SPECIFICATION forming part of Letters Patent No. 528,260, dated October 30, 18x94. Application filed April 9, 1894. Serial No. 506,795. (No moclel.)

To @ZZ whom t may concern.-

Beit known that I, ADOLPHE RODER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Air-Tight Packages; and I do 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, reference being had to the accompanying drawings, and to the letters of ret'- erence marked thereon, which form part of this specification.

My invention relates to improvements in airtight packings for pickles, pickled meats, fruits and other preserves, and the object of the same is to construct an airtight covering for the receptacles of such, which m'ay easily be removed and partly replaced after opening, so as to keep the pickles and preserves in good condition even after having removed part of the same. I attain these objects in the manner shown on the accompanying drawings, in which- Figure 1 representsa keg provided with the complete covering, one side ofthe ligure showing one half of a vertical section, the other side onehalf of a front view. Fig. 2 represents a jar provided with the complete covering, one side of the gure showing one halt' of a vertical section, the other side one half of a front view. Fig. 3 represents on the left side, one half of a horizontal section on line A-A, (Fig. 2.) with the presser or weight c removed and showing the slits b in the wax orparchment paper sheet b, on the right side one half of the top view of the closed jar. Fig. 4 represents a top view of the presser or weight, indicated by c,in Figs. l and 2, and provided with the holes or perforations c', the number, position, and size of which is not limited. Fig. 5 represents a section on line B-B, (Fig. 3.) ofthe hoop, indicated byf in Figs. l, 2 and 3. Fig. 6 yrepresents a section on line B-B of the muslin, canvas or bladder cover, indicated by e in Figs. 1, 2 and 3. Fig. 7 represents a section on line B-B of the outer wax or parchment paper, indicated by d in Figs. l, 2 and 3. Fig. 8 represents a section on line B-B of the presser or weight, indicated by c in Figs. l and 2, and shown in top view in Fig. 4. Fig. 9 represents a section on line B-'B ofthe inner wax or parchment paper, indicated by bin Figs. l, 2 and 3.

Similar letters refer to similar parts in the various figures onv the drawings.

a. is the keg, with the hoops 'a'.

a" is the jar; b, a pieceof parchment or wax paper, provided with the slits b; c, a presser or weight of wood, porcelain or any other suitable material with the perforations c. a

d is another heavierparchment paper; e, a piece of u'nbleached muslin, canvas or bladder;f, a hoop of wood or metal o r an elastic ring.

The principle is the following: When the receptacle a, a is lled with the pickled meat or preserves, the parchment or wax paper b, well moistened with th'e preserving liquor, is laid on top in such a manner, that the edges shall not project over the top of the presser c. The parchment or Wax paperb has one or more slits b. After the parchment or wax paper b is laid on, the weight or presser c is put in place'and pressed down, until flush with the top of the vessel. This pressure will cause the liquor to rise through the slits in the parchment or wax paper b, and to fill the holes in the presser and the spaces around, thus forming a supply of liquor to replace such as will soak into the meat or preserves. On the top of the presser c is laid another heavier piece d of parchment or wax paper, and on the top of this a piece of muslin, canvas or bladder e, both well moistened and projecting around the rim of the vessel, so as to project under the hoop f when in place. Then the two projecting edges of wax or parchment paper and muslin, canvas or bladder covers, while wet, will be drawn down around the upper edge of the vessel by the hoop or elastic ringf, which then will be drawn tight or driven down tight. of the covers d and e are cut'J even with the lower edge of the hoopf. After this the upper layer, viz: the muslin, canvas or bladder, is covered and made impervious to moisture, by first giving it a coat of thin paste, and

After this the projecting edges when this is dry, one or more coats of -varnish, paint, shellac or solution of rubber. After this the package is ready for labeling and shipment. The appliance of the coating of paste has the purpose of preventing a contact of the varnish or paint through the muslin or canvas With the pickle', which would give the preserves a bad taste.

The advantages Yof this packing are, that the covering is positively airtight on'account of the coating, that the preserves can in no way get any taste from the varnish or paint used, on account of the first coating with paste; that the opening of the package is very much facilitated in comparison to other packings in the market, as it is only necessary to out around the edge of the covers above the hoop, about on line g--g and without removing the hoop, and to lift out the presser c; further that the presser will always act as a weight on the pickles or preserves, when the package is once opened, and will prevent them from drying out.

The packages may be used over and over again, as only the paper and muslin or canvas covers are destroyed, the other parts re maining intact. These covers are appliable to any kind of receptacles, either of wood,

glass, china, metal, porcelain lined or not, and can be applied and removed with ease.

What I claim as new in myinvention, and desire to have secured by Letters Patent, is the following:

The combination of a preserving jar or keg or a similar receptacle with a wax or parchment paper layer b with slits b' a presser c with the holes or perforations c', a Wax or parchment paper layer d, a muslin,canvas or bladder layer e, the latter two being stretched over the edge of the above mentioned receptacle and heldin place by a metallic or Wooden hoop or elastic ringf, drawn or driven tight over the edges of cl and e and around the collar of the above mentioned receptacle, all these forming a cover for the above mentioned v receptacle, coated and made airtight with a coat of paste and one or more coats of paint, varnish or other suitable materia1,all substantially as set forth and described.

In testimonywhereof Iaflix my signature in presence of two witnesses.
