PROVISIONAL SPECIFICATION.
Improvements in Roller Racks for Blinds.
We, FRANK BARKER, Brassfounder, of 11 James Street, in the City of
Birmingham, and SAMUEL BOTT, Hardware Merchant, of 286 Lichfield Road,
Aston, in the County of Warwick, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to roller racks for blinds and its object is to produce a
simple, effective and easily manufactured roller rack.
Our invention consists in a new arrangement of roller rack so designel as to be
capable of manufacture from sheet metal.
In one method of carrying the invention into effect we construct a rack which
consists of a brass strip cranked at both ends and perforated along its raise part
with a number of slots; these slots form the rack. On the rack we mount a slide
made from sheet metal, which slide has four bent over lugs, two at each side which
engage the edges of the rack piece and cause the said slide to be firmly attached to
the rack while capable of being moved up and down. We form lugs on this sheet
metal sliding piece and hend them upwards. Through these lugs we pass a pin
and on it mount the blind cord roller. We place the roller within a hinging piece
also formed of sheet metal. This hinging piece is made by cutting out a central
slot in a flat metal plate and bending over the plate so as to encircle the pin
carrying the roller. One end is turned up to form a finger or grip piece and the
other, iuner end, is turned in to form a hook ended piece; the hook engages in one
of the slots herein before described in the rack and the slide can be set at any
particular position on the rack and the hook engaged to hold it there.
We preferably construct our improved roller blind rack in brass; the roller also
may be of brass, but earthenware or other material may also be used for its
construction. The pin passing through the hinging piece and roller may be of
iron or steel.
Holes are provided in the cranked over ends of the rack plate for the purpose of
attaching to the window frame.
Improvements in Roller Racks for Blinds.
We, FRANK BARKER, Brassfounder, of 11, James Street, in the City of
Birmingham, and SAMUEL BOTT Hardware Merchant, of 286, Lichfield Road,
Aston, in the County of Warwick, do hereby declare the nature of this inven-
tion 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 roller racks for blinds, our object being to produce a
simple but effective roller rack, having a more ready and convenient means for

page_text: adjusting and securing the roller than exists with the roller racks of the ordinary
construction.
In order that our invention and the method of carrying the same into effect may
be the more readily understood, we append hereunto one sheet of explanatory
drawings, to be hereinafter referred to.
Figure 1 is a front elevation, Figure 2 a side elevation, and Figure 3 a plan
representing our complete roller rack.
Figure 4 is a plan of the slide showing the side lugs for bending upwards or
outwards into position for carrying the roller pin.
Figure 5 is a front elevation, and Figure 6 a side elevation of the hook or catch
piece for hinging to the roller pin.
Figure 7 is a front elevation of the rack plate.
The same reference letters in the different views indicate the same parts.
We cast or otherwise produce the rack plate A from a brass or other metal,
cranking it at both ends, as illustrated, and perforate its raised part with a number
of slots forming the rack. On the rack plate we mount a slide B made from sheet
metal and having four bent over lugs such as b, two at each side, which embrace
the edges of the rack plate, and cause the said slide to be firmly attached to the
plate while capable of being moved up and down. We form side lugs such as b²,
on the sheet metal sliding piece B, and bend them upwards, and through such bent
up lugs we pass a pin C, and on it mount the blind cord roller D. We place the
roller D within a hinging piece E, which is preferably made by cutting a slot or
aperture in a flat metal plate, and bending over the plate to a form such as shown
at Figures 5 and 6 suitable for hinging to the pin C, carrying the roller D.
end of the hinging piece E is turned up to form a finger or grip piece e, and the
other end is turned or bent to form a hook ended piece e¹. This hook or catch e¹
engages in one of the slots hereinbefore described in the rack, and the slide can be
set in any particular position on the rack, and the hook engaged to hold it there.

We preferably construct our improved roller blind rack in brass; the roller also
may be of brass, but earthenware or other material may also be used for its
construction. The pin passing through the hinging piece and roller may be of iron
or steel or other suitable metal.
Holes such as F are provided in the cranked over ends of the rack plate for the
purpose of attaching to the window frame.
We do not limit the application of our invention to any particular form or pattern
of rack plate, or of the roller slide with the hook or catch piece hinged thereto,
but make such modifications as may be necessary to suit varying requirements.
•
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. The construction of metal roller racks for blinds substantially as herein before
described, and as illustrated in the accompanying drawings.
2. In roller racks for blinds the use of a slide having a hook or catch piece hinged
thereto, substantially as and for the purposes herein before described, and as
illustrated in the accompanying drawings.
3. In roller racks for blinds the combination of a slide having a hook or catch
piece hinged thereto, with a rack plate substantially as and for the purposes
herein before described, and as illustrated in the accompanying drawings.
