Complete Specification Left, 8th June, 1893-Accepted, 19th Aug., 1893
PROVISIONAL SPECIFICATION.
Improved Means or Apparatus for Ventilating.
We, JAMES EVANS of Cross Street, Blackfriars Street, Manufacturer and
EDWIN BREADNER of 134 Deansgate, Commission Agent, both of Manchester
in the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to provide in a compact and efficient form for
work, a machine by which ventilation, combined if desired with the humidifying
warming, cooling, disinfecting and filteration of the air passed through the
apparatus, can be more cheaply effected than heretofore.
We accomplish this as follows:-
Within a suitable case divided into two compartments we operate two fans of
improved form, both of which are keyed to and rotated by one shaft which is driven
by a belt pulley or other suitable connection from any suitable power. One of
these two compartments forms the exhaust chamber to withdraw the vitiated air
from the place it is desired to ventilate and is suitably fitted with trunks to convey
the air to the fan and from it to the outside of the building.
The other compartment supplies the fresh air to the apartment driving it through
a chamber in which are placed suitable filters of cotton wool, carbon or other
suitable material, the air being moistened if necessary by means of a suitable
injected spray of water, disinfecting fluid, or other suitable liquid which is drawn
by means of an air-jet worked by a suitable air pump from suitable receptacles
provided in the machine. The air is warmed when desired by means of a suitable
system of steam pipes placed in this chamber or may be cooled by ice or other
suitable means in a similar manner.

COMPLETE SPECIFICATION.
Improved Means or Apparatus for Ventilating.
We, JAMES EVANS, of Cross Street, Blackfriars Street, Manufacturer and
EDWIN BREADNER, of 134 Deansgate, Commission Agent, both of Manchester,
in the County of Lancaster, 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 :-
The object of our invention is to provide in a compact and efficient form for
work, a machine by which ventilation combined if desired with the humidifying,
warming, cooling, disinfecting, and filtration of the air, passed through the
apparatus, can be more cheaply effected than heretofore.
We accomplish this as follows:-
Within a suitable case divided into two compartments we operate two fans both
being keyed to and rotated by one shaft, which is driven by a belt pulley, or other
suitable connection from any suitable power. One of these two compartments
forms the exhaust chamber to withdraw the vitiated air from the place it is desired
to ventilate and is suitably fitted with trunks to convey the air to the fan and from
it to the outside of the building.
The other compartment supplies the fresh air to the apartment driving it through
a chamber in which are placed suitable filters .of cotton wool, carbon or other

page_text: suitable material, the air being moistened or disinfected if necessary by means of a
suitable injected spray of water, disinfecting fluid, or other suitable liquid which is
drawn by means of an airjet worked by a suitable air pump from suitable receptacles
provided in the machine. The-air is warmed when desired by means of a suitable
system of steampipes placed in this chamber, or may be cooled by ice or other
suitable means in a similar manner.
In order that the foregoing may be better understood we send herewith a sheet
fof drawings, in which
Fig. 1 is a longitudinal and Fig. 2 a cross section of our apparatus.
In these figs. a and
respectively indicate the exhaust and supply fans, both
rotated by the shaft c and pulley c².
The fan a revolves in compartment d of the apparatus, drawing in the vitiated
air by trunk d and discharging it by trunk d³..
The fan revolves in compartment e drawing in fresh air by trunk then
forcing it by the passage into and through the filter f, containing, carbon, cotton
wool or other suitable material, which is moistened by the jet spray 9, actuated by
the air pump h, which forces a certain portion of the liquid contained in the
cistern out of the spray jet g at every revolution of the shaft c; the liquid con-
tained in the cistern & is varied as may be required, either iced or fresh water,
disinfecting fluid or chemical being used as needed.
.
The air after passing the filter is forced through the cylinder which can be
utilized for warming or cooling the air as may be required, the internal cylinder m
being, filled with steam in the one case and ice or refrigerating fluid in the other.
The air enters through the opening and after passing to the farther end of the
cylinder returns through the tubes m' and passes into the apartment or wherever
required through the trunk n.
The filtering material is contained in a case or drawer o which can readily be
removed by the door p.
The steam or cooling, fluid is admitted into the internal cylinder m by the tube r
and leaves it by the tube s.
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
claim is
2
The combined apparatus substantially as described and shown hereinbefore and
in the accompanying drawing for the purpose set forth..
