I JAMES FAGAN of Skipton-in-Craven, Yorkshire, Plumber, do hereby declare the
nature of this invention to be as follows, that is to say :-
It consists of a method of constructing and arranging the parts of cisterns used in
connection with water closets so that the cost of production of these cisterns is
greatly diminished while more efficiency in operation is achieved.
To accomplish this I make use of a tap or stop-cock to govern the supply of water
into the cistern, of a kind that closes automatically, such as is set forth in the
provisional specification accompanying my application for a patent bearing date
19th October 1886, and numbered 13,291, with the exception that instead of making
use of the kind of valve therein described 1. preferably use a "ball" valve as this will
operate better when placed in a horizontal position, which is required in connection
with my present invention, than will the former.
It will be seen that when the above-described tap is made use of, only as much
power is required as will open the same against the pressure of water, which is found
in practice to be considerably less than the power required to close the tap against
the same pressure, consequently a smaller float may be employed on the well known
lever arm that operates the supply tap, which as will easily be seen will require a
smaller space to work in and therefore less water to lift it, with the advantages herein
before set forth.
Dated this 23rd day of December 1886.

page_text: COMPLETE SPECIFICATION.
Improvements in Flushing Cisterns and in Ball-cocks for Supplying
the same.
I, JAMES FAGAN of Skipton-in-Craven, Yorkshire, Plumber, 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 that is to
say :-
It consists of an improved method of constructing and arranging the mechanisms
and parts of cisterns used in connection with water closets whereby the cost
of production of these cisterns is greatly diminished while the efficiency in
their operations is enhanced, and in order that this said invention may be more
readily understood I have hereunto appended a sheet of drawings illustrative thereof
bearing figures and letters of reference used in the following description.
7
Fig. 1 is a sectional side elevation of said cistern. Fig. 2 is a top view of same,
and fig. 3 is a sectional top view of the tap or cock thereto applied, while figs. 4, 5, 6,
and 8 are detail drawings enlarged scale hereinafter referred to.
The object above set forth is attained by the application of a tap or stop-cock a,
which governs the supply of water into the cistern b, of such a construction or
arrangement that by the pressure of water which is to pass through same, said stop-
cock is automatically closed.
The principle of operation of this, stop-cock is the same as that of the one patented
by me on the 19th Oct. 1886 No. 13,291, only slight modifications in its construction
being required in order to facilitate its application.
These modifications consist of making said stop-cock a so that the coarse screw c
shall be in a horizontal position when in use and a ball d if desired may be used in
place of the valve d¹.
The outer ende of the spindle on which is formed the coarse screw c is made with
its outer surface notched or serrated so that small projections of formed on the ball
lever g may enter therein to hold said lever g securely in position when the nut / is
tightened. By this serrated end being employed the ball lever g may be more readily
and accurately adjusted.
The stop-cock a above described, requiring less power to make it operate allows the
use of a less float ball k consequently a less ball or boat cistern 7 may be employed;
and this cistern I preferably construct of sheet metal (as lead) and attach to the
(and on the inner) side of the large cistern b as illustrated by figs. 1 and 2.
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 :-
1. The combination of the stop-cock a constructed and arranged as herein shewn
and described, with the cistern b, the ball lever g and the cistern 7 substantially as
and for the purposes specified.
2. The combination of the stop-cock a constructed with the end e as shewn, and the
lever g with its projections f, with a cistern b and a boat cistern arranged as
described, substantially as and for the purposes specified.
