Year: 1872

page_text: LETTERS PATENT to William Thomas Thompson, of 85, Gracechurch
Street, in the City of London, for the Invention of "AN IMPROVED
VENTILATING, DISINFECTING, AND DEODORIZING APPARATUS.
PROVISIONAL SPECIFICATION left by the said William Thomas
Thompson at the Office of the Commissioners of Patents, with his
Petition, on the 23rd July 1872.
I, WILLIAM THOMAS THOMPSON, of 85, Gracechurch Street, in the
City of London, do hereby declare the nature of the said Invention for
"AN IMPROVED VENTILATING, DISINFECTING, AND DEODORIZING APPARATUS," to
be as follows:-
This Invention consists in constructing an apparatus for ventilating,
disinfecting, and deodorising purposes, applicable to private houses,
public buildings, vehicles, and other places, and the following is au
example of my said Invention:-I form a box of metal or other suit-
able material, the back of which I make higher than the sides and front;
and in the said back I cut a hole nearly the whole length of the same.

made of the same material as the box). This fan is made so as to
revolve by the action of air thereon.
This done I proceed as follows:-After having put the disinfecting
material in the aforesaid box on a sponge or otherwise, the apparatus is
fixed in such a way that the air shall act upon the aforesaid fan, and
cause it to revolve, the effect of which will be to introduce fresh air into
the apartment or other place where it is fixed, and at the same time
distribute the disinfectant that is in the aforesaid box, and also scent, if
it is desired to scent the apartment.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Thomas Thompson in the Great Seal
Patent Office on the 23rd January 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
THOMAS THOMPSON, of 85, Gracechurch Street, in the City of London,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of July, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Thomas Thompson, Her special
licence that I, the said William Thomas Thompson, my executors, admi-
nistrators, and assigns, or such others as I, the said William Thomas
Thompson, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "AN IMPROVED VENTILATING, DISINFECTING, AND DEODORISING Apparatus,”
upon the condition (amongst others) that I, the said William Thomas
Thompson, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said William Thomas Thompson, do
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :-
:
This Invention relates to improved apparatus adapted for ventilating,
disinfecting, and deodorising vehicles, also private houses, public build-
ings, and other places in a simple and efficient manner, and consists in
constructing the same in the following manner:-I take an ordinary:
rotating fan of proportionate diameter to the purpose to which it is
intended to be applied. This fan I place in a circular rim of metal
with plates respectively affixed to the edges of the said rim. The inner-
most plate is provided with two upright tubes of metal fixed to the said
plate these tubes have slits or perforations made therein, and the
bottom of each tube is closed and the upper end left open. In each of
these tubes I place any deodorising or disinfecting material, and if
desirable I place a sponge in each of the said tubes, and saturate the
said sponge with scent.
The apparatus thus made is fitted by its rim in a hole made in any
suitable part of a vehicle or building.
Now suppose the aforesaid plate with its tubes to be fixed to the
inside of a vehicle or building, the effect will be as follows:-As the
fan rotates the air being set in motion will be thrown off in a tangent,
and entering the slits in the aforesaid tubes will distribute in minute
particles the deodorising or disinfecting material or scent, and thus
purify the air within the vehicle or building.
And in order to explain my said Invention more in detail, I will now
proceed to describe the means by which it may be effected, reference
being had to the illustrative Sheet of Drawings accompanying these.
Presents, and to the numeral figures and letters of reference marked.
thercon respectively as follows:-
DESCRIPTION OF THE DRAWING.

page_text: A marks a rim of metal of the same width or nearly so as the thick-
ness of the panel or woodwork into which it is to be fitted, a hole being
made therein for that purpose, take, for example, a vehicle or door or
partition of a building; B is a flange or ring of metal screwed to the
outside of a vehicle for holding the rim A in position; C is a bar
fixed by its ends to B for supporting the pivot a of the fan C¹; D is a
thin plate of metal with tubes of metal E fixed thereto. These tubes
are closed at their lower ends, and have slits 6, or they may be per-
forations made therein for, the admission of air thereinto as the fan C¹
rotates. The plate D is fixed by screws c to the inside of a vehicle or
building, or any of the rooms thereof. G marks a portion of the panel
of a carriage or the woodwork of a partition or door of a building. The
tubes E are intended to contain a deodorising or disinfecting material or
a sponge saturated with scent, so that the external air causing the fan to
rotate enters the vehicle or building, and in so doing enters the slits or
perforations b in the tubes E, and expels the deodorising or disinfecting
material or scent in minute particles, and thus purifies or scents the air that
is within the vehicle, or building, room, or other place as may be desired.
Having now fully described and set forth the nature and object of
my said Invention for "An Improved Ventilating, Disinfecting, and
Deodorising Apparatus," together with the means by which it may be
effected, I would remark in conclusion that I hereby declare my Inven-
tion to consist in, and I claim, combining a fan ventilator with vessels
containing deodorising or disinfecting material or scent constituting
improved apparatus by the use of which the air as it passes through the
openings in the fan and also the tubes shall expel the deodorising
material or scent contained therein, and impregnate the air that is
within the vehicle or building to which the improved apparatus is
applied, and by these means effectually purify the air therein, as above
stated and represented by the Drawing.
In witness whereof, I, the said William Thomas Thompson, have
hereunto set my hand and seal, this Twenty-second day of January,
in the year of our Lord One thousand eight hundred and seventy-
three
W. T. THOMPSON. (L.S.)
