SPECIFICATION forming part of Letters, Patent No. 781,526, dated January 31, 1905,

Application flied May la, 19o/1.* seriai No. 207,741.

To all whom t may con/cern.-

Beit known that we, THOMAS H. IvEY and JOHN GEORGE BECK, citizens of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Non- Refillable-Bottle Stoppers, of which the following is a specification.

One object of our invention is to provide a device for preventing the relillingof a bottle with liquid after it has once been emptied which shall be of simpler and less expensive cmstruction than similar devices of the same c ass.

More particularly the object of o ur invention is to improve, simplify, and cheapen the construction of the device for which Letters Patent No. 687,236 were granted to us on November 26, 1901.

l invention.

t cated at a.)

In the above drawings,A illustrates` a portion of a bottlerwhose main portion'is of the ordinary construction, but whose neck is provided with an internal annular recess, (indi- In the lowermost portion of said neck we retain a bushing, preferably of por- -celain or glass, by means of. a washer or packing ,which is compressed betweensaid bushing and the inside of the neck. There is preferably a ange 62 on the bushing Z) for the purpose of engaging the washer and there is within said bushing a tubular guideway b3, held by means of webs b'so as to be concentric with the flange, and consequently with the neck of the bottle. y

A valve B, whichv also serves the purpose of a float, is normally held seated upon the upper end of the bushing by means of a the bushing o.

weight b, preferably in the form of a ball, attached to itby means of a flexible connection o6. In order that the valve B shall be v properly guided to its seat, we provide a tubularl stem 57, fixed concentrically within it and designedto enter the tubular guideway b3 of In order to lessen the friction betweenthis spindle and the sides of the guide- Way, We form this latter of a corrugated or ribbed section, as indicated in Fig. 4, so that there will be but a minimum bearing-surface between it and the spindle. The flexible connection b preferably passes through the spindle, which is countersunk in the valve and slightly enlarged or headed, so as to be permanently retained in position. If a silk cord, for example, be employed as the exible connection, thiswill be knotted or cemented at its upper end and the head of the spindle 57 will be covered by a plug Zus of the same material as that of the valve, usuallycork.

In order to prevent the valve being tampered with, we provide a molded piece C, of

porcelain or glass, which may be described as l a tubular bushing provided lwith a coveringhood c, supported a short distance above itsv end by means of lugs c.

.ing material, such kas cork, is fitted onto the lower end ofthe bushing C, so as to prevent the passage of liquid Ato the Vspring c2, as well as to hold said bushing tightly in place. f This ring c2 is preferably formed of a wire of spring material formed in Va number of corrugations and bent into circular form.

Under ordinary'conditions the valve B remains seated on the upper end of the bushing b, and when the bottle is inclined, as shown in Fig. 2, it is permitted to move away from said The said bushing C seat to a limited extent to permit the outflow of liquid from the bottle. The flexible connection L is made of such a length, however, that the weight 65 by catching upon the inner end of the bushing holds the valve 'from moving more than about one-quarter 'of an inch away from its seat. rlhis, however, is amply suiiicient to permit liquid to freely flow out of the bottle. It' it beattempted to refill the bottle, the entrance of the liquid into the neck of the same will, if the neck end of the bottle be inclined below the horizontal, float the valve B to its seat-upon the end of the bushing b. In all other positions the weight L will forcibly hold the valve to its seat.

Owing to the small friction between the spindle 57 and the tubular guide 3 of the bushing Z), the valve B is free to rise with the rise of liquid and be firmly seated upon the end of the bushing Z), so as to prevent the entrance of liquid into the bottle.

We claim as our invention- 1. The combination with a bottle ot' a bushing held in the neck of the same, a centrallysu pported guideway in said bushing, a valve constructed to seat on the bushing and having a stein operative in said guideway, with a weight normally tending to keep the valve seated and a flexible connection between the valve-stem and the weight, substantially as described.

2. The combination with a bottle having a valve-seat in its neck, of a valve constructed to engage said seat, a tubular spindle attached to the valve, a guideway for said spindle, a flexible connection extending through thel spindle and a weight attached to said connection, substantially as described.

3. The combination with a bottle having a valve-seat and a guideway in its neck, of a valve of material capable olE floating, placed to engage said seat, a tubular spindle lixed to said valve and engaging the guideway, a weight, and a flexible connection passing through the spindle and connecting the weight and the valve. substantially as described.

4. The combination with a bottle, of a Hanged bushing in the neck thereof, a washer between said bushing and the neck, a substantially cylindrical float-valve having a tubular spindle attached to it, a tubular guidewayin the bushing for said spindle, a \\'eight, and aexible connection passing through the spindle and attached to the valve and said weight, substantially as described.

5. rlhe combination with a bottle having in its neck a valve-seat and a ribbed guidewagg', a l'loatable valve for said seat having a spindle operative in said guideway, with a weight and a flexible connection between the valve and said weight, substantially as described.

ln testimony whereof we have signed our names to this specification in the presence ol two subscribing witnesses.
