LIFE-PRESERVER.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed August 23, 1919. Serial No. 319,407.

accompanying drawing, forming a part of this specification.

This invention relates to improvements in life preservers, and more particularly to a life preserver of theinfiatable type, which snugly fits the form of the individual wearin the same.

ife preservers are of use principally for two purposes, first for the saving of lives in cases of emergency, and second for floating the body of the individual wearing the preserver on the surface of the water, when the individual is learning to swim. The life preservers designed primarily for the emergency cases are ordinarily bulky and cumbersome in construction, and not very well adapted for swimming instruction, as they interfere with the free movement of the body and limbs of the wearer.

It is one of the objects of this invention to produce a life preserver which is formfitting, and substantially equally distributed over the torso, and which consequently does not interfere with the free movement of the limbs or body.

Another object consists in the construction of a form-fitting preserver which snugly fits over the chest, back and abdominal portions of the wearer, and which can be worn either over or under the bathing suit, whereby the necessary buoyancy will be obtained to maintain the body on the surface of the water, and which at' the same time does not disfigure the form of the individual wearing the preserver.

A further object of the invention consists in the production of a life preserver that can be attached to the inside of the bathing suit and properly inflated by the wearer after the suit and the associated preserver has been placed in position on the body of the wearer.

An additional object ofthe invention con sists in the production of a non-sinkable bathing suit in which the usual trunks and skirt or shirt appendage is attached to the lower edge of the life preserver whereby the entire garment has the general appearance of the usual two piece bathing suit consisting of shirt and trunks.

Other objects, features and advantages of the invention will become apparent from the following description, the accompanying illustration and the appended claims.

For the purpose of description several embodiments of this invention are illustrated in the accompanying drawings, in which:

Figure 1 is one form of the improved life preserver shown in front elevation and in position on the body of the wearer;

Fig. 2 is a vertical section through the life preserver shown in Fig. 1, shown in position on the body of the wearer and indicates the form-fitting characteristics thereof;

Fig. 3 is a front view of the life preserver, secured and fitted inside 'of an ordi-' nary type of bathing suit;

Fig. 4 is a vertical section of a combined bathing suit and life preserver illustrated in Fig. 3 shown in position on the bodyof the wearer;

Fig. 5 is another embodiment of the improved life preserver, equipped with an elastic means to increase the flexibility of the garment;

Fig. 6 is a further embodiment of the improved life preserver in front elevation, showing a corrugated type thereof, and

Fig. 7 is a vertical section of the corrugated preserver shown in Fig. 6 in position on the body.

As illustrated in Figs. 1 and 2, the life preserver 10 comprises an inner form-fitting wall or shirt 11, which is designed to closely *fit the torso, that is, it is constructed to adhere closely and follow the outline of the chest, back and abdominal portions of the wearer of the preserver. Secured to the inner wall or shirt 11, at the top and bottom edges 12 and 18 respectively, is the outer shirt or wall 14. The outer shirt or wall 14 is secured to the inner shirt or wall 11 at the respective edges 12 and 13 in any suitable manner, such as sewing or pasting, or in any way whereby an air and water tight union is obtained between the two Walls 11 and 14 at these edges. When the two shirts or walls 11 and 14 are thus combined, it will be. evident that an air-chamber 16 will be formed or established between the twovshirts or walls.

The outer wall 14 is fitted with an aperture at 17 over which is secured a flexible tube 18, the top end of which is fitted with a combination valve and nozzle 19, whereby the air-chamber 16*can be readily inflated by the wearer when the life preserver 10 is positioned on the body. The life preserver is preferably cutout under the arm pit as illustrated at 20, whereby free movement of the arm is obtained. To the upper ends of the bathing suit are secured the straps 21 and 22, which function as shoulder straps to properly position the life preserver in posicoated fabric, which is substantially water,

and air-proof, but obviously any suitable fabric without such coating may be employed with good results. The fabric likewise should be sufficiently pliable, and have a certain amount of yield, so that it can be conveniently drawn over the body of the wearer and snugl fit itself to the form of the individual. XVhen the life preserver is drawn on the body, the air-chamber 16 is preferably deflated and after the life preserver is properly positioned, the chamber 16 is filled with air by blow ing through the valve and mouthpiece 19. When the life preserver is fully inflated, the air is substantially equally distributed about the chest, back and abdominal. portions of the body, the air-chamber being preferably of a thickness of approximately from one inch to an inch and a half, such an air-chamber exerting a sufiicient buoyant effect to properly float the bod in the water in the swimming position. he tube 18 is preferably maintained in an upright position as illustrated in the drawings Figs. 1 and 2, by means of a strap 24, whereby the mouth-piece 19 will be convenient to the mouth of the wearer.

