We, ALEXANDER DONALD MACKENZIE and GEORGE GREIG MONCUR both of Upper
Grove Place, Edinburgh in the County of Mid-Lothian, Heating Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in that class of radiators for heating purposes
in which hot water or steam circulated through a coil of pipes is employed as the
heating medium and the apparatus constituting the invention consists of a hollow
base to the upper side of which a series of return pipes is connected. The two ends
of each pipe are respectively formed with spigots which pass into or through holes
made to receive them in the top of the base the joint being made water or steam tight
by means of asbestos, leather, india rubber or other equivalent packing. Each return
pipe is secured to the base by a bolt which passes through a hole made in a solid part
extending from the side of one end to that of the other the said bolt also passing down
through a vertical sleeve cast at the interior of and extending from the top to the
bottom of the hollow base a nut being screwed on to the lower end of the bolt and by
this arrangement the bolts do not pass through or come in contact with the water or
steam. All the pipes of the series constituting the radiator are in free communication
through the hollow base and communication is or may also be made at the top of the
radiator between the pipes by means of short connecting chambers or tubes one side
or end of each of which has a spigot entering a faucet in one vertical pipe whilst its
other side or end has a faucet into which a spigot made on the next vertical pipe of
the series enters or the joint between the connecting chambers and the return pipes
may be made in any other convenient manner.
Besides the said connection at the top of the tubes which is also for purposes of
circulation all the tubes constituting the coil of the radiator are held or braced together
at the top by a horizontal bolt or bolts passed through a palm or solid part mad

page_text: between the ascending and descending legs or parts of the end tubes of the coil and
under the water or steam space so that in the case of this bolt also it does not come in
contact with or pass through the water or steam space.
The hollow base is or may be raised from the ground or floor level by means of feet
or supports these being conveniently attached to the base where they occur by the
same bolts which secure the open ends of the returned pipes to the top of the base
as before set forth.

page_text: We ALEXANDER DONALD MACKENZIE and GEORGE GREIG MONCUR both of Upper
Grove Place Edinburgh in the County of Mid-lothian, Heating Engineers 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 improvements in that class of radiators for heating
purposes
in which hot water or steam circulated through a coil of pipes is employed
as the heating medium.
On the accompanying drawings figure 1 is a side elevation, figure 2 a horizontal
section, figure 3 an end elevation, figure 4 a longitudinal section on the line a a
figure 2 and figure 5 a cross section on the line bb figure 2 of the improved radiator
constructed in accordance with our said invention. As seen by these figures the
apparatus consists of a hollow base c to the upper side of which a series of return
pipes d is connected. The two ends of each pipe are respectively formed with spigots e
as seen at figures 4 & 5 which pass into or through holes made to receive them in
the top of the base c the joint being made water or steam tight by means of
asbestos, leather, india-rubber or other equivalent packing. Each return pipe is
secured to the base by a bolt f which passes through a hole made in a solid part g
connecting the two ends of the pipe together the said bolt also passing down through
a vertical sleeve / cast at the interior of and extending from the top to the bottom of
the hollow base ca nut i being screwed on to the lower end of the bolt and by this
arrangement the bolts do not pass through or come in contact with the water or
steam. All the pipes of the series constituting the radiator are in free communication
through the hollow base and communication is or may also be made at the top of the
radiator between the pipes by means of short connecting tubes j formed at one side
of each return pipe the said tubes entering a spigot k made at one side of the next
return pipe that is to say each return pipe d excepting the terminal ones of the series
has a spigot k at one side and a tube at the other side of its upper end.
Besides the said connection at the top of the return pipes d which is also for
purposes of circulation all the tubes constituting the coil of the radiator are held or
braced together at the top by a horizontal bolt or bolts passed through a palm or
solid part m made between the ascending and descending legs or parts of the end
pipes d of the coil and under the water or steam space so that in the case of this bolt
also it does not come in contact with or pass through the water or steam space.
The hollow base c is or may be raised from the ground or floor level by means of
feet or supports n these being conveniently attached to the base where they occur by
the same bolts-which secure the open ends of the returned pipes d to the top of the
base as before set forth.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a radiator for heating purposes constructing and arranging the several parts
substantially as hereinbefore described with reference to the drawings annexed.
2. In a radiator for heating purposes and wherein return pipes are employed con-
necting the said pipes to the base by bolts passed through solid parts and whereby
the said bolts are preserved from contact with the water or steam substantially as
described with reference to the accompanying drawings.
3. In a radiator of the class set forth and wherein thore is intercommunication
between the upper ends of the return tubes bracing all the tubes of the radiator together
by a bolt or bolts passed through solid parts on the end tubes the said bolts throughout
their lengths being outwith the said communication substantially as and for the
purpose described with reference to the accompanying drawings.
