J. FROMM LIFE OR SWIMMING BELT.
Filed Nov. 1, 1935 Patented June 22, 1937 UNITEDTSTATES PATENT OFFICE In Germany November 2, 1934 g I 3 Claims. This invention relates to an improvement in swimming and life belts. More especially it re-' lates to an improved closure for use in connection with such belts, viz..for connecting the ends 'oi' the belt withone another.
g In normal state the belt constitutesa fiat'girdle encompassing the body of the bearer, the air-tight closure of the belt containing. a cartridge filled with a compressed gas which when permitted to escape into the hollow belt inflates it and the means for permitting the gas to escape. Such means are generally combined with thef'belt closure, but the known arrangements and combinations of this kind sufler from severe drawbacks in that they 5 renderithe use of the life or swimming belt diificult just incases of danger in which seconds may play a part. 5
The present improved belt closure is free from the above-mentioned drawbacks. The gist of the invention resides therein'that, firstly, the body of the closure consists of three parts, of which the one is air-tight inserted into one end of the belt, another is air-tight inserted into the other end 01 the belt, and the third constitutes a connecting member for said parts, and secondly, the arrangement is such that no member'protrudes to the outside and that springs or screwthreads or other unreliable members for effecting the discharge of the compressed gas from the I cartridge are completely obviated.
The invention is illustrated diagrammatically and by way of example on the accompanying drawing on which Figure 1 shows a perspective View of a complete swimming and life belt provided with a closure designed according to this invention. Figure 2 is a separate perspective view of the closure with some of the cartridge actuating means, drawn to a considerably larger scalerelatively to Figure l, and Figure 3 is an axial section through the closure, the cartridgeactuating means, and the belt ends, all parts in their proper or normal position with respect to one another, prior to use.
n the drawing I (Fig. 1) denotes the inflatable belt proper which consists of rubber or an-' other suitable material and has a thin wall, and 2 denotes the closure. It appears already from Fig. 1 that no part of the means for actuating the cartridge extends outwardly. The closure consists of three parts viz., firstly the tubular capsule. 3 which is inserted into the narrower end l8 (Figs. 1 and 3) of the belt, is air-tight connected therewith by vulcanization or cementing or in any other suitable way and is, furthermore, provided with a. few bores 24a; the second part is constitutedby a closure piece 4 inserted into the other end (22) of the belt and likewise air-tight connected therewith by suitable means, and the third, part is formed by a screw coupling 5 sleeve 1 bywhich the closure parts'3 and 4 can be securely, tightly, and detachably connected. with one another. Owing to the provision of an elastic packing ring 3 in said screw coupling sleeve, or between the annular faces ofthe rim '8 of the capsule 3 and of the closure piece 4 respectively, the connection isair-tight, as well as water-tight. The shape of the parts 3 and 4 is such that the entire closure is accommodated to the curve of the waist of the bearer. i In the closure part} 4 is a recess I4 (Fig. 3) in which is supported on apin IS a bell-crank lever IG- having a shorter arm I! and a longer arm 23. Said arm "forms at its end a nose which is located opposite the head l8 of a grooved piercing vpin l2 loosely guided in a bore i3. The longer lever arm 23 extends into the belt (Fig. 3) and is subject to the action of a plate-spring l9, one end of which is afllxed at to the bell-crank lever and the other end of which bears upon an extension 2i of the closure piece 4 (Figs. 2 and 3). The parts Ii, 23 and I9 extend in the axial direction of the hose, as shown in said figures.
Counter to these members, the closure piece 4 projects out of the hose and is there provided with a screw-thread onto which is screwed the cap-nut I. The free end of this sleeve engages a flange 8 provided at the likewise projecting end of the tubular capsule 3 which, as has already been mentioned, constitutes a member of the three-parted closure. In said capsule 3 is located the cartridge 5 which contains the compressed gas and the discharge end of which is located just opposite the pointed end of the grooved pin H which is able to pierce the stopper 40 I of the cartridge when it is driven forward by means of the bell-crank lever. When all members are in the position shown in Fig 3,.which position they assume when the closure parts are firmly connected with one another and the pack ing ring 9 is, therefore, compressed, the entire closure is in operative condition.
It is not necessary to close the belt already prior to use. 4 It may be closed partly after it has been laid around the waist when it will form a sort of a flat girdle which does not in the least 1 prevent the bearer from performing in the water all sorts of movements he may desire, including, as a matter of course, swimming. If any circumstance occurs which necessitates the bearer to inflate the belt so as to convert it into a. life-belt proper, nothing else is requisite but to compress the belt at the place where there is the leverarm 23 whereby the grooved piercing pin II will be driven through the stopper into the discharge end of the cartridge 5, whereupon the gas will escape through the channels 24 into the belt and inflate it.
It is, of course, also possible to inflate the belt already prior to use, for instance on shore, and to throw it in this state towards a man who is in danger to drown.
After use the belt can be easily drawn off from the body and kept anywhere in inflated state. Or,if it is throught proper to provide it with a fresh filling, or with a fresh cartridge respectively the cap nut I is loosened whereafter the gas present in the belt can freely escape and another cartridge can be inserted into the tubular capsule 3. When then the sleeve 1 is again screwed home, the belt is again ready for use.
I claim:

short arm being located opposite said pin and the long arm extending longitudinally into the belt counter to the said pin; a spring so arranged as to be adapted to hold the lever in its position of rest; a threaded coupling sleeve engaging the flange of a the said capsule and the screw-threaded'part of the said closure piece for connecting the two belt-ends with one another; and a packing ring inserted between the oppositely located faces of the rim of the capsule and of the closure piece.