Figs. 3 and 4 illustrate the life preserver shown in Figs. 1 and 2 as it appears on the body of the wearer when worn under the bathing suit. Obviously the bathing suit can be independent of the life preserver and drawn over the preserver after it has been positioned on the body, or the life preserver can be permanently fastened to the bathing suit by stitching around the seams at the edges as illustrated at Figs. 3 and 4.

As illustrated in Figs. 3 and 4 a onepiece bathing suit consisting of the shirt 25 and the trunks 26 has the life preserver 10 permanently stitched. to the shirt 25 of the bathing suit by means of seams indicated by dotted lines at 27. Inasmuch as the total inflation of the life preserver 10 does not extend the outer wall of the life preserver more than an inch and a half at a maximum from the body of the wearer, it will be evident that the life preserver can be readily the wearer should get into water over his head, inasmuch as the buoyancy of the form-fitting life preserver will readily maintain the body on the surface of the water in the swimming position. Obviously the life preserver can be used with any of the well known styles of bathing suits of either the one or two piece type.

In order to eliminate the use of a separate bathing suit entirely and still maintain the appearance of the usual two piece bathing suit, the life preserver 10 can be used as the upper garment of the bathing suit,

by stitching, the lower or protruding end' 25 of the shirt 25 and the lower end 26 of the trunks 26. The appendages 25' and 26 secured to the lower end 13 of the life preserver 10 are attached to the garment to give it the usual appearance of a two piece bathing suit. Obviously these appendages can be secured to the life preserver 10 in any suitable manner. This construction in which the life preserver 10. is fitted at its lower edge with skirt or shirt and trunk ap pendages forms what may be termed a non.- sinkable bathing suit.

Fig. 5 illustrates a life preserver similar to that shown in Figs. 1 and 2, except that elastic bands 28 and 29 are inserted in each side of the life preserver so as to give the garment greater flexibility. The elastic bands 28 and 29 are separated in the middle 30 to interconnect the air chamber at the front with the air-chamber at the back.

. Obviously but one interconnection between connected in any desired manner, the perforations through the walls of the life preserver being properly sealed to make the garment water and air proof. In a corrugated life preserver of the construction shown in Figs. 6 and 7, the various corrugations are all interconnected so that the air will have free passage throughout the entire air-chamber, so that the preserver can be readily inflated by blowing into the valve and mouthpiece 19. Obviously any other method of corrugating the life preserver could be utilized.

It is to be understood that with all the forms of life preservers herein illustrated and described, bathing suits can be readily worn over the life preserver, and since the life preservers as well as the bathing suits are made form-fitting, no disfiguration of the form of the wearer results because of the wearing of the life preserver. Life preservers of this type, constructed in accordance with the teachings of this invention are made form-fitting the same as shirts, the form-fitting garments being made of various lengths, having the required chest, waist and hip measurements. These measurements will obviously vary in the life preservers that are to be worn by men and women.

From the foregoing description it necessarily follows that life preservers made according to the teachings of this invention, will snugly fit and cling to the body, and in their inflated position will assume the form of the body. Likewise that the air chamber utilized to give the desired buoyancy to float the body in the swimming position,

is evenly distributed over the chest, back and abdominal portions of the body, and since the maximum inflation is relatively slight, that no substantial disfigurations of the form will result. Consequently life preservers of this kind do not offer any hindrance to the movement of the body and limbs as required in swimming, and at the same time they constitute a garment which is pleasing to the eye, over which elaborate, dressy bathing suits may be worn, without figure or form distortion. Also when made in the form of a non-sinkable bathing suit, the general appearance of a bathing suit is obtained, and at the same time the necessary buoyancy required to float the body of the wearer is procured.

This invention is obviously not limited to the specific embodiments thereof herein illustrated and described, but is capable of many variations and other applications within the spirit of the invention as pointed out in the following claims,

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
