IMPROVE- MENTS IN ROLLER BLIND FURNITURE
Year: 1885

page_text: I JAMES HUDSON of 63 Derby Street, Bolton in the County of Lancaster,
Cabinet Maker, do hereby declare the nature of my Invention for "IMPROVE-
MENTS IN ROLLER BLIND FURNITURE," to be as follows:-
My invention relates to improvements in roller blind furniture and consists in a
novel method of forming and attaching the same, with an improved apparatus for
holding and releasing the cord by which the blinds are raised and lowered.
The rollers to which these improvements are applicable are made circular in
which case the metallic cord pulley is provided with a circular rim or disc, on the
inner side of which is attached a centre pin for the purpose of being driven or
centred into the roller, after which the pulley is secured by suitable screws in a
horizontal position or lengthwise with the roller, thereby making the same firm
and more durable than under the system of screwing them transversely with the
length of the roller. On the circular disc is cast or otherwise a boss sufficiently
long and large in diameter to receive the cord necessary to operate the blind. On
the outer end of this boss is provided a disc with suitable arms or projections,
outside of which the centre is carried and reduced in diameter for the purpose of
forming the centre on which the roller is to revolve at that end.
The roller is mounted in suitable metallic brackets which allow of easy
admittance of the same. In the bracket next to the cord pulley is provided a
horizontal or inclined slot in which vibrates or oscillates a pin secured into a lever
mounted or pivotted to the said bracket. This lever extends below the centre and
is provided with a weighted end in which a hole is formed and through which the
winding cord passes. When the blind is at rest and the cord hangs loosely the
weighted end of the lever causes the lever to hang perpendicular, by which, the pin
in the aforesaid slot is in contact with the arms or projections on the cord pulley,
by which the blind is locked and held until released by pulling the cord, which
operation raises the weighted end of the lever and vibrates or oscillates the pin out
of gear with the arms or projections, when the blind can be raised by pulling the
cord, or drop of its own weight by releasing the cord.

page_text: The opposite end of the roller is provided with a small metallic disc, and is
secured to the end of the roller in a similar manner to the cord pulley, the pivot or
centre being cast to or otherwise.
In roller blinds where the periphery is throughout its length made with a groove
or recess open at one end for inserting a rod with a blind on, the small disc above
referred to is made with a corresponding opening, of either round, square, or other
suitable shape.
The disc of the cord pulley is provided with a hole for inserting the winding
cord immediately opposite the slot receiving the blind in the roller, thereby
dispensing with any tieing or knot on the cord barrel.

JAMES HUDSON of 63 Derby Street, Bolton in the County of Lancaster
Cabinet Maker, do hereby declare the nature of my Invention for "IMPROVE-
MENTS 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 relates to improvements in roller blind furniture and consists in a
novel method of forming and attaching the same, with an improved apparatus for
holding and releasing the cord by which the blinds are raised and lowered. For
this purpose I arrange the mechanical movements and arrangements of mechanism
in the manner I will describe referring to the accompanying drawings.
Fig. 1 is a front view of a blind roller with my improved fittings or appliances
in position for raising, holding, or lowering the blind suspended therefrom; Fig. 2
represents an end view of the cord end of the roller with the lever in position for
locking the blind; Fig. 3 is an end view shewing the lever in position when raising
or lowering the blind, and Fig. 4 represents the bracket for supporting the opposite
end of the blind roller.
The blind roller A is made circular with the slot B in which the blind C is held
by the metallic rod or wire D, or in any other convenient way as desired. The
metallic cord pulley E is provided with the circular rim or disc F and centre pin G,
the latter being for the purpose of being driven or centred into the roller A, after
which the pulley is secured to the end of the roller A by the screws H. To the
side of the circular disc F is cast or otherwise the cord barrel E sufficiently long
and large in diameter to receive the cord J necessary to operate the blind A. On
the outer end of the cord barrel E is fixed the disc L with the arms or projections M,
outside of which the cord barrel E is reduced in diameter to form the centre I on
which the roller A revolves at that end, which is shewn in section in Fig. 5. The
disc F of the cord pulley E is provided with the hole X immediately opposite the
slot B in the blind roller to receive the winding cord J, after which it is secured
thereto by tieing the knot d, thereby dispensing with tieing or knot on the cord
barrel E.
The roller A is mounted in the metallic brackets N and O, the bracket N next
to the cord pulley E is provided with the slot P in which the pin R moves with
the lever S, the latter being pivotted to the bracket N by the pin T. The lower or
outer end of the lever S is provided with the projection b, the latter having the
eyelet-hole c through which the winding cord J passes to and from the barrel E
when raising or lowering the blind. When the blind is at rest the cord J hangs
loosely and the outer or weighted end of the lever S causes it to hang perpen-
dicular as in Fig. 2, by which the pin R in the slot P is placed in contact with the
arms or projections M on the cord pulley, by which the blind C is locked and held;
the weight or pull of the blind acting on the roller A in the direction indicated by
the arrows, thereby pressing the locking pin R against the outer end of the slot P,
in which position it is held until released by pulling the cord laterally as shewn
in Fig. 3, when the lever S swivels and releases the pin R from the arms or

'
projections M, and the blind is raised by pulling the cord J, or lowered of its own
weight by releasing the said cord.
The opposite end of the roller A is fitted with the metallic disc V as shewn in
Fig. 6 or with the disc V and arms V' in Fig. 4, secured by the screws H in a
similar manner to the cord pulley, the centre pin G being cast to or otherwise.
The disc V is provided with the taper or other slot W to enable the rod or wire D
to be inserted with the blind in the slot B in the roller A. To prevent the roller
jumping out of the brackets the bracket O is provided on the outside with the
projections f in which is inserted the pin 7 immediately above the centre I.
In another arrangement I mount the lever S in a horizontal position as shewn
in Fig. 7, in which case the inner or pin end is the heaviest and causes the pin R
to fall to the bottom of the slot P and in contact with the arms or projections M.,
by which the blind is arrested and held in any desired position.
Fig. 8 is a plan of Fig. 7, and Fig. 9 a front view of same shewing the
projection band eyelet-hole c through which the winding cord J passes to and
from the cord pulley E.
The blind is operated by simply pulling the cord J which swivels the pin R
on the lever S as shewn in Fig. 10, and releases the same from the arms or
projections M when it can be raised or lowered at will. When the blind is placed
to the desired position the winding cord J is liberated from the operator's hand
and the pin R drops with the lever S and locks one or other of the arms or
projections M, and the further unwinding of the blind is instantly arrested.
It will be readily understood that my improvements are equally applicable to
the raising, holding, or lowering of maps, plans, and other analogous purposes.
I would have it understood that I do not confine myself to the precise details or
configuration of parts I have shewn and described as the brackets may be inade in
a variety of ways, such as, vertical, horizontal, diagonal, or others to suit the
various arrangements in the construction of window or other frames to which they
may be applied.
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
1. The formation, combination, and use, with a blind roller of the cord pulley E,
disc F, centre pin G, disc L with the projections or arms M, for the purpose
described and set forth.
2. The combination with the bracket N of the slot P, pin T, lever S, projection b
and eyelet-hole c, for the purpose described and set forth.
3. The combination of the bracket O the projections f and pin 1 for the purpose
specified.
4. The respective combinations and arrangements of parts forming my improved
roller blind furniture, constructed and operating substantially in the manner
described and shewn on the drawings.
