Description
invited rne-ttt "siedi lling* L. B. OF PHILADELPHIA, PENN SYLVANIA'.
Letters-Patent No. 97 ,293, dated November 30,1869.
IMPROVEMENT IN FRUIT-JARS.
The Schedule referred to in these Letters Patent and making partl of the same To all whom it may concern; v A Be it known that I, L. B. HARBERGER, of the city and county of Philadelphia, and State of Pennsylvania,
have invented 'a new and useful Improvement in Frnit- "the jar, in partial section. l
This invention consists in the provision of inclined grooves in the inner face ofthe neck of the-jar, and in the peculiar construction of across-bar or key, the extremities of which tra-vel in the inclined grooves above referred to, while a projection at its centre presses on the sheet-metal cover of the jar, and locks it in place, at the same time compressing a rubber packing-ring placed beneath.
I will now proceed to describe my 'invention in def tail, as shown in the drawings, in the two figures of which like pants are indicated vby similar letters'of reference.
In the inner face ofthe mouth A, of a fruit-jar, are
l'formed inclined planes or grooves, a a, represented by dotted lines in fig.'1, and by full lines in tig. 2. These grooves can beeasily formed in the process of mannfacturing the jars. v e l At their elevated ends, these grooves terminate in vertical grooves or slots, b b, openV at the top.
`cis a packing-ring of rubber, n 'h ich is placed on a shoulder, d, formed within the neck of the jar, just belowthe grooves a a.
On this ring rests the lid-or cover B, of sheet-metal,
gwhich I prefer to swage into the form shown, or any equivalent form, simply for the piirpose ofpreventing bending under the application of the locking-bar, to be hereinafter described.
It will be seen that the centre ofthe cap B is raised, and that its outer portion is straight all around, where yit comes in contact with the packing.
Thelocking cross-bar C will be 'made in the form described, and will be probably of cast-metal.
This lock consists of arms j' f, which travel in the grooves c a, ears g` g, by`which it is turned', and aprojection, 7a., which, presses on the' centre of the cap B.
The Inode of sealing this fruit-jar must be obvious, from the above description of thedrawings. p
After the jar has been filled,lthe packing is first introduced, then the cap, and finally the locking-bar is fitted in,"itsarms f f entering the glcoves a (t by way -of the slots b b,- after which, by the application of' the thumb and nger, the bar C is turned' as far as desired, vthereby compressing the packing, and securely fastening the cap, and brminga perfectly air-tight joint.
It will be seen that `the projection of the lockingbar serves as'centre or pivot, cn which said bar is.
turned, and, as it presses directly on the centre of the cover, the pressure isequal all around.
I am aware that inclined projections have'been formed'on the upper side of the oever, and the latter is tightened .by means of -a locking-bar, which moves in a circular groove in the neck oi' the jar, so as to ride over the inclined projections, and thereby tighten vthe cover; but in such cases provision must be made to prevent the rotation of the cover. 'Phe'.inventorot such devices states `that he forms lugs on the periphery of the cover, so vthat the latter will remain stationary, and thereby allow the lockingbar to engage with' Vthe inclined projections.
`Should such lugs not exist, the cover will rotate with the bar, and thereby cannot be tightened on the jar; but by my invention, it is limmaterial whether the cover does or does not rotate. locking-'bar :move in theV Ainclined grooves,` and will surely press the coveito its place.
The ears formed on said barare sufficiently elevated toallow a firm hold taken thereon, and the lower projection bears uniformly against the centre of the cover.
I thereby produce a simple and practical invention.
Having thus described my invention,
What I claim as new, and desire to secure by Let.- y
ters Patent, is-
The,1ockingpiece, constructed with ears g g, and the central bearing-projection h, in connection with lthe cover B and the inclined grooves a, in the inner face of the mouth or neck of a jar, substantially as and'for the purposev described. I
-To the above,'I have signed my name, this 28th day of September, 1869.
` L. B. HARBERGER.
