JAH-CLOSURE AND FASTENEFL SPECIFICATIQN forming part of Letters Patent No. 776,162, dated November 29, 1904.

Application filed August 1| 1904.

To (1J/Z whom t may concern:

Be it known that I, EDWARD ABRAMsoN, a citizen of the United States, residing' in the city and county of San Francisco and State of California, have invented new and useful Improvements in Jar-Closures and Fasteners, of which the following is a specilication.

My invention relates to improvements in Its object is to provide a simple locking means applicable to a variety ot' jars and bottles, but especially to fruit or preserve jars,which fastener can be quickly and easily put on or entirely removed from the jar, which will serve to hold the cover tight, and which will enable the jars to be piled one on top of the other, if desired.

The invention consists ot' the parts and the construction and combination of parts,as hereinafter more fully explained, having reference to the accompanying drawings, in which-q Figure lis a view of the neck of a jar With cover in partial section, showing the fastener applied. Fig. 2 is a plan View of cover and fastener. Fig. 3' is a section ot' the cover'. Fig. i is a perspective view of the fastener.

A represents an ordinary preserve-jar having the outer peripheral annular iiange or ledge 2 proximate to the seat for cover 3. The cover is of glass and with a generally flat top, which latter is preferably concaved centrally, as at 4, for the purpose to be explained hereinafter.

rlhe fastener comprises three parts-the locking bail or lever 5 and the opposing' loops 6 7, made each from a single pieceo'f stiff spring'- wire. The bail or lever 5 is formed by bending the wire upon itself, turning the ends eutwardly to form pintles 8, and looping the side portions adjacent to the pintles to form eyes 9. The loops 6 7 are each made by bending a wire centrally to form a straight horizontal portion l0, which is adapted to engage beneath the ledge 2 et' the jar, then curving the two vertical sides of each loop on either side of the portions l0 to form the hooks 1l, designed especially to extend out around and clear of the ledge and cover, and then bring'- ing the sides of each loop in a plane about at right angles to a plane occupied by portion Y ot' the jar to hold the cover down.

Serial No. 219,042. (No model.)

lO and hook portions ll and providing loop 6 with outwardly-extending end pintles l2 to engage the eyes 9 oi' lever and providing loop 7 with eyes to engage the pintles 8.

In practice the cover is iitted to the jar and the portions 10 oi' the fastener' engaged on opposite sides oiI the jar beneath the ledge 2, the lever 5 being' thrown in such position as to give the greatest expansion to the gripping portions of the loops. VThus when the fastener is in normal relaxed position on the jar, as shown in dotted lines, Fig. l, the vertical spring-hook portions il of the loops are out of contact with the rim of the cover and the ledge, although it will be noted that the portions 10 are sprung in close beneath the ledge. The object of this hooked-spring construction ot' the loops is this: W'hen the lever 5 is thrown over into position indicated in full lines, Fig. l, the radial portions oi. the loops are made to press tig'li'tei'and tighter on top At the same time there is no tendency of the portions l() to slip from beneath the ledge as would be the case it the portions ll were straight, in which latter instance the vertical i portions would act each as a lever iulci'uming' on the cover, and any strain on the parts beyond a certain point would pry the 'fastener loose from the ledge, a contingency not to be desired.

By the" present construction ot' outwardly curving the parts 11 and making them of spring metal they are iliree to draw in as the lever 5 is laid over into the position shown in full lines, and while pressing down on the cover from the top and drawing upon the ledge beneath the parts 'l0 will always remain in engagement with the jar, and a perfect seal is possible. Otherwise expressed, the springhook construction oi' the loops causes the latter to exert a considerable pressure on the cover in a direction at right angles to the cover, but to exert practically no pressure on the cover on lines radial thereto.

The concavity 4: in the cover previously alluded to is to accommodate the pivotal connections ofthe lever and loops by allowing' those connections to be sulliciently depressed to insure stable or permanent locking el" the parts and to bring the top of the locked fastener as near flush with the top of the cover as possible to enable one jar to be stood safely on top of another.

Preferably the lever 5 is extended, so that when lying flat on the cover it will project beyond the perimeter of the cover to give a sufficient finger-hold to enable it easily to be lifted and the fastener disengaged.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with a jar and closure of a fastener comprising a central lever mernber and two opposed spring-hook members pivoted to said lever member, said hook members having means of attachment with the jar and adapted on the operation of the lever to be drawn inward, and to exert a pressure on the cover at right angles to the surface thereof but to exert practically no pressure on the cover on lines radial thereto.

2. The combination with a jar and its closure, of a fastener comprising two wire loops each bent horizontally to provide means of engagement with the jar, and having outwardlycurved vertical portions normally out of engagement with the rim of the cover, and an operating-lever having pivotal means of engagement with said loops.

3. The combination with a jar and its cloi sure, of a fastener comprising two wire loops each bent horizontally to provide means of engagement with the jar, and having outwardlycurved vertical portions normally out of engagement with the rim of the cover, an operating-lever having' pivotal means of engagement with said loops adapted to swing in a vertical plane radial to the cover and to project when in a horizontal position beyond the circumference of the cover.

4. The combination with a jar, of a closure therefor having a relatively flat, centrallyconcaved top, a fastener comprising opposed spring -loops having' means of engagement with the jar proximate to the cover, and an operating-lever pivotally connected with the loops, said loops having outwardly-curved vertical portions intermediate of their points of contact with the jar and the top of the cover, which portions are normally out of contact with the cover.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
