Improvements in and relating to Waste or Slop Water Closets.
I, ARNDALL HOCKING of 52, Belford Street, Burnley in the County of
Lancaster, Sanitary Engineer, do hereby declare the nature of this invention to
be as follows:-
The object of the present invention is to render it impossible for any article
to get lodged in the basin or trap of waste water closets. Hitherto, one of the
most serious objections to this class of closet has been that the trap, drain or
street sewer was often blocked up, owing to rubbish and articles such as old boots,
shoes, salmon-tins et cetera being thoughtlessly thrown into the closet, and the
present invention is uniquely designed as a positive preventive.
In carrying my invention into effect, at a suitable distance from the seat,
I insert or fix into the extension pipe or pedestal a longitudinal diaphragm or
partition. This diaphragm. may pass exactly up the middle of the pipe or
otherwise as desired, so as to form two divisions, one in front and another at the
back of the pipe, pan or pedestal.
The front division as will be hereinafter explained constitutes a receptacle or
pocket for any rubbish, which may be thrown into the closet. I form in the
front portion of the pipe or pedestal, a groove or recess, into which I fit a plate
of terra cotta, porcelain, glass, or the like to convey the urine from the front to
back of closet. This plate or shield may slope to any required degree of
inclination, and overhangs the receptacle or pocket. It is also made to lift out
to get at the rubbish deposited in the receptacle.
Immediately above the aforesaid diaphragm or partition. I mount on an axle a
movable flap of terra cotta or other suitable material formed to the required
curvature of the extension pipe or pedestal, and disposed so as to close the back
portion or division of the closet, when it is not in use. In this position it is
disposed preferably at an angle of about 45° in a reverse direction to the shield,
so that any articles, which may be thrown into the closet, will slide down the
surface of either the shield or the movable flap, and eventually fall into the
receptacle or pocket in front. This is formed with a perforated bottom to allow
any urine which may drip into the same, to run into the trap below.
The axle of the movable flap carries a pinion, which is acted upon by a toothed
quadrant or rack, worked by the depression of the closet seat in such manner
that when a person sits on the closet seat, the flap immediately turns on its axis,
and goes under the shield in front, leaving a clear opening at the back for the
passage of excreta and urine but when the person leaves the seat, a spiral or
other spring returns the flap to its normal position, closing the opening at the
back portion of the closet leading to the trap, and preventing the possibility of
any articles being thrown into the trap.
The closet seat is hinged at the back, and operates a vertical rod in front,
connected to the aforesaid toothed quadrant, the spiral spring being slipped on
the vertical rod, and rendered active by fixed bosses on the vertical rod and at
the side of the pipe or pedestal respectively, the rod sliding through the latter
boss. The side of the pipe or pedestal, where the toothed quadrant is pivotted
is preferably formed flat on its exterior surface to permit of ready fixing of the
mechanical parts.

page_text: The movable flap is provided with a rubber buffer or buffers to prevent
concussion or breakage.
Datel this 9th day of April 1896.

COMPLETE SPECIFICATION.
Improvements in and relating to Waste or Slop Water Closets.
I ARNDALL HOCKING of 52, Belford Street, Burnley, in the County of
Lancaster, 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 :-
The object of the present invention is to render it impossible for any article to
get lodged in the basin or trap. of waste water closets, or to pass down the shaft of
an earth closet. Hitherto, one of the most serious objections to these classes of
closets has been that the trap, drain, or street sewer was often blocked up, owing
to rubbish and articles such as old boots, shoes, salmon tins et cetera being
thoughtlessly thrown into the closet, and the present invention is uniquely designed
as a positive preventive.
In carrying my invention into effect, at a suitable distance from the seat,
I insert or fix into the extention pipe or pedestal a longitudinal diaphram or
partition. This diaphram may pass exactly up the middle of the pipe or otherwise
as desired, so as to form two divisions, one in front and another at the back or one
on each side of the pipe, pan or pedestal.
The front division, as will be hereinafter explained, constitutes a receptacle or
pocket for any rubbish, which may be thrown into the closet. I form in the front
or side portion of the pipe or pedestal, a groove or recess, into which I fit a plate
of terra cotta, porcelain, glass, or the like to convey the urine from the front to
back of closet. This plate or shield may slope to any required degree of
inclination, and overhangs the receptacle or pocket. It is also made to lift out to
get at the rubbish deposited in the receptacle.
Immediately above the aforesaid diaphram or partition, I mount on an axle a
movable flap of terra cotta or other suitable material formed to the required
curvature of the extention pipe or pedestal if same be curved, and disposed so as
to close the back portion or division of the closet, when it is not in use. In this
position it is disposed preferably at an angle of about 45° in a reverse direction to
the shield, so that any articles, which may be thrown into the closet, will slide down
the surface of either the shield or the movable flap, and eventually fall into the.
receptacle or pocket in front. This is formed with a perforated bottom to allow
any urine which may drip into the same, to run into the trap below.
The axle of the movable Hap carries a pinion, which is acted upon by a toothed
quadrant crank or rack, worked by the depression of the closet seat in such a
manner that when a person sits on the closet seat, the flap immediately turns on its
axis, and goes under the shield in front leaving a clear opening at the back for the
passage of excreta, but when the person leaves the seat, a spiral or other spring
returns the flap to its normal position, closing the opening at the back portion of
the closet leading to the trap, and preventing the possibility of any articles being
thrown into the trap.
The closet seat is hinged at the back, and operates a vertical rod in front,
connected to the aforesaid toothed quadrant, the spiral spring being slipped on the
vertical rod, and rendered active by fixed bosses on the vertical rod, and at the
side of the pipe or pedestal respectively, the rod sliding through the latter boss."

