Improvements in Radiators.
I, THOMAS TANGNEY, of South Superior, in the County of Douglas and State
of Wisconsin, United States of America, Manufacturer, 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 radiators designed for use in connection
with steam or hot water heating, and the objects I have in view are to dispense
entirely with the ordinary nipples and screw-threaded connections or screw-threaded
fastenings that are ordinarily used for securing the several sections of the radiator
together, and therefore doing away with the extra work that such a construction
necessitates; and to this end I provide a radiator consisting of separate sections
that may be put together without any fitting or working of the parts and which
may be used just as the castings are made.
The invention consists generally in a radiator consisting of separate sections
provided with clamping devices for securing them together and with joints that can
be fitted together by the use of ordinary packing.
The invention will be more readily understood by reference to the accompanying
drawings, forming a part of this Specification, in which :-
Fig. 1 is an end elevation of a portion of a radiator constructed in accordance
with my invention.
Fig. 2 is a vertical section of the same.
Fig. 3 is a side elevation showing a different form of joint and different coupling
device, the lower portion of the radiator being in section.
Fig. 4 is an end elevation of one of the sections shown in Fig. 3.
Fig. 5 is a detail section showing another form of joint.
Figs. 6 and 7 are details of two forms of clamping devices.
Fig. 8 is a section of a portion of one loop of the radiator, showing one
construction of the joint.
Figs. 9 and 10 are plan views of portions of the radiator showing the clamps
applied thereto.
Fig. 11 is a detail of one of the clamps.
Fig. 12 is a plan section showing the arrangement of the interior clamp.
Fig. 13 is a plan view of several sections of the radiator showing another form
of clamp.
Fig. 14 is a side elevation of the upper portion of the radiator shown in Fig. 13.
In all the figures of the drawings, 2 represents the loops or sections that are used
to make up the radiator, said sections being preferably all alike and capable of
being joined together so as to make radiators of any desired size.
These loops may
be connected together both at the top and bottom, as shown in Figs. 1 and 2, or
they may have a connection at the bottom only, as shown in Figs. 3 and 4.
I have shown several forms of joints between the radiator sections, any one of
which may be used. As shown in Figs. 1 and 2 I provide at one side of the
radiator section a conical recess 5 and at the other side a conical projection 7.
These projections and recesses on the adjoining sections fit into each other as shown
in Fig. 2. In Fig. 8 I have shown an enlarged detail with a similar form of
projection and recess, except, as here shown, I have provided the recess with the
longer bearing surface by extending it inwardly into the interior of the loop. The
sections may be placed together with these projections and recesses in connection
with each other and with any suitable packing material arranged between them or
in place of using the conical projection and recess I may provide the annular
grooves 11 aud annular ribs 13, adapted to engage therewith, as shown in Fig. 3

page_text: and use a suitable packing therewith, or I may use a shoulder projection adapted
to fit into the shoulder recess, as shown in Fig. 7, or I may use an intermediate
coupling piece 15, and this coupling may be provided with annular grooves or
shoulders to engage corresponding grooves or recesses in the radiator section, or it
may have the conical end adapted to engage a conical recess in the section, as
shown in Fig. 5, the radiator section being placed together with suitable packing in
the joints and being pressed firmly together by means of suitable clamping device.
They are then locked together by means of suitable keys. I prefer to arrange
these keys in the interior of the loops as shown in Figs. 1, 2 and 12.
As here shown, each section is provided at each side and at the points near the
top and bottom of the loop with the inclined ribs 19 having the narrow space
between them and a key 21 having the wedge-shaped ends 23 is then forced into
position between these ribs so as to firmly lock the sections together as indicated in
Figs. 1, 2 and 12. Instead, however, of arranging these keys upon the interior of
the sections, although I consider that the preferable form, I may provide the
radiator loops or sections with the projections 25 upon its sides, upon which
the inclined lugs 19 are located. These lugs may be either upon the outside of
the projections, as shown in Figs. 7 and 9, or upon the inside of the projection as
shown in Figs. 6 and 10 and in this instance the key 21 will be provided with the
inclined lugs 23 adapted to engage the lugs 19 upon the said projections 25, as
shown in Figs. 6, 7, 9, and 10; or I may provide the sections with the slotted
projections 25, as shown in Figs. 3 and 13, these projections lapping about each
other when the sections are in position, as shown in said figures, and a key 21 in
this instance being provided with inclined surfaces, and being driven through the
slots in said projections, as shown in Fig. 3.
Where the radiator sections are provided with the joints or elbows both at the
top and bottom, as shown in Figs. 1 and 2, the keys may be used also both at
the top and bottom of the sections. Where the elbows are provided only at the
bottom of the sections I may provide at the top the overlapping lugs 31, as shown
in Figs. 3, 4, 13, and 14, and provide the pins 32 for locking said projections
together.
The coupling 15 when used may be formed of a different material from the
sections themselves, or of the same material, and I consider that lead, copper or
some other soft metal would be desirable for this purpose.
While I have shown
this coupling having its opposite ends of different form, it will be understood that I
prefer to use in any radiator a coupling the ends of which are alike, but any one of
the various forms shown or any other suitable form may be used.
It will be seen that this radiator is very simple in construction and that the
sections may be put together without requiring any fitting, just as they are taken
from the sand in casting. The inclined or wedge form of the clamps permits of
more or less inequality in the castings and the ordinary packing that is used in the
sections insures a tight joint without any special fitting of the parts. The sections
are preferably firmly clamped together by means of a vice or other clamping device
and after they are thus clamped together the clamps between the sections are put
in place so as to hold them firmly in such position.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
1. The combination, with the radiator sections provided with the elbows or joint
sections adapted to engage each other and form a slip joint, and provided also with
inclined lugs, of the locking keys provided with inclined surfaces adapted to engage
the lugs on the sections and draw said sections together and hold them in their
locked position, substantially as and for the purpose set forth.
2. The combination, with the radiator loop sections provided with the joint
sections adapted to engage each other and form a slip joint, of the lugs 19 arranged
between the loops at each side of the section, and the keys provided with heads

page_text: having inclined surfaces adapted to be arranged between said sections and to
engage said lngs and thereby draw and lock said sections together, substantially as
and for the purpose set forth.
3. The combination, with the loop sections provided with the slip joints, consisting
of the shoulder projections and corresponding recesses and with a suitable packing
therein, said sections being provided also with the inclined Ings, of the locking keys
provided also with the inclined lugs and adapted to engage the lugs on said sections
and thereby draw said sections together and lock them, substantially as described.
