HERMETIC CLOSURE FOR JARS.

. SPECIFICATION forming part of Letters Patent No. 620,623, dated March 7, 1899.

Application filed November 10, 1898. Serial No. 696,092- (No model.)

T0 at whom it may concern:

Be it known that I, ALFRED L. WEISSEN- THANNER, of New York, State of New York, have invented a new and useful Improvement in Hermetic Olosu res for Jars, which improve-- ment is fully set forth in the following specification. 1

The object of this invention is to furnish a hermetic closure for preserve-jars and other vessels of glass, earthenware, or metal in which articles of food are put up for the market, the closure being one thatcan be effected expeditiously without machinery of any sort, that will securely and hermetically seal the vessel, and that can be easily removed and is capable of reuse.

The invention and its advantages will be fully understood from the following description, in which reference is made to the accompanying drawings, whereof Figure 1 is a vertical section of the neck of a preserve-jar having the closure attached. Fig. 2 is a plan view of the clamping-ring, and Fig. 3 a perspective thereof.

The closure consists of, first, a lid a, of thin pliable metal, such as tin-foil or aluminium, which is placed on top of the jar or vessel; second, a stifier cover B, made of tin-plate or other metal, and, third, a clamping ring, strap, or device 0 for holding the other parts securely in place.

The cover B has a depending flange which is lined with a ring of compressible material I), such as cork or rubber. The cover is placed over the sheet a, of thin metal, pressing it against the rim of the vessel and cansing it to adhere thereto so closely as to make an air-tight joint. This cover is provided on top with one or more air-holes 7t to permit escape of air from between the sheet a and the cover. It has been found that without these holes the imprisoned air would form a cushion, preventing the forcing down of the cover to its proper level. The presence of these airholes is indispensable for covers of small size.

To hold the cover securely in place, which is particularly important in the case ofvessels containing articles which after being sealed up are subjected to a sterilizing process, the clamping-strap c or an equivalent device is furnished. In its preferred form, as shown in the drawings, the strap or ring consists of two parts hinged together by the link d. At one of the meeting ends is a lug e, while the other has a lever or handle f, slotted for the admission of the lug. The latter has a curved or beveled edge, so that in forcing the lever into place the two sides of the ring are clamped tightly against the neck of the bottle. The latter preferably tapers slightly, as shown in Fig. 1. Lug e is perfo rated, and through the perforation is passed a wire g, to which a lead seal it may be attached, whereby removal of the cover cannot be effected without destroying the seal.

The thin metal lid a prevents a contact of the inclosed substance with the compressible lining of the cover. For such substances as do not require sterilization or which will not be injured or contaminated by contact with the lining the lid a may be dispensed with. In this case the cover must not have any perforations.

Having now fully described my said invention, what I claim is 1. A closure for preserving vessels comprising in combination a thin metal lid, a cover having a depending flange around its edge lined with a compressible material, a removable clamping device surrounding the flange and engaging a shoulder on the neck of the receptacle for holding the cover firmly in place, substantially as described.

2. Aclosure for preserving vessels comprising in combination a thin metal lid, a flanged cover having the flange lined with compressible material, said cover being provided with one or more air-holes, and a removable clamp- .ing device surrounding the flange of the cover and holding the latter firmly to the neck of the bottle, substantially as described.

3. The combination with a preserving vessel having a tapering neck, of a closure comprising a thin metal lid, a flanged cover having the flange lined with compressible material, adapted to engage against said tapering neck and the clamping-ring, substantially as described.

4. The combination with the preserving vessel, of the flanged cover having a lining of compressible material, a clamping-strap In testimony whereof I have signed this having on one of its meeting ends a lug, and specification in the presence of two subscrib- 1 0 on the other a slotted lever or handle adapting Witnesses. ed to engage said lug to tighten the strap and draw the cover down tightly against the vessel, and a seal or locking device attached by WVitnesses: means of a perforation in said lug, substan- SIDNEY S. MEYERS, daily as described. HAUER J. ETTRIDGE.