page_text: The side of the pipe or pedestal, where the toothed quadrant is pivotted is
preferably formed flat on its exterior surface to permit of ready fixing of the
mechanical parts.
The movable flap is provided with a rubber buffer or buffers to prevent concussion.
or breakage.
In the accompanying drawings, Fig. 1 is a side elevation of the pedestal of a.
waste or slop water closet or earth closet constructed in accordance with my
invention.
A is the pedestal; B the closet seat, which may be hinged thereto. At a
suitable distance from the closet seat, I fix into the extension pipe, pan or pedestal-
a diaphragm C or form the same therewith in one piece of earthenware. This
diaphragm divides the pedestal into two parts. The part A' answers as the closet
proper, whilst the part D serves as a pocket or receptacle for any rubbish (which
may be thrown down the closet) in the manner hereinafter explained.
The shaft of the movable flap E carries a toothed pinion F operated by toothed
quadrant or rack G mounted on the stud G on the exterior of the pedestal..
Movable flap E being in the interior is shewn in dotted lines in the figure, and
may be made in enamelled iron, glazed earthenware, porcelain or other suitable
noncorrosive material. In its normal position, it preferably rests at an angle of
about from 30° to 45° on the rubber or other buffer H, so as to completely
block up the opening of the closet to the trap, and cause any rubbish or articles,
which may be deposited in the closet by thoughtless or careless persons to be
diverted into the pocket or receptacle D by sliding down the surface of the flap..
It also, to some extent prevents the passage of foul or obnoxious gases.
When, however, a person sits on the seat, a small lip J thereon depresses the
rod K secured at its lower extremity to the toothed quadrant or rack G causing
the latter to actuate the toothed pinion F moving the flap from the position shewn
in the diagram to a vertical position; thus leaving a clear course for the passage.
of excreta.
The rod K slides in the fixed bosses or brackets L, and is depressed against the.
tension of a spiral or other spring M, which when a person leaves the seat, returns.
the flap to its normal position.
Fig. 2 is a sectional elevation of a modification of my invention. The toothed
quadrant and pinion are dispensed with, and in lieu thereof I employ a small lug-
or projection N secured to the movable flap, and to which the rod K is attached
direct. Movable flap is operated exactly in the manner previously described, and
when a person sits on the seat is brought by the depression of the rod K to a
vertical position as shewn by dotted lines, and the arrow.
In another modification of my invention, two pockets or receptacles for rubbish
may be employed, one on each side of the pedestal, the passage to the trap being
down the centre. Two movable flaps, when in their normal positions rest against
each other over the central opening of the closet pedestal like an inverted V, so.
as to block up the passage to the trap, and divert the rubbish into one or other of
the receptacles or pockets. They are operated exactly as described in the previous
arrangements, and assume a vertical position simultaneously when a person sits on.
the seat.
In all the said arrangements, the diaphragm C is perforated so as to provide a
vent for the urine which may flow down the flap or flaps E into the receptacle or
pocket. The bottom portion of the pocket is inclined, and formed with an.
opening at its extreme corner, so that paper which may find its way into the
pocket, becoming moistened by the urine will ultimately make its way into the-
trap.
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:-

page_text: blockage of slop or waste water closets or earth closets substantially as described
and illustrated in Fig. 1.
2. Movable flap E, pocket D, diaphragm C, and rod K operated by the
depression of the closet seat or otherwise, substantially as described and shewn for
the purpose specified.
3. The modification represented in Fig. 2, wherein the rod K is connected direct
to projection N secured to movable flap E, actuated substantially as and in the
manner set forth.
4. The modification consisting of two diaphragms, two movable flaps, and two
pockets or receptacles for rubbish, and actuated substantially as described.
