COMPLETE SPECIFICATION.
Improvements in Apparatus for Heating Air.
I, EDWARD TAYLOR, of 80, Lower Hillgate, Stockport, in the County of Chester,
Laundry 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 relates to the construction of improved apparatus for heating
air by the utilization of the waste heat in boiler or other flues, for warming rooms
or for drying clothes, and the like.
The apparatus consists principally of iron boxes built in the walls at the ends of
the flue and a series of pipes connecting them together, through the open ends of
which the cold air is drawn in by a fan or otherwise and the said pipes being
heated by the waste gases from the boiler or other fire, the air in passing through
the said pipes becomes heated also.
The boxes are all open to the air at one end and at the other end they are
enclosed and connected together so that the air which has been warmed in passing
through the pipes can be conveyed direct to the place where it is to be used, a
fan or other means being employed to induce a current.
The method of carrying my invention into practical effect will be readily under-
stood on reference to the sheet of drawings hereunto annexed and the following
explanation thereof.
Fig. 1 on the drawing is an elevation, Fig. 2 a transverse section, and Fig. 3 a
plan view showing the application of my invention to the end flue of an ordinary
steam-boiler, A being part of the boiler and B the brick work forming the flues.
Fig. 4 are end elevations on a larger scale of the box with and without cover
plate, and Fig. 5 longitudinal sections showing details of the air tubes and end
boxes.
a are the air tubes, b is the box at the cold air inlet end and b¹ the box at the
warm air outlet end leading by the passage d to the drying room.
The tubes a are not a fixture in the boxes b. and 6¹ but are so connected to them (as
seen at Fig. 5) that they are free to expand and contract, the connection being
made by means of a stuffing box c and cover plate c¹, at each end charged with
asbestos or other suitable flexible material which will make an air-tight joint so
that the tubes a can expand and contract, and the soot and foul air from the flue
cannot be drawn into the warm air tubes.
The boxes and b¹ are made of such a diameter internally that a socket or
coupling used for joining two tubes can be passed through them, because when
there is not much room at the flue, the tubes a would have to be in short lengths as
it would be necessary to take them out occasionally to clean them, and also where
more than one boiler is used the tubes would of course be longer than they are
shown on the drawing and would be too long for ease of handling and also for
carriage.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
The improved apparatus constructed substantially as hereinbefore described and
illustrated by the annexed drawings for utilizing the waste heat from boiler or
other flues for warming rooms or for drying clothes and the like.
