Application June 10,

- 2 (Jlaims.

My invention relates to a moisture proof dual type closure slide fastener device for joining abutting edges of waterproof sheet material usable in the construction of apparel, tents, and what not. 1

Heretofore the so-called zipper devices have been used on shoes, shirts, and various articles of manufacture. Such devices have not, however, been used as a means of rendering the joints in overshoes, raincoats, and the like waterproof, and it is for such purpose the present invention is designed.

The principal object of the invention is to provide a waterproof closure embodying the well known zipper type of fastener, which device can be applied to various articles, such as shirts, fishing garments, raincoats, overshoes, tents, and the like.

Another object of the invention is to provide a device of this character in which dual-type zipper closure means is employed in order to effectively render waterproof and moisture proof the various articles to which the device is applied.

Other objects and advantages will be apparent during the course of the following description.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings, in which:

.Figure 1 is a front view of a jacket showing the device attached and in open position.

Figure 2 is a horizontal sectional view taken on the line 2--2 of Figure 1.

Figure 3 is a fragmentary front view of a jacket disclosing the compressible endless bead before the outer zipper fastener is applied.

Figure 4 is a front view of arubber suit or fishing jacket showing the device attached and in closed position.

Figure 5 is an end elevation of a waterproof tent showing the moisture proof closure fastener, embodied therein.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 6 designates a compressible endless bead which is best illustrated in Figures 1 and 3. The bead 6 is suitably connected with companion sheet portions 1 of the waterproof fabric. It is to be understood, of course, that the compressible endless bead 6 having the companion sheet portions 1 of waterproof fabric is adaptable for use in fishing jackets, tents, and the like.

1931, Serial No. 141,555

In the preferred form of construction I pro- I vide a dual-type closure fastener embodying an inner slide fastener, as indicated as a unit by the letter B, and a corresponding outer zipper slide fastener indicated as a unit at A. The inner zipper" fastener includes track devices 8 and 9 which interlock with each other and are adapted to compress the inner edges of .the bead 6 tightly together to prevent the entrance of water, moisture, or other like substance. The numeral I designates a slide fastener having a metal pull cord indicated at H for moving the slide and drawing the devices 8 and 9 into interlocking engagement with each other.

The outer zipper fastener A also comprises flexible track devices designated at I2 and I3 adaptedto' interlock with each other which are provided with a slide fastener 14 having a metal pull cord I for the purpose of moving the track members l2 and I3 into interlocking engagement.

From the foregoing it will be seen that I have provided a waterproof and a moisture proof closure which can be used on various articles of apparel, as well as tents and other articles of manufacture, and one which will be impervious to foreign matter due to the dual-type sealing means embodied in the present invention.

The gist of the invention resides, it is believed, in providing opposed edges of sheet material with integral ribs or heads, the latter features being compressible and drawn into water-tight contact under the action of the alternately operable inner and outer slide fasteners.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Since excellent results are obtainable from the details disclosed, they are preferably followed. However, within the scope of the claimed invention, numerous modifications may of course be made.

- I claim:

1. In a structure .of the class described including companion portions of waterproof sheet material, the abutting edges thereof being in the form of opposed complemental waterproof beads, an outer slide fastener secured to the corresponding outer surfaces of said sheet material for cooperation with the beads, and a separate and independent inner slide fastener secured to the inner surfaces of said companion portions for cooperation with said beads, and said slide fasteners being individually and successively operable and closable;

2. In a garment, a jacket having a neck opening, said neck opening being completely bounded by a marginal compressible bead. portions of said bead being in opposed abutting parallelism, an outer zipper-type slide closure secured to the correslx lding outer surfaces of said sheet material ior coperation with the beads, and a separate and independent inner slide i'astener secured to the inner surface of said companion portions for cooperation with said beads, and said slide fastener being individually and successively oper- 5 I able and closable.

SAMUEL CHESTER FERRONE.
