Improvements relating to Spring Roller Blinds.
I, SEPTIMUS ROSTRON, of 74 St. Lukes Road, Southport, Lancashire, Painter
and Decorator do hereby declare the nature of this invention to be as follows :-
--
My invention consists of a device to allow of raising and lowering spring roller
blinds. Said device comprises a bracket-catch and star wheel adapted to one end
of the blind roller and actuated by a single cord. It is intended to serve as a useful
adjunct to existing appliances employed for raising, lowering or holding the class of
window blinds, suspended from the well known "spring rollers," and with a view to
readily, and with great facility ensure the motion of the blind being arrested when
desired and vice versa to allow of the unwinding of the blind to any desired extent.

COMPLETE SPECIFICATION.
Improvements relating to Spring Roller Blinds.
I, SEPTIMUS ROSTRON, of 74 St. Lukes Road, Southport, Lancashire, Painter
and Decorator 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 :-
My invention consists of a device to allow of raising and lowering spring roller
blinds.
In the accompanying drawings
Figure 1 is a front elevation of my improved roller blind;
Figure 2 is an end elevation shewing the bracket catch and star or ratchet
wheel;
Figure 3 is a plan of same; and
Figure 4 an end elevation shewing an ordinary bracket in which the roller blind
spindle revolves.
Like letters of reference indicate corresponding parts in the several views.
In accordance with my invention I employ a bracket catch A, and star or ratchet
wheel B, adapted to one end of the blind roller D, and actuated by a single cord C,
one end of which is fastened to the blind roller D and winds upou a suitable pulley
or drum provided for same as shown in Figures 1 and 3.
Said bracket catch A has a hole punched or cut therein at its lower end through
which passes the actuating cord C.
My improved device is intended to serve as an useful adjunct to existing
appliances employed for raising, lowering or holding this class of window blinds and
with a view to readily, and with greater facility ensure the motion of the blind
being arrested when desired, and vice versa, to allow of the winding or unwinding of
the blind to any desired extent.
A window blind fitted with my improved device, is actuated as follows; viz. :
when a blind is rolled upon the blind roller D, and then upon the cord C being
pulled, the bracket catch A is released from the star or ratchet wheel B, and the
blind is allowed to unwind to any length by its own weight, and whilst doing so it
winds the cord C upon the pulley or drum as shown Figures 1 and 3. When
[Price 8d.1

page_text: raising the blind the cord is pulled down and so winds the blind upon the blind
roller.
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.
The means for raising and lowering window blinds substantially as herein set
forth and shown in the accompanying drawings.
Dated this 15th day of July 1892.
