Improvements in or relating to Steam and Hot Water Heating
Radiators.
We, JOHN THOMAS JACKSON, of 62, Gladstone Avenue, in the City of Toronto,
in the County of York, in the Province of Ontario, Mechanical Engineer, FERGUS
JAMES TRAVERS, of 1 Classic Avenue, in the said City of Toronto, Barrister-at-
Law, and JAMES ALFRED MILLS, of Rossin House, King Street West, in the said
City of Toronto, Barrister-at-Law, 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:-
This invention relates to certain new and useful improvements in or relating
to steam and hot water heating radiators, and the objects of the invention are
as follows:
(1.) To provide the radiator with a continuous and unimpeded circulation, so
that a uniform heat will be quickly established and maintained throughout the
entire radiator.
(2.) To provide each loop of the radiator with central inlet and outlet ports
separated by suitably arranged diaphragms, to divert the water into the proper
circulating channels, and fitting the lower part of one of the end loops with a
coupling to receive the flow pipe, and the lower part of the other end loop with
a coupling for the return pipe, and providing each of the end loops with a
vertical diaphragm above the central ports to cause the proper circulation of the
water through the said loops.
(3.) To couple the loops together centrally by means of a collar, fitted on the
hubs of the loops, surrounding the bore of the ports.
(4.) To provide the bottom of each loop with an opening all of the said openings
being in circulation with each other and with the flow or return pipes, in order
that the radiator can be completely drained.
(5.) To provide the top of each loop with an opening, the said openings being
in circulation with each other, and with a valve connected to one of the end
loops, in order that the stagnant air can be quickly exhausted from the radiator.
The invention consists essentially of the device hereinafter more fully set forth
and more particularly pointed out in the claims.

A represents one of the end loops, in which are formed two chambers a, a¹.
The upper chamber a is divided by a vertical partition b into two vertical water-
legs 61, 6, the vertical water-leg b' being in circulation with the lower chamber a¹,
and the other water-leg 6 being in circulation at the top with the water-leg b¹.

with the water-leg 6".
'1
T..represents a curved partition connected to the lower end of the vertical
partition b, and to the side of the shell of, the loop A, immediately below the
outlet L, the purpose of the partition T being to separate the water-leg 6 from
the lower chamber a', and deflect the water moving through the water-leg bu
through the outlet L into the next adjacent loop.
K represents an inlet for the loop A. The inlet K is located at the lower end
of the outer side of the loop A, and is fitted to receive the adjacent end of the
flow pipe.
H represents a drainage opening formed in the lower end of the loop A. One
end of the drainage opening H is provided with a male coupling E, which is
adapted to fit into a female coupling 1, in the lower end of the next adjacent
loop.
Q, represents an air-vent formed at the top of the loop A, and in communica-
tion with the water-legs 1, 11, through the vertical passage X. One end of
the air-vent Q is provided with a male coupling 7, which is adapted to fit into
a female coupling F, formed at the top of the next adjacent loop. The female
couplings D, Fare each adapted to receive a compressible ring or gasket, to
prevent leakage from the air-vent and drainage openings.

13 represents an intermediate loop, which consists of three water-legs, d, dɩ, d",
respectively. The water-leg d is located in the lower portion of the loop B.
The loop B.is provided with a central inlet opening M, in circulation with the
water-leg d. The lower end of the water-leg d is in circulation with the lower
end of the water-leg d', whilst the upper end of the water-leg d' is in circulation
with the upper end of the water-leg ". The loop B is provided with an outlet
opening Lin circulation with the water-leg-d..
The water-legs d, d" are separated from each other by a partition S, substan-
tially S-shaped in cross-section, and so arranged as to separate the inlet and
cutlet openings M, L respectively, placing the inlet opening M in circulation
with the water-leg d and the outlet opening L in circulation with the water-
leg, the, said water-legs d d. terminating with right angle bends or elbows
located centrally at the hubs R. The inlet opening M and the outlet opening L
are each surrounded by the hub R, one side of which is fitted with a female
connection r, to receive the male connection of the hub of the next adjacent
loop, and also to receive a compressible ring or gasket.
The lower end of the loop. B, is provided with a vertical passage Z connecting
with a horizontal drainage opening H, in circulation with the drainage opening H
of the loop A, whilst the top of the loop B is provided with an air-vent Q, in
circulation through the passage X with the top of the water-legs d', d, and
with the air-vent Q of the loop A.
We prefer to screw-thread the hubs of each of the loops with right and left
threads, and draw the loops together by means of a correspondingly threaded
coupling nut. We do not confine ourselves to any particular style of a coupling,
as we may employ any system of coupling the loops together that is now in
practical use. In practice, when the loops are placed together, the male con-
nections of the hubs R are inserted into the female connections r of the hub R
of the next adjacent loop, a compressible ring or gasket being interposed
between the male and female connections. The male connection of the air-vent Q
of one loop is inserted into the female connection of the air-vent Q of the next
adjacent loop, with a compressible ring or gasket interposed between these con-
nections; and the male connection of the drainage opening H of one loop is
inserted in the female connection of the drainage opening H of the next adjacent
loop, with a compressible ring or gasket, interposed between the connections; the
coupling nut or other coupling medium is then tightened, and the adjoining
loops forcibly brought together, causing the male connections to force the com-
pressible rings; into, the female connections, thus preventing any leakage from

provided with a draw-off cock, and the air-vents Q with an automatic valve.
The circulation of the water is as follows: The water enters the loop A by
means of the inlet opening K, passes up the water-leg a' into the water-leg bi,
around the top of the partition b, and down the water-leg 6, out through the
opening into the water-leg d of the next adjacent loop, passing downwards
through the water-leg d into the lower end of the water-leg d', up the water-
leg and into the water-leg ", passing down the water-leg out through
the opening L into the water-leg d of the next adjacent loop, and so on into
the end loop A¹, which is similar to the loop A, the circulation of the water,
however, being reversed from that of the loop A, viz.; passing upwards through
the water-leg down the water-leg to the water-leg a', and out through the
cpening K to the return pipe.
By means of the drainage openings H the water caused by the condensation of
steam, when the radiator is used as a steam radiator, can be conveniently drained
off. When the radiator becomes charged with stagnant air the air valve auto-
matically opens and allows the stagnant air to blow off.
Krepresents an outlet for the loop A¹, fitted to receive the exhaust or return
pipe.
