Year: 1877

page_text: LETTERS PATENT to William Verity and Benjamin Verity, both of 127, Regent
Street, in the County of Middlesex, for the Invention of "A VENTILATING
AND FUMIGATING APPARATUS."
Scaled the 28th August 1877, and dated the 7th June 1877.
PROVISIONAL SPECIFICATION left by the said William Verity and Bon-
jamin Verity at the Office of the Commissioners of Patents on the 7th June
1877.
WILLIAM VERITY and BENJAMIN VERITY, both of 127, Regent Street, in the
County of Middlesex. "A VENTILATING AND FUMIGATING APPARATUS."
The apparatus to be made in any suitable material or materials, and in all and
every size or shape. It is intended to be adapted for the ventilation or fumigation
(or both objects combined) of rooms or buildings. It is also suitable for other
purposes where a constant blast of air would be servicable, such as to work blow
pipes for jewellers, glass blowers, dentists, &c.
The size of the apparatus and its appurtenances to be regulated by the capacity
of such rooms or buildings proposed to be ventilated; or in the instance of the
aforesaid blow pipe service, the size of the apparatus and its appurtenances to be
regulated by the amount of power required to be given.
The whole of the aforesaid apparatus is complete in itself, and is intended to be fixed
between joists beneath flooring, or other convenient position having connection with
the external air by means of a pipe or tube through outer wall of room or building,
as aforesaid. The motive power to be hydraulic, and arrived at by the injection of
water on to the "hydraulic fly wheel" (as shewn in annexed Drawings), which
working on the same axle as the rotary fan in drum causes the latter named to
revolve, and thus draw or suck in the air which in the course of a revolution is
naturally propelled forward, causing a constant current of air to flow into the room
or building where it may be in use. This current of air may be received at will, as
the motive power is under control of a stop tap placed in water supply pipe, and
n

page_text: which can be fitted in any convenient place or position; the aforesaid current of
air may be received cool by the introduction of rough ice fumigated or scented,
according to that which is placed in small reservoir provided in out-pour tube.
By a contrivance in connection with the nearest fire-place fresh warm air may be
introduced if desired.
It is also provided that the apparatus shall form an exhauster when placed in the
upper part of room or building for the egress of the vitiated atmosphere, the fresh-
air supply, as herein-before stated, being introduced on the floor line.
The apparatus or Invention will be understood by reference to annexed Drawings
and the following description thereof.
Figure 1 is.a vertical section taken through the line E, F, looking towards N, on
sectional plans 5 & 6.
Figure 2 is a vertical section taken through the line I, J, looking towards K, on
sectional plans 5 & 6.
Figure 3 is a vertical section of hydraulic fly wheel on the line L, M, shewn in
Figure 2.
Figure 4 is a sectional elevation on the line G, H, looking towards K, on plans 5
and 6.
Figures 5 and 6 are sectional plans, as indicated.
A is a reservoir for inserting rough ice to cool the air, scent, or a disenfectant to
perfume or fumigate it (i. e. the air), as may be desired, before it is discharged
through out-pour tube B into room or building. The aforesaid reservoir not
.being an essential part of the apparatus can be dispensed with at will. C is the
.rotary, fan for propelling, the air, and is worked on the same axle and by the
hydraulic fly wheel I (shewn in Figure 2); D is the waste water pipe from hydraulic
fly wheel I, and is carried into the finely-perforated strainer E, from which it passes
in a spray or shower into inlet tube G, and is finally conveyed away by waste
pipe F. The air on entering the aforesaid inlet tube G is made to pass through
this spray or shower, and thus becomes moistened in its progress through apparatus,
but a dry atmosphere can be had with equal facility by dispensing with the aforesaid
arrangement and discharge waste water from hydraulic Hy wheel direct. H is a
waste water pipo or tube from ice reservoir A; J is a stop tap for controlling water
power, which may be fitted immediately over hydraulic fly wheel, or any other
convenient place or position in the water service.
.
Having thus described the nature of our said Invention, and in what manner the
same is to be performed, we declare that we claim,-
The general combination and arrangement of parts forming a ventilating and
fumigating apparatus, as described and shewn, for the purposes set forth..
Secondly. We claim for the use of the hydraulic fly wheel as a motive power to
'drive fotary fan, for the purposes set forth.
Thirdly. We claim for the spray or shower bath, by which the air is washed or
moistened on passing through apparatus, for the purposes set forth.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Verity, and Benjamin Verity in the Great Seal Patent Office
on the 5th September 1877..

WILLIAM VERITY and BENJAMIN VERITY, both of 127, Regent Street, in the
County of Middlesex. "A VENTILATING AND FUMIGATING APPARATUS."
The apparatus to be made in any suitable material or materials, and in all and

The whole of the aforesaid apparatus is complete in itself, and is intended to be
fixed between joists beneath flooring, or other convenient position having connection
with the external air by means of a pipe or tube through outer wall of room or
building, as aforesaid... The motive power to be bydraulic, and arrived at by the
injection of water on to the "hydraulic fly wheel" (as shown in annexed Drawings),
which working on the same axle as the rotary fans in drum causes, the latter named
to revolve, and thus draw or suck in the air which in the course of a revolution is
naturally propelled forward, causing a constant current of air to flow into the
room or building where it may be in use. This current of air may be received
at will, as the motive power is under control of a stop tap placed in water-
supply pipe, and which can be fitted in any convenient place or position; the
aforesaid current of air may be received cool by the introduction of rough ice
fumigated or scented, according to that which is placed in small reservoir provided
in outpour tube.
By a contrivance in connection with the nearest fire-place fresh warm air may be

It is also provided that the apparatus shall form an exhauster when placed in the
upper part of room or building for the egress of the vitiated atmosphere, the fresh-
air supply, as herein-before stated, being introduced on the floor line.
The apparatus or Invention will be understood by reference to annexed Drawings
and the following description thereof:-
Figure 1 is a vertical section taken through the line E, F, looking towards N, on
sectional plans 5 and 6.
Figure 2 is a vertical section taken through the line I, J, looking towards K, on
sectional plans 5 and 6.
Figure 3 is a vertical section of hydraulic fly wheel on the line L, M, shewn in
Figure 2.
Figure 4 is a sectional elevation on the line G, H, looking towards K, on plans 5
and 6.
Figures 5 and G are sectional plans, as indicated.
A is a reservoir for inserting rough ice to cool the air, scent, or a disinfectant to
perfume or fumigate it (i. e. the air), as may be desired, before it is discharged
through outpour tube B into room or building. The aforesaid reservoir not being
an essential part of the apparatus can be dispensed with at will. C, C, are the
rotary fans for propelling the air, and is worked on the same axle and by the.
hydraulic fly wheel I, shown in Figure 2; D is the waste-water pipe from hydraulic
fly wheel I, and is carried into the finely-perforated strainer E, from which it passes

convenient place or position in the water service.
Having thus described the nature of our said Invention, and in what manner
the same is to be performed, we declare that we claim,―
The general combination and arrangement of parts forming a ventilating and
fumigating apparatus, as described and shewn for the purposes set forth.
Second. We claim for the use of the hydraulic fly wheel as a motive power to
drive rotary fans, for the purposes set forth.

page_text: Thirdly. We claim for the spray or shower bath, by which the air is washed or
moistened on passing through apparatus, for the purposes set forth.
In witness whereof, we, the said William Verity and Benjamin Verity, have
hereunto set our hands and seals, this Fifth day of September, in the year
of our Lord One thousand eight hundred and seventy-seven.
