W. W. STEWART. Stopper.

No. 234,342. Patented Nov. 9,1880.



SPECIFICATION forming part of Letters Patent No. 234,342, dated November 9, 1880.

Application filed J nly 26, 1880. (No model.) F

To all whom it may concern:

Be it known that l, WVILLIAM W. STEWART, ofBrooklyn, in Kings county, in the State of New York, have invented a new and useful Improvement in Bottle-Stoppers;-and 'I do hereby declare that the following is a full and clear explanation of the same.

This invention is applicable to bottles which.

are designed for transportation with theirliquid contents, such as inkstands, perfume-bottles, 85c.

The common hinged lid with elastic packing is unreliable because uniform action of. the spring cannot be insured, and all ordinary forms of screw and plain stopples compress the air more or less within the receptacle, which tends to force the liquid through joints which otherwise would be tight.

My invention consists in a stopple or cap fitting the inside and outside of the neck of the receptacle and held in place by friction or by a screw or other convenient device, and provided with a vent located at a point where it shall not be closed until the instant before the stopple is home, so that there cannot be any appreciable condensation of the air by the action of the stopple, nor any leakage by reason thereof.

That others may fully understand my invention, I will more particularly describe it with reference to the accompanying drawings, wherein Figure l is a perspective section of my invention. Figs. 2, 3, and 4: represent modifications of my invention without varying its principle.

A is the bottle or receptacle to be stoppered, and b is the ordinary neck to receive the stopple O, which is fitted to both inner and outer side of said neck, as shown in the drawings, and may be secured by a screw-thread, or by friction only, though the former is preferred.

As compared with an ordinary stopple with a given distance of insertion this stopple, fitted to both inner and outer surfaces of the neck, affords double the surface contact and corresponding security against leakage. This is an important consideration, because it implies security with facility of removal.

It is more convenient to make the screwthread on the outer surface of the neck I), and

the same may be cut in the substance of said neck, or may be made upon a separate band to be placed upon said neck and secured there by cement or by other proper means. The end surface of the neck I) is brought to a plane perpendicular to the axis of the screw by grinding or otherwise, so that when the cap is screwed down tight said neck will seat securely upon the packing d, which is placed in the screw-chamber 0 between the inner part, f, and the outer part, g.

The inner part, f, may be made hollow and elastic, as in Fig. 3, or it may be solid and elastic or inelastic, as preferred.

To prevent the compression of air a minute vent-hole, h, is made through the cap (3 into the space cclose to or penetrating through the packing d, but in a place as remote from the inner surface of the neck I) as possible. Through this vent the air within the space 6 may escape while the cap is being screwed down to place, and it is therefore possible to fit the stopple both inside and outside very tightly. Said vent is securely closed by the packing at when the cap is screwed down.

By making a corresponding vent, i, in the inner part, f, of the stopple, compression of the air within the receptacle is also avoided, because as the stopple advances the air will escape through said vents until they are closed by the actual contact of the neck with the packing.

WVhen applied to bottles containing perfumes or other liquids which it is desired to remove in very minute quantities a slight loosening of the stopple will permit the required escape of the liquid in small quantities through the vents.

Having described my invention, what I claim as new is- 1. A bottle-stopple, G, constructed with a space, 6, inclosed between the inner part, f, and the outer part, g, provided with a vent, h, to permit the escape of the air inclosed within said space while the stopple is being forced to place.

2. A bottle-stopple, O, constructed with a space, 0, inclosed between the inner part, f, and the outer part, g, provided with a packin g, d, and vents h i, substantially as set forth.

3. A bottle-stopper, (J, provided with an outer part, 9, the inner surface whereof is prountil said vents are closed, in the manner and vided with a screw-thread fitted to a correfor the purpose set forth.

sponding thread 011 the outer surface of the neck I), and an inner part, f, fitted t0 the in- WILLIAM STEWARL 5 ner surface of said neck, and the vents h z, Witnesses:

whereby the air or liquid inelosed Within the FRED. B. WVATSON,

receptacle may escape in minute quantities JOSEPH M. LAYERS.
