JAMES GEORGE STIDDER of 50 Southwark Bridge Road in the County of
Surrey Sanitary Engineer "IMPROVEMENTS IN APPARATUS FOR SUPPLYING,
FLUSHING, DISCHARGING AND TRAPPING ARRANGEMENTS FOR SANITARY AND
SEWERAGE PURPOSES WITH BOXES AND GRATINGS AND IN APPLIANCES CONNECTED

The object of my invention is to provide means and appliances in connection
with household sanitary apparatus for rendering the same clean sightly preventing
offensive effluvia and rendering the same accessible for cleansing and for removing
obstructions,
The means whereby I effect such Improvements will be readily understood by
the following description, reference being had to the accompanying drawings and
to the letters and figures marked thereon similar letters of reference indicating
corresponding parts in the several figures
Fig. 1 is a sectional elevation of a portion of a house fitted with my improved
appliances shewing also the arrangement of drain pipes gullies and traps in the
ground under and outside the house

the same enlarged a is a door in the front of the trap for the purpose of rendering
the trap accessible for removing obstructions This door is bolted to the front with
screw bolts or studs and nuts the joint being made air and water tight by any of the

purpose of better securing the same to the closet arm by a few turns of wire around
the horns and inlet arm of the closet basin The "weir" form of the pan at c is
for the purpose of constantly keeping a small quantity of water at the bottom as
shewn is the ventilating joint or aperture which is fitted to an ordinary
ventilating pipe

used as an intermittent flushing cistern self acting or as a manual flushing cistern
operating by the ring d and chain
Fig 5. is an enlarged view of a ball valve and Fig 6 is a plan of the same, the
branch pipe h¹ with dribble cock h² is for the purpose of slowly filling the cistern
and the float by its lever opens the valve when it rises and thereby brings the
syphon into action
Fig. 7 is a cross section of the junction and valve seat h³ shewing the mode of
making the connection of the two parts
Fig. 8 is a section of a Urinal with my improved accessible door a to trap fitted
thereto and the weir form of bottom holding a small quantity of flushing water as
shewn at c This Urinal is also shewn in position at 8 Fig. 1. with a cistern above
at 8° Fig. 1
Fig. 9 is a back view and Fig. 10 is a side view shewing my improved form of
closing Urinal This is enclosed in Cabinet work as seen at 9 Fig. 1 where it is
closed flush with the wall When it is opened for use as shewn in Figs 9 and 10
the operation of opening it turns on the water by means of the tap or valve i and
the cam 9a and the water continues running through the flushing pan until it is
again closed
Fig 11 is an elevation of a closet pan fitted with my improved accessible
doors a¹ a²; a¹ being for the purpose of getting to the trap and a² for getting to
the back flap from the overflow and safe waste k for clearing away obstructions.
The back flap k prevents cold air from entering into the closet basin or closet room
Fig. 12 is a sectional view of my improved syphon flushing cistern which is also
shewn in position at 12 Fig 1, a sink being also shewn draining into it This
cistern is shewn in Fig. 12 fitted for intermittent flushing The syphon g continues
out of action until the water rises high enough to charge the longer leg, when the
whole of the water passes through the syphon The ball air valve m is for the
purpose of confining the air in the pipes g and gl as the water rises When the
water has risen to the top of the syphon this air pipe is opened by the float m'
The ball air valve m is shewn enlarged in Fig 13
It is a diaphragm valve

the nozzle and so continues until the float again falls from the action of the
syphon-A dribble cock may be also attached at similar to that shewn in Figs 5
and 6 for filling the cistern in any given time

page_text: By placing the fulcrum of the lever as shewn in Fig 14ª this form of ball cock is
reversed in its action and is then suitable for all supply pipes, acting very quickly
and with great sensitiveness
The pipe & Fig. 1 is the soil pipe and the pipe 8' is the ventilating pipe leading
to the top of the house
Fig 15 is an enlarged section of 15 (Fig. 1) This is a trap with a special pro-
vision for removing dirt The grating has the usual hinge and underneath it is the
ordinary trap with water-seal-The cup is however fitted with an internal moveable
bucket t which catches heavy matter and which can be occasionally removed by
means of the handle t' and emptied of such matter
Figs 16 and 17 are respectively plan and section of my improved hinged plate
or cover for street supply stop-cocks The screw u holds down the cover until it is
required to be opened for examination or cleaning out the box The small lid, can
however be readily opened when necessary for applying the key to the spindle of
the stop-cock by means of a tool applied at the point u³ The weight u holds this
supplementary cover down and the formation of the whole cover keeps dirt from
entering the box
Figs 18 and 19 represent (in section) my improved man-hole doors for sewer
ways or man-holes v is a latch which is pressed forward by the weight and lever 23
acting on the centre The lip v presses back the latch when the grating is being
closed. The key is used to shoot back the latch from the outside when opening
the man-hole cover. 20 is a ratchet, 21 is a plate to stop the opening. 22 is a
hinged lug to take into the notches of 20 to hold the door open. This door is also
shewn in position at 18 Fig. 1.
There are two slanting bearing surfaces won the sides of the box which cause
the grating to slide to the right when it is closed as seen in Fig. 18. one end of the
grating rests on the provisions the other end resting on the slanting ledges w
When the door is raised the grating can be raised with it also and held to the
cover by the turnbuckle y When however it is desired to shut the grating only
leaving the door open the turnbuckle (or latch) is moved so that its head passes
between the bars the grating is forced away from the hinge and raised by the cam
and sloping supports w level with the ground line When both cover and grating
are raised the weight v² is also raised and pinned in position by means of the loose
pin in the holes 7 and 8 thereby holding back the bolt until it is necessary to
shut the grating or the grating and door
