J. MAUDERER. STOPPER.

APPLICATION FILED AUG-2B, I9I5.

Patented Sept. 5, 1916.

JOSEPH MAUDERER, OF NEW YORK, N. Y.

STOPPEB.

Application fi1ed August 28, 1915.

To all whom it may concern Be it known that I, J osnrrr Marmnaua, a citizen of the United States, and a resident of the borough of the Bronx, county of the Bronx, city and State of New York, have invented certain new and useful Improvements in Stoppers, of which the following is a specification.

This invention relates to stoppers, and has for its object to provide an improved stopper which will supplant to a large extent the stoppers made of rubber or cork, as now generally used.

For this purpose the invention consists of an improved stopper consisting of cotton saturated with gelatin and kaolin, and also saturated with paraffin, and the invention consists further of the improved Drocess of making such stoppers.

In the accompanying drawings, Figure 1 shows a sectional side view of a mold in which the stoppers are formed, and showing the cotton being fed to a rapidly rotating spindle; Fig. 2 shows a similar view with the cotton fed around the spindle or pins until the mold is filled; Fig. 3 shows a similar view with the cotton filling the mold, but with the spindle withdrawn, and shows the stopper itself ready to be withdrawn from the mold; Fig. 4: shows a side view of a completed stopper; Fig. 5 shows a plan view thereof; Fig. 6 shows a side view of a smaller sized stopper; Fig. 7 shows a plan view thereof; and Fig. 8 shows a stopper wound around a wire formed into a loop so as to permit the ready removal of stoppers from bottles and the like.

Similar reference numerals indicate corresponding parts throughout the various views.

Referring to the drawings, and more particularly to Fig. 1, the mold 10 is provided with an opening 11 through which a pin or spindle 12 passes. The spindle 12 is rapidly rotated about two thousand revolutions per minute, and during its rapid rotation, the cotton is fed in the direction of the arrow 13 toward the spindle. This cotton is saturated with gelatin and kaolin, and

brings the cotton into a yieldable mass which, on the rotation of the spindle, causes the cotton to be moved with the spindle and subjected to centrifugal forces, and by that and the rapid rotation, the cotton is formed into various layers tightly contacting with each other.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Serial No. 47,762.

in Fig. 2 is shown the cotton around the spindle so as to fill the mold, which mold has a configuration similar to the form which it is desired that the completed stopper should have, and, similarly, in Fig. 3,

this mold is filled and has the spindle withdrawn, whereby the cotton now formed into a stopper, shaped by the mold, is in a positlon whereby it may be readily taken out. After the thus-prepared stopper is taken out of the mold, it is placed into a baking oven at moderate heat, which causes the gelatin and kaolin to dry and the various layers of molecules of the cotton to be tightly compacted. After the stoppers are thus dried, and while still warm, they are inserted into a hot parafiin bath heated to 1&0", in which is mixed white rosin, and the paraffin enters into the interstices of the cotton and fills them up, thereby making the prepared cotton stopper impervious to moisture and liquids. Of course, the molds or forms can be shaped into any shape or sizes, and stoppers can thus be produced of any sizes, as desired. If it is desired to provide a stopper with a handle whereby it may be readily withdrawn from a bottle, a wire is arranged to have its ends parallel with each other, and the cotton is wound around and forced against this wire core by the rotating and centrifugal actions, and thereby becomes an integral part of the stopper. Such parallel wires are indicated by 15 and 16 in Fig. 8, and they are formed into a loop 18 which may be readily inanipulated by the user of the stoppers.

By my improved invention, a very satis factory substitute is Provided for the present stoppers of cork and rubber, and a very sanitary and useful article is provided, which is absolutely air-proof and liquidtight.

As cotton in its natural form is the nearest product to the cork wood, it, when compounded as described above, answers the same purpose in every instance, and as the various sized molds lend themselves readily to the production of any shape or size of stopper, a useful article is produced. As the specific weight of the finished article is about the same as that of the cork stopper, the same advantages follow its use. Such an article when manufactured will not alone be a great benefit to the public in general, but also to the cotton planters, and a new market will be created for that product.

ers of cotton saturated With gelatin and kaolin, dried and paraffined, and a stem embedded therein.

In testimony that I claim the foregoing 1-5 as my invention, I have signed my name in presence of two subscribing Witnesses.
