PROVISIONAL SPECIFICATION.
Draught, Rain, and Dust Excluder for the Bottom of Doors.
WILLIAM HENRY BARWELL of Radcliffe-on-Trent in the County of Nottingham
do hereby declare the nature of this invention to be as follows:-
:-
It is formed of wood of which there is two peiceses of equal length one about 1 inch
by 3 inches and the other about inch by 2 inches the former I shall term the fixed
part which is secured to door and the latter I shall term the free part which is made
to rise and fall by the opening and closing of the door the fixed part is rabbeted on
the side towards the door and on the bottom edge about 2 inches by inch thus
leaving a space between the face of door and the fixed part for the free part to move
freely up and down.
The necessary up and down movement of the free part is preformed in the following
manner, on the side towards the door of fixed part is secured two iron plates which
extend downwards the lower ends of these plates have slots in them through each a
screw is passed and screwed into free part thus forming a guide for the up and down
movement of free part, on cach of mentioned plates and on the side of them from the
door is a small stud on each of which works a crank lever to which is connected a
flat bar of iron which traverses the top part of rabbet of fixed part and extends to
either ends which may be desired at the end of this bar of iron is a set screw which is
to regulate the action of bar and crank levers.
When the Draught Excluder is fixed on door and the door is open the set screw in
the end of bar projects a little past the end on the hanging side of door and the free
part is raised by a wire spring which is secured to fixed part in the centre and the
ends are connected to free part by small eyes through which it moves freely.
When the door is closed the head of screw in the end of bar comes in contact with
a small metal plate let into door frame on the side to which the door is hung which
forces the bar forward and it being connected to the upper end of crank levers causes
the lower end of crank levers to press upon the top edge of free part thereby forcing
down firmly on to door sill making a perfect joint.

Draught, Rain, and Dust Excluder for the Bottom of Doors.
1 WILLIAM HENRY BARWELL Radcliffe-on-Trent in the County of Nottingham
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 THE DRAWINGS.
Figure 1 shows a side view of the bottom of a door provided with a drought, rain
and dust excluder, in the position it occupies when the door is open.
Figure 2 shows a side view of the excluder in the position it occupies when the
door is closed. In both Figures the lower part of the door is broken away to show
the whole of the moulding carrying the excluder.
Figures 3 and 4 are end views of Figures 1 and 2.
Each draught, rain and dust excluder consists of two pieces of wood of equal
length, the first piece A forms a moulding of any required shape secured to one side
of the bottom of the door B, the side of the moulded piece next the door is rabbited
from the bottom for about two-thirds of its depth to allow of a second piece C to slide
freely between it and one side of the bottom of the door.

page_text: The piece C is raised into the position shown at Figures 1 and 3, when the door
is open, and lowered to exclude draught rain and dust into the position shown at
Figures 2, and 4, when the door is closed by the following means.
To the side of the piece A next the door two vertically slotted metal plates Care
secured, in each slot a stud C2 projecting from the piece A slides, each plate is
provided with an axle pin on one side, on which a two slotted double ended crank
lever Crocks in the corresponding slot of each lever a stud D, projecting from a Hat
bar D' engages, the bar is slotted near one end and slides upon a stud D³ secured in
the piece A, the outer end of the bar is provided with a set screw and lock nut D' by
which the lateral traverse of the bar may be regulated.
When the door to which the excluder is fixed is open the set screw projects a little
past the end of the piece A on the hanging side of the door as shown at Figure 1,
but when the door is closed the set screw pressing upon the door frame, or upon a
small metal plate let into the door frame, will force the bar D' into the position shown
at Figure 2 the studs D, rocking the levers C³ and forcing the sliding excluding
piece C down firmly on to the door cill. The two slots in the crank levers C³ provide
means for reversing the bar D' so that the set screw will project from the right end
of the piece A when applied to a door opening the opposite way.
As the door is opened the piece C is raised into the position shown at Figures 1,
and 3, by a steel wire spring E, which is secured at the centre of its length to the
piece A, the ends of the spring sliding in metal eyes E' secured to the top of
the piece C, lifts it and holds it up until it is again lowered by the closing of 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 :-
The construction and employment of a draught rain and dust excluder substantially
as described and illustrated in the Drawings annexed.
