F FICEo ATENT i HERMETIC JAR.

SPECIFICATION forming part of Letters Patent No. 298,378, dated May 13, 1884.

Application filed February 27, 1884.

To aZZ whom it may concern.-

Be it known that I, THOMAS HETZLER, of Middletown, in the county of Butler and State of Ohio, have invented a new and useful Improvement in Hermetic Jars, of which the following is a specification.

The object of my invention is to provide a convenient means of sealing jars or cans intended for preserving fruit and other articles. or analogous uses, which shall enable them to be conveniently opened for the purpose of taking out a portion of their contents, and rescaling without the use of new material or apparatus.

In the drawings, Figure 1 represents in perspective a jar made in accordance with my invention, A being the body of the jar, and B the lid. Fig. 2 represents an under view of the lid, and Fig. 3 a cross-section of the same when upright.

I form the lid with a rim of such dimensions as to fit inside the mouth of thejar, and outside of this, and tightly connected to the cover by solder, or in any convenient manner, I form the fillet a, having prongs or projections 0 at intervals on its outer edge. In the recess thus formed I place a string, 12, which may be common twine or other cheap material. poured in while fused, and adhering to the string, as well as packing the recess between the rims as it hardens. For this purpose I use such wax as is commonlyemployed for sealing fruit-cans; but any other composition possessing the requisite qualities of readily fusing under heat and remaining hard at ordinary temperatures may be used. The prongs, which are preferably cut in the same blank as the outer fillet, and left extending outward until the wax is introduced, are then bent over the tvax into the position shown in the drawings, leaving sufficient space between them and the inner rim for the mouth of the can to pass inside of them. The string above referred to serves to unite the wax in a continuous ring and to hold it in the recess when the lid is right side up. It is not necessary The recess is then filled with wax,

(N0 model.)

formed, effectually prevent the wax from fail ing out, and, in combination with the string, insure its being retained in its recess and lifted with the lid when the jar is opened. The heat of the can when the jar is first sealed will ordinarily sufficiently melt the wax to hermetically seal the jar, the lid having simply to be pressed into place. When it is wished to open the jar, it is readily done preferably by a little knocking or gentle pounding about the edges of the lid, though it may be done by applying a slight degree of heat. The lid when lifted will carry with it the band or filling of wax, and when the jar is to be rescaled this can be done by inverting the lid. warming it slightly over a lamp, stove, or gas-jet, or by other convenient means, and repressing it into place; and this can be repeated from time to time, as may be desired, without the use of new materials or special appliances. I

The same mode of fusing the wax may be adopted for sealing in the first instance. The jar and lid may be made oftin or any other suitable material or materials.

Instead of the prongs, a continuous inwardly projecting lip or rim occupying the same position could be used; but this is" undesirable, and the use of the cord which strings together the wax enables it to be held in place by a few such prongs. I have used prongs at intervals of about two inches; but more or less may be used.

I claim as my invention 1. A lid having a circumferential recess packed with a filling of fusible sealing material adhering thereto, and having embedded in said packing a string serving to bind the same together, for the purposes described.

2. A lid having a circumferential recess on its under side, packed with a filling of fusible 90 sealing-material'adhering thereto, and further secured therein by a string embedded in said material, in combination with prongs extending beneath the same, substantially as described.
