Improvements in or relating to Venetian Blinds.
I, WILLIAM PALMER of Wood Street, Kettering, in the County of
Northampton, Cabinet Maker, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the means for raising and lowering
Venetian blinds of the kind in which slats of wood or other material are suspended.
at equal distances on tapes or the like, and raised_and_lowered by cords threaded
through slots in the slats and passing over pulleys in the upper cross rail or beam.
As arranged heretofore in order to raise or partially raise the blind the cord
must commence to gather the slats together from the bottom, and if, as is mostly
the case, the blind is only partially raised a collection of slats will extend across
the window at the foot of the blind and thus shut out light, this body of slats can
only be removed from such light-intercepting position by completely raising the
blind.
In carrying out my invention in addition to the ordinary cords which extend to
the foot of the blind, I employ auxiliary cords which are threaded through the
slots in the slats but instead of being carried to the foot of the blind the ends are
secured to the suspensory tapes by an adjustable or detachable fastener at any point
in the length of the blind.
The detachable fasteners may each be formed by two buckles or loops provided
with a central pin which is detachable; these two buckles or loops may be
connected to each other by a flat link the ends of which are pivotted to the central
pin of the two buckles or loops so as not to interfere with the opening and closing
of the blind. The link, which is of the same length as the width of the slats may
be provided with a slot for the passage of the ordinary cord and a hole, stud, or
hook to which the end of the auxiliary cord is connected.
The two buckles or loops of the detachable fasteners are connected (by removing.
and replacing the central pin) to the back and front suspensory tapes and the
connecting links are passed between the slats at this point and the ends of the
auxiliary cords secured thereto, the point at which they are attached to the tapes
is governed by the height to which the blind is usually drawn when partially
raised.
When it is desired to partially raise the blind the auxiliary cord is pulled and
it will commence to gather the slats at the point where the fasteners are fixed,
and if desired it will gather all above it up to the top rail out of sight. That
part of the blind below the fastener will remain in its extended condition and may
be opened to admit light or closed, or further raised by the ordinary cord as
desired, the appearance of the blind when partially raised is also very much
improved.
The auxiliary cord may be carried over the pulleys of the ordinary cord or over
additional pulleys, both sets of cords, which are preferably of different colours to
distinguish them, may be also carried through and held by the same or independent
cord grips cleats or fastening arrangements.

Improvements in or relating to Venetian Blinds.
I, WILLIAM PALMER of Wood Street, Kettering, in the County of
Northampton, Cabinet Maker, 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 :--
This invention relates to improvements in the means for raising and lowering
Venetian blinds, of the kind in which slats of wood or other material are suspended
at equal distances on tapes or the like, and raised and lowered by cords threaded
through slots in the slats and passing over pulleys in the upper rail or beam.
It will be best understood by reference to the accompanying drawings, in
which,
Figure 1 is a front view showing the upper and lower part of a blind to which
my invention is applied.
Figure 2 is a plan.
Figure 3 is an elevation partly in section, and
Figure 4 a plan of a detachable tape grip or connecting arrangement.
Figure 5 is an elevation partly in section, and
Figure 6 a plan showing a modified form of tape grip or connecting
arrangement.
Like letters indicate like parts throughout the drawings.
Figures 3, 4, 5 and 6 are drawn full size.
In order to raise or partially raise the blind the cord as arranged hitherto must
commence to gather the slats together from the bottom, and if, as is mostly the
case, the blind is only partially raised a collection of slats will extend across the
window at the foot of the blind, and thus shut out light, this body of slats can
only be removed from such light intercepting position by completely raising the
blind.
In carrying out my invention in addition to the ordinary cords A extending to
the bottom of the blind I employ auxiliary cords B which may be threaded
through the ordinary slots in the slats, but instead of being carried to the foot
of the blind, their ends are connected at any intermediate point in the length
of the blind preferably to the suspensory tapes C by detachable grips or
connections D.
The detachable grips (see Figures 3 and 4) may each be formed by two buckles
or loops E each provided with a detachable pin E which is shaped so that it will
not pass through the buckle E. A loop of the suspensory tape C is passed through
the buckle E and the pin E' is then placed in the loop of the tape C forming a
frictional grip as shown.
The two buckles E of each grip are connected by a link F in the ends of which
the buckles are pivotted so as not to interfere with the opening and closing of the
blind.
The links F which are preferably of the same length as the width of the slats
may be provided with an opening F for the passage of the cords A and a hole or
holes F to receive the ends of the auxiliary cords B.
The two buckles E of each grip are connected to the back and front suspensory
tapes C in the manner described, and the ends of the auxiliary cords are secured to
the links F, the point at which they are attached to the tapes is governed by the
height to which the blind is usually drawn when partially raised.
When it is desired to partially raise the blind the auxiliary cords B are pulled
and they will commence to gather the slats at the point where the grips are fixed
and if desired it will gather all above it up to the top rail out of sight. That
part of the blind below the grips will remain in its extended position and may be

page_text: opened to admit light, or closed, or further raised by the ordinary cord A as
desired.
The auxiliary cords may be carried over the pulleys of the ordinary cord A or
over additional pulleys B' as shown, both sets of cords which are preferably of
different colours to distinguish them may be carried through and held by the same
or independent cord, grips, cleats or fastening arrangements.
In a modified form of tape grip shown in Figures 5 and 6 the pins E' are secured
to the links F and in this case are passed through the buckles E and prevented
from accidentally returning by forming the pins E₁ of a greater length than the
length of the openings in the buckles as shown. A loop of the suspensory tape C
is passed through the opening in the buckle E and the pin E is then inserted from
the same side one end of the pin E being first inserted and the pin moved
longitudinally in the buckle until the other end can be passed through.
Having now particularly 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. In a Venetian blind the employment of a cord or cords B connected to the
blind at any intermediate point in its length substantially as described and
illustrated in the accompanying drawings.
2. In a Venetian blind the combination with a cord A of an auxiliary cord such
as B connected to the blind at any intermediate point in its length substantially as
described and illustrated in the accompanying drawing.
3. In a Venetian blind the combination with an auxiliary cord such as B of a
detachable tape grip formed by a link F buckles E pivotted to the said link and
pins E substantially as described and illustrated in Figures 3 and 4 of the
accompanying drawings.
4. In a Venetian blind the combination with a cord such as B of a detachable
tape grip formed by a link F provided with pins E' and buckles E substantially as
described and illustrated in Figures 5 and 6 of the accompanying drawings.
