1 Claim. (Cl. 20-38)
This invention appertains to doors and other
letter A generally indicates my improved anti-sag
closures, and more speci?cally to an anti-sag de
vice therefor.
Doors have a tendency to sag at their outer
lower corners, which renders the same dif?cult
to open and close. This is particularly true of
doors of a heavy type.
It is, therefore, one of the salient objects of
my invention to provide a device which can be
10 easily and quickly applied to a door of any type,
such as a screen door or a wooden door, and
which will effectively prevent a door from sagging
at its lower outer corner, and which will permit
the taking up of the sag in a door, should the
same be already out of line.
Another salient object of my invention is to
provide an anti-sag device for doors embodying a
?at metal strip adapted to extend diagonally
across a door from its lower corner toward the
inner edge of the door, with means for adjust
ably connecting the strip to a bracket connected
with the door adjacent to said inner edge.
A further important object of my invention is
the provision of novel means for forming the up
25 per end of the metal strip for receiving said ad
justing device, whereby the strip will be effectively
strengthened to prevent breakage or the bending
thereof incident to the operation of the take-up
A still further object of my invention is to
provide an improved attachment of the above
character for doors, which will be durable and
e?icient in use, one that will be simple and easy
to'manufacture, and one which can be placed
35 upon the market at a reasonable cost.
With these and other objects in view the in
vention consists in the novel construction, ar
rangement, and formation of parts, as will be
hereinafter more speci?cally described, claimed,
40 and illustrated in the accompanying drawing, in
which drawing:
Figure 1 is a front elevation of a door showing
my improved appliance connected therewith, the
casing of the take-up mechanism being shown re
45 moved.
Figure 2 is a section through the door taken
on the line 2-2 of Figure 1, looking in the di
rection of the arrows toward the anti-sag device,
the casing for the take-up appliance being shown
50 in section.
Figure 3 is an enlarged detail fragmentary
view showing the casing in position.
Referring to the drawing in detail, wherein
similar reference characters designate corre
55 sponding parts throughout the several views, the
device for a door D.
The door D forms no part of the present inven
tion and can be of any size or character. The
door is connected by means of hinges 5 along one
edge with the door frame 6.
The anti-sag device A comprises an elongated
?at strip 1 formed from metal of the desired
gauge, and this strip is adapted to be secured to
the door by means of suitable fastening elements, 10
such as screws 8. The strap extends diagonally
across the door from the lower outer corner there
of toward the inner edge of the door. The upper
end of the metal strip- or strap 1 is bent laterally
at right angles and then back upon itself to form ll
an ear 9. The bent portion of the metal is con
tinued along the outer face of the strip or strap
for a short distance and can be spot-welded to
the body portion of the strip or secured thereto
by any desired type of fastening element.
The device also includes a bracket Ill, which
is preferably secured by means of fastening ele
ments II to the inner rail of the door. The
bracket I 0 is also formed from sheet metal and is
of a substantially U-shape, having outwardly
extending feet through which the fastening ele
ments ll extend. The U-shaped bracket l0 re
ceives a nut I2 into which is threaded one end of
an adjusting screw I3.
This adjusting screw l3 extends through the 80
ear 9, through the bracket, and into the nut.
The upper wall of the bracket holds the nut
against rotation, and, consequently, by turning
the screw l3 with a suitable instrument, such as
a screw-driver, the strip 1 can be drawn toward 35
the bracket Hi. This will take up any sag in the
door and hold the door in proper position against
further sagging.
In view of the fact that the anti-sagging device
is formed from scrap metal, the same can be 40
secured to ?at wooden doors as well as screen
doors and the like.
If desired and preferred, a removable sheet
metal casing M can be provided for the bracket
and the take-up screw I 3. Ears I 5 are formed
on the casing I 4, which permits the casing to be
secured to the door by screws I6.
From the foregoing description it can be seen
that I have provided an exceptionally simple and
durable appliance, which can be quickly and eas
ily applied to a door by a layman, and which will
prevent the sagging of a door.
Changes in details may be made without de
parting from the spirit or the scope of my inven
tion, but what I claim as new is:
legs, a nut received in said U-shaped bracket
As a new article of manufacture, an anti-sag between the legs thereof, and adjusting screw ro
appliance for doors comprising, an elongated ?at tatably mounted in the aperture of the ear ex
strip of metal having its inner end folded back
upon itself, said folded portion having a laterally
extending apertured ear, the lower end of the
strap being adapted to be secured to the lower
outer corner of a door, a U-shaped bracket
adapted to be secured to the door adjacent to its
inner edge, said bracket having spaced apertured
tending through the apertures of the legs of the
U-shaped bracket and ?tted in said nut, and a
detachable housing for ?tting over the bracket,
ear, and screw.
