PROVISIONAL SPECIFICATION.
Improvements in the Construction of Radiators for Heating and
Ventilating Purposes.
We, FRANK ASHWELL, of Victoria Foundry, Sycamore Lane, Leicester, in the
County of Leicester, and DAVID MEIN NESBIT, of 14 John Street, Adelphi,
London W.C. trading as Ashwell and Nesbit, Heating and Ventilating Engineers,
do hereby declare the nature of this invention to be as follows :-
Our invention relates to improvements in heating and ventilating apparatus of
the type described in the Specification of Patent No. 926 of 1890 granted to one of
us and our object is to increase the efficiency and regulate the action of our
improved ventilating radiator.
Our invention cousists in improvements in construction and details of the
appliances described in the Specification hereinbefore referred to and in carrying
our invention into effect we build up our radiator of separate sections or loops as
therein described each section living suitable facings to form joints, and the said
joints being pulled together by one long bolt for each series of joints.
In our present invention we construct each section or loop of two upright pipes
of the desired configuration length and area; these pipes are connected to each
other by a convenient rib or ribs cast between them and each pipe-is-provided top
and bottom with facings having passages of preferably semi-circular section.
When our loops or sections are bolted together to form a radiator two long bolts at
the bottom and two long bolts at the top pass through holes cored out or bored out
to receive them and when these bolts are screwed up the whole series of loops or
sections are firmly united together in a steam or water tight manner and form
together a very convenient and offective radiator. Steam is passed through the
series and suitable connections are made for this purpose. If required we introduce
blank flanges at intervals in positions to cause the steam to follow a tortuous course
but this device is not always necessary as the steam naturally divides itself between
the different sections. Instead of steam we may and do sometimos use hot water
to heat our radiator surfaces.
Steam or water pipe and drainage connections are made as described in
Specification No. 926 of 1890, but generally the steam or hot water currents pass
up the pipes on one side of the radiator and down the pipes on the other side; this
flow of the heating currents may be modified however by blank flanges and baffle
or deflector plates when desired.
The facings between each section are preferably machined and thin joints of
asbestos or other suitable material inserted between them.
By separating the facings as herein described a continuous chamber is formed
both at the bottom and the top of each radiator. We cover the top with an
ornamental grating or grid and along the bottom chamber we arrange a hinged
flap or valve so placed that when it lies on the one side, the bottom chamber opens
to a passage or passages to the outer atmosphere and the air entering from the
outer atmosphere passes through the spaces between the pipes and ribs of the
radiator and is heated before it enters the room or building. When the hinged
flap or valve is placed in the other position the connection to the outer atmosphore
is shut off and air from the room or building passes into the radiator to be heated.
In this manner the radiator is adapted both for heating and ventilating.
The valve or flap is preferably formed as a long plate hinging from the floor or
ground lavel and enclosed in the chamber formed by extensions used to raise the
radiator from the floor or ground. Those extensions or feet are made continuous

page_text: from back to frout for this purpose and are so shaped together with the lower part
of the radiator that when the radiator is placed against a wall a chamber is formed
in which the long plate valve can act.
Openings to the outer air are formed in the wall opposite to the plate valve and
when the valve is hinged from the floor to close these openings no air can enter by
them but when the valve is hinged away from the openings air enters by them
through the radiator into the room and thence we determine whether fresh air
shall be admitted to the room or not.
When a long radiator is used having feet extension plates between the end platos,
hinged valve plates are arranged between each pair. The hinged valve plate or
plates is or are operated by a spindle passing through the end or intermediate plates
and the said spindle is operated by a convenient lever or levers moving over a
quadrant marked "Open" and "Shut" at opposing ends.
The lever may be fitted with an adjusting screw to set it at any position on the
quadrant so as to regulate the opening of the air valve into the room or building
and so regulate the flow of fresh air.
It is to be understood that when the valve plate is placed. to close off the outer
atmosphere then the air of the room has free access to the space between the two
rows of pipes from below so that it may pass in below and out above the radiator in
a warmed condition.
We preferably construct our upright pipos of a section forming an irregular
polygon having six external flat sides and so we greatly increase the surface
exposed, by the said pipes for heating both by radiation, convection and conduction.

