'disengaged and the two elements separated in a patent of the United States, granted on Decemquick, easy and expedient way, therefore, auch ber'31st. 1918-, No. 1,289,476. An opening is proseparable f means'are highly desirable in many places where two elements are to be secured or opened in a speedy and eicient manner, like-in said opening in my mentioned life preserver suit, and in many other instances.

One disadvantage of applyig such quick separable fastening means between twoelements lies in the fact that such elements will not provide a water, liquid, or, much less, vapor or gasproof connection between the two elements, and it is the main purpose of my invention, as has been pointed out hereinbefore, to provide i means in connection with such separable fasteners whereby the same may close on one another with substantially tight sealing effect.

For this purposegin the embodiment selected as illustrative in this application, I vsecure left hand and right hand elastic strips of material 25 and 26, respectively, underneath and to the fastener strips 15 and 16, said elastic strips preferably being made of appropriate rubber material, and in the embodiment shown, the right hand one being provided with a longitudinal projection 27, while the left hand one will be provided with a corresponding and registering depression 28. When the mentioned fastener means connect the elements 13 and 14 they also will cause the two rubber strips 25 and 26 to tightly engage vone another along their separation line 29 and to make this sealing effect more secure, the projection 27 and depression 28 have been provided, the projection entering said depression and being tightly pressed thereinto (Fig. 3), while when the separable fasteners are opened, as indicated in a portion of Fig. 2, the rubber strips 25 and 26 will also be disengaged, as indicated in Fig. 5. The lower end 12 of the opening or slit 24 in the material 10 is permanently and tightly closed by any appropriate means V12a well known in the art, while I employ a piece or sheet of rubber material 30 to tightly seal the upper end of said opening or slit in the material "10, when it is so desired, namely, when the two edges 13 and 14 are tightly closed together.

Said rubber piece 30 is secured underneath the upper ends 31 and 32-of the fastener strips 15 and 16, which, at the upper portion thereof, are devoid of the separable fasteners 18 and 19 and are also secured to the intact adjacent portion 33 of the material 10, or in case two separate pieces of material are to be secured together then to the similarly located portions'of eaeh`of them. The lower end of the rubber piece 30 shows two inclined sides 34 and 35, at the right and left sides thereof, and the sealing rubber strips 25 and 26 have similarly inclined terminations or upper edges 36 and 37 in co-operatively adjacent relation to said sides 34 and 35. The edges 34 and 35 carry wedge shaped projections 34a and 35a which may engage similarly shaped depressions in the edges 36 and 37 of the strips 25 and 26 so that said sides of the rubber piece 30 and said ends of the rubber strips 25 and 26 may engage one another in a tightly sealing manner when the separable fastener means are completely closed and their securing action reachessaid ends 36` and 37 of the rubber strips 25 and 26. The rubber piece 30 is tightly secured to the undersides of the fastener strips 15 and 16 and to the respective portion 33 of the material 10 thereabove, but only on about a surface indicated by the dotted cross-hatching lines 38 so that when the ends 36 and 37 of the rubber strips are closed upon the sides 34 and 35 of the rubber piece or block 30 a complete sealing eiect will be provided for the vupper end of the slit 24. For a smoother working of the closing of the rubber strips 25 and 26 on the rubber block or piece 30 or for their easier disengagementtherefrom some superfluous or added materials 40 and 41 may be provided in fastener strips 15 and 16, respectively, which, in the opened position of the two element are illustrated in Fig. 2, as stretched downwardly and outwardly underneath the material 10 which also may be'somewhat increased at these places. In the closed position of the parts,

as illustrated in Figs. 1 and 4, said increased or superfluous materials will show` in wrinkles 42 and 43. In a similar manner, the upper free portions of the edges 13 and 14 may adjust themselves in some wrinkles 45 vand 46 when in an opened position (Fig. 2).

It will be understood that changes and variations may be made in the parts and combinations of my device and I hereby reserve all my rights to any and all such changes as are within the spirit of the invention and the scope of the appended claims.

What I claim as new, is:

l. In combination with means adapted to secure together two adjacent elements or to permit them to separate, an elastic strip of material secured to each of said elements adjacent to the fastening means thereon, the two elastic strips on said two elements tightly engaging one another when the elements are secured together and so to provide a substantially air, gas liquid and moistureproof sealing along the separation line of said two ele-- ments, a cross piece of elasticmaterial at the termination of the separation line of said two elements being tightly secured toboth of said velements and engaging each of said elastic strips of material for tightly sealing the termination .of said separation line, said cross piece having inclined sides adjacent to said strips of material' and said strips having correspondingly inclined ends to engage said inclined sides.

2. In combination with means adapted to secure together two adjacent elements or to permit them to separate, an elastic strip of material secured to each of said elements adjacent to the fastening means thereon, the two elastic strips on said two elements tightly engaging one another when the elements are secured together and so to provide a substantially air, gas liquid and moistureproof sealing along the separation line of said two elements, a cross piece of elastic material at the termination of the separation line of said two elements being tightly secured to both of said' elements and engaging each of said elastic strips of material for tightly sealing the termination of said separation line, said cross piece having inclined sides adjacent to said strips of material and said stripshaving correspondingly inclined ends to engage said inclined sides, said inclined v sides and ends also having respective depressions and projections drawn into tight engagement with one another when said two elements are closed and fastened together.
