Johnnie 6. Jordan United States Patent 3,621,501 LIFE PRESERVER WITH FLASHING DISTRESS SIGNAL Johnnie B. Jordan, Silsbee, Tex., assignor of fractional part interest to Carl R. Griflith, Beaumont, Tex. Filed Oct. 21, 1969, Ser. No. 868,037 Int. Cl. B63c 9/20 U.S. Cl. 9--313 4 Claims ABSTRACT OF THE DISCLOSURE A U-shaped neck embracing shoulder-supported collartype. life preserver has the forward ends of its legs equipped with a pair of depending ballast-like adapters. A median top surface portion of one leg of the life preserver has a built-in flashlight with an exposed amber colored distress signalling lens. The flashlight bulb is automatically flashed on by a float operated switch when the overboard wearer is imperiled in the water.

This invention relates to certain new and useful improvements in a life preserver, more particularly, one wherein a U-shaped or an equivalent buoyant collar is equipped with a self-contained easy-to-spot distress signalling light which comes into play when the wearer enters the water, and wherein a float operated switch turns the light on automatically.

Persons conversant with the field of invention under consideration are aware that float-operated switch devices which are responsive to immersion in a body of liquid and wherein a float ascends to close an electric circuit are, generally stated, old and well known.

An object of the present invention, broadly stated, is to improve upon prior art signalling life preservers by providing a simplified and acceptably practical life preserver having novel flashlight means and accompanying switch means which is expressly designed and adapted to enable members of a rescue group to spot and facilitate an overboard person, particularly at night.

Briefly the concept pertains to a suitably buoyant life preserver, more precisely, a substantially U-shaped life preserving collar which embodies a pair of legs united at their rearward ends by a bight portion, said bight portion being adapted to bridge the nape and back of the wearers neck and said legs being adapted to embrace and encompass diametrically opposite sides of the neck and, in so doing, to reside for retentive support atop the wearers shoulders. In carrying out a preferred embodiment of the invention the forward end portions of the legs of the collar are provided with individual elongated depending ballast-like members. These members are vertically elongated and are such in construction and performance that they position and, being side by side, are capable of hanging down in a vertical position over the wearers chest. They provide balancing adapters for the over-all life preserver. A distress signalling flashlight is built into one of the legs and has an easy-to-see flashing lens which protrudes beyond a viewable top surface of the leg with which it is associated. A float operated switch means for the flashlight is operatively associated with one of the adapters and is automatically operated when the distressed imperiled wearer is overboard in the water.

To the ends desired the fiashlight comprises a case containing coordinated companion flashlight batteries, and an enclosed cup-like well which provides a light beam reflector and also a partial enclosure for the cooperably enclosed lamp bulb. The lens is lined up with the open side of the cup-like well or reflector and is so located that it protrudes beyond the surface of the coacting leg where it can be readily seen for reliable rescuing needs.

In carrying out a preferred embodiment of the invention the switch means comprises a cylinder which is closed at an upper end and is open at its lower end. A stationary contact is fixed in the closed end portion. A spring contact finger is provided and has an end anchored in the closed end of the cylinder and a free flexible end portion is arranged so that it can be sprung toward and from the fixed contact. This end portion is normally disengaged from the stationary contact. A water pressure responsive float is freely reciprocable within the confines of the cylinder, that is the chamber thereof, and is adapted when operating to press and hold the free end of the finger in a circuit closing position against the stationary contact.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a view in perspective of a life preserver with a flashing distress signal and float operated switch constructed in accordance with the invention and shown in readiness for use.

FIG. 2 is an enlarged view of the battery operated specially constructed built-in type flashlight, parts being shown in elevation and section.

And FIG. 3 is also a suitably enlarged view which shows the flashlight in section and elevation and observing one lengthwise edge thereof and which also shows the float operated switch means, with the float disengaged and the switch open.

Referring now to the Views of the drawing and particularly with reference to FIG. 1 the life preserver is characterized by the aforementioned U-shaped (also horseshoe shaped) life preserver which is here designated, specifically stated, as a collar 6. This collar is of appropriate buoyant construction, that is, comprises an outside jacket or casing with interior buoyant filler media (not detailed). The opposed coplanar legs of the collar are noted at 8 and the rearward ends are joined by a rounded bight portion 10. The bight portion is adapted to bridge the nape and back of the neck of the wearer and the arms or legs 8 are adapted to embrace diametrically opposite sides of the neck and to rest for support on the shoulders of the wearer as brought out in phantom lines in FIG. 1. The forward end portions 12 are provided with the vertically elongated bag-like members which are of appropriate relatively heavier but buoyant material. These members are designated, more specifically stated, as ballast-like adapters whose upper ends 14 are connected with the forward ends 12 of the legs of the collar as shown in FIG. 1. The respective adapters which are alike in construction are denoted, generally stated, by the numeral 16.

These adapters are suspended when in use over the chest of the wearer or adjacent thereto in the manner sug gested in FIG. 1.

The distress signalling means is embodied in the median top portion of one of the two legs as also shown in FIG. 1. This means, generally stated, is denoted by the numeral 18 and comprises a battery containing flashlight. The elongated box-like case is denoted at 19 and is provided at the lower portion (FIG. 2) with spaced coordinating dry cell batteries 20. These batteries are arranged and confined to receive current from an appropriate conductor denoted generally at 22. The batteries are electrically coordinated with a screw-threaded neck 24 (FIGS. 2 and 3) provided on one peripheral wall of a cup-like well 26 which is suitably mounted and provides a receiver and reflector for the enclosed lamp bulb 28 whose neck 30 is screwed into the socket-like neck 24. This well receiver is lined up with an opening provided therefor in the top wall 32 which is constructed to accommodate and supportively locate concavoconvex suitably protruding laterally disposed amber colored lens 34. These components withinthe case are electrically united in the manner detailed in FIG. 2.

The aforementioned float operated switch means is operatively connected with the flashlight in the manner detailed in FIG. 3. Specifically, this means comprises a cylinder 36 the hollow or internal portion of which provides an appropriate cylindrical chamber 38. The lower open end 40 is provided on the interior with a suitably attached rivet or the like 42 which constitutes a limit stop for the reciprocable float 44. The float is shown in a position in readiness to trip the switch means in FIG. 3. To the ends desired the upper closed end of the cylinder is denoted at 46 and comprises a plug or the like which is screwthreaded and screwed into the internal screw threads 48 at the upper end of the cylinder. One current conducting wire 50 is connected with an internal head or the like which provides a relatively stationary contact element 52. The other wire 54 is connected to a similar rivet 56 which carries a resilient circuit make-and-break finger 58.

It will be noted in FIG. 1 that the flashlight is incorporated in the right hand leg of the collar 6 in such a manner that the lens 34 protrudes and assumes an easy-to-see position. On the other hand the aforementioned cylinder is embedded in the right hand ballast-like adapter 16 as also shown in FIG. 1. This is to say the major portion of the cylinder as embedded in the wiring is also suitably embedded. The lower open end of the cylinder protrudes below the coacting lower end portion 60 of the adapter in a manner to permit the column of water (not shown) to enter.

In actual practice the collar is Worn around the neck and above the shoulders in the manner illustrated in FIG. 1. When in this position the depending ballast-like adapters assume a side-by-side position. If follows that when the wearer enters the water, a column of water ascends into the float chamber and acts on the float 44. The float is thus forced up and engages the switch finger 58. The switch finger is forced against the stationary contact 52 and when the circuit is thus closed the bulb or light 28 comes into play and functions in the manner illustrated in FIG. 1.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
