J. ROBERTSON LIFE PRESERVER Filed Oct. 20. 1931 INVENTOR, /a/mu fi 5W ATTORNEY Patented Dec. 12, 1933 UNITED STATES PATENT OFFICE 8 Claims.
This invention relates to improvements in life preservers.
An object of my invention is to provide an improved life preserver which is adapted to support the wearer in a position with his head well above the surface of the water.
Another object of my invention is to provide an improved life preserver having the buoyant material therein so disposed as to automatically cause the wearers body to assume a rearwardly inclined position in which the head is supported well above the surface of the water.
A further object of my invention is to provide an improved life preserver having a chin rest which prevents the wearers, head from dropping forwardly even though consciousness might be lost from exposure or through other causes.
A still further object of my invention is to provide an improved life preserver adapted to fit persons of different sizes, having the buoyant material therein so arranged as to automatically cause a person wearing the same to assume a position with his face disposed in an upward direction and well above the surface of the water.
Other objects more or less apparent will pre' sent themselves or will be specifically pointed out in the description to follow.
In the accompanying drawing:
Fig. 1 is a plan view of a life preserver constructed in accordance with my invention;
Fig. 2 is a side view showing my invention secured upon a wearer;
Fig. 3 is a sectional view taken on the line 33 of Fig. 1; and
Fig. 4 shows a portion of one of the spring contained securing straps, the outer covering thereof being partly broken away and in section.
In constructing my improved life preserver I preferably out two layers of canvas or other suit- .19 able fabric into the desired shape and size and place suitable quantities of kapok or other buoy- ,ant material between the layers before sewing their edges together. The device is comprised of three main buoyant compartments 1, 2 and 3, the compartment 1 being disposed at the lower end, the middle compartment 2 being connected to compartment 1 by a flexible strip 4, and the compartment 3 being disposed at the opposite or upper end. An inverted U-shaped opening 5 5 i" formed between the compartments 2 and 3, the id opening having a rounded top end 5 which extends into the compartment 3. The compartments 2 and 3 are joined together by narrowed kapok filled shoulder portions -6, which, by reason of their comparative narrowness, are somewhat flexible. Extending upwardly fromthe upper end of the compartment 2 and disposed between the shoulder portions 6 is a protruding member or chin rest '7 which is adapted to extend under the chin of a wearer and thereby prevent his head from dropping downwardly. In order to automatically position the body of the wearer with his face upward and lifted well out of the water, I have distributed the buoyant material in the various compartments in such a manner that compartments 2 and 3 are sufficiently buoyant to effect the desired results. The compartment 2 is normally located on the breast of the wearer with the upwardly protruding member 7 positioned under the chin. The compartment 2 serves to automatically position thebody of the wearer so the face is turned upward. The compartment 3 is so disposed with'reference to the middle compartment that it lies beneath the back of the wearers head and forms a rest and support therefor. The compartment 3 may be provided with a crease 8 within which. the wearers head normally rests, while the compartment 2 may be provided with a similar crease 8 which permits the side edges of the said compartment to be drawn closer to the breast.
The means employed for securing the device upon a wearer consists of two straps 9 fastened at ends thereof to opposite side edges of compartment 3. The straps extend downwardly through rings 10 secured to opposite sidehedges of the compartment 2, at points beneath the shoulder portions 6. The straps are each preferably provided therein with one or more coiled springs or other suitable resilient means 11 which enable the device to be secured upon bodies of diiferent sizes. Suitable fasteningmeans 12 provided on the free ends of the straps permit the securing of the said ends together.
A person desiring to use the device first places his head through the inverted U-shaped opening 6, thereby causing the compartment 2'to become positioned on his breast and the compartment 3 back of his head. The straps 9 are crossed at the back of the wearers body and then brought forward over the flexible strip 4 to a point in the front where they are fastened together. In fastening the straps together a downward pressure is exerted upon the sides of compartment 3, thereby causing the rounded lower edge. thereof to firmly contact with the lower part of the wearers neck. The tension of the springs 11 in the straps not only causes the compartment 3 to be maintained in a secure position against the lower part of the head of the wearer, but also maintains the compartment 2 firmly against the wearers breast. When the device has been placed in operative position upon a person it is almost'impossible to effect its detachment except by. unfastening the ends of the straps. The proper functioning of the compartments 2 and 3 in automatically causing a. persons body to assume a rearwardly inclined position in the water, is materially assisted by the lower compartment 1 which turns upwardly upon the strip 4, thereby contributing consider-- ably in turning the person upon his back or into the required position. It is to be observed that the buoyant compartment 2, the buoyant compartment 3, the buoyant shoulder portions 6 and the chin rest 7 are formed integrally with one another, and that they cooperate with one another to support a wearers body in such a position that his head is maintained above the surface of the water with his face upwardly disposed. The buoyant shoulder portions 6 and the upper compartment 3, which forms the head rest, cooperate with one another to normally maintain the chin rest 7 in such a position that the wearers head cannot drop forwardly.
Although I have shown and described a life preserver construction constituting the preferred embodiment of my invention, still, it is recognized that the principles thereof may also be embodied in other forms or shapes having considerable merit. For this and other apparent reasons, I desire my invention included broadly within the spirit of the appended claims rather than limited to the exact construction herein shown and described.
