JAR.

SPECIFICATION forming part of Letters Patent No. 280,888, dated July 10, 1883.

I Application tiled November 20, 1882. (No model.) 4

T a/ZZ whom it may concern:

Be it known that I, J AMES L. WHEELER, a citizen ofthe United States, residing at Stillwater, in the county of Vashington and State oi' Minnesota, have invented certain neviT and useful Improvements in Jars, of which the following is a specification, reference being had therein to the accompanying drawings.

Thisinvention relates to improvements inl the jars which are used for the preserving of fruit and similar purposes, and which are to be hernietically sealed.

Figure 1 is a vertal section of a jar having my improvements applied thereto. Fig. 2 is a top plan view of the same, and Fig. 3 is a perspective ofthe mouth of the jar. Y

A represents the body of the jar proper, which is usually inade oi' glass, though it may be of earthenware, or of any of the materials used in making these vessels. The neck portion A is formed with a comparatively thick part, A2, in order that it may provide a .support for the rising annular wall af, and also provide a comparatively wide shoulder at B. Upon this shoulder B there is placed an annular rubber gasket, B', which may be of the ordinary character.

C is the cover or closing-piece, having a plain bottom, and of a diameter such as to fit. snugly within the wall a. 'Ihe upper face of the cap-piece lis crowneduthat is to say, the center part of it is highest, the surface sloping down toward the edge from said center portion.'

W represents a fastening-strip of wire, or suitably-shaped piece of metal, it being formed preferably of metal having considerable elas ticity. One end is secured in a small socket or recess, H, formed on the insidefof thewall a. In the same wall, but diametrically opposite to the socket or recess H, there is formed a slot, S, having a vertical portion and a part inclined thereto. The inclined part ofthe slot is made in such shape and so related to the vertical portion that it shall act to hold the end of the holding strip or piece W rmly in place after it has been pressed down upon the cover C. In order to insure a permanentengagement between the holding strip or piece Wr and the walls of the slot S, I form notches or recesses N in the upper side of the inclined part of said slot, into which the end ofthe part W can spring, and which will prevent `lateral disengagement.

The method of sealing the jar with the devices which I have described will be readily understood. It consists in simply placing the cap upon the rubber gasket, and clamping it tightly in place by means of the holding strip W, oneend of which is inserted in the socket or recess I-I, and the other end is then sprung downward in the slot S until it engages with one of the notches, N N, or with the upper wall oi' the inclined part of the slot. At P there is a small aperture through the wall a in the same horizontal plane as that occupied by the gasket. When the cap is secured tightly in place, the gasket insures that the air shall not enterthrough this aperture I, but

when the cap is loosened, the aperturepermits the entrance of air to a sufficient extent to de stroy the vacuum which has been formed below the cover by the hermetieal sealing. As a result, the cap can be easily removed, it not being held upon its seat by the pressure ofthe outside air. The wall a is rounded or swelled, as will be seen, in order to provide suflicient thickness of material outside of the socket or recess H and the slot S.

Ity will be seen that the cover and fastening devices are situated entirely below the upper edge of the neck portion A', said neck part being formed according to the simplest and cheapest method cf making glass jars-that is to say, made with a smooth, plane, or square top; and below' this'smooth, plane edge the fastening-strip and the parts which hold it are situated. In consequence,l I can pack the `jars (both before and after they have been lled with the materials to be preserved therein) with an assurance that there shall be no interference with the fastening devices from outside objects, and the jars can be packed closely and tightly together.

I am aware that metallic cans have been provided with inwardly-projecting shoulders, sockets, removable cover, fastening-strips resting upon the cover, and sockets to hold the fastening-strips; but the articles of this kind with which I am acquainted have had ears or projections extending upwardly from the up per edge of the neck-wall to carry the sockets 2 Y esasss"v .obviate.

tight under Aall circumstances, especially Whenpacking and transporting.

What I claim isl Y l. rlhe combination, With the jar having the inwardly-projecting shoulder, B, to receive a rubber gasket, and the smooth, plane-edged neck-Wall provided with a socket or recess H, and with the angular slot or socket S, having the graduated notches N, of the cover-piece C, crowned upon its upper surface, and an elastic holding-strip adapted to have one end iit in the socket or recess H and the other in said slot S, substantially as set forth. v

2. The combination, With the jar having the inwardly-projecting shoulder B to receive a rubber gasket, and a plane or square `edged neck-Wall, and provided With a socket or rcess, H, extending from the inner surface ofthe neck-wall partially through it, and With the angularslot or socket S, having the. notches N, of the cover-piece C, and the elastic holdingstrip W, adapted to have one end t in the recess or `slotzSand .the :other end in the socket H,1 the Wall at the outer end ofthe socket preventing the holdingstrip. from passing through said Wall, substantially as set forth.

3.4 The combination of the cap or covering,d piece, the elastic strip for holding itin-place,

and ther jar having a plane or square upper edge, having means inside of the neck-wall for securing the cap and the ho1ding-strip, and having its outer surface continuous and unperforated at the points Where the holdingstrip is secured inside, substantially as set forth. In testimony whereof l affix my signature in presence of tvvo Witnesses.
