ALBERNE ll. BURDIOK, OF DUNELLEN, NEW JERSEY.,

FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 681,871, dated september s, 190'1.

' Application filed May 21. 1901. Serial No. 61,209. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, ALBEENE H. BURDICK, of Dunellen, Middlesex county, State of New Jersey,have invented Improvements in Fruit- Jars, of which the following isa specication.

My invention relates to fruit-jars having a close-fitting cover and provided with means for forcing said cover to its seat and removably securing the cover to the jar in a manner to seal the contents of the jar from the surrounding atmosphere, doing so in a way` that is more advantageous than has heretofore been accomplished.

My invention consists, primarily, in the employment of a channeled cover provided with a yielding gasket and adapted to rest upon the top of the jar to be closed and to enter slightly into the mouth of the jar, the said cover being held securely in place by a suitable spring-fastenin g which locks beneath a beveled month-fiange when forced downward, and a vent in said cover that is closed by an elastic member which is portable with said spring, the whole arranged and operating substantially as hereinafter described.

My invention further consists in certain combinations and subcombinations to be hereinafter described.

In the accompanying drawings, Figure l shows a jar and its cover thereon arranged according to my invention. Fig. 2 is a plan view of the cover and spring-fastening for securing the cover shown in dotted lines. Fig. 3 is a view in elevation of a cross-section of the lid or cover of the jar, and Fig. 4t shows a detail of construction of the springfastening.

Referring to Fig. 1, there is shown a jar A, having a mouth-liange B, that is beveled to present an inclined plane to the applied spring-fastening S when the said spring is pressed into position to secure the lid-upon the jar for the purpose of forcing open the spring ends and admit of their properly interlocking beneath the flange at j j to hold irmly. The cover C, shown in cross-section, is channeled to receive the rubber gasket g and is provided with the lip Z, that sets down into the mouth of the jar A and guides said cover into its proper location upon the mouth of the jar. By employing a jar which has 'a mouth edge which is smooth, as on glass tumblers, a perfectly air tight joint can be formed by the employment of such a cover. A vent o is shown in cover C,that is normally held closed by the rubber band r b, that is slipped onto the spring-fastener S and is held pressed to cover the said vent by the said spring when the saine is in position to secure the cover to its seat upon the mouth of the jar and to open said Vent when the said spring is removed in opening the jar. The advantage of employing an elastic band supported upon the spring-fastener of fruit-jars is that they can be renewed at slight expense and result in the employment of new bands in the relling of jars and when used are properly disposed in the assembling 0f the parts Without a liability of omission, being in full view, and unlike a covered stopper that would be concealed if used and which would be liable to be left out in the assembling and its failure to be used would not be seen, and the object .for which the jar is used would thus be defeated. The spring fastening device S comprises a spring-strap-like member curved in the center Where the rubber band 1 b is affixed and provided to receive the said band. It is so formed as to require that its ends shall spring apart when it is forced down over the mouth-flange B and to catch under the abrupt edge of said flange. The terminals of the spring ,S`are each cut in to provide for turning the two points t' t' to serve as the catch and leaving a point p at each terminal that can be used for unlocking the fastened spring when it is desired to open the can. This is accomplished by forcing the end of the spring S outward on one side of the mouth-iiange by the thumb or by a tool or a knife-blade, when the spring is released, carrying with it the rubber band which closed the vente and leaving the cover C free to be lifted off from its seat over the mouth of the jar. There is an advantage in employing the two points 7l e' on each terminal of the spring.

S, as a better bearing is in this way provided as compared with the use of a single point for a bearing under the edge of the mouth-flange, and by the means of the point p the releasing of the spring S from being caught under the flange B is greatly facilitated. The cover C is provided with two lugs ff, between which the spring-fastener S rests more securely.

ICO

These lugs are formed with the cover when the tovrest upon the rim of the mouth thereof, an f elastic gasket between saidcover and said jar, alip on said cover enteringinto the mouth of the jar, a vent in said cover; a spring-fastener for securing said cover `to its'seat that comprises a depressed portion carrying an elastic band for closing said vent, and .provided with tWo bearing members adapted to catch under the abrupt edge on the mouthflange of said jar,at either terminal, and the projecting point p on either terminal of said spring for facilitating the removal of said interiocked spring.
