PROVISIONAL SPECIFICATION.
Improvements in Draught and Dust Excluders and Water-bars for
all House and other Doors and Windows, Showcases and
Wardrobes, and the like.
I JOSEPH AMSON of 23 John Street Lozells Birmingham in the County of Warwick
Joiner do hereby declare the nature of this invention to be as follows:-
A simple arrangement of cams, levers, or their equivalent, attached to & worked by
a horizontal bar which is acted upon by the closing of the door or window or such
like in such a manner that it gives by compressing a spring a perpendicular move-
ment to a bar so arranged that when the door or window is closed, to fill or close
any aperture of a reasonable width or depth.
The spring is so arranged that in the event of any obstacle being placed in the
space purposely or accidentally it will not in any way damage the bar, spring, or
mechanical arrangement.
The whole of the mechanical appliances are enclosed in a case or shell of brass
copper, zinc, iron, or other suitable material which prevents any dust, or dirt from
detrimentally affecting the working parts.

COMPLETE SPECIFICATION.
Improvements in Draught and Dust Excluders and Water-bars for
all House and other Doors and Windows, Showcases and
Wardrobes, and the like.
I JOSEPH AMSON, late of 23 John Street Lozells Birmingham, in the County of
Warwick, now of 15, Trafalgar Road Handsworth in the County of Stafford, 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:-
DESCRIPTION OF DRAWINGS.
Figure (1) is an elevation shewing weather bar in position with door open.
Figure (2) is an elevation shewing weather bar in position with door shut.
Figure (3) is an end view shewing weather bar fixed to door when open.
Figure (4) is an end view shewing weather bar with strip down, door shut.
Figure (5) is a longitudinal section shewing position of mechanical arrangement
with door open and strip up.
Figure (6) is a longitudinal section shewing mechanical arrangement with door
shut and strip down.
Figure (7) is a plan of slide bar (D) and inner case (C).
Figure (8) is an end section door open and strip up.
Figure (9) is an end section door closed and strip down.
Figure (10) is an end section shewing weather bar inserted in edge of door
also shewing extension of inner case (C) for the purpose of securing the same.
In applying my improvements I use a case (A) of wood, metal, or other suitable
material, the inner side of which is formed to admit a strip (B) of wood or other suitable
material, and an inner case (C) Figures, 1, 2, and 7, of iron, brass, or other metal, which
contains a mechanical arrangement, consisting of a horizontal slide bar (D) and cams E. E.
and F. F. which operate on longitudinal spring (G) this spring is supported in the centre
by a fulcrum H and is secured at each end by screws to strip (B) the rod (I) is a
ונ..

page_text: continuation of slide bar (D) projecting beyond end of case (A) and consequently
coming in contact with door jamb when closing the door imparts a horizontal
movement to slide bar (D) and by forcing cams F. F. against cams E. E. thus depressing
spring (G) thereby giving a perpendicular motion to strip (B) the spring (G) extending
beyond points of cams E. E and F. F. leaves the strip (B) quite flexible allowing it
to suit itself to any incline of threshold and proof against damage by coming in
contact with any obstacle which may accidentally get underneath the door.
The
rod (I) is so arranged at connection with slide bar (D) as to form a regulator by
means of which the strip may be used as a weather bar, for excluding dust, draught,
& water, or by screwing end of rod (1) level with end plate (J) it may be utilised
as a ventilator. The cams F. F. work upon pivots secured in slide bar (D) which is
slotted to receive the same, the cams E. E. work upon hollow steel pivots K. K.
which are secured in inner case (C). (L) is a slotted plate which serves as guide
to strip (B).
When required, instead of using outer case (A) my improvement may be inserted
in the edge of doors, windows & the like.
Having now fully described and ascertained the nature of my improvements
and in what manner the same is to be performed, I declare that what I
claim is
(1) Inner case (0) which contains the mechanical arrangement thereby thoroughly
protecting the same.
(2) Longitudinal spring (G) and combination of cams E. E. and F. F. operating
on spring (G) and mode of operation which allows strips when depressed to be quite
flexible.
(3) Hollow steel pivots K. K. and H which allow screws to pass through for the
purpose of securing inner case () to outer case (A).
