Improvement in the Ventilation of Public and Private Buildings,
Sewers, and other Structures by Compressed Air, Purified or
otherwise, and in the Means for Effecting the same.
I JOHN HORROCKS of 25 Saunders Street Southport in the County of Lancaster
Engineer do hereby declare the nature of this invention to be as follows:-
To consist of a steam engin or other motive power and connected therewith shall
be an air pump or fan of sufficient constructive strength to force the air through a
range of pipes (purifiers, or otherwise) into an airholder similar to a gasholder and
thence through other needful ranges of pipes to dwelling houses public buildings &c.
in which may be placed other purifiers and coolers or may be warmed or rarefied―
when the air may be distributed at pleasure in any building by means of pipes which
shall be perforated with small holes and covered with woolen cloth or other suitable
material so that the air entering a room shall be of a gentle flow.
The compressed air may also be applied to ventilating sewers in sections by turning
on the air at one end of a section, and thus forceing the sewage gas out at the other
end of section into a stack or shaft, or pillar, which can be of any elevation and
wherein the foul air may be deodorized by charcoal or any other material most adapted
and then finaly discharged. The main object of this invention is that a building in
the city of London may be ventilated by country air.

I JOHN HORROCKS of 25 Saunders Street Southport in the County of Lancaster
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 :-
I utilise an Engine or some suitable source of motive power to compress Air to a 5
slight extent preferably to a pressure of about 2 or 3 pounds per square inch above
atmospheric pressure, the compression being effected by either an air pump or a
Blower or Fan. In the accompanying drawings Fig. I. shews the Engine A and
Compressor B. C are the delivery pipes which convey the air forward to the purifier
or washer D. Fig. II. containing water through which the air must pass from the
perforated false bottom E. or it may be from holes in a range of pipes laid at the
bottom of the tank.
Fig. III shews a form of Heater I employ in cold weather to warm the air before
it is distributed into rooms or Public Buildings for ventilating purposes. It is simply
a furnace F. within which is fixed a vessel G. with cross or vertical fire tubes H.
By means of the damper I and doors K the fire may be regulated and if desired
caused to burn very slowly. The compressed air is conveyed to the Vessel G by the
pipe C' and from the Vessel to the distributing pipes by the pipe C". These latter
pipes are preferably covered with non-conducting composition.
Fig. IV represents a longitudinal and cross section of a distributing pipe. It is
covered with felt or porous cloth for the double purpose of retaining the temperature
of the air within and of causing a checked or gentle flow of the issuing air. In some cases
I prefer to make tapered holes in the pipes as shewn at L or they may be parallel as
at M. Fig. V shews the general arrangement of my apparatus. A and B are as
before the Engine and Compressor, D is the purifier, N is a Holder for storage
purposes weighted and hydraulic sealed to suit the pressure used. From this Holder
the air can be sent by means of the branches O and O' and valves P and P₁ either
through the Heater F previously described or through cooler R which is arranged in
any convenient way for exposing a large surface of air to the action of ice or of
brine cooled in a refrigerator.
When neither the Heater nor Cooler are required the air can be passed through
either without the fire or the cooling medium being in operation. The pipes
unite into one pipe C leading to the distributors.
Another portion of my invention is the application of compressed air to the air
flushing or ventilating of sewers. The air being turned in at one end of a section
of a sewer forces the foul gas out at the other end into a stack or pillar which can be
elevation and wherin the foul air may be deodorized and discharged.

page_text: Having now particularly described and ascertained the nature of my said invention
and the manner in which the same is to be performed I declare that I do not limit
my invention to the precise methods or apparatus herein described and shewn in the
accompanying drawings, but what I claim is :-
.
I. Ventilating Public or Private Buildings, Offices etc., by air which has been
compressed as hereinbefore described and which has been conveyed in the said
compressed state from the compressing station to the Buildings to be Ventilated
substantially as hereinbefore described.
II. The use of the Hydraulic Purifier D in connection with a Ventilating System
as described in Claim I substantially as and for the purposes hereinbefore described.
III. The use of the Heater Fig. III and the cooler R Fig. V in connection with
such a Ventilating System substantially as and for the purposes hereinbefore
described.
IV. The arrangement of alternative services through either the Heater or Cooler
substantially as and for the purpose hereinbefore described.
V. Covering the distributing pipes and their outlet holes with felt or porous cloth
substantially as and for the purpose herein before described.
VI. The use of a telescopic Holder to store and regulate the pressure of air
compressed as hereinbefore described for Ventilating purposes.
VII. The application of slightly compressed air to the Ventilating of Sewers,
substantially as hereinbefore described.
