Claims.-

This invention relates to new and useful improvements in a marine safety light.

More specifically, the invention proposes the construction of a marine safety light character-' ing mechanism that the flashlight may be conveniently moved from an operative vertical position over one shoulder to an inoperative upside down position over the other shoulder merely by pulling on a lanyard used for supporting the flashlight on the body. V

The invention further contemplates the. construction of a safety light as mentioned which is characterized by a vest adapted to be worn under a life preserver or over a life saving suit, a batten mounted on and projecting from said vest above a persons head, and a flashlight of a specific construction adjustably mounted on said batten.

More specifically, it is proposed that the flashlight have a make and break mercury switch which will cause the flashlight to flicker while a person is being tossed about on the waves at sea.

Another object of the invention resides in so constructing the flashlight that it has globe lens at the top through which the light is visible in all side directions.

Still further the invention proposes certain means for mounting the flashlight on the batten so that it may be supported inan upright position or in various pivoted positions, including positions all the way down to an upside down position. Moreover, it is proposed to so construct and arrange the make and break mercury switch that the flashlight will flicker when in the vertical position and in all positions well above the horizontal, that in the horizontal, or substantially horizontal position, the light will be continuous, and in the upside down position the flashlight will not be lit.

The invention contemplates so constructing the supporting means for the flashlight that a wearer floating on the sea may easily adjust the flashlight to its various positions so as to give out the signals desired.

The invention contemplates a particularly simple construction of the vest so that a person-may quickly don the same, as required.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the appended claims in which the various novel features of the invention are more particularly set forth. 4

A mercury switch 69 is mounted within the bottom end of. the insulation bushing- 59- and: contacts the centralend contact 61- onthe top; end ofthebattery cells. 44. A spring 62 is' also mounted within-the insulation bushing 59 and contacts the topof the mercury; switch 59' and the-end contacts 63 of the lamp 51 The mercury switch- Sfl is' of the make break variety and includes; atubular: insulation member 64 supporting a cap The cap 65 makes an' electrical tion member 64 l and which terminating a short-distance from the cap 66. A small mass ofmercury 68 is contained within the switch 60 and is arranged toclose an electric circuit through 68 contacts the shell-Gland thecap-fifi, as shown in- Fig. 12. The mercury mass 68 is of a relatively small size so that when the flashlight bobs 65 at oneend-and-a cap 66:

the switchwhenever the mercury around the mass of mercury will move about within the switch and make and break the electric circuit to cause the lamp to flicker. However, when the switch 50 is in any angular position ranging between the vertical and the substantially horizontal with the lamp directed upwards, the mass of mercury will maintain a relatively stationary position and will continuously maintain the circuit through the switch, causing the lamp to be continuously lit.

A conductor strip 69 is provided for completing the electric circuit and comprises a metallic member 10 extending along the sides of the battery cell 4| and which is provided with longitudinally spaced clips H for gripping the sides of the cell 4|. One end of the metallic strip 10 is formed with an offset portion 12 which extends along the bottom end of the cell- 4! and which is urged to continuously make electric contact with the cell by the spring 42. The opposite end of the metallic strip 10 is formed with an offset end 13 which is arranged to engage the flange 56 of the lamp support 54 to complete the circuit through I the shell contact 58 of the lamp 51'.

In Fig. 6 a wall clip 18 is shown for support ing the flashlight in an inoperative upside down or an operative vertical position. This bracket houses a strip of material 19 adapted to be at tached to a wall and provided at its bottom end with a forwardly extending flange 80. Spaced spring clips 8| are mounted on the strip 19 and are arranged to encircle the casing of the flashlight 2!. In Fig. 6 the flashlight 2i is illustrated supported upon the wall bracket in an inoperative upside down positionv by the dot and dash lines 2l.

However, it is possible to reverse the position of the flashlight 2i permitting it to assume an operative position in which the mercury switch 60 will be closed, causing the lamp n 51- to be illuminated.

The-operation of the device is as follows:

To use-the flashlight 2.! as a safety light the wearer attaches the clips 48 and 49 of the lanyard 4! to the members and 46. The lanyard 41 is; then engaged about the wearers neck. with thering located to the front of the wearer. The free end of the rope 5% is then passedrabout the wearers waist. and knotted. in position to retain the ring 50 in position between the lan- .yard 41 and. the rope 5.1. In. this position. the lanyard 41. is free to be slipped through the ring,

permitting. the flashlight 2.! to assume the operative position .over the wearers left shoulder, asshown in Fig. 1. However, to extinguish the .flashlightll it is merely necessary to pull on the lanyard 41, causing the flashlight to pass around the back of the wearers neck to assume an. inoperative upside down. position over the wearers right shoulder. Thislatter position is to the inoperative position will be clearly understood.

The marine safety light, in accordance to the form of the invention illustrated in Figs. 1346 inclusive, includes a flashlight 2W which has a casing 40 adapted to receive the battery cells M. An end portion of the casing 453 is provided, on opposite sides. with tubular extensions 14 sup porting metallic loops 25. The remote end of the casing 40 pivotally supports .a loop d5. A lanyard '41 has spring clips '48 and 49 at its ends. These spring c ips are so arranged that one is engaged with the loop d6 While the other is engaged with the loop d5.v Thus the lanyard 4'! may be engaged about ones neck, as clearly illustrated in Fig. 13, so as to support the flashlight 2i across the wearers left shoulder.

