it.
The invention relates to appliances in which valves are used to control the flow
of fluid through the agency of a float acted on by a liquid the level of which varies
in direct or inverse proportion to the speed of flow of the liquid past the valve, and
is specially applicable for use in apparatus in which high pressures are used such
as refrigerating apparatus steam generators and stills.
The object is to provide a float which shall have sufficient buoyancy when
floating in the liquid to actuate with ease and certainty the valve to be controlled,
and yet have ample strength to resist any pressure to which it may be subjected.
The invention consists essentially in constructing the float of a number of cells
of metal glass or like rigid material, and in binding the whole together by a
suitable envelope or attachment. I find in practice that a number of hollow
metal spheres bound together by a wire gauze envelope answer well in practice,
but it will be obvious that floats under my invention may be constructed in
many ways.

I, FREDERICK NOEL MACKAY of 85 Commercial Road Lambeth, Engineer do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:

DESCRIPTION OF THE DRAWINGS,
Figs. 1. 2. 3. 4. and 5 are views part in section and part in elevation of several
modifications of floats constructed in accordance with my invention.

piece and drawn together by a screw bolt e.
It will be obvious that numerous modifications of floats having the essential
features of my invention may be made,
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
First. Cellular floats substantially as set forth.
Second. The combination of the hollow spheres or cells of rigid material within
the containers or envelopes for the purpose set forth.
