LETTERS PATENT to George Livermore Shorland, of the Firm of
Shillito and Shorland, Manufacturing Ironmongers, of Stretford
Road, Manchester, in the County of Lancaster, for the Invention
of "IMPROVEMENTS IN GRATE BACKS FOR INCREASING THE EFFICIENCY OF
SHAM REGISTER AND OTHER Fire-grates.”
"
ealed the 10th October 1872, and dated the 19th April 1872.
PROVISIONAL SPECIFICATION left by the said George Livermore
Shorland at the Office of the Commissioners of Patents, with his
Petition, on the 19th April 1872.
I, GEORGE LIVERMORE SHORLAND, of the Firm of Shillito and
Shorland, Manufacturing Ironmongers, of Stretford Road, Manchester,
in the County of Lancaster, do hereby declare the nature of the said
Invention for “IMPROVEMENTS IN GRATE BACKS FOR INCREASING THE EFFICIENCY
of Sham RegisteR AND OTHER FIRE-GRATES,” to be as follows:-
LI
My Invention is applicable to the grates of fire-places employed to
warm the air in dwelling houses and in other buildings, and is par-

page_text: ticularly applicable to the description of grate known as the "sham
register," but may also be applied to other grates employed for a similar
purpose.
When applying my Invention to a fire-place which is to be fitted with
an ordinary "sham register" grate, I construct a hollow back piece formed
partly or wholly of cast iron, fire-clay, terra cotta, or other suitable
material, and provided with one or more passages at the lower end for
the inlet of air, and one or more passages at the upper end through
which the air flows into channels which convey it into the room in
which the fire-grate is fixed, or into another room or other rooms, as
desired.
When formed partly or wholly of cast iron, I make the part which
is towards the fire of cast iron, and I form thereon a number of fins or
projecting ribs, and I fix a plate of cast or wrought iron to the said part
so as to form an air channel, the said fins projecting into the said
channel and acting to warm the air flowing through the said channel.
When the said part which is towards the fire is made of terra cotta or
other material, fins may or may not be formed thereon, as found to be
convenient. I prefer that the air inlet or inlets may communicate with
a channel or with channels which convey air from the outside.
The improved back may either be a separate part applicable to various
descriptions or patterns of grates, or may be attached to or fitted with
a grate and front so as to be a component part of a complete grate.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said George Livermore Shorland in the Great Seal 2
Patent Office on the 19th October 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
LIVERMORE SHORLAND, of the Firm of Shillito and Shorland, of Stret-
ford load, Manchester, in the County of Lancaster, Ironmongers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of April, in the year of
8

page_text: our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Livermore Shorland, Her special
license that I, the said George Livermore Shorland, my executors, ad-
ministrators, and assigns, or such others as I, the said George Livermore
Shorland, 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, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
“IMPROVEMENTS IN GRATE BACKS FOR INCREASING THE EFFICIENCY OF SHAK
REGISTER AND OTHER FIRE-GRATES," upon the condition, amongst others,
that I, the said George Livermore Shorland, by an instrument in.
writing under my hand and seal, should particularly describe and
6 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 Livermore Shorland, do
O hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, and accompanying Drawings, that
is to say:-
My Invention is applicable to the grates of fire-places employed to
5 warm the air in dwelling houses and in other buildings, and is par-
ticularly applicable to the description of grate known as the sham
register, but may also be applied to other grates employed for similar
purpose.
When applying my Invention to a fire-place which is to be fitted with
Dan ordinary sham register grate, I construct a hollow back piece formed
partly or wholly of cast iron, fire-clay, terra cotta, or other suitable
material, and provided with one or more passages at the lower end for
the inlet of air, and one or more passages at the upper end through
which the air flows into channels, which convey it into the room in
which the fire-grate is fixed or into another room or other rooms as
desired.

channels which convey air from the outside of the building.

When formed partly or wholly of cast iron I make the part which is

may or may not be formed thereon, as found to be convenient. I prefer
that the air inlet or inlets may communicate with a channel or with
| channels which convey air from the outside of the building.
The improved back may either be a separate part applicable to various 10
descriptions or patterns of grates, or may be attached to or fitted with
a grate and front so as to be a component part of a complete grate.
In order that my said Invention may be fully understood, I will in
this place refer to the accompanying Sheet of Drawings wherein Fig. 1
represents a vertical section of a fire-place and fire-grate fitted with the 16
improved back, Fig. 2 representing a horizontal cross section of the
same, and showing the fire-grate and grate back in plan.
In the said Figures a is the aforesaid grate back formed of cast iron
and having the front portion curved so as to form both the sides and
the back of the fire-place. The said back is cast in the form of a 20
hollow box or casing and is formed with fins projecting into the air
space within the said back as herein aforesaid, one of the said fins
being shown at b. An inlet c for air is formed or provided at the lower
part of the said back, and two outlets for heated air communicate
with the pipes or air psssages d, d, at the upper end of the said back. 25
The said pipes are extended to any part of the room to be warmed,
or to any other part of the building, as may be required. The cool
or fresh air enters from the outside of the building through the
grating e and flows in the direction of the arrows through the back and
the pipes d, d.
Having now fully described and indicated the nature of my said
Invention and my method of carrying the same into practical effect, I
would in conclusion have it to be understood that I claim the cm-
ployment for the purposes therein indicated of the fire-back a formed,
30

page_text: fitted, and arranged substantially as herein-before set forth and indi-
cated.
In witness whereof, I, the said George Livermore Shorland, have
hereunto set my hand and seal, this Eighteenth day of October,
in the year of our Lord One thousand eight hundred and
seventy-two.
Signed and sealed by the said
George Livermore Shorland
