IMPROVEMENTS IN ROLLER BLIND FURNITURE
Year: 1884

the Town of Nottingham Commission Agent do hereby declare the nature of my
invention for IMPROVEMENTS IN ROLLER BLIND FURNITURE to be as follows:-
DESCRIPTION OF THE DRAWINGS.
Figure 1. is a front view of the operating parts of my improved roller blind
furniture Figure 2. is a side view of the same, showing the position of each part,
when the blind is stationary. Figure 3. is also a side view showing the position
of the operating parts when the blind is in motion. When the blind is rolled upon
the roller, the cord is fastened to the reel A, then passed through the loop at the
bottom of the latch B. which by pulling the cord, is released from the catchbar C.
the blind then falls of its own weight, winding the cord on the reel, by loosing the
cord the latch B. which swings on an axle or pin on the bracket D. engages with
the catchbar C. and stops the blind at any point. The blind is again raised to any
point by pulling the cord.

I WILLIAM MERRALL SIMONS of Coburg Road in the Town and County of the
Town of Nottingham, Commission Agent do hereby declare the nature of my
Invention for "IMPROVEMENTS IN ROLLER BLIND FURNITURE" and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :--
My invention has reference to that kind of roller blind furniture in which the
blind cord is wound upon a reel or pulley on the blind roller when the blind is
lowered and the blind cord unwound from the reel or pulley when the blind is
raised; and my invention consists of the arrangement or combination of the parts
hereinafter described and illustrated in the accompanying Drawing for fixing
and releasing the blind roller. By my invention the parts for fixing and releasing
the blind roller are very simple in construction and efficient in action.
My improvements are as follows:-On the outer face of one of the flanges con-
stituting the cord reel or pulley on the blind roller, a catch bar is made the said
catch bar crossing the flange in the direction of a diameter. To the bracket
carrying the pulley end of the blind roller a latch or check lever is jointed
the latch or check lever turning in a vertical plane. The top of the short arm
of this latch or check lever is inclined and when in its normal position the said
inclined upper end is situated under and in the path of the catch bar and by
engaging with the said catch bar arrests and prevents the rotation of the blind
roller.
The blind cord passes through an eye at the lower end of the long arm of the
latch or check lever and the weight of the said long arm when it is at liberty to
move, together with the pressure of the check bar f on its upper end, brings the
short upper arm under the check bar. The latch or check lever is taken out of
action to release the blind and maintained out of action by means of the blind
cord. Figure 1 of the accompanying Drawing represents in front elevation and
Figure 2 in end elevation, roller blind furniture containing my improvements, the
parts being represented in their normal or acting position and the blind stationary ;
Figures 3 and 4 represent the same views as Figures 1 and 2 with the blind roller
released for raising or lowering the blind.
The same letters of reference indicate the same parts in all the Figures.
a is the blind roller and b the blind; c is the bracket supporting the pulley end
of the roller shown partly broken off in Figures 2 and 4; d, d² is the pulley or
reel on which the cord e is wound and from which it is unwound; f is the check
bar crossing the back of the flange d of the cord pulley or reel; g, g³ is the latch
or check lever turning on the centre h carried by the bracket c. The top of the
short arm g of the latch or check lever g, g² is inclined and the lower end of the
long arm g carries an eye plate g³ through which the blind cord e passes on its way
to the pulley or reel d, d².
When the blind is stationary the latch or check lever g, g' takes the position
represented in Figures 1 and 2. and its inclined upper end engages with the catch
bar thereby preventing the rotation of the blind roller.

page_text: When it is wished to release the blind roller for raising or lowering the blind,
the blind corde is pulled outwards or from the window. By this motion of the
blind cord the latch or check lever g, gå is turned on its centre h and its short upper
arm g removed from under the catch bar f as illustrated in Figures 3 and 4. The
blind roller a is thereby released and by paying out the cord e and maintaining
the latch or lever g, g² in the position represented in Figures 3 and 4, the blind b
may be lowered and by drawing in the blind cord e the said blind may be raised.
On releasing the blind cord e after the adjustment of the blind the catch or
lever g. g takes the normal position represented in Figures 1 and 2 and by
engaging with the catch bar f arrests the motion of the blind roller and holds
the blind in its adjusted position.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is of
Improvements in roller blind furniture of the kind described
The arrangement or combination of the catch bar f on the outerside of the cord
reel or pulley on the blind roller with the jointed latch or check lever g, g², 9³ for
fixing and releasing the blind roller substantially as hereinbefore described and
illustrated in the accompanying Drawing.
