2 Claims. 1

This invention relates to life preservers and more particularly to an improved life preserver of the vest or jacket type. Life vests or jackets may be divided into two general classes according to the nature of their use. The first class consists of emergency jackets required of a navigation company to be readily available for emergencies as when a ship is in imminent danger of sinking. These preservers are generally quite heavy and cumbersome to the wearer. The second class of life vests consists of those which are owned personally and are expected to be worn continuously by persons while engaged in occupations or recreations which expose them to the danger of drowning. This invention lies in the latter class.

Life vests which are to be worn continuously must be comfortable to the wearer or their purpose will be defeated. If a vest is too heavy or cumbersome, the temptation to remove it will be great and its purpose will be defeated. This is particularly true because life preservers of this type are worn largely by persons engaged in recreation occuring during the summer months when the factors of comfort and coolness for the wearer are essential factors.

Many life preservers of the second class are well known to the art. However, the present invention constitutes certain improvements, not only embodying an improved feature for additional comfort but also an improvement regarding safety.

In many cases of accidents on the water the Victim is knocked unconscious at the time he falls into the water. When this occurs, it is necessary that the life preserver support his head in a position so that the face is not submerged. This has been accomplished in the past by providing a heavy collar of buoyant material attached to the life jacket around the neck which will cradle the head in a nonsubmerged position even when the muscles of the neck are limp. Although this jacket is useful in boat races, it is not satisfactory for jackets worn continuously. The present invention similates the advantages of such a jacket insofar as expected contingencies regarding unconsciousness are concerned, yet is more comfortable to wear.

One object of this invention is to provide an improved life saving vest which will be more comfortable to wear continuously and safer for the wearer than heretofore provided.

Another object is to provide a vest having an extra amount of soft buoyant material located about the wearers neck to cradle the head without having a collar attached to the vest, and

without the vest feeling stiff to the wearer out of the water.

Afurther object is to provide an improved light weight life vest having a high center buoyancy when worn, the center of buoyance being located so that the wearers body will lie in the water on a 45 angle insuring that the face will not be submerged. A further object is to provide a vest of universal size incorporating these features which may be worn with equal comfort by persons of various proportions.

Another object is to provide a life vest which is divided into an upper and lower section by a double row of spaced stitching which readily flexes for comfort and tends to prevent the saturation of the upper portion of the vest by capillary action of water within the buoyant material so that during the early minutes of use in water the extra buoyant effect of dry pockets over the shoulders holds the head high during the time the wearer would probably be unconscious.

Another object is to provide a vest which is reversible and may be Worn with either side out with the benefit of equal results either way.

These and other objects of the invention will be apparent to those skilled in the art from the drawings, the specification and the appended claims.

In the drawings:

Fig. l is a view of the preferred form of the invention as it appears when fastened in place on a person.

Fig. 2 is a back view of the vest shown in Fig. 1.

Fig. 3 is a view of the vest when unfolded and flattened.

Fig. 4 is a view of a person wearing this invention while floating in the water.

Fig. 5 is a section taken on line 5-5 of Fig. 3.

Fig. 6 is a section taken on line 6-6 of Fig. 3.

Fig. 7 is a section taken on line 'll of Fig. 3.

Fig. 8 is a section taken on line 8-8 of Fig. 3.

Referring now t Fig. 3 which shows the vest embodying this invention unfolded and flattened. The vest is formed of two layers 2! and 23 (Figs. 5 and 6), of preferably tightly woven cotton fabric, which are stitched or otherwise fastened together around the marginal edges to form an envelope. Various portions of this envelope are stuffed with a buoyant material, preferably kapok 9, either in pockets formed by stitches or quilted by additional stitching.

The minimum buoyancy of this life jacket relies completely upon the buoyancy of the filling material and not to the waterproof qualities of the fabric, for, in time, any fabric material will allow water to pass through it and a vest predicated on this method of achieving buoyancy alone would not support a victim for a long period of time. However, one of the features of the invention relates to a temporary employment of this additional buoyant effect in addition to the buoyancy of the material for certain advantages when extra buoyancy around the neck is desirable for a substantial length of time.

