in marine accessories such as life preservers, ring buoys, and similar objects that are provided with illuminating means for facilitating locating and retrieving such objects, particularly under conditions of reduced visibility.
Illuminated accessories of the foregoing character have heretobefore been constructed with the illuminating device attached by a cable which allows such a device to be separably attached to such an accessory and to become operable responsively to the launching of the accessory for enabling detection and recovery of the assembly in darkness or conditions of reduced visibility. This type of illuminated accessory presents the problems of damage to the illuminating device, the separation of the device from the floating object and the failure of the device to mark'the exact position of the said floating object as well 'asimparting difliculties in the casting or launch ing of the assembly.
An important object of the invention is to pro- 'vide a marine accessory, such as a life preserver. for example a ring buoy with lights, normally extinguished, but automatically illuminated to act as marker lights when the buoy is afloat, the said lights being housed in the fioatable body of the life preserver and disposed so as to assure one of the said lights being visibly operative independently of the floating position'of the said life preserver. I e
A further object of this .mvention is to provide a ring buoy with marker lights that are permanently housed within the body of the buoy and thereby are protected from physical damage resulting from sharp contact of the buoy with the surface of the water onto which the buoy is thrown, or with other bodies. I I
A further object of this invention is to provide ring buoy marking lights permanently housed within the buoy and so arra'ng'ed as to assure full visibility thereof, and which will automaticallybe illuminated responsively to l'aunching of the buoy.
A further object of this invention is to provide a ring buoy with marker lights that will identify the exact position of the buoy when that buoy is afloat. V v l I A still further object of this invention is to provide a light for a ring buoy-that will become illuminated and fully visible independently of any position of the body of the buoy when floating.
Other objects and advantages of this inv'h tron will become apparent as the descriptidn prm T ceeds and the features of novelty will be pointed out in particularity in the appended claims.
The invention be understood more readily by reference to the accompanying, drawings, which show the construction of an illustrative embodiment of the invention, and in which:
Fig. i is an elevation ofra. ring buoy embodying the improvements of "the present invention; "the view showing the buoy in an .inoperating position. v
such as a position of storage;
Fig. 2 is a vertical-section through the buoy and one light unit taken on the-line E IT- of Fig. 1, looking in the direction of the arrows;
Fig. 3 is a vertical section taken on the line:
IIIIII of Fig. 1-, looking in the direction of the arrows;
Fig. 4 is a vertical section through a. light and a portion of the buoy astaken on line IV=-'-IV of Fig. 2, looking in the direction of the arrows:
and
Fig. 5 is a. fragmentary vertical sectional view. partly in elevation, ofone end of either of the light units and surrounding portions ofya ring buoy, showing the switch closed for illuminating the light in response to floating buoy subsequent to launching.
In the drawings, wherein for the purposes of illustration there isqshown a preferred embodiment of the improved construction of the pres-i ent invention, the ring buoy is indicated genera-lly by reference numera-l 1 and includes a body '2 of buoyant material and a protective covering 3. The ring buoy -l is provided with two diametrically opposed and oppositely facing pockets I and 5, each extending through the covering-3 on one side of the buoy and entirely through the material 2-.
Each pocket 4 and 5 contains an identical light unit or assembly, indicated generally by '6, having a lens portion exposed to View at the open side of the pocket and with the perimeter of the-lens substantially flush with the. body f the buoy,
eachlight being exposed onya' different side sureiace of the ring buoy and diametrically opposite with respectto the whole buoy so as to retain the balance of the ring buoy.
Each light unit or assembly 6 is composed ofa cylindrical casing-1 open at one end and :closedtat the other or base end defining abattery chamber 1a. The open end of easing -l terminates in terior threads as at-8. Arcua'teleh's 9 i provided with a sense no dii'ectd in'wardiv er the sorta. are and havihg threads as the iii-tenor position of the extending between gaskets l2, includes socket l9 carrying an electric lamp or bulb 20. The electrical circuit includes conductor 16 terminating at one end in spring 2! contacting the reflector Exteriorly of the casing 1 but integral with it and approximately parallel to'the casing I and generally in the same plane as conductors I5 I and I6 (as indicated by lines IIII and III-III of Fig. 1) is the switch device including mercury barrel 22 approximately circular in cross-section having mercury chamber 23 which is approximately in the shape of a frustum of a cone with the larger end toward the lens and the smaller end toward the closed end or base of the casing Mercury chamber 23 contains the exposed ends 15a and 16a respectively of conductors l5 and I6 which are spaced slightly apart at the smaller end of the mercury chamber 23 and a small quantity of mercury 24.
The closed or base end of the casing 1 has ex-- terior screw threads 25- mating with threads on the interiorof the annular retainer ring 26 to which it is removably secured. Annular retainer ring 26 has an integral flange 21 that overlies a stepped'annular recess cut in the buoyant material 2 adjacent to the pocket, 4 or 5, and is secured thereto by screws 28. The retainer ring 26 is placed under the outer covering 3 as shown in Figs. 2 and 3.
When the buoy is suspended in a vertical plane, that is to say in storageposition as shown in Fig. 1, the mercury 24, as shown in Figs. 2 and 3, flows by gravity away from contacts I5a and H511, thus opening the switch and preventing discharge of the batteries. When the buoy is disposed in a horizontal plane, as would be the case when it is afloat, the two light units'or assemblies 6 will be in vertical positions, one with the lens up, the other with the base end and retaining ring 26 up. The mercury 24 in the light unit having the lens up will fiow to the smaller end of the chamber 23 and close the space between contacts [5a and 16a completing the electrical circuit and lighting the lamp while the mercury in the other or base end up unit will rest in the larger end of the mercury chamber whichever side of the buoy is above the surface. Additionally, it may be seen that the light unit with the lens on the underside of a floating buoy forms a reserve light that'may be-put in operation by the inversion of thebuoy to'prolong the time of illumination beyond the life of the battery of one light unit.
v It is to be understood that the form" of the invention herein shown and described is a preferred example of the same and that various changes in size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the following claims. Having thus described my invention, what I claim as new and wish to secure by Letters Patent 1.
