Complete Specification Left, 10th Dec., 1894-Accepted, 12th Jan., 1895
I, CHARLES COOK WHEELER of Marysville, County of Marshall, Kansas,
United States of America, Manufacturer do hereby declare the nature of this
invention to be as follows:-
The window screen of this invention comprises a frame across which the screen
material, wire gauze for instance, is stretched and fixed. On one of the vertical
sides of the screen frame there is a movable section extending along its outer edge
from top to bottom and which may, by means of thumb screws carried in the frame,
be moved outwards or inwards so as to be made to fit the window frame. In this
way the screen may effect a tight closure in front of an open window whilst the
window may be raised or lowered at pleasure, or the screen may by means of the
thumb screws and movable section or fillet be fixed immediately underneath
the open window sash. A thin lip is fixed to the frame to overlap the joint between
the stationary and movable frame sections.
Dated this 10th day of March 1893.

I, CHARLES COOK WHEELER of Marysville, County of Marshall, Kansas,
United States of America, Manufacturer, 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 :-
The improved window screen of this invention is shewn in the accompanying
drawing, in which
Fig. 1 is a view of the screen adjusted within a window frame in front of the
plane in which the window sash moves up and down.
Fig. 2 a section through line x-x of Fig. 1.
Fig. 3 a view of the screen in detail, the side provided with the movable sash
section being shewn in section to disclose the adjusting devices and their connections
with both the movable and fixed sash sections.
A is the window sill, a the side frames of the window and B the lower portion of
the window sash within the frame. C, C¹, are the sides and C2, C3, the top and
bottom of the rectangular screen which inay be provided with wire gauze stretched
TD 021

page_text: across it and permanently fixed thereto, as is usual. One side of the screen frame,
in the present instance, the side C is provided with a movable section c extending
along its outer edge from top to bottom. The movable section c is fitted to slide
easily between two lips D, D₁, which are fixed at one edge to the outer opposite
edges of the side of the window sash and project thence outwardly parallel with
each other. The lips may be formed of any suitable material-sheet brass for
instance the opposite edges of the the screen frame part C being recessed so that
the lips come flush therewith. E, E, are thumb screws extending through the
side C and engaging in threaded sockets or nuts e, e', fixed in the outer edge of
side C. Said thumb screws are provided with shoulders e² at a short distance from
their points which shoulders are adapted to engage bearing plates F, F¹, fixed to
the inner edge of the movable strip c, whilst the points of the screws extend
through perforations or into recesses in the bearing plates and are there held by
cross pins or by upsetting their ends or by any other suitable and known means so
that they cannot be withdrawn from said plate but may readily be rotated.
To adjust the screen to the window frame, it may be placed within the frame in
proximity to the path along which the window sash slides, and by turning the
thumb screws, the movable section may be forced outwardly between the
lips D, D', until the screen frame presses against the opposite sides of the window
frame. As the face of the screen frame towards the window sash is flush with the
inner lip D¹ (when such inner lip is employed) the screen will form a tight closure
.in front of the open window whilst the window may be raised and lowered at
pleasure without removing the screen, if so desired, also the screen may be placed
beneath the window sash and adjusted in a like manner.
The screen is adapted for use in connection with horizontally sliding as well
as with vertically sliding windows and may be manipulated with the greatest ease.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A window screen comprising a frame across which the screen material is stretched,
a movable frame section extending along one side of the screen frame, screws
engaged in screw threaded nuts or sockets in the fixed side of the frame and locked
to said movable frame section so as to turn freely and move the movable section
towards or away from the fixed section and a lip fixed to the stationary frame
and overlapping the joint between the fixed and movable frame sections,
substantially as described and shewn.
Dated this 10th day of December 1894.
