PROVISIONAL SPECIFICATION.
An Improved Automatic Stop or Detent for Blind Rollers and other
Rotating Parts Worked by a Single Cord or Rope.
I, WILLIAM MERRALL SIMONS, of No. 8, Clinton Terrace, Sherwood Street, in
the Town and County of Nottingham, do hereby declare the nature of this inven-
tion to be as follows;-
:-
My invention consists of an angular or ✓ shaped lever, pivoted at the angle
upon the bracket, or bearing, upon which ja cord-reel rotates or revolves; the
angle being downwards, so that the end of the rear arm of the lever shall engage
with the flange of the said reel, which is square; the forearm of the said lever
projecting beyond the reel, to which one end of the cord is secured, and upon which
it is wound. A grooved wheel or pulley, at the end of the lever receives the cord;
by which, on being pulled in a downward direction, the forearm of the lever moves
upwards disengaging the rear-arm of the same from the flange of the reel, which
is free to revolve; the action being reversed by the weight of the blind, or other
object disharging itself from the roller, shaft, or drum to which the reel is
attached, the tightening of the cord, holding the lever back, which falls of its own
weight when the cord relaxes, and reengages with the square flange of the reel at
any point that may be desired.

I, WILLIAM MERRALL SIMONS, of No. 8, Clinton Terrace, Sherwood Street, in
the Town and County of the Town of Nottingham, Commission Agent, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
-
I will proceed to describe the nature of my invention as applicable to roller-blind
furniture, to which I think it is especially adapted, and may be most clearly and
universally understood and easily and intelligably explained.
To the ordinary blind-roller, I attach at one end, a square roller-end, or reel, or
pulley A having a deep groove, resembling the reel of a fishing rod.
To the inner side of one of the brackets, or bearings B which support the roller I
רנס..."

page_text: attach a V shaped or triangular lever C, by a pivot at the bottom angle of the same,
on to the lower portion of the said bracket or bearing, so as to freely swing or rock
upon its pivot.
When actuated by the cord, the lever, C the rear upper angle of which is in
contact with, and immediately under the off angle of the square reel A, (preventing
the running down of 'the blind) recedes by an upward movement, disengaging
itself from the reel, when the blind will descend of its own weight, charging the
reel with sufficient cord to again raise the blind. To the foreangle of the lever C
I attach a ring or eye D with, or without a small roller attached, through which the
cord, having been previously fastened to the reel by one end, is passed:
The operator may raise or lower the blind to any point constituting one fourth of
a revolution of the roller, by simply pulling the cord in a downward direction to
raise the blind, keeping the cord in hand to lower the same, and letting go the cord
to stop the blind, at any point that may be desired the lever automatically per-
forming that work.
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:
―:
1. The square pulley or reel.