COMPLETE SPECIFICATION.
Improvements in the Construction of Radiators for Heating and
Ventilating Purposes.
Wo, FRANK ASHWELL, of Victoria Foundry, Sycamore Lane, Leicester, in the
County of Leicester, and DAVID MEIN NESBIT, of 14 John Street, Adelphi,
London W.C. trading as Ashwell and Nesbit, Heating and Ventilating 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 :-
Our invention relates to improvements in heating and ventilating apparatus of
the type described in the Specification of Patent No. 926 of 1890 granted to one
of us, and our object is to increase the efficiency and regulate the action of our
improved ventilating radiator.
Our invention consists in improvements in construction and details of the
appliances described in the Specification heroinbefore referred to and in carrying
our invention into effect we build up our radiator of separate sections or loops as
thorein described each section having suitable facings to form joints, and the said
joints being pulled together by one long bolt for each series of joints.
In the accompanying sheet of explanatory drawings,
Figure 1 is a perspective and partly sectional elevation of our improved heating,
and ventilating radiator.
Figure 2 is a sectional elevation through the coils, and
Figure 3 is a sectional plan of the same.
Figure 4 is a front elevation of a portion of our coils showing the end caps.
In our present invention we construct each section or loop of two upright
pipes A B of the desired configuration, length and area; these pipes are connected
to each other by a convenient, rib or ribs E cast between them, and each pipe is

page_text: provided, top and bottom, with facings having passages ab of preferably semi-
circular section. When our loops or sections are bolted together to form a
radiator two long bolts at the bottom H HI' and two long bolts at the top K K
pass through holes cored out or hored out to receive them, and when these bolts
are screwed up the wholo series of loops or sections are firmly united together in a
steam or water tight manner and form together a very convenient and effective
radiator as shown at Figure 1. Steam is passed through the series and suitablo
connections are made for this purpose.
If required we introduce blank flanges at intervals in positions to cause the steam
‣ to follow a tortuous course but this device is not always necessary, as the steam
naturally divides itself between the different sections.
Instead of steam we may and do sometimes usa hot water to heat our radiator
surfaces.
Steam or water pipe and drainage connections are made as described in Specifi-
cation No. 926 of 1890, but generally the steam or hot water currents pass up the
pipes on one side A A' of the radiator and down the pipes on the other side B B';
this flow of the heating currents inny bo modified however by blank flanges and
baffle or deflector plates when desired.
The facings LL' between each section are preferably machined and thin joints
of asbestos or other suitable material inserted between them.
By separating the facings as herein described a continuous chambor is formed both
at the bottom and the top of each radiator. We cover the top with an ornamental
grating or grid C and along the bottom chamber wo arrange a hinged flap or
valve D so placed that when it lies on the one side, the bottom chamber opens to a
passage or passages to the outer atmosphere and the air entering from the outer
atmosphere F passes through the spaces between the pipes A B and ribs Ę of the
radiator and is heated before it enters the room or building through the upper
grid C. When the hinged flap or valve D is placed in the other position the
connection to the outer atmosphero is shut off and air from the room or building
at G passes into the radiator to be heated.
In this manner the radiator is adapted both for heating and ventilating.
The valve or flap D is proferably formed as a long plate hinging from the floor
or ground level or pivoting upon bearings O carried upon the floor or formed upon
the end legs M M and enclosed in the chamber formed by extensions used to raise
the radiator from the floor or ground.
These extensions or feet M M' are made continuous from back to front for this
purpose and are so shaped together with the lower part of the radiator that when
the radiator is placed against a wall, a chamber is formed in which the long plate
valve D can act. Openings to the outer air are formed in the wall opposite to the
plate valve, and when the valve is hinged from the floor or turned to close these
openings no air can enter by them, but when the valve is hinged away from the
openings, air enters by them through the radiator into the room, and we thence
determine whether fresh air shall be admitted to the room or not.
When a long radiator is used having feet extension plates M between the end
plates, hinged valve plates are arranged between each pair of plates or feet. The
hinged valve plate or plates is or are operated by a spindle passing through
the end of intermediate plates and the said spindle is operated by a convenient
lever or lovers moving over a quadrant marked “ Open” and “Shut” at opposing
ends.
The lever may be fitted with an adjusting screw to set it at any position on the
quadrant so as to regulate the opening of the air valve into the room or building
and so regulate the flow of fresh air.
It is to be understood that when the valvo plate D is placed to close off the outer
atmosphere F then the air of the room G has free access to the space between the
two rows of pipes A B from below so that it may pass in below and out above the
radiator through C in a warmed condition.
We preferably construct our upright pipes of a section forming an irregular

page_text: polygon having six external flat sides as shown at Figure 3, and so we greatly
increase the surface exposed by the said pipes for heating both by radiation,
convection and conduction.
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 5
claim is :-
1. The construction and arrangement of heating and ventilating coils in which a
bottom valve or pivoted or hinged inlet plate is employed to regulate the supply of
air, substantially as hereinbefore described and as illustrated in the accompanying
drawings.
2. In a heating and ventilating radiator, the construction of coils in segments
having two separate channels or pipes such as A B connected together by means of
a central web or plate such as E, substantially as and for the purposes hereinbefore
described and as illustrated in the accompanying drawings.
3. The heating and ventilating arrangements hereinbefore described and as 1
illustrated in the accompanying drawings.
Dated this 30th day of October 1803.
