Improvements in Blind Rollers.
I HENRY BRECKNELL, of Lawrence Hill, Bristol, in the County of Gloucester,
Engineer, 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 invention relates to improvements in the construction of rollers for window or
sun blinds, proscenia and the like, and has for its object the means whereby a blind or
proscenium may be readily and easily attached, or detached, thereto and therefrom
without employing any other agent than those supplied by the roller itself.
In order that my invention and the means I adopt for carrying out the same may
be clearly understood I have appended the accompanying sheet of drawings, in which
Fig. 1 is a longitudinal elevation of my improved roller to which is attached an
ordinary window or sun blind, shewn broken off, and Fig. 2 is a cross section of Fig. 1
upon the line A. B.
In carrying out my invention I employ an ordinary roller A which 1 split or other-
wise equally divide longitudinally for its entire length, care being taken that the
division so made be clean and smooth and free from harass; the two halves or equal
divisions are then placed together and fastened to each other by means of the screws B
embracing each division as shewn by a and a¹ Fig. 2. A metallic grooved wheel C
provided with a projecting stud b is attached to one end of A by means of three or
more screws, shewn by dotted outline at D Fig. 1, in such a manner that said wheel C
embraces both a and a¹ thereby; a circular plate having a projecting stud thereon in
the same manner as the grooved wheel C is attached to a and a¹ in a precisely
similar manner at the opposite end of A, the studs being for suspending the blind
or proscenium upon brackets or the like in the usual way. When it is desirable to
attach the blind or proscenium E to the roller A, the screws B may be partially
withdrawn therefrom, a and a' being still held together at each end by means of the
screws D and the wheel and plate C. a and a may now be sprung apart sufficiently
to admit of the blind or proscenium E being placed between and when adjusted the
screws B are again driven home and the blind or proscenium E held firmly where
placed, the reverse of this operation serving to release E when this is desired, and
in the case of blinds in general use the operation of attaching or detaching E to or
from A may be performed without removing A from its position of suspension. In
the case of large and heavy proscenia and sun blinds the removal of the roller A from
its suspended position generally entails the employment of heavy labour, and with the
rollers as at present made and used this has to be done when a new proscenium or
sun blind is needed, but by the adoption of my invention this is avoided, and can be
performed in the following manner. By removing the screws D from a and with-
drawing two or more of the screws B nearest to C, a and a' may be sprung apart
sufficiently to admit one corner of the proscenium or sun blind E being passed right
through between a and a¹ as shewn in Fig. 2 the replacing of the screw B nearest to C
serves to hold E in that position, and by removing the screws B one at a time and
replacing them in the manner described, the whole of the width of E may be placed
between a and a without removing the roller A from its suspended position, the
screws D being replaced as before. In the case of sun blinds and heavy proscenia
I may use a wheel of any form and size on each end of A as may be
desired.

and in what manner the same is to be performed I declare that what I claim is.
The improved roller for blinds and the like substantially as herein described and
shewn by the appended drawings..
