Improvements in the Construction of Screens for Windows.
I, ALFRED LINCOLN STREETER, Manufacturer, of 71 North Main Street,
Mansfield, in the County of Richland and State of Ohio, United States of America,
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 :-
In the drawings:
:-
Figure 1 is a perspective view with part of wooden frame broken away.
Figure 2 is a detached perspective view of roller cover with spring flaps F' to
secure said cover to frame of window.
Figure 3 is a section on line of roller and cover.
Figure 4 is a sectional plan showing method of guiding screen by the metallic
strips secured to the frame of window.
Figure 5 is a detached perspective view of roller and screen.
Figure 6 is a detached view of roller with adjustable end taken off.
Figure 7 is a perspective view of side guides.
Figure 8 is a sectional view of the end of spring roller.
Figure 9 is a perspective view of modified form of casing and cap.
A represents the window frame. B is the guide (see Fig. 7) secured to the
frame on each side of the window, said guide being provided with orifices
for
the purpose of securing said guide to the window. This guide may be constructed
of two pieces of metal 62 63 bent as shown in Fig. 7 and secured together so as to
leave the aperture d¹ between them; or the guide may be formed of a single piece
of metal bent as shown in Fig. 7 so as to leave the aperture 6. This guide is
secured to the window frame upon each side of the window. C is the screen roller
which is constructed in the two parts C e' (Fig. 6), the portion c¹ having portion
cut away and adapted to slide in the remainder of the roller, as shown in Fig. 5, so
that the length of said roller may be increased or decreased. One end of said
roller is hollowed and the spring roller D set in said hollowed end, as shown in
Fig. 8, and one end of the spring d of said spring roller D is secured to the screen
roller C. d is a metallic end of said screen roller C. E is the roller cover made
in sections and having the slot d for the screen to pass through, as shown in Fig. 2,
within which the screen roller C is placed, and the caps E' E' are put on the ends
of said cover.
The shaft d' of the spring roller D projects through the orifice e in
the cap and rests in the notch fin the flap F secured to the window frame. The
cap E rests against the spring flap F', so that when said screen roller C is in
position it is securely held. G is the screen made of woven wire net or any fabric
or material desired. One end of said screen is connected to the screen roller C,
the other end to the strip J, which strip is provided with orifices j¹³j³ for the
purpose of securing the said strip to the window, as shown in Fig. 1.
When the screen, etc., are in operation, they are in the position shown in Fig. 1,
when the upward movement of the window causes the screen to rise, and it is
guided by the strip and screen, travelling in the aperture 6 in the guide B. When
the window is lowered the spring roller D returns the screen as the window is
lowered. These attachments can with equal facility be made to the upper window,
but in the reverse manner, so that the downward movement of the upper window H
unwinds the screen and when the window is pushed up the spring roller rewinds the
screen as said window is pushed.
In operating, before putting the screen in position, it may be necessary to wind
the spring d, in which case it can be accomplished either by turning cap E¹ after

page_text: may
the spring and screen roller are in position in the cover, or the cap E¹ be made
in two portions E¹ and E' (Fig. 9), the outer end of portion E* being provided with
notched teeth e, and the other portion Es being provided with the pawl e adapted
to rest in said notched teeth e, the ratchet wheel E' being secured to the shaft of
spring roller, the spring shaft being provided with stem e adapted to receive a key,
or handle for the purpose of winding up the said spring and the spring may be
wound either by inserting a key on the said stem or by turning the ratchet by a
handle applied to the part . In either case the pawl e retains the spring.
When it is desired to change the shade and attachment to windows of a different
size, the telescopic character of screen roller and cover (as shown clearly in Fig. 2)
enables the screen roller and cover to be adjusted for any sized window by pushing
together, or drawing apart the parts M. M., so that if the screen and strip J be
made of proper size, then the remaining attachments can be used for any sized
window.
Having now fully 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 :-
1. A screen roller made in sections, one section adapted to slide over or into
the other.
2. A telescopic screen roller.
3. The telescopic screen roller illustrated in Fig. 6.
4. A cover for a screen roller made in sections, one section adapted to slide over
or into the other.
5. A telescopic cover for a screen roller.
6. The telescopic cover for screen rollers illustrated in Fig. 6.
7. A guide strip formed with a groove substantially as described and adapted to
be secured to window frame.
8. The guide strip illustrated in Fig. 7 formed from one or more pieces of metal.
9. A. screen secured to a strip as J adapted to be secured to the sash of the
window.
10. In combination, a screen, a screen roller, spring flaps secured to the frame of
the window adjacent to each end of said roller and adapted to press against said
roller and retain it in place.
11. In combination, a screen, a screen roller, a cover for said roller, spring flaps
secured to the frame of the window adjacent to each end of the roller and adapted
to press against said cover and retain it and the roller in position.
12. In combination, a screen, a screen roller, a strip as J connected with said
shade and adapted to be secured to the sash of said window, and guides as B on
each side of and secured to the frame of the window, in which the strip J and screen
are adapted to be guided.
13. The spring flaps, F and F', illustrated at Fig. 2.
the
14. The spring roller D with cap E' made in two portions as E and E³,
portion E provided with a ratchet and portion E' with pawl with or without the
handle e*.
15. The spring roller D provided with a stem adapted to receive a key.
