Complete Specification Left, 28th June, 1892-Accepted, 30th July, 1892
PROVISIONAL SPECIFICATION.
Improvements in the Apparatus for Excluding Draught from
Railway Carriages.
I, JOSEPH TELLING of 40 Farnsby Street, Swindon in the County of Wilts,
Cabinet Maker do hereby declare the nature of this invention to be as follows:-
My invention relates to the arrangement, in a railway carriage door, of a hinged
flap lettered A. on the drawing herewith.
This flap A is hinged to the lower margin of the bottom rail B of the sliding
light frame.
At the back of the flap A. I arrange a spring C in such a manner that, when the
sliding light is raised, the flap A is thrown by it into the position shewn in Fig. 1
on drawing herewith.
In this position the flap A entirely closes the orifice of the "well" in the door,
represented by the space between the "garnish rail" D and the check plate E,
and so prevents the passage of any draught.
I arrange a plate F on the "garnish rail" as shewn on the drawing, in such a
position that the flap A rests upon it when the sliding sash is raised and closed.
Now by this means and the inclined position of the flap A I utilize the weight
of the sliding sash B to force the sash frame firmly against the outer margin of
the groove in the door pillar, represented by the line G, so preventing the passage
of draught between those surfaces into the railway carriage.
Fig. 2 represents the position assumed by the flap A. when the sliding sash is
being lowered.
It will now be seen that by the combination of the hinged flap A on the inside
of the sliding sash with the spring C and the plate F arranged as shewn by the
drawing herewith and acting in the manner described above, I obtain an apparatus
which serves the double purpose of automatically closing the orifice of the "well"
in the railway carriage door and of forcing the sash frame against the outer margin
of the sash groove in the door, so preventing the passage of draught into the
railway carriage.

Improvements in the Apparatus for Excluding Draught from
Railway Carriages.
1, JOSEPH TELLING of 40 Farnsby Street, Swindon, in the County of Wilts,
Cabinet Maker, 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 :-
My invention relates to the arrangement, in a railway carriage door, of a hinged
flap lettered A on the drawings left with my Provisional Specification.
This flap A is hinged to the lower margin of the bottom rail B of the sliding light
frame.
At the back of the flap A I arrange a spring C in such a manner that, when
the sliding light is raised, the flap A is thrown by it into the position shewn
in Fig. 1.
In this position the flap A entirely closes the orifice of the "well" in the door

page_text: represented by the space between the "garnish" rail D and the check plate E, and
so prevents the passage of any draught.
arrange a plate F on the "garnish" rail as shewn on drawings in such a
position that the flap A rests upon it when the sliding sash is raised and
closed.
Now by this means and the inclined position of the flap A I utilize the weight of
the sliding sash B to force the sash frame firmly against the outer margin of the
groove in the door pillar represented by the line G, so preventing the passage of
draught between those surfaces into the railway carriage.
Fig. 2 represents the position assumed by the flap A when the sliding sash ist
being lowered.
It will now be seen that by the combination of the hinged flap A on the inside of
the sliding sash with the spring C and the plate F arranged as shewn by the
drawings left with the Provisional Specification and acting in the manner described
above I obtain an apparatus which serves the double purpose of automatically
closing the orifice of the "well" in the railway carriage door and of forcing the
sash frame against the outer margin of the sash groove in the door; so preventing
the passage of draught into the railway carriage.
Having now particularly ascertained and described the nature of my said
invention, I declare that what I claim is,-
1. The combination in a railway carriage door of a flap A on the inside of the
sliding sash with the spring C and the plate F arranged as shewn on the drawings
and acting in the manner described above.
2. The combination, on the inside of a sliding sash, of the flap A, with the
spring C and plate F to automatically close the orifice of the door "well" and
force the sash against the outside margin of its groove.
Dated this 25th day of June 1892.
