PROVISIONAL SPECIFICATION.
Improvements in Stall Urinals or Urinal Ranges.
I, THOMAS WILLIAM TWYFORD, of Cliffe Vale Pottery; Hanley, in the
County of Stafford, Manufacturing Sanitary Potter, do hereby declare the nature
of this invention to be as follows:-
This invention relates primarily to detail improvements in stall urinals or urinal
ranges, and has for one of its objects, a more efficient arrangement of the flushing
means, for another object, the hooding-over or partial hooding over of the flushing,
drainage or collecting channel, and for a further object, the making of the said
flushing or drainage channels self-cleansing.
My invention consists, in the one part, in providing such stalls with side and
bottom flushing rims; in the second part, in hiding or setting back the collecting
channel located at the bottom of the stall, under the foot steps, nearly out of sight,
and in the third part, in making the flushing or drainage channel self-choking and
consequently self-cleansing.
In carrying out one form of my improvements in connection with a range of stall
urinals, I arrange a series of inside concaved and upright blocks or slabs side by
side, and provide each of the same, at the top, with a hollow coping, wherethrough
the supply of flushing water is carried and from whence it is conducted down side
hollow flushing rims, pierced with holes and formed in the earthenware or fireclay
of facing uprights, which are recessed at back and are adapted to bond together
the stalls and hide or break the joint between their adjacent edges.
As a further improvement, I may provide the said facing uprights with forwardly
projecting partition slabs, for more effectually dividing off the stalls and hiding the
users from one another.
The bottom of each semi-circular or niche-shaped compartment inclines and
drains from back to front into a partially hooded over drainage or flushing channel,
so constructed that water passing from one stall to another is partially choked in
a small connecting pipe or opening, whilst the running water is unseen or screened
from view.
The hidden channel may, if desired, have in connection with it a trap which is
choked and self-cleansed by syphonic action.
In carrying out my invention in connection with a bottom flushing arrangement,
which may either be used independently or in conjunction with the side Hushing
already described, I employ like stalls as before, but I dispense with the hidden
drainage channel and provide the edge of the foot step with a flushing rim, from
which the bottom of the stall inclines downwardly into a semi-circular collecting
channel, which is in communication with the whole of the stalls of the range, and
which carries the water into the drain.
My improvements are applicable to single stall urinals, equally as well as to
ranges thereof, such as hereinbefore described.
Dated this 11th day of March 1895.

I, THOMAS WILLIAM TWYFORD of Cliffe Vale Pottery, Hanley, in the
County of Stafford, Manufacturing Sanitary Potter, 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 primarily to improvements in stall urinals or urinal
ranges and has for its objects principally, the concealing from view of the water
contained within and flowing through the drainage channels, and the more efficient
flushing of urinals generally.
Thus, my invention consists in the one part, in partly covering up or hooding
over the drainage channel formed in the floor of the stall, and in another part, in
providing urinal stalls with side and bottom flushing rims.
In carrying out one form of my improvements in connection with a range of stall
urinals, I arrange a series of inside concaved and upright blocks or slabs side by
side, and provide each of the same, at the top, with a hollow coping, wherethrough
the supply of flushing water is carried and from whence it is conducted down side
hollow flushing rims, the latter pierced with holes and formed in the earthenware
or fireclay of the facing uprights, which are recessed at back and are adapted
to bond together the stalls and hide or break the joint between their adjacent
edges..
The passages of the side flushing edges may lead to flushing rim passages at the
foot, forming boundary edges to the treads and with the jet holes directed down-
wards, whilst the jet holes of the side flushing rims are directed inwards towards
the back of the stall.
As a further improvement, I may provide the facing uprights with forwardly
projecting partition slabs, for more effectually dividing off the stalls and hiding the
users from one another.
According to another form of my improvements, the bottom of each semi-circular
or niche-shaped compartment inclines and drains from back to front into a partially
hooded over or hidden drainage in channel.
In carrying out my invention in connection with a top flushing arrangement,
which may either be used independently or in conjunction with the side flushing
already described, I employ like stalls as before, but with a sparge pipe running
along the hollow coping.
Figure 1 of the accompanying drawing represents in front elevation, a range of
urinal stalls provided with improvements made according to one form of my
invention.
Figure 2 is a vertical section of one of the stalls upon the dotted line
Figure 1.
Figure 3 represents a horizontal section of Figure 1, upon the dotted line x', and
with the bottom or floor flushing channel broken into.
a represents a range of urinal stalls, made up of a series of inside concaved
upright blocks or slabs a¹, set side by side and each provided with a hollow
coping, having a water service passage or channel b', (supplied by a metallic
connection e) through it, leading to bollow and perforated rims c¹, conducted
down the front facings c, which like the blocks a, rest upon base slabs d,
which have, at their inner boundary edge, flushing rims d, with jet holes made
through the walls and directed towards the bottom of the drainage d', which

