Complete Specification Accepted, 9th Mar., 1889
ALFRED CHRISTOPHER BELL of Main Road Bexley Heath in the County of Kent,
Plumber &c. do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in the Construction of Ball or Float
Valves for the admission of liquids into and out of Cisterns, being very simple more
compact in form and more complete in action than anything of the kind heretofore.
The drawing shows the improved Valve in section and the different parts are
marked A. B. C. D. and E. Part A is an ordinary diminishing Nipple, the large end
is for a boss or a pipe to screw into in the usual way. The small end is turned taper
part of the way so as to form a Valve Seat. This end of the nipple is screwed into
part marked B which is a square or oblong Box or Shell, the bottom end quite open.
This part B has a hole at the back and shows part A screwed into it. This box has
two other holes one through each side as shown at part E. Part C is an elbow lover
and float, this elbow lever has a hole through same corresponding with the two holes
in part B, which has a split pin or an equivalent fitted in through both sides of
Box and lever. This pin is marked E. which forms the fulcrum for part C to
work on.
That part or side of the lever that faces the nipple is recessed, in which
recess an indiarubber disc is fitted, either with any suitable cement, or a Screw Cap,
the disc faceing centrally the opening in nipple, thus forming the Valve. Now I
wish it understood that I do not bind myself to any particular mode of construction,
as some parts may be brazed instead of screwed, nor any particular shape, as the
Box or Shell may be octagon, or round as decided on in making. Nor do I bind
myself to any particular material in the construction, but prefer Brass and indiarubber.
I am likewise aware that the lever may be a double elbow lever, and the Seat of
Valve placed at top of Box, or the lever may be formed as a Cam. But what I do
claim is Ball or Float Valves constructed on the principle as I have shown in
sectional drawing, whereby I do away with Washers, Cup leathers, Pistons,
Plungers, Rams &c. I economize time in the construction and a great saving in
material.

page_text: 1, ALFRED CHRISTOPHER BELL Main Road Bexley Heath, Kent, Plumber &c.,
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:-
This invention has for its object improvements in the construction of Ball or
Float Valves, for the admission of liquids into and out of Cisterns, being very
simple, more compact in form and more complete in action than anything of the
kind heretofore. The drawing filed with the Provisional Specification shows the
improved Valve in section, and the different parts are marked A. B. C. D. and E.
Part A is an ordinary diminishing nipple, the large end is for a Boss or Pipe to
screw into or onto in the usual way. The small end is turned taper part of the way
so as to form a Valve Seat. This end of the nipple is screwed into part marked B,
which is a square or oblong Box or Shell the bottom end quite open, this part B has
a hole at the back and shows part A screwed into it. This Box has two other holes
one through each side as shown at part E. Part C. is an elbow lever and float.
This elbow lever has a hole through same corresponding with the two holes in
part B, which has a split pin or an equivalent fitted in through both sides of Box and
lever. This pin is marked E, which forms the fulcrum for part C. to work on.
That part or side of the lever that faces the nipple is recessed, in which recess an
indiarubber disc is fitted either with any suitable Cement or a Screw Cap, or the end
of the lever may be left as a flat tougue and a piece of indiarubber tube pulled
over it, facing centrally the opening in nipple, thus forming the Valve, whereby
I do away with, Washers, Cup leathers, Plugs, Pistons, Plungers, Rams &c.
I economize time in the construction and a great saving in material.-Now I
wish it understood that I do not bind myself to any particular mode of construc-
tion, as some parts may he brazed instead of screwed, nor any particular shape
as the Box or Shell may be octagon or round, or the nipple end and the Box or
Shell marked B can be cast in one piece and the Valve Seat fitted in or turned
afterwards, nor do I bind myself to any particular material but prefer Brass and
indiarubber. I am likewise aware that the lever may be a double elbow lever and
the Seat of the Valve placed at top of Box or the lever may be formed as a Cam.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1st. The Box or Shell as shown in sectional drawing filed with the Provisional
Specification and the Valve arranged as described, acted upon by the side of end of
lever.
