Improvements in Apparatus for Warming and Ventilating
Buildings.
I, RICHARD OAKLEY of 124 High Holborn, Ventilating Electrical and Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
:-
The paramount importance of warming the fresh air admitted for ventilating
purposes in winter time has long been recognised, and various attempts have been
made to accomplish the end. Where these provisions are made whilst a building is
in course of construction, the object desired is not difficult of attainment, either in
connection with the hot-water apparatus, or by gas or other ventilating stoves, as in
the latter cases the necessary flues for carrying off the products of combustion can be
constructed in the walls, but for buildings already erected there has always been great
difficulty in making such provision. Where gas has been employed as the heating
agent, the inlet ventilator, with its gas furnace, has always hitherto been fixed inside
the building. The products of combustion have consequently either been permitted
to enter into the apartment, or an unsightly and complicated system of metal fine-
pipes has had to be arranged at great expense for conducting these products outside ;
but the unsightliness and cost are by no means the measure of the evil. In the vast
majority of cases, and especially in cold weather, condensation takes place in these
flue pipes, and the heavy gases choke the flue, extinguishing the flame at the burner
followed by an escape of gas at once dangerous and disagreeable. The object of the
present invention is to keep the whole of the gas-heating apparatus outside the building,
and it is arranged so that by no possibility either the gas itself or the products of gas
combustion can enter the building.
The apparatus consists of a casing traversed by a tube or tubes opening at one end
to the air and at the other to the inlet to the building. A gas burner or burners are
placed at the bottom of the casing and the products of combustion surround and heat
the air tubes. The casing is provided with an opening for the admission of air to
support combustion and also with an opening for the escape of the products of
combustion. The latter by preference leads to a short flue provided with a cowl to
prevent back draught. The whole of this apparatus is placed outside the building.

Improvements in Apparatus for Warming and Ventilating
Buildings.
I, RICHARD OAKLEY Ventilating Engineer 124 High Holborn 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 my invention is to provide a simple and effectual means of heating incoming
air for ventilating purposes in winter time by means of gas and for carrying off the 5
products of gas combustion in such a way as to avoid risk of explosion in the
building on the one hand and to render impossible the admixture of the said products
with the incoming air on the other and to keep the whole of the heating apparatus
outside the building. And my invention can also run as an ordinary cold air inlet in
warmer weather.
The apparatus consists of a casing of metal A traversed by a tube or tubes B
opening at one end to the air C and at the other to the inlet to the building D. A gas
burner E or burners is placed at the bottom of the casing and the products of com-
bustion surround and heat the air tubes. The casing is provided with an opening F
for the admission of air to support combustion and also with an opening G for the escape
of the products of combustion. The latter by preference leads to a short flue H
furnished with a cowl to prevent back draught.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is
1st. An apparatus which shall optionally serve as a cold or warm air inlet.
2nd. That the whole of the Apparatus is external to the building.
3rd. That it is portable and can be removed at pleasure in a completo state.
Doted this Thirteenth day of August 1888.
