13 Princes Street, Tin Plate Worker, and HENRY ATKINSON LUND, 37 Oakworth
Road, Tin Plate Worker, all of Keighley, Yorkshire, do hereby declare the nature
of our invention for IMPROVEMENTS IN WEATHER BARS FOR THE DOORS
DWELLINGS AND OTHER BUILDINGS, to be as follows:-
OF
Our invention has reference to those weather bars, of the doors of dwellings and
other buildings, which are moveable, or in other words which are automatically
pressed or pushed down to cover the openings at the bottoms of doors (the said
openings being caused by the wearing away of the flags, or other materials
covering the ground, or the doors or both) when the said doors are closed and
raised or lifted, to clear the uneven ground, by the motions of the doors when
opening; and is applied as follows:
8
To the inner surface of that door post to which the door is hinged is also
hinged, in an appropriate position and bearings, a bar or connecting rod having
hinge joint near to that end which is binged to the door post, so that in working,
as will be hereafter described it will move parallel with the door's inner surface;
it is also made adjustable to facilitate its fixing. This bar or connecting rod
extends horizontally along the inner surface of the door at its bottom part coming
in contact with, and laying hold of, the end or ends of the upper arm or arms of
one, two or more levers as the case may be the number varying according to the
width of the door and consequently the work to be done. These levers are
fulcrumed on stands fixed to the door's inner surface, the said stands being formed
to overhang the weather bar and so form stays and guide pieces for it.
The lower arms of the aforesaid levers extend downward over the weather bar
for a suitable distance and at the outer ends of each of these levers is formed
an inclined slot which runs at an appropriate angle to the said lever arm until it
finally ends in a segment, the centre of which is the centre of each lever respectively.
Through each of these inclined slots at their lowest point where the most motion
of the lever is obtained from the motion of the door and through upright slots
formed in the beforementioned stays or guide pieces is inserted a small projecting
pin such as a common nail or preferably a screw which is fixed into the weather
bar. The weather bar is a thin piece of wood, or other appropriate material, of

page_text: suitable width and sufficiently long to cover all the opening at the bottom of the
door to which it is applied, when the said door is closed; the bottom edge of the
said weather bar is cut to fit closely the hollow or uneven ground.
From the foregoing, by noticing the difference in the relative positions of the
centres of motion of the door and the connecting rod, it will be seen that as the
door is being opened the rod is moved towards its (the door's) outer edge; thus
imparting a movement to the inclined slotted arms of the levers before mentioned
which presses the projecting pins or screws up the upright slots in the guide
pieces, bringing with them the weather bar to which they are attached, the
required distance; but instead of the lever continuing to lift the said weather bar,
after the required distance has been reached as the door opens further back the
segment or curved portion of the slotted arm allows the projecting pin or screw to
pass along it, which it (the lever arm) holds or locks up without further lifting the
weather bar. As the door is closing the reverse motion is imparted to the weather
bar until it is finally pressed down when the door is shut.
Several arrangements of parts may be employed to impart an upward and down-
.ward movement to the weather bar from the motion of the door by the difference
in the relative positions of the centres of motion of the door and the connecting
rod, such as joining the connecting rod direct with the weather bar and forming
inclined slots in the said weather bar instead of in the lever arm as before
mentioned through which projecting pins are inserted into the door, so that when
the door opens the connecting rod will press the weather bar outwards (that is
towards the outer edge of the door) and by the inclined slots lift it the required
distance, but in this case the end of the weather bar would project beyond the
outer edge of the door when it was open and so be very unsightly. Or again a
very similar result to this last mentioned may be obtained by hanging the weather
bar in pieces attached loosely to it and the door instead of using the inclined slots;
but preferably for neatness and to avoid backlash (which latter is of great
importance) we make use of the parts as set forth in the former part of our
description.

