COMPLETE SPECIFICATION.
A Self-fastening Coal or other Grid.
We, JOHN JAMES FRANCE of 36 Victoria Parade, Ashton on Ribble Bank Clerk,
and ROBERT CHEW of 3° North Road, Preston, 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 :-
This invention is an improved plate or cover to any opening or aperture usually
placed on the parapet in front of a house for the reception of coal or other material;
which securely locks itself when placed in its proper position and cannot be opened
except from the inside. It consists of two parts.
A is the plate or frame that is fixed in the opening.
B-is the plate or grid made either round, square, or any other shape.
The frame A has a bevelled edge on its outer diameter and next the flag, which fits
into a corresponding bevel in the opening of the flag. A rim or scat is cast on the
inner diameter of the ring or frame about half an inch from its upper edge upon which
the plate rests as a seat for said plate or grid B.
The plate or grid B has a Ĺ piece of metal fixed near its edge on the underside
and pointing outward. Opposite to this piece of metal and near the edge of the
plate B, also on the underside, is cast another projection to hold a paul or lever that
moves on a pin and its free end pointing upwards. This paul or lever only moves
outwards and upwards.
When the plate or grid B is placed obliquely on the frame A the ☐ piece of metal
goes under the inner rim of the frame A and as soon as the plate or grid B is down on
its seat the paul or lever moves outward and under the inner rim on A thus securely
fastening the plate or grid B.
Το open the grid lift the paul or lever into a vertical position when it will be clear
of the inner rim on A then the plate or grid B is free for removal.

page_text: 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 fixed finger or catch on the underside of the grid or plate B that engages
with the inner rim of the ring or frame A. and
2. The paul or catch that falls outward & under the inner rim or seat of the ring or
frame A by its gravity.
Dated this 2nd day of May 1800.
