STEPHEN S. NEWTON, OF BINGHAMTON, NEW YORK.

IMPROVEMENT lN BOTTLE-STOPPERS.

Specification forming part of Letters Patent No. 185,694, dated December 26, 1876; application filed October 30, 1876.

' To all whom t may concern.'

Be it known that I, STEPHEN S. NEWTON, of Binghamton, in the county of Broome and State of New York, have invented a new and valuable Improvement in Bottle Stoppers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the saine, reference being had tothe annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical section ot a stopper embracing my invention, and Fig. 2 is a vertical section of a modification thereof. Fig. 3 represents a further modiication.

The same letters indicate like parts in the figures.

A represents a cylindrical plug, of cork or other suitable material, made, by preference, tapering in form, and adapted to fit within the mouth ot' a bottle. B is a tube fitting closely a hole cut for its reception centrally inb the plug A. The outside of the tube B is screwthreaded, in order that it may the better take hold ofthe plug and withdraw it from a bottle, and has a flange or cap, b, attached to its upper end, which llange is, by preference, milled upon its edge to facilitate handling. The interior of tube B is also screw-threaded. as indicated in the drawings, and is provided at its lower end with a valve-seat, b. G is the delivery nozzle or tip, the hole through which (terminates, near its lower end, in a number ot' ports, c. D d is a ball-valve. By preference, I make this valve of rubber, and secure it to the lower end of the screw tip or nozzle O. For this purpose, I sometimes form the lower end of this screwnozzle with a cup shaped cavity, c1, inthe lower end, the mouth of the cavity being somewhat contracted, so that when the rubber ball-valve has been compressed and forced-in position it cannot be readily removed from its proper place, this feature of construction being plainly shown in Fig. 3.

When, however, a metallic ballvalve is used, the lower end of the screw-tip may be slitted, as shown in Fig. 2, so that the prongs or jaws c2 thus formed can be opened a little, the ball inserted, and the jaws then closed, and the ball thereby held in place.

Under soine circumstances I may find it advisable to leave the ball detached, and merely press it upon the valve-seat by screwing down the screw-tip, this construction and arrangement of parts being especially adapted for use when a metal ball-valve is used, because it will insure that the valve shall be properly seated upon the valve-seat b', even though there besome slight imperfection in the construction or operation ot' the parts of the device.

In the construction shown in Figs. 2 and 3 the ball-valve is somewhat smaller' than internal diameter of the tube B. Thus an annular space is left around the valve, through which the liquid can pass freely, and a convenient place for the ports c is made around the neck, by which the ball valve D d is connected with the tip G. This construction also facilitates the application of an outer covering or packing, d, to the inner portion D of the valve. (See Fig. 3.)

What I claim is- The combination of the ti C and ball-valve l) with the plug B, provide With the valveseat b', substantially as set forth.

In testimony that I claim the foregoing I have hereunto subscribed my name in the presence ot' two witnesses.
