Year: 1873

page_text: LETTERS PATENT to Martin Tobin, of Leeds, in the County of York,
Gentleman, for the Invention of "AN IMPROVED MEANS OR MODE OF
VENTILATING ROOMS OR APARTMENTS AND IN THE APPARATUS EMPLOYED
THEREFOR."
Sealed the 16th September 1873, and dated the 24th March 1873.
PROVISIONAL SPECIFICATION left by the said Martin Tobin at the
Office of the Commissioners of Patents, with his Petition, on the
24th March 1878.
I, MARTIN TOBIN, of Leeds, in the County of York, Gentleman, do
hereby declare the nature of the said Invention for "AN IMPROVED
MEANS OR MODE OF VENTILATING ROOMS OR APARTMENTS AND IN THE APPARATUS
EMPLOYED THEREFOR," to be as follows:-
The object of my Invention is to arrange an apparatus in such a
manner and in such a position that a suitable quantity of atmospheric
air can be admitted into any apartment, and in such manner that as the
air passes into the room or apartment it is caused to take an upward
fountain-like direction and afterwards to become diffused therein without
any draft or inconvenience to the occupants.

I by preference perforate the lower bar of the upper sash of the
window or windows with any required number of holes or slots in a
vertical direction from inside through to the outside. Over these holes
or slots I provide a sliding cover or grate, which I make either to slide
laterally or longitudinally, by sliding which the holes or slots may be 5
covered to any required extent, and so admit into the room or apartment
any required amount of atmospheric air. I also arrange the slide to
connect the upper and lower sashes together so that the window when
closed cannot be opened from the outside. For this purpose I provide a
grooved plate on the opposite sash to the one on which the slide is 1
placed. Into this grooved plate when required the slide is pushed, con-
necting thereby the upper and lower sashes. I retain the slide in
position by a suitable catch or set screw.
Any convenient cover for the purpose of regulating the admission of
atmospheric air through the holes or slots may be employed. The top 1
rail of the lower sash may also be perforated in the same manner as the
bottom rail of the upper sash, and provided with a sliding or other
cover.
In some cases when the above described arrangement cannot be con-
veniently employed for admitting air I pass a tube or provide an opening 2
through into the apartment and form or turn the mouth or inlet so as to
give the air as it enters the apartment an upward or fountain-like
direction.
The amount of air admitted may be varied or regulated by adjustable
cap or slide.

SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Martin Tobin in the Great Seal Patent Office 30
on the 23rd September 1878.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of March, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Martin Tobin, Her special
licence that I, the said Martin Tobin, my executors, administrators,
and assigns, or such others as I, the said Martin Tobin, 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
MEANS OR MODE OF VENTILATING ROOMS OR APARTMENTS AND IN THE APPARATUS
EMPLOYED THEREFOR," upon the condition (amongst others) that I, the
said Martin Tobin, 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.
NOW KNOW YE, that I, the said Martin Tobin, do hereby 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, reference being had to the accompanying Drawings
and to the letters of reference marked thereon, that is to say :-
The object of my Invention is to arrange an apparatus in such a
manner and in such a position that a suitable quantity of atmospheric
air can be admitted into any apartment and in such manner that as the
air passes into the room or apartment it is caused to take a vertical
fountain-like direction and afterwards to become diffused therein without
any draught or inconvenience to the occupants.
In order that my Invention may be more completely understood
reference is given to the accompanying Sheet of Drawings, which shew
various modes of applying my Invention.
I perforate either the lower bar of the upper sash or the upper bar of
the lower sash of the window or windows with any required number of
holes or slots in a vertical direction from inside through to the outside.
Over these holes or slots I provide a sliding cover or grate, which I make

page_text: either to slide laterally or longitudinally, by sliding which the holes or
slots may be covered to any required extent, and so admit into the room
or apartment any required amount of atmospheric air.
In some cases when the above described arrangements cannot be con-
veniently employed for admitting air I pass a tube through into the
apartment and form or turn the mouth or outlet so as to give the air as
it enters the apartment a vertical fountain-like direction. These tubes
may be carried to any required position in the apartment.

page_text: required, as shewn, so that a sufficient amount of air may be admitted
into it to supply all the branches and smaller outlet tubes j. The
amount of air is varied or regulated by the stop valves k. These tubes
are by preference placed below the floor.
Those parts of the above described tubes which are in the room or
apartment may be so placed as to pass through statuettes or otherwise
concealed by some suitable ornamental work.
It will be readily understood by the herein described arrangements
that a continuous current of cold fresh air may be conveyed and intro-
duced into the room in a vertical direction, as shewn by arrows, to a
height varying in accordance with the strength of the current, and then
diffuses itself into the room or apartment without causing the slightest
draught or inconvenience to the occupants, producing a pleasant and
equable temperature, serving also to drive out the vitiated air, thus
answering all the requirements of ventilation.
Having now described the nature of my Invention, and the manner
in which the same may be performed, I would remark in conclusion that
I do not limit myself to the exact limits, details, and configuration of
parts I have explained and shewn, as the same may of course be varied
or modified without in any way departing from the nature of my
Invention, but what I do claim and desire to be secured to me by Letters
Patent are,-
Firstly. The arrangement and application of holes c or slots & with
regulating covers or gratings e, substantially as and for the purposes
herein set forth.
Secondly. The arrangement and application of tubes for carrying and
