JOHN HYLABD, OF ST. KILDA, VICTOBTA, AUSTRALIA.

LIFE-SAVING APPARATUS FOR USE AT SEA.

Application filed May 9, 1925.

To (ZZZ whom it may concern Be it known that J 01in HYLAKD, subject of the King of Great Britain, residing at 62% Clyde Street, St. Kilda, in the State of Victoria, Commonwealth of Australia, has invented certain new and useful Improvements in and Relating to Life-Saving Apparatus for Use at Sea, of which the following is a specification.

This invention relates to life-saving apparatus for use at sea to indicate at night the position of a person in the water.

My invention provides means whereby an individual floating in water may carry or support a light of sufficient brilliancy to at once indicate his or her position.

An object of the invention is to provide means to enable the apparatus to be made ready for operation by a simple manipulation of the hand, so that when the person enters the water the apparatus will produce an effective illumination above the water line. I

A further object of the invention is to provide apparatus which is simple in construction, easy to manipulate, may be manufactured and installed at a low cost, and is so durable that its life is considerable under the usual and all conditions atsea.

In order that my invention may be the more easily understood, reference will be made to the accompanying sheet of drawings in which- 1 Figure 1 illustrates the container, the float guide, and the strap or band, hereinafter described, in position on a wearer.

Figure 2 is an enlarged view showing the container, the guide, the strap or band, and the lamp, hereinafter referred to, a portion of the strap being broken away.

Figure 3 is a sectional view of the container and guide.

Figure 4.- is a sectional view showing only the guide and a float therein.

Figure 5 shows the bottom of the container and illustrates the locking means for a removable. lid disposed thereat.

Figure 6 shows in section a portion of the float guide.

Figure 7 illustrates in section ona larger scale, means for fixing the lamp to the strap or band.

Figure 8 is a diagram of the wiring hereinafter referred to.

In the accompanying drawings, 1 is a tubular strap or band of suitable material,

Seria1 No. 29,050..

preferably strong canvas, adjusted to form a loop adapted to bear on the neck and body of wearer assho wn by Figure 1. The sir'ap is preferably composed of-two mem-- hers or layers as indicated by Figure 2. The ends of the strap or band are fastened to each side of a container 2, preferably by pin 3, which passes through lugs 4 projecting from the sides of the container, which is constructed of suitable metal. In the container is disposed a battery 5 maintained in its inserted position and protected againstwater by aremovable lid 6 having a recess 7 at its edge holding a suitable packing contacting with the lower edge of the container 2. I provide locking means for the lid 6 comprising a plate 9 (Figure 5) which when turned on pin 10 engages longitudinal slots 11 in vertical plates 12 integral with the lugs 4 and projecting below the lower edge of the lid 6. The. plate 9 may be turned by a key (not shown) having pins which are inserted in the holes 13 of the plate 9.

The source of light is preferably at the midlength portion of the band or strap and at the rear of the wearers neck. Electrical energy is preferred as the means of illumination, and is obtained from the battery 5 disposed within the container 2 and conducted from the contacts 14: and 15 disposed in a suitable insulatingmaterial, such as an insulating cement 15 placed at the top of the container 2 and held by the lid 16 secured thereto, said contacts cooperating with contacts projecting from the battery as shown by Figure 3. The current flows from the contact 14 along the wiring 17 which'is passed through the holding staple 18 fined tothe top of the lid 16 and enclosed in insulating cement 16 thence long a member of the strap 1. At this point both members are connected in any suitable manner, preferably by stitching thread. Upon reaching the end of the strap, the wire 17 is led through one member thereof, and upon reaching the midlen-gth portion, the wire is passed through a hole 17 in a plate 19 (Figure 7), after which it is turned around and connected to the circular contact 20 or socket cooperating with the contact 20 of the lamp 21. The contact 20 is supported by and fixed to the plate 19, which is disposed within a chamber 22 provided in "the strap 1 between the midlength portions of the members thereof. To add to the rigidity of the strap at this point, an internal stiffening plate 23 of leather or other suitable material is disposed in the chamber 22. The lamp 21 is provided with a wire or other suitable guard 23. From the contact 15, the wiring 24 is led to one of the parallel contacts 25 disposed within a suitable insulating ceinent'at the top of a float guide 26 integral with or fixed to the container 2. From the adjacent contact 25, the wire 25 is led through the insulating cement 15 and is also passed through the holding staple 18, from which it is carried up through into the other member of the strap 1, thence along through said member to the midlength portion where it is passed through the hole 26 of the plate '19 and also through the stiffening plate 23, the wire being finally connected to the contact 27 embedded in the insulating cement 28 at the bottom of the circular contact 20, the contact 27 cooperating with the contact 2".

