1 WILLIAM CLUSE of Boyne House Whetstone, Middlesex, Engineer, do hereby
declare the nature of my said invention to be as follows:-
The object of this invention is to construct blind and like roller fittings in such a
manner that a blind by means of an endless cord or other can be drawn up or
down in any position and be retained.
For the purpose of my invention I provide the roller end with a projection or axle
of oval rectangular or equivalent shape and I provide the furniture which is affixed to the
window style with a pair of jaws hinged and capable of closing by spring or otherwise
upon the narrow part of the axle to hold the roller in position but capable of being
forced apart or opened for the broad part of the oval or other shaped axle to turn in
when the blind has to be raised or lowered; the nip of the jaws against the narrow
part of the axle fixing the blind in the required position.
In some cases one movable jaw only may be used.

page_text: I WILLIAM CLUSE of Boyne House, Whetstone, Middlesex, Engineer, do hereby
declare the nature of my said invention 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 construct blind and like roller fittings in such a
manner that a blind by means of an endless cord or other can be drawn up or down and
be retained in any position.
For the purpose of my invention I provide the roller end with a projection or axle
of oval, rectangular, or equivalent shape and I provide the furniture which is affixed
to the window style with a pair of jaws hinged and capable of closing by spring or
otherwise upon the narrow part of the axle to hold the roller in position but capable of
being forced apart or opened for the broad part of the oval or other shaped axle to
turn in when the blind has to be raised or lowered the nip of the jaws against the
narrow part of the axle fixing the blind in the required position.
In some cases one movable jaw only may be used.
The invention will be understood by the annexed drawings.
Figure 1 is an end view of a blind roller showing the cord A. and pulley B supported
by the axle C in the bracket D in the usual manner.
E is an oval, or it may be other shaped; cam on the axle Cembraced or pressed
against by two bars F, F, suspended from a strip G of the bracket D and drawn
together by a spring H so as to keep the two bars F, F, in contact with the cam E
when the roller is rotated by the cord A so that when the narrow part of the cam is
in the position shown, the two bars F, F, by the action of the spring H will retain
the blind roller in any desired position.
According to Figure 2 of the drawings 1 show the position of the cam E reversed
and pressed upon by two horizontal springs H, H, affixed to the bracket D, but at
Figure 3 show the suspended bars F, F, outside the bracket. D and as having the
spring below the cam E for the purpose before described.
I have in the drawings only shown an oval cam but any shape of cam on the axle C
or on the roller B can be adapted, the main feature of the invention being fitting
appliances in connection with the bracket or furniture of a roller blind that a pressure
of a spring or springs can be utilized substantially in the manner described for retaining
the blind at any desired position to which it may be drawn.

page_text: 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
The construction of roller blind fittings that a spring or springs may act directly
or indirectly upon some part of a blind roller or appliance fitted thereto for retaining the
blind at any position when operated by an endless cord A and whereby the usual cord
fasteners are dispensed with."
