32 Claims. (Cl. 156-17)
This invention relates to improvements in the
method of manufacturing from a thin strip of
sheet metal a Venetian blind slat by piercing a
plurality of apertures proximate the edge portion
5 of the strip and forming said edge portion into
a stiffening or reinforcing member extending
longitudinally of the strip so that the apertures
in the ?nished slat are disposed in a plane sub
blind slat from a thin sheet metal strip so that

of the slat shown in Figure 4 with a modified
form of tape fastening clip positioned proximate 15

Another object of the invention is to construct
a. Venetian blind slat forming means in combi-,

tape to the slat.

Another important object of the invention is to
,provide means for using slats made of thin sheet
material, preferably sheet metal, in combination
with what may be described as single supporting
tapes as distinguished from the double, or the
so-called ladder tape heretofore used extensively
in the manufacture of such blinds.
Another object of the invention is to provide
means for securely fastening the tapes to the
edges of the slats by a clip. or other fastening
means, which- means may be easily removed as
occasion requires.

Another object of the invention is to reduce the
overall bundling height of the slats and head

to the top of the window.

erally described as a head bar mounted in any
suitable manner at the top of a window, such
for example, as by means of suitable supporting
brackets. A series of slats, terminating in a low
ermost ‘slat is suspended from the head bar by
any suitable form of ?exible members, such as
tapes, which are usually secured to the uppermost slat from which all of the other slats are
supported. All of the slats and the head bar
are perforated to permit the passage therethrough 45
of raising and lowering cords‘ which are secured
to the lowermost slat and conducted by guiding
pulleys to an accessible position at one side of
the blind. Inasmuch as my present invention
relates principally to the formation of a slat
and the method of making the same, so that the
supporting members or tapes may be securely
attached to the edge face thereof by means of
clips it is believed unnecessary to illustrate the 55

complete blind, particularly in view of the 101
lowing description.
Referring now to Figure 1, it will be seen that a
series of slats II are supported in spaced rela
tionship with one another, by ?exible members I!
made of any suitable ?exible material, but pref
erably fabric tapes as here shown. All of the
slats are perforated as at I‘! to permit the pas
sage therethrough of a raising and lowering cord

made of thin sheet metal strips, stiffened by hav
ing the edges thereof bent over with respect to
the plane of the strip. The formation of this
stiil'ening edge also gives to the slat that appear
15 ance of stability, from the standpoint of over-all
slat thickness, to which one may have become ac
customed by viewing the more common type of
Venetian blinds having wooden slats.
The right-hand end of Figure 2 illustrates a
strip of thin sheet metal after the first operation
diameter of the wire from which the clip is made
will usually be greater than the thickness of the
material of the strip.
Figures 8 and i0 illustrate how, after the clip
above described is inserted into one of the tape
loops 26, it may be pressed into the holes I. and
20, which holes have a diameter less than the
distance between the ends I! and I! of the hooks
and the arms 3| and 32 by merely applying suf
?cient pressure on the clip to ?ex the ends of 10
the hooks towards the arms of the clip until the
clip is pressed into the slat far enough for the
ends of the hooks to prevent the withdrawal of
the clip through the holes I! and 2|. It will
also be understood that the amount of deforma
tion required of the hooks is not sufilcient to
cause the material of the clip to acquire a per
manent set, but that whenv the clip ?nally con
nects the tapes securely to the slat it will assume
its original shape.

simultaneously piercing four groups of holes I9,

scribed.
For purposes of de?nition, the surface of the
strip may be divided by lines 22 passing lon
gitudinally through the centers of the holes I!
30 and 20 at the sides of the strip, respectively, and
which removal is eifected by inserting the point
of any suitable instrument through the hole 2|

the lines 22 I shall refer to as a web, and the
It will, however, be understood that the clip
could be just as effectively employed if a single
slot 31, see Figure 8a, were formed in the edge
face of the slat equal in width to the diameter of
the holes Is and 20, and having a length suitable
for the insertion of the clip just described, be

areas between the edges of the strip and the
lines 22 I shall refer to as ribs, while the areas
between the lines 22 and 22 will be referred to as
the edge portions of the strip.

The next operation in the forming of my slat
is that of stamping or otherwise forming ribs 24
and 25 respectively at each longitudinal edge of

serves no purpose except to contribute to the stiff
ness and rigidity of the slat as a whole. In view
of the above, it will be understood how a single

lines 28 into a position at right angles to the edge slot perforation may be employed for the
plane of the strip. Thereafter the edges of the engagement of the clip with the slat instead of

pose of analysis and that one or more of said ' of the ribs would be somewhat greater than those
steps may in practice be performed simultane
ously.
The tapes I6 above described comprise a plu
rality of spaced tubular loops 28 disposed on one
side thereof in any suitable manner, as being
stitched to the tape, or woven integrally there
with. It will be understood that the distance be
tween the loops 28 is equal to the desired distance
between the slats, see Figure 1.
.
Figure 6 illustrates what I shall describe, for
the want of a better name, as a spring clip 30,
or a fastening. means, by which the tapes l8 are
secured to the edge face of the slats. 'Ihe clip
20 is preferably made of a piece of spring wire
having the ends thereof bent to form arms 3| and
22, and having hooks 32 and 34 formed by bend
ing a portion of the arms outwardly and rear
wardiy until the ends 35 and 36 of the hooks
70 are normally spaced from the arms and disposed
in a line removed from the line of the head of
the clip, indicated by the location of the numeral
II. It will be understood that when the clip is
bent as described, that the parts 20 to 24 are all
disposed in the same plane. In practice, the
illustrated in Figures 2 and 3 in order to provide
for the formation therein of holes similar to II
and 20. Obviously'when a slat of this generally
shaped construction is formed, the release holes
2| become unnecessary. In either case I have
found that a desirable slat for use with my clips
may be made of comparatively thin sheet metal
having an edge face formed thereon of an effec
tive width of about three thirty-seconds of an
inch.
-
Figures 4, 5,7, 9 and 11 show a modified form
of the slat and clip constructions just described
in connection with Figures 6, 8 and 10. In the de
scription of these modifications, I shall employ
similar reference numerals to represent portions
thereof which are similar to the structures above
described. The principal difference in the con
struction of this modi?ed slat is that rectangular
perforations 40, see Figure 4, are punched in the
sheet metal instead of the holes ll'and 2| above
described, and the ribs 24 and 2| are notched at
4 I. It will be seen that when the ribs of the strip
are formed as above described, the perforations ll
and notches ll form a passage through the tubu- I

Figure 7 illustrates a form of spring wire clip
construction to be used with a slat like that shown
in Figures 4 and 5 and comprises a head portion
44 having a hook 45 formed at one end thereof by
bending the wire through reverse curves so that
10 the hook 55 extends longitudinally beyond the
head ti and is disposed at one side of the head
in a line parallel thereto. The wire at the other
end of the clip is bent to form an extension 56
terminating in a hook 4?, both of which lie in
15 the same plane as the book did.

described as the upper and lower major surfaces

35 above described, these holes are disposed in the
edge face of the slat and lie wholly between the

vsurfaces in the embodiment of the invention here
shown may be said to include the planes passing
40 through the uppermost and lowermost surfaces
of the tubular reinforcements formed, as above

portant reason for forming the slat in this manner
is to be able, with the clip means above described,
45 to fasten the tapes to the slats so that when the
