Specification of Letters Patent.

Patented March 6, 1906.

Application 518a May 16,1905, Serial No; 260,388.

In a, whom it may concern:

Be it known that I, EDWARD MANnoNNn'r, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Devices to Prevent Refilling of Bottles, of which the following is a specification.

This invention relates to an improved means or device to be fixed in the neck of a bottle for the purpose of preventing the bottle being refilled after it has been emptied of its original contents, and the same comprises a novel construction and combination of shell or hollow plug adapted to close the passage tlrrough the neck of the bottle, a

ravity-valve controllin the port or o ening inthe bottom of the she I, and means or fixing the shell in the neck of the bottle, all as hereinafter fully described, and pointed out in the claims at the end of this specification.

The combination and operation of my said device will be explained with reference to the accompanying drawings, in which- Figure 1 represents m device fixed in place in the neck of a bott e, the body of the device and the neck of the bottle being shown in section. Fig. 2 is an exterior View of the device before it is placed in the bottle, showing the lower portion of the outer wall and also the valve and its seat part1 in section. Fig. 3 is a transverse section ta en diametrically through the shell above the valve and showing the valve closed on its seat. Fig. 4 is a transverse section taken through the shell on the line 4 4, Fig. 1. Figs. 3 and 4 are represented on an enlarged scale.

The part A, which I have termed the shell, is made in two arts a a inclosing a chamber as, having su stantially the same dimensions diametrically as the neck of the bottle, but sufficiently small to fit closely into the neck when inserted through the mouth. Above that ortion a which fits into the neck the shell is enlarged diametricall to reduce the chamber a, and on this en ar e end is fixed the cap or top piece a by a ap-joint a. The shoulder b, which is formed by the increase in the diameter of the up or part a over the body a extends over an rests on the top rim around the mouth of the bottle, and a rubberwasher or other packing (indicated at d, Fig. 1) is placed between the two surfaces to make a tight joint all around the rim.

In the lower end of the shell a", which is of the same diameter throughout, is a valveseat 0, provided with a flat to )face and of circular outline for a valve 0 the flap kind. The valve has a cup-she. ed or hemispherical body f of approximate y the same dimensions diametrically as the opening in the bottom of the shell and a fiat rim f around the circumference to project over and make a close joint with the valve-seat (2 when closed on it. This last-named part is best formed of a separate rin rovided with an external groove h, into w nch the wall of the shell a is forced after the rin is set in place, as seen in Fig. 1 and the va vef being attached to the ring by a hinge g the ring is inserted and permanently fixed by crim in the outer shell into the groove 71.. The mm of the valve and its position when closed on its seat are seen in Fi s. 1 and 2. Its position when the bottle is tipped to pour the liquid is indicated by the dotted lines in Fig. 1.

In the enlarged chamber a" above the neck a stationary uard permanently fixed to the walls of the chamber rotects the valve from being tampered with om the outside.

A protector of some kind is required to revent the valve being reached and held 0 its seat by introducing a wire or other instrument through the mouth of the bottle, and in the present device the means provided for that purpose is constructed with a view to afford the necessary rotection without materially afiecting the ca outflow of the liquid. This art is composed of several conical rings m of ifi'erent diameters placed concentrical y one within another and fixed in that position by means of crossrods 1), extending diametrically through the conical rings at right angles to each other, and from one side to the other of the surroundin shell to the sides of which the rods are fixed. The conical rings are so arranged one within the other that the u per ed e of each ring will overlap the lower edge of t e ring lying next within it, and the space separating each ring and the next is necessari y inclined outwardly or toward the side wall of the chamber (1. instead of erpendicularly downward. The efl ect of t 's construction is to revent the introduction of a wire throu h t e mouth or outlet into the valve-chain er o while not interfering with or materially reducing the area of the discharge.

In the top of the cap-piece a an outlet 8 is provided for the discharge of the li uid, and a spout or neck 1*. surrounds the out et to receive a cork w for closing and sealing the bottle. This neck is spun or otherwise formed integrally with the cap-piece to reduce the number of joints.

The means for fixing the plug in place should be such that the device cannot be removed without destroying it or breaking the bottle, and at the same time it must be readily applied without increasing the expense or requiring much exercise of Sklll or labor. The fastening means for this purpose (illustrated in Figs. 1 and 2) is self-acting in its character and consists of spring-catches attached to the inside of the shell a and pro'ecting through apertures in the walls of the s ell, so as to enga e notches or shoulders Z, formed in the wa l of the neck of the bottle just below the top rim. Each catch is composed of a sprin tongue y, attached at one end to the wa l of the part a on the inside and rovided with a short bolt or spur y on the ee end. This last-named part sits through an a er ture in the shell a at proper distance be ow the shoulder b, so that the catch will engage the notch 2 in the neck when the shell being pressed down into the bottle comes to a seat on the top rim of the neck. As these fastenings are not accessible from the outside after the device is inserted and fixed in the bottle, it can be removed only by destroying either the device itself or breakin the bottle.

A wire-gauze strainer X is sometimes fixed in the chamber a below the guard m to exclude dust and insects.

. opening, and a Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a device for preventing refilling of a bottle, a shell having a cylindrical body portion to fit into the neck of the bottle and a head of greater diameter than the mouth of the bottle to rest on and cover it and provided with an opening in the bottom of the body ortion, a valve-seat around said opening, a liinged upwardly-o ening valve having a cupshaped body and a ange to fit the valve-seat, the top of the shell being rovided with an outlet-opening, and means or fixing the shell in the neck of the bottle.

.2. The combination withabottle,'of a shell fixed in the neck thereof having an enlarged top adapted to seat on the rim and close the mouth of the bottle and a body ortion extending into the assage throug the neck and provided Wit an opening in the lower end, a valve-seat around said opening, a hinged valve seated thereon and opening upwardly therefrom, the shell having an opening in the top and a standing rim around said uard fixed Within the shell between the sai opening and the valve.

In testimony whereof I have hereunto set my name to this specification in the presence of two subscribing witnesses.
