Improvements in Window Blind Rollers.
ROBERT BOLTON Gentleman of 67 Shaftesbury Road Ravenscourt Park West
and EDMUND FITZMAURICE LACKERSTEEN Gentleman of 7 Aunondale Road
High Road Chiswick London West, do hereby declare the nature of this invention
to be as follows':—
For fastening blinds to window rollers without the use of screws nails or sewing
and for detaching same at leisure. The roller consists of two parts, the larger
section having a longtitudnal groove the whole length of the same and into which
the smaller sections fits acurately so that when both sections are combined, forms.
a complete roller. The larger section having in the centre of the longtitudnal
groove a rise or elevation terminating and shaped like a triangle or the half of a
square cut in two from one angle to the other, so as when placed together these
angles form a square, the smaller section of the roller has a corresponding groove
which when placed in its respective position forms a complete roller, while at the
same time grips the blind material between the sections at such an angle as to
render it secure. 1 claim the right to use the the groove either in a round square,
elongated or triangular shape, and may be used and made in any suitable material..
The blind may be placed over the larger section, and secured by the smaller
section being placed in its respective position over the material which prevents the
pressure on the blind from removing it when pulled from its proper position or it
may be used solely on the smaller section of the roller or by & between both
sections so as to give a uniform teusion to the blind.

Improvements in Window Blind Rollers.
Wc, ROBERT BOLTON of 67 Shaftesbury Road Ravenscourt Park West
Gentleman and EDMUND FITZMAURICE LACKERSTEEN of 7 Annondale Road
High Road Chiswick Loudon W., Gentleman do bereby 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:—
Our invention relates to improvements in the construction of blind rollers
whereby blinds may be promptly and securely fixed to their rollers without
stitching, tacking or nailing such as hitherto practised.
In carrying our invention into practice we cut out and detach from a blind roller
throughout its length a longitudinal strip or bead having a triangular, square or
other suitable sectional shape in such a manner as to leave in the roller a recess of
corresponding shape wherein the strip or bead can be snugly located and secured
in that position by the end fittings of the blind roller.

page_text: In the accompanying drawings wherein like letters of reference indicate
corresponding parts,
Fig. 1 is a plan of my improved roller with the strip or beads shown
separately below the same, Fig. 14 being a cross section on line of Fig. 1.
Figs. 2 and 24 are corresponding views of a modification of my invention,
Fig. 2 being a cross section on line y y of Fig. 2.
Fig. 3 is a diagrammatic view showing the blind in position i.e. fixed to a roller
of our improved construction.
As shown in the drawings a strip or beads is detached from the roller r
throughout its length, this bead having a square shape as shown in Fig. 1ª, or the
shape shown in Fig. 24. By thus cutting out a strip or beads a recess having a
shape corresponding exactly to that of the bead (Fig. 14 and 2^) is formed in the
roller while a certain amount of play is permitted between the recess and the bead
in order to allow for the thickness of the blind as hereinafter more fully set forth.
To attach the blind B to the roller r Fig. 3. the upper edge of the same is laid
in the recess i and the bead or strips having been placed over this edge into the
same recess, the ends of the roller and of its strip are secured together by the
wheel w and the fitting f; the blind being now tightly held by the strip throughout
the length of the roller so that the former can be safely and conveniently pulled
up and down for use.
Instead of laying the upper edge of the blind in the recess we may place it
Or in some cases
around the strip and secure the latter as before into its recess.
we may slip the strip through the loop usually formed at the upper edges of blinds
and place the strip into the corresponding recess in the roller, the wheel w and the
fitting securing together in all cases the two ends of the roller r and of its
strip 8.
It is obvious that although we have only illustrated two forms of strips, we may
use strips of circular or of any other suitable shape.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In the rollers of blinds the cutting out, from the roller, of a longitudinal strip
of any suitable shape and the formation of a corresponding recess wherein the
latter is located for the purpose of fixing a blind interposed between the roller and
its strip, substantially as herein described and shown.
2. The improved roller blind constructed and operating substantially as herein
described & shown in Figs. 1 and 1ª of the drawings.
3. The improved roller blind constructed and operating substantially as herein
described & shown in Figs. 2 and 2ª of the drawings.
Dated this 20th day of July 1895.
