WILLIAM PAINTER, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE CROWN CORK AND SEAL COMPANY, OF SAME PLACE.

OR STOPPER.-

SPECIFICATION forming .part of Letters Patent No. 528,485, dated October 30,1 894.

Application filed October 8. 1891.

To a/ZZ whom it may concern.:

Be it known that I, WILLIAM PAINTER, of Baltimore, Maryland, have invented certain Improvements in Bottle Seals or Stoppers, of which the following is a specification.

This invention relates to certain improvements in Letters Patent, Nos. 438,709 and 449,822, granted to me, respectively, October 21, 1890, and April 7, 1891, for bottle Stoppers or seals. In the said Letters Patentare shown and described, a bottle seal consisting of a disk cutfrom asheet of some flexible materialsuch as rubber, which in the act of inserting it in the mouth of a bottle is made to assume a concavo-convex f'orm. The said seal is provided with a permanently attached extracting device, and in all cases the extractors pass entirely through the seals and come into contact with the contents of the bottle.

Some objections are raised to the exposure of the metallic extractor to the contents of the bottle; and the object of the present invention is to provide a. bottle seal of concavo-convex form as described in the said Letters Patent, with an extracting deviceanchored within the substance of the seal and not exposed to the contents of the bottle and therefore not open to the objections hereinbefore alluded to.

Vith this in view, the present invention consists in a bottle seal of the above description having an extracting device which consists of a main loop or eye adapted to receive an extracting tool, two additional loops or eyes which are embedded in the substance of the seal, and anchor Wi res whereby the embedded loops are secured within the seal, as will hereinafter fully appear.

In the further description of the said invention which follows, reference is made to the accompanying drawings forming a parthereof, and in which- Figure l is a central sectional view of the upper portion of a bottle provided with the im proved seal. Fig. 2 is asectional view of the seal before its insertion in the bottle'mouth. Fig. 3 is a top view of Fig. 2. Figs. 4 to 11, inclusive, are views of the seal somewhat modified in construction, and hereinafter described.

groove, a, which corresponds in all essential particulars with that shown in the said Letters Patent, and is specially adapted to hold convex by its insertion in the bottle mouth.

Bis the seal which consists as before stated, of a disk out from a sheet of some iexible Inaterial, such as rubber, and faced on the under side with a coating bof some substance which is not affected by the contents of the bottle to which the seal is applied. Y

As described in the said Letters Patent, the seal is made somewhat larger in diameter than the inside of the bottle mouth, and as it is forced into position, it becomes dished or cupped as shown. in Fig. l.

C is a wire loop with its ends turned up. This loop is pressed into the lmaterial of the seal until it nearly reaches the under side which in the operation becomes slightly bulged out. D D are anchors consisting of pieces of wire forced laterally into the seal and through or within the staples formed by turning up the ends of the wire loop. These anchors are entirely within the seal and consequently do not interfere with its compres- ;sion when inserted in the bottle mouth.

By referring to Fig. yl it will be seen that the ends of the staples are thrown inward beyond a vertical line. This bending of the wire is caused by the cupping of the' seal, as will be readily understood.

In Figs. 4 and 5 which are, respectively, a top and a sectional view of a seal, the anchor is formed of a single piece of wire which is bent into the form of a staple and the whole buried in the material of the seal.

In Figs. 6 and 7, which show a section and a top view of a seal, the staple ends of the wire loop are crossed, and anchored by a single wire.

In Figs. 8 and 9 the construction of the Wire loop is a compromise between those shownin Figs. 2 and 6; and two anchor wires are used.

In Figs. l and 1l the staples of the Wire loop are turned inward and in reverse angularpositions and anchored bya single straight IWire.

It will be understood that in all the various forms which are illustrated in the drawings, the broad idea of an anchor wire separate from the loop is maintained; and also that in all the different forms, neither the Wire loop nor the anchor wires are exposed to the action of the contents of the bottle.

In Figs. 1 and 2 the seal is shown as having a thickness or layer, c, of some textile fabric,

situated immediately above the anchor Wires. This arrangement materially strengthens the seal and relieves the same from any tendency to tear as it is drawn from the mouth of the bottle through the medium of vthe loop and a pointed extractor, not shown.

I claim as my inventionl. In a-bottle seal, an extracting attachment which consists of the combination of a main loop or eye adapted to receive an extraciing tool, two additional loops or eyes WILLIAM PAINTER.
