PROVISIONAL SPECIFICATION.
Improvements in Weather Bars or Draught Excluders for Doors,
Hinged Windows, or the like.
I, THOMAS GREEN of Farnhill, Kildwick near Keighley in the County of York,
Joiner and Builder, do hereby declare the nature of this invention to be as follows,
that is to say :-
In accordance with my invention I make use of the well known sliding bar and
strip of wood or other material operated thereby, however instead of employing
compound levers or levers and connecting links for coupling the one to the other
I arrange and form simple levers to effect the result desired, thus on the one hand
while I attain the freedom of action secured by lever mechanism as compared with
that produced by the employment of inclines or cams on the other 1 avoid the
disadvantages of having too many pivotal attachments as is the case when
compound levers are used.
The simple levers which I employ are somewhat of bell crank shape and are
otherwise formed so that their upper ends may be pivotally attached to the bearing
piece while their lower extremities reach into contact with the strip of wood used
for covering the opening at the bottom of the door or hinged window to which it
is applied, and the sliding bar operated in one direction on the closing of the door
by its pressure against said door's jamb, against the pressure of a spring which by
its resilience effects the return movement of this bar on the door being opened, is
arranged to intervene between the bearing piece and the upper edge of the strip
of wood.
The sliding bar is retained in its horizontal path of motion by lateral projecting
pieces formed on slotted guides in the slots of which operate pins carried by the
moving strip, the pivotal openings by which the simple levers are attached to their
bearings are made slightly of elongated form to allow this bar to slide freely on its
bearings.
The sliding bar is attached by suitable pivotal attachments to the pendent or
simple levers above described, while these latter have slots formed in them to
take over pins fixed in the moving strip so that as the sliding bar is operated
these pendent levers are oscillated and by pressing against the pins in their slots
impart motion to the strip which motion on account of the slotted guides preventing
it from being in any but a vertical direction, is as desired and is considerably in
excess of that of the sliding bar.

I, THOMAS GREEN of Farnhill, Kildwick near Keighley in the County of York,
Joiner and Builder, 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 :-
In accordance with my invention I make use of the well known sliding bar and
strip of wood or other material operated thereby, however instead of employing
compound levers or levers and connecting links for coupling the one to the other
I arrange and form simple levers to effect the result desired, thus on the one hand
while I attain the freedom of action secured by lever mechanism as compared with
that produced by the employment of inclines or cams, on the other hand I avoid
the disadvantages of having too many pivotal attachments as is the case when
compound levers are used.
In the accompanying sheets of drawings which are illustrative of my
invention;-
Fig. 1 is front elevation of a portion of a door and parts surrounding it and
shows the application of my improved bar.
Fig. 2 is a sectional view of same as seen from above, the door being shown as
partly open.
Fig. 3 is a view of the bar and its several parts drawn to an enlarged scale,
and shows same as when retracted or raised by the spring.
Fig. 4 is a similar view to Fig. 3, but shows the bar in its lowest position.
Figs. 5 and 6 are sectional elevations of parts shown by Figs. 3 and 4
respectively.
Fig. 7 is a drawing in detail (further enlarged) of a part hereinafter explained.
The bar a, strip of wood b and the covering piece c by which they are mounted
to the door d, are all of the well known kind.
The simple levers ff1 which I employ are somewhat of bell crank shape as
shown and they are so formed that their upper ends may be pivotally attached
at g g to the piece c, while their lower extremities reach into contact with the strip
of wood b which covers the opening at the bottom of the door, hinged window or
the like to which it is applied, and the sliding bar a, operated in the direction
indicated by the arrow a on the closing of the door d, by being pressed thereby
against the door's jamb hits return movement being effected by the spring k on
the door being opened; is arranged to intervene between the piece c and the upper
edge of the strip b.
The sliding bar a is retained in its horizontal path of motion by lateral
projections m³ formed on the slotted guides m m', in the slots f2 of which, operate
pins tt, secured to and carried by the strip b, and the pivotal openings by which
the levers fare with the pins or screws 9 9' attached to said bar c, are made
slightly of elongated form to allow this bar to slide freely in its horizontal path on
its bearings m².
The sliding bar a is attached by the pivotal screws ss as described, to the
levers ff, while these latter have slots n n¹ formed in them to take over pins or
screws pp fixed in the strip b so that as the bar a is operated backward and
forward these levers ff' are oscillated and by pressing against the pins or
screws p p in their slots n n', impart motion to the strip b, this motion being on
account of its pins t¹ operating in slots f of the guides m m³, in a vertical
direction as desired and is considerably in excess of that (the motion) of the
bar a.

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 I
claim is ;-
1. The combination with a sliding bar and strip of wood forming a weather bar
or draught excluder, of simple levers and guide pieces arranged in connection with
same substantially as herein specified.
2. The combination with the parts forming a weather bar or draught excluder
of the several levers and parts for operating and guiding same substantially as.
set forth.
