We JOHN EMPSON and JOHN HEWITT, both of 58 Graham Street Birmingham in the
County of Warwickshire Manufacturers, do hereby declare the nature of this invention
to be as follows:-
Our invention consists in constructing and arranging in the manner hereinafter
described, brackets for blind furniture, whereby the friction and abrasion of the cord
for oporating the blind is reduced, and its tendency to work off the sheave of the
roller, obviated.
In carrying our invention into effect we construct the bracket of metal with one
part of same arranged for securing to frame of window or casement to which the
blind is to be fitted, and the projecting part to form a support for the pivot or spindle
on the end of roller and sheave in the usual and ordinary manner.
To this bracket we secure a clip or small guide bracket, having a roller small
pulley or revolving pin carried by the side of same, for the purpose of receiving
and guiding the cord to be wound off and on the blind roller sheave; in such a
manner that the cord passing under this small revolving pulley, roller or pin, is held
between the sides carrying the pin and thereby prevented from being pulled over or
off the top or blind roller sheave.
We sometimes construct our bracket without the small guide pulley by forming a
tubular or other shaped guide through which the cord is passed, and this guide we
rivet or otherwise secure or attach to the bracket, in such a manner that the cord has
a long surface guiding it, rather than an edge or narrow ring which causes abrasion ;
and at the same time the possibility of the cord being pulled off the roller is removed
by the bracket and guide being all self contained, and requiring no other or
supplementary fixture for guiding the cord to be attached in connection with the
same.

page_text: We JOHN EMPSON & JOHN HEWITT both of 58 Graham Street Birmingham in the

and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our invention consists in constructing and arranging in the manner hereinafter
described, brackets for blind furniture whereby the friction and abrasion of the cord
for operating the blind is reduced, and its tendency to work off the sheave of the
roller obviated.
In carrying our invention into effect we construct the bracket of metal with one
part of same arranged for securing to frame of window or casement to which the
blind is to be fitted and the projecting part to form a support for the pivot or spindle
on the end of roller and sheave, in the usual and ordinary manner.
To this bracket we secure a clip or small guide bracket having a roller, small pulley,
or revolving pin carried by the sides of same, for the purpose of receiving and
guiding the cord to be wound off and on the blind roller sheave; in such a manner
that the cord passing under this small revolving pulley roller or pin is held between
the sides carrying the pin and thereby prevented from being pulled over or off the
top or blind roller sheave.
We sometimes construct our bracket without the small guide pulley by forming a
tubular or other shaped guide through which the cord is passed, and this guide we
rivet or otherwise secure or attach to the bracket, in such a manner that the cord has
a long surface guiding it rather than an edge or narrow ring which causes abrasion ;
and at the same time the possibility of the cord being pulled off the roller is removed
by the bracket and guide being all self contained, and requiring no other or
supplementary fixture for guiding the cord to be attached in connection with the
same.
In order that our invention may be fully understood and readily carried into effect
we append the accompanying sheet of drawings which we shall now describe.
Figure 1. shows an elevation of the bracket with auxiliary roller guide as
described.
Figure 2. is a plan of the same.
Figure 3. shows the second method of carrying our invention into effect by the
use of a guide tube or channel instead of a pulley.
Figure 4. is a plan of this method.
In figure 1. A is the usual portion of the bracket, B the guide pulley working on
the pin C, the cord D of the Blind Roller E is shown in its proper position in dotted
lines guided by the guide pulley B. The method of preventing the cord from getting
out of the groove in the roller is evident without further description.

page_text: In figure 3 the cord D is shown as passing through a tube F which serves the
same purpose.
In figure 4 the plan is shown.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. The combination of a roller bracket with a guide roller to prevent the cord
slipping off as shown in Figure 1. substantially as and for the purpose herein
described.
2. The combination of a roller bracket with a guide tube as in Figure 3 substan-
tially as and for the purpose herein described.
