5 Claims. (Cl. 292-288)
My invention relates to a novel fastening and
designed to secure window screens against un
from strong spring wire and is substantially of
the shape shown in Fig. '7. It may be mounted
for axial rotation on the` plate ¿i by any suit
authorized opening from the outside.

Referring to the fastening device itself, I have
40 shown (Figs. 3 to 7) a very simple fastener having
first turned into the position shown in Fig. 4, i. e.,
the unlocked position in which the latch member
ii and the handle are substantially in the plane
of the plate. The fastener is then inserted be
tween the upper sash and the frame of the screen
so that the projection 5 abuts the lower edge of
the sash. Then the handle is moved into the
notch 9, bringing the latch member 6 into lock
ing position as shown in Fig. 2.

I claim:
1. A device of the class described comprising a 45
plate portion, an integral projection extending
away therefrom at substantially a right angle.
To give this projection the necessary rigidity, I
have formed ñanges 8 along its sides. These
50 flanges are wider at the apex of the triangular
portion than they are adjacent to the plate mem
ber, and a notch 9 is formed at the apex of the
member 6, the purpose of which will be more

ends thereof and apertures at the ends of said 50
channel, a locking member of substantially uni

The locking member 6 is preferably formed
rotatable in said channel and having one end 55

locking member being axially rotatable in said
a position in the plane of said plate to a position
at an angle thereto for cooperating with the pro
jection on the plate as described and stop means
integral with said device and disposed on the other
side of the plane of said projection from said
plate, said means adapted to engage said end of
said locking member for limiting rotatable move
ment thereof.
2. A device of the class described comprising a
channel and having one end bent substantially
at right angles to the main part thereof and the
other end bent at substantially a right angle in
the opposite direction and extending beyond the
projection to move the first end into locking po
sition at an angle to the plane of said plate, and
a detent provided by said projection adapted to
engage the adjacent end of said locking member
to prevent rotation thereof from the locking end.

4. A device of the class described comprising a
plate part, a laterally-projecting means near one

angles thereto, said plate having a channel ex
tending for a part of the distance between the
ends thereof and apertures at the ends of said
channel, a locking member of substantially uni
form cross-section having a portion of its length
located in said channel and extending through
said apertures, said locking member being axi
ally rotatable in said channel and having one end
bent substantially at right angles to the main
part thereof and the other end bent at substan~
tially a right angle in the opposite direction and
extending beyond the projection on said plate
whereby it may be manipulated to move the íirst
end for the purpose described and ear-shaped el»
ements integral with said plate and disposed on
the other side of the plane of said projection
from said plate thereby acting as a means for
limiting rotatable movement of said last men

3. A device of the class described comprising a
plate portion, an integral projection extending
end of said plate, said laterally-projecting means
extending from one side only of said plate, and 15
a locking member to secure another member
against movement in one direction relative to
the support, said locking member being movably
attached to said plate and having a part oper
able to extend away from said plate for cooper 20
ating with said laterally-projecting means, and
said laterally-projecting means having means
for engagement with said locking member to pre
vent unintentional movement of said locking
member.

5. A device of the class described comprising a
relatively fiat rigid plate portion, an integral lat
erally-projecting portion at one end of said plate,
said laterally-projecting portion extending from
one side only of said plate, a locking member re

tatably secured to said plate and disposed longi
tudinally thereof, said locking member having a
portion extending at a right angle to the axis
from one end of said plate on one side only of
thereof and movable from a position in the plane
of said plate to a position angularly disposed to 35
said plate at substantially right angles thereto,
the plane thereof, and said laterally~projecting
said plate having a channel extending for a part
of the distance between the ends thereof and
apertures at the ends of said channel, a locking
member of substantially uniform cross-section
having a portion of its length located in said chan
