ar ssa.

To aZZ whom it may concern:

B it known that 1, CHARLES Vv ILLIAM THOMPSON, a citizen of the United States, residing at Quincy, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Fruit Jars, Etc, of which the following .is a spccifica tion.

This invention relates to a receptacle, such as a fruit jar, having an upwardly facing pzu7king-ring seat and a cap having a marginal portion formed to clamp a packing-ring against the seat, clamping pressure being exerted on the cap by toggles, which include inner members hinged to anchoring means on the receptacle, and outer hooked members bearing on the cap, and adapted to exert downward pressure thereon when the toggles are rendered active.

The chief object of the invention is to provide improved means for operatively supporting the toggles on the jar in such manner that the toggles andthe supporting means may be applied to and removed from the jar as a unit.

The invention is embodied in the'impr venients which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification,

Figure 1 is a side elevation of a jar embodying the invention, the cap being removed.

Figure 2 is a vertical section of the jar shown The body of the ar 12 1s preferably tapering or tumbler shaped, and is provided with an annular upwardly facing seat 13 for a packing-ring 1 1. The body has an enlarged cylindrical peripheral portion 15 below the seat 13, and a downwardly facing shoulder 16 below said portion. The cap 17 Specification of Letters Patent. Patented June 2'7, 1922.-

Application filed. November 27, 1920. Serial No. 426,688. 2

has a downwardly facing marginal portion, formed to bear on the packing-ring, and a groove 18 formed to engage the hooked toggle members hereinafter described.

lhe ar is prov ded with cap-confining toggles including inner members 19, having terminal hinge pintle portions 20, and outer members 21 hinged at 22 to the inner members and provided with hooks 23, formed to engage the .cap groove 18. i

{in important element of my invention resides in means employed for operatively supporting the toggles on, the jar, and preferably embodied as the next described.

25 represents a band, preferably of wire, loosely surrounding the jar below the shoulder 16, the function of said band ,being to confine a pair of hinge sockets 26 against the body of the Said sockets engage the terminal pintles-20 to formhinge connections between the toggles and the supporting means, and are provided with eyes 27 embracing'portions of the band 25, lower lugs 28 engaging the shoulder 16 to prevent upward displacement of the hinge sockets 26, and upper confining lugs 29, normally engaging the seat 13, to prevent downward displaoementof the hinge sockets Each of said hinge sockets,its eye 27, and

lugs

28 and 29, is'preferably formed from an elongated flexible metal'strip bent between its ends to form said socket and eye, the end portions of the strip being extended to form the lower lug 28 which is relatively short,

and the upper lug 29 which is longer and is providedwith a hook 29* at its upper end. The arrangement as shown by the drawings, and particularly by Figures 6 and 7 is such that the toggles are adapted to be rendered active, as shown by Figure 7, and thereby exert downward Pressure on the cap, and inactive, as shown by Figure 6, to release the cap. \Vhen the toggles are inactive, the portions of the band 25, embraced by the eyes 27, spring outward 'sufficiently to hold the, hooks 29 in contact with the seat 13. hen the toggles are rendered active the said portions of the band and the lower lugs 28 are pressed inward, the longer lugs 29 being at the same time forced outward or displaced by contact of their lower portions with the enlarged jar portion 15, so that their hooks 29 are removed or displaced'from the packing-ring seat 13, as shown by Figure 7 this displacement oocurring after the toggle members 21 are engaged with the cap, so that the supporting action of the lugs 29 is no longer required. The displacement of the lugs 29 enables the packing-ring 1 1 to contact effectively with the seat 18.

When the toggles are again rendered inactive, the lugs 29 return to the position shown by Figure 6, the form of the hooks 29 being such that they are adapted to enter the crevice between the seat 13 and the packing-ring.

It will be seen that the toggles and the describedsupporting means may be removed as a unit from the jar, ,by springing the lugs 29 outward, and allowing the toggles and supporting means to drop, this being permitted by the tapering form of the jar body.

The inner toggle member 19 may be an elongated loop of resilient wire, including longitudinal portions and curved resilient necks connecting said portions. One of the longitudinal portions forms the terminal hinge pintle member 20, the other longitudinal portion forming the pintle 22 of the hinge connection 22 between the inner and outer toggle members. The curved form of the necks connecting said longitudinal portions renders the member 19 resilient, so that the toggle is variable or conformable to different receptacles and caps, in some of which the distance between the top of the cap and the shoulderlG may be greater or less than in others.

The pintle portion 22" is preferably of"- set from the plane of the toggle member 19, as best shown by Figure 3, this arrangement permitting the said pintle portion to swing inward to the full extent required when the toggle is active. The outer pintle member 21 may be either of open wire construction, as shown by Figure 4;, or may be made of sheet metal. In the latter case, an edge view of said member would be as shown by Figure 3.

I claim: a 1. A jar having in combination, aneupwardly "facing packing-ring seat, a downwardly facing shoulder below said seat, a cap formed to compress a packing-ring on said seat, cap confining toggles provided with terminal hinge pintles, and means for operatively supporting the toggles on the jar, said means including a band loosely surrounding the jar below said shoulder, hinge sockets engaging the said terminal pintles, said sockets being provided with eyes embracing portions of the band, lower confining lugs engaging said shoulder toprevent upward displ cement oi the sockets, and upper confining lugs normally engaging said seat to prevent downward displace ment of the sockets, the arrangement being such that the toggles are adapted to be rendered active, and thereby exert downward pressure on the cap, and inactive to release the cap, the said upper lugs being automatically displaceable from the said seat and from a packing-ring thereon by the operation or? rendering the toggles active.

2. A jar embodying the combination specified by claim 1, the body of the jar being tapered below said shoulder, so that when the said upper lugs are displaced, the said toggles and supporting means may be separated a unit from the jar.

3. A ar embodying the combination specified by claim 1, each of said hinge sockets and its band-embracing eye and confining lugs being formed from an elongated fleX ible metal strip, bent between its end por tions to form said sockets and eye, its end portions being extended to form the said lowerlug, which is relatively short, and the said upper lug, which is longer and is adapted to be displaced outward by the portion of the jar above said shoulder when the accompanying toggle is rendered inactive.

4;. In a jar having a closing cap, a capconfining toggle composed. of an inner and an outer member, said inner member being formed as an elongated loop of resilient wire, including a longitudinal portion which forms a terminal hinge pintle, adapted to engage a hinge socket secured to the jar, another longitudinal portion hinged to the outer toggle member, and curved resilient necksconnecting said longitudinal portions, whereby the toggle is rendered variable.

Tn testimony whereof I have aiiiXed'my signature.
