Improvements in Automatically-operating Bars Applicable to
Doors or Hinged Windows for Excluding Cold Air, Rain, or
the like.
We RICHARD HOLMES of 32 Park Lane, and BENJAMIN SUGDEN of 10 Temple
Row, both in Keighley, Yorkshire, Joiners and Builders, do hereby declare the nature
of this invention to be as follows, that is to say :-
It has for its object the prevention of cold air, rain or the like, from entering or
passing under doors or hinged windows through the openings that almost invariably
exist between the bottom edges of same and the ground or wall beneath.
This we accomplish by mounting a bar to the bottom part of said door or window
in such a manner that when said door or window is closed said bar is pressed down-
wards to cover the opening at the bottom thereof, while when said door or window
is being opened said bar rises to allow said action of opening; both movements of
said bar being performed automatically.
The above named bar is of suitable dimensions and is mounted in a groove formed
either in the bottom edge of the door itself or by mounting a suitably shaped piece
thereto. Attached to the said bar are springs, which, when permitted, keep it in its
raised position. Also attached to the upper edge of said bar is a suitable number of
taper or wedge shaped pieces which, when the said bar is in its raised position, enter
suitably shaped recesses formed in the upper edge of the groove, and when said bar
is in this position, its outer end, on that side of the door or window by which said
door or window is hinged, projects a suitable distance therefrom.
As will be seen the door or window is open when the several parts are in their
respective positions above named, and as the door or window is being closed, by the
outer end of the bar coming in contact with the door's or window's post it is pressed
horizontally, but by the wedge shaped pieces pressing against the edges of their
respective recesses it will be seen that the bar will be pressed downwards.

page_text: We preferably construct the wedge shaped pieces of metal and we also preferably
cover the surfaces of the recesses that are in contact with these said pieces, with strips
of metal, as also the outer end of the bar that is brought into contact with the door's
or window's post..
The springs are preferably placed about parallel with the sloping edges of the
wedge shaped pieces so as to operate more advantageously than if placed otherwise.
The part that is attached to form the groove at the bottom of the door, if placed
on the outside thereof is made to project in a suitable manner so as to prevent
rain or water from spreading over said door by being forced upwards with the
wind.

page_text: Improvements in Automatically-operating-bars Applicable to
Doors or Hinged Windows for Excluding Cold Air, Rain, or
the like.
We, RICHARD HOLMES of 32 Park Lane and BENJAMIN SUGDEN of 10 Temple Row,
both in Keighley in the County of York, Joiners and Builders 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 prevention of cold air rain or the like from entering or
passing under doors or hinged windows, through the openings that almost invariably
exist between the bottom edges of same and the ground or wall beneath.
Such being the nature and object of our said invention we will proceed to describe
same, reference being had to the accompanying sheet of drawings illustrative thereof.
Fig. 1 is front view of the bottom portion of a door with our improved appliance
attached thereto (since a hinged window-operates in a similar manner to a door this
invention is described in connection with the latter, and it will readily be understood
how it may be applied to the former). Fig. 2 illustrates the improved appliance, the
door and adjoining posts being shewn in broken lines.
Fig. 3 is a sectional plan shewing the door partly opened. Fig. 4 is a sectiona.
side view of fig. 1. Figs. 5 and 6 are similar views to Fig 2, but illustrate modifi-
cations. Fig. 7 is a side sectional view of fig. 5.
Similar letters and figures of reference indicate similar parts, throughout the
several views.
The object above set forth is attained by mounting a bar a to the bottom part of
the door b, in such a manner that when said door bis closed said bar a is pressed
downwards to cover the opening at the bottom thereof, while when said door bis being
opened said bar a rises to allow said action of opening, both movements of said bar a
being performed automatically.
The bar a is of suitable dimensions and is mounted in a groove formed either in
the bottom edge of the door 6 or by mounting a suitably shaped piece or cover d
thereto.
Attached to the bar a are springs ee which when permitted keep said bar a in its
raised position.
Mounted on the upper edge of the bar a is a suitable number of taper or wedge
shaped pieces ff which, when said bar a is in its raised position, enter suitably shaped
recesses g g, and when said bar a is in this position its outer end a' on that side of
the door b by which said door bis hinged, projects a suitable distance therefrom as
shewn by fig. 3.
As will be seen the door is open when the bar a is in the position above described,
and as said door bis being closed, by the outer end a¹ of the bar a coming in contact

page_text: with the door-post h said bar a is pressed in a horizontal direction, which pressure by
the action of the pieces ff upon the inclined edges of the recesses g g, forces the
bar a downwards.
The springs e e are preferably placed about parallel with the sloping edges of the
pieces ff so as to operate more freely.
a,
in
Instead of mounting the pieces ff upon the bar a as shewn by fig. 2, we might
mount them on a separate bar k, see fig. 5, and form the recesses 9 g in the bar.
this case a pin is necessary to prevent any lateral movement of said bar a. To assist
the bar at the commencement of its return movement when the door is being
opened a small spring m is placed to press upón it at its outer end as will readily
be understood.
When the above named arrangement of moveable bar. k is employed the pieces ff
may be substituted by the bell cranked levers nn. These levers n.n being mounted
on the door and made to operate by projections on the bark coming into contact
with them.
.
We preferably construct the pieces ff of metal, and we also preferably. cover. the
surfaces of the recesses g g that are in contact with these said pieces ff, with strips
of metal as also the outer end a¹ of the bar a that is brought into contact with the
door's post h.
The part d has its bottom edge formed at a suitable angle to the face of the door
so that water, as rain &c. falling on said door may more readily leave same to pass to
the ground beneath.
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 bar a, the pieces ff operating within recesses g g, and the springs e e in
combination, substantially as and for the purposes specified.
2. The bar a having recesses g g formed in it, the pieces ff, the bar k, the pin
and the springs ee and m in combination substantially as and for the purposes
specified.
