Improvements in Valve Closets.
I, JOHN REID, of 114 High Street, Ayr, Brass Founder, do hereby declare the
nature of this invention to be as follows:-
This invention relates to valve closets and it has for its object to improve their
construction.
Heretofore, with this class of closet, the "Bramah" valve has been fitted in an
empty valve box situated above the trap. As a consequence of this arrangement
whenever the valve was opened to allow the contents of the basin to escape any
foul air in said box escaped into the room. Under my invention this objectionable
feature is obviated by so constructing the closet that the valve always works in
water. The usual valve box is also dispensed with so that no foul air can
accumulate below the basin.
In carrying out my invention the trap pipe is, preferably, made of cast iron and
enamelled or coated on the inside and the outlet branch or part is longer and higher
than the inlet branch or part which latter is or may be made of an oblong or box
shape with a flange round the bottom for the purpose of securing it in position.
Fitted on this inlet part or box is a cover having a central opening and a valve seat
is fitted in the opening.
A "Bramah valve which is fitted on or to a spindle at the back of the box, can
be closed tight against the valve seat. The spindle of the valve, which has a
slotted lever or arm on its outer end which projects through the box, is operated by
means of a weighted lever which latter is or may be fulcrumed at the front of the
box. This weighted lever, which is connected to and operated from the usual pull
handle, has a pin on it which passes through and works in the slot of the slotted
lever.
The cup in which the pull handle rests is or inay be supported on a stay fitted to
the lid or cover of the box.
The valve seat or the box has a cupped recess on its upper side into which the
outlet or discharge branch of the basin is secured. The top of this recess is,
preferably, just on the same level as the bottom of the outlet orifice of the trap
pipe, so that, in reality, the box and cupped recess form part of the trap and are
always filled with water.
An overflow pipe connection, preferably made without the usual syphon bend,
leads from the basin to the side of the box.
The slotted arm or lever of the spindle is cushioned against a rubber, leather, or
other soft cushion fitted on the lid of the box.
The spindle may have a rubber or leather packing round it.
The basin is, preferably, made cylindrical or nearly cylindrical at its upper part
and tapered or conical at its lower part. A flushing rim or pipe, made in one with
the body of the basin, extends right round its upper edge and the outlet orifices in
said rim are tapered slightly so as to insure that the water jets spread themselves
out to an extent sufficient to secure a perfect flush. The overflow branch or union
is flushed by means of jets of water which issue from a passage way in communication
with the flushing rim of the basin.
If desired a lever and spring may be used in lieu of the weighted lever.
In some cases the weighted lever may be made longer and be fulcrumed at or
about its centre. In these cases in order to open the valve the free end of the lever
would be pushed down by means of a rod or equivalent.

page_text: The basin and trap pipe with the valve connections may be enclosed in an
earthenware pedestal or cover; or, if desired, the basin may be made to fit or rest
on or in an enclosing pedestal.
With this construction of closet, as the valve box is part of the trap and is
situated at a lower level than the orifice of the outlet branch, it follows that it and
also the lower part of the basin are always filled with water. As a consequence of
this construction foul gas is prevented from passing up into the basin or collecting
in the valve box. As the valve works in water its rubber face is kept in a soft
condition and it therefore always closes tight against its seat. The conic shape of
the lower part of the basin ensures a thorough wash out of the soil..
The water in the box part of the trap enters into and seals up the overflow pipe
so that it need not be made with a trap as usual.
The trap pipe and box may be made of lead, brass or other suitable metal if so
desired instead of cast iron.

1, JOHN REID, of 114 High Street, Ayr, Brass Founder, 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 relates to valve closets and it has for its object to improve their
construction.
Heretofore, with this class of closet, the "Bramal" valve has been fitted in an
empty valve box situated above the trap. As a consequence of this arrangement
whenever the valve was opened to allow the contents of the basin to escape any foul
air in said box escaped into the room. Under my invention this objectionable
feature is obviated by so constructing the closet that the valve always works in
water. The usual valve box is also dispensed with so that no foul air can accumulate
below the basin.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon
Fig. 1 is a side elevation, Fig. 2 a vertical section and Fig. 3 a plan, (with the
basin removed) of the valve closet.
Fig. 24, 4, 5, 6 and 7 are detail views.
Fig. 8 shows the closet as, enclosed by a pedestal.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.
In carrying out my invention the trap pipe a is, preferably, made of cast iron
and enamelled or coated on the inside and the outlet branch or part a' is longer and
.higher than the inlet branch or part at which latter is, or may be, made of an
oblong or box shape with a flange round the bottom for the purpose of securing it
in position. Bolted, by bolts b', to the flange a³ of this inlet part or box is a cover b
having a central opening 64 which coincides with the outlet opening at the bottom
of the basin e.
A "Bramah" valve c, which is preferably made in one with a spindle d, is carried
in bearings d¹ passed through the cover band secured in position by external nuts d²
(see Figs. 4 and 5). The valve c has a rubber ring c¹ let in it which, when the
valve is closed, presses tightly against the under side of the cover b.
The spindle d, which has a slotted arm h fitted on its squared outer end, which
projects through the box, is operated by means of a weighted lever j which latter

