A RADIATING HEARTH PLATE
Year: 1852

page_text: LETTERS PATENT to George Hattersley, of Sheffield, in the County™
of York, Stove Grate Manufacturer, for the Invention of "A
RADIATING HEARTH PLATE."
Scaled the 28th April 1853, and dated the 28th October 1852.
PROVISIONAL SPECIFICATION left by the said George Hattersley
at the Office of the Commissioners of Patents, with his Petition,
on the 28th October 1852.
I, GEORGE HATTERSLEY, do hereby declare the nature of the said
Inventions for "A RADIATING HEARTH PLATE" to be as follows:-
The hearth plate is made independently of the fender, with two sets.
of bars of stamped bright steel or other metal, radiating from a centre-
determined by the curve of the front of the stove or grate in connection
with which it is intended to be used. The upper set of bars are fixed
to a frame, with spaces between them corresponding with their own
width, and to afford a large amount of reflecting and radiating surface
are convex on the upper superficies. The lower or second set of bars
may be flat or convex on the upper surface to suit individual tastes, but
are moveable; they are connected together by a frame which fits beneath
the frame to which the upper set of bars are attached, and the two
frames are so 'connected by means of rivets or screws that the lower
set of bars which fit or fill up the spaces between the upper bars may
be moved laterally under the fixed bars, or lowered vertically any re-

page_text: quired distance, and again screwed up or drawn back as far as may be
required to close the spaces between the upper bars. By this means
the ashes is wholly kept out of sight, cleanliness is secured, a large
amount of surface to aid in diffusing the hent is provided, and with
these is combined an ornamental hearth plate.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Hattersley in the Great Seal Patent
Office on the 28th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GEORGE HATTERSLEY, of Sheffield, in the County of York, Stove Grate
Manufacturer, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of October, in the
year of our Lord One thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Hattersley, Her special licence
that I, the said George Hattersley, my executors, administrators, and
"assigns, or such others as I, the said George Hattersley, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make,.use, exercisc,. and d
vend, within the United Kingdom of Great Britain and. Ireland, the
Channel Islands, and Isle of Man, an Invention for "A RADIATING
HEARTH PLATE," upon the condition (amongst others) that I, the said
George Hattersley, by an instrument in writing under my hand and
"seal, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
'cause the same to be filed in the Great Seal Patent Office within. six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said George Hattersley, do hereby
"declare the nature of my said Invention, and in what manner thic same
is to be performed; to be particularly described and ascertained in and
by the following statement, that is to say:

page_text: The hearth plate is made with two sets of bars (a, a, and b, b,) of
stamped bright steel or other metal, radiating from a centre or adjusted
to suit the curve of the stove or grate in connexion with which it is to be
used; it may be made independently of or in connexion with the fender.
The upper set of bars (a, a,) are fixed to a frame (c,) with spaces corre-
sponding to or about their own width, and to afford a large amount of
radiating and reflecting surface are convex on the upper superficies.
The lower or second set of bars (b, b,) may be either flat or convex on
the upper surface to suit the taste of individuals; they are fixed to
frames (z, z,) which fit beneath the frame (c.) to which the upper bars
(a, a,) are attached; these frames (2) are connected to the upper
frame (c,) by means of rivets or screws (e, e,) so as to be moveable,
either horizontally or vertically, as may be desired in the manner
following: To the upper set of bars are fitted the rivets or screws (e, e);
for these the lower set of bars (6, b) are to provide for a horizontal
motion slotted, or to provide for a vertical motion tapped. Thus the
lower set of bars which fit or fill up the spaces between the upper bars
(a, a.) may be moved laterally from f, to g, so as to be concealed by the
upper bars (a, u,) and again drawn back from g, to f, or by means of
thumb headed screws (h, k) may be lowered vertically to any required
distance, and again screwed up. By this Invention the ashes are kept
wholly out of sight, cleanliness is secured, a large amount of surface to
aid in diffusing the heat is provided, and with these advantages is com-
bined an ornamental hearth plate.
The improvements which I claim as my Invention are particularly
the introduction of the moveable or lower set of bars.
In witness whereof, I, the said George Hattersley, have hereunto
set my hand and seal, this Twenty-sixth day of April, in the
year of our Lord One thousand eight hundred and fifty-three.
GEORGE HATTERSLEY. (L.S.)
