Improvements in Dust, Draught, and Rain Excluders.
I, EDWIN POLLARD, of Keighley Road, Silsden, 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 :-
. This invention has for its object the construction of draught and dust excluders
such as are suitable for fixing to doors, windows and the like, and arranging them
in such a manner that, the spring for operating the movable portion of the excluder
is simplified in construction and application, effective in its action, less costly and
applied in such a way that, it does not come in contact with the door or the like,
and acts upon the movable portion of the excluder with less friction than is the
case with excluders having springs arranged in the manner as hitherto.
In explaining my invention in detail, reference is made to the accompanying
sheet of drawings in which
Fig. 1 represents an elevation showing the spring supports of a draught excluder
constructed according to my invention.
Fig. 2 is an enlarged cross sectional view through the excluder.
Fig. 3 is an elevation of a portion of the front view of an excluder.
Fig. 4 is an end view of the same, and
Fig. 5 a detail showing one of the brackets or spring supports.
The excluder is applicable to doors, windows and the like, and in carrying out
my invention, the lath A. may be secured to the door or the like in the ordinary
manner. To the lath A. is hinged in a novel manner the excluding lath B. the
bottom edge of which may be cut to the contour of the window sill or door
threshold.
The laths A. and B. are hinged together by a round bar C. which also forms
the spring and is inserted in the joint D. between the said laths, the bar C. passing
through the openings in the brackets or supports E. E' and F. F thereby com-
pleting the hinge, and is passed through in such a manner that, the said bar is
free in the brackets E. and F. but secured to the other brackets E and F by the
respective pins G. and G¹, the pins passing through the brackets and each pin
engaging with a notch or indentation cut in the bar C, so that the bar C. is
secured to the brackets or supports E¹ and Fi and cannot rotate or twist therein,
but the bar is free to twist in the other brackets or supports E. and F.
By securing the bar C. to the brackets or supports E and F and attaching one
bracket or support to the fixed lath A. and the other to the moveable lath B, on
moving the latter towards the door or the like; by the bar C. being held secure
in the brackets E' and F¹ the said bar will be twisted or torsion applied, so that,
as will be readily understood, on the liberation of the said lath, the twist or torsion
in the bar will react, causing the lath B. to return to its normal position.
It will be obvious that other means may be used for securing the bar C. to the
brackets or supports E' and F', such as forming the portion of the bar C. square
passing through the bracket E', also a portion of the said bar square for insertion
in the other bracket or support F, but this system involves a great expenditure of
labour, whereas by the application of a round bar C. and securing same to the
brackets or supports E and F in the manner described, considerably less labour
is involved.
The lath B. may be pressed to close the opening at the bottom of the window

page_text: or door by any convenient or well known appliance. In the drawings I have
shown a method which is capable of ready adjustment and consists of a spring
bar J. attached near to one end to the back portion of the lath B. and may be
inserted in a recess as shown, or level with the face of the lath. A screw K.
passes through the lath and engages with the said spring bar J. so that on
turning the said screw, the outer or protruding end of the spring bar J. is adjusted
to the required position, and when packed with a hard substance between the
spring bar and lath, it is there secured on tightening the screw K. so that on
closing the door or the like, the protruding end of spring bar J. comes in contact
with the door frame or the like, thereby operating the lath B. so that the bottom
edge of the same is held tight to the threshold.
The protruding end of the spring bar J. may be readily removed on with-
drawing the screw K, so that the lath B. is inoperative on opening or closing
the door or the like, thus allowing air to be admitted into the building under the
door, should it be desirable during the summer months, without having to remove
the excluder from the door.
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. The laths A. and B. combined with a bar C. mounted in brackets E. E' and
F. F¹, the bar C. being secured to brackets E' and F in a manner so as to prevent
rotation or twisting therein, all arranged substantially in the manner and for the
purpose as hereinbefore set forth.
2. The laths A. and B. having a spring hinge bar C. enclosed in the joint D.
combined with an adjustable spring bar J. arranged substantially in the manner
and for the purpose as hereinbefore set forth.
