NOW KNOW YE, that I, the said William Frederick Padwick, do
hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, reference being had to the
accompanying Drawings, that is to say :-

page_text: My Invention consists in providing ordinary fire-grates with a grating
which fits into the angle formed by the back and bottom of the grate,
so that a good current of air being admitted into the back of the fuel
greater heat is obtained and an economy in fuel is effected. This
additional grating is preferably of the full width of the back of the grate,
and is, say, five or six inches in height; it rests at top against the back
of the grate, while its bottom, which rests upon the bottom of the grate,
is brought forward about three or four inches, more or less.
Figure 1 of the accompanying Drawings is a front view, and Figure 2
a side view of my grating; Figure 3 is a section representing it in
position in an ordinary fire-grate. As here shown it consists of a
grating a provided with cheeks b, b, and the angle formed at c by the
front and bottom is such as to cause the grating to have a suitable
inclination when placed in a grate, as seen in Figure 3.
The grating may be rounded at the sides, if desired, and it may either
be placed loosely in the grate or be fixed thereto by screws or otherwise.
In witness whereof, I, the said William Frederick Padwick, have
hereunto set my hand and seal, this Seventh day of July One
thousand eight hundred and seventy.
WILLIAM FREDERICK PADWICK. (L.S.)