For the purpose of description the vest may be considered to consist of a back portion l2 and two symmetrical front portions l3 and M. The upper end of each front section l3 and I4 is stitched to the upper end of the back section 12 along the seams l and IE to define the arm holes IT and 13. The lower portion of each of the front sections I3 and It extends downwardly to form the skirts and 22. These skirts are separated from the major portions of the front sections 13 and M by an unquilted section 24 disposed between parallel lines of stitching, which unquilted section forms a shirr tube through which passes the draw string 25. The draw string 25 is anchored against removal by stitching or other suitable means as indicated at 25 substantially in the middle of the back portion l2. The function of this string is to secure the lower part of the vest around the waist of the wearer. The construction wherein the string is secured only at the point 26 makes it possible for the fabric to pucker in folds in the unquilted part of the back portion I2 insuring a snug fit even when the waistline of the wearer is considerably less than that of the vest. Two

ties

21 and 28 are provided on the upper portion of each of the front sections 13 and M for the purpose of securing the top of the vest about the chest of the wearer.

When the victim floats in the water the skirts 2i] and 22 are free to float upward and assume the position shown in Fig. 4. This serves to raise the center of buoyancy of the vest thereby producing greater stability.

The back section l2 of the vest has no skirt section attached and the lower portion of this section preferably is notstufied and quilted as is the remainder of the vest. However, the upper portion 30 bounded on the sides by the armholes is fully stuffed and quilted. This construction results in the wearers body being much more stable when in the water. All the buoyant material is concentrated above the bodys center of gravity. The upper portion 38 of the back section [2 is located above the bodys center of gravity when the body assumes the angle in the water shown in Fig. 4 so that buoyant material in this portion serves to provide greater rather than lesser stability.

A further advantage of having a mass of buoyant material 9 in the upper back portion 3!! is that this mass, in conjunction with the buoyant material in the upper portions 3i and 32 of the front sections l3 and I4, forms a cushion which serves to protect the head and neck of the wearer from suddent jerking should his body strike debris in the water. Should the wearer be unconscious, the cushion like mass will help hold the head in a position with the face above water, the weight and hang of the feet levering the body about this point for that purpose.

Furthermore, the relative locations of the buoyant material will roll the limp body of the wearer from face down to face up position if ever the wearer comes to the surface leaning forwardly. Not only this, but the buoyant portions ill in front at the chest and neck level are so arranged that the head will be tipped back and held upright.

For this purpose each of the two front sections 13 and I4 is divided into two portions separated by horizontal rows of spaced stitching 33 located level with the bottom of the armholes l1 and IS. The expanse of loose cloth defined by this double stitching 33 divides each front section 13 and it into an upper portion and a lower portion which flex readily with respect to one another for comfort, and for buckling upward slightly to move or hold the head in upright position tilted rearwardly. These portions are each tightly stuffed with buoyant material as pocketed or quilted by vertical stitching. The double row of spaced stitching additionally separates the quilted sections so that the upper portions will not become water saturated from the lower portion by capillary action through and within the closely packed buoyant material. With this arrangement the air space in the sections [4 in addition to the buoyancy of the material will be conserved during the time that unconsciousness is likely to persist even if the wearer is badly hurt, having in mind the reviving effect the water will have if the wearer hasnt been too seriously hurt to have a chance to survive.

The benefits of this feature are further revealed by the fact that, although it is merely a light weight vest, the vest will support the body of the victim in a stable position in rough Water to the best advantage for the operation of this feature. This is due primarily to the fact that the ultimate center of buoyancy is located above and in front of the center of gravity of the wearers body to assure a righting of the victims body and to maintain the body in an upright position at all times with a force greater than any tipping movement exerted by the waves. In fact any rocking motion caused by waves will cause the jacket to turn the wearers face away from an oncoming wave.

Consequently, it will be seen that between the free flexing of the vest at 33 out of the water. greater comfort is had while the free flexing of the vest at 33 in the water will cause this portion of the vest to rise and lift the head back with the face out of the water. Moreover, the break in the buoyant material at this point from the buoyant material lower down substantially delays or even inhibits capillary water displacement of air from around the closely packed kapok fibers in the upper portion [3 and 14.

On examination of the drawings and the foregoing remarks it will be apparent to those skilled in the art that a superior life preserver has been created which provides for the novel features and objects mentioned herein. This jacket, even though light weight and not bulky, will support the victims body in a stable position in smooth or rough water and if the victim is unconscious it will safely protect and support his head and neck to keep his face at all times exposed to the air.

It will also be apparent to those skilled in the art that various changes and modifications may be made in the life preserver of this invention without departing from the spirit of the invention whose scope is defined in the appended claims.
