     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 13 thereof, a new and improved rescue buoy apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the rescue buoy apparatus 10 of the instant invention essentially comprises a lower housing 11 securable in an upper housing 12, with the lower housing 11 including a lower housing weighted floor section 13 utilizing a component such as lead, mercury, and the like to stabilize the housing in use in a water or ocean environment, as illustrated in FIG. 12. The lower housing 11 includes a lower housing cavity 14 arranged to rotatably mount a spool 16 therewithin. An upper edge of the lower housing includes an upper edge resilient seal 15, wherein a lower edge resilient seal 21 is mounted to the lower edge of the upper housing 12. An intermediate floor plate 20 is mounted between the upper edge seal 15 and the lower edge seal 21 utilizing latch members 19 mounted about the periphery of the upper and lower edges of the lower and upper housings respectively to secure the housings together. 
     An elongate flexible tether line 17 is wound about the spool 16 and is directed through a tether line floor plate feed bore 31 through the floor plate and then through a tether line upper housing guide bore 30, as illustrated in FIG. 13 for example. A plurality of guide loops 62 are positioned in alignment underlying the tether line upper housing guide bore 30, with the tether line secured to a boat &#34;B&#34;, as illustrated in FIG. 12. It is contemplated that the organization be mounted within a framework permitting release of the apparatus 10 upon an emergency situation such as a sinking of the boat, as illustrated in FIG. 12. 
     It should be noted, as illustrated in FIGS. 13 and 11, that a spool brake 28 is mounted within the lower housing cavity 14 and aligned, wherein a spool brake groove 50 rotatably receives a spool flange 18 of the spool 16. A piston 51 positioned within the groove 50 is operative through a solenoid and relay 52 to effect projection of the piston 51 to effect frictional engagement with the spool flange 18 upon actuation of a switch member 29, in a manner to be discussed below, to provide a constant frictional engagement permitting a metered rotation of the spool 16 providing a controlled release of the tether line 17 from the spool 16 preventing its breakage during release. 
     A radio transmitter 22 is mounted to the intermediate floor plate 20 and operative through a radio antenna 23 to effect transmission of a radio signal upon actuation of the switch assembly 29. 
     An A-C/D-C convertor 24 is provided to provide for recharging of a battery 34 (see FIG. 5 for example) during maintenance of the apparatus 10 prior to its positioning within the boat &#34;B&#34;. The convertor 24 is operative in a conventional manner to effect charging of the battery 34. An illumination light member 25, as well as the radio transmitter 22, are mounted to the upper housing roof plate 27 in a generally orthogonal relationship, wherein the light member 25 includes a flasher unit 25a mounted fixedly to a shaft support in the illumination light member 25 to effect its selective illumination in a flashing manner. The switch assembly 29 includes a housing to include a roof 29a, with a rear wall 33 and a floor. The switch assembly includes a switch assembly cavity 35 receiving the battery 34 and a wiring harness assembly 36 cooperative with the plurality of switches defined within the switch assembly 29, wherein the switch assemblies include a first switch rod 37 cooperative with a first switch, a second switch rod 38 cooperative with a second switch, a third switch rod 39 cooperative with a third switch, and a fourth switch rod 40 cooperative with a fourth switch. Wiring from the wiring harness assembly 36 is directed through a wiring harness bore 32 with an intermediate floor plate 20 cooperative with the spool brake 28 and subsequently to the radio antenna 23, the illumination light member 25, and an inflation assembly to include an inflation balloon housing 26 that is mounted orthogonally within the upper roof plate 27. The switches each include a loop defined by a respective first, second, third, and fourth loop 37a, 38a, 39a, and 40a, each mounted to an exterior end portion of each respective first through fourth rod, as illustrated in FIG. 3 for example. The flexible tether line 17 is directed through each rod from the spool 16 and subsequently through the tether line upper housing guide bore 30 to the boat &#34;B&#34;. The switch assembly 29 is diametrically mounted within the housing and on the intermediate floor plate 20 in an opposed relationship relative to the tether line upper housing guide bore 30, whereupon as the tether line 17 is directed exteriorly of the housing and as the housing is elevated upwardly relative to the boat &#34;B&#34;, the first through fourth switch rods 37-40 are extracted exteriorly of the switch assembly housing to effect closure of each normally opened switch therewithin. FIG. 4 illustrates operation of each switch that includes a first electrical contact member fixedly mounted to the switch assembly roof 29a, with a second electrical contact member 42 reciprocatably mounted relative to a switch assembly intermediate web 43. The first and second contacts are in alignment relative to one another in a spaced relationship and maintained in that relationship by reception of a switch rod abutment plate lock rod 47 mounted within a switch rod abutment plate 46 that is orthogonally secured to an interior end portion of each respective switch rod. The lock rod 47 is slidably received within a lock rod receiving bore 48 within a second switch member rod support 49. Upon reciprocation exteriorly of the housing of each switch by the respective rod, such as a rod 37, the lock rod 47 is removed from the receiving bore 48 to permit the second contact member spring 45 captured between the switch assembly and intermediate web 43 and the second electrical contact member 42 to project a second electrical contact member 42 upwardly into electrical communication with the first contact member 41 effecting electrical communication of that switch and completion of that circuit to thereby power an associated organization, such as the transmitter 22 in use. The first switch rod 37 is operative to effect actuation of the inflation balloon assembly mounted within the inflation balloon housing 26. The second switch rod 38 is operative to effect actuation of the radio transmitter, the third switch rod 39 is operative to effect actuation of the light member 25, and the fourth switch rod 40 is operative upon extraction from the switch assembly housing to effect actuation of the spool brake 28. 
     The inflation balloon housing 26 includes a balloon housing lid 53 that projects above the upper housing roof plate 27. Within the housing 26 there is positioned a compressed balloon 57 that includes mounting to a nozzle 59, with a piercing spike 58 positioned medially of the nozzle 59. A helium compressed gas cylinder 55 is mounted within a yoke 56 that in turn is mounted to the nozzle 59 and piercing spike 58, whereupon projection of the cylinder 55 upwardly by actuation of the balloon solenoid piston 54 that in turn is actuated by a conventional solenoid upon closure of the first switch through the first switch rod 37, the compressed gas cylinder is punctured by the spike 58, wherein the compressed gas is directed through the nozzle 59 into the balloon 57, wherein an expansion of the balloon 57 inflates the balloon and rises upwardly as a visible signal, in a manner as illustrated in FIG. 12. A balloon tether line 61 is wound about a balloon spool 60, whereupon the tether line 61 is secured to the yoke 56, whereupon rising of the balloon 57 tethers the balloon relative to the upper housing 12 to the balloon tether line 61. 
     The diagrammatic illustration of FIG. 2 illustrates the orientation of each switch and the respective contact members. The phantom representation indicates by way of example that the remaining switches are merely positioned in series with the transmitter organization and operative in a like manner. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, 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.