The circuit formed by the described connections is closed and broken by an automatic switch, comprising a float 29 disposed within the guide 26, and resting under normal conditions upon the top of a screw plug hereinafter described. The float 29 has strengthening plates or heads 30 and 31 at its ends. The plate 30 is provided with a connecting contact 32 which when the float 29 rises passes between and strikes the spaced apart contacts 25.

The float 29 may be fastened in its lowest or circuit breaking position by a pin 33 which passes through an orifice in the guide 26, and enters an orifice in the float 29 and may be provided with a pull cord 33 In lieu of such pin, a circumferential groove 34 may be made in the float (Figure 4) and at each side of the guide 26 inclined tubes 3 L may be provided in the integral blocks 35. In each tube 34* may be disposed a ball 36 of metal or other suitable material. VVhen'the container 1 and with it the guide 26 are turned upside down, the balls will run along the tubes 34E and engage the groove 34:, and by doing so holdthe float 29 preventing contact being made between 32 and 25.

The lower end of the guide 26 is closed by a screw plug 37 (Figure 3) engaging the internal thread 38 (Figure t) at the bottom of the guide 26, and provided with a central opening 39 in which is disposed two vertical arms 40 supporting a flat circular plate 41 forming a guard to prevent the fingers or material being inserted through the opening to operate the float 29 after unauthorized removal of the pin 33.

I provide air-releasing means embodied in holes (Figure 4) of suitable dimensions made in the wall of the guide 26 between the upper and lower ends thereof. Said holes allow the escape of air when the float 29 rises, and are positioned to allow sutflcient space between them, and the contacts 25 to ensure an air lock to keep thewater from meeting the contacts 25, the upper portion of the guide being closed against the escape of air.

When the apparatus is not in use, the

closing of the holes 42 by the accumulation of matter may be prevented by a paper or the like seal (not shown), which may be cemented to the sides of the container and guide and easily removed when necessary. When the container and other parts of the apparatus are not in use, they may be enclosed in a suitable or light envelope or envelopes to prevent deterioration.

- In operation, the strap or band 1 is placed around the neck, the container 2 resting against the front of the wearers body, and is preferably within the life belt 43 shown by dotted lines in Figure 1. After placing the strap or band in position, the next step is to pull the pin 33 out of engagement with the float 29. lVhen the wearer enters the water, the latter passes through. the opening 39 of the screw plug 37 as indicated by the arrows (Figure 6) and forces the now free float 29 upwardly, simultaneously forcing the excess air within the guide 26 through the holes 42. As the float reaches its limit of upward movement, the connecting contact 32 makes contact with the spaced apart contacts 25, closing the circuit, the current passing from the battery 5 through the described circuit connections. The lamp may now show a continuous light for a lengthy period. Should the water be rough and the wearer be tossed about, the container may rise briefly out of the water, allowing the float to drop and break the circuit; but when the container and guide again enter the water, the circuit is closed, so that an intermittent light is provided. The frequency of illumination will, however, be suflicient to indicate the whereabouts of the person in the water under all conditions at sea and enable a prompt rescue to be effected.

It is to be understood that all metal parts which come into contact with the water are to consist of a metal of non-corrosive nature.

It is obvious that the container 2 may, in lieu of being carried by the strap or band 1, be carried by or attached to any type oi life-buoy or life belt and the like. In any case, the arrangement must be such that the open end of the float guide faces downward and is submerged when the apparatus is in use.
