PROVISIONAL SPECIFICATION,
An Improved Automatic Waste Preventing Valve.
I, JOHN ANDERSON MCNAUGHTON Brassfounder and Mechanical Appliance Maker
55 Inglefield Street Glasgow, S.S. do hereby declare the nature of this invention to
be as follows:-
:-
The object of this invention is the production of Valves intended for application to
Water Closet Cisterns, or other vessels in order to secure the prevention of waste and
the discharge of a required or measured quantity of water or other liquid.
The valve consists of a seat having the two arms of its bridge so placed and
constructed as to stand vertically and that in such manner as to offer litile obstruc-
tion in and afford a maximum extent of waterway.
Through the central stud of bridge there is passed vertically a hollow spindle, to the
upper end of which is attached a weight retained in position by means of a nut
screwed to upper end of Spindle. Between the valve seat and the under surface of
this weight there is a flat washer of Indiarubber or other suitable material, in turn
screwed in its required position on Spindle by means of a nut on its under surface.
The valve is closed by the operation of weight rested on upper surface of washer
causing same to be brought in contact with the upper surface of seat.
The flat washer forms a characteristic feature of my invention. The ledge of said
washer projects beyond the outer diameter of seat to a degree sufficient to form a
vacuum when it is in contact with the hereinafter mentioned dome. Over the top of
and inclosing the weight, is the dome, having a central solid guide rod or spindle
working into the fail spindle of the valve. By means of the contact of the under
surface of the dome and the upper surface of the outer ledge of the above mentioned
washer there is effected the twofold purpose of the formation of a vacuum to ensure
the opening of the valve. And the effective affording of additional tightness to the
valve. The discharge of the required quantity of water or other liquid is regulated by
the Introduction through side of dome of a small screwed pin, which has on one side,
a groove, tapered in the direction of its length. According as this pin is screwed in
or out through the dome the quantity of discharge will be subject to regulation.
This screwed pin regulating the quantity of air admitied into the dome, is claimed as
a feature special to, and characteristic of my invention.
Valves made in accordance with the foregoing description are designed to be simple
in construction and consequently capable of being easily and cheaply repaired and free
from liability to go out of order in use.

55 Inglefield Street Glasgow 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 object of this Invention is the production of valves intended for application to
water closet cisterns or other vessels in order to secure the prevention of waste and
the discharge of a required or measured quantity of water or other liquid.
The valve consists of a seat having the two arms of its bridge so placed and con-
siructed as to stand vertically and that in such manner as to offer little obstruction in
and to afford a maximum extent of waterway.
Through the centre stud of Bridge there is passed vertically a solid Spindle B having
a flat disc cast on centre so as to form a seat for the hereinafter mentioned Indiarubber
Washer H.
On the centre of Spindle is screwed a weight. Between the valve seat and the under
surface of said weight there is a flat washer of Indiarubber held in its required position
by means of the weight. D which being screwed effects the twofold purpose of mut for
binding the washer and weight for tightening the Valve.
The valve is closed by the operation of the weight D rested on the upper surface of
the washer causing same to be brought in contact with the upper surface surface of
the seat. The ledge of the said washer projects beyond the outer diameter of valve
seat a degree sufficient to form a vacuum when it is in contact with the hereinafter
mentioned dome. Over the top of & enclosing the weight, is the Dome, which has a
hollow guide F passed through the top from the inside F-and held in a central
possition by means of the eye or ring piece of the valve-which is screwed on to the
upper end of said guide. The upper end of the aforementioned spindle works into
the Hollow guide for the purpose of keeping the Dome in a central position.
On the extreme upper end of spindle is screwed a small round nut K so that the
dome in working cannot be jerked out of position.
And to the extreme lower end of Spinille is attached a ring or pin A to keep it in
its required position while working.
By means of the contact of the under surface of the dome-and the upper surface
of the outer ledge of the above mentioned washer-there is effected the twofold
purpose of the formation of a vacuum to ensure the opening of the valve, and the
effective affording of additional tightness to the valve.
The discharge of the required quantity of water or other liquid-is regulated by the
turning of the eyepiece of the valve which has a ledge on its lower end sufficient to
admit of a hole J the thirtysecond part of an inch in diameter being drilled through it,
and likewise through the top of the dome. The hole through the ledge of the eyepiece
and the hole through the top of the dome E being in a line with one another.
According as the eyepiece is turned to right or left, the quantity of discharge will be

page_text: subject to regulation. The eyepiece of the valve thus being made to effect the three-
fold purpose of an eye for attaching the wire or chain of the valve too. A nut for
bending the guide to the dome, and a regulator for regulating the air admitted into
the dome.
The weight & dome are composed of lead hardened with antomony. With the
exception of the rubber washer all the other parts are composed of Brass. Valves
made in accordance with the foregoing description are designed to be simple in
construction & consequently capable of being made at a small price, and free from
libility to go out of order in use.

CLAIMS.
I claim the following as being special too and characteristic of my invention.
1 The manner in which the arms of the Bridge are made and placed in the seat.
2 The solid spindle and top guide.
The manner of imparting a double tightness to the valve, and that by one plain
Indiarubber washer. The inside weight making the washer bear directly on the upper
rounded surface of the seat then the dome which bears on the washer outside
the seat.
4 The manner of admitting air into the dome and that by the small counteracting
hole through the eyepiece and top of the dome.
