IMPROVEMENTS IN APPARATUS FOR VENTILATING AND WARMING ROOMS
Year: 1884

page_text: I WILLIAM HENRY STEPHENSON of No 67 Ainsworth Street, Blackburn in the
County of Lancaster Doctor of Medicine do hereby declare the nature of my said
invention for "IMPROVEMENTS IN APPARATUS FOR VENTILATING AND WARMING
ROOMS" to be as follows:-
For the purpose of ventilating and supplying pure warmed air to rooms or
buildings I employ concentric pipes or tubes-within the mouth of the inner tube
is a burning gas jet this causes an indraught or intake of foul air, which is
discharged outside the building, the air discharged must be replaced, and the intake
of fresh air is by way of the anmular space between the inner and outer tubes-the
supply of fresh air is thus warmed by contact with the inner hot pipe-In some
cases the concentric pipes are curved or coiled so as to increase circulation and
draught but in all instances by means of enclosing case or by variation in lengths
of the discharge and intake pipes the air for supply of the gas jet or jets receive its
or their supply of air from a source distinct and apart from the pure warmed air
introduced by the outer concentric pipe or pipes.

page_text: I WILLIAM HENRY STEPHENSON, of N° 67 Ainsworth Street, Blackburn, in the
County of Lancaster, Doctor of Medicine, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN APPARATUS FOR VENTILATING, AND WARMING
ROOMS," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
For the purpose of ventilating, and supplying pure warmed air to rooms, or
buildings, I employ concentric pipes or tubes, within the mouth of the inner tube,
is a burning gas jet, or oil flame, which causes an indraught or intake of air, which
is discharged outside the building, the air discharged must be replaced, and the
intake of fresh air is by way of the annular space between the inner and outer
tubes, the supply of fresh air, is thus warmed by contact with the concentric or
hot pipe.
Such being the nature and object of my said invention, the following is a complete
description of same, reference being had, to the accompanying drawings, forming a
part of-this-specification, in which :-
Fig. 1 is a front elevation, of an improved apparatus constructed according to this
my invention.
Fig. 2 is a sectional end elevation taken on line A. B of Fig. 1.
At 1 and 2 are concentric tubes contained within a casing 3, and any number
or order of arrangement of such tubes may be used, according to the quantity of
heated air required-At 4 is a gas or oil flame, for purpose of warming the apparatus,
thereby ensuring the necessary circulation of air, the heat in the tube 1 will pass by
the connecting pipes 5 to the annular spaces 6, and out by way of the tube 7 whilst
the air to be warned will enter at 8, and be diverted downwards, by the casing or
passage way 9, so as to circulate amongst, and by way of the concentric pipes 2, 10
and 11, to and out through the opening 12, to the building to be ventilated, and
warmed, the annular spaces 6, in pipes 10, 11, are closed at top and bottom-The
opening for exit of warmed air to the room, may consist of ornamental fret or trellis
work 12, or the cover 13 may be perforated, for exit of the warmed air-There inay
be a burner 4 and a door 14 at each end of the apparatus, at 15 is a drawer or tray
containing water for evaporation.
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
1. The general construction, and arrangement of apparatus, for purposes herein
set forth, and as illustrated by the drawings annexed.
2. The concentric tubes, or tubes one within the other, in combination with a gas
or other flame, as described and for purpose herein set forth.
