IMPROVEMENT IN, PRESER-VEeCANS.

Specification forming part of Letters Patent No. 28,4 I3, dated May 252, 1860.

To all whom t muy concern.

Be it known that I, THEODO'RE SELLERS, of East Birmingham, in the county of Allegheny and State of `Pennsylvania,fhave invented a new and useful improvement in the mode of hermetically sealipg serving fruit, vegetables, &c. g and I do hereby declare the following to be a full, clear, and

l exact description thereof, reference being had to the annexed drawings, forming part 'of this specication, in which- Figure I represents a vertical section of a fruit-jar with the cap or cover placed on the orifice, but `not pressed down to seal4 the jar. Fig. II is a vertical section of the jar shown in Fig. 1, with the cap or cover pressed down so as to close and hermetically seal it.

In bothiigures like letters of reference are used to denote similar parts.

`My invention is designed to furnish a cheap, simple, andgel'ectual mode of closing fruit-jars, which shall, in ad'dition to a perfect exclusion of the external air, present the advantages of great simplicity and ease vol' application, with protection of the india-rubber or otherrelastic substance used for sealing from exposure to displacement.

Tol enable others skilled in the art to make and use my improvement, I will proceed to describe its construction and operation.

The bottle, jar, or can (marked a) may be d made of glass, stoneware, tin, or other suitable material, and of any convenient shape or size, having a neck, Z), which had better be made slightly tapering upward, although this is not absolutely necessary. About half-way down the neck ofthe bottle lis a groove, c, which surrounds the exterior of the neck, the section of which in the plane of the axis of the jar is a semicircle, or nearly so, as seen in Fig. l. At the mouth of the jar the edge is turnedf outward slightly all around, so as to form another recess or groove around the neck, as seen at e, Fig. 2, which is designed 'to keep the india-rubber` ring from slipping ofi the neck of the bottle or .jar `when the cap is removed. The cap or covering d of the jar is made of the shape of the frustum of a cone,

and maybe made of any suitable material, It is close-.at *the top, and has two annular grooves in its interior, which surround the cover, the section of which in the plane of the axis of the cap is nearly semijars and bottles for pre-y `same distance apart as the grooves c and e in the exterior ofthe neck of the jar. `The lower groove, z', in the inside of the cap d surrounds the edge or bottom of the cap, and the'upper groove, n, isias'far above the groove z' as the groove c in the neck of the iaris below the groove e. The diameter of the cap. is such that when set down over the neck of the jar, with the groove u in the cap opposite to the groove c in the neck of the jar, the cap d shall very nearly touchthe neck of the jar.

The packing which I interpose between the neck of the bottle and the inner surface of the cap to exclude the air is a cylindrical ring, h,

- of india-rubber ongutta-percha, or other suitable elastic substance, the ring being of -such diameter aste lit tightly around the neck of the bottle where its diameter is smallest.

My inode of applying the cap and india rubber te the neck of the bottle or jar constructed as described is as follows: Vhen it is desired to seal up a jar, the india-rubber ring is placed over the neck of the bottle so as to rest in the groove e just below the edge or rim of the neck. TheA cap is then placed over the bottle, with the'inner surface of the neck resting 011 thebuter edge of the indiarubber ring, as seen in Fig. l, just against thev upper edge of the lower groove, z', in the cap.

The groove i is not necessary, however, as the lower edge of the cap may be nished by turning down the edges of the cap, if of tin, so as to strengthen it, care being taken to make the mouth of the cap llarge enough to pass over the india-rubber ring when placed on it. The cap is then pressed evenly down over the neck of the bottle, and as the cap cannot pass over the ring without compressing it, it causes the ring to make a revolution on its axis, passing down with the cap` around the neck of the jar until the groove n in the cap comes opposite to 'the 'groove c in the neck of the jar, when the ring slips into the groove c in the` neck of the jar, and also into the groove n in the inside of the ca 9 `when it expands, so as to fill completely both grooves, as seen in Fig. 2,- so tightly as to form a perfectly air-tight' joint. XVlien in this position, (seen in'Fig. 2,) the cap is kept rmly in though the indiafrubber ring is compressed between the cap and neck of the jar, it is n ot place, because, alf so much compressed as it was immediately before it slipped into the grooves c and n, and

- thus it will require considerable force to raise and the india-rubber ring is thus rolled up the neck of the jar by the pressure of thev cap,

l until it rests in the recess or groove fi around the edge of thencck of the jar, by which it is prevented from being` pulled entirely away "from the jar. 'This is a great advantage, as it avoids the liability of losing the ring, which is `nota1 1 in the way after the jar is opened. l My improvement also possesses a great superiority over those co'ntrivanccs for sealing jars iuwhich the piece of india-rubber used for sealing the jar Vis exposed when the jar is sealed, as by my plan it is entirely protected -by thefcap or cover.

f My improved mode of sealing jars or bot.-

tles ma be used to advantage for other pur poses t an thatlof sealing preserve-jars, as itl is applicable to the orifice of bottles used for medicines,spirits, and volatile fluids, the'readif .nessv with which it may be applied and the. simplicity of its construction rendering it lit-V tle liable to get out of order.

Having thus described my lmprovement in y the mode of .hermetically sealing jars orbottles, what I claim as my invention,'and desire to secure by Letters Patent, is-

The'use of a cylindrical ringv of indiarub; I ber or other elastic material, in combination with and-interposed between the neck of a bottle or jar, and its tap or cover, 'each having a corresponding groove or recess for the reception of the ring, constructed and arrangedsubstantiallyashereinbefore described. In testimony whereof' I, the said THEODORE SELLERS, have hereunto set vmy hand. A
