S. van Daalen, New York, Y. Application July 18, 1942, Serial No. 451,452 1 Claim. (C1. 240—10.68) 2 1 My present invention, in its broad vaspect, has to do with improvements in signal lights of the type especially adapted for use with marine life Saving equipment, and to that end it is construct ed to be securely but removably attached to the person carrying the light in a manner which will permit the light to be elevated on occasion or waved or the like to be visible at a distance, and Brie?y stated, some of the objects and advan tages of my invention are as follows; ?rst, to provide a signal light for life preservers, life saving suits, and the like vwhich is very light in weight, and which is substantially water, mois ture and ?re proof, and of durable yet simple construction; second, to provide dual means of attachment to a life preserver, life saving suit and the like ‘whereby the ‘light may be moved furthermore it is designed to be waterproof and fire proof, .to be easily and quickly operated, ‘and 10 around ‘without likelihood of becoming lost or dis engaged, or may be moved from one piece of life to be exceptionally sturdy and unlikely to get out of order. Especially is my signal light designed saving equipment to ‘another; third, (to provide means whereby the source of illumination will to ‘be used with life saving suits and preservers not become deranged or broken by jars or rough of the type worn by seamen, and to that end it handling; fourth, to provide simple and e?lcient is constructed to conform to standards for equip means for turning the light on and off, and; ment of this type set by organizations having ?fth, to provide a simple, practical, e?icient and to do with marine equipment. handy signal light having no parts likely to be Among the occasions for use of my signal light come deranged or broken, and which can be man may be suggested circumstances surrounding the sinkings of vessels by mines and torpedoes 20 ufactured at relatively small cost.

Furthermore since the person in dis Figure 6 is a view of the casing; tress is likely to be battered by wreckage and by Figure 7 is a detailed top plan view of the clasp; the seas and the like, the signal light must be securely attached to his person, although the means of attachment must be such as will not be likely to cause leaks in the life saving equip ment. In addition to all of these practical re quirements it must be kept in mind that the per Figure 8 is a view of the bulb supporting plate; Figure 9 is a view of the bottom plate which may or may not be used.
