London, W., and JOSEPH NELSON RUSSELL, Engineer Digby House The Mall
Hammersmith London, W., do hereby declare the nature of this invention to be as
follows:-
Each loop of a radiator will have bosses cast on each side at the upper end and
in the length of the radiator. These bosses, with a hole in each, to be faced on
both sides of the loop (if needed) so as to be fairly parallel or true with the loop
bosses on each side. Between each loop in the spaces between the bosses a copper
brass or other elastic washer having conical faces on both sides and made in various
widths so as to just fill the intervening spaces are to be placed. A bolt the length
to suit the number of loops in the radiator but of smaller diameter than the holes
in the bosses is then passed through and nutted at each end. The conical washers
are compressed by tightening the bolt and the sharp edges adapted to the faces of
the bosses on each side of the loops so as to form a perfect joint and allowing for
expansion or contraction when either hot or cold.
The central holes in the bosses on each loop, being larger than the bolt, allow
the air to pass into any loop and so to be drawn off from any of the loops by one
air tap or pipe.

Improvements in Radiators used for Heating Buildings and the like.
We, ROSSER & RUSSELL, LIMITED, Engineers and Heating Apparatus
Manufacturers, 22 Charing Cross, S.W., and Queen's Wharf, Queen's Street,
Hammersmith, London, W., and JOSEPH NELSON RUSSELL, Engineer, Digby
House, The Mall, Hammersmith, London, W., 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 the construction of radiators employed
for warming purposes with hot water, hot air or steam, though the present invention
is peculiarly applicable where hot water is used and when it is desirable to get rid
of the air promptly. Usually each "loop" or section of the radiator is more or
less independent of its fellows the upper parts of all the loops not being connected
together as they are in the present invention. By connecting them together the air
is readily collected in the top chamber thus formed and can be carried off by a
single tap or valve. The invention will be best understood by reference to the
accompanying drawings in which
Fig. 1 is a vertical section of the upper part of a radiator of four loops,
Fig. 2 being a sectional plan of the same, and Fig. 14 an end elevation.
Fig. 3 is a sectional plan of a modified construction, of the upper part of which
Fig. 4 is an elevation and Fig. 5 a vertical cross section upon the line 5-5 of

page_text: Fig. 6 is a similar view to. Fig. 2 but shows the loops arranged in a circular curve
Fig. 7 being a side view of a radiator constructed according to Fig. 6, and Fig. 8
an end or edge view of Fig. 7.
Figs. 9, 10 and 11 are sectional views showing various ways of applying the
pressure to the junction rings.
Like letters represent like parts throughout the drawings.

A are the loops and B Figs. 1, 2 and 14 the rod by which they are all con-
nected together the said rod being screwed at the ends and provided with nuts B¹
for tightening the whole up. The boss A' of each loop has a hole or passage A³
in it so that a passage from the whole of the radiators is provided, the tops of all
the radiators forming in effect a single chamber. The faces of the bosses A¹ are
trued up in any convenient manner and between each pair of contiguous bosses is
inserted a ring C of brass copper or other suitable metal or material the edges
of which are coned or sharpened so as to present a
"knife edge to the opposing
surface of the bosses against which it is pressed when the parts are screwed
together so that the "knife edge" embeds itself in the face of the boss or if the
material be sufficiently yielding presses so closely there-against accommodating
itself to any irregularities as to make a tight joint. For convenience in fitting the
parts together each ring C is provided with an extension head C which extends to
the top of each boss and thus holds the ring suspended while the bolt B is passed
through and before it is screwed up.
In the modification illustrated in Figs. 3, 4 and 5 two sets of loops A are
employed, between which is placed a box D having openings D₁ so that a through
connection is made between each pair of loops A and the box D the result being
that as the whole of the radiator loops communicate with the box D the whole
forms one common chamber from which the air may be liberated by a single cock
or valve. These radiators are connected together by bolts B exactly as in the
former case, two packing rings C being employed between each pair of loops A.
(one on each. side of the box D) instead of a single ring.
The arrangement shown in Figs. 6, 7 and 8 is the same as that shown in Figs 1, 1ª
and 2 excepting that instead of being arranged in a straight line the loops are
arranged around a curve.
In Fig. 9 is shown a means of connecting the pipe E of the radiator or hot
water boiler with one of the loops A or other part of the apparatus.
Here the interior of the pipe E is reduced at E' so as to form a bearing for the
dog F from which the bolt B extends and carries a nut upon the outside of the
loop or other portion of the apparatus, the joint being made with a packing ring C
as above described. The bolt B may be made in one piece with the dog F if the
circumstances admit of the dog being introduced into the tube E when so connected
or the bolt B may be loose in the dog F and pass through it with a head to
prevent it from being drawn out or it may be screwed into the dog after the dog
has been inserted into the tube; in the last case means may be provided if
necessary such as a notch or recess in the portion E' of the tube E to prevent the
dog from turning when the bolt B is being screwed into it.
In Fig. 10 the arrangement is substantially the same as in Fig. 9 excepting that
the bolt B instead of being concentric with the tube E passes through a lug E'
upon the tube and a lug A³ upon the loop or other portion of the apparatus.
In Fig. 11 the arrangement closely resembles that adopted in Fig. 9 excepting
that the bolt B passes through the whole length of the tube E and through the
loop or other portion of the apparatus at the other end of the tube where it bears
a nut in a manner similar to that shown in Fig. 11.
In Figs. 9, 10 and 11 the ring C instead of being provided with a head such
as C is provided with one or more peripheral extensions E³ which may be either
three or more projections or a continuous flange the object being to keep the ring
concentric with the faces with which it co-operates to make the joint as clearly
indicated in Figs. 9, 10 and 11.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. In a joint such as described the employment of a knife-edged or conical ring
such as C substantially as and for the purpose described and illustrated in the
accompanying drawings.
2. In a joint such as described the combination with a ring such as C of a head
such as C for the purpose of retaining the ring in its proper position before
the parts are tightened up substantially as described and illustrated in the accom-
panying drawings.
3. In a joint such as described the combination with a pair of loops such as A
having faced bosses such as A' of a knife-edged or conical ring such as C
substantially as and for the purpose described and illustrated in the accompanying
drawings.
4. In a radiator the combination of a number of loops such as A with passages
between so that the said loops form a substantially continuous chamber substantially
as described and illustrated in the accompanying drawings.
5. In a radiator the combination with a series of connected loops such as A of
rings such as C which allow of a tight joint being made between each two adjacent
loops and a bolt B passing through the whole of the loops and provided with nuts B¹
substantially as and for the purpose described and illustrated in Figures 1 and 2 of
the accompanying drawings."
6. In a radiator having loops such as A connected together in pairs of a box
such as D connected with each loop of each pair in such a manner as to connect the
loops and thus form substantially a common chamber at the end of the loops
substantially as described and illustrated in Figs. 3, 4 and 5 of the accompanying
drawings.

drawings.
8. In a joint such as described the combination with two loops such as A having
recessed faces and a tube such as E having end faces and a full internal diameter
throughout of a bolt B passing through the tube and loops and by which they may
be screwed together substantially as described and illustrated in Figure 11 of the
accompanying drawings.
