PROVISIONAL SPECIFICATION.
An Improved Weather-bar and Draught-excluder.
THOMAS WOODWARD Bentley Doncaster Yorkshire Carpenter and Joiner do hereby
declare the nature of this invention to be as follows';―
An improved weather bar which may be fixed in a longitudinal groove cut in the
bottom of a door, or in a rebate, so as to be invisible, or fixed in a rebate at the back
of a piece of moulded wood, screwed on the face of a door. It may be also fixed at
the top or sides of doors or casements.
The invention consists principally in the simplified action or mechanical contrivance
by which the bar opens and closes, whenever the door is opened and closed. By my
new arrangement of the working parts of the bar all springs, cranks and adjustable
screws are superseded and rendered unnecessary.
The door or casement opens and the weather bar is raised instantly; the door is
closed, and the bar falls and closes the space through which rain, draughts, or dust
could come.
This motion is brought about by two arms or levers which are weighted with
lead or otherwise, and are pivoted on pins just above the bar in this manner.-One
end of each arm or lever is connected with the bar by two pivoted swinging arms,
one for each end, and the other ends, which are weighted are held together in a slot
hinge in the centre and just above the bar. When the two levers are down by their
own weight, they are in a straight line, and parallel with the bar which is then held
up. When the arms or levers are raised in the centre they form a wide angle, and at
the same time the ends which are not weighted force down the bar below the level of
the door bottom, and it thus closes up the space and prevents draught. A pro-
jecting pin or plate is fixed on one or both ends of the lever arms, and on the
door being closed this projection comes in contact with a plate, somewhat oval in
shape, which is fixed on the door frame and the pin on the lever ends is forced down;
the weighted ends of the levers are raised, forming an angle; and the bar is forced
downwards.

The position of the plate on the Coor frame will regulate

COMPLETE SPECIFICATION.
An Improved Weather-bar and Draught-excluder.
THOMAS WOODWARD Bentley Doncaster Yorkshire Carpenter & 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 the construction of a weather bar having a simplified
and more certain actuating mechanism than those hitherto known. It can be fixed
in the same position as other weather bars are fixed; either in a longitudinal groove
cut in the bottom of a door, or in a rebate, so as to be invisible, or fixed on a rebate
at the back of a piece of moulded wood, screwed on the face of a door. It may also

bo fixed at the top or sides of doors or casements, but its principal application will be
at the bottom of doors.
By my arrangement of the working parts of the bar, all springs, cranks, and
adjustable screws are superseded and rendered unnecessary. When the door is closed,
the bar falls, and closes up the space through which rain, draughts or dust could
come. When the door is opened the bar is instantly lifted, and kept raised until the
door is again closed.
This falling and lifting of the bar applies to all weather bars of a like description,
and my invention only consists in the new and simplified action or mechanical con-
trivance which enables the bar to rise and fall.
By reference to the accompanying sheet of drawing, the invention will be best
described and understood.
Fig. 1 shows the bar raised when the door opens.
Fig. 2 is a transverse section of the same.
Fig. 3 shows the bar down, when the door closes.
Fig. 4 is a transverse section of the same.
Figs. 5-7 are full sized parts, hereinafter referred to.
Fig. 6 shows the position of har and other parts fixed on a door.
Referring to Figs. 1-2. E is a piece of wood moulded, a section of which is shown
in Fig. 2. E, and it is screwed on the face of a door. It is rebated so as to contain
the bar and its working parts, A. F. Fig. 2. It is in fact only a cover for them. This
rebate may be also fixed in a groove in the door itself.
Referring now to Fig. 1. A. A are two arms or levers which are weighted with
lead or otherwise Fig. 1. B. B. and are pivoted on pins N. N, which pins are held in
a clip, the tang of the clip G being morticed through the bridge R. R. One end of
each arm or lever is connected with the bar by a pivoted swinging arm or link, D. D.
and the other ends which are weighted are held together in a slotted hinge K, in the
centre and just above the bar F F.
When the two levers are down by their own weight, they are in a straight line, and
parallel with the bar, which is then held up as shown in Fig. 1.
When the arm or
levers are raised in the centre, they will form an angle, and at the same time the ends,
which are not weighted, force down the bar below the level of the door bottom
as shown in Figs. 3-4, and it thus closes up the space or opening and prevents a
draught.
A projecting pin or plate is fixed on one or both ends of the lever arms, that is to
say, one on each lever, or one only, as shown in Fig. 6. On the door being closed,
this projection Fig. 7. comes into contact with a striking plate, somewhat oval in
shape, Fig. 5, and this plate is fixed and sunk into the door frame Fig. 6. M. if the
bar is in a groove in the door itself; but if the bar is in a rebate on the face of the
door, the plate is fixed outside the door frame accordingly.
The position of this plate on the door frame will regulate the adjustment of the bar,
it is held in any position by the screw B. Fig. 5.
As soon as the projecting pin or plate comes into contact with the striking plate,
the lever ends are forced downwards, and their weighted ends are then raised forming
an angle, and the bar is forced down.
As soon as the pin is released from the pressure of the plate, when the door is
opened, the 2 levers drop, the bar is then lifted and kept up, until the door is again
closed.
Fig. 5 shows the direction taken by the pin C. when brought into contact with the
plate P.
Fig. 7 shows the pin C, and how it can be fixed on the bar F.
I do not limit myself to the exact details herein before described, as they may be
varied without departing from the nature of my invention. I do not claim any of
the parts separately which are well known, and 1 do not limit myself to the use of any
of the materials which are named, such as lead for weighting the lever ends..
The bar may be simply wood, or wood that is covered with some soft material, so
as to make a perfect joint. It can, be shaped also to suit a worn away floor or step.

page_text: 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 1
claim is―
1. The new and simplified arrangement of the actuating mechanism which raises
and lowers the weather bar, and in particular the use of weighted arms or levers
which are fixed and worked substantially as herein described and illustrated by the
annexed sheet of drawings.
2. The striking plate, attached to the door frame by a central screw, which enables
a perfect adjustment of its position to be made in relation to the pin or plate which
comes into contact with it when the door is closed, substantially as herein described.
Dated this 12th day of December 1890.
