IMPROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED FOR HEATING OR WARMING ROOMS, GREENHOUSES, AND OTHER APARTMENTS.”

page_text: LETTERS PATENT to Thomas Stokoe, of Headingley, near Leeds, in the County
of York, for an Invention of "IMPROVEMENTS IN THE MEANS OR APPARATUS
EMPLOYED FOR HEATING OR WARMING ROOMS, GREENHOUSES, AND OTHER
APARTMENTS.”
PROVISIONAL SPECIFICATION left by the said Thomas Stokoe at the Office
of the Commissioners of Patents on the 11th October 1881.
"
THOMAS STOKOE, of Headingley, near Leeds, in the County of York.
IMPROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED FOR HEATING OR
WARMING ROOMS, GREENHOUSES, AND OTHER APARTMENTS."
I arrange a succession of hot air tubes, by preference one above the other, and in
communication with a chamber heated by a gas flame..
These tubes are enclosed in others, which are filled with water. The water tubes
are in communication with a boiler or hot water vessel surrounding the heated
chamber.
Above these tubes is arranged a box divided in its centre, the lower portion of
which also contains water which circulates through it, and the succession of water
tubes. Between the water and top of the box is the hot air passage, and the
hot air after passing along is conveyed downwards into an ordinary flue.
Small pipes are placed at various points forming a connection between the water
tubes to assist in the proper circulation of the water. The supply of gas and air
required for the same are controlled by suitable valves.
The above arrangement of apparatus throws out heat without any smell or
noxious gas arising therefrom, and the amount of heat is also readily controlled.
It may be used for heating greenhouses where the tenderest plants are grown, and
in rooms or apartments without any inconvenience to the occupants.

"IMPROVEMENTS IN THE MEANS OR APPARATUS EMPLOYED FOR HEATING OR

I arrange a succession of hot air tubes, by preference one above the other, and
in communication with a chamber heated by a gas flame.
These tubes are enclosed in others which are filled with water. The water tubes
are in communication with a boiler or hot water vessel surrounding the heated
chamber. Above these tubes is arranged a box divided in its centre, the lower
portion of which also contains water which circulates through it and the succession
of water tubes. Between the water and the top of the box is the hot air passage,
and the hot air after passing along it is conveyed downwards into an ordinary

Small pipes are placed at various points forming a connection between the water
tubes to assist the proper circulation of the water. The supply of gas and air
required for the same are controlled by suitable valves.
The above arrangement of apparatus throws out beat without any smell or
noxious gas arising therefrom, and the amount of heat is also readily controlled.
It may be used for heating greenhouses where the tenderest plants are grown, and
in rooms or apartments without any inconvenience to the occupants.
And in order that my Invention may be more completely understood, reference
is given to the accompanying Drawings, and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an end elevation; Fig. 2, a longitudinal section through A, B, Fig. 1 ;
and Fig. 3 a transverse section through C, D, Fig. 2.
The water
a is a chamber heated by gas, applied, as shewn, through atmospheric burner b.
In this chamber I also provide a perforated cone c, which is by preference made of
fire clay. This cone becomes intensely hot and assists greatly in heating the air.
This hot air from this chamber passes along the tube or tubes & in the direction
shewn by arrows, and through the opening e to the exterior of the building or
convenient flue. This hot air tube d is enclosed in another tube or tubes f, which
is in communication with a boiler or hot water vessel g surrounding the hot air
chamber a. Above these tubes is arranged a tank or box h, in which a supply of
water is provided for supplying the boiler g and the external tubes f.
contained therein circulates through the spaces between the internal tubes & and
the external tubes f, and in the boiler or hot water vessel g, such operation being
effected through the medium of the circulating tubes i. The division plate k is
for the purpose of separating or preventing all communication between the hot
air and the water; but when preferred the upper portion of the tank may serve as
a passage for the hot air, and the lower part may at the same time contain the
supply of water. But I find in practice that the arrangement shewn in the Drawing
is preferable. A small outlet tube is provided for the escape of steam.
ordinary water-guage; n is the opening through which water is admitted into the
tank; o is an opening through which air is admitted into the heating arrangement
and hot air chamber; p is the door, which may be of ordinary construction,
through which the heating arrangement is accessible; q is a cock fitted to the
boiler g for the purpose of employing it and the tubes f and i.

page_text: Having now described the nature of my said Invention, and described, with the
aid of Drawings, how the same may be carried into practice, I would have it under-
stood that I do not limit myself to the precise details or configuration of the parts
I have described and shewn, as the same may be varied or modified without
departing from the nature of my said Invention." What I do claim is,―
The arrangement and application of the hot air tube or tubes d enclosed within
or surrounded by the water tube or tubes f, in combination with the various parts
forming the apparatus for heating or warming rooms, greenhouses, and other
apartments, substantially as herein set forth.
In witness whereof, I, the said Thomas Stokoe, have hereunto set my hand
and seal, this Eighth day of April, in the year of our Lord One thousand
eight hundred and eighty two.
