Improvements in Hot Water or Steam Radiators.
We, JOHN THOMAS JACKSON, residing at 62 Gladstone Avenue in the City of
Toronto, in the County of York, in the Province of Ontario, Mechanical Engineer, and
SAM JACKSON, residing at the same place, in the said City of Toronto, Moulder, and
JAMES ALBERT KEYES, residing at 551 Church Street, in the said City of Toronto,
Barrister-at-law, and FERGUS JAMES TRAVERS, residing at 1 Classic Avenue, 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 to steam or hot
water radiators, and the objects of our invention are as follows:-
1. To provide a radiator with a positive circulation which will be so constructed that
the steam or hot water cannot lio dead or stagnant within the radiator loops, but will
always be flowing onward and thereby cause a uniform system of heat throughout
the entire radiator, which greatly prevents cooling or condensation, the entire surface
of the radiator being equally effective in giving off heat, thus preventing unequal
expansion and contraction of metal, and will with less radiating surface produce more
heat than any of the radiators now in use.
2. To provide a radiator in which accumulated air can be readily drawn off from
within the entire radiator, and thereby prevent stagnant air from spoiling the effects
of the heat which should otherwise circulate through the building.
3. To provide a radiator that by simple and easy means the loops can be coupled or
stacked together and likewise uncoupled or taken apart within the space of their own
sittings without disturbing any of the loops except the one removed.
We attain these objects by means of mechanism illustrated in the accompanying
drawings, in which
Fig. 1 is a side view of circulating loop broken in section.
Fig. 2 is an edge view of circulating loop broken in section.
Fig. 3 is a lower end view of circulating loop cut in section.
Fig. 4 is a face view of flange joining face.
Fig. 5 is a face and sectional view of clamping ring.
Fig. 6 represents a sectional drawing of flange joint and clamping ring in position.
Fig. 7 is an edge view of clamping ring.
Fig. 8 represents a side view of joint exhibiting the inclined faces of flanges.
Similar letters of reference in the several figures refer to the same parts.
A, Fig. 1, represents an inlet by which steam or hot water is conducted into the
loop and directed or caused to circulate by aid of the diaphragm B, which is of a bent
shape similar to that of the letter "S" shewn by "B" on Fig. 3, and which is cast
ntegral within the lower end of the radiator loops forming a partition, thus preventing.
direct current of steam or hot water from passing along the bottom of the loops,
out directing the current around each loop through the entire radiator to the outlet D,
being at the opposite side of the loop from which the steam or hot water entered.

The small aperture at the lower end of the diaphragm B as shewn in Figs 1 and 2
allows drainage of water caused by the condensation of steam or otherwise, and further
may be used for the purpose of emptying the radiator of water when not in use.
tubular passage X as shewn in Figs. 1 and 2 is cast or constructed at the extreme top
of the loops and forms, when the loops are connected and the radiator completed, a
continuous tube or passage connecting with the inner chamber of the radiating loops,
by which accumulated and stagnant air can be readily drawn off from the entire
radiator, thereby causing complete freedom of circulation; the said tubular passage X
having matched connections as shewn by M and N in Fig. 2, in which connections is.
placed a small gasket, and the several loops of the radiator are held in position by a
small rod bolt passing through the entire length of the passage X of the radiator,
which said passage X terminates with a small escape valve or petcock and rosed nut
upon the outer end loops of radiator. The flange E, Fig. 4, is of matched joint facing
surrounding inlet A and outlet D, in Figs. 2 and 3; the said flange having two
notches cut in its outer edge as shewn by K on Fig. 4, to allow the lugs of clamp
nut F, as shewn in Fig. 5-there being four upon the outer edges of the said clamp
nut F, two upon each side projecting inwardly, corresponding with the notches in
flange E-to pass through and likewise allow the said lugs T of clamp nut F to travel
along the grooves ○ as shewn in Fig. 8. The back face of flange E is inclined, having
an inclined pitch of a screw thread shewn by P in Fig. 8, so that when the joint faces,
as shewn by A and D in Fig. 8, are brought together within the said clamp nut, and
the inward projecting lugs marked T upon the said clamp nut F passes through the
notches K in the flanges Fig. 4 a partial turn with a lever or wrench upon the clamp
nut F will make a most rigid connecting joint and one that will be perfectly water
tight. Connection of the different loops of the radiator can also be made by a right
and left hand socket as shewn in Figs. 9, 10, 11 and 12. The sectional view of the
clamp nut F in position is shewn in Fig. 6, where the flange faces A and D are
together, and the clamp nut F is in position. The said inward projecting lugs T
upon the clamp nut F, having their inner faces inclining, or wedge shaped, corresponding
with the inclined faces of said flange E, thereupon the clamp nut F being turned, the
inward projecting lugs T will pass along the grooves O, Fig. 8, thus being a direct
and intense pressure upon the joint faces and forming a connection which will be
water and steam tight.
Having now particularly described and ascertained the nature of our said invention,
we hereby declare that what we claim is :
1. The improvements in or relating to heating radiators hereinbefore described and
illustrated in Figs. 1, 2, and 3 of the drawings.
2. The improvements in or relating to heating radiators hereinbefore described and
illustrated in Figs. 4, 5, 6, 7 and 8 of the drawings.
3. The improvements in or relating to heating radiators hereinbefore described and
illustrated in Figs. 10, 11 and 12 of the drawings.
4. In a radiator a diaphragm B cast integral therewith being part of the lower end
of radiator loops forming a partition by which means a positive and constant flow
or circulation is attained, said diaphragm or partition B having a small aperture at
the bottom thereof by which means the radiator is drained, substantially as set forth.
5. In a radiator the construction of a tubular passage along the top of loop of
the radiator by which stagnant air can be released or drawn off, substantially as set
forth.
6. The combination with a radiator, a flange E having matched joint faces surrounding
inlet A and outlet D, said flange E having notches K in its outer edge. I, the back
faces of said flange E being inclined throughout, forming the pitch of a screw thread,
substantially as set forth.
7. The combination with a radiator, a flange E having matched joint faces surrounding
inlet A and outlet D forming grooves O, said flange E having notches K in its outer
edge I providing a passage for the inward projecting lugs upon clamp nut F, said.
