To all whom it may concern:

Be it known that I, Anton 0. Eggers, of the city, comity, and State of New York, have invented certain new and useful Improvements 5 in Stoppers for Rubber Fountains, WaterBottles, &c., of which the following is a specification.

This invention relates to an improved stopper for fountains, for syringes, water-bottles, io and similar articles of rubber, the stopper being designed with a view to facilitate the filling of said fountains or bottles without any spilling of liquid and without removing the stopper from the neck of the fountains or botties; and the invention consists of the combination, with the neck of a rubber fountain or water-bottle, of a re-enforcing sleeve having an interior screw-thread, a funnel-shaped extension above said sleeve, and a hollow screw20 plug fitted into the sleeve and provided with longitudinal slots or openings.

In the accompanying drawings, Figure 1 represents a side elevation, partly in section, of a combined rubber fountain and water-bot25 tie, showing the stopper in closed position.

Fig. 2 is a vertical central section of the neck of the fountain or bottle, showing the stopper in open position, ready for filling the fountain or bottle; and Fig. 3 is a horizontal section 011 30 line x x, Fig. 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a rubber fountain, rubber water-bottle, or other 35 liquid-receptacle made of rubber. The neck B of the fountain or bottle A is provided with an interiorly-threaded re enforcing sleeve, B', and above the sleeve with a funnel, C, by which the fountain or bottle is conveniently 40 filled with water or other suitable liquid. A hollow screw-plug, D, fits into the interiorlythreaded sleeve B' of the neck B, and is provided with longitudinal slots or openings d, which extend from a point at some distance 45 below the top flange, d', of the plug to a point near the lower end of the same, so that when the plug D is screwed entirely into the sleeve B' it closes the fountain or bottle A, so that no liquid can escape. When the plug D is 5c partly unscrewed, as shown in Fig. 2, the slots d extend above the re-enforcing sleeve of the neck B and permit the direct filling of the fountain or bottle.

The fountain A is provided at the lower end with an outlet-tube, e, and a detachable 55 screw-plug, E, which is connected by a chain or other suitable device, e', to the outlet-tube e of the fountain, as shown in Fig. 1. When the fountain is used with a syringe, the bottom plug, E, is removed and the outlet-tube e 60 connected with the tube leading to the syringe. The plug D is then partly opened, so that the slots d of the same serve as vents to permit the running out of the water from the fountain, which would not be the case if the 65 plug were closed. When the fountain is to be used as a water-bottle, it is filled with water, closed at both ends by the plugs D and E, and then used in the regular manner. The neck B is provided with a hanger, f, and the plug 70 E with a ring, e², so that the fountain maybe hung up at either end.

The advantage of my improved construction is that the fountain or bottle can be filled directly by the funnel G and the hollow screw- 75 plug D without removing the latter and without spilling any liquid, as in the fountains heretofore in use, in which an interiorlythreaded cap screws over an exteriorlythreaded sleeve, around which the funnel is 80 arranged. Another advantage is that the funnel extends above the head of the plug, so that the plug is protected against being accidentally turned while the fountain or bottle is in use, which would not be the case if a stop- 85 cock were used in connection with the neck of the fountain or bottle.
