COMPLETE SPECIFICATION.
Improved Apparatus for Excluding Draughts and the like.
I ARTHUR FENEMORE, of Sulgrave, Banbury, Northamptonshire, Joiner &
Builder, do hereby declare the nature of this invention and in what manner the
same is to performed, to be particularly described and ascertained in and by the
following statement :—
My invention relates to an improved apparatus for excluding draughts and the
like, and has for its object to provide an apparatus or device for the said purpose
that shall be automatic in its action, and effective in operation.
According to my invention the apparatus is fixed to the bottom of the door or
sash of window or convenient place as desired, by means of metal plates secured to
the edges or bottom corners of the same and let in flush, the said plates are slotted
in the middle at the lower end to receive the ends of a bar of metal which is let
into a groove formed in the bottom of the door or sash and held up by a spring or
springs attached to the before mentioned metal plates at one end and to the bar at
the other. The bar has one or more strips of india-rubber or other flexible
material secured to it in such a manner as to allow the lower edge or edges of same
to project below the door or sash when the latter is closed, so as to press upon the
sill or floor and prevent the passage of air, water or the like; but when the door
or sash is opened the india-rubber or other flexible material attached to the bar
recedes into the groove of the door or sash and allows the latter to swing freely...
To give a downward movement of the bar when at the instant of the closing of
the door, or sash, I make the ends of the bar to project a little. The one projection
is tapered at the top edge and comes in contact with a metal plate which is let in
and secured to the jamb of the door way or sash and presses or rubs along the
lower edge of same, so causing the bar to slide downwards a short distance. The
other end of the bar has a projection which carries a small friction-roller and
comes in contact with the sloping under-edge of another metal plate which is let
in and secured to the jamb of the doorway or sash, and presses the other end of the
bar downwards just as the door closes, both ends being operated simultaneously, so
closing the draught space beneath the door, or sash.
The india-rubber or other flexible material I attach to the bar of metal in such
a way that it may readily be removed when worn, by attaching washers or a metal
plate or plates, held and drawn together by screws or rivets and so compressing the
rubber to the metal bar, or it can be let down to suit any depth of aperture. The
lower edge can also be readily cut or fitted to any curve or irregularity in the sill
or floor and thus effectually prevent any draught or wet passing under, from the
rain or the like beating against it when closed.
And in order that my invention may be the more readily understood I have shown
same in the accompanying sheet of drawings, wherein :-
Fig. 1 represents the lower half of a door, with my improved apparatus attached,
and shown in dotted lines.
Fig. 2 is a front elevation of the plate which is fixed to the jamb or side of the
door-way on the hinge side, showing the projecting end of the bar coming in
contact with the lower edge of the plate.
Fig. 3 is a rear elevation of the said plate.
Fig. 4 is a front elevation of the apparatus complete.
Fig. 5 is a front elevation of the plate D and roller (Fig. 1).
Fig. 6 is an elevation of the second plate, which is secured to the foot of the
jamb of the doorway (for instance), the position of the roller and the rubber, when
the door is closed and anan haine alea chamn

page_text: Figs. 7 and 8 illustrate the modified apparatus as applied to folding windows or
doors.
Fig. 9 is a plan of the T-piece.
Fig. 10 is a perspective view of the apparatus as applied to a door, while
Fig. 11 shows the various methods I may employ of arranging and securing the
strips or strips of india-rubber or other flexible material to the bar.
A. are the coil or other springs for holding the bar E in position, one end of each
spring being attached to the said bar, whilst the other end is attached in like
manner to the projecting parts c, c¹ of the plates C and D.
These plates C and D are attached by screws or other suitable means, to the
edges or lower corners of the door or sash D₁, and let in flush with same.
Slots are formed in the said plates for the purpose of receiving the ends of the
bar E, which is let into a groove formed in the bottom of the door or sash D¹.
bis the strip of india-rubber or other flexible material secured to the bar E, in
such a manner as to allow the lower edge or edges of same to project below the
door or sash D' as shown.
The projecting portion E¹ of the bar E is tapered at the top edge as shown, and
comes into contact with the lower edge of the metal plate A, which plate is fixed
to the side of the jamb or side D¹ of the doorway (when the invention is applied
to doors) at such an elevation as will allow of any desired drop to the bar E,
according as the draught space under the door requires to be filled up. The other
end of the bar E has a projection which carries a small friction-roller r, and comes
in contact with the sloping under edge of another metal plate B which is fixed to
the jamb D of the doorway or sash, and so presses the other end of the bar E
downwards, at the moment of the closing of the door, both ends of the said bar
being operated simultaneously and so closing the draught space beneath the door
or sash.
A plate p, p, can be pressed on to the strip or strips of india-rubber or the like b,
and secured to the bar E by means of screws or the like.
The roller shown in dotted lines indicates the position it assumes when the
door for instance is closed.
The various methods of arranging and securing the strip or strips of india-rubber
or the like shown in Fig. 11 are sufficiently clear as not to call for any particular
explanation or reference to same.
My improved apparatus can also be fixed to folding doors or windows, in which
case I make another bar E2 (Fig. 7) of similar shape and dimensions to that first
described with rubber or other Hexible material attached as before, but the inner
end of this second bar E2 instead of having a roller attached, has a plate or
T-piece F fixed or forged on to same.
?'
The roller on the one part or bar E comes in contact with this plate or T-piece F
on its under side, and the bevilled edge of the fixed plate B on its top_side on the
other part so that as the roller is depressed it likewise depresses the T-piece F on
its under side. The two bars E, E2 with the rubber attachment 6 are operated and
worked simultaneously as before-mentioned to suit folding doors or windows and
the like.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In apparatus such as described, the use of a bar having a strip or strips of
suitable flexible material secured to same, the whole raised and lowered and
operated substantially as described and illustrated in the accompanying drawing.
2. In apparatus such as described the use of a bar provided with a flexible strip
or strips, in combination with coil or other springs for keeping such bar in position,
substantially as described and illustrated by the accompanying drawing.
3. In apparatus such as described, the use of a bar provided with a flexible strip
or strips and bevilled off at one end and provided with a friction roller at the other

page_text: in combination with coil or other springs and plates bevelled off to suit the depth
of fall of the bar, substantially as described and illustrated by the accompanying
drawing.
4. In apparatus such as above claimed, the use of second bar similar to the
first-described, provided with a T-piece at one end, substantially as and for the
purpose described and illustrated by the accompanying drawing.
Dated this 22nd day of October 1892.
