Year: 1881

page_text: LETTERS PATENT to Edward Haskell, Gas Engineer, of 280, Oxford Street,
London, W., and John Pitt Bayly, Architect, of 18, Fulham Place, Paddington,
for an Invention of "IMPROVED APPARATUS OR APPLIANCE FOR HEATING
BY GAS."
PROVISIONAL SPECIFICATION left by the said Edward Haskell and
John Pitt Bayly at the Office of the Commissioners of Patents on the
27th August 1881.
EDWARD HASKELL, Gas Engineer, of 280, Oxford St., London, W., and JOHN PITT
BAYLY, Architect, of 18, Fulham Place, Paddington, W. "IMPROVED APPARATUS
OR APPLIANCE FOR HEATING BY GAS."
This Invention consists of a contrivance to be fitted to ordinary coal grates,
stoves or ranges for heating rooms by gas without smoke or smell.
The object of the Invention is to heat by means of gas arranged in a form to be
fitted into the present register stoves of any shape, and consists of a metal case
perforated at the bottom, and fitted with rough rock shaped piece or pieces of glass
to resemble live coal between the bars of two or more tiers, one above the other, and
fixed to the outer case by means of catches, flanges, or rivets, the outer case being
fitted with a cover dropped into a socket or flange to hold the heat, the foul air
escaping through three or more tubes at the back of the lid or cover into a con-
denser of cold water, the reservoir of which is constructed at the back of the
bottom of the outer case or box.
Having now described the nature of this Invention, and how it is to be per-
formed, we therefore claim the following a
--
First. We claim the shape of the cover or lid which slopes towards the top of
the back of the cover or lid.
Second. We claim the rough rock shaped piece or pieces of glass to resemble live
coal.

page_text: Third. We claim the form of case to be able to fit it to any existing coal grate
stove, or range without removal.
A. is the back of the metal or fire clay case.
B is the reservoir to contain water.
C, C, C, are the tubes the foul air escapes through into the water reservoir.
D, D, are the sides of an ordinary grate.
E, E, E, are the bars of the grate that the apparatus drops into.
F is the cover that holds the heat.
G is the supply pipe.
H, H, are the tiers of rough rock annealed glass to resemble live coal.
I are the jets or burners of gas.
J is the cock that turns on or off the gas.

the said Edward Haskell and John Pitt Bayly in the Great Seal Patent
Office on the 23rd February 1882.

This Invention consists of a contrivance to be fitted to ordinary_coal grates,
stoves, or ranges for heating rooms by gas without smoke or smell. The object of
the Invention is to heat by means of gas arranged in a form to be fitted into the
present register stoves of any shape, and consists of a metal case perforated at the
bottom and fitted with rough rock shaped piece or pieces of glass to resemble live
coal, between the bars of two or more tiers, one above the other, and fixed to the
outer case by means of catches, flanges, or rivets, and heated by means of jets or
burners of gas, the outer case being fitted with a cover made of piece or pieces of
rough rock shaped glass also to resemble live coal to hold the heat, the foul air
escaping through one or more tubes at the back of the lid or cover into a
condenser of cold water, the reservoir of which is constructed at the bottom of the
stove.
Having now described the nature of this Invention, and how it is to be per-
formed, we therefore claim the following:-
First. We claim the shape of the cover or lid, which slopes towards the top of
the back of the cover or lid.
Second. We claim the rough rock shaped piece or pieces of glass to resemble live
coal.

J is the cock to turn on or off the gas.
In witness whereof, we, the said Edward Haskell and John Pitt Bayly,
have hereunto set our hands and seals, this Twenty first day of February,
in the year of our Lord One thousand eight hundred and eighty two.
