PROVISIONAL SPECIFICATION.
Improved Means or Method of Hinging Metal Grates to Stoneware
and other Gullies.
We, JAMES DUCKETT AND SON LIMITED and ALFRED DUCKETT, of Mitre
Sanitary Works, Burnley, in the County of Lancaster, Brick and Sanitary Pipe
Manufacturers, do hereby declare the nature of this invention to be as follows:-
This invention relates to stoneware and other gullies, and consists of an improved
means or method of hinging metal grates to the same. The arrangements which
have previously been adopted for this purpose have been in some way defective ;
in some instances, in consequence of the grate being loosely mounted in recesses
formed in the upper surface of the gully, and in other instances because the grate
was capable of being easily removed by children or dishonest persons.
In carrying out our invention, we provide the grate with the usual projecting
pins or lugs on each side. One of these is introduced into a recess or cavity formed
in the gully below the grating. On the far side of the gully is formed an extenuated
groove, slot, or cleft, in such a manner as to receive at an angle the other stud or
lug of the grate, which may then be pushed forward along the said slot or groove
to its seat, and in proper position.
The grate when in position can be opened and closed as if it turned upon an
ordinary hinge, and can be taken out and removed, if required. Moreover, it will
scarcely be possible for the grate to be removed without a knowledge of this novel:
method of hinging.
In order that our invention may be readily understood, we have hereunto
appended the accompanying sheet of drawings.
Fig. 1 is a vertical section, and Fig. 2 a plan of a gully and grate constructed in
accordance with our invention.
Referring to Fig. 1, A is the said slot groove or cleft formed in the gully B,.
covered by the grate C. As distinctly shewn in Fig. 2, the said gully is formed
with a hole or recess D, into which is inserted lug or stud E of grate C, the said
hole or recess being beneath the upper surface of gully. The grate is now held at
an angle as shewn in dotted lines in this figure, so as to permit of the stud F on the
other side of grate to be pushed forward along the said groove, slot or cleft A,
until it assumes its normal position at the extreme end of the slot or groove.
Fig. 3 is a sectional end view of the gully, and shews the relative positions the
grate assumes,―
1stly. In dotted lines with the grate at an angle, its lug E resting in the hole or
recess D, whilst the lug F is shewn as just entering the groove A.
2ndly. The final or normal position the grate assumes when the lug F is pushed
forward into its seat G.
Fig. 4 is a plan view of the gully shewing the ledges, upon which the grate
rests.

and other Gullies.
We, JAMES DUCKETT AND SON LIMITED, and ALFRED DUCKETT, of Mitre
Sanitary Works, Burnley in the County of Lancaster, Brick and Sanitary Pipe
Manufacturers, 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 :-
This invention relates to stoneware and other gullies, and consists of an improved
means or method of hinging metal grates to the same. The arrangements which
have previously been adopted for this purpose have been in some way defective;
in some instances, in consequence of the grate being loosely mounted in recesses
formed in the upper surface of the gully, and in other instances because the grate
was capable of being easily removed by children or dishonest persons.
In carrying out our invention, we provide the grate with the usual projecting
pins or lugs on each side. One of these is introduced into a recess or cavity
formed in the gully below the grating. On the far side of the gully is formed an
extenuated groove, slot, or cleft, in such a manner as to receive at an angle the
other stud or lug of the grate which may then be pushed forward along the said
slot or groove to its seat and in proper position.
The grate when in position can be opened and closed as if it turned upon an
ordinary hinge, aud can be taken out and removed, if required. Moreover, it will
scarcely be possible for the grate to be removed without a knowledge of this novel
method of hinging.
Our invention will be fully understood by reference to the drawings accompanying
our Provisional Specification.
Fig. 1 is
vertical section, and Fig. 2 a plan of a gully and grate constructed in
accordance with our invention.
Referring to Fig. 1, A is the said slot, groove or cleft, formed in the gully B,
covered by the grate C. As distinctly shewn in Fig. 2, the said gully is formed
with a hole or recess D, into which is inserted lug or stud K of grate C, the said
hole or recess being beneath the upper surface of the gully. The grate is now
held at an angle as shewn in dotted lines in this figure, so as to permit of the
stud F on the other side of the grate to be pushed forward along the said groove,
slot or cleft A, until it assumes its normal position at the extreme end of the groove
or slot.
Fig. 3 is a sectional end view of the gully and shews the relative positions the
grate assumes,―
1stly. In dotted lines with the grate at an angle its lug E resting in the hole or
recess D, whilst the lug F is shewn as just entering the groove A.
2ndly. The final or normal position the grate assumes when the lug F is pushed
forward into its seat G.
Fig. 4 is a plan view of the gully shewing the ledges, upon which the grate
rests.
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. The improved means or method of hinging metal grates to stoneware and
other gullies, substantially as described, and shewn in the drawings accompanying
our Provisional Specification.

page_text: 2. The slot, groove or cleft A and recess D, into which the lugs F and E are
inserted at an angle, and got into position substantially as described and illustrated
for the purpose set forth.
