Description
Original Filed July 11, 1931 [N VENTOR JOHN A. Gamma-7'51? TTORNE Y Patented Mar. 10, 1936 UNITED STATES PATENT OFFICE mrrnn RUBBER ARTICLES Original application July 11, 1931, Serial No.
550,165. Divided and this application Septemher '1, 1934, Serial No.743,086
8 Claims.
The invention disclosed in this application, re-- lates to dipped rubber articles, which application is a division of applicants co-pending application #550,165 filed July 11, 1931, now Patent No. 2,015,648, granted Sept. 24, 1935.
One of the purposes of the invention is to provide an improved dipped rubber article having.
.20 a hollow rubber article having an opening therein, the margin of the article at said opening being reinforced by a stream-lined accumulation of the material and having a feather edge.
A further purpose of the invention is to provide an improved protector of the character described.
The foregoing and other purposes of the invention will appear from the detailed description and claims when taken with the drawing in which Fig. 1 is an elevation of a stocking protector embodying the invention; Fig. 2 is a view of the upper end of the stocking protector as shown in Fig. 1; Fig. 3 is a plan view of a patch to be applied to the stocking protector in accordance with the invention; Fig. 4 is a sectional view of the protector taken substantially on the line 4-4 of Fig. 1; Fig. 4A is an enlarged sectional view of the reinforcement as shown in Fig. 4;
Fig. 5 is a sectional view of the protector taken substantially on the line 5-5 of Fig. 1.
Referring to the drawing, l0 generally designates a stocking protector of rubber or the like, made by dipping a form of the character disclosed in the mentioned co-pending application into liquid rubber such as an aqueous dispersion of rubber or a rubber solution, and then properly curing and treating the deposited coating forming the protector. It is necessary only to mention that the liquid rubber may contain the usual vulcanizing material, accelerators and other ingredients including pigments to produce goods of the desired quality and color. The protector l0 has the general shape of a stocking, except that the heel portion l2 and the toe portion l3 each has an opening therein. The margin of Another purpose of the invention is to provide the opening in the top of the protector is reinforced against tearing in any suitable manner. As herein disclosed, the reinforcement is shown in the form of a bead or a ring-roll [4. The protector in its preferred form, comprises a plurality 5 of coatings deposited on the form by successive dippings and in order to reinforce the heel portion of the protector, a reinforcing patch I5 is provided as illustrated in Fig. 3. This patch is preferably applied between the several coatings 1 of'the deposited rubber so that it becomes embedded therein. For example, if the stocking protector comprises four coatings, the patch I5 is applied between the second and third coatings as indicated in Fig. 5, wherein the first coating 15 is designated "A, the second -B, the third 0 and the fourth D. It is to be understood however, that the laminations indicated in Fig. 5 are not apparent in the deposited rubber stocking protector since the several coatings form a substantially homogeneous mass. The opening in the heel portion of the protector has a reinforced margin l6 preferably in the form of a bead or a ring-roll. It will be noted that the lower portion of the patch l5 as shown in Fig. 1 engages the heel bead l6 so that there will be no weak area in the protector between the patch and this head, thereby preventing the tearing of the stocking protector at this point as it is drawn over the foot. 30
The opening in the toe portion of the protector has its margin strengthened by a reinforcing ridge ll on one surface of the margin. This ridge as best shown in Fig. 8 has a feather, megascopically jagged, line edge l8 and has a' 35 cross section that is semi-oval or semi-pear shaped. It will be understood that the contour of the reinforcing ridge is caused by the action of the force of gravity in conjunction with the shape of the form on which the article is made since the liquid rubber in addition to coating the form when dipped therein and then removed, accumulates by drainage to develop the ridge in the article at the toe portion of the form.
While a stocking protectorhas been disclosed by way of example, the invention is not limited to this particular article, but is applicable to any dipped article having a reinforced edge and particularly to a hollow article having an opening therein, the margin of the material at said opening being reinforced.
The expression feather edge as herein used is defined as a very thin or beveled edge. (Funk 8; Wagn'alls Standard Dictionary Edition 1926, page 904.) The term megascopic as herein used is defined as "perceptible through unaided vision or with the assistance of a pocket lens; used in contrast to microscopic with reference to objects or investigations in regard to which the use of a (non-single) microscope is not required (Century Dictionary, copyright 1914, page 3692). 1
What I claim is:
1. A relatively thin dipped sheet-like article of unmasticated rubber having an integral reinforcing bead at a sharp edge thereof, said bead being of greater thickness than that of the main portion of the article, and being generally semioval in outline.
2. A relatively thin rubber article having a margin with a megascopically jagged line edge. said margin being provided at such edge with a localized reinforcement thicker than the main portion of the article, said reinforcement having a cross-section, taken normal to the surface of the article, which is generally humped in outline.
3. A rubber article derived from a depositiontherein, the margin of the article at said opening being smooth and having an integral reinforced feather edge to form a constrictive gripping portion, said margin having a thickness greater than the main portion of the article and having a cross-section, taken normal to the surface of the article, which is substantially semi-pearshaped in outline.
6. A thin sheet-like rubber article provided with an opening therein, the margin of the article at said opening being smooth and having an integral reinforced megascopically jagged line edge to form a constrictive gripping portion, said margin having a thickness greater than that of the main portion of the article and having a cross-section, taken normal to the surface of the article, which is substantially semi-pear-shaped in outline.
7. An article comprising a body of relatively thin rubber havingone of its surfaces terminating in a line edge and provided with an integral ridge on its other surface, said ridge being localized adjacent said line edge and being thicker than the body of the article, said ridge tapering in opposite directions to said body and having one of its edges coincident with said line edge.
8. A stocking protector provided with a toe opening therein, the margin of the article at said opening being smooth and having an integral reinforced feather edge to form a constrictive gripping portion, said margin having a thickness greater than the main portion of the article and having a cross section taken normally to the surface of the article which is substantially semipear-shaped in outline.
