Chancery Lane in the County of Middlesex, Fellow of the Chartered Institute of

This Invention relates to apparatus which is capable of use exclusively as a
steam-heater or exclusively as a water-heater or as a part water and part steam
heater. To this end I may employ a radiator having a series of connected loops,
vertical steam leading pipes extending through a number of the loops and having
open upper ends, a steam feed pipe communicating with the steam lead-
ing pipes and also having communication with the loops of the radiator
whereby steam may be admitted to the radiator either directly to the loops
or through the steam leading pipes and whereby also any amount of water may
be retained within the loops so as to enable the radiator to be used either exclusively
as a water-heating apparatus or as part water and part steam heater.
The loops are in communication with each other at each end and are supported
by legs and an air discharge valve commands an orifice in the upper end of one
loop. In the lower rear portion of all the loops, excepting the end loops, are a
series of vertically extending openings into which elbows are screwed, each elbow
having screwed into its vertical upper portion a steam leading pipe extending
upwardly through the rear section of each respective loop, the upper ends of the
pipes terminating a short distance below the open upper ends of the loops. The
elbows are each turned forwardly and are respectively provided with right and left
hand threaded thimbles which extend transversely of the radiator and are connec-
ted to a pipe by means of unions. The end thimbles are respectively connected
by tees with pipes the one leading to a valve which in turn communicates with,
and controls, an outlet pipe while the other pipe is connected by means of an elbow
to a valve which controls an opening into one of the end loops of the radiator. In
this manner,
the opening of the one valve and the closing of the other valve will
permit the steam to pass through the leading pipes and be discharged from the
open upper ends thereof, the air discharge valve having been previously opened

the radiator the water of condensation settles in the lower portion thereof and
gradually rises until it reaches the level of the upper ends of the steam leading
pipes. The passage of the steam through the said pipes keeps the water hot and
in this way the radiator is made to heat exclusively by hot water. The surplus
water of condensation returns through the leading pipes, past the valve, and out
via the exit pipe.
To convert the radiator into a part steam heater, the water contained within the
radiator is withdrawn by opening the valve. Supposing that the water is half
withdrawn, the steam still heats the water and the steam in the upper portion of

valve left open, so as to prevent the accumulation of more water, the radiator is
converted into an exclusively steam heater.
The improvements can be readily applied to existing radiators.

Improvements in Radiators."
I, ALEXANDER MELVILLE CLARK of the Firm of A. M. & Wm. Clark of 59.
Chancery Lane in the County of Middlesex, Fellow of the Chartered Institute of
Patent Agents; do hereby declare the nature of this Invention (a communication
to me by Frederick Bason of 1040. 76th Street, Chicago, in the County of Cook
and State of Illinois, United States of America, Inventor:) and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement;-.
The object of this Invention is to provide a radiator in which both steam and
water are used, forming an apparatus capable of use exclusively as a steam-heater
or exclusively as a water-heater or as a part-water and part-steam heater.
In attaining this end I may employ a radiator having a series of connected
loops, vertical steam leading pipes extending through a number of the loops and
having open upper ends, a steam feed pipe communicating with the steam leading
pipes and also having communication with the loops of the radiator, whereby
steam may be admitted to the radiator either directly to the loops or through the
steam leading pipes, and whereby also any amount of water may be retained within
the loops, thus enabling the radiator to be used exclusively as a water heating
apparatus or as a part water and part steam heater.
The invention will be fully described hereinafter and its scope defined in the
claim.
Reference is to be had to the accompanying drawings which illustrate a species
of my invention and which form a part of this specification, in which drawings
similar characters of reference indicate corresponding parts in all the Figures.
Figure 1 is a vertical longitudinal section of my invention;
Figure 2 is a cross section thereof on the line 2-2 of "Figure 1; and
Figure 3 is a plan view of the connections for the radiator in Figures 1 and 2.
The loops 15 may be of the usual construction, they being in communication
with each other at each end and supported by legs 16. An air discharge valve 17
commands an orifice in the upper end of the loop. Formed in the lower rear
portion of all of the loops excepting the end loops, are a series of vertically extend-
ing openings into which elbows 18 are screwed. Each elbow has screwed into.
its vertical upper portion a steam leading pipe 19, such pipes extending upwardly
through the rear section of each respective loop, the upper ends of the pipes ter-
minating a short distance below the open upper ends of the loops.
The elbows 18 are each turned forwardly and are respectively provided with
right and left-hand threaded thimbles 20. The thimbles 20 extend transversely
of the radiator and are connected to a pipe 21 by means of unions 22. The end
thimbles 20 are respectively connected by tees 23 with a pipe 24 and a pipe 25.
The pipe 24 extends to a valve 26 in turn communicating with a pipe 27, while
the pipe 25 is connected to a valve 28 by means of an elbow 29. The valve 28

page_text: controls an opening into one of the end loops of the radiator, and the valve 20
controls the pipe 27.
With the radiator constructed as above described, the opening of the valve 26
and the closing of the valve 28 will permit the steam to pass through the leading
pipes 19 and be discharged from the open upper ends thereof, the valve 17 having
been previously opened to permit the escape of the air within the radiator. As the
steam condenses within the radiator the water of condensation settles in the lower
portion thereof and gradually rises until, as shown in the drawings, it reaches the
level of the upper ends of the pipes 19. The passage of the steam through the
pipes 19 keeps the water hot and in this way the radiator is made to heat exclusively
by hot water. The surplus water of condensation returns through the leading
pipes 19, past the valve 26 and out via the pipe 27.
To convert the radiator into a part steam heater, the valve 28 will be opened
whereupon the water within the radiator will be withdrawn. Supposing now that
the water is half withdrawn, it will be seen that the steam still heats the water and
the steam in the upper portion of the radiator will furnish further heat. If the
water is entirely withdrawn and the valve 28 left open so as to prevent the accumu-
lation of more water, it will be seen that the radiator is converted into an ex-
clusively steam-heater.
By means of the peculiar connections for the steam pipes, I provide a radiator
which will be neat in appearance since all of the connections are hidden beneath
the radiator. This construction also permits readily applying the invention to
radiators not previously built for it.
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,
A radiator having a series of loops, communicating with each other and having
an air outlet orifice at the upper portion of one loop, a series of leading pipes ex-
tending longitudinally througa the rear run of a number of the loops, the leading
pipes extending downwardly through the lower portions of the loops, elbows
beneath the radiator with which the leading pipes respectively communicate, the
elbows turning forwardly from the leading pipes, a pipe running longitudinally
beneath the forward portion of the radiator, the pipe having communication
with the elbows, an additional pipe in communication with the said longitudinal
pipe, the additional pipe communicating directly with the lower portion of the
interior of the radiator, and a valve for said additional pipe, substantially as
described.
