I, DAVID LIONEL SALOMONS, of Broomhill, Tunbridge Wells, in the County
of Kent, Baronet, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a method of rendering soap buoyant, so that it shall float
on the surface of the water, and it is designed to effect this in such a manner that the
heavy and known compositions of soap with their attendant advantages shall be
retained.
I carry out my invention by forming the cake of soap with a cavity, so proportioned
to the weight of the cake that it shall give it buoyancy. This cavity may be either
left empty or filled with any substance of less specific gravity than water, such as
frothed soap, for instance. The said cavity may be formed within the soap itself or it
may consist of a hollow centre of thin metal or other material with the soap cast
around it.
Again, the soap might be cast in concave halves which could be joined together
by merely wetting them, the float having been placed in the centre first.
I have instanced these methods of carrying my invention into effect, so that its
nature may be perfectly understood; but it is obvious that it might be carried out
in other equivalent methods, so long as the ratio of the cavity (or the light
substance contained therein) to the body of the soap is so proportioned as to render
the same buoyant i.e. to displace a volume of water equal to or greater than its own
weight.

Having now particularly described and ascertained the nature of my said

claim is:-
1st. The construction of a cake of soap with a cavity either empty or filled
with substances of less specific gravity than water so that it shall have buoyancy.
2nd. The construction of such cavity by means of thin metal or other suitable
material, substantially as described.
3rd. The construction of such hollow soap in concave halves, substantially as
specified.
