PROVISIONAL SPECIFICATION.
An Improved Cover or Appliance for Providing Access to
Coal-cellars.
I, WILLIAM MOORE, of Mayfield Road, Eccles, in the County of Lancaster,
Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to an appliance for providing access to and a lid or cover
for closing the aperture on the ground level through which coal or the like is
conveyed into a coal cellar.
Hitherto access for this purpose has been usually had to coal cellars by means
of a circular hole or opening ent in a flag or stone which is covered by a circular iron
grid and it is to take the place of this ordinary form of coal grid that this invention
is designed.
It consists essentially of a metal framework, preferably rectangular, of any
desired size to fit over the roof or top of the cellar in which is pivoted or hinged
a plate capable of being raised and lowered, and when raised to afford access to
the cellar below stands in such a way as to form a back or shoot to direct the
coal downwards and also to protect the glass riser or plate which admits light, the
top of the plate being provided with a mat or scraper.
In carrying out the invention I construct a metal framework to be placed in the
roof of the cellar. This framework is preferably cast iron of any desired size and
can be supported by its ends resting on the walls. In the centre of this is formed
an aperture to provide access to the cellar. In this aperture I pivot or hinge a
plate which can be lifted or lowered to open or close theaperture and forms a
cover or lid therefor. It is so pivoted that when moved to open the aperture it
forms a back or shoot to direct the coal into the cellar and also to protect the
glass riser or sheet through which light is admitted. The framework may also
be provided with a groove for the glass riser to rest in.
On the top of the movable plate I cast two or more strips in which I insert
other strips of rubber, wood, metal, matting, or other suitable material to form a
scraper or mat and the remaining portion of the movable plate may be covered
with studs, ribs, or projections to prevent persons slipping thereon.
If desired two plates may be pivoted together or one pivoted inside the other so
that a greater or less aperture may be provided as required.

COMPLETE SPECIFICATION.
An Improved Cover or Appliance for Providing Access to
Coal-cellars.
I, WILLIAM MOORE, of Mayfield Road, Eccles, in the County of Lancaster,
Builder, 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 an appliance for providing access to and a lid or cover

page_text: for closing the aperture on the ground level through which coal or the like is
conveyed into a coal cellar.
Hitherto access for this purpose has been usually had to coal cellars by means
of a circular hole or opening cut in a flag or stone which is covered by a circular
iron grid and it is to take the place of this ordinary form of coal grid that this
invention is designed.
It consists essentially of a metal framework, preferably rectangular of any desired
size to fit over the roof or top of the cellar in which is pivoted or hinged a plate
capable of being raised and lowered and when raised to afford access to the cellar
below, stands in such a way as to form a back or shoot to direct the coal down-
wards and also to protect the glass riser or plate which admits light the top of
the plate being provided with a mat or scraper.
It will be fully described with reference to the accompanying drawings.

Fig. 2. Perspective view showing the cover raised.

Fig. 4. Transverse section of same.
A is a metal framework to be placed in the roof of the cellar it is preferably
made of cast iron of any desired size and is supported in position by its ends
resting upon the walls or on other suitable supports.
In the centre of the frame A is formed an aperture B through which access can
be obtained to the cellar below.
A plate C is hinged or pivoted in the aperture B forming a cover or lid therefor
which can be lifted or lowered on its pivot as shown to open or close it. The
plate C is so pivoted that when raised to open the aperture B it forms a back or shoot
to direct the coal into the cellar and also to protect the steps which will allow of a
glass riser or sheet D being placed therein with safety through which light is
admitted.
The framework A may if desired also be provided with a groove for the glass
riser D to rest in.
On the under side of plate C I pivot a catch E actuated either by a weight e or
by a spring which will cause it automatically to fasten the lid C when closed.
The top of the lid C 1 cast so as to form a scraper either with a number of
transverse strips c which in themselves form a scraper as shown or the strips may
be cast with grooves to receive strips of rubber wood, metal matting or other
suitable material to form a scraper or mat and the remaining portion of the
lid may be covered with studs ribs or projections to prevent persons slipping.
thereon.
The top of the framework A may be made of any suitable design and the space in
the lid C around the strips c may be recessed as shown and filled in with tiles.
If desired two lids or plates may be pivoted together or one may be pivoted
inside the other so that a greater or less aperture may be provided as required.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A cover or appliance for providing access to coal cellars through the top and
forming a protection for the steps and step riser when open, comprising a metal
framework to be set in the roof of the cellar and a lid or cover pivoted or hinged
thereto provided with a catch to secure it when closed the upper side of the
lid being formed as a scraper or mat substantially as and for the purpose
described.
