NON-SINKABLE BUCKET Filed Dec. 3, 1962 FIC-5.3.

FIGA. 8

mvmran United States Patent O 3,170,589 NoN-SINKABLE BUCKET Filed Dee. 3, 1962, Ser. No. 241,714 Claims. (Cl. 22h- 66) The present invention relates to an unsinkable bucket and method of manufacture for same. The principal advantage of the invention is that it cannot be lost by either being accidently or otherwise dropped overboard from a boat, dock, etc., where it may be used for the purpose of hauling water aboard, washing down etc. It is a well known fact that a great number of buckets are lost, either accidently dropped overboard or by losing the hand line to which the bucket is ordinarily attached.. When a bucket is manufactured as hereinafter specified, the bucket will not sink regardless of which material a bucket is normally manufactured from. In other words, a metal bucket will not sink any more than a plastic bucket for the reason, when the bucket I is dropped overboard, regardless of the position in which it may land on the water it will roll over and go bail, or upper end down, thus trapping air in the bucket which causes it to float bottom up with several inches of the bucket floating above the water level.

Another important advantage of the bucket is, that it can be very economically manufacturedwith a double bottom thus providing an air space between two bottom f surfaces and comprising a :sink proof bucket with very little additional manufacturing cost.

Another important Vadvantage of the invention is that a rubber or plastic cap can be snapped over the bottom of a conventional bucket thus providing the advantage of a sink proof bucket, as called for in the specification and claims.

Another advantage of the present invention is that a hollow rubber or Styrofoam form etc., can be attached on either side of the bottom vof a conventional bucket thus providing the advantage of a sink proof bucket' as hereinafter shown and described on the drawings and specifications.

Another important advantage of the present invention is that the bucket can be manufactured to incorporate the features called for in the claims and specifications, or that iioat means of rubber, Styrofoam, plastic, etc. can be attached to the bottom of the bucket either on the inside or the outside and comprise an unsinkable feature of the present invention, that is, an unsinkable bucket.

Another important object and feature of the present invention is the provision of an improvement in buckets generally and whereby the bucket can be tossed overboard accidently or otherwise and not lost by sinking, as the float means attached to the bucket bottom simply causes it to' roll lover trapping air within itself and it therefore oats above the surface of the water, supported by the air within the bucket.

Other objects and advantages of the invention will be apparent as the specification, description and claims are understood.

It is to be understood that the preferred method of manufacture of the bucket would be as follows:

Referring to the drawing,

FIG. l indicates the top view of an improved bucket with a double bottom as called for in the specifications.

FIG. 2 is a sectional view taken on the line 1 1 of FIG. 1, looking in the direction indicated by the arrows and illustrates the outline of a bucket with a double bottom comprising an air chamber A, it is otherwise of conventional construction.

FIG. 3 is a sectional view of a bucket comprising the invention by incorporating an air space A in its bot- 3,179,589 Patented Feb. 23, 1965 ice . 2 v tom. The sectional view isv'also taken on the line 1--1 of FIG. 1, but shown in a vertical bottom up position,

indicating a nal floating position when the bucket is e tossed overboard and comes to rest-in a bottom up position with air trapped within the bucket which causes the bucket to rotate and float on the line 3-'-3 bottom up with the bottom well above the water level.

FIG. 4 indicates a partial sectional view of a bucket with a double bottom. The double bottom being formed by snapping a rubber or plastic cap etc., over the bottom of the 4bucket thus forming an air space between the bottom of the bucket and the cap member.

FIG. 5 indicates a sectional View of aconventional bucket to the bottom of which, is attached a Styrofoam float member. Thus it is to be understood that the Styrofoam is glued to the bottom of the bucket and firmly attached thereto, `to prevent loss of the Styrofoam float member when the bucket is in use.

It is also to beunderstood that the Styrofoam form can be any preferred shape and can be attached to either fthe inside or the outside surface of the bottom of the bucket.

FIG. 6 indicates a partial sectional view of a conventional bucket to the bottom of which, is attached-a hollow float member. The float means can be attached on either side of the bucket bottom.

Referring to FIG. 1, assuming that in normal operation .the bucket is used aboard a yacht or small boat etc. and is normally provided with a lanyard or hand line, shown attached to the bail 16 and designated by the numeral 17.

It is to be understood that when the bucket is thus tossed overboard by the attached lanyard, the bucket will land on its side and normally sink to a position indicated by the line 18-18. Since the conventional bail 1 6 and larger end of the bucket has .no support it immediately sinks down by tipping over to the broken line indicated at 19, thus trapping a considerable amount of air in the bucket as indicated at 20. As the bucket rolls over still more to the broken line indicated at 21, the upper edge ofthe bucket 23 cuts 0E air escape at the water line 18 and thus seals olf the air trapped in the bucket.

Referring to FIG. 3, the bucket continues to roll over `to a complete vertical position as shown in FIG. 3. The bucket normally floats at line 3 3 because the air trapped in thel space 4 supports the bucket well above the surface of the water.

It is to be understood that this bucket as shown and described, under any circumstances will always trap suiicient a-ir within itself to float well above the surface of the water, due to the novel construction and floating arrangements provided by the invention.

Referring to FIG. 4, a partial sectional view, 5 indicates a rubber cap snapped over the bottom of the bucket thus trapping air between the bottom 7 and the rubber diaphragm bottom 8 providing an air chamber 6. In op eration the bucket will perform the same as the bucket in FIGS. 1, 2, 3 but with the further advantage that the bucket has a soft bottom and when dropped on deck of a boat, ship, etc., it will not mar the deck and provides a cushion as Well as an air chamber 6 in the bottom of the bucket.

In FIG. 5 the bucket 9 has a bottom 10 with a styrofoam lioat 11 attached to the bottom of the bucket and in operation the performance is the same as the bucketi as shown in FIGS. 1, 2, 3, 4.

In FIG. 6, 12 indicates a bucket shown in partial secl tion with a hollow rubber or plastic oat member attached to the bottom. The performance of this bucket arrangement is the same as the bucket previously described in the operation of the bucket shown in FIGS 1, 2, 3, 4, 5, etc.

e e Y A i d Y It is to be understood that Various modications may Lbe -rnade in the `size and form of Vthe bucketV and/or the oat means attached in the bottom ofthe bucket most portion and a Weight in the form of a bail attached to its uppermost portion which causes said bucket to turn upsidedown Whensaid bucket is dropped into Water or other huid.

c 21A non-sinkable bucket comprising a relatively heavy bail attached to its rim and a relatively lightfloat means v attached or formed in the bottom of said non-sinkabler bucket to cause said bucket to rotateA bottom up when dropped overboard into water.

` 3. Anon-sinkable bucket including aroat means at-V tached to the bottom of said bucket, said bucket also including a weight in the formof abail attached to its upper rim adapted to be capable of causing said bucket to Vrotate bottom up when dropped overboard.v

4.- A bucket comprising angenerally tapered ,Circular metal, form including walls, a first bucket bottom attached to the smaller end of said Walls, a baillattached to the larger end ofjsaid tapered vwalls, a second bottom attached to said rstbottom; said combination comprising a non-sinkable'bucket With an air chamber in itsV bottom, a bail on its'rim and being kbalanced to rotate bottom up when floated. o Y

5. A non-sinkable bucket. comprising a generally partial conical form including taperedrwalls, la rst bottom attached to thekbottom of said tapered Walls, a second bottom attached to said irst bottom and a bail attached to the upper open end ofsaid tapered walls. f Y
