I, GEORGE HARVEY, of Thorncliffe Lane, Chapeltown, near Sheffield in the County
of York, Iron Works Manager, do hereby declare the nature of this invention to be
as follows:
This invention relates to Coils or Radiators, through which steam or hot water is
made to pass or circulate for the purpose of radiating heat to a room or other place
which it is desired to warm.
It has for its object a novel method of making the paris of such Radiators so that
they are cheap and easily put together, and very effective for the purpose required.
In such heating radiators heated as described by hot water or steam, it is some-
times usual to arrange passages or channels through which air is made to pass in
contact with the heated surfaces, the air after being thus heated passing into and
circulating in the room or place which is to be warmed.
My invention consists of a novel method of casting the pipes through which the
hot water or steam passes and the air pipe or channel through which the air passes
and is warmed, in a single piece, cach such piece being provided with joints or attach-
ments by which two or more can be fitted together and firmly connected so as to form
a larger or smaller heating coil or radiator as the circumstances in which it is to be
used may require.
For this purpose I cast, of cast iron or other metal, a compound pipe preferably
rectangular or nearly so in cross section, and divided into a central and two outer
rectangular pipes by two longitudinal partitions forming part of it and extending
from end to end.
The central pipe so formed is open at its upper and lower ends, so that air admitted
at its lower end passes up and escapes freely at the upper end; whilst the two side
pipes are closed at both ends but have lateral openings into them at top and bottom
upon each side of the central air pipe. These lateral openings extend from side to
side of the casting, so that if a number of the compound castings described are
ranged together side by side, the lateral openings extend through them all, one being
upon each side of the central air pipe both at the top and bottom.

page_text: At the top and bottom or sides of the castings I arrange lugs or brackets through
which bolts pass by means of which all the castings can be strongly drawn together
and attached, and I form the faces round the lateral apertures at the top and bottom
of such form that when bolted together as described the joints between the castings
can be mado steam and water tight.
The outer compound pipes of each coil or radiator, have the lateral passages both
at top and bottom closed upon the outer side, so that the hot water or steam space in
the entire coil is continuous but closed except where a suitable admission pipe at one
end and exit pipe at the other, for the steam or hot water are provided.
Air can be admitted from a room to the bottom of the air passages through thic
coil by placing the latter on a suitable stand and fitting it with a ventilator in front;
or cold air can be admitted from the outside of a building through an air passage cut
through the wall and communicating with an aperture under the base of the coil or
radiator. Upon the top of the coil may be arranged a moulded ornamental box or
cover having a grated top through which the air escapes into the room after having
been heated by passing up through the central air channels in the coil.

page_text: I. GEORGE HARVEY, of Thorncliffe Lane, Chapeltown, near Sheffield, in the County
of York, Ironworks Manager, do hereby declare the nature of this 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)
This invention relates to Coils or Radiators, through which steam or hot water is
made to pass or circulate for the purpose of radiating heat to a room or other place
which it is desired to warm.
It has for its object a novel method of making the parts of such Radiators so that
they are cheap and easily put together, and very effective for the purpose required.
In such heating radiators heated as described by hot water or steam, it is some-
times usual to arrange passages or channels through which air is made to pass in
contact with the heated surfaces, the air after being thus heated passing into and
circulating in the room or place which is to be warmed.
My invention consists of a novel method of casting the pipes through which the
hot water or steam passes and the air pipe or channel through which the air passes
and is warmed, in a single piece, each such piece being provided with joints or attach-
ments by which two or more can be fitted together and firmly connected so as to form
a larger or smaller heating coil or radiator as the circumstances in which it is to be
used may require.
The accompanying drawing is in illustration of my invention. Figure 1 is an end
view of one of the compound pipes. Figure 2 is a longitudinal section of three pipes
connected together. Figures 3 and 4 are horizontal sections through the pipes at
different heights. Figure 5 is a front view on a smaller scale of the entire apparatus,
and figure 6 is a transverse section through the same. The same letters of reference
indicate similar parts in the several figures.
In order to put my invention in operation I cast of iron or other metal, a compound
pipe a, a, a, preferably rectangular or nearly so in cross section and divided into a
central pipe b and two outer more or less rectangular pipes c, c, by two longitudinal
partitions d, d forming part of it (as shewn in figures 3 and 4) and extending from
end to end.
The central pipe 6 so formed is open at its upper and lower ends, so that air
admitted at its lower end passes up and escapes freely at the upper end; whilst the
two side pipes c, c, are closed at both ends but have lateral openings e, e, e, e, into
them at top and bottom upon each side of the central air pipe b. These lateral
openings e extend from side to side of the casting (as shown in figure 4), so that if a
number of the compound castings described are ranged together side by side (as
shewn in figures 2, 3, 4, and 5) the lateral openings extend through them all, one being
upon each side of the central air pipe 6 both at the top and bottom.

page_text: At the top and bottom or sides of the castings I arrange lugs or brackets / through
which bolts g pass by means of which all the castings a, a, a, can be strongly drawn
together and attached, and I form the faces at round the lateral apertures e at the
top and bottom, of such form that when bolted together as described the joints
between the castings can be made steam and water tight.
The outer compound pipes of each coil or radiator, have the lateral passages e both
at top and bottom closed upon the outer side (as shewn in figure 4 at a¹) so that the
hot water or steam space in the entire coil is continuous but closed except where a
suitable admission pipe at one end and exit pipe at the other, for the steam or hot
water, are provided.
Air can be admitted from a room to the bottom of the air passages & through the
coil by placing the latter on a suitable stand and fitting it with a ventilator or opening
in front or at the sides as illustrated in figures 5 and 6; or cold air can be admitted
from the outside of a building through an air passage cut through the wall and
communicating with an aperture under the base of the coil or radiator.
Upon the top of the coil may be arranged a moulded ornamental box or cover i,
figures 5 and 6, having a grated top through which the air escapes into the rooni
after having been heated by passing up through the central air channels in the
. coil.
Any number of the compound pipes described may be bolted together to form
radiators of any desired size, and they may be made as ornamental as desired.
I do not claim generally the use of pipes connected together so that air admitted
through or between them is heated in its passage, but having now particularly
described and ascertained the nature of my said Invention and in what manner
the same is to be performed, I declare that what I claim is :-
In a heating coil or radiator, the combination of a sufficient number of compound
pipes each formed in a single piece having a double connected waterway and an air
pipe or passage through it, the double waterways through the several pipes composing
the coil forming a continuous passage, substantially as and for the purpose described
and shewn in the drawings.
