I, CHARLES GLOSSOP, of 121, Hadfield Street, Walkley, Sheffield in the County
of York, Building Material Merchant, do hereby declare, the nature of my invention
for A NEW OR IMPROVED DISH OR BASIN FOR DRAIN-GULLIES to be as follows:-
This invention has for object to provide a new or improved dish or basin for
fixing on the top of drain-gullies to receive the water flowing through waste pipes
from slopstones, baths, etc, and which may be more easily cleaned and is not
liable to overflow, and will' at the same time secure a rapid outflow or discharge of
the water received by it along with efficient ventilation and convenience of shape.
Water flowing from kitchen slopstone pipes, baths, etc falls in general into a
shallow brick, clay, or earthenware grate or perforated dish above ground or nearly
level with the surface of the ground, the said dish fitting on the top of the gully
down which the water is led into the drains-The shallowness or want of capacity
of this perforated dish, when there is a strong flush of water from the waste
pipes, causes the water to overflow on to the pavement as it cannot get down into
the gully quick enough, and as the trough of the dish is too small to hold much
water at a time. Also in the smaller sized gullies when fitted with loose grate the
inner flange or ledge required to rest the grate on so narrows the opening that it is
difficult, after removing the grate, to put one's hand into the gulley to clear out
accumulations of dirt or obstructions.
If the receiving dish be made as a grid it presents the objections of either
standing above the surface of the ground which causes a stumbling block to foot-
passengers, or, if it be placed level with the ground it necessitates a disturbance of
pavement when its removal is desired, for cleaning out the gulley, or other
purposes Further the old dish, when standing over shallow gullies renders the
connection of the drain pipe with the gulley outlet liable to damage or breakage
by causing it to be placed too near the surface of the ground.
In my new or improved dish or bason for drain-gullies the above-mentioned
objections are avoided as follows:-
For a shallow dish, with only one grate, on the top of which the water from the
waste pipe falls, I substitute a comparatively deep bason, to fit on the top of the
Price Q17

page_text: gulley say six inches deep, or any other convenient depth, and this basin has two
grates, one for filtering, and the other for ventilating purposes. The grate for
filtering is at the bottom of the bason, and may form part, or whole of the bottom,
of the basin and be of any suitable, or convenient shape, size, or material-This
filtering grate may be lifted out when necessary in order to obtain access to the
gulley.
The ventilating grate may be flat or slightly hollow or any other suitable or
convenient shape and is placed at the top of the bason and provided with sufficient
apertures to facilitate the escape of bad air and gases.
The ventilating grate may, if necessary or convenient, be made to open and
close without removal by means of a hinge or other suitable device which will
cause it to open and close like say the lid of a box.
The ventilating grate and top of the basin are level with the surface of the
ground.
The outlet end of the waste pipe would fit in a groove made in the top of the
basin's rim and the ventilating grate will fit over.
The water flowing down the pipe into the basin has, the basin being deep, a
capacious receptacle to fall into, which gives it time to run away down the
filtering grate into the gulley without overflowing at the top.
The shape of the basin may be either a tapered round with square top or
a square top tapered down in the body or any suitable configuration.
The bottom of the basin may fit on the top of the gulley in any usual or suitable
manner which may render it possible to turn the bason in any necessary direction-
The depth of the dish causes the connection and flange of the gully outlet to be
placed sufficiently deep underground to preserve it from damage.
It will thus be seen that this application is for a patent filtering and ventilating
bason for the top of drain gullies and with two grates and deeper than ordinary (a
dish not a basin having been previously used) in order to prevent the overflow of
water on the surface of the ground and other objections as explained above.

