Application filed September 18, 1920. Serial No. 411,286.

To aZZ whom it may concern:

Be it known that I, VICTOR GUINZBURG, a. citizen of the 'United States, and a resident of the city, county, and State of New York, have invented a certain new and useful Improvement in Flotation Devices, of which the following is a specification.

This invention relates to a flotation or swimming device in the nature of an inflatable bagv havin 'means for securing it to the body and a apted to be used to support the body while in the water.

The object of this invention is to provide a device, which will be simple and economical in construction, which will be-eifective in operation and which can be worn without interfering with the movements of the body while swimming.

With these objects and other objects in View, I have devised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawing forming a part hereof in which Figure 1 is a plan View of a flotation device made in accordance with my invention.

Fig. 2 is a transverse sectional view of the same on the line 2-2 of Fi 1.

Fig. 3 is a sectional view on t e line 3-3 of Fig. l, looking in the direction of the arrows.

Fig. 4 is a sectional view vof a portion of the inflatable bag showing the construction of the inflation valve.

Fig. 5 is a sectional View on the line 6-6 of Fig. 1 looking in the direction of the arrows.

Fig. 6 is a view showing the manner in which the device appears when in use.

Throughout the various views of the drawings, similar reference characters designate similar parts. In the preferred einl bodiment of my invention as disclosed in the accompanying drawing, l indicates an inflatable bag which is substantially rectangular in shape rand may be made by transversely folding a square section of material and securing the edges together. The edges of the bag l are secured together by stitching 2 and are additionally reinforced by means of a binding strip 3 which incloses the edges and is cemented thereover. The manner in which the device is manufactured forms the subject matter of a separate application for l strip of material folded upon patent, said a plication being' Serial No. 411,285, med epi. 18, 1920.

At 4 is the inflation valve which consists of a collapsible or flexible 'rubber tube 5 which lies between the folds of the bag and extends substantially co-eXtensive with the outer or free edge 6 of the bag. This tube 5 1s cemented or otherwise secured to the bag 1 and secured within the tube 5 is a threaded'sleeve 6a. The sleeve 6 proj ectsoutside of the bag and is adapted to receive a closure cap 7 to prevent the escape of air from the interior of the bag.

It will be seen that the bag may be inflated by means of air blown through the sleeve 6a and through the flexible or collapsible tube 5. To prevent the escape of air 'while the cap 7 is being placed in position, the flexible or collapsible tube 5 may be squeezed or pressed together as indicated by the dotted lines in Fig. 4.

At 8 are the tapes which are utilized .to secure the device about the body of the user. These tapes are attached to the bag 1 through the medium of triangular tabs 9. These tabs each consist of itself with the tapes 8 lying between the folded portions and cemented therein.

If desired however, the tabs 9 may comprise two sections of material adhesively secured together with the ends of the tapes vnecessity for 'stitching them in place or otherwise perforating the inflatable bag.

In addition, the arrangement of the tabs forms a substantial joint at the corners of the bag and 'aids in preventing leakage of air at those points.

In Fig. 6, the manner in which the device is used is disclosed. The bag is secured about the body by means of the tapes 8 and the bag 1 is freely pivotal in any direction that it may be moved by the pressure of the water. The position in which the device is used enables it to be worn without in any Way interfering with the movements of the wearer. The device is preferably made of a rubberized, air and waterproof' material, enabling it to be inflated and retain the air indefinitely. Usually, devices of this character are made of a material which will not retain the air until they are moistened by the water and they cannot be inated while they are dry. In applicants construction, however, a material is preferably used which will enable the device to be inflated regardless of' whether it is moistened or not. Such a material may be thin rubber sheeting, rubberized silk or any material of like character.

From the foregoing, it is obvious that my invention is not to be restricted to the exact embodiment shown but is broad enough to cover all structures coming within the scope of the annexed claims.

What I claim is 1. A device of the class described coniprising an inflatable body, tabs extending from the securing edge of said body and securing tapes held within said tabs.

2. A device of the class described comprising an inflatable body, tabs pendant therefrom, securing tapes held within the tabs and overlying the inflatable body.

. 3. A device of the class described comprising an inflatable body having a securing tape, a tab secured to and projecting from said body, said tab comprising a triangulated strip of material folded upon itself with a portion of. the inflatable bag lying between and secured to the folded portions of said tab, said tape having one of its ends seured between the folded portions of said ta 5. A device of the class described comw prising an inflatable bag, securing tapes projecting from two corners thereof and an inflation valve lying co-extensive with the outer edge of said bag with its end projecting outside of said bag.

6. A device of the class described comprising an inflatable bag having a securing tape, a tab in which said tape is held, said tab comprising two layers of material be tween which a portion of the inflatable bag and one end of the tape is secured.

Signed at the city, county and State of New York this 16th day of September, 1920.

'VICTOR GUINZBURG.
