LIFE uoy. I I

Application filed October 24,1925, Serial no. 64,672,.and in]N'ew Zealand J'iil-y l, 1925,

' This invention relates to life buoys of the usual circular form and in whichthe buoy is'divided into one or more'water-tight compartments stuffed with kapok and covered,

with a specially -.p.repared' canvas or other suitable covering. I

The object of this invention is to provide a buoy of great buoyancy which will be rigidly constructed and in which the maximum strength, lightness and utility for lifesaving purposes is obtained.

According hereto, an additional-circular pad passes around the circumference of the buoy and covers the circular'edge anda portion of the sidesof the buoy. By means I water-proofsothat should the outer casing become, in any way damaged or perforated" of this the pad will act as a protection to the buoy against rough usage when it is being handled and will also afford additional buoyancy. The pad is preferably of kapok 4 in order to be as buoyant as possible. The

rope or cord aroundthe buoy is 'now attached to the outside pad in loopsasbetore, A band, slightly longer than the'diameter of the buoy, lies loosely across a diameter so 7 as to give a certain amount of slaekness in order not to afford. any obstacle to a person I getting within the buoy. This will afford resistance to 'a person sinking downwards through the centre ofthe buoy, since such band will provide an additional support, either as a seator as an arm support, a feature of especial value should cramp occur. The invention will be illustrated in the accompanying drawings, wherein Figure 1, is a plan of the finished buoy. Figure 2, is a plan of the frame-work. Figure- 3, is a cross section through a portion of the buoy drawn to a larger scale than any of the preceding views.

Figure 4:, is a plan showing a' mode reinforcement.

Figure 5, is a perspective view of a detail.

Referring now to the drawings, the buoy consists of rings 1 and 2 of cane. Such rings are heldin positionby wooden braces 3 (see Figures 2 and 5) having theirinner and outer edges curved as shown, while .the rings 1 and 2 are secured to suchbraces by nails 4. Between the inner and outer ring layers of canvas 5 and 6, cut in a circular shape,

are secured by'stitching .7' upon the inner sides of the rings 1 and 2. This compartment, formed by the layers 5 and 6. is stuffed with kapok 8 and the upper layer stitched ing of an inner ring,

1 down as the stuffingproceeds, thus forming, a casing for the'kapokQ A circular pad 16 formed, of canvas cover 13 stufiedwith kapok completely encirclesuthe frameZ as suggested by the dotted lines in Figure 2.

O'ver this pad the outer layers of canvas9 space may be stufied' with kapok 11; or, if

desired, merely carried over the layers 5 and 6.

After the inner casing is sewn up 'thebuoy dipped into a water-proofing solution, and after the outerfcasing is sewn-the buoy is again dipped into the same solution, which renders both the inner and outer casing and the stufiing below such outer: casing be. I

and 2 are reinforced by bracing 14 formed of cane bent in theiorm shown and zigzag ging from one ring to-the other andsecured to the r1ng'sbyst1tch1ng15. v T

A band 17, slightly longer than the diameterof the. buoy, is attached to the ropes 18 andlies vloosely'across a diameter so as to i give a certain amount of slackness in order not to afi ord any obstacle, to a person get.-

ting within thebuoyi, This band 17 will afford resistance to a person sinking downwards through the centre offthe buoy, 811166" such band will provide an additional support, either as a seat or as an arm support, a feature of especial value should crampoccur. v v I What I claim is a r 1. In a life-buoy of circular form having water-proof compartn1ents,-a frame consistsupporting saidrings, an inner casing of water-proof material attached up onthe in} ner edges of such rings, said casing-stuffed with a buoyant material, a pad to coverjthev outer ring and extending circuniterentially anouter ring, braces around the-buoy, and an outer casing, of

water-proof material'around the exteriorof the circular pad and the 1nner casing,'substant-ially as described. 1.

2. In a lifebuoy of circula lg I t mightcompartmeuts aninner ing 0t being seured t0 *sid' braces, "a casing of water moot canvas sewn to the inner sides of sald nngs, ssucl mner casing stuffed wlth -=a b'u'0yantmaterial, a pad to 'cm elf'th'e'oiiter ring and extending cireiimferentlally around the buoy and an outer casm'g of Water-proof 'material around the exterior of the c ifcu lal" pad and inner casing, substantially asde- 10 scribed. a

In the li febuoy a's c'lailheel i'n claim a band lying loosely across a diameter of the buoy, substantially as and for the purpose specified.

In testimony whereof, I have signed my name to this specification.
