Complete Specification Left, 2nd July, 1889-Accepted, 3rd Aug., 1889
PROVISIONAL SPECIFICATION.
Improved Method of Flushing Water-closets.
I, WILL WHALLEY COTTAM of 7 Warwick Street Burnley, in the County of
Lancaster, Book keeper, do hereby declare the nature of this invention to be as
follows:-
The invention consists in the utilization of the ordinary earthenware, or other pipes,
as a means of reserving waste or other water for the flushing of closets, without the
aid of Tanks or cisterns.
The invention further consists of a watertight Flap or Valve constructed to fit any
size of pipe the upper portion of the Flap or Valve is left open (thus forming an
incomplete flap or valve) for an overflow. The Flap or Valve is inserted in the
Junction pipe of the closet Trap or closet pan, or other pipe near the closet, the
remaining pipes continuing to the yard trap where all waste and other water is
received.
By closing the Flap or Valve it dams up to the overflow, and thus creates its own
reservoir, which is let off at will by raising the Flap or Valve by means of a Rod or
chain connected from inside the closet.

COMPLETE SPECIFICATION.
Improved Method of Flushing Water-closets.
I, WILL WHALLEY COTTAM, of 7 Warwick Street, Burnley, in the County of
Lancashire, Book keeper, 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 :-
The Invention consists in the utilization of the ordinary earthenware, or other pipes,
as a means of reversing waste or other water for the flushing of closets without the aid
of tanks or cisterns.
"
The Invention further consists of a watertight flap or valve constructed to fit any
size of pipe; the upper portion of this flap or valve is left open (thus forming an
incomplete" flap or valve) for an overflow. The flap or valve is inserted in the
junction pipe of the closet trap or closet pan or other pipe near the closet, the
remaining pipes being continued to the yard trap where all waste and other water is
received. By closing the flap or valve aforesaid it dams up to the overflow, and thus
creates its own reservoir, which is let off at will by raising the flap or valve by means
of a rod or chain connected from inside the closet.
In the accompanying drawings Figure 1 is a longitudinal sectional elevation of a
closet, yard trap and connecting pipes, illustrative of the application of my Invention.
Figure 2 is an end view of the "incomplete" flap or valve, above referred to, and
Figure 3 a modification of same. Figures 4, 5, and 6 show convenient arrangements
for actuating said flap or valve.
In the drawing, B is the closet seat. C is the pan. D is the receptacle. E yard
trap, F are ordinary pipes, communicating from yard trap to closet receptacle where
they are connected by the junction pipe H open at top through which a chain a or
rod passes connecting the flap or valve A to a handle disposed within the closet seat B.
This flap or valve, which is pivoted in any convenient manner, is cut away at b,
Figure 2, to permit of the overflow of the waste or other water contained within the

page_text: pipes F, and is raised, to allow of the discharge of the water, either by lifting a
chain a Figure 1, by depressing a handle Figure 4, a Foot stud or pedal Figure 5 ;
by depressing closet seat; by lifting the hinged closet cover or lid, or by any other
convenient arrangement. In lieu however of a hinged flap or valve I may employ the
valve G Figure 3, open at b, capable of sliding vertically within guides c and which
may be raised from the closet seat in a manner similar to the hinged flap or valve A.
The flap or valve A or G, after being raised resumes its normal position when
employing a rod for actuating same by the action of a spring; and when a chain is
employed, the same result is obtained by virtue of an adjustable balance weight, or
like contrivance, conveniently adapted to said flap or valve."
As a further modification to the foregoing arrangements for actuating the valve A
I may employ an automatic device shown Figure 6. It consists of a boxing or
casing I, provided at the junction of the yard pipes with the closet pan-in which
is pivoted a shallow tray or "tipper" J, of any desired shape or design, arranged in
a position beneath the valve, so that on the "tipper" being filled from the overflow,
.it upsets; whereupon the arm d coming into contact with the extended flange e of the
valve, causes the latter to open and the pent up supply of water contained in the pipes
to escape; the continued rush of water keeping the valve open till all is gone when it
automatically resumes its normal position.
"Having, now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The apparatus for flushing water closets substantially as herein described.
2nd. In the apparatus herein described for flushing water closets the employment
of a hinged flap or valve A, or sliding valve G having an opening a, substantially
as and for the purpose specified.