page_text: may be fulcrummed a ' in a fork k bolted to a lug k² cast on the cover at the front
of the box. This weighted lever, which is connected by the rod / to and operated
by the usual pull handle has a pin or stud i secured to it which passes through
and works in the slot of the slotted lever. is a washer.
rests is supported on a stay m secured, as
The cup m' in which the pull handle
shown, to the lid or cover of the box.
The cover b has an upwardly projecting ring on it which forms a cupped recess.
into which the outlet or discharge branch of the basin e is placed and secured,
preferably by means of pinching screws 63. The annular space between the ring
and basin is filled in with red lead. The top of this recess is, preferably, as shown,
just on the same level as the bottom of the outlet orifice a' of the trap pipe, so that
in reality the box and cupped recess form part of the trap and are always filled
with water as shown at Fig. 2.
An overflow pipe connection o, preferably made without the usual syphon bend,
leads from the basin to the side of the box.
The slotted arm of the spindle d is cushioned against a rubber, leather, or other
soft cushion fitted on the cover of the box.
The outer end of the spindle d as shown at Figs. 4 and 5 passes through a stuffing
box formed by a semi-circular plate screwed to the side of the box a² and which
is recessed on its inner side for the reception of an india rubber or equivalent
packing ring g which is stretched on to the spindle. If the spindle is ginch the
ring is preferably a half inch one. n is a ventilating branch.
The basin e is, preferably, made cylindrical or nearly cylindrical at its upper part
and tapered or conical at its lower part. A flushing rim e' or pipe, made in one
with the body of the basin, extends right round its upper edge and the outlet
orifices in said rim are tapered slightly so as to insure that the water jets spread
themselves out to an extent sufficient to secure a perfect flush. The overflow
branch o or union is flushed by means of jets of water which issue from.a passage
way o in communication with the flushing rim e' of the basin (see part plan at
Fig. 2^).
If desired a lever and spring may be used in lieu of the weighted lever ).
In some cases the weighted lever may be made longer and be fulcrumed at or
about its centre. In these cases in order to open the valve the free end of the lever
would be pushed down by means of a rod or equivalent.
The basin and trap pipe with the valve connections may be enclosed in an
earthenware pedestal or cover as shown at Fig. 8; or, if desired, the basin may
be made to fit or rest on or in an enclosing pedestal.
With this construction of closet, as the valve box is part of the trap and is
situated at a lower level than the orifice of the outlet branch, it follows that it and
also the lower part of the basin are always filled with water. As a consequence of
this construction foul gas is prevented from passing up into the basin or collecting
in the valve box. As the valve c works in water its rubber ring c¹ is kept in a soft
condition and as a consequence, the valve always closes tight against its seat.
conic shape of the lower part of the basin ensures a thorough wash out of the soil.
The water in the box part of the trap enters into and seals up the overflow pipe
so that it need not be made with a trap as usual.
The
The trap pipe and box may be made of lead, brass or other suitable metal if so
desired instead of cast iron.
The construction of the closet may be modified or altered without departing from
the principle of the invention.
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
consider novel and desire to claim is:-
1. The general arrangement and combination of parts of the valve closet,
substantially as hereinbefore described and shown on the drawings annexed.
2. In a valve closet, the combination with the trap, of a valve fitted therein and

page_text: arranged to work in the water of the trap, substantially as and for the advantages
hereinbefore set forth.
3. In a valve closet, the combination with the trap, of a valve working in the
water of the trap and a stuffing box through which the valve spindle projects,
substantially as hereinbefore described with reference to the drawings annexed.
4. The combination of the trap a, valve c working in the water of the trap and the
basin e, substantially as hereinbefore described and shown on the drawings annexed.
