MATILDA. JANE SI-IUCK, OI BLOOIVIINGTON, ILLINOIS, ASSIGNOR OF ONE-HALF TO PERRY L. NOGGLE, 0F BLOOMINGTON, ILLINOIS.

BOTTLE-STOPPER.

Specification of Letters Patent.

Patented June 29, 1915.

Application filed February 12, 1914. Serial No. 818,405.

To all whom it may concern:

Be it known that I, MATILDA JANE SHUoK, a citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

having for its primary object to provide a suitable stopper which is normally held in a closed position in the bottle neck to close communication therethrough.

A further object of the invention is to associate with the bottle a suitable elastic element which is fixedly engaged with the stop per so as to necessitate holding the stopper beyond the end of the bottle neck in order to dispense the contents of the bottle, the stopper automatically rengaging the neck as soon as pressure is released therefrom.

Other objects as well as the nature, char acteristic features and scope of my invention will be more readily understood from the following description taken in connec' tion with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring to the drawings: Figure 1 is a longitudinal sectional View of a bottle neck and a stopper constructed in accordance with my invention; Fig. 2 is a side elevation of my improved stopper showing its connection with the elastic element and in an outward position allowing the contents of the bottle to be dispensed; Fig. 3 is a bottom plan view of the elastic element used in the present invention, illustrating it in connection with a bottle stopper; and Fig. 4 is a sectional view taken on the line Jrof Fig. 1 and looking in the direction of the arrows.

In the drawings wherein is illustrated the preferred embodiment of this invention a bottle 5 is provided which may be of the ordinary or any desired form and has issuing from the upper end thereof the usual neck 6 which has formed on the terminal thereof a bead 7, said bottle being provided on the inner face adjacent the inner terminal of the neck 6, with an annular groove 8 which opens down into the body of the bottle as shown to advantage in Figs. 1 and 2.

Mounted in the bottle neck 6 is a stopper 9 which is preferably made of glass and has an annular flange 10 formed on its upper This invention relates to bottle stoppers p peripheral edge which engages with the bead 7 when the stopper is in a closed position in the bottle neck. In order to prevent the breaking of the bottle stopper 9 or the neck 6 when the same contact an elastic band 11 is associated with the periphery of the stopper which engages with the inner periphery of the neck 6 when the stopper is in a closed osition.

The stopper 9 is normally retained in a closed position in the bottle neck 6 as shown to advantage in Fig. 1 through the medium of an elastic element 12, the latter in the present instance comprising a resilient rod, one end of which tapers to a point as indicated at 13 and is provided with external screw threads which are engaged with in ternal screw threads'on the interior of the stopper 9, the opposite end thereof being bifurcated and having the branches 14 thereof arcuated so as to normally lie in close proximity to the side of the bottle, the terminals 15 being beveled so as to snugly engage in the annular groove 8 thereby normally exerting pressure on the stopper 9. In order to fixedly engage the threaded shank of the elastic element 12 with the threaded recess of the stopper 9 a suitable adhesive material, such as glue, is applied to the shank and the recess of the stopper thereby preventing the unthreading of the stopper from the screw-threaded shank, it being necessary to rupture the threads on the bottle stopper in order to disengage the same from the bottle neck.

In Fig. 1 a conventional form of stopper retainer is provided as indicated at 1a which in the present instance merely comprises the usual wire strand clasp which engages around the bottle neck subjacent the bead 7 thereof and around the top of the stopper 9 so as to positively retain the stopper snugly in engagement with the bottle neck 6 and preventing its displacement during transportation or the like, a suitable trigger 15 being associated therewith in order to disengage the same from the bottle stopper when so desired.

In reduction to practice, we will assume that the branches of the bifurcation 14: have been engaged in the groove 8 of the bottle which is done by merely thrusting the branches through the bottle neck and allowing them to be engaged with the groove as soon as they have reached the desired point in the bottle neck, said branches engaging the sides of the bottle While passingtherein in View of their resiliencyvwhich normally causes them to expand. When the contents of the bottle is to be dispensed, pressure is exerted on the stopper 9 so as to the flange 10 from engagement With the bead 7 and causing the stopper to be 11D? seated from the necktaking a position as advantageously illustrated in Fig. 2'in' which position the elastic element 12 is under tension so as to automatically reengage the stopper in the bottle neck when pressure is released from the stopper.

It will be understood that the above description and accompanying drawingscomprehend only the general and preferr'ed'embodimentof this invention and that various minor changes in detail of construction,

proportion and arrangement of the parts of the advantages of my, invention.

Having thus fully described my invention, WhatI claim as new and desireto secure by Letters Patent is:-

l. A bottle stopper incombinationwith a bottle having a neck issuing therefrom, a stopper mounted in said neck and'having its outer terminal enlarged to provide an annular flange to engage the free terminal of the bottle neck andtmeans for normally snugly engaging said flange With said neck including a' rod, one end of which is threaded to facilitate engagement With said stopper and the opposite end formed to provide arms; to engage the bottle, substantially as specified. Y

'2.- A bottle stopper in combination with a bottle having the usual neck and provided With a groove adjacent the inner terminal of said'neck, a stopper mountedin said neck, an elastic elementcomprising a resilient rod, oneend of wh ch Washington, 11.10.

is fixedly engaged With said stopper. and the opposite endbifurcated
