PROVISIONAL SPECIFICATION.
An Improved Spring Roller for Window Blinds.
I, HENRY HORDLEY of 88 Stratford Road Birmingham in the County of Warwick
Coach Maker do hereby deolare the nature of this invention to be as
follows:-
This spring roller is partly constructed on the ordinary principle namely an iron or
sheet steel axle running through a barrel or tube made of either tin brass or other
material the steel spring coil being attached to the axle a short distance from one end
and attached to a wooden plug at the other end the said plug fitting in and fixed to the
barrel at one end at the other end is inserted a short tube with two or more slots cut
down it and on the end of this axle two or more catches are fixed so as to lie inside the
small tube.
When the curtain is drawn down it can be fixed at any point where the revolution
of the barrel causes a catch to come opposite a slot in the small tube and fall therein.
And when the catch is released by pulling the blind down a short distance further the
spring causes the blind to run up in the ordinary way.
The object which I have in view in constructing the several parts as above described
is to house the whole mechanism within the length of the barrel and thus by avoiding
any projections upon the ends I am enabled to have the blinds the full width of any
opening to which it is applied.
Dated this 11th day of August 1886.

I, HENRY HORDLEY of 88 Stradford Road Birmingham in the County of Warwick
Coach Maker, 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, reference being had to the accompanying drawings and to
the letters and figures marked thereon:-
This spring curtain barrel or roller for blinds is suitable for railway carriages and
other purposes.
It is partly constructed on the ordinary principle namely an Iron or steel rod or axle
running through a barrel or tube made of either tin brass or other material the steel
spring coil being attached to the axle a short distance from one end and attached to a
wooden plug at the other end the said plug fitting in and fixed to the barrel at one
end, at the other end is inserted a short tube with two or more slots cut down it and
on the end of the axle two or more catches are fixed so as to lie inside the
small tube.
When the curtain is drawn down it can be fixed at any point where the revolution
of the barrel causes a catch to come opposite a slot in the small tube and fall
therein.
0
And when the catch is released by pulling the blind down a short distance further
the spring causes the blind to run up in the ordinary way the velocity of the rotation
of the barrel enabling it to pass the catches.
The object which I have in view in constructing the several parts as above described
is to house the whole mechanism within the length of the barrel and thus by avoiding
any projections upon the ends I am enabled to have the blinds the full width of any
opening to which it is applied.
Referring to the drawings.
Fig. 1. is a section through a curtain barrel or tubular roller shewing the internal
fittings, (a) is the barrel or outer tube or roller, (b) a coil spring attached to the rod or
axle (c) at (d) near one end and to the plug (p) at the other end.
At the opposite end of the axle is the short tube, (t) shewn in plan Fig. 2. with two
slots (s) and made to fit into & close up the open end of the tube (t).
Upon the rod or axle is the disc (e) carrying the catches (f) so placed as to
lie within the short tube (t). This disc (e) with the catches (f) is shewn in plan by
Fig. 3.
The coil spring (b) acts in the ordinary way by causing the barrel to revolve and
draw the blind up around it, when released from being pulled down, and the blind
can be fixed at any point where the rotation of the barrel will cause the slots (s) in the
short tube (t) to come opposite the catches (f.) by allowing the projections (j) on the
catches () to fall into the slots (s). This is done by holding the blind and allowing
it to rise slowly to the point required to be reached.

page_text: When it is required to raise the blind to the top it is only necessary to pull it down
slightly so as to release the catches from the slots (s) and to then release the blind
when the coil spring (b) will cause the barrel (a) to revolve and wind up the blind the
velocity of the revolution of the barrel causing the catches (f) to throw out from the
slots (s) instead of catching therein.
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,
1st. The construction of spring curtains barrels or blind rollers with the mechanism
housed within the barrels as herein described and illustrated so as to enable the blinds
to more entirely cover the openings to which they are applied.
2nd. Constructing spring curtain barrels as herein described and illustrated
with the mechanism inside so as to protect it from the effects of the weather.
