1 Claim. (Cl. 292-—302)
This invention relates to a fastening device for
securing a removable member, such as a storm
window, screen, shutter or the like, to- a ?xed
member, such as a window casing, frame or the
' 5 like, and its principal object is to provide an im
proved device which is of simple design and of
strong and durable construction, which is effi
cient and reliable, and which may be manufac
tured and sold at a relatively low cost.
The members | 5 and I6 are secured to the
frame of the storm window and casing, respec
tively, at corresponding locations, as shown in
Figs. 1 and 2, so that when the storm window is
applied to the window casing these members are
effective to hold the frame of the storm window
snugly against the casing with the lower part of
the latter contiguous to the sill. The socket and
tion and the accompanying drawing, wherein:
head elements 2| and 26 are so positioned that
the weight of the storm window is effective to
cause these elements to draw it inwardly, thus
ensuring a snug ?t and eliminating looseness be 15
window casing and a storm window secured there
'15 to by means of a fastening device constructed in
accordance with the present invention;
Fig. 2 is a vertical section through the assem
blage shown in Fig. 1;
Fig. 3 is a front elevation of a portion of a win
20 dow casing and a screen secured thereto by means
of a fastening device constructed in accordance
with the present invention;
Fig. 4 is an end elevation of the assemblage
shown inv Fig. 3; and
Figs. 5 and 6 are perspective views of the dif
ferent parts of the fastening device.
Referring to Figs. 1 and 2, the embodiment
shown therein comprises a window casing |0 pro
vided with the usual sill II, and a storm window
30 l2 which ?ts snugly against the casing I0, as
shown more clearly in Fig. 2. The storm window
is detachably secured to the window casing by
means of a fastening device consisting of inter
locking parts 15 and 16, shown in Figs. 5 and 6.
The member l5 comprises a plate~like element
20 integral with a socket member 2| which is
generally wedge-shape in longitudinal section.
The plate-like element is formed with a pair of
spaced openings 23 to accommodate screws or
40 like fastening elements by means of which the
member I5 may be secured to the frame of the
storm window l2, and the rear edges of the socket
2| are provided with transversely aligned slots or
Further objects and advantages will be appar
ent from a consideration of the following descrip
Fig. 1 is a rear elevation of a portion of a
ings 24 formed in the rear edge of the socket
member when the parts are in interlocking posi-.
openings 24 spaced from its lower end.
The member I6 comprises a plate-like element
25 integral with an offset, generally wedge-shaped
head 26 of substantially the same size and shape 1
as the interior of the socket member 2|. The
plate-like element 25 is also formed with a pair
50 of spaced openings 21 to accommodate screws or
like fastening elements by means of which the
member I6 may be secured to the inner face of the
casing 10, and the rear of the head is provided
with a transversely extending slot or opening 28
55 adapted to register with the corresponding openg
tween the parts, which might otherwise develop.
If desired, the lower edge of the storm window
may be provided with a weather strip 30 (Fig. 2).
In orderto lock the fastening members I5 and I6,
a small pin 32 (Fig. 2) may be inserted in the
openings 24, 28, this pin, when thus positioned,
being effective to prevent relative movement of
these parts.
The embodiment shown in Figs. 3 and 4 illus
trates the use of my improved fastening device
to secure a screen to the window casing. In this
embodiment the members l5 are secured to the
vertical edges of the screen 35 and the members
l6 are secured to corresponding locations on the
outer face of the window casing |D.
' 30
In each of the embodiments herein shown four
sets of fastening devices are used, although it is
to be understood that if desired a greater or
lesser number may be employed. In any case the
storm window or screen may be readily attached 35
to the window casing merely by applying it so
that the socket members I5 carried thereby ?t
over the heads 26, after which the locking pins
32 may be inserted into the openings 24, 28 to
lock the parts in position. In order to remove
the storm window or screen, it is merely necessary
?rst to remove the locking pins and then lift the
window or screen upward to disengage the mem
bers I5 and I6.
While I have shown and described one desirable
embodiment of the invention, it is to be under
stood that this disclosure is for the purpose of
illustration and that various changes in shape,
proportion and arrangement of parts, as well as
the substitution of equivalent elements for those 50
herein shown and described, may be made with
out departing from the spirit and scope of the
invention as set forth in the appended claim.
I claim:
A fastening device for securing separable mem 55
bers in ?xed position, comprising a plate mem
ber formed with an integral oifset substantially
Wedge-shaped head, said plate member being
adapted to be secured to one of said members so
as to hold said head in spaced relation thereto,
said head having an opening in one face, a socket
member adapted to be secured to the other of said
members, said socket member having an opening
in one edge thereof, the interior of said socket
member being shaped to receive said head so that
when in assembled relation the opening in said
head registers with the opening in said socket
member, and a locking member comprising a pin
adapted to be inserted into the openings in said
socket member and head so as to hold the parts in
?xed position.
