We, JOHN CHARLES TAITE, and THOMAS WILLIAM CARLTON, both of 63 Queen
Victoria Street, in the City of London, Engineers, and THOMAS WILLIAM WORSDELL,
of Hermon Hill, Wanstead, in the County of Essex, Engineer, do hereby declare the
nature of said invention for "DRAUGHT AND DUST EXCLUDERS OR APPARATUS TO
BE USED IN CONJUNCTION WITH RAILWAY CARRIAGE AND OTHER WINDOWS OR THE
LIKE ARRANGED TO SLIDE OR BE LOWERED INTO DOORS CHAMBERS OR CASINGS TO
PREVENT DRAUGHT AND DUST ENTERING COMPARTMENTS OR ROOMS WHEN SUCH
WINDOWS OR THE LIKE ARE CLOSED," to be as follows:-
This invention relates to draught and dust excluders or apparatus to be used in
conjunction with windows or the like arranged to slide or be lowered into doors
boxes chambers or casings to prevent draught and dust entering compartments or
rooms when such windows or the like are closed.
As is well known where windows or shutters are arranged to be lowered into
boxes or chambers such as those formed in the bodies of railway and other carriage
doors and in houses between the outer walls and panellings skirtings or linings,
when the windows or shutters are raised up into their closed positions, draught and
dust are liable to enter the carriage or room through the box or chamber that
serves to receive the window or shutter when lowered.
Now this invention is designed to obviate these evils-For this purpose the
chamber intended to receive the window or shutter when lowered is furnished
according to this invention with a flap or plate able to turn on a hinge or hinges so
as to allow of the window or shutter being lowered, and in connexion with such
flap or plate is or are provided a spring or springs, the arrangement being such
that when the window or door is raised into the closed position the flap or plate
will be caused by the action of the spring or springs to assume a position in which
the upper opening or mouth of the box or chamber out of which the window or
hutter has been raised will be closed so as to prevent entrance thereby of air or
lust into the carriage or room as the case may be.

page_text: To enable the nature of the invention to be clearly understood the following
description of its application to a carriage door is given by way of example.
The flap or plate is fixed to the garnish rail of the door by hinges, the garnish
rail being recessed to admit of the flap when down and not in use it being then
flush with the inside of the rail.
A spring also fixed to the garnish rail is so arranged that
presses upon the
inner side of the flap. When the sash is down the flap is pressed home by means
of the sash against lugs fixed at each end of the flap which lugs may be made of
either metal or hard wood or in the form of rollers.
Immediately the sash is raised into its closed position the flap is released from
pressure, and the spring forces it into a horizontal position completely filling up the
space between the garnish rail and light rail. The same arrangement is intended to
apply to any windows or shutters that are operated in a like manner to those in
carriage doors.

We, JOHN CHARLES TAITE and THOMAS WILLIAM CARLTON, both of 63 Queen
Victoria Street, in the City of London, Engineers, and THOMAS WILLIAM WORSDELL,
of Hermon Hill, Wanstead, in the County of Essex, Engineer, do hereby declare the
nature of said invention for "DRAUGHT AND DUST EXCLUDERS OR APPARATUS TO
BE USED IN CONJUNCTION WITH RAILWAY CARRIAGE AND OTHER WINDOWS OR THE
LIKE ARRANGED TO SLIDE OR BE LOWERED INTO DOORS CHAMBERS OR CASINGS TO
PREVENT DRAUGHT AND DUST ENTERING COMPARTMENTS OR ROOMS WHEN SUCH
WINDOWS OR THE LIKE ARE CLOSED," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to draught and dust excluders or apparatus to be used in
conjunction with railway carriage and other windows or the like arranged to slide
or be lowered into doors boxes chambers or casings to prevent draught and dust
entering compartments or rooms when such windows or the like are closed.
As is well known where windows or shutters are arranged to be lowered into
boxes or chambers such as those formed in the bodies of railway and other carriage
doors and in houses between the outer walls and panellings skirtings or linings,
when the windows or shutters are raised up into their closed positions, draught and
dust are liable to enter the carriage or room through the box or chamber that
serves to receive the window or shutter when lowered.
Now this invention is designed to obviate these evils. For this purpose the
chamber intended to receive the window or shutter when lowered is furnished
according to this invention with a flap or plate able to turn on a hinge or hinges so
as to allow of the window or shutter being lowered, and in connexion with such
flap or plate is or are provided a spring or springs, the arrangement being such
that when the window or shutter is raised into the closed position the flap or plate
will be caused by the action of the spring or springs to assume a position in which
the upper opening or mouth of the box or chamber.out of which the window or
shutter has been raised will be closed so as to prevent entrance thereby of air or
dust into the carriage or room as the case may be.
Referring to the accompanying sheet of drawings Fig 1 is a vertical section of a
railway carriage door having apparatus according to this invention applied thereto
and Fig 2 is an elevation of the door with portions of the outer panel and frame-
work removed. Figs 3 and 4 are detail views drawn to an enlarged scale.
A is a flap or plate secured to the garnish rail A' by hinges A². As is a recess to
receive the flap when down out of use. B. B. are springs fixed to the garnish rail

page_text: and arranged to press upon the under side of the flap A and C. C are lugs or
projections (they may be in the form of rollers) against which the sash presses so
as to force the flap against the garnish rail when the sash is lowered..
It will be seen that when the sash is raised into its closed position (shown in
Figs 1 and 3), the flap being relieved of pressure from the sash is forced by the
springs B into a position beneath the sash completely closing the space between the
garnish rail and light rail and excluding draught and dust from the carriage.
The same arrangement is intended to apply to any windows or shutters that are
operated in a like manner to those in carriage doors.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is
1. The application and use in connection with a window or shutter and a box or
chamber into which the same can be lowered of a flap or plate for excluding
draught and dust so arranged that when the window or shutter is raised into its
closed position the flap or plate will be automatically closed and that as the window
or shutter is lowered it will cause the flap or plate to move downward so as to allow
the window or shutter to descend into its box or chamber in the manner herein-
above described with reference to and illustrated in the drawings annexed.
2. The apparatus constructed arranged and operating as hereinbefore described
with reference to and shewn in the drawings for the purposes specified.
