Improvements in Draught Excluders for Doors.
I, THOMAS WALTER TUCKER of 39, Blenheim Road, Lower Barton Street,
Gloucester, Carriage Builder, 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:-
This invention relates to an improved draught excluder for doors and is especially
intended for use in railway and other carriage doors, and has for its object to
provide a simple and inexpensive means which will effectually prevent the passage
of draught, and will also act as a buffer preventing the noise commonly made in
closing railway carriage doors.
At the hinged side of the door I propose to place a strip of rubber of about half
an inch square in cross section, fixed by means of screws. This is fitted to the
door post in the rebate so that when the door is closed, the edge will bear on the
outer surface of the rubber strip, which is preferably rounded.
At the other side
a similar strip is fixed, and when the door is closed the check of the door will
press against the flat face of the rubber. Thus on closing the door the rubber
will lessen the noise commonly made, and at the same time completely fill up the
crack.
As applied to the bottoms of doors, the rubber is fixed in the bottom rail, a
groove being formed to receive it, and this bottom rail is preferably rebated.
This arrangement is especially useful for railway carriages, and the floor of the
carriage is also rebated, so that as the door closes the rubber strip will bear against
the edge of the floor. The arrangement for the top of the door is similar to that
described for the side.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which
Fig. 1 is a cross section of one side of the door,
Fig. 2 is a cross section of the opposite side, and
Fig. 3 is a longitudinal section of the lower part of a railway carriage door,
showing a portion of the door in section.
A is the door post rebated at a. In this rebate the rubber strip B is fixed by
means of the screws b, the outer face or edge of the strip being rounded as above
mentioned. The side rail C of the door, rebated at c at the hinged side, abuts
against the rounded edge of the strip, as shown in Fig. 1, the strip lying between
the rebates a and c. The rail C shown in Fig. 2 also rebated, bears when closed
against the front face of the strip, the face of the rebate abutting against the
said strip.
The arrangement shown in Fig. 3 for the bottom of the door consists in fixing
the strip B in the groove c¹ in the bottom bar C' of the door. The floor D is also
rebated at d, so that the strip bears against the face of the rebate. The protecting
plates d' are fixed on the edge of the floor to prevent the floor being worn.
As applied to ordinary doors, this arrangement for the bottom part is not
required.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) An improved draught excluder for railway and other carriage doors, con-
sisting of a rubber strin fixed in the rebate of the door post. against which the side

page_text: bars of the door bear, substantially as described and shown in Figs. 1 and 2 of the
annexed drawings and for the purposes specified.
(2.) An improved draught excluder to be applied to the bottoms of railway and
other carriage doors, consisting of a rubber strip fixed in a groove in the bottom
rail, the said bottom rail being rebated, and the edge of the carriage floor being
also rebated to correspond, substantially as described and shown in Fig. 3 of the
drawings, and for the purposes specified.
Dated this 9th day of April 1895.
