Improvements in Window Sashes, Shutters, Blinds, or Screens.
We, FEALDON WATTON, and JOSEPH DUNSFORD, both of Altamont,
Illinois, U.S.A. Gentlemen, do hereby declare the nature of this invention, and
n what manner the same is to be performed, to be particularly described and
scertained in and by the following statement :-
Our invention relates to a window-sash, shutter, blind, or screen, so constructed
that it may be adjusted to window-frames of different widths, and fit tightly
therein, and my invention consists in features of novelty hereinafter fully described
and pointed out in the claims.

improved sash in position in the frame
Fig. 2 is a detail side elevation, part broken away to show one of the plates.
Fig. 3 is a similar view in which but one plate is shown.
Fig. 4 is a cross-section taken on line e, Fig. 2.
Fig. 5 is a cross-section taken on line yy, Fig. 2.
Fig. 6 is a detail edge view of the upper end of the adjustable strip showing the
ends of the plates bent over upon the top of the adjustable strip.
Fig. 7 shows my invention applied to a window-shutter, and
Fig. 8 shows it applied to a window-screen.
Referring to the drawings 1 represents a window-sill, 2 the sides of the frame,
and 3 a window having the usual upper and lower bars 4 and 5 and side
bars 6 and 7.
Secured in the outer edge of the bar 7 are vertical plates 8 that extend beyond
the edge-bar 7, and are provided with slots 9.
10 is a bar or strip equal in length to the bar 7 and parallel therewith. The
bar has kerfs 12 in which the outer edges of the plates 8 work, and thus the
bar 10 is kept in the same plane as the sash, the bar 10 being secured to the
plates by pins.
Passing through the bar 10 are slots 9. The ends 13 and 14 of the plates 8 are
preferably bent over upon the upper and lower ends of the bars 7 and 10, as shown
in Fig. 6.
Coil-springs 15 are seated in the recess 16 in the upper and lower parts of the
bar 7, and said springs bear against the strip 10 and press outward. In order to
increase or diminish the power of the springs 15 their inner ends rest against the
inturned end 15° of the plate 15, the body of the plate occupying a recess in the
sash and admitting of endwise movement on set-screw 15° which passes through a
longitudinal slot 15d in the plate. Secured in the bar 10, near its upper and lower
ends are dowel-pins or screws 17, whose outer ends work in holes in the strip 10.
The dowel-pins or screws may, however, be made fast in either bar.
In Fig. 7 we have shown our invention applied to sliding shutters such as are
used in the windows of railway-cars and buildings.
In Fig. 8 we have shown our invention as applied to window-screens.
We have described our invention as having two plates 8 for connecting the
bar 7 and strip 10, but in light windows, shutters and screens, there may be but one
used as we have shown in Fig. 3.
The dowel-pins or screws 17 may be dispensed with in light work.
The side bars 6 and 10 of the window may have grooves 18, as usual, to work on
guide-ribs on the sides of the window-frame.
It will be seen that the sash, shutter, or screen will fit close in the frame, so that
no air or moisture can pass between the sash, etc., of the frame, nor between the
bars 7 and 10.

page_text: The device has also another valuable feature, in that it forms a support for the
sash, shutter, inside blind, or screen, by the bearing of the bar 10 against the
window-frame. For this reason balance weights with their cords and sheaves may
be dispensed with.
Still another advantage is found in the device-namely, that the sash admits of
such construction that it may be removed from the frame at any time by forcing
the bar 7 in contact with the bar 10. The operation of my device is as follows:
The parts being first connected as described, the bar 10 is set into the usual groove
in the window-frames, and the sash grasped by the bar 6 and pressed toward the
bar 10, causing the coiled-spring 15 to contract and allow the bar 7 to be pressed
in contact with the bar 10. When the parts are thus contracted the bar 6 may be
placed in position in its groove in the frame or the screw 15 adjusted so the
guide-strips rest in the grooves 18, and the bar 10 allowed to move outward, and
thus the bars 6 and 10 are held tight against the window-frame.
By constructing a window-sash, blind, or screen according to my invention, it
may be placed at any desired elevation, and will remain in that position
without the use of weights or cords. It may also be easily moved into any other
position.
The device also provides a tight connection between the sash and window-frame,
whereby dust, etc., is prevented from entering, and should the sash or frame
become shrunk or swelled from heat or rain the sash adjusts itself to the changed
conditions.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that
what we claim is :
1. The combination, in a window-sash, blind, or screen, of the bar 7, plates 8, and
bar 10, suitably connected to the plates with springs forcing the bar 10 outward,
substantially as and for the purposes set forth.
2. The combination, in a window-sash, blind, or screen, of the bar 7, plates 8,
secured therein, and a bar 10 adjustably connected to the plates by a pin passing
therethrough, and working in slots in the plates, substantially as and for the
purpose set forth.
3. The combination, in a window-sash, blind, or screen, of the bar 7, plates 8,
secured therein, bar 10, connected to the plates 8 by pins 11 working in the slots 9
of the plates, and a spring 15, substantially as and for the purpose set forth.
4. The combination, with a window-sash, blind, or screen, of a side bar 10,
plate 8, forming a guide for the bar 10, and spring forcing the bar outward,
substantially as set forth.
5. The combination, with a window-sash, blind, or screen; of the plate 8, bar 10,
spring 15, and the movable plate 15, forming a bearing for the inner end of the
spring, substantially as set forth.
