GUIDO WOIFERMAN, or CHICAGO, ILLINOIS.

BOTTLE-STOPPER.

Application filed August 25,

0 all whom t may concern:

Be it known that I, GUIDO W'OLFERMAN, a citizen of the United States, residing at hicago, in the county of Cook and State of Illinois, have invented a new and Improved Bottle-Stopper, of which the following is a specilication.

y present invention relates to bottle closures and particularly that type of bottle Stoppers designed for being used on milk, soda or other carbonated water bottles, &c., and more especially it has reference to that kind of bottle closure device disclosed in m f copending application, Serial No. 220,518, filed March 5, 1918.

rimarily my present invention has for its purpose to provide a closure device of the general character stated, of a simple and economical construction, and in which the pivotal connections that join the bottle neck clamping member andthe weighted stopper or disk carrying member are of a more simple and positively acting construction, and which makes the use of the spring snaps or catch members required in the construction of the closure device disclosed in my said copending application, unnecessary.

y present improvement in bottle closures embodies certain features of construction and combination of parts pointed out in the following detailed description, specifically stated in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of my invention as applied to the neck portion of a bottle, the parts being at the closure position.

ig. 2 is a similar view, the stopper proper being shown as held to the swung back po sition, while pouring from the bottle.

Fig. 3 is a vertical section of the device taken substantially on the line 3-3 on Fig. 1 and shown as applied to the neck of a milk bottle.

Fig. 4 is an end elevation of the stopper device, looking in the direction of the arrow on Fig. 3.

Fig. 5 is a view similar to Fig. 3 and illustrates a slightly modified form of the stopper or closure member.

Fig. 6 is a similar view of a further modiiication or shape of the stopper.

ig. 7 is a perspective view of my improved stopper device, the stopper portion proper being at the thrust back orelevated position. t

of the blanks from which the neck clamping and the stopper carrying members are formed.

In my present construction of bottle closure, the same comprises, essentially two parts, each part being stamped up or otherwise formed from two spring metal blanks shaped as diagrammatically shown in Fig. 8, one of which A designates the clamp blank and the other, B, the cap or stopper carrying blank.

he clamping blank includes a narrow band-like portion 1, a neck member 10 that extends at right angles to the portion 1 and midway the ends thereof, and which join with another portion, the opposite ends 12`12 of which extend laterally of the neck 10 and in parallelism with the band portion 1.

spring ring 11, the outer or free ends of which are extended as at 11-11it and constitute a convenient means for drawing the rings tightly around the bottle neck and for receiving a tie wire 2, the said ends 11a-11a being notched at the upper and lower edges, as at 3-8, for securely holding the tie wire 2 when the latter is applied.

In my present construction of bottle closure, the neck portion 12 of the blank is of a length, sufficient, when bent at right angles to the clamping ring to extend some distance above the top rim of the bottle to which the device may be applied, the reason for which will presently appear.

That portion of the blank A which includes the ends 12-12 is bent outwardly in a plane parallel with the clamp ring to proe vide for forming vertically extended Opposing bearing ears 41-41 which, in connection with the intervening or base portion 40 of the neck portion 12, constitute a keeper for sustaining the other or cap member of the device.

bent downwardly and constitute the resilient hinge ears 52-52, each of which has an aperture 53 for engaging with a pivot pin 6 that also engages the apertures 7-7 in the bearing ears L)L -Ll.

The extension also includes a heel portion a bent up at right angles and in line with extension 5l, the reason for which will be explained.

The body portion of the blank B, when the parts are bent to shape, as shown, constitutes a stopper carrying disk 55.

In the form shown in Fig. 8, in which the parts are especially designed for use on milk bottles and the like, the stopper includes a weighted member 8 and a yielding or rubber disk 8a, which latter and the weighted member 8 are secured tothe disk 55 by a rivet connection 9, when the stopper is to be used on milk bottles and other like bottles having the internal annular seat. l

The weighted member'8 is formed with an annular undercut groove that tends to bend the rubber disk 8 to fit into the internal groove in the bottle neck and thereby eifect a positive closure of the bottle, when the stopper is at the down or closed position shown in Figs. 1 and 3.

lnstead of forming the disk 8 with an undercut groove, it may be of uniform thick-k ness, when the bottles to which the Stoppers are to be applied have a neck of practically uniform thickness and without an annular groove formed in the bottle neck, as shown in Fig. 3.

