Improvements in Valves for Closets.
1, FREDERICK BALL of 18 Bell Street, Henley-on-Thames, Oxfordshire, Sanitary
Engineer, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to the valves employed at the bottom of the closet basin and
the object sought to be attained is to ensure that the valve when opened shall be clear
of its seat so that paper may pass freely and not be so liable to be caught as with the
present form of valves. There are also other advantages such as preventing the
water from running along the spindle and so leaking outside, which may be secured
by my invention.
The basin is seated in a metal ring preferably of brass and at the underside of this
I form a depending ring or collar which may be rounded or tapered at its lower edge
to improve the bedding upon the valve. The spindle which carries the valve passes
behind this ring which protects it from water or paper and the spindle arm to which
the valve is fastened is cranked so that when it hangs down with the valve the latter
is removed well away from its seat even at that part nearest the spindle and is to some
extent protected by the before mentioned ring.
The valve itself consists of a metal disc or plate with a ring of india-rubber leather
or other suitable material which is held in place by a cover which may be secured to
the plate by a central screw which can readily be removed for changing the rubber
ring without removing the valve itself.
The ring which carries the basin is so constructed preferably by sloping the
flange that room is left in which the valve spindle can be placed at a considerably
higher level than is possible with the ordinary construction so as to be well behind the
depending collar which thus affords protection to it as already described.
The box upon which the ring sits may be also sloped to match the slope of the
ring and may be formed with a recess to accomodate the valve when off its seat
and preferably tapers towards its lower end.

COMPLETE SPECIFICATION.
Improvements in Valves for Closets.
I, FREDERICK BALL, of 18 Bell Street, Henley-on-Thames, Oxfordshire, Sanitary
Engineer, 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 the valves employed at the bottom of the closet basin and
the object sought to be attained is to ensure that the valve when opened shall be clear
of its seat so that paper may pass freely and not be so liable to be caught as with the
present form of valves. There are also other advantages such as preventing the water
from running along the spindle and so leaking outside, which may be secured by my
invention.
The basin is seated in a metal ring preferably of brass and at the under side of
this I form a depending ring or collar which may be rounded or tapered at its lower
edge to improve the bedding upon the valve. The spindle which carries the valve
passes behind this ring which protects it from water or paper and the spindle arm to

page_text: which the valve is fastened is cranked so that when it hangs down with the valve the
latter is removed well away from its seat even at that part nearest the spindle and is to
some extent protected by the before mentioned ring.
The valve itself consists of a metal disc or plate with a ring of india-rubber
leather or other suitable material which is held in place by a cover which may be
secured to the plate by a central screw which can readily be removed for changing the
rubber ring without removing the valve itself.
The ring which carries the basin is so constructed preferably by sloping the flange
that room is left in which the valve spindle can be placed at a considerably higher
level than is possible with the ordinary construction so as to be well behind the
depending collar which thus affords protection to it as already described.
The box upon which the ring sits may be also sloped to match the slope of the ring
and may be formed with a recess to accomodate the valve when off its seat and
preferably tapers towards its lower end.
In the accompanying drawings ;-—.
Fig. 1 is a side elevation and Fig. 2 a vertical section of a closet fitting constructed
according to this invention the full lines indicating the position of the movable parts
when the valve is closed and the dotted lines indicating their position when the
valve is open.
Like letters indicate like parts throughout the drawings.
A is the metal (preferably brass) ring in or upon which is seated the closet
basin which is not shown in the accompanying drawings. This ring A is preferably
formed in part with the inclined plate or Hange B on the underside of which is
the depending ring C whose lower edge is tapered or as shown in fig. 2 rounded so
as to form a good seating for the valve D which is preferably of india-rubber or
equivalent material and which is adapted to make a tight joint against the ring or
valve seat as shown in full lines in Fig. 2. E E¹ are the two plates between which
the india-rubber valve D is held and F is the screw by which the valve D
and plates E E¹ are secured to the cranked arm G and which screw may readily
be removed when it is necessary to change the valve D or for other purposes
without disturbing the valve operating mechanism. G₁ is a spindle with which the
arm G is either formed integrally or to which it is secured in any convenient
'manner. H is one of a pair of brackets in which the spindle G₁ is supported
at the underside of the plate or flange B and H¹ is a stuffing box which may be
provided to prevent the escape of water around the spindle G¹. The outwardly
projecting end of the spindle 'G' has fitted to it the usual curved and slotted arm J
with the slot J¹ of which engages an anti-friction roller carried by the lever K in the
manner ordinarily employed for operating the valve spindle G¹.
Lis the box upon which the ring A sits and to which it is secured by the flange B
the flange L of the said box being inclined to correspond with the inclination of the
first mentioned flange B these two flanges being fastened together by bolts and
nuts M or equivalent means.
By forming the flange B on an incline in the manner shown the spindle G¹ may be
located at a level higher than heretofore and at the outside of the ring C thus keeping
it clear of the water which passes through the said ring and thereby preventing any
water from running along the spindle to the outside of the box L as has hitherto been
found a cause of leakage while it also enables a longer crank to be given to the arm G
which admits of the valve when open being moved well away from the ring C to give
the paper a clear passage to the outlet L2 as will be best understood by referring to
the dotted position in which the valve is represented in figure 2.
Hitherto in arrangements of this description the valve has been pivotted close
against the edge of the valve seat and could therefore only be turned so as to hang
practically vertically downwards from the valve seat and thus tend to catch the paper,
whereas by the before described improvements the valve is moved bodily to one side
well out of the fairway through the apparatus.
Instead of arranging the flange B on an incline in the manner shown in the

page_text: accompanying drawings I may arrange it horizontally or in any other manner
convenient to the locating of the spindle G¹ at a higher level than and to one side of
the valve seat C.
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 ;-
1. In a closet-valve apparatus the combination with the ring or valve seat C of a
flange B so slanted or otherwise arranged as to allow of the valve spindle G¹ being
located outside the said ring and above the level of the valve seat substantially as
described and illustrated in the accompanying drawings.
2. A closet-valve apparatus so arranged that the downwardly opening valve when
opened is moved bodily to one side, well out of the fair-way through the apparatus
substantially as described and illustrated in the accompanying drawings.
3. In a closet-valve apparatus the employment of a cranked arm such as G whose
centre of motion Gt is outside and at a higher level than the valve seat whereby when
opened the said valve is carried bodily away from its seat substantially as described
and illustrated in the accompanying drawings.
