PROVISIONAL SPECIFICATION.
Improvements in Weather-bars or Draught-excluders for Doors and
Hinged Windows.
I, JAMES WATERHOUSE MIDGLEY of Park Laue Works, Keighley in the
County of York, Machine Maker, do hereby declare the nature of this invention
to be as follows, that is to say :-
It has for its object the production of means for operating the apparatus known
as weather-bars or draught-excluders for doors and hinged windows or the like, that
shall perform such functions efficiently without causing any breakages or damages to
any of the parts when any obstructions are encountered by the weather-bar during
the performance of said functions.,
To attain this object I make use of the well-known kind of weather-bar and its
cover and bearings, however I couple the lever mechanism thereto by flexible joints
as by cord, chains or the like so that when these are forcibly moved, as on the
closing of the door to which they are attached should any article lie in the path of
motion of the weather-bar preventing its descent no hindrance is presented to the
free movements of these operating parts..
A spring arrangement is employed for retracting the parts brought into contact
with the door post or other stationary parts and such retraction of the spring
operates the bar as desired through the suitable lever connections and their flexible
joints.
Instead of lever mechanism being employed grooved pulleys or bowls may be
made use of together with cord, chain or other flexible coupling means.

Improvements in Weather-bars or Draught-excluders for Doors and
Hinged Windows.
1, JAMES WATERHOUSE MIDGLEY of Park Lane Works, Keighley in the
County of York, Machine Maker, 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, that is to say :—
It has for its object the production of means for operating the apparatus known
as weather-bars or draught-excluders for doors and hinged windows or the like, that
shall perform such functions efficiently without causing any breakages or damage to
any of the parts when any obstructions are encountered by the weather-bar during
the performance of said functions.
In the accompanying sheets of drawings ;-
Figs. 1 and 2 are elevation and end views respectively of a weather-bar made in
accordance with my invention, and in both the views the moveable strip is shown as
in its raised or elevated position.
> 11.

page_text: Fig. 3 is a similar view to Fig. 1. but shows the moveable strip in its depressed
position.
Figs. 4, 5, 6, 8 and 10 are similar views to Fig. 1 but are illustrative of
modifications hereinafter explained.
Figs. 7 and 9 are end views, drawn to an enlarged scale of the weather-bars
illustrated by Figs. 6 and 8 respectively.
The method of fixing the weather-bars to the doors or hinged-windows in
connection with which they have to be used being well known it is not herein
illustrated, while the several elevations shown by Fig. 1, 3, 4, 5, 6, 8
and 10 are illustrative of that side of the weather-bar which fits against
the door.
To attain the object of my invention I make use of the usual and well known
kind of moveable strip a and its cover b which also forms its bearings as is well
understood.
This strip a I couple to its operating mechanism by flexible connections which
connection in the case of the arrangement shown by Figs. 1 and 3 consists of the
chain c which couples the bar d to the lever e this latter being coupled by the rod f
to the lever el while both of these levers are pivotally attached to the strip a. The
bard is operated by being pressed against the jamb of the door on which it is
mounted, as said door is being closed, it being, by these actions pressed into the
position shown by Fig. 3 at which time the retracting spring g is compressed while
the strip a is allowed to fall by gravity. However should anything interfere with
the descent of said strip a then the chain c permits the movement of the bar d
although the strip a is not affected by such movement.
Instead of the levers e e¹ and rod f being employed the grooved pulleys h h¹ and
lever are made use of, as shown by Fig. 4, in which case the chain m forms the
flexible coupling. Or again, in place of the bar d, spring g and lever k being used
as shown by said Fig. 4 the simple flat spring n with its chain connections m¹ and
pulleys h h as shown by Fig. 5 might be employed.
The weather bars illustrated by the Figs. 1 to 5 and as hereinbefore described
are for operation by end pressure on the rod d and are so prepared for being mounted
on the outside of a door or the like, but my invention is equally applicable for use
in connection with those weather bars that are required to be mounted on the inside
as is the one shown by Fig. 6 in which case the strip a is coupled by the flexible
coupling chains o o¹ to the levers eel these latter being held or sustained in their
raised positions shown in the drawings, by the flat spring p while they are forced
down against the pressure of this spring p by the arm g¹ of the lever g as the other
arm g of which is pressed against the door post on the closing of same in the usual
manner.
Further, the strip a may be secured to the levers eel by rigid rods e²e as shown
by Fig. 10, and yet it may be allowed to descend by its own weight by arranging
the arm g of the lever g to press directly upon the spring p', and should its own
weight be insufficient to cause it to descend as quickly as desired a spiral spring s
might be secured to it and to the cover b in order to assist it in its said descent, but
in such case the spring p' has to be sufficiently strong to overcome the springs as
well as raise the several parts against the action of gravity.
This latter springs may also be employed in connection with arrangement of
parts shown by Figs. 1 and 2 if and whenever found necessary. Or again the
strip a may be suspended by the hooks t t¹ from the bar u which extends from the
arm v to the arm of the lever v, this said lever vand its bar u being acted upon
so as to maintain the strip a in its raised position by means of the spring w.
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. In combination with a weather bar or draught-excluder means for operating
same substantially as herein specified.

page_text: 2. The combination of the several parts for operating a weather bar the same
being formed and arranged substantially as herein set forth and described.
