JOSEPH'E. LEMYRE, OF MANCHESTER, NEIV HAMPSHIRE;

PRESERVE-JAR OR COVER TH EREFGR.

SPECIFICATION forming part of Letters Patent No. 638,022, dated November 28, 1899. Application filed May 6, 1899. Serial No. 715,801. (in; model.)

To all whom it may concern:

Be it known that I, JosEPH E. LEMYRE, a citizen of the United States, residing at Manchester, in the county of I-Iillsborough and State of New Hampshire, have invented certain new and useful Improvements in Fre serve-Jars or Covers Therefor; and I do hereby declare the following to be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The covers of preserve jars when sufficiently tight to preserve their contents usually give much trouble to those who have occasion or whose business it is to open them, and those covers which are threaded to the jars are sometimes as difficult to remove as those which fasten with a clamp, while the covers of the so-called vacuumjars re quire to be punctured before they can be removed, and thus they are rendered worthless for future use. To remedy this difficulty, small openings have been formed in the covers of jars and threaded plugs, caps, or spring-valves applied to close them. Such vents have served a good purpose; but the additional expense of applying them is a matter of serious consideration, for the vent, on account of its expensive cap or cover, has cost much more than the jar-covers themselves.

My present invention is the result of much experimental work with a view to venting a jar at as slight expense as possible, by which I have found that much simpler means for closing a vent of this sort will give equally as good results as those which are more expensive and that if the jars are scaled up while their contents are hot a small hole in eithera jar or its cover and above the liquid therein, if covered with a flexible material, will quickly become air-tight by the cooling process of the contents of the jar.

The invention Will be fully set forth in the following specification and claims and clearly illustrated in the drawings accompanying and forming a part of the same, of which- Figure 1 represents the upper portion or neck and cover of a preserve-jar embodying my improvements. Fig. 2 shows the invention as when applied to a cover, Fig. 3 being a plan view of my improved vent-closing band.

To carry my invention into effect, it is desirable to utilize a side opening in either the jar or its cover rather than a top opening, so that it may be closed by a cylindrical instead of a circular band, as the latter form would require a fastening of some sort to prevent its becoming lost.

A represents a portion of a preserve-jar, and B is its cover.

In order that my improved vent-closing band may not become misplaced or lost, I form the vent or perforation a in the groove a, which is usually found in the neck of ordinary preserve-jars, and while an ordinary rubber band would possibly prove sufficient and act as a stopper for the perforation a, a stopper or something thicker than a band and which would extend into said perforation would be more permanently effective. Hence I prefer to provide the inner side of the band C with a boss 0, and this will serve a better purpose if made tapering or conical, as seen in Fig. 3, as it will then more readily engage the perforation. Again, preserve-jars often contain liquids which become more or less gummy when cool, and if the jar were accidentally or intentionally turned so that some of this liquid got into the perforation Ct beneath the band it would be extremely liable to clog the vent. Hence the use of a boss 0 which fills this vent is of advantage in preventing such clogging. This perforation or air-vent being above the level of the liquid therein is a great aid in opening any make of preservejar, no matter what the style of cover may be, as the suction of said cover is at once destroyed the moment my improved band C is moved in a manner to disturb the close fit of its boss 0 within the perforation it enters. In the drawings I show the threaded style of cap which is sealed by being turned down upon a rubber ring D.

In order that people having numbers of preserve-jars on hand may not be forced to buy new ones if desirous of using my improvements, I may provide suitable covers (for various styles of jars) with a perforation b 2 I eaozz formed in the side near the top, as seen in Fig. 2, and, as the equivalent of the groove a, an annular ridge 1) may also be formed on said covers to keep my improved band C from Working off, said band being as Well adapted to close a perforation in the cover of a preserve-jar as one in the jar itself.

Having described my improvements, What I claim isv 1. As a means of venting preserve-jars" and to facilitate opening the same, an annular groove provided with a perforation located above the normal level of the liquid in said jar, and a truly cylindrical band formed of flexible elastic material and adapted to rest within said groove and having a tapering boss adapted to close, enter, and completely fill said perforation.

2. As a means of venting preserve-jars and facilitating opening the same,a cover provided with a side perforation, and a detachable band provided with a boss adapted to enter, fill, and normally close said perforation.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH E. LEMYRE.
