page_text: 1 also provide an adjustable bearing consisting of a revolving plate or disc and
stud or pin P working in the slot M of the bracket and having a number of
grooves QQQ in its periphery, of various depths, so as to form bearings for the
centre-pins For H to turn upon, the latter being further held in place by the sides.
of the fork or slot M. The bearing-plate O at one end of the roller, may be
provided with holes Q. Q. Q, instead of grooves at various distances from the
centre of said plate; thus it will be seen that the pins F and H of the roller can be
raised and lowered and held at various heights in the slot or fork of the bracket L.
A single cord R is shown passing around the pulley E so that on pulling the cord,
the same becomes unwound from the pulley and at the same time draws up the
blind. In order to grip or retain the cord in position when the blind is wholly or
partially raised, I form a plate or box S with turned-up edge or side T against
which the head of a small lever or eccentric U normally bears, the same being
pivotted at U', and weighted at its other end or provided with a spring U or other
equivalent means, so that the cord R will be allowed to move easily in a downward
direction, but its tendency to move upwardly is overcome by reason of the lever or
eccentric U binding against the cord, which becoming wedged, will only be able to
move upwardly again when the head of the lever or equivalent is released
by hand.
At one end of the portion A of the roller, I make a small recess V, and I may if
found necessary, especially in the case of long rollers, make one or more holes or
slots W passing into the groove or channel C and corresponding holes X in the
rib D of the other portion B of the roller, so that by inserting a wire or pin Y
through holes W and X after the two portions of the roller have been pressed one
against the other, I may cause the same to be held more firmly together, or I may
provide other means for this purpose such as a spring-clip or ring Z passed over the
roller when completed.
The method of securing the blind to the roller is as follows:
The portion B of the roller being removed, the blind A' is secured temporarily
by one corner to the portion A by means of a pin V₁ or the like pressed into the
recess V, the other corner of the blind is then raised to the proper height and the
tongued portion B of the roller is pushed under the collar of the pulley E, the rib 1)
entering the groove C.
The two portions A and B are then pressed firmly together, the extreme end of
the latter passing through the notched or cut-away portion J of the ring I which
is now turned through part of a revolution, thus binding the two portions together
into one complete roller. If found necessary, the wire or pin Y may now be
inserted for keying the two portions at a point or points between the ends and thus
provide greater security.
It will be found that a roller constructed as described will exert a firm binding
power upon the blind and renders the use of tacks, nails or other means likely to
injure the material, quite unnecessary.
The double or composite roller before described, may also be applied to or
adapted for binding any flexible material. requiring to be held, stretched, or
suspended for any similar purpose.
The bracket L and adjustable bearing O, and also the means for gripping
the blind cord, may be applied to blinds or the like of ordinary or other
construction.
The separate portions of the roller may as an alternative, be provided with
pins and corresponding recesses in place of the grooves and tongues above
described.
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. For holding, stretching, or suspending cloth or other flexible material for
roller blinds and similar purposes, the employment of a roller made up of two or

page_text: more longitudinal portions, the meeting surfaces being grooved and provided with
corresponding ribs or laths, or furnished with pins or projections and corresponding
holes, for the purpose of obtaining greater binding power, substantially as herein-
before described with reference to the accompanying drawings.
2. A roller composed of two or more longitudinal portions A and B held together
at one end by a collar or ring, and at the other end by means of a notched ring I
capable of being turned, as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
3. For regulating the height of a roller upon its brackets, the use of a revolving
plate or disc O having grooves or holes therein, substantially as and for the purposes
hereinbefore described.
4. For holding the cords of blinds in tension, a device such as described in the
foregoing Specification with reference to Figures 1 and 9 of the accompanying
sheet of drawings.
5. The improved roller-blind consisting of a roller divided into two or more
parts A and B having a groove or channel C and rib or tongue D or their
equivalents, for containing or holding the edge of the blind A¹, in combination
with the securing ring 1, the pin or wire Y, tail-plate G and pulley E, the
whole substantially as herein set forth and as illustrated by the accompanying
drawings.