.The lanyard -41 carries a ring -50 adapted to engage one button of a jacket of a user of the marine safety light, as clearly shown in Fig. 13. With this arrangementthe lanyard 41 may be shifted so that the marine safety light extends first across the back of the wearers shoulder and then across'the right hand shoulder. It is then in a downwardly tilted inoperative position similar to the arrangement described relative to Fig. 1.

It is provided with an offset end E3 contacting, the lamp holder M A globe lens M is threadedly engaged into the top of the cap 52 and surrounds the top end of the lamp 511. A gasket 15 is disposed between the contacting edges of the globe lens l4 and the cap'52 forming a waterproof joint. The cap 52* has lugs upon which a wire guard 16 is mounted which extends over the globe lens M In other respects this form of the invention is iden tical in construction and operation to the previous form.

The marine safety light, according to the form of the invention shown in Figs. 17to 21 includes a vest 15 adapted to be worn under a life preserver l6 or over a life saving suit, the latter not being illustrated on the drawings. The vest I has a vertical pocket I! on its back portion. A batten i8 is supported in and projects from the pocket H to a point above the head of a person wearing the life saver or life saving suit (as illustrated in Fig. 17). A swivel joint i9 is located on the top portion of the batten IS. A flashlight 2'! is supported by the light holder 20, as hereinafter more fully described. The

construction is such that the flashlight .2l'v may be placed in a horizontalposition, as illustrated by the full lines in Fig. 20, or in the vertical positions illustrated by the dot and dash lines 2|". The flashlight 2| is of a construction to'be waterproof, that is, not to be efiected if submerged. It is also of a construction so as'to flicker when in the upward vertical position 2l",- and to be continuously lit when in the horizontal position, and to be completely out when in the upside down vertical position 21, similarto flashlight 2! previously described, which as already known has a mercury make and break switch.

The vest I5 is preferably made from canvas. It is provided with a back piece 23 preferably of double layer material sewed together by stitches 24 along its edges and by the stitches 25 which are extended inwards from the top to form the pocket I'l. The back piece 23 is provided with straps 26 attached to its bottom corners. These straps may incircle ones body to form the waist strap of the vest. A pair of diagonal straps 21 are attached to the top corners of the back piece 23 and are adapted to extend over the shoulders of a wearer to the front. These straps 21 are connected with-each other and with a main central strap 28 which extends downwards and is adapted to be attached or to be tied to the straps 25. It should be noted that the vest is of exceptionally simple construction and is well suited for the purpose intended. However, the vest could be made more elaborate with sleeve openings and other features, if this is desired.

The batten i8 is in the nature of a strip of wood, preferably 4" thick, 1 wide, and some 20" high. This height is suff cient for the batten to project above the head of a person provided with said marine safety light. The batten I8 is held from accidentally comingout of the pocket H by a fastener 29 engaged through the layers forming the pocket I! and through an aperture 30 formed in the batten.

The. swivel joint l9 comprises a bracket 3| which is secured on the top of the batten l8 by rivets 32.

This bracket 3| has a forked upper end between the finger of which 2. lug 33 from th light holder 20 extends. A wing nut clamp screw 34 extends through the fingers of the bracket 3| and through the lug 33 for swivelly connecting these parts. The wing nut may be loosenedand then-the light holder may be swung upwards and downwards. The wing nut 34 may be tightened to clamp the light holder 20 in a selected fixed position.

The-light holder 2! comprising encircling strips 35 adapted to engage around the center of the flashlight 24. At one side the strips 35 have the lugs .33. At the other side, they are provided with a 'pair of parallel end. portions 36 through which a wing nut clamp screw 31 passes. The wing nut clamp screw 3? may be tightened to cause the strips 135 to tightly clamp and hold the flashlight 2!. It is onlyenecessary to loosen the wing nut and screw 34 to pivot-the swivel joint 19 to selected positions, as indicated in Fig. 20. The

wing nut and screw 3'! is not disturbed after the flashlight is mounted in position. The operation of the device is :as follows:

During an emergency when one must don a life preserver or life saving suit and take to the water, the vest i5 is also donned. The vest;supports the batten 18 which in turn indirectly adjustably supports the flashlight 2!. The wing nut andscrewtfi is loosened and the flashlight 2| is .moved to a position .in which .it .is upside down. The wing nutand screw 34 is then tightened. When the wearer wishes to attract the atte'ntion of a rescue party he reaches up and loosens the wing nut and screw 34 and pivots the light holder 20 to a position in which the flashlight 2i is vertical. The'lamp of the flashlight will now flashbecause the circuit through the lamp will be periodically made and broken by the mak and break mercury switch thereof. If a steady light is desired the wing nut 34 is again loosened and the flashlight is placed in a substantially horizontal position in which the mercury switch will maintain constant contact.

While I have illustrated and described the preferred embodiments'of my invention, it is to be understood that I'do not limit myself to the precise constructions therein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States LettersPatent is:
