PROVISIONAL SPECIFICATION.
Improved Means for Attachment to Doors and French Windows and
their Frames in order to Prevent Draughts and Exclude Dust.
I, JAMES HOLGATE, of 14 Upper Cleminson Street, Salford, in County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improved means for attachment to doors and French
windows and their frames in order to prevent draughts and also to exclude dust
snow rain etc.
In carrying my invention into effect I attach to the top and sides of the frame of
each door or window plates of metal or other suitable material. Each plate is
hinged screwed or otherwise suitably connected along one edge to the frame and
is so mounted that it will be pressed against the top or sides of the door or window
when closed.
This may be effected in the case of the side plates by springs and in the case of
the top plate by gravity or each plate may form its own spring.
I also hinge or otherwise attach to the bottom of the door or window a plate
which is raised automatically by means of an incline or projection and latched in
position by a catch when the door is opened and when the door is closed the catch
comes in contact with a projection and is thereby disengaged thus allowing the bottom
plate to rest upon the floor or carpet or other floor covering.
The plates may be fixed to the frame all round the door or window or to the top
or bottom or side only or any two or more in combination, and in some cases it
might be more convenient to connect the plates to the door or window in place of to
the frame.

COMPLETE SPECIFICATION.
Improved Means for Attachment to Doors and French Windows and
their Frames in order to Prevent Draughts and Exclude Dust.
I, JAMES HOLGATE, of 14 Upper Cleminson Street, Salford, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention and in
what manner the same is performed, to be particularly described and ascertained
in and by following statement:-
My invention relates to improved means for attachment to doors and French
windows and their frames in order to prevent draughts and also to exclude dust
snow rain etc.
In carrying my invention into effect I attach to the top and sides of the frame of
each door or window plates of metal or other suitable material. Each plate is
hinged screwed or otherwise suitably connected along one edge to the frame and is
so mounted that it will be pressed against the top or sides of the door or window
when closed.
This may be effected in the case of the side plates by springs and in the case of
the top plate by gravity or each plate may form its own spring.
I also hinge or otherwise attach to the bottom of the door or window a plate
which is raised automatically by means of an incline or projection and latched in
position by a catch when the door is opened and when the door is closed the catch

Referring to the sheet of drawings forming part of this Specification
:―
Figure 1 is an elevation of a door fitted with draught and dust excluding plates
according to my invention.
Fig. 2 is a horizontal section of the door showing the side plates.
Fig. 3 is a vertical section of the door showing the top and bottom plates.
Fig. 4 is a vertical section of the door showing the bottom plate raised.
Figs. 5 and 6 are details of the bottom plate.
Fig. 7 is a detail of the top plate and-
Fig. 8 a detail of one of the side plates.
Fig. 9 is a view of the lower part of the door showing the bottom plate fitted in
the reverse way to that illustrated by Figs. 3 and 4.
In these views, (a) designates the door, (6) the frame, (c) (c) side plates, (d) the
top plate, and (e) the bottom plate. The side plate (c) and the top plate (d) are
shown attached to the frame by small screws (f) which pass loosely through holes
in the plates so as to allow the plates a certain limited movement.
The top plate (d) as shown in Fig. 7, falls by its own weight upon the top of the
door, when the latter is closed, but the side plates (c) are pressed into contact
with the door as shown best in Fig. 8, by means of a series of spiral
springs (9) which are fitted in recesses in the frame (b) at the back of the
side plates (c).
The bottom plate (e) is bent round the lower edge of the door (a) on either the
inside or outside and attached thereto by screws (f) in a manner similar to that
described with reference to the top and side plates.
When the door is open the bottom plate (e) is held up by a catch (h) which is
pivoted to the door and engages a hook (e¹) on the bottom plate (e). As the door
is closed the hook (e') is released from the catch (4) by a pin or projection (i) fixed
in the frame or jamb of the door and with which the catch comes in contact; as soon
as the catch is disengaged the bottom plate (e) falls by its own weight into the
position shown best in Fig. 5.
As the door is opened the plate (e) passes over an incline (k) by which it is raised
and then latched in position by the catch (h) engaging the hook (e).
The plates may be. fixed to the frame all round the door or window or to the top
or bottom or side only or any two or more in combination, and in some cases it
might be more convenient to connect the plates to the door or window in place of
to the frame.
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. The combination with a door or French window, of a plate or two or more
plates in combination arranged to close the spaces between the door or window
and its frame substantially in the manner herein set forth for the purpose
specified.
2. The general arrangements and combinations of parts constituting improved
means for attachment to doors and French windows for the purpose of excluding
draughts and dust etc., substantially as herein described with reference to the
accompanying drawings.
