Improvements in Rollers for Blinds.
1, FREDERIC DAUNT TROWER of Alexandra Terrace, West Cross, Swansea,
Glamorganshire, Gentleman, 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 an improved blind roller, and has for its object to
provide a roller which can be adapted to varying sizes of windows, thus enabling
the roller to be secured properly.
In carrying out my invention instead of fitting the metal notches or sleeves on
the roller in the usual manner, I propose to secure then in such a way that the
roller can be lengthened or shortened to the required amount, so that should the
window be too broad, the roller can be adapted to it, thus preventing any risk of
the blind getting loose, which frequently occurs with the present arrangement. On
one end of the roller, preferably at the end to which the cord is attached, a metali
sleeve is fixed by means of screws or other suitable means. This sleeve is screwed:
externally for the whole or greater part of its length, and the ordinary roller sleeve
carrying the pulley is also screwed internally. The pulley sleeve is fitted to the
roller by screwing, and when the roller is to be lengthened or shortened, the pulley
is simply turned the required amount.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings in which Fig. 1 is a side elevation of a roller.
according to my invention, and Fig. 2 is a longitudinal section of the same.
A is the roller having at one end the cap or sleeve B provided with the usual
central pin or pivot. At the other or winding end the secondary sleeve C is fixed,.
screw threaded externally as above mentioned. On this the cap D carrying the
pulley wheel d is fitted by screwing. To prevent the cap turning accidentally after
it has been screwed into proper position, the nut or ring d¹ is fitted on the sleeve,.
and this is screwed tightly up against the cap, serving as a lock nut. At each end
of the roller the spring E is fitted having a small pin at its extremity. This spring
serves to secure the blind to the roller, enabling it to be fitted in a simple and
effective manner.
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.) An improved blind roller, having a sleeve fitted at one end, screwed
externally, and a metal cap screwed on the said sleeve and adjusted in position,.
substantially as described and for the purposes specified.
(2.) In an improved blind roller, the combination with a sleeve at one
end screwed externally, of a cap screwing it to the said sleeve, and a lock nut.
preventing the cap turning accidentally, substantially as described and for the
purposes specified.
(3.) The improved blind roller, having a screwed sleeve at one end and an
adjustable screwed cap on the said sleeve, a lock nut securing the said cap and
springs for holding the blind in place, substantially as described and shown and for
the purposes specified.