page_text: inclines from the treads at d³, to the common drainage channel d' running at the
back of the base slab.
The jet holes in the front facing uprights are directed inwards and presented to
the side walls of the urinal adjacent to the said facings, so that the jets of water,
after striking the said side walls, flow towards the middle of the concave of the
inside back of the stall whereby the whole surface of the said back is flushed from
top to bottom, whilst the jet holes in the bottom flushing passage are directed in
the same general plane as the drainage incline so as to effectually flush the whole
surface of the same from the flushing rim to the drainage channel.
If necessary the stalls may be flushed at the top as well as at the sides and
bottom by providing the water service passages with jet holes directed through.

provided with a partly hidden or hooded over drainage channel.
Figure 5 is a vertical section upon the dotted lines ³, Figure 4.
Figure 6 is a horizontal section of Figure 4 upon the dotted line ³.
Figure 7 represents a perspective view of the said range of stalls and Figure 8
is a section of the base, showing more clearly the partly hidden drainage
channel.
Figure 9 represents a modified form of facing upright having an outwardly
projecting partition slab for better screening the user of urinal from view.
In Figures 4 to 8, a is a range of urinal stalls, made of series of upright blocks a',
connected together by facing uprights and provided with top copings, the whole
being supported upon base slabs d, each having formed within it at the front or
tread side, a partly hidden or hooded-over channel d', the hooding consisting of an
overhanging eave part a, terminating a drainage slope d³, sunken or formed within
the middle of the treads d', and with the said partly hidden drainage channel
terminating a second drainage slope d³, directed from the back to the front of the
floor of the stall. The treads have tiles f, inlayed within them or set within.
recesses d³, let within the base slabs d.
In Figure 9, the facing uprights c, connecting together the stalls a', are provided
with outstanding partition slabs c, for more effectually dividing off the stalls and
screening the user from view.
The stalls and their cognate parts may be made of earthenware, fire-clay, iron or
other suitable material.
It is understood that instead of access to the drainage channel, being gained by
a continuous entrance, water may drain thereinto through a series of holes or
openings.
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
First. In single or range urinals, providing or forming the structures, or the
component parts of the same, with integral flushing rims, substantially as and for
the purpose described and set forth.
Secondly. In urinals, cleansing the drainage slopes and channels of the same by
a bottom flush, or by a flush directed from the base, substantially as described and
set forth.
Thirdly. In the drainage channels of urinals, hooding over or partly hiding the
same by an eaving slab or overhanging part, substantially as and for the purpose
described and set forth.
Fourthly. In the drainage slabs of urinals, directing the drainage slope from
back to front and providing at the foot of the said slope a partly hidden drainage
channel, substantially as described and set forth in Figures 4 to 8.
Fifthly. In urinals or urinal ranges, the general construction, arrangement and
combination of the parts, substantially as described and set forth in Figures 1 to 3..
