I, ALBERT ROBERTS 62 Albert Terrace Road, Sheffield in the County of York
Sanitary Engineer do hereby declare the nature of this invention to be as follows :-
--
My invention relates to improvements in apparatus for preventing the flow of
Sludge or other refuse through the gulleys into the sewers at the same time
maintaining the perfect ventilation of the gulley. In carrying out my invention I
construct a pan of rectangular or other required form, the sides of which I perforate
to allow the water to drain into the sewer, on the bottom of the pan I affix two
handles so placed and constructed that they serve as feet on which the pan is sup-
ported when placed in the gulley; the handles are also most convenient for inverting
and emptying the pan of its contents. For the purpose of lifting out and carrying
the pan I provide a pair of handles which project above the top edge of the pan and
also form carriers for the hopper hereafter described which they support at the
required height from the pan, thus securing ample space for the passage of air.
The Hopper before mentioned I construct of strong sheet iron or steel, made to fit
close to the underside of the gulley frame, sloping from all sides and sufficiently
wide at the top to well overhang the pan. One side of this hopper I continue down-
wards in the form of a diaphragm arranged at such an angle and reaching into the
pan, in such a manner as to convey the liquid entering the gulley grate to the side
of the pan, thus preventing its falling heavily and disturbing the sludge already
collected, one end of the hopper may be made to slide along the sides to reduce
its length and facilitate its introduction below the flange or grate seat in the gulley.

Improved Sludge-pan Applicable to Street Gulleys and other
like Gulleys.
I, ALBERT ROBERTS 62, Albert Terrace Road, Sheffield in the County of York,
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:-
My Invention relates to certain improvements in apparatus for preventing the
passage of sludge and other refuse through the street gulleys into the sewers, and at
the same time maintaining perfect ventilation, and preventing the unsealing of the
gulley Trap when the sludge pan is being withdrawn.
My invention is clearly illustrated in the accompanying sheet of drawings, in
which Fig. 1, represents a side elevation of my improved sludge pan in a street
gulley.
Fig. 2, represents an end elevation of same, the gulley in both figures being shown
in section.
In carrying out my invention as shown in the drawings I construct a sludge pan A
preferably of rectangular form, but I do not bind myself to any particular form of
pan, as the shape may be varied to suit the construction of the gulley and I prefer to
perforate the sides of the pan near the top with holes B to allow the water to
drain or pass off into the sewer C.
Under the bottom of the sludge pan A I fix two feet or supports D of such a height
that the bottom of the sludge pan is supported above the seal of the sewer trap E
these supports are constructed to act as handles by which the pan may be inverted
and emptied of its contents in a convenient and easy manner.
For the purpose of raising the sludge pan out of the gulley (for the purpose of
emptying) a pair of handles F are provided which stand conveniently above the top
edge of the pan for the purpose specified; these handles may be used for the double
purpose of lifting the pan and also to support a Hopper or water shed G at such a
height as to allow sufficient space for the passage of air for ventilation of the gulley,
and sufficiently near to the underside of the grate H and grate frame I to catch all
the surface water as it passes through the openings in the grate, or between the grate
and its frame I.
The Hopper may however if preferred be cast upon or secured to the underside of
the grate Hitself. One of the sides of the Hopper (which may be satisfactorily made
of sheet iron) is continued downwards, forming a shoot J, reaching across the mouth
of the pan in such a manner as to convey water falling upon it from the grate, to the
side of the pan, and prevent it disturbing the sediment of sludge already collected
in the pan
One end of the hopper may be made to slide upon the other part to
allow it to be shortened so as to facilitate its introduction into, and removal from the
space below the contracted opening caused by the flange or seat of the grate, seen
at I.

page_text: To prevent the sludge being retarded in leaving the pan by reason of its adhersive
nature, causing a partial vacuum, I fix a flap valve K inside and at the bottom of the
pan, opening inwards to a sufficient distance for the required purpose as shown in
Fig. 2, thus when the pan is tilted up to empty it, the tendency of the flap is to open
and admit air which at once releases the sludge.
Also when the pan is put down into the gulley with some depth of water in it, the
valvo will admit the water into the pan and prevent the passage of sludge into the
gulley.
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 1
claim is :-
1-The improved sludge pan, and hopper constructed substantially as herein before
described and shown for the purpose specified.
2-A sludge pan, constructed with the combined supports and handles D for the
purpose hereinbefore specified, and substantially as described and shown.
3 The combination of a sludge pan A top handles F, bottom handles or sup-
ports D, and flap valve K all arranged substantially as described and shown for the
purpose specified.
