PROVISIONAL SPECIFICATION.
Automatic Blind Mountings for Holding a Window Blind in its
Place when Drawn up to its required Height.
JOHN BROWNRIGG of Windermere in the County of Westmorland Joiner do
hereby declare the nature of this invention to be as follows:-
My invention is composed in the following manner an ordinary socket, with a, cord,
barrel, is fixed on the blind roller, and with an axle to run in a, plate bracket, a solid
metal wheel, with beviled edge, is screwed on the axle against the barrel, the bottom
of the bracket has a beveled projection, sloping downwards against the plate and on
which the beveled edge of the wheel rests, thus procuring an automatic, self acting
brake, and by drawing up the blind with a cord passing over a small pulley, slightly
raises the wheel from the brake, a thin piece of leather is placed between the wheel
and bracket to render the motion noiseless. The novel parts are simply the wheel
and brake used as above described, no spring is required to grip the cord and cause it
to break through constant wear, no screw is required at the opposite end, which
frequently requires tightening, nor the troublesome toothed rack and catch.
Superior action is secured at a great saving in cost.

I JOHN BROWNRIGG of Woodside, Windermere in the County of Westmorland
Joiner and Builder, 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 :-
My improvements are in mountings for a window blind roller which by the friction
of its own weight resting on a fixed brake holds the blind in its place when drawn up
to its required height-I here give reference to the accompanying sheet of drawings.
Fig. 1. represents the end of a blind roller, socket A and barrel B which receives the
coiled cord for drawing up the blind, the solid bevelled wheel with axle pin D
revolves in the bracket E with the axle hole made for the wheel to rise and fall on
the brake at F, the cord passes over the pulley H and, when drawing up the blind,
lifts the wheel from the brake and reduces the friction against the cheek of the
bracket which has a thin leather washer to render the action noiseless-Figs. 2 and 3
are side elevation and section of the bracket E which can be fixed either at the top or
back as shewn by the screws-By my improvements the cord can be drawn in any
direction without getting out of its place-No spring is required for holding the cord
which so soon wears it away.
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 use and employment of the bevelled wheel C.
2. The fixed brake F in combination with the bracket E in manner and for the
purpose substantially as herein shewn and described.
