Specification describing certain Improvements in Fruit-Jars,`invented by LEWIS F.

Y Improvement in Fruit-Jars.

My invention consists of a fruit-j ar in which the cap is confined to the jar by a iianged ring,

band Acornpressed'between the ring and the in which the said rubber band is compressed These are main features of my invention, which are toofully described hereafter to need preliminary description.

Figure l is a perspective view of the upper portion of my improved fruit-jar; Fig. 2, a vertical section ofthe same; Fig. 3, a plan view, and Fig. 4, a vertical section of a modication of my invention.

rllhe simplest form of my invention is that itsthe projection b of the cover B, the latter mouth, and this edge and the cover being of being encircled by a rubber band, f, which the lower edge of the band bearing on a shoulder, h, below the mouth of the jar. v After the rubber band has been adjusted to this position a ring, D, o f metal or other suitable material, is placedover all and depressed, and this ring,

above, or, in other words, having a slight taper, when forced downward has a tendency to compress the rubber band against the edge of the cover and mouth of the jar, thereby renof the ringto depress the rubber band is resisted by the shoulder h on the jar. When extent an internal flange, i, `formed at the upper edge of the ring, will bear against the top of the cover and thereby confine the cover, for

the tendency of the rubber is to retain the ring D in the position to which it has been dej pressed, and hence to retain the cover in its position. The ring D, however, and the cover can at any time be removed by a slight eiort. In the modification illustrated in Figs. 1, 2, and 3 the upper edge of the jar, the cover, and

`the rubber band are the same as in Fig. 4; but the ring D', instead of being continuous, is,

split, as shown at so that it can be contracted and made to embrace the rubber band and compress the same tightly against the jar and cover, thereby rendering the joint tight.

This contraction of the ring may be accom-l plished by simple wrappings of cord, or wire, or by other 'devices which will readily suggest themselves; but for reasons rendered apparent hereafter I prefer the contracting'device shown in the drawing, this device consisting of a bail, E, hinged at y y to opposite sides of the contractile ring or band. When elevated this bail perinits the ring to expand and to be readily withdrawn, the bail itself serving as a handle to effect this withdrawal; but after the ring has been again applied to the top of the jar and duringthe depression ofthe bail or handle,

the lower edge of the latter bearing against the inclined upper edge of the ring will contract the same', and when the bail has reached the vposition shown in Fig. l it will retain the position to which it has been depressed, and, at the same time, retain the ring in its contracted condition and the rubber band in its compressed state, thereby effectually sealing the jar and securing the cover until the bail is again elevated. To facilitate the elevation and depression of the bail it may be furnished with a projection, a.

I claim as my invention- 1. A fruit-jar in which a cap is confined to the. jar by'a iianged ring bearing on the cap and compressing a rubber band upon the jar, substantially as described.

2. The combination of a iianged ring, D, having a slight taper, cover B, the rubber band f embracing the top of the jar and edge of the cover, and a shoulder, h, on the jar for retail ing the rubber when the ring D is depressed.

3. The said tapering ring, having an inter-1 'rnN'r OFFICE. l

nal flange, z', so that the ring will serve the twofold purpose of compressing a rubber band and confining` the cover7 as set forth.

4. A fruit-jar in which a rubber ring is caused to embrace the top-of the jar and the edges of the cover by means of a contractile ring or bund7 substantially in the manner described.

5. The combirmtion7 substantially as dcscribed, of the contractile ring or band with a bail7 E.

In testimony whereof I have signed mynamc to this specification in the presence of two subscribing witnesses.
