SEALING FRUIT-JARS.

EPECIFIOATION forming part of Letters Patent No. 255,005, dated March 14, 1882.

Application filed January 12, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH MURPHIN, a citizen of the United States, residing in Malaga, Gloucester county, New Jersey, have inventedcertain Improvementsin SealingFruit- Jars, of which the following is a specification.

The object of my invention is to provide a means of sealing fruit-jars without the use of the ordinary devices for securing the cap, and this objectl attain in the manner which i will now proceed to describe, reference being had to the accompanying drawings, in which- Figure 1 represents a sectional view of the upper end ot'thejar, the packingring, and the cap, the latter being removed from the jar; Fig. 2', a similar view, showing the first step in the operation of sealing the jar; and Fig. 3, a view showing thejar sealed.

A is the upper portion of the jar; B, the rubber ring or gasket for sealing the same, and D the cap. Around the mouth of the jar are formed a contracted annular shoulder, a, a shoulder, d, below the same, and a vertical or slightly undercut bearing-surface, b, between the two, and in the cap are formed internal annular shoulders, at and n, and an annular bearing-surface, t7, the radius of the latter be ing. greater than the radius of the annular bearingsurface b on the jar bya little less than the thickness of the ring B.

In sealing thejar the ring B is first applied in the flatwise or horizontal position to the shoulder a of the jar, beyond which the greater portion of said ring projects, as shown in Fig. 1. The cap D is then applied to the ring, the shoulder on of the cap resting upon the outer edge of the projecting portion of said ring, as shown in Fig. 2. Downward pressure is then applied to the cap, the result of this being that the ring B is caused to turn from the flatwise or horizontal position to a vertical or edgewise position, in which it rests upon the shoulder 01, and is compressed and securely confined between the annular bearing-face b of the jar and the corresponding bearing-surface i ofthe cap, as shownin Fig. 3,thusforming a hermetically-sealed joint. The shoulder a of the cap bears upon the upper edge of the ring and serves to prevent in a great measure the access of the contents of the jar to said IlI] g.

In removing the cap it is necessary to tilt the same, as indicated by the arrowin Fig. 3, it being diflicultin fact almost impossible-to remove the cap by a direct upward pull.

While I. prefer to use the shoulders in and n in the cap, these shoulders are not absolutely necessary, and may in some cases be dispensed with, the lower edge of the cap taking the place of the shoulder m.

By my invention I am enabled to overcome both the inconvenience and the expense of ordinary fastenings employing screw rings, clamps, or springs for securing the cap.

I claim as my invention- 1. The combination of the flat annular ring or gasket 13, the jar A, having a contracted annular ring-supporting shoulder, a, and immediately below the same avertical bearing-surface, I), and the cap D, having an internal annular bearing-surface,i, of a radius greater than that of the surface I) by about the thickness of the ring B, and-a shoulder adapted to bear near the outer edge only upon the ringB when the latter is supported in its horizontal position, whereby, on depressing the cap, an abrupt quarter-turn is imparted to the ring and the latter is confined in a vertical position between the bearing-surface b on the jar and the bearing-surfaced in the cap, as set forth.

2. The combination of the flat annular ring or gasket B, the jar A, having a contracted aunular shoulder, a, a shoulder, d, below the same, and between them an annular vertical bearing-surface, b, equal in depth to the width of the ring, and the cap D, having an internal annular bearing-surface,i, exceeding the diameter of the surface b to the extent specified, and a shoulder, m, adapted, when the ring B is supported horizontally, to bear upon said ring near the outer edge only, as set forth.

3. The combination of the'tlat annular ring or gasket B, thejar A, having a contracted annular shoulder, a, and an annular vertical bearing-surface, 1), below the same, and a cap, D, having a shoulder, m, an internal annular bearing-surface, i, and an internal shoulder, confined laterally between the bearings b and to n, the shoulder m being adapted, when the i, as set forth.
