JAMES FREDERICK BENNETT, 42, Woodstock Road, Sheffield, Engineer, and
HEDLEY STANLEY MOORWOOD, of Harleston Iron Works, Sheffield, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in Radiators & consists in making a
Radiator in such a manner that we have at the same time a light, efficient and
easily made apparatus.
(1) We have a hollow top having large holes at the underside and smaller
ones at the upper face.
The base of the Radiator has also corresponding holes.
(2) We make tubes either ornamental or plain and in the case of ornamental
drawn or stamped tubes we roll or press out the ends so as to form a plain smooth
tube, these tubes are then placed in the large holes, and expanded in by means
of a tube expander or other suitable means. Large holes or appertures may be left
in the covers so as to allow the expander to be placed inside, the expanded mandril
in this case being worked round by passing it through the small hole which is con-
centric with larger one. Of course we may have the base & upper part in two
halves the parts to be fastened together after the tubes are expanded in. (3) The
small holes thus left open are now plugged up or a thimble or cap shaped tube is
expanded in, this thimble or cap may be of any convenient length, thus it might
dip down deep into the space giving thus additional displacement of water. Should
we wish to make our Radiator ventilating we pass tubes (either plain or figured)
right through the large tubes expanding same in at the little holes.
Thus we get
a watertight vessel & have a central draught up the tubes.
(4) As a further improvement we place a bottom on the base, which may be
in communication with the outside air, thus bringing a clear fresh atmosphere,
or we may place a Bunsen or other gas or oil burner in such a manner that the
heat passes through one or more tubes. The tubes may have a cover at top to take
away the fumes or coal or charcoal may be used to heat the apparatus.
Thus we get a tubular boiler without a separate boiler or we may dispense with
heating apparatus and connect up with a boiler in the ordinary manner.

We, JAMES FREDERICK BENNETT, 42, Woodstock Road, and HEDLEY STANLEY
MOORWOOD, of the Harleston Iron Works, both of Sheffield, in the County of York,
Engineers, do hereby declare the nature of our said invention and in what manner

the following statement:-
-
Our invention relates to improvements in radiators and consists in making a
radiator in such a manner that we have at the same time a light, efficient and
easily made apparatus.
The nature of our invention will be better understood on reference to the
accompanying sheet of drawings_ in which,
Fig. 1, is a side elevation partly in section of our improved radiator.
Fig. 2, being an end elevation of the same, and,
Fig. 3, a plan partly in section.
Fig. 4, is a partial elevation of a modification of our radiator adapted for
ventilating as well as for heating.
Fig. 5 being a plan of the same.
Fig. 6, is an elevation partly in section of a further modification of our improved
radiator adapted as a self contained heating stove to be used either with solid or
gaseous fuel.
Fig. 7, being a vertical section taken through one of the fire tubes.
Figs. 8 & 9, are enlarged views of the ends of our improved external radiator
tube, shewing one end of the tube rolled out or expanded ready for use.
The same letters refer to similar parts throughout the several views.
We construct a hollow top or entablature, a, having large holes, b, at the under-
side and smaller holes, c, at the upper face. The hollow base or plinth, d, of the
radiator has corresponding holes, b¹, c¹.
We make tubes, e, either ornamental or plain, and in the case of ornamental
drawn or stamped tubes, we roll or press out the ends so as to form a plain smooth
surface as shewn in Figs. 8 & 9, these tubes are then placed in the large holes_b, b',
and expanded in by means of a tube expander or other suitable means. Large
holes or apertures with covers, f, f¹, may be left in the ends of the top or
entablature, «, and likewise in the base or plinth, d, so as to allow the expander to
be placed inside. The expander mandril in this case being worked round by
passing it through one of the small holes, c, c¹, which is concentric with the large
holes, b, b¹.
The small holes, c, c¹, are then plugged up, or a thimble or cap shaped tube, g,
is expanded into them. This thimble or cap, g, may be made of any convenient
length, thus it might dip down deep into the space, thereby giving additional dis-
placement of water, or a longitudinal displacer may be employed when the radiator
is not used as a ventilator such longitudinal displacer extending from end to end
of the hollow top a, or the hollow base, d.
Should we wish to make our radiator ventilating, we pass tubes, h, either plain
or ornamental right through the large tubes, e, (as shewn in Fig. 4,) and expand
them into the small holes, c, c¹, previously mentioned, thus we get a water tight
vessel having a central draught up the tubes.
As a further modification we place a bottom or pedestal, i, under the base or
plinth, d, which in the case of a ventilating stove may be utilized as an air chamber
for communicating with the outside air, thus bringing a clear fresh atmosphere
into the room, or we may place a Bunsen or other gas or oil burner, j, in such
a manner that the heat passes through one or more of the tubes, h. These tubes
may have a cover, k, at the top to which may be connected a pipe, 7, to take away
the fumes. In some cases coal or charcoal may be used to heat the apparatus. We
thus obtain a tubular boiler without a separate boiler, or we may dispense with
heating apparatus and connect up with an independent boiler in the ordinary
manner.
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 radiatore the pantinalen m 1

page_text: expander may be introduced and operated during the process of expanding-the-
circulating and radiating tubes into the holes provided for their reception in the
hollow top or entablature (a), and in the hollow base or plinth, (d), in the manner
and for the purposes substantially as herein described and illustrated in the
accompanying sheet of drawings.
2. In combination with the particular method of construction herein set forth,
the application of plain, or fluted, or twisted, or otherwise ornamented wrought or
drawn metallic tubes (as distinguished from cast metal tubes) the ends of such
wrought or drawn metallic tubes being rolled or pressed out so as to form a plain
smooth surface to allow of their being expanded into the holes provided for their
reception in the manner and for the purposes substantially as herein described and
illustrated in the accompanying sheet of drawings.
3. In radiators, the application of fluted, or twisted, or otherwise ornamented
wrought or drawn metallic tubes (as distinguished from cast metal tubes) the
ends of such wrought or drawn metallic tubes being rolled or pressed out so as to
form a plain smooth surface to allow of their being expanded into the holes pro-
vided for their reception in the manner and for the purposes substantially as herein
described and illustrated in the accompanying sheet of drawings.