page_text: I, CHARLES GLOSSOP, of 121 Hadfield Street, Walkley, Sheffield, in the County
of York, Builder, do hereby declare the nature of my invention for "A NEW OR
IMPROVED DISH OR BASIN FOR DRAIN GULLIES and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
This specification bears reference to my provisional specification No. 1218 dated
January 27th. 1886, which is hereby confirmed & further elucidated.
A reference to the annexed drawings will also materially assist the description
and ascertainment of the said invention. It will be seen that:-Fig. 1 represents
the outside view of the complete dish or basin and bell-trap combined. Fig. 2
represents the section & shows the inside view of the dish or basin-Fig. 3 repre-
sents the top of the dish or basin with the ventilating grate in its position Fig. 4
represents a sectional view of the top of the bell-trap forming the filtering grate
at or near the bottom of the dish or basin. Of the letters on drawings the letter A
represents the cylinder or basin proper: the letters C. C. represent the concentric
circles forming the ventilating grate B, the spaces between being the apertures:
the letter D represents the fast rim on which the ventilating grate rests: the
letter E represents the connecting bar which joins the 2 sides of the rim D under-
neath the ventilating grate the letter F represents the channel in the top of the
basin in which the outlet end of the waste pipe is laid & conducted under the
ventilating grate the letter K represents the top part of a bell-trap: the letter J
represents the other part of a bell-trap: the letter L represents the filtering holes
in the top part of the bell-trap K: the letter I represents the projecting spoke of
the ventilating grate the letter M represents the pin which goes through the
projecting spoke I: the letter H represents the split tongue of the rim D: the
letter G represents the catch or fastener of the ventilating grate.
For the usual shallow dish with its invariably one grate used to fit on the top
of drain-gullies to receive water flowing from waste-pipes, I substitute a capacious
bason or funnel with two grates one for filtering, and one for ventilation. The
shape of the basin may be either a tapered round with a square flanged top or a
square flanged top tapered down in the body or other suitable shape but by
preference the same shape as shown in the drawing. The bottom of the basin
may fit on the top of the drain gully in any usual or suitable manner which may
render it possible to turn the basin in any required direction. The basin A itself
may be made of baked clay or earthenware or other material by means of moulds
or other suitable processes of manufacture-Through the bottom of the basin or
funnel there is a hole, or rather there is no bottom to the basin until the filtering
grate is placed there; and the basin itself without the grates looks like a short
piece of wide piping flanged at one end.
The filtering grate Fig. 4 on which the waste water falls is placed inside the
basin in or over the hole at the bottom of the basin & may form part or whole of

page_text: the bottom of the basin or may be placed in the top of the drain-gully & may be
made of any suitable size, shape, or material; or to better prevent smells from
arising, may consist of an ordinary metal bell-trap placed there as shown in
drawings. When necessary the filtering grate may be lifted out by hand in order
to obtain access to the gully.
The ventilating grate B is placed, on, or near the top of the basin A and is
provided with sufficient apertures to facilitate the escape of bad air and gases-
This grate may be made of iron or other suitable material and may be concave,
convex or flat.
.
The ventilating grate may be made like any ordinary grate or may consist of
three or several concentric rings of metal united by metal spokes from the inner-
most to the outermost ring, and one of which spokes projects beyond the outer-
most ring. In the said projection there is a hole for a round pin to go through-
In the square top of the basin, round the hole forming the mouth of the basin, is
an inner flange or a ledge say % of an inch or other suitable short distance from
the top of the basins rim or flange. On this ledge an incomplete metal rim D
rests and is cemented, being incomplete against the channel F. The said rim is
made to project in the form of a peg-shaped or split tongue H into a recess or
hollow left in the manufacturing in one of the corners of the top of the basin-
Through the two sides of the split tongue H a metal pin M passes and this pin is
made to pass through the hole of the above described projecting spoke I of the
ventilating grate which can be opened and shut on it like on a hinge.
A short bar of metal E connects the two sides of the metal rim D across a
narrow part of the cavity of the basin and forms a small arc of a circle at the side
of the circle opposite or nearly opposite to the split tongue of the rim. A metal
pin G is put through one of the concentric circles C or through one of the spokes
of the ventilating grate against where the latter falls over the said connecting
bar E. Attached to the underneath end of the pin is a metal tongue, or latch, and
on the top of the pin is a small tight fitting nut By turning this with a small
spanner the tongue or latch catches underneath the connecting bar E and makes
it impossible or difficult for the ventilating grate to be opened without the aid of a
spanner. This device is an important detail of the invention as it prevents
children from playing and tampering with the grate.
The ventilating grate and the top of the bason may be placed level or nearly
level with the surface of the ground. The outlet end of the waste pipe fits in the
channel F (which may be made in the manufacturing in the top of the bason's
rim), or it may be carried through a hole at the side of the bason, but preferably
as shown in the drawings; and the waste water is thereby conducted into the
bason underneath the ventilating grate and falls on to the filtering grate at the
bottom.
The bason or funnel being deep, the water which flows down the waste pipe
into it has a capacious receptacle to fall into and one which gives it time to run
away down the filtering grate into the drain gully without overflowing.
The said filtering grate stops the passage of gross sediment into the drain gully.
The depth of the basin has the further advantage of rendering the employment of
a shallow gully possible: one which can be fixed deeper from the surface of the
ground and is consequently less liable to breakage or injury from pressure or other
causes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st. A patent for a bason or funnel to fix on the top of drain gullies and in
which the outlet end of a waste pipe is brought beneath or at a lower level than
the top grate;

page_text: 3rd and made so that the outlet end of the waste pipe shall convey the water
into the bason between the two grates or underneath a top grate ;
4th and the use of which bason will trap or dissipate the smells arising from
drain gullies;
5th and with the advantage of the top grate being moveable for opening and
closing like the lid of a box and fastenable by a simple device of latching or
locking.
6th. The central idea of the invention being the substitution of a bason or
funnel for the usual shallow single grate on the top of which up to the present the
water from waste pipes has fallen.
