Specification of Letters Patent.
' Patented Aug. 5,1913.
Application filed September 19, 1912. Saris-1N0. 721,327.
To all whom it may concern:
Be it that I, Anemia K. LovnLL, a citizen of "the United States of America, and resident of New Haven, in the "county of New Haven and State of Connecticut, have invented certain new and useful Improve'ments in Battle-Stoppers, of which the following is a specification.
My invention relates to a bottle stopper and has for its object to provide bottle closure mechanism which. shall within itself contain all the elements necessary to enable it to be applied to the'ordinary form of bottle or jar, without special construction of the bottle, 01: attachment to it of a art of the stopper mechanism separate om the remainder, but which may readily be a plied "or removed bodily without the aid of mechanical contrivances and positively held and secured by a resisting abutment comprising the ordinary flange, rim or bead commonly found on bottles and jars.
The specification and drawings comprise a substitute application in renewal of an application filed June 5, l911,'Serial Numher 633,338 and inadvertently abandoned A st 5, 1912.
he invention consists in the novel clo-' sure mechanism and arrangement, construction and combination of arts as more fully hereinafter described and claimed. I
In the accompanying drawings forming a part of this specification, Figure 1 is an elevation of a bottle fitted with my improved closure. Fig. 2 a central, vertical cross section through 1. Fig. 3 is a similar sectidn through if e external screw cap, but showing" the remaining parts in elevation. and art section, and with the mechanisms un stened, or in the operation of bemg applied to or removed from a bottle. Fig. '4 is an elevation similar to Fig. l of a modification of the device embodying the principle of'cams instead 'of a screw for ,forcmg the parts to place. Fig. 5 is a simila-r elevation with the parts in the position for bein applied to or removed from the bottle. ig. 6 is a central vertical, cross section of 5, and Fig. 7 is a horizontal cross section through 13g. 4 on the line 7, 7
Referring to the drawings, 1 denotes the neck of an ordinary bottle, formed the usual flange, rim or head, '2, around its mouth or opening, 3. Said rim or. bead usually comprises "an external enlargement of the neck, provided mainily to stren then and reinforce it for the'insertion of a cork, and it is generally found of varying thickness and depth in bottles of every size and description. It necessarily forms an annular shoulder .4 on'the neck, at its lower side, which shoulder has been employed as an abutment for various devices for securing the cork or closure of the bottle in place. lit performs this function in the application of my improved bottle stopper, which is described as follows: I
Upon the neck of the bottle is received a tubular ferrule5 having its upper part loosely fitting around the rim or bead 2 and formed with a screw thread 6. Below the thread the ferrule is of-expanding diameter,
or slightly conical increasing in size downdownward in anoutwa-rdly expanding collar 8, which is provided for, the purpose (if-gripping and'holding the ferrule, in the adjustment and fastening-of the closure in place 'on the neck of the bottle. The ferrule is formed with vertical slits 9 extending from its threaded portion to the bottom of the gripping collar, whereby such part is virtually divided into a series of sections or flaps 10 for the purpose of rendering it expansible and adapting the flange 7 to be slipped over the bead 2 and then sprung inwardly to engage it.
Fitted to screw upon the threaded part of the ferrule is a cylindrical screw threaded cap 11, provided with a disk 6 of cork or other suitable material at its upper end inside the shell thereof, which forms the bottle closure or stopper when the cap is screwed down upon the ferrule to engage the disk with the mouth of the bottle, as shown in Fig. 2. In the operation of ap lying the device to and sealing a bottle, t e ferrule is held in the proper position and from turnafter passing the threaded part of the ferrule will.eng'age-.the smooth conical part thereof below the thread, and by its camlift ill
l0 and engage the flange 'l with the shoulder ming action thereon will contract the flaps of the neclr of the bottle, whereby the action of the screw in forcing the dish down upon the mouth of the bottle, is counterbalanced by thev reactively upward strain and hold of the flange 'l upon the shoulder.
if the ferrule is of spring material and its normal shape is that in which the flange is engaged with the shoulder of the bottle, then the action of the screw cap will be confined to holding the ferrule in such engagement with the shoulder, and in the act of removin the ferrule the sections will yield and spring outwardly in passing over the shoulder. (in the other hand if the normal shape of the ferrule is its state of enpansion, then the cap will cam it to place on the neclr of the bottle as well as hold it in such position. if the ferrule he made of inelastic material, then in the act of oeing forced over the bead 2 the sections will be expanded, and the cap will subsequently cam them. into grappling engagement with the shoulder, and hold them there. All of these effects are contemplated in the use of the invention, dependent upon circumstances, but it is important that the screw threads of the ferrule should be wholly separated from the grappling sections, and that the inward cammingaction upon the sections, by the cap, or the function of hold-- ing them in the engaged position should be performed by a smooth annular part of the cap in engagement with smooth and unthreaded surfaces upon the sections instead of threadedsurfaces, for which purpose the non threaded part of the cap below the thread is provided.
