I JOHN PARTRIDGE of 29 City Road London in the County of Middlesex
Window-Blind Fitting Maker do hereby declare the nature of my Invention for
IMPROVEMENTS IN WINDOW-BLIND FITTINGS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention consists of a spring or springs and a movable arm with an
alterable adjustment made of metal or other suitable material for the purpose of.
holding or retaining Flange wheel Roller Blinds or similar articles in position.
It is attached to a Flange Wheel or Wheels or other form used or made for the
same purpose on or in roller or other means to which a Flange wheel may be
employed to gather material. The purpose of this invention is effected by the
application of a self acting spring A or springs over, around or against the coils
of line E or other drawing or revolving means employed to revolve a Flange
wheel D for the before named purposes.
The power of holding or retaining is assisted or added to by the movable arm B
and alterable adjustment C in the following way, The movable arm B fitting
round or against the wheel B., pin F. or roller and the alterable adjustment being
positioned to obtain a hold or lodginent against a desired point of contact a power
is exerted which is transmited to the movable arm B which fits wheel, pin F or
roller and obtains a bearing against same when the Blind is pulled down or.
at rest.
The power of self acting spring is increased or decreased automatically, by
increasing or deminishing of the number of coils of line brought on or drawn off
spindle of Flange Wheel, the force of contracting power of spring is increased by
the accumulating coils of line when the Blind is drawn down and the Blind bangs
it weight on roller and the spring being relieved as the Blind is drawn on to
roller.
The line is guided on wheel by a hole G made in self acting spring and is closely
pressed round spindle by the spring bearing on line thereby the coils of line are
prevented from becoming entangled when the Blind is drawn down.
The before described invention has the following advantages.
It can be easily and readily applied to its purpose independent of any fittings
on bearers, or brackets on which the pins of wheel or roller revolve.
It is easily applied, (It is self acting) to existing Blinds or fixings.
It is durable, simple and compact in form.
Features of Novelty as follows.
The application of a spring or springs to the coils of line accumulating or
TAL

page_text: employment of the varying size of diameter of same collected lines to obtain an
increasing and deminishing power of restraint or control of same in position.
The employment of an arm with an alterable attachment to a self acting spring
or other means of control or restraint applied to a Flange Wheel Roller Blind or
similar article the same being attached to a Flange wheel independent of fitting on
bearers or brackets on which pins of wheel or roller revolve, or on the window-
frame to hold such independently attached fitting in working position when the
Blind is pulled down.
The employment of an alterable adjustment to find a hold or lodgment and by
the resistance thus obtained by association with the movable arm to effect a
second or double means of restraint upon. a Flange wheel Roller Blind or similar
article.
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 John Partridge of 29 City Road London) Claim The application of a spring
or springs to the coils of line increasing or decreasing upon the spindle of a Flange
wheel Roller Blind or similar articles, to effect a varying means of restraint or
control of the working and holding same in position.
The employment of a movable arm with an alterable adjustment to control and
hold in a desired position a fitting for the control of the working a Flange wheel
Roller Blind or similar article, by a fitting entirely and independently attached to
a Flange wheel and revolving pin.
The employment of same or similar movable arm and alterable adjustment to
obtain a second or double means of control (or an only means of control) by a
fitting attached entirely to Flange wheel or pin on which it revolves.
I claim to vary form of self acting spring by folding, rolling or twisting same
also to make the said spring in one or more parts or by several connected springs
to obtain the same object namely, the control of the working of a Flange wheel
Roller Blind or similar article.
