IMPROVED MEANS OF AND APPLIANCES FOR SUPPORTING AND ACTUATING VENETIAN AND LIKE BLINDS
Year: 1884

page_text: I HENRY CORNELIUS COLLYER of 36 Farringdon Street in the City of London
Window Blind Manufacturer do hereby declare the nature of any said Invention
for IMPROVED MEANS OF AND APPLIANCES FOR SUPPORTING AND ACTUATING
VENETIAN AND LIKE BLINDS to be as follows:
The object of this Invention is, to so support the slats or laths of venetian and
like blinds that the usual tapes or ladders can be dispensed with and in lieu thereof
chains are arranged in such a manner that each slat or lath which is provided with
a clip fastener can by a ring be attached at pleasure to the chain and be removed
at will.
Four or more chains can be used to each blind so that the slats or laths can be
operated in a similar manner as those with tapes or two chains can be arranged on.
one side only, the other side having cords by which the angle of the slats can be
set or by which they can be raised and lowered.
When four or more chains are used I employ the usual lifting cords so that all
the laths may rise against one another in succession or I so divide or stage off the
series of laths into divisions of the lifting cords as to compel them to lift in stages
in succession.
For the purpose of my Invention I make holes in the laths at the desired
distances apart and I lace a short length of wire into each hole each wire being
bent to form a loop beyond the edge of the lath. The two ends of the wire are
forced down upon the lath and are partially embedded in the same, snug alongside
the wire next the loop.
Small rings are hung on the loops and are also attached to the chains from which
the laths become suspended.
The chains can be on both side edges of the slats or on one side edge only
in which case I attach cords to the opposite side edges, the raising or lowering of
which cords sets the slats at the desired angle.
By this Invention venetian blinds can be made to last much longer without
needing repairs, the chains and connecting loops and rings not being so readily
destroyed by the action of the sun and by exposure as the usual tapes are.
Dated this 8th day of January 1884.

Agent for the Petitioner.

page_text: I HENRY CORNELIUS COLLYER of 36 Farringdon Street in the City of London
Window Blind Manufacturer, do hereby declare the nature of iny said Invention
for " IMPROVED MEANS OF AND APPLIANCES FOR SUPPORTING AND ACTUATING
VENETIAN AND LIKE BLINDS" and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
The object of this Invention is to so support the slats or laths of venetian and
like blinds that the usual tapes or ladders can be dispensed with and in lieu thereof
chains are arranged in such a manner that each slat or lath which is provided with
a clip fastener can by a ring be attached at pleasure to the chain and be removed
at will.
Four or more chains can be used to each blind so that the slats or laths can be
operated in a similar manner as those with tapes or two chains can be arranged on
one side only, the other side having cords by which the angle of the slats can be
set or by which they can be raised and lowered.
When four or more chains are used I employ the usual lifting cords so that all
the laths may rise against one another in succession or I so divide or stage off the
series of laths into divisions of the lifting cords as to compel them to lift in stages
in succession.
The annexed sheet of Drawings show my Invention in detail as I prefer to carry
it into practice.
Figure 1 is an elevation and Figure 2 an edge view of a venetian blind with the
slats or laths A A attached near their ends by loops B, B, and rings C C to
chains D, D, as more particularly represented at the part sectional view Figure 3
the pull up and lowering cords E E being fitted in the usual manner.
The top of the chains D, D, are rove over pulley wheels F, F, as seen at Figure 2
and any down pull ou either of the chains will alter and set the angle of the laths
as desired.
If the slats be lifted by the cords E E each length of chain between the slats
becomes looped as shown by the lower parts of Figures 1 and 2 and when the slats
are lowered and set flat with each other or "closed" they may readily serve as
shutters by fastening the chains at the lower part to a portion of the wainscoting
of a room or other place at which such blinds may be fitted.
The loops B B are of wire, flat or round, and they may have their ends turned
and forced into the wood of the lath as at Figures 3 and 4 or be otherwise secured
to fix them in position such as by rivet pins being passed through.
The wire of the loops if it be flat as at Figure 5 may be wrapped around the
lath A and be pressed into the wood to be held in place by stud pins the projecting
ends forming the loops as shown.
The chains may be at the back as at Figure 6 or at the front portion of the blind
in which case I use the ring CC or additional rings G G as guides for the pull up
cords E, E, as at Figures 4, 6 and 7 the chains D, D, being attached at their upper
ends to rollers H, H, to run on bars I, I, fitted for the purpose of allowing the laths
when lifted to lodge themselves side by side as at Figure 7 the chains between
every two laths looping themselves within them.
The bars I, I, are at an incline and when the cords are run out to lower the slats
the rollers H H gradually travel down the inclines so that by the time the blind is
completely lowered and the slats assume a nearly vertical position for their edges
to overlap each other as at Figure 8 they all lie close to the window.
The front edges of the slats A. A at Figures 4 and 6 have suspension cords J. J.
with a knot K, K, for each slat to rest on which cords are arranged to alter the

page_text: angle at which the slats of wood or its equivalent material may be set, the chain
loops acting as fulcrums on which the slats can move or such cords J J may be
dispensed with and the front end of the slats be free as at Figures 7 and 8.
Venetian blinds thus supported are suitable for outside as well as for insides of
windows and in many instances they can be fitted as venetian shutters to shop
fronts in substitution for roller blinds the laths when raised being boxed in behind
the facia board particularly with the arrangement shown at Figure 7 which only
requires guide irons at the ends of the laths to follow the movements of the
rollers H H to keep the slats closed to when lowered.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is,
i
The improved means and appliances for supporting and actuating venetian and
like blinds as set forth and substantially as shown in the annexed Drawings.
Secondly. I claim the combination of chains D, loops B rings C, G, and slats or
laths A in the manner described and substantially as shown in the annexed
Drawings.
Thirdly. Suspending slats or laths of venetian and like blinds by chains D
coupled thereto by rings C and loops B on said slats as set forth and as shown in
the annexed Drawings.
Fourthly. The method of actuating venetian and like blinds by cords E as shown
at Figures 4, 6 and 8 so that the slats A may take a position side by side when
raised as at Figure 7 as set forth.
