This my invention relates to an improved screen door and its object is to
construct a door for temporary use which may be readily put together and taken
apart when required.
My improved door consists of a frame provided with detachable cross strips and
vertical strips and formed to receive panels upon one side. Movable rails and
mullious are placed upon the opposite sides of the said panels the positions of the
said rails and mullions corresponding with the cross and vertical strips of the door
frame, the several parts being secured together by means of suitable clamps or
other devices.

COMPLETE SPECIFICATION.
An Improved Screen-door.
I WILLIAM WILSON HORN of the firm of Horn & Son of 151 Strand in the
County of Middlesex Patent Agent do hereby declare the nature of this invention
(a communication to be from William R. Lyle of Ripon in the State of Wisconsin
United States of America, Inventor, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of the present invention is to simplify the construction and provide a
screen-door which can be readily converted into a storm door and which may be
furnished at but a comparatively small expense over the ordinary screen-doors
in common use.
The invention consists in the combination, with a screen-door frame adapted to
receive storm-panels upon one side, of strips of molding corresponding with the
rails and mullions of the frame and interlocking with each other and with the inner
sides of the frame as hereinafter more fully described.
In the accompanying drawings,
Fig. 1 is an elevation of the inside of a screen-door which is provided with my
improvements.
Fig. 2 is a longitudinal vertical section taken on the line a Fig. 1.
In the said drawings, the reference numeral 1 indicates the frame of a screen-door
and 2 indicates the wire-covering-screen which covers the spaces into which said
frame is divided, as shown by its middle rail 3 and mullions 4. Both sides of the
middle rail and the mullions may be formed or provided with grooves on their
under edges, as also the inner sides of the side rails of the frame, to permit of the
storm-panels being placed upon that side of the frame.
Secured upon the other side of the screen frame are the strips of molding 5,
which are preferably provided with grooves 6 to receive the outer edges of the
panels. They may however be made without grooves or plain if desired.

page_text: The numerals 7 and 8 designate the removable interlocking retaining strips by
means of which the panels are retained in place.
7 designates the cross strip and 88 the vertical strips, corresponding to the cross-
rails and mullions of the screen-frame. These strips. may be grooved to receive
the edges of the panels, or they may be made plain or without grooves, as desired
they performing their function equally well in either case. At the centre of the
cross-rail upon each side is a projection or lug 9, which fits over the inner end
of each vertical strip 8, which is recessed or cut away at 10 for such purpose,
whereby said strips 8 are secured in place. The outer ends of the cross and
vertical strips are held in place by means of turn-buttons or wires 11, secured to
the screen frame and capable of being turned in and out of contact with said strips
so as to hold or release them.
It is obvious that instead of the lug 9 I may recess the under side of the cross-
strip and cut away the end of the vertical strips so as to enter and be held in said
recesses.
From the above description the manner of applying my invention will be
readily understood. When it is desired to convert the screen-door into a storm-
door, the cross strip 7 and the vertical strips 88 are removed and the panels 12,
which are preferably composed of some thin pliable material, so that the ends may
be sprung into the grooves, are placed upon the wire-screen with their outer edges
resting in the grooves 6 of the molding 5. The cross strip 7 is then inserted in
position. The vertical strips are then introduced.
As before stated the cross and
vertical strips may be grooved to receive the edges of the panels or they may be
made plain as may be found most convenient or desirable.
The advantages of the invention will be readily understood. It will be seen that
the storm panels can be inserted and secured in position in a few moments, and will
thus transform the screen-door into a storm door effectually preventing the entrance
of rain, wind, or snow, and at the same time will protect the screen from injury
or damage.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what.I
claim is
1. The combination with a screen-door frame provided with detachable cross-
strips and vertical strips and adapted to receive storm-panels upon one side, of the
rails and mullions upon the opposite side corresponding with the strips, said strips
interlocking with each other and with the door frame substantially as and for the
purposes set forth.
2. The combination with a screen-door frame & panels, of the cross-strip 7
having lugs 9, the vertical strips 8 8, and fastening device 11 for removably
securing said strip to the screen-frames substantially as described.
