To ALL WHOM fr MAY COOERN: f

Be it'known thatY I, ALEXANDER WARNER, of Williamsburg, (Brooklyn) inthe county of Kings, and State of' New York, have invented a newr and useful Improvement in Means for Closing Vessels for PreservingvFruits and other substances', of whichV the following-,is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, in'whi'ch- Figure 1 represents a vertical section offa preserving-jar, withv its lid or stopper removed, in illustration of my improvement, and I Figures 2 and?) inverted plans, taken through the neckor mouth and stopple of the jar, and showing the relative positions of the'stopple therein, when opened and closed by the turning of the stopple.

Figure 4 represents a vertical section` of a modification of the same, with, in red lines, a means or wrench for closing the jar by the turning ofthe latter or its lid, and

Figures 5 and 6 .top views of the lid and m'outh of the jar, constructed as represented in g.' 4. Similar letters of'ret'ererrce indicate corresponding parts.

My invention consists in giving to the 4jar or vessel, and its lid or stopple, a valvular character, by constructing the stopple with perforations in or through it and the mouth or neck of thejar,and an elastic packing.

or gasket fitting or fitted therein, (if suchigasket be uscd,') with similar perforations, sothat, by simply turning the stopple in its seat, or turning the jaras against thestopple, the necessary vents for exhausting the jar may l be opened or hermetically closed'at pleasure.

Referring, in the iirst instance, to figs. I, 2, and 3, of the drawing, A is a jar, and B its stopple, both of any suitable material. In or through the neck or mouth of thejanis or are one, two, or more perforations, of

any suitable shape, and said neck or mouth, that may be swelled ont for the, purpose, fitted with a rubber or other soft and elastic ait-tight gasket or packing-ring, C, likewise provided with perforations'b, corresponding to those, a, of the jar. The stopple .Bis shaped to it'down within and onor over this packingC, and cupped or hollowed and -provided with side perforations c, corresponding to the perforatons a and b, and so that,'on simply turning the stopple, (which, by`means of the gasket C, forms an ar-tight joint with the mouth of the jan) so as to bring the perforations c in or out of linie with the perforations aand a vent is establishedjfor exhausting the jar, or the same hermeticallyclosed, and which latter may be-done during the `finishing of the preserving or exhausting-process, or as it is completed, with the stopple in the same air-tight lit with therjar or its gasket as when'sa'id .vents were open, whereby-a rapid closing of the jar at the proper time is eii'ectedwith-A out any risk of air rushing in to mar the exhaustion of the jar: -Of course it is immaterial whether thejar or stopple be turned to effect-'the closing. Thejar may be exhausted through the vents formed by theperforations a, b, and c, either by the natural process of boiling the fruit or other substance to be preserved inthe jar, with the stopple litted to it, or by connecting said vents in any suitable manner-with an air-pump for the purpose, and to effect which a wrench .may be used, furnished withtubular prongs arranged to fit the aperture a, and serving alike as arducts or c'ontinuations of the vents, an'd projections or claws to hold' on and facilitate the turning of the jar or its stopplc, to close the vents e, or puttheln outof line with the perforations a and b.

In figs. 4, 5, and' G,`the jar A .has itsapertures a arranged, vertically or otherwise, through a shoulder, s, instead of being disposed latcrallythrough the neck of the jar, .and said shoulder made to receive on, and pref- `erahly more lor Vless-within it, the elastic packing or gasket C, provided with perforations corresponding t0 x the apertures a, while the stopplc B, that lits within the mouth of the jar and on the gasket, has similar apertures, c, so that, as in the othermodilication, on turning the jar or itslid, `to bring'the apertures c in or out of line with the perforations a b, is the jar'opened or closed, so far as its exhausting-vents are concerned.

In g.`4 thereis shown, in red lines, a wrench, as hereinbefore referred to, for closing the jar, and forming continuations to the vents or air-duets for establishing the exhaust, the same being, say, made up of a stock or handle, provided with hollow prongs, arranged to t the apertures Ic, and communicating with a suitableoutside vent in or branch from the stock, that may, if desired, be connected by a iexible'tube'or otherwise with an airl pump, it" exhausting the jar by suction. I f

In some'cases, this gasket C may be dispensed with, and'the lid made to t: and turn directly upon 01 in close'contact with the perforated portion of the jar, so' as to throw the apertures a and c in or out-of line to open and close the jar.

What I claim, and desire to secure by Letters Patent, is-

1. A vessel, with its lid, cover, or stopple, constructed and combined substantiallyes herein described; whereby a. vent is opened'and closed by simply turning the lid,A cover, or' stopple, or the vessel, the one relatively to the other, as herein set forth. I I

2. Likewise, in combinationwith the same, a perforated elstic packing or gasket, interposed between the lid or cover and perforated portion of the jar, substantially. asspecifed. I v p Y 4 ALEXANDER WARNER..
