page_text: I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.
do hereby declare the nature of this invention to be as follows:-
This invention relates to screen doors and has for its object to provide means by
which they can be easily and quickly converted into storm doors, which object is
accomplished by the construction and combination of parts as will be hereinafter
more fully described.
Referring to the accompanying drawings in which like letters of reference indicate
like parts,
Fig. 1 is an elevation of the inside of a screen door which is provided with three
forms of these improved storm-door panels.
Fig. 2 is an elevation of the outside of the same door, which is provided with
two forms of these improved panels.
Fig. 3 is a longitudinal vertical sectional view taken on line x-x figure 1.
Fig. 4 is a transverse sectional view taken on line y-y figure 1 ; and
Fig. 5 is a similar view taken on line 2-z, figure 1.
A indicates the frame of a screen door and B indicates the wire covering screen
which covers the spaces into which the said frame is divided as shown, by its middle
rail A and. mullion A. Both sides of the middle rail and the mullion A² 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 improved storm panels being placed upon
that side of the frame. Secured upon the other side of the rails and mullions of the
frame are the strips of molding D the strips upon the outer rails being formed with a
groove E upon the under side of their inner edges while those upon the middle rail
and mullion are provided with a similar groove upon both edges. These strips of

page_text: molding thus form a frame upon the screen door frame as shown in figure 2 by means
of which storm-panels can be secured upon that side of the screen door frame as well
as upon the other side. The molding can be placed at a little distance (one quarter
of an inch or more) from the edges of the frame bordering the spaces so as to form
the jamb b against which the storm-panels will rest when the grooves upon the under
side of the molding will form the jamb as shown in figures 4 and 5. These storm-
panels may be constructed in either of the three forms here shown-that is, the panel
may be formed in two longitudinal sections F F which are hinged together at their
inner edges, and one of the said sections being provided at its inner edge on the outer
edges thereof with a strip F2 which will extend over the joint at the said inner edges
when the panel is in its operative position and thus render the panel perfectly water
and storm proof one of the sections having a catch G and the other a latch H by
means of which the panel is locked or held in its flat operative position as shown in
figures 1 and 4 or the panel may be constructed of two sections which are a little
wider when placed side by side than the inside width of the frame space in which they
are inserted so that the inner edges of the two sections I J will overlap to render
them storm tight; and these two sections are connected by a toggle joint K or by
two or more of the said joints which secures the panels adjustably together and also
provides a means whereby they can be conveniently and readily spread apart; and
a thumb nut at the centre of each toggle joint furnishes a means by which they can
be held in position after being spread apart, as the thumb nut can be tightened to
bind the toggle arms in their adjusted position; or the panel can be formed in a
single piece L of sufficient thinness to admit of its ends or edges being sprung
into the grooves of the molding.
L
Another form of panel (shown at M) may also be employed which consists merely
of the two sections M M² the inner edge of one of which is provided with a strip M³
which overlaps the joint and thus makes the panel perfectly storm tight one of the
parts being provided with a latch N and the other with a catch O by means of which
the panel is locked or held in its flat operative position. These panel-sections are
preferably made a little longer than the inside length of the frame-space in which
they fit, and are then constructed of thin material so that they can be sprung into
their end positions as will be readily understood.
It will be seen that the grooves are formed on both sides of the wire screens in the
frame spaces and the storm panels are placed in position with their edges in these
grooves on both sides of the said screens thus rendering the screen door perfectly
storm-tight on both sides and perfectly protecting the screens.
The edges of the panels may be secured beneath nails or screws Q if desired, thus
dispensing with the grooves but it is preferable to form the door with the grooves as
when the edges of the storm doors have been sprung or fitted into the said grooves
a perfectly water-tight joint is formed by the said edges and the grooved moldings
in which they fit which is far more effective than merely engaging the edges of the
panels under nails or screws as shown at Q.
From the foregoing description taken in connection with the accompanying
drawings the construction and advantages of this invention will be readily understood.
It will be seen that the storm panels can be placed and secured in their operative
positions in the grooves of the moldings in a few moments and that when thus placed
they will transform the screen door into an exceedingly effective storm-door protected
on both its outside and inside by the storm-panels the wire screens being thus
effectively protected.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondent and in what manner the same
is to be performed to be particularly described and ascertained in and by the following
statement :-
1. The combination with the frame of the screen-door of a removable panel secured
thereto said panel being composed of two pieces said pieces being adjustably secured
together at their imiddle portions as shown and described.

page_text: 2. The combination with the frame of a screen-door of a removable panel secured
thereto said panel being composed of two pieces which together are wider than the
inside width of the frame and overlap each other at their middle portion and a toggle-
joint having a thumb nut at its centre securing said two pieces together at their top
and at their bottom as shown and described.
3. The combination with a screen-door frame adapted to receive storm-panels upon
one side, of strips of grooved molding secured upon the other side of said frame
corresponding with the rails and mullions of said frame and storm-door panels secured
within said grooves substantially as and for the purpose shown and set forth.