1f desired, the rubber disk may be conn caved in cross section for closely fitting down into the annular rim of the bottle necks, as indicated in Fig. 6-

By referring now more particularly to Fig. 4, it will be noticed the ears 4.-4, before referred to, are bent at opposite inclines, while' the ears 52-52 that coengage with the earsV l are bent down at rightangles to the neck or extension 5l and the said ears 52-52 are so spaced, relatively to the ears or bearings 4 4, that when the stopper carrying member is swung out to the open position, thev resilient ears 52-52, engage and wedge between the resilient ears lr-l and thereby provide for holding the stopper carrier to 'the elevated or open position, when it is de-` sired to pour from the bottle, as 'indicated in Fig. 2.

The heel portion o on the extension 51 acts as a stopfor holding the hinged member B from swinging back too far and the said heel portion a also provides a convenient finger manipulated 4means for swinging the stopper carrier to the open position,as the 60 bottle is held in an upright manner, notice the dotted lines on Fig. 3.

Among other advantages developed in my present construction of bottle closureoverI the arrangement of bottle closure shown in my copendmg application before mentioned,

is that, when at the closed position, the stopper portion proper, is located some distance below the hinge or pivot connection with the ears L -l formed on the clamp ring mem ber A, so that the stopper, under ordinary handling of the bottle, when moving it about from one place to another, will not readily rise up from its closure position as is possible when the pivotconncction for the closure member is in substantially the horizontal pla-ne of the closure member, as is the case vin my other construction of stopper' shown and-1 described in the other application referred to.

From the foregoing description taken in connection with the accompanying drawings, it is believed that the complete construction, the advantages thereof and the manner in which my present form of stopper device is used, will be readily apparent to those skilled in the use of devices of this kind.

What 1 claim is:

1. In a bottle closure, a band adapted for engaging around a bottle neck, the said band including a neck portion which extends vertically with respect to the band, the said neck portion terminating in an outwardly extended member disposed at rightangles to the said neck and whose ends terminate in oppositely disposed Vresilient bearings, a weighted stopper carrier, the latter including an upwardly extended neck that merges with an outwardly projected portion, said portion having oppositely disposed resilient ears and means for pivotally securing the said ears within the aforesaid resilient bearings, whereby to frictionally engage and hold the said weighted stopper at its uplifted or open position.

2. 1n a. bottle closure, engaging around a bottle including a neck portion tically with respect to the a band adapted for which extends verband, the said neck portion terminating in an outwardly extend-y ed member disposed at rightangles to the said neck and whose ends terminate in oppositely disposed resilient bearings, a weighted stopper carrier, the latter including an upwardly extended neck that merges with an outwardly projecting portion, said 'portion having oppositely disposed lresilient ears and means for pivotally securing the said ears within the aforesaid resilient bearings, whereby to frictionally engage and hold the said weighted stopper at its uplifted or open position, the upwardly extended portion of the stopper carrier having an upturned heel member for the purposes specified.,

3. 1n a bottle closure, a band adapted for engaging around a bottle neck, the said band including a neck portion which extends vertically with respect to the band, the said neck portion terminating in an outwardly extended member disposed at rightangles to neck, the said band the said neck and whose ends terminate in oppositely disposed resilient bearings, a weighted stopper carrier, the latter including an upwardly extended neck that merges with anoutwardly projected portion7 said portion having oppositely disposed resilient ears and means for pivotally securing the said ears within the aforesaid resilient bearings, whereby to frictionally engage and hold the said weighted stopper at its uplift- 10 ed or open position, the resilient bearings on the band member tapering outwardly, whereby to effect a tight frctonal contact with the ears ofthe stopper carrying member hinged between the said tapering bearings.
