IMPROVEMENT IN FRUIT-JARS.

pecification forming part of Letters Patent No. 49,256, dated August 8, 1865.

To all whom 'it' may concern:

Be it known that we, WiLLiAM T. GILLIN- DER and EDWIN BENNETT, of the city and county of Philadelphia, and State of Pennsylvania, have made a new and useful Improvement in Fruit-Jars; and we do hereby declare the following to be a full, clearand exact deferent figures.

-Our improvement consists of a grooved glass cover containing a ringof elastic material, which is pressed down upon and partially around the upper edge of the jar or bottle by means of the screw-cap.

To enable those skilled in this branch of manufacture to construct the same, and to indicate the mode of using the same, we will proceed to describe it.

A is a glass jar or bottle, which is a mere question of shape, and Bis a glass cover, which has an annular groove, C, on its lower face of such a conformation as to have two shoulders, D D, and a central depression, E, which agrees in its diameter with that of the upper projecting edge, F, of the jar. The upper exterior portion of the neck of the jar is provided withthreads G G, whichcorrespond with those in the screw- `cap H. The ring K, ofindia-rubber or other elastic substance, is laid within the groove C, upon the shoulders D D, and spanning the depression E, as shown in Fig. l.

The operation is as follows: The jar being filled with fruit in the proper manner, or to the satisfaction of the operator, the cover, containing the elastic annular pad within its groove, islaid upon the upper edge of the jar, and the screw-cap being placed over and rotated is thereby drawn down with its iiange H upon its cover B, so as to press the latter down and compel the edge F to project the ring into the depression E (see Fig. et) and embrace a portion of the sides of the flange F as well as its top. This makes the packing much more effective, as the bearing is more extensive, and

a leakage from the presence of a small flaw on the upper edge is not so imminent.

The bottle Vis unclosed bylsimply unscrewing the cap H and raising the cover. The general appearance of the jar when closed is neat and tasteful, and they1 may he readily wiped oifto remove the dust in the sale-room or the storeroom of the housewife, as well `as any drip which has fallen upon them in the actof filling. In this respect they contrast favorablywith many wire-and-yoke devices `which are before the people. The elastic pad, when the cover is detached, remains within the groove and does not require special manipulation to place it in 1 position, as the shoulders and sides of the groove are in contact with it, and thus it is prevented from being lost, and great time is saved and accuracy attained by always compelling it to maintain its proper position without special manipulation to t it over the place it is to occupy.

Though not an absolute necessity, we prefer to have the elastic pad occupy the groove in` i the cover from the .shoulders outward, so as to make them come ush with the lower face of the cover, which makes a neat finish, and enables them to be readily wiped'otlbefore being placed in contact with the edibles in thejar.I

Having thus described our invention, we state that we do not claim, broadly, the use of a screw-cap, cover, and elastic ring; but

What we claim herein as new, and desire to secure by Letters Patent, is-

The formation of the groove in the cover,

with shoulders supporting the elastic pad, and with a central depression into whichV the pad is forced by the upper edge of the jar on the downward pressure on the cover by the screwcap, substantially as described.

To the above specification of our improvement in fruit-jars we have signed our names this 29th day of April, 1865. y
