IMPROVEMENTS IN APPARATUS FOR WARMING ROOMS AND BUILDINGS
Year: 1882

page_text: LETTERS PATENT to Edwin Hopgood of Partlands Avenue Rydo in the
County of Hants and Edward Jenner of Belgrave Mansions Grosvenor
Gardens in the County of Middlesex for an Invention of "IMPROVEMENTS IN
PROVISIONAL SPECIFICATION left by the said Edwin Hopgood & Edward
Jenner at the Office of the Commissioners of Patents on the 22nd December
1882.
"
EDWIN HOPGOOD of Partlands Avenue Ryde in the County of Hants and
EDWARD JENNER of Belgrave Mansions Grosvenor Gardens in the County of
Middlesex "IMPROVEMENTS IN APPARATUS FOR WARMING ROOMS AND BUILDINGS'
This Invention has for its object improvements in apparatus for warming rooms
and buildings.
We combine with an ordinary open stove or fire place a system of hot water
circulation.
Our arrangement is as follows:-we provide small upright boxes or cases by
preference of copper one on either side of the fire basket. We connect these boxes
together by several curved horizontal copper pipes passed behind the fire in such a
position as to be effectively heated by it. We lead wrought iron pipes away from
the stove to the place or room in which it is desired that the heat should be given
off and there wo dispose so much pipe as will suffice to dissipate the heat whilst
the temperature in the system remains below the boiling point.
At the stove the ends of the pipe are connected the one to the bottom of one of
the side boxes and the other to the top of the other box. An air pipe or vent is
provided at the highest part of the system and suitable arrangements are made for
the supply of water.
In some cases I dispense with the boxes mentioned above and substitute a
serpentine coil at the back of the fire basket.

EDWIN HOPGOOD of Partlands Avenue Ryde in the County of Hants and
EDWARD JENNER of Belgrave Mansions Grosvenor Gardens in the County of
Middlesex "IMPROVEMENTS IN APPARATUS FOR WARMING ROOMS AND BUILDINGS
This invention has for its object improvements in apparatus for warming rooms
and buildings.
We combine with an ordinary open stove or fire place a system of hot water
circulation.
Our arrangement is as follows:-we provide small upright boxes or cases by
preference of copper one on either side of the fire basket. We connect those boxes
together by several curved horizontal copper pipes passed behind the fire in such a
position as to be effectively heated by it. We lead wrought iron pipes away from
the stove to the place or room in which it is desired that the heat should be given
off and there we dispose so much pipe as will suffice to dissipate the beat whilst
the temperature in the system remains below the boiling point.
At the stove the ends of the pipe are connected the one to the bottom of one of
the side boxes and the other to the top of the other box. An air pipe or vent is
provided at the highest part of the system and suitable arrangements are made for
the supply of water.
In some cases we dispense with the boxes mentioned above and substitute a
serpentine coil at the back of the fire basket.
Figure 1 shows a front view partly in section Figure 2 a plan and Figure 3 a
vertical section of apparatus arranged as above described.
A. A. are the upright boxes connected by several horizontal pipes B. The lower
end of one box is formed with a nozzle C projecting from it to which the end of a
wrought iron pipe forming the return pipe of the system of hot water pipes to be
heated may be coupled and the upper end of the other box is similarly formed
with a nozzle D to which another similar pipe may be coupled. This pipe is
preferably led upwards to a distance of about 5 or 6 feet from the floor level and
then led out through the chimney breast and from thence around the room or
place to be beated or to any assemblage of pipes situated at any point where it is
desired that heat should be given off.
The upright boxes A and connecting pipes B are placed at the back of the fire
basket and are heated by the fire contained therein. We also preferably connect
the front of the lower part of one box to the front of the lower part of the other
box by a pipe G as shewn to give greater heating surface. This pipe projects
somewhat into the fire place and lies just above the top of the fire bars.
From the top of the pipe connected to the nozzle D an air pipe or vent is led
upwards to allow of escape of steam.
Preferably we place on this pipe an enlarged chamber such as shewn at Figure 4—
the steam pipe E enters this chamber and rises up for a distance in it. Across the
chamber is placed a diaphragm F at a height slightly above the top of the steam
pipe E. Through this diaphragm openings are made near its circumference for
the escape of steam as shewn in the plan view of this diaphragm at Figure 4* and
a steam pipe is led for a short distance upwards from the top of the chamber.
This arrangement prevents water being injected out from the steam pipe and so
avoids loss of water and damage that might arise from water being ejected from
the steam pipe.

page_text: At Figures 5. 6 and 7 is shewn a serpentine coil of pipes which may be used in
place of the boxes and connecting pipes above mentioned. This coil of pipes is by
preference of copper. At its lower end it is formed with a union joint at A to
which the return pipe of the system of hot water pipes contained in the room may
be coupled and with another union joint B at its upper end to which the outflow
pipe is to be coupled.
The lower bends or portions of the coil of pipes lie just above the fire bars the
other bends or portions lie against the back of the fire basket.
Having thus described the nature of our invention and the manner of performing
the same we would have it understood that we claim :-
First. The combination of apparatus for warming rooms and buildings sub-
stantially as herein described with reference to Figures 1. 2 and 3 of the
Drawings.
Second. The combination of apparatus for warming rooms and buildings sub-
stantially as herein described with reference to Figures 5, 6 and 7 of the
Drawings.
In witness whereof I the said Edward Jenner have hereunto set my hand
and seal this twenty first day of June in the year of our Lord One
thousand eight hundred and eighty threo.
