the natural resiliency of the metal will not only maintain this pressure but constantly tend to increase it as the gripping arches 17 press inward and upward. The internal pressure on the cap taking effect through rigid anclies 16 tending to lift them, will act on the outer sides oi arches '17 and tend to revolve them inwardly, thereby tightening the hold on the bottle and rendering it impossible to slip or give way without rupture of the metal. On the other hand by engaging any tool, such as a knife, or key, or screwdriver, under the outwardly flared skirt of the arches 17, the cap may be easily loosened and removed. Where there is not great internal pres- 'tiQ lfm use on fruit and pickle jars, to be opera'fi' by hand. An open rihg 28, made resilient against buc- 1 ing; consists of a holding portion 29 to engage the glass of a fruit jar 31, and outside this is.a skirt consisting of upward .bent integral arches 32 and down-- ward bent severed arches 33, which latter are pushed lnward to make the distance between them smaller.

than the diameter of the ledge 34 of the jar. As shown by dotted lines in Figs; 10 and 11 the ring is pushed down over the sloping ledge 34 and the conical ring is thus opened or spread so as to snap the arches 33 under the lid. The tendency of the metal ring'to regain its normal. position, as indicated by the dotted lines below, will cause the gripping arches 33 to push upward on the ledge and draw down the cover 30 by means of the rim' 29. I

In Fig. 12 I have illustrated the action of the upward pressure on the cover, showing how it tends to cause the gripping arch 33 to turn inwardly at f by reason of the action of forces f f f caused by the upward pull on the rigid arch 32. Thus while thering may be easily put on by hand it produces its own constantly exerted and resilient pressure upon the mouth of the jar and this pressure is augmented by the aetionof' the internal pressure lifting on the rim. i g In many forms of the device, for convenience a skilled mechanic can make provisions for taking up the surplus metal on the outward bent portion 16, butusually the pressure of any circuinferentii il tool will effect a pinching up of the arch'btas shown in Fig. (i, and the metal is'thus takenup, lWhen tle arch b is pinched by-a slotted tool, the effect is mucl betterand the upward bend being thus small and forming a stiff ridge in the flange, the cap is more securely held in its proper condition after putting it on the bottle. It will be understood that the forms of the invention shown are merely for illustration and the skilled me chanic will readily develop other forms and uses of it.

What I claim as new and desire to secure by Letters Pa txzzt, is the following: I Y

1'. The combination with bottle having an external ledge on the head, of a closing cap provided with downwardly inclined arches or bends adapted to engage said ledge by their edges, and also means'on the cap for thrusting downwardly and inwardly said engaging arches.

2. The combinationwith a bottle head, of; a closing cap comprising a cover, a series of inclined arches integral therewith and a series of intervening inclined archesse'i; cred therefrom, said arches being depressed and engaging the bottle head, substantially as set forth.

fh'lhe combination with a bottle head having .an e.\

ternal annular ledge, of a stopper cap comprising a cover 5 and an inclined skirt or flange, parts ofwhich flange are severed from the cover and depressed into locking engage: ment with said shoulder. I

4. The combination with a bottle head, of a closing cap comprising a COVGI' portion having attached thereto downwardly and inwardly bent arches of metal and intervening upwardly and outwardly bent arches, the downward bend engag'ing'the bottle head by the edge of the metal and both arches standing at an, acute angle with the plane of the cap.

A bottle closing cap llraving a flange with severed portions bent'int'o downward arches gripping the bottle by their edges, said arches sthnding at an acuteang-le with the vertical when in place n the bottle. i k

6.. A bottle closing cap comprising a cover having a radially Iluted flange, the downward bends of said flange being severed from the cover and standing at an acute angle with the cover, and the upward bends-being compressed to hold inward the downward arches to engage the bottle head on the edge of the metal, substantially as described.

7. In a bottle closing device, the combination with the .h ottle head, of a metallic cap having a continuous rim .with portions severed and depressed into position to engage the bottle head by the edges of the metal of such depressed portions, the rim being inclined to the vertical.

In testimony whereof-I have hereunto signed my name' in presence of two witnesses. v
