GeOggH GEORGE H. WOMELSDORF, OF PHILADELPHIA, PENNSYLVANIA.
RING FOR JAR-CLOSURES.
Specification of Letters Patent.
Patented Oct. 19, 1909.
Application filed August 2, 1909. Serial No. 510,825.
To all whom it may concern:
Be it known that I, GEORGE H. WOMELS- DORF, a citizen of the United States, residing in'Philadelphia, Pennsylvania, have invented certain Improvements in Rings for J ar- Closures, of which the following is a specification.
One object of my invention is to provide a packing ring, which vin addition to being capable of effectually sealing the jar or other container with which it is used, shall be rel atively inexpensive to manufacture. These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in Which:
Figure 1, is a vertical section of one form of my improved packing ring; Fig. 2, is a vertical section of a slightly modified form of my invention, and Fig. 3, is a perspective View of the ring shown in Fig. 2.
In carrying out my invention, I provide flat rings of some substance such as wood pulp or straw board which is relatively porous, and by means of suitable dies, form or press these rings into the form illustrated at 1 in Fig. 1, so that they are substantially semi-circular in section. Within the annular container so formed I place a body of paratlin indicated at 2, it being understood that this substance may be applied either by pouring it in a fused condition into the ring or by immersing the ring in a mass of melted paraffin. As a result, the ring itself is saturated with the paraflin.
With a packing ring constituted as described, it is possible to eflectually seal a jar or othercontainer, since when said ring is applied, for example, to a jar of the Mason type, the inner edge of the ring fits between the cover and the neck of the jar, while the lowermost portion of said cover enters the body of paraffin 2.
If, as is usually the case, the jar be heated at the time of the application of the cover, the parafiin is thereby rendered liquid, and when the cover is put into position and the jar sealed, it very completely fills all interstices so as to make a perfect seal.
If desired, I may extend the inner edge of my improved packing ring, as indicated at 3, so that this projects upwardly above the level of the outer edge, forming a relatively extended packing body between the inner surface of the cover and the neck of the jar to which it is applied.
In order that the ring may be capable of fitting jars whose necks vary somewhat in diameter, I may vertically slit this inner edge of the ring as indicated at 4, thereby allowing said ring to accommodate itself as may be necessary.
As is obvious, packing rings made accordingto my invention are relatively inexpensive, since wood pulp in sheet form and paraflin may be conveniently obtained in the open market at prices materially below those asked for packing which contains rubber.
I claim 1. A packing ring made in the form of a container and filled with a sealing material having a relatively low fusing point.
2. A sealing ring made in the form of a container and having a filling of paraffin.
8. A sealing ring made in the form of a container having its inner edge provided with a series of slits.
4:. A sealing ring of substantially semicircular section having its inner edge extended above the level of its outer edge and having its interior filled with paraflin.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
GEORGE H. VVOMELSDORF.
