PROVISIONAL SPECIFICATION left by the said Benjamin Looker at the
Office of the Commissioners of Patents, with his Petition, on the
5th May 1874.
I, BENJAMIN LOOKER, of Kingston-upon-Thames, in the County of
Surrey, Brick and Tile Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN HEATING APPARATUS," to be as
follows:-
This Invention relates to improved arrangements of stoves for heating,
specially applicable where gas is the source of heat employed, and such
arrangements consist of a stand or base which may be of fire-clay or of
metal. This stand or base has a number of air openings for supplying

page_text: air for sustaining the ventilating action of the stove. Upon this stand a
case is fitted or placed, formed by preference of fire-clay, with a
ventilating or air shaft in the centre, which has air communication
through the base, and in the substance of the case a number of heat
shafts are situate.
The heater or heaters, gas burners by preference, are placed at the
bottom or near the bottom of each heat shaft, and communicate with a
heat chamber or passage at top of the stove, the ventilating passage
being covered at top. At the lower part of each heat shaft of the case
are air openings for supporting combustion, and orifices for the emission
of hot air are made through the case between the said heat shafts so as
to allow hot air acted upon by fresh air from the ventilating passage to
pass into the apartment or place to be heated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Benjamin Looker in the Great Seal Patent Office
on the 5th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
LOOKER, of Kingston-upon-Thames, in the County of Surrey, Brick and a
Tile Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her
Letters Patent, bearing date the Fifth day of May, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Benjamin Looker, Her special licence
that I, the said Benjamin Looker, my executors, administrators, and
assigns, or such others as I, the said Benjamin Looker, 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

page_text: Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
HEATING APPARATUS," upon the condition (amongst others) that I, the said
Benjamin Looker, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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 Benjamin Looker, 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 :-
The object of my said Invention is to provide improved stove arrange-
ments wherein ventilation, effectiveness, and economy of fuel are
specially provided for, suited for gas though adaptable for stoves burning
other fuel.
The means whereby I carry out my said object and effectuate my said
Invention are as follows:-I construct a stand or base which may be of
fire-clay or metal with a number of air openings for sustaining the
ventilating action of the stove. Upon this stand a case is fitted or
placed, formed by preference of fire-clay with a ventilating or air shaft.
in the centre which has air communication through the base, and in the
substance of the case a number of heat shafts are situate.
The heater or heaters (say gas burners) are placed on the bottom or
near the bottom of each heat shaft, and communicate with a heat
chamber or passage at the top of stove, the ventilating passage being
covered at top. At the lower part of each heat shaft of the case are air
openings for supporting combustion, and orifices for the emission of hot
air are made through the case between the said heat shafts so as to
allow the hot air acted upon by cold air from below the ventilating
passage to pass into the place or apartment to be heated.
This apparatus may be utilised for cooking by having the top or upper
part removed and applying the cooking utensils or vessels.
Having thus particularly described and ascertained the nature and
object of my said Invention, and indicated in what manner the same
•

page_text: may be performed or put in practice, I will now in further compliance
with the aforesaid condition in the said Letters Patent contained proceed
to more fully and particularly describe and ascertain in what manner
the same is to be performed or carried out in practice, by referring to the
DESCRIPTION OF THE DRAWINGS.
Figure 1, external view; Figure 2, vertical section; Figure 3, section
on line A, B, (Fig. 2).
Figure 4, front view of modified form which may be placed in ordinary.
fire-grates; Figure 5, section on line A, B, (Fig. 4); Figure 6, section I
on line C, D, (Figure 4).
In these Figures a is stand or base with air openings 6; c is the
ventilating or air shaft connected with the base; d are gas burners
which are placed at the bottom part of each flue or heat shaft d'; e arc
the openings for supplying the air for combustion to the burners; fare 1
the orifices for allowing the heated air to pass through into the room or
apartment; g is cover for the air or ventilating shaft; his cover to the
stove.
The action is as follows:-The air passes through openings 6 in the base
of stove and passes up into shaft c, and by means of the heat imparted 2
by the gas burners d in the flues d' the heated air in passing from the
shaft c through the orifices of becomes heated and passes out through
said orifices into the room or apartment.
In the case of the modified form shown in Figs. 4, 5, and 6, the heat
from the fuel passes up the flues d¹, and the air to be warmed passes up 2
the shaft c and out into the room or apartment by orifices f. In this
form ordinary fuel or gas may be used, and also the lower part may
be made so as to give the effect of what is termed the cheerful gas
stove.
Having thus particularly described and ascertained the nature and a
object of my said Invention, and in what manner the same is to be
performed or carried out in practice, I hereby declare that I claim the
said improvements in heating apparatus as herein-before described and
illustrated by the Drawings accompanying these Presents, it being

page_text: understood that I do not claim nor do I limit or confine myself to the
use of the exact details shown in the said Drawings, and described by
reference thereto, as the same may be varied without departing from the
essential characteristics of my said Invention.
In witness whereof, I, the said Benjamin Looker, have hereunto
set my hand and scal, this Fourth day of November, in the
year of our Lord One thousand eight hundred and seventy-
four.