page_text: We, WILLIAM GREENWOOD, 95 Leeds Street, Mechanic, CHARLES MITCHELL,
13 Princes Street and HENRY ATKINSON LUND, 37 Oakworth Road, Tin Plate
Workers all of Keighley Yorkshire, do hereby declare the nature of our
invention for IMPROVEMENTS IN WEATHER BARS FOR THE DOORS OF DWELLINGS
AND OTHER BUILDINGS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
Our invention has reference to those weather bars, of the doors of dwellings and
other buildings, which are moveable or in other words which are automatically
pressed or pushed down to cover the openings at the bottoms of doors (the said
openings being caused by the wearing away of the flags or other materials or
the doors or both) when the said doors are closed and raised or lifted, to clear the
uneven ground by the motions of the doors when opening; and in order that our
said invention may be more easily understood we have hereunto appended a sheet
of drawings in which Fig. 1 is a back or inner elevation and Fig. 2 plan of a
common dwelling's door when closed, with a sufficient portion of its surroundings
to illustrate our invention. Fig. 3 is another elevation of same, when open.
To the inner surface of that door post 1 to which the door 2 is hinged, is also
hinged in an appropriate position and bearing 3, a bar or connecting-rod 4 having
a hinge joint a near to that end which is hinged to the door post 1, so that in
working as will hereafter be described it will move parallel with the door's
inner surface; it is also made adjustable at b to facilitate its fixing. This bar or
connecting-rod 4 extends horizontally along the inner surface of the door 2 at its
bottom part coming in contact with, and laying hold of, the end or ends of the
upper arm or arms of one, two or more levers 5 as the case may be, the number
varying according to the width of the door 2 and consequently the work to be
done. These levers 5 are fulcrumed on stands 6 fixed to the door's inner surface,
the said stands 6 being formed to overhang the weather bar 7 and so form stays
and guide pieces for it.
The lower arms of the levers 5 extend downward over the weather bar 7 for a
suitable distance and at the outer ends of each of the levers 5 is formed an inclined
slot which runs at an appropriate angle to the said lever arm until it finally ends
in a segment, the centre of which is the centre of each lever 5 respectively.
Through each of these inclined slots at the lowest point where the most motion of
the lever 5 is obtained from the motion of the door and through upright slots
formed in the beforementioned stays or guide pieces 6 is inserted a small projecting
pin 8 such as a common nail or preferably a screw which is fixed into the weather
bar 7. The weather bar 7 is a thin piece of wood or other appropriate material of
suitable width and sufficiently long to cover all the opening 9 (Fig. 3) at the
bottom of the door 2, when the said door is closed, the bottom edge of the
said weather bar 7 is shaped to fit closely the hollow or uneven ground 10.
From the foregoing, by noticing the difference in the relative positions of the
centres of motion of the door 2 and the connecting rod 4, it will be seen that as
the door 2 is being opened the rod 4 is moved towards its (the door's) outer edge;
thus imparting a movement in the direction of the arrow 11 to the inclined slotted
arms of the levers 5 and so presses the projecting pins 8 up the upright slots in the
guide pieces 6, bringing with them the weather bar 7 to which they are attached,
the required distance; but instead of the lever 5 continuing to lift the said weather
bar 7, after the required distance has been reached as the door
opens further
back the segment or curved portion of the slotted arm 5 allows the projecting pin 8

page_text: to pass along it, which it (the lever arm 5) holds or locks up without further lifting
the weather bar 7. As the door is closing the reverse motion is imparted to the
weather bar 7 until it is finally pressed down when the door is shut.
Several arrangements of parts may be employed to impart an upward and
downward movement to the weather bar from the motion of the door by the
difference in the relative positions of the centres of motion of the door and con-
necting rod, such as joining the connecting rod 12 direct with the weather bar 7
as shewn in Figs. 4 and 5 which are back elevations shewing the door 2 closed and
open respectively, and forming inclined slots 13 in the said weather bar so that
when the door opens the connecting rod 12 will press the weather bar 7 outwards
(that is towards the outer edge of the door) and by the inclined slots 13 lift it the
required distance, but in this case the end of the weather bar 7 would project
beyond the outer edge of the door when it was open (see Fig. 5) and so be very
unsightly. Or again a very similar result to this last mentioned may be obtained
by hanging the weather bar 7 in pieces 14 (Figs. 6 and 7, which are similar views
to 4 and 5 respectively) the said pieces 14 being attached loosely to the weather
bar 7 and the door 2 instead of using the inclined slots 13, but preferably for
neatness and to avoid backlash (which latter is of great importance) we make use
of the parts as set forth in the former part of our description.
1 Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The use and employment of the bearing 3, connecting rod 4, lever 5 and guide
piece 6 both separately and combined in the manner and for the purpose as herein
described.
2. The inclined slots 13 used substantially for the purpose as herein shewn.
3. The working of moveable weather bars by hinged connecting rods deriving
their motion in the manner as fully described and illustrated in the accompanying
drawings,
4. The adaptation of the pieces 14 for the purposes herein fully described and
set forth.
