VALVE FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 580,979, dated April 20, 1897. Application filed January 25, 1896. Serial No. 576,794. (No model.)

To all whom t may concern:

Be it known that I, HENRY GERD LOHMAN, a citizen of the United States, and a resident of Mount Vernon, in the county of Vestchester and State of New York, have invented certain new and useful Improvements in Valves for Bottles or other Vessels, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to bottles, jugs, jars, and similar vessels, and the object thereof is .to provide a vessel of this class which having been once filled cannot be emptied of its contents without leaving evidence of the fact, a further object being to provide a bottle or other vessel which is adapted to be filled through the side of the upper portion thereof and which is provided with a neck attachment having a central passage therethrough provided with automatic valves which are so constructed and arranged that they will operate to admit of the discharge of the contents of the vessel and also to prevent the refilling thereof.

The invention is fully disclosed in the following speciiication, of which the accompanying drawings form a part, in which- Figure l is a Central vertical section of the upper part of a bottle provided with my improvement; Fig. 2, a section on the line 2 2 of Fig. l, and Fig. 3 a section on the line 3 3.

In the drawings forming part of this speci-l fication Ihave shown my invention applied to a bottle, and in the practice thereof I provide a bottle or other vesselA, having a neck B, the walls of which are preferably slightly inclined inwardly and downwardly from the top thereof, and the upper end of the neck is closed, as shown at l), and provided with side ports or openings b2. I also provide a plug or stopper O, which is composed of cork cr other preferred material, and through which passes a tubular or hollow attachment D. The attachment D is composed of metal, and formed near the lower end thereof is an annular enlargement d, below which is a contracted valve-seat d2, adapted to receive a valve G, to the lower side of which is secured a rod g, which passes through a keeper or guide g2, secured transversely of the lower end of the attachment, and between said keeper or guide and said valve is a spiral spring g3.

At a predetermined distance above the annular enlargement cl of the attachment D is a contracted annular valve-seat H, on which is placed a valve h, to the lower side of which is secured a rod h2, the lower end of which passes through a spider or keeper h3 and on which is mounted a spiral spring h4, and pivotally connected to the spider or keeper h3 at one side 0f the center thereof is a curved arm or lever K, the lower end of which bears upon the upper side of the valve G between two guides lo, which are best shown in Fig. 2, and the upper end of said arm or lever is provided with an inwardly-directed projection 7c3, which operates in connection with a lug or projection 7a4, formed on the side of the rod h2.

Above the valve-seat H there is a slight annular enlargement in the tubular attachment D, as shown at L, at the upper side of which are formed inwardly-directed plates or projections M, and secured within the upper portion of the tubular attachment D is a vertical plate or projection fm, at the upper edge of which are outwardly-directed prongs or projections m2, and the upper end of the tubular attachment D is provided with a flange or rim m3, which covers the upper end of the plug or stopper O.

It will lbe observed that the upper end of the plug or stopper O is level with the botdevice is secured within the neck of the bottle at the time of its construction and may be secured therein or connected therewith in any desired manner, and I also provide a small port 0r opening O, which is preferably located in the upper end of the bottle or vessel and which is adapted to be sealed by a glass plug or other stopper O2 after the bottle or vessel has been filled, or said port or opening may be sealed or closed in any desired manner, the only object in' this connection being to hermetically close said port or opening so that it cannot be reopened.

The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings.

tom of the side ports or openings b2, and this After the bottle has been filled and the port or opening O sealed, as described, the side ports or openings h2 in the neck may be closed in any desired manner by plugs or Stoppers, or in any other way, and when it is desired to empty the bottle or discharge a portion of its contents said plugs or stoppers are removed and the bottle or vessel is iiiverted or tilted and the valves G and 7L will leave their seats under the pressure of liquids within the bottle and the action of gravity,

and the said liquids will ilow out through the tubular attachment D and out through the side ports or openings h2, or one of them, and this operation may be continued or repeated until the vessel is entirely emptied. It will be understood, of course, that the lower valve G will be the first to leave its seat, and the arm or lever K is operated by this valve in such manner as to withdraw the projection L thereof from its connection with the lug or projection 7Jl on the rod 7b2, after which the valve 7L will also lea-ve its seat under pressure of liquids within the bottle and the operation of gravity, and when the bottle has been emptied or the operation of discharging the contents thereof concluded and the bottle returned to a vertical position the said valves will each be reseated and the lever or arm K will resume the position shown iii Fig. l.

It will be understood that the springs g3 and 7L are contractile springs and serve in the normal position of the bottle to retain the valves in place; but these springs aie so adjusted as to be bai'ely sufficient for this purpose, and the pressure necessary to operate the valves is very slight.

The object of the upwardly and inwardly directed prongs or plates M, the partition m, and the prongs or projections m2 at the top thereof is to prevent the insertion of a tool, wire, or other iiistiiiineiit in an attempt to interfere with the operation of the valves, and it is evident that changes in the construction herein described and modifications thereof may be made without departing from the spirit of my invention or sacrificing its advantages.

I am aware that valves have been devised for the purpose of preventing refilling of bottles after once emptying the saine, but iii these eases two valves were used and connected by a permanent rod or fixture in such a manner that they operate simultaneously, uncovering openings to allow outward passage of liquid, but become firmlyseated when an attempt is made to refill the saine by outward pressure. It is found, however, that by producing a partial vacuum from the outside of the valve after the bottles are emptied the valve can be unseated, and by careful manipulation the bottle can by gradual introduction of liquid be refilled. In my invention this difficulty is entirely obviated, inasmuch as the outer valve when locked cannot be released or raised without first raising the inner valve, and as no vacuum can be produced near the inner valve to raise the first to release the iii-st valve it will readily be seen that said valve cannot be unseated in the manner heretofore adopted.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- I. A bottle or other vessel provided with a neck, the upper end of which is closed and provided with side ports or openings, a plug or stopper secured within said neck below said ports or openings through which passes a tubular or hollow attachment near the lower end of which is a valve-seat, and a valve adapted to be seated thereon, said tubular attaeliineiit being also provided about midway between said valve and the upper end thereof,with an other valve-seat, and a valve seated thereon, each of said valves being provided with a rod, which passes through a keeper or spider, and on which is mounted a spring which operates to retain the valve upon its seat, and a pivoted arm or lever tlielower end of which rests upon the lower valve and the upper end of which is provided with a projection which operates iii connection with a lug or projection formed on the rod connected with the upper valve, substantially as shown and described.
