PROVISIONAL SPECIFICATION.
Improvements in or relating to Blind Rollers.
I, THOMAS PILL of Wargrave Road Earlestown, in the County of Lancaster,
Plumber, do hereby declare the nature of this invention to be as follows :-
This invention relates to blind rollers, and the object of this invention is to
afford a convenient means of fixing a roller blind at any height and releasing the
same instantaneously.
In this invention I construct brackets such as a on the accompanying drawing
into which the ordinary form of pins in the ends of a blind roller c are fitted :
I place on one end of the aforesaid roller c an india rubber band d. I pivot a
lever as e to the bracket a by means of the pin f the lower end e¹ of said lever
being placed back out of the centre line y of the roller c. The upper end e² of
the lever e will rest against the aforesaid india rubber d: I attach a cord h to the
roller c so as to wind in a groove formed in the end of the roller c and pass said
cord through a hole in the lower end e' of the lever e; by these means when the
cord h is pulled in order to raise the blind, said blind cord will draw the lower end e¹
of the lever e towards the ceutre line g and thereby raise the upper end e² of said
lever from contact with the india rubber band d. When the cord is released the
upper end of said lever will again fall against the india rubber band d and act as
a break to prevent the roller rotating unless the blind is pulled forcibly.
In order to prevent noise, I insert an india rubber pad in the bracket at the end
of the roller.

Improvements in or relating to Blind Rollers.
1, THOMAS PILL, of Wargrave Road, Earlestown, in the County of Lancaster,
Plumber, 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 :-
This invention relates to blind rollers, and the object of this invention is to
afford a convenient means of fixing a roller blind at any height, and releasing the
same instantaneously.
I attain this object by the means hereinafter described and as illustrated in the
accompanying sheet of drawings, in which
Figs. 1 and 4 are side views, and Fig. 2 a front view of a bracket constructed
according to my invention for supporting a blind roller.
Fig. 3 shows my invention applied.
In these views similar letters refer to similar parts.
In this invention I construct a bracket such as a on the accompanying drawing,

page_text: 1
and fit said bracket to a window frame on the cord side of a window blind roller:
the pin 6 on the end of the blind roller c is fitted into said bracket, the opposite
end of the blind roller being supported by a bracket as a¹ of ordinary construction.
I place a friction roller or pulley d on the end of the blind roller near the
bracket a said friction roller being formed of or covered with india rubber, leather
or other material that is non-slipping: I pivot a friction lever as e to the bracket a
by means of the pin fin such a position that the lower end e' of said lever will be
set back from an imaginary centre line represented by g drawn vertically through
the centre of the roller c in Fig. 1. By the force of gravitation the lower end el
of the lever e will cause the upper end e² to rest against the friction roller d. I
attach a cord to the blind roller c and pass said cord through a hole in the lower
end e¹ of the lever e: by these means when the cord is pulled in order to raise
the blind, said cord will draw the lower end e' of the lever e towards the centre
line and thereby raise the upper end e² of said lever from contact with the
friction roller d as shown in Fig. 4 on the drawing.
When the cord is released the upper end e² of said lever will again fall against
the friction roller d and act as a break to prevent the blind roller rotating unless
the blind is. forcibly pulled.
To prevent noise I insert an india rubber pad for the pin b in the brackets at
the ends of the roller.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed I declare that what
I claim is :-
1st. In a bracket for supporting a blind roller, the combination therewith of a
gravitation friction lever as ; substantially as and for the purpose herein before
⚫ described..
2nd. In a blind roller, the combination therewith of a friction roller or pulley
as d and a gravitation friction lever as j for the purpose and in the manner
substantially as herein before described.
Dated this 8th day of December 1894.
