PROVISIONAL SPECIFICATION.
Window Blind Mounting.
I GEORGE BENSON 48 & 50 Fountain Street Belfast Manufacturer do hereby
declare the nature of this invention to be as follows:-
the section.
An improved mounting for window and other blinds. For a roller I use one of
wood either circular or many sided. In this roller I cut a slot and into this slot
insert a slip fitting loosely. Or I simply flatten one side and use a slip to complete
Either in the slip or roller I insert fine pins and between the slip and
roller I place the end of the blind. I then screw the slip to the roller with as
many screws as the length requires. This attaches the blind firmly to the roller.
At one end of the roller I place a simple flanged socket of the usual kind with a
pin in centre. At the other end I place a socket with two flanges and a barrel for
winding the cord on. The outer flange has a waved or corrugated edge, and for
heavy blinds both flanges are corrugated. The pin in the end of the plain socket
is carried in the arm of a bracket having a slot. The bracket that carries the
other end has an arm with a suitable hole drilled to carry the other end of the
roller. Above the roller are two small arms with slots. In these slots and behind
the corrugated flange or flanges, swings a lever. The top of this lever is bent
forward and is perfororated to admit the blind cord. The bottom is shaped to fit
one of the waves or corrugations in the flange or flanges. I employ a spring to
push the end of the lever against the flange or flanges. When stationary the
contact of the lever with the flange or flanges keeps the blind in its place. But
when the cord is pulled the lever is released and the blind can be rolled up.

GEORGE BENSON 48 & 50 Fountain Street Belfast Ireland 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:-
To the left side of a blind roller I attach an ordinary disc flanged or otherwise
with centre pin. I fasten this disc to the roller by screws. The pin of the disc
is carried by a slot in a carrying bracket; so that the roller can be easily lifted in
or out.
For a roller I prefer using a round or hexagonal, slip of wood divided
longitudinally into two parts, the one section being at least twice as large as the
other. The blind being placed between the two sections. I screw the small
section tightly on to the larger one, thereby firmly attaching the blind without
using tacks &c. At the right hand of the roller I employ a barrel for winding the
cord on, carried between two discs.
The inner disc is the same as that on the left side of the roller. But the outer
disc has corrugated or waved depressions on its edge. The barrel revolves by

means of a centre pin in a hole in the arm of a carrying bracket. This bracket
has above its carrying arm two smaller arms slotted at their extremity. Between
and on these two arms swings a two armed lever. The lower arm of this lever
carries a pawl shaped to fit into the corrugations of the outer disc and has on its
back a V shaped spring. One arm of this spring lies on the lever, the other
presses against the roof of the bracket and forces the end of the lever into the
corrugations of the disc. The upper arm of the lever projects over the blind cord
and carries a roller over which the blind cord passes.
In the drawing A is the barrel with the discs, A 1 is the inner-disc, A 2 is the
outer disc with corrugations, A 3 is the pin, A 4 the barrel made in two sections

right hand carrying bracket, B1 is the arm for the pin, B 2 and B 3 the smaller
arms slotted to carry the lever, B 4 the roof of bracket. C is the lever, C 1 is the
roller over which the blind cord passes, C 2 is a projection at a side bearing of the
roller prolonged downwards and used for carrying a supplementary cord if
required. 3 is the lower end of the lever with pawl to fit into the depressions of
the corrugated disc. C 4 is the V shaped spring, C5 the pivots on which the
lever swings.
Fig. 3. is a section of the disc at the left end of the roller.
In operation the lever C is first placed in position on the two arms, B 2 and B 3
of the right hand carrying bracket, placing the spring C 4 as shown in Fig. 5.
The blind roller is then first placed in the right hand bracket B, the lever C being
pushed down to clear the pawl C 3. from the corrugations. The left end of the
roller is now slipped into the left carrying bracket. The blind cord is now passed
over the roller C1, when this cord is pulled the pawl C3 is taken out of the
corrugations and leaves the roller free to revolve.' Immediately the cord is
released the lever end C 3 engages with the corrugations by means of the spring C 4.
and acts as a brake. If required a cord can also be attached to C 2 in lever by
pulling which the brake action is released and the blind falls with its own weight.
With very heavy blinds both discs of the barrel may be corrugated and the
pawl of the lever extended so as to act as a brake on both.
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.
In blind mountings the use of a disc or discs having waved or corrugated
depressions, together with a pawl fitting into the depressions and acting as a brake
substantially as set forth.
2. In blind mountings the use of a lever C. swinging over the corrugated
disc A 2. and carried by the two arms B2 and B3. The lower arm of this
lever C having a pawl C 3. to fit the depressions in the disc A 2 and the upper arm
having a roller C1 suitably arranged for a cord to run freely over it. The
pawl C3 of the levers lower arm being pressed into the corrugated depressions by
means of a spring, except when released by pulling down the upper arm, sub-
stantially as set forth and described.
