JAMES HUDSON of Bolton in the County of Lancaster Joiner " CERTAIN
IMPROVEMENTS IN APPARATUS FOR HOLDING AND RELEASING ROLLER BLINDS'
"
My invention relates to certain improvements in apparatus for holding and
releasing in any required position, the blinds ordinarily suspended from rollers, and
well known as roller blinds.
The roller as usual is provided at one end with an ordinary stud, and at the
opposite end with a double flanged cord pulley and stud, by which it is supported
in position by brackets.
My improvements consist principally in the manner in which the brackets are
made, the one at the cord pulley end is cast or formed with a horizontal slot,
terminating at the inner end with a circular hole, slightly larger in diameter than
the width of the slot, in the bottom of which the roller stud revolves, when the
blind is being raised or lowered. The extreme end of the bracket is provided with
a projecting piece slightly convexed on the inside next to the cord pulley, which
forms a brake for the flange of the latter, and thus holds or locks the blind.
The cord pulley is provided with a cord to enable the blind to be wound up or
down from bottom to top and vice-versa, the bottom end of the blind being
provided also with a short length of cord. When the blind is to be operated upon,
the operator takes both cords, one in each hand, the blind cord is held perpendicular
as well as the winding cord, until the blind has been raised or lowered sufficiently,
when the winding cord is pulled diagonally, or at an angle to the perpendicular
line of the cord when winding, which action causes or pulls the cord pulley stud
into the horizontal slot, and brings the outer flange or rim of the cord pulley
against the convexed projection on the bracket, thus locking or holding the blind
in position, where it remains until it is desired to be altered, when the operator
takes hold of the cords as previously described, and pulls at the blind cord, which
action rolls the cord pulley stud into the circular end of the slot, when it can be
either raised or lowered at will, and so on. The bracket at the cord pulley end is
so constructed, as to enable it to be used for either right or left hand, and can be
hung vertically, as well as horizontally, the base being provided with screw holes to
allow it to be fixed to the window casing or other convenient position near the
window.

page_text: The bracket at the opposite end of the blind roller is made with a semi-circular
hole or slot, slightly larger than the roller stud, to allow of the diagonal motion of
the blind and roller when the cord pulley stud is pulled into the horizontal slot, in
the bracket at the opposite end. This bracket is so constructed and formed at the
outer end, as to enable it to act as a preventitive against the stud or blind being
pulled out of the semi-circular hole or slot by the action of the winding cord when
pulling side-ways. On the inner side, is formed an angular slot or passage for the
roller stud to pass through when being removed from. the suspending brackets. In
the projecting end is formed at right angles to the perpendicular line of the blind,
a semi-circular hole which acts as the bed for the roller stud to revolve in, when
the bracket is hung vertically and not horizontally, as is usually the case.
bracket is provided with a base plate with screw holes provided top and bottom, to
enable it to serve for either right or left hand, as well as being hung vertically or
fixed horizontally.
This
The novelty of this invention is, that it dispenses with many intricate parts
already in use; such as, racks, ratchets, levers, cord guides and such like contri-
vances; also that it is applicable for either right or left hand without any
alteration, at the same time can be hung either vertically or horizontally.
Another feature is its simplicity, which fulfils a requirement long felt, with
cheapness combined. ...
