SPECIFICATION forming part of Letters Patent No. 616,839, dated December 27, 1898.

Application filed September 27, 1898. Serial No. 692,016. (No model.)

To all whom, it may concern:

VBe it known that I, ANDREW J. HARTMAN, of Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Jars, of which the following is a full, clear, and eXact description.

This invention relates to jars designed especially for the reception-of preserved fruits, and has for its object to provide a jar in which these fruits may be more conveniently contained than in jars as heretofore constructed, and also to provide a closure especially adapted to the jar.

This specification is a disclosure of one form of the invention, While the claims define the -actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a vertical section of the jar. Fig. 2 is a bottom plan view thereof, showing the closure in position to be removed. Fig. 3 is a similar view showing the closure'in iiXed position, and Fig. 4 is an end elevation of the clamping-lever with the plate thereto attached.

The jar has its top a permanently closed, and its lower portion or bottom b is made wider than the top and open, so that the material may be introduced into the jar through the bottom and so also that the opening of the jar will be the largest part of its diameter, thus permitting of filling the jar and removing the fruit without bruising the fruit.

The bottom of the jar is formed with an internal annular shoulder J, said shoulder hav ing a double bevel, producing a continuous ridge or edge, against which is pressed the rub= ber gasket b2. Bearing on the gasket b2 is the closure proper, c, which is a circular or disklike plate having a peripheral flange c', -alsoformed With a double bevel to produce a ridge corresponding with the ridge on the shoulder b. Between these two ridges is pressed the gasket, so as to effect a hermetic connection.

The bottom portion of the jar is provided withtwo segmental slots d and d', such slots opening at the inner surface of the jar outward from the closure proper, c, and being adapted to receive the ends of a clampingplate e, which is disposed transversely of the closure proper, c. The slot CZ is formed with a break d2, running out to the bottom edge of the jar, through which break may be passed one end of the clamping-plate e in the act of placing and displacing the clamping-plate. To place the plate in position, one end is introduced in the slot d, and the other end is moved first through the break d2. Then the plate e is turned on the axis of the jar so as to engage the ends of the plate in the closed portions of the slots d d', as shown in Figs. l and 3. The clamping-plate e has parallel edge flanges e', turned downward thereon. These fianges e' serve to carry pivot-ally the trunnions f of the clamping-lever f', which lever is formed of an integral wire having cam-like bends f2 and having at its end an inwardly-directed U -shaped bend f3, forming a finger-piece by which to manipulate the lever. The anges e at one end of the plate e are bent outward slightly'to form studs f4, which are engaged by the lever f at the points of the bend f3, so that the lever may be held in closed position, as shown by full lines in Figs. l and 3. The closure proper, c, may be provided with a button c2 for permitting the manipulation of the closure. The lever f when thrown into the position shown in Figs. l and 3 turns the cams f2 firmly against the closure proper, c, and clamps the closure in place. shown in Fig. l, the plate e may be freely turned in the slots d d' and removed, which operation may be followed by the removal of the closure proper, c.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-L l. In a jar-closure, the combination of a clof1 sure proper, a clamping-plate having flanges at its edges, the ends of the ianges being bent outward to form engaging studs, and a clamping-lever mounted on the flanges of the clamping-plate, a lever having cams adapted to bear against the closure proper and havel ing at its end an inwardly-directed returnbend, and the lever coacting with the engag- When the lever is thrown bac-k, as

ing studs at the points of said bend, substantially as described.

2. In a jar-closure, the combination of a clamping plate having edge iianges, said flanges being bent outwardly at their ends to form engaging studs, a clamping-lever hav ing two pivots respectively mounted in the flanges and having a cam adjacent to each pivot, the free end of the lever being formed with an inwardlydirected return-bend, and the lever coacting with the engaging studs at the point of said bend, substantially as described 3. In a janelosure, the combination of a clamping-plate having side dan ges, the ends of said fianges being bent outwardly to form engaging studs, and a clamping-lever having Vitnesses:
