PROVISIONAL SPECIFICATION.
Improvements in Surface Water Gullies.
We, THE PATENT GULLY COMPANY, LIMITED, of Saint Peter's Church
Walk, and LORENZO WILLIAM CROSTA, of 6, Park Avenue, West Bridgford,
Engineer, both in Nottingham, do hereby declare the nature of this invention to be
as follows:
This invention relates to improvements in surface water gullies of the kind
described in the Specification of Letters Patent No. 3878, dated 22nd February
1893, granted to the said L. W. Crosta, and which gullies are provided with a bell
or bonnet formed on the underside of the grating, or made separate therefrom.
Now, the object of the present improvements is to make provision for surface
water being carried away after a sudden thaw, in the event of the water at the
bottom of the bell or bonnet having become frozen; or in case a block or stoppage
has been caused by any other means in the said bell or bonnet.
For this purpose, and according to a suitable arrangement, we provide the bell
or bonnet, above the ordinary water level, with a self-acting valve so disposed that,
should water accumulate in the said bell or bonnet, the pressure of such water will
cause the valve to open and allow this water to pass away to the drains, thus
obviating any stoppage or block in the gully.
In some cases we may dispense with the valve, and in place thereof, the bell or
bonnet may be provided with one or more openings or perforations arranged above
the ordinary water level.

1mprovements in Surface Water Gullies.
We, THE PATENT GULLY COMPANY, LIMITED, of Saint Peter's Church
Walk, and LORENZO WILLIAM CROSTA, of 6, Park Avenue, West Bridgford,
Engineer, both in Nottingham, 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, reference being had to the
accompanying drawings and to the letters and figures marked thereon, that is
to say :-
This invention relates to improvements in surface water gullies of the kind
described in the Specification of Letters Patent No. 3878, dated 22nd February
1893, granted to the said L. W. Crosta, and which gullies are provided with a bell
or bonnet formed on the under side of the grating, or made separate therefrom.
Now the object of the present improvements is to make provision for surface
water being carried away after a sudden thaw, in the event of the water at the
bottom of the bell or bonnet having become frozen; or in case a block or stoppage
has been caused by any other means in the said bell or bonnet.

page_text: And in order that the said invention may be readily understood, we will proceed
to describe the same by aid of the accompanying drawings, in which:
Fig. 1 is a vertical longitudinal section of a gully having a bell or bonnet
constructed according to the present invention;
Fig. 2 is a transverse section on the line x, x, of Fig. 1; and
Fig. 3 is a detail view showing, also in transverse section, a modified arrangement
of bell or bonnet which we may sometimes employ.
a is the gully, a¹ the vertical partition dividing it into two compartments b and c,
the bend or dip, and d the bell or bonnet, all these parts being similar to those
described in the Specification of the aforesaid Letters Patent.
In the arrangement shown in Figs. 1 and 2, and according to the present
improvements, this bell or bonnet is formed with an opening or overflow outlet d²,
situated above the ordinary water level. In connection with this opening a self-
acting valve d², is provided, which is hinged above the upper edge of the said
opening at d³, and normally hangs down over the mouth thereof after the manner
of a flap valve. By means of this arrangement, should water accumulate in the
bell or bonnet, from any of the causes above mentioned, the pressure of such water
will effect the opening of the valve and thereby enable the water to pass away to
the drains, thus obviating any stoppage or block in the gully.
In the modified arrangement illustrated in Fig. 3, the valve is dispensed with,
and in place of a single large opening, as at d', the bell or bonnet is provided with
a number of smaller openings or perforations d*, arranged around the walls of the
same, or otherwise disposed as may be desired, above the water level.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
-
1. In a surface water gully of the kind hereinbefore referred to, providing the
bell or bonnet with means for permitting the escape therefrom of surplus water in
the event of its ordinary outlet becoming blocked from any cause, substantially as
set forth.
2. In a surface water gully of the kind hereinbefore referred to, the bell or
bonnet d having a self-acting valve (such as d²) arranged above the ordinary water
level, substantially as described and shown with reference to Figs. 1 and 2, and for
the purpose set forth.
3. In a surface water gully of the kind herein before referred to, the bell or
bonnet d having openings or perforations (such as d) arranged above the water
level, substantially as and for the purpose described, and as shown in Fig. 3 of the
drawings.
