PROVISIONAL SPECIFICATION.
An Improved Appliance for Excluding Dust, Draughts and Rain.
I, EDWIN POLLARD, of Firth Street, Thornton, near Bradford, in the County
of York, Joiner, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct an appliance for doors and windows
for excluding dust, draughts and rain from the interior of rooms of houses and other
places in an automatic and efficient manner.
I accomplish my object in the following manner-I secure to either or both
sides of the door or window, a strip of wood or other suitable material, to
which is hinged a bar extending the width of the door or window opening; the
bottom edge of the hinged bar is cut to the surface of the door threshold or
window sill, and is covered with india rubber or other flexible material for more
effectually closing the space.
One or more springs are attached to the door or other convenient support in
such manner as to act on the hinged bar, so that the same is pressed outwards
from the door or window clear of the threshold or window sill, on the door or
window being opened.
An arm is attached to one end of the hinged bar in such position that, on
closing the door or window, the arm comes in contact with some fixed point,
thereby forcing the hinged bar downwards, with its lower edge pressed tight on
the floor or sill, the flexible material adapting itself to any irregularities in the
threshold or sill, thus effectually closing any space under the bottom of the door
or window, thereby excluding any wind, dust or rain.

COMPLETE SPECIFICATION.
An Improved Appliance for Excluding Dust, Draughts, and Rain.
I, EDWIN POLLARD, of Firth Street, Thornton, near Bradford, in the County
of York, Joiner, 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:-
The object of this invention is to construct an appliance for doors and windows
for excluding dust, draughts and rain from the interior of rooms of houses and
other places in an automatic and efficient manner.
In describing my invention in detail reference is made to the accompanying
drawings, in which
Fig. 1 represents a portion of my improved apparatus applied to the outside of a
door.
Fig. 2 a similar view showing the apparatus fixed to the inside.
Fig. 3 an elevation of the bottom portion of a door when closed, showing the
draught excluding bars in contact with the door threshold.
Fig. 4 an elevation of the bottom portion of the door when open, showing the
draught excluding bars elevated, and
Fig. 5 an enlarged detail view of the back part of a portion of a draught
excluder.
Similar letters indicate like parts where they appear.

page_text: I secure to one or both sides of a window or door A. a lath of wood or other
material B. to which is hinged an excluding bar C. extending the width of the
window or door opening, the bottom edge of the said bar being cut to corre-
spond with the surface line D. of the window sill or door threshold, and in
order to more effectually close the opening between the hinged bar C. and
window sill or door threshold line D. the bottom edge of the said bar may be
covered with a strip of india rubber C¹ or other Hexible material which on
pressure will yield to the irregularities of the surface.
To the strip B. is secured a metal plate E. upon which the end of flat
spring F. rests, the said spring being bent and secured to the hinged bar C. in
such a manner that, on opening the window or door the hinged bar C. is forced
outwards.
The hinged bar C. fitted to the outside of the window or door is provided
with a plate G. secured near to one end of the same, which, on closing the
window or door, comes in contact with a projection H. secured to the stile or
other fixture, thereby causing the bar C. to move on its hinges and compress
the springs F. at the same time closing the aperture between the bottom edge
of bar C. and threshold.
To one end of the hinged bar C. secured on the inside of the window or door
is attached an arm J. which on closing the window or door, the upper end of
said arm comes in contact with the fixed casement or stile, thereby operating
the arm J. and hinged bar attached thereto, forcing the latter downwards with
its lower edge against the sill or threshold line D. the flexible material adapting
itself to any irregularities in the surface of the stile or threshold, thus effectually
closing the space under the bottom of the window or door, thereby excluding
any wind, dust or rain.
:
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
-
1. The combination of the metal plate E. secured to lath B. with the spring F.
secured to bar C. for the purpose hereinbefore set forth.
2. The combination of the parts forming the complete apparatus arranged
substantially as and for the purpose set forth and illustrated by the accom-
panying drawings.
