Improvements in and connected with Rollers for Window
Blinds.
1, GEORGE FREDERICK BRADBURY of 9 Borron Street, Portwood, Stockport,
Joiner, do hereby declare the nature of my said invention to be as follows :-
This invention consists of an improved attachment or regulator for the rollers of
window:blinds to prevent the blind fabric running "askew "when raised or lowered as
heretofore and so cause the same to be evenly wound on the roller at each end.
The improved regulator consists of a narrow strip of sheet iron, brass steel or other
suitable material rigidly affixed at one end to the smaller or diminished end of the
roller but at its other end left free and bent slightly outwards so as to project
beyond the surface of the roller.
By means of a screw capable of screwing into the roller and passing through a
hole in the free end of the regulator I am enabled to readily increase or decrease the
circumference of the roller to the greatest nicety and so cause the blind fabric to
run true when raised or lowered and be evenly wound on the roller.
I sometimes provide the adjusting screw with a nut or washer so that the
regulator may be held between it and the head of the screw and so be caused to
follow the screw whether it should tend to do so or not.
Dated this 16th day of March 1891.

I, GEORGE FREDERICK BRADBURY of 28 Werneth Street Carrington Road
Stockport Joiner late of 9 Borron Street Portwood Stockport 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 window blind rollers, and consists of an improved
attachment or regulator for the rollers of window blinds to prevent the blind fabric
running askew when raised or lowered as heretofore, and so cause the same to be
evenly wound on the roller at each end. The improved regulator consists of a
narrow strip of sheet iron brass steel or other suitable material rigidly affixed at
one end to the smaller or diminished end of roller but at its other end left free
and bent slightly outwards so as to project beyond the surface of the roller.
By means of a screw capable of screwing into the roller and passing through a
hole in the free end of the regulator I am enabled to readily increase or decrease
the circumferance of the roller to the greatest nicety and so cause the blind fabric
to run true when raised or lowered and be evenly wound on the roller. I some-
times provide the adjusting screw with a nut or washer so that the regulator may
be held between it and the head of the screw and so be caused to follow the screw
whether it should tend to do so or not. Now suppose (a) on drawing to be the
roller (b) regulator (c) adjusting screw (d) screw to fasten regulator on roller now
suppose the blind is running askew at the end (e) that is to say when your blind is
wound up it hangs lower at end (e) than it does at end (f) by raising the adjusting
screw (c) it will cause that end of roller to take up more blind fabric as you have
increased circumferance of roller at that end drawing shows 2 regulators on roller
DC21

page_text: but only one in use at end (e) so no matter what side your blind runs askew you can
readily adjust it by raising the adjusting screw (c) and so cause the same to be
evenly wound on the roller
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
To increase or decrease the circumferance of roller by means of a narrow strip of
iron steel brass screws or any suitable material at the end where blind is running
askew it will so cause the same to be evenly wound on roller.