in the constructive detail of the mechanism, it is preferable to make the ferrule as a split ring, or non continuous by cutting it longitudinally as indicated by the division 12 in Fig. 3. This enables the ferrule to be closed in and entered into the cap without being screwed therein, in connection with which result, if the lower ends or terminals of both the thread of the ferrule and that of the cap. be provided with stop shoulders respectively designated by the characters 13 and "i l, in Figs. 3 and i, such shoulders will actas stop mechanism for preventing the cap from being unscrewed from the ferrule beyond the limits of the threads and removed therefrom. By this arrangementthe cap and ferrule may be always kept together, and both wholly removed from or applied to the bottle atone operation. lhe a vantage of this, not only for the purpose of cleanin the parts, but for convenience in applying t e device to or removing itfrom the bottle, and also preventing mi'slaying or losing the part, or screwing them together'with the threads crossed and thereby injuring them, is of the utmost importance.
Though the ferrule cannot project more the mouth of the bottle, as the cap its dislr must be screwed down into contact with the neck, the znouth of the bottle may project above the ferrule, asshown inthe drawingahence a particular size of stopper is not confined to a particular height of the rim or beach-but may be used with various heights of the head, up to the point where the ferrule is flush with the 'mouth of the bottle. This provides for adjustment of the device to conform to various sizes of head in which the diameter remains unchanged.
Figs. 4- to 7 inclusive illustrate a modilication of the invention in which the cap 2i is formed with a pair of opposite cam slots 22, taking the place of the screw thread, and the ferrule 23 has a pair of external pins or projections Qtengaging the slots. With this construction the cap can be turned on the ferrule only about a half revolution, and the cam slots, to provide the'required range of movement of the cap are made of abrupt or steep pitch in their central parts, and of lesser pitch corresponding to that of the screw threads at the ends, where they engage the pins when the cap is screwed to place, as shown in Fig. ll, or in its extreme released position as indicated in Figs. 5 and 8. With the enoeption of the pins in place of screw threads the ferrule is of the sac construction as that shown in Figs. l, d and 3, the split ring construction enablingit to be placed within the cap by springing, and the pins thus engaged with the cam slots, and operating as stops to prevent the dis connection of the parts. it is evident that the slots could. be cut through to the lower edge of the cap as indicated by the dotted lines a" in Fig. l to permit the removal of the cap from the ferrule when the same comprises a solid ring instead of being made eapansible. The top edge of the cap should be provided with a milled band we to facilitats a hold upon it in removing it. i claim as my invention;
1. A bottle closure comprising in combi nation a ferrule for claspin the neclr of the bottle, provided with yiel g grappling sections for engaging the shoulder of the of the grappling sections from the flange and holding the parts together when removed from the bottle.
2. The combination of a. bottle closing cap, a ferrule fitted within the caphaving @lll Elli
litlh lltl its
expansible holding sections and abutments for grappling the flange of the bottle, means for drawing the cap axially on the ferrule to compress the expansible sections upon the flange by reaction of the cap against the mouth of the bottle, and stops for limiting the motion of the cap in the reverse direction after disengagement of the grappling sections to hold the parts together when removed from the bottle.
The combination of a ferrule for clasping the neck of a bottle, provided with yielding grappling sections for engaging the shoulder of the neck flange, a closure cap revolubly mounted thereon, means coacting between the cap and ferrule for drawing the cap axially of the ferrule in its revolution thereon to close the bottle by draft of the parts respeptively against the mouth and neck flange, and stops for limiting the rotary movement of the cap on the ferrule after disengagement of the grappling sections, from the flange, the ferrule being slitted longitudinally throughout to admit of closure for admission into the cap and passing of the stops to place.
4. A bottle closure oomprisin in combination a screw threaded ferrule or clasping the neck of a bottle provided with yielding grapplin sections independent of the screw threads $01 engaging the shoulder of the neck flange, a closure cap'mounted thereon in screw threaded engagement with the ferrule,-and provided with an annular part i n dependent of the screw threads inclosi-ng the grappling sections, and stops for limiting the movement of the cap on the ferrule after disengagement of the grappling sections from the flange to hold the parts together after removal from the bottle.
5. A bottle closure comprising in combination a ferrule for clasping the neck of abottle provided with yielding grappling sectionsfor engaging the shoulder of the neck flange and screw threaded above the grape pling sections and. a screw threaded closure cap mounted thereon having 'a disk fitted within it for closing the mouth of the bottle, the threads of the respective parts having .terminal shoulders at the ends from which they would part from each other in disengaging the closure from the bottle, whereby the parts are held together when removed from the bottle.-
