SPECIFICATION forming part of Letters Patent No. 645,430, dated March 13, ieoo.

Application filed September 11 1899. Serial No. 730,132. (No model.)

To azz whom it may concern: retainer; Fig. 8, atop plan of the lid-retainer;

Be it known that I, ANGELINE SMELKER, a Fig. 9, a vertical sectional view illustrating citizen of the United States, residing at North more clearly than in Fig. 2 the form assumed Star, inthe countyof Darke and State of Ohio, in cross -section by the sealing-ring when 5 have invented certain new and useful Impressed down to effect the sealing or closure. 55

. against both sides of the groove.

and against this face the internal surface of the sealing-ring F is forced. A knob cl is provided for lifting the lid from the neck. It will be observed that the junction of the lid and the neck is at the bottom of both sloping faces of the V-groove, so that there is no flat bottom to arrest the sealing-ring.

The sealing-ring F is circular and has sufficient area in cross-section to provide considerable elasticity to compensate for irregularity of the circular faces 0 and E, against which it bears to form the sealing. A circular cross-sectional form is preferable, as shown; but this may be slightly varied, as it would be equally effective were it semicircular, with the circular part undermost in use. It should be made of rubber or of a composition ofsimilarsubstance. Thescrew-ring G is also circular and near the top has an exterior milled groove J, in which a cord or wire clamp may be drawn taut in order to force the ring on and off the neck. The top of the screwring is open, but it has an internal flange H, which extends over the edge of the neck B and downward at the inside of the neck, forming a depressed flange I, adapted to bear upon the sealing-ring F, by which construction the lid is somewhat depressed in the neck, so that the knob d does not protrude above the flange H, which is a convenience when it is desired to set one jar upon another; butit is obvious that the flange II might be adapted to bear upon the sealing-ring with a slight modification in the position of the bearing-faces for the-sealing-ring. Yet the form shown, having a nearly-vertical part between the flange planes H and I, possesses the greatest strength with the minimum thickness or weight of material in the screw-ring, which may suitably be made of either spun or pressed zinc.

In some cases it may be desirable to form either one or both of the faces 0 and E more nearly vertical than shown in order to economize in the use of the elastic material of which the sealing-ring F is formed, and I therefore reserve the right as within the scope of my invention. Also the annular groove, which is formed by the faces 0 and E, may be semicircular in cross-section instead of V-shaped, as preferably formed.

In practical use, the jar being filled, the lid D is inserted, and then the sealing ring F is placed in position in the V-shaped annular groove formed by the oppositely-slopin g faces C and E, and as the groove thus formed may be of greater width at some portions than at others, owing to inaccuracies in forming the parts, as is well known, the-sealing-ring by reason of its large sensitive volume in crosssection readily adapts itself under slight pressure to the variations of surface and approximately forms contact continuously The screw or retaining ring G is placed in posit-ion, and as It is forced against the top of the ring F the latter, having the two annular points of contact below, is prevented from turning, the resistance at the top being slight at first,- so that the metal slides freely upon it until sufficient force is exerted to fiat-ten the top and sides of the ring, as it'would appear in cross-section, so as to resemble atriangle, the bearing-surfaces'thus hemming in the elastic material as it spreads and insuring a tight joint, at the same time preventing an upward movement of the lid. When opening the jar, the retaining or screw ring and the sealingring may he removed and laid away for future use, while the lid maybe conveniently used with the jar while the contents are used in small quantities from it, and thus has advantages appreciated by the housekeeper.

Having thus described my inventiom-what I claim, and desire to secure by Letters Pat= cut, is-

1. A jar-closure comprising a neck pro vided with an internal annular sloping face extending downwardly and inwardly from the top of the neck, so as to form in transverse section substantially one-half of a vertically divided V-shaped groove; a support for a lid at the bottom of the sloping face; a lid provided with an external annular sloping face extending upwardly and inwardly from the bottom of the lid, at the periphery thereof and embracing the whole of the periphery of the lid, so as to form in transverse section substantially one-half of a vertically-divided V shaped groove; a sealingring bearing against both of the sloping faces only at the portions thereof intermediately of their extremities; and a retaining-ring bearing upon the upper side of the sealing-ring; whereby a triple contact-joint is provided.

2. In a jar-closure, the combination of the neck and the lid provided each with an oppositely-disposed sloping face forming onehalf of a V-shaped annular groove parting centrally at the bottom thereof, asupport for the bottom of the lid, a sealing-ring having a contact with the sides of the groove intermediate the tops and bottoms thereof, and the retaining-ring bearing upon the top of the sealing-ring transversely centrally.

3. In a jar-closure,- the combination of the neck having the external lid-securing devices and the internal sloping annular face, the lid-' support, the lid having the sloping peripheral face extending from the bottom of the lid upwardly, the sealing-ring bearing against said sloping faces, the retaining-ring having the securing devices corresponding to the securing devices upon the neck, the parallel portion at the upper part of the neck above such securing devices, the continuous annular groove in the upper part of the retaining-ring registering with said parallel portion and having milling or serrations transversely therein, and the depressed flange removed from such annular groove and bearing upon the top of the sealing-ring in a plane below the top of the neck.

4. In a fruit-jar, a closure comprising the neck and the lid, the annular groove parted centrally at the bottom thereof on a vertical line, a sealing-ring seated against the opposing sides of said groove intermediate of the tops and bottoms thereof only whereby bottom clearance. is effected, and the retainingring bearing upon the upper side of the sealing-ring transversely central thereof, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
