I JOHN JEFFREYS Heating Horticultural & Ventilating Engineer 10 Great Queen
Street Westminster do hereby declare the nature of this invention to be as follows :-
This Invention consists of an arrangement in cast iron or other suitable material
constructed to contain Steam or Hot Water for heating buildings, made as described
below.
The Radiator to be used with Hot Water is formed with a top and bottom box, of
any convenient length and width, connected together by double tubes or loops,
lozenge shaped in section, cast hollow to allow the water to circulate freely between
the top and bottom boxes & connected at each end to the latter with a WI Bolt
screwed into the top and bottom of each loop & passing completely through the boxes
and secured with a nut on the outside. A hollow pillar is cast on the inside of the
boxes in the centre of each loop surrounded by a square rebated aperture to receive
the end of the loop and the joint is made between the two with a flat piece of
indiarubber fitting tightly into the rebate and completely covering the aperture & the
top of the pillar previously described with hole in the centre for the holt to pass
through and two irregular shaped holes on either side to admit the water to the loops.
The bolt is passed through the central hole in the Indiarubber flange and the hole in
the pillar beneath and tightly screwed up from the outside of the box and the joint
made watertight.
Any number of loops may be connected to the boxes in this manner which may be
made to receive one, two, three, or more loops parallel to each other by which means
a large quantity of heat may be localized.
A Cast Iron Grating with molded edge is usually fixed to the upper side of the top box
to cover the heads of the bolts.
When the Radiator is used for Steam, the top box is omitted and the ends of the
loops are hermetically sealed with a cast iron cap & covered by a molded grating as
before.

page_text: I JOHN JEFFREYS 10 Great Queen Street Westminster London Heating, Horticultural
& Ventilating Engineer 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 consists of an arrangement in cast iron or other suitable material
constructed to contain Steam or Hot Water for heating buildings made as described
below.
The Radiator to be used with hot water is formed with a top & bottom box of any
convenient length & width, connected together by double tubes or loops, lozenge
shaped in section, cast hollow to allow the water to circulate freely between the top
and bottom boxes, and connected at each end to the latter with a Wrought
Iron Bolt screwed into the top and bottom of each loop & passing completely through
the boxes and secured with a nut on the outside. A hollow pillar is cast on the inside
of the boxes in the centre of each loop surrounded by a squaro rebated aperture to
receive the end of the loop, and the joint is made between the two with a flat piece of
indiarubber fitting tightly into the rebate, and completely covering the aperture and
the top of the pillar previously described, with hole in centre for the bolt to pass
through, and two irregular shaped holes, on oither side to admit the water to the loops.
The bolt is passed through the central hole in the Indiarubber flange and the hole in
the pillar beneath, and tightly screwed up from the outside of the box and the joint
made watertight.
Any number of loops may be connected to the boxes in this manner,
which may be
made to receive one, two, three, or more loops parallel to each other by which means a
large quantity of heat may be localized.
A Cast Iron Grating with molded edge is usually fixed to the upper side of the top
box, to cover the heads of the bolts.
When the Radiator is to be used for Steam the top box is omitted and the ends of
the loops are hermetically sealed with Cast Iron caps & covered by a molded grating
; as before.

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
1st. The special arrangement of the joint between the boxes and the loops, particularly
in the novelty of the Cast Iron Pillar I on drawings, which in addition to its value in
making the joint, serves the double purpose of holding the loops upright independently
of the top box which in the Steam Radiators is dispensed with altogether.
2nd. The arrangement of loose caps for expansion on the top ends of the loops
when used for Steam.
