Improvements in Fittings or Devices to be Used in Connection with
Outside Blinds for Shop Windows or for Analogous Purposes.
I JOHN MARSHALL SIDDELL of 80 Dewsbury Road Leeds in the County of York
Blind Maker do hereby declare the nature of this Invention to be as follows:-
My Invention has for its principal object to provide adjustable arms for supporting
shop blinds and the like capable of being extended and contracted as required to
suit different heights of windows and breadths of causeways and it has also for its
object to provide simple means whereby the springs of such blinds may be readily
placed and fixed in position.
According to my Invention instead of making the jointed members of the arms
all in one forged or cast piece so that a particular set of arms has to be made
for each size of window or the like I make the members of the arms so that they
can be lengthened or shortened which I effect by making the joint pieces and end
pieces in separate castings connected by rods or tubes which can be by screwing
or otherwise readily connected and removed so that different lengths of rods or tubes
can be used with the same joints and end pieces I may make the said rods or tubes
fitted to slide within over or against one another so as to expand and contract after the
manner of a telescope or the one portion of the arm may be screwed into the other
portion if desired. A convenient mode of constructing the joint is to form a knuckle
through which is passed a screw. In the male and female portions of this joint I
form a polygonal recess into which I insert a correspondingly shaped nut in which
the screw works so that when the members of the blind arms are adjusted in position
the nut is forced by means of the screw into the recess in the female portion of the
joint and thereby secures the arm in its adjusted position.
To render the springs of such blinds readily adjustable in position I connect the
inner end of the spring to a block provided with a tapered projection fitting a
correspondingly shaped recess or bearing in a block fitted in the interior of the roller.
The block to which the spring is attached is connected by a spindle to a stud passing
through a disc secured to the opposite end of the roller the outer end of the spring
being attached to this disc which inay be secured to the roller by screws or otherwise
so as to be capable of being readily disconnected and replaced the spring being
connected to the disc in the manner described may be readily removed for cleaning
and repairs with ease and facility.
The sections of which the supporting arms are composed may be cranked or
otherwise shaped to suit irregularities in the shop front or surfaces to which they are
applied.

Improvements in Fittings or Devices to be Used in Connection with
Outside Blinds for Shop Windows or for Analogous Purposes.
I JOHN MARSHALL SIDDELL, of 80 Dewsbury Road Leeds in the County of
York Blind-Maker 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 :-
My Invention has for its principal object to provide adjustable blind arms constructed
in sections for supporting shop blinds, sunshades and the like capable of being extended

and contracted as required to suit different heights of windows and breadths of
causeways and so fitted together as to suit irregular or uneven surfaces to which the
arms may be fixed, and it has also for its object to provide simple means whereby the
springs and interior fittings of such blind rollers may be readily placed and fixed in
position.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and for the purpose shall refer to the several
figures on the annexed sheets of drawings. The same letters of reference indicating
corresponding parts in all the figures.
According to my Invention instead of making the jointed members all in one forged
or cast piece or otherwise permanently fixed together so that a particular set of arms
has to be made for each size of window or the like I make the members of the arms
in sections as shown in Figures 1. 3. 4. 5. The sections of the same being 1. 2,
A. B. C and M which may be connected to each other by being screwed, keyed
pinned or otherwise so that any member may be readily connected and disconnected
as the arm is required to be lengthened, shortened, or cranked.
The members 1 and 2 of Figure 1 being hollow I may make them to fit or slide
either within, over or against one another so as to be capable of being extended or
contracted after the manner of a telescope or otherwise as the case may be.
Figure 1 is a Side Elevation of a blind arm constructed according to this Invention.
A is a knuckle joint connecting the members of the blind arms, through the joints
there is passed a partly screwed pin. In the male and female portions of these joints
I form a polygonal recess into which I insert a correspondingly shaped not marked E
Figures 2 and 3 in which the screwed part of pin works so that by turning the screwed
pin the nut is made to traverse inward or outward as the blind arms are required
to be adjusted or locked in position. B Figure 3 shows the same joint fixed to
the wall, pillar, or other supports to which the blind arms are applied.

the blind roller. Figure 4 is one of the methods when the blind arms or members
require to be cranked. In this case I insert the cranked piece marked M.
This is
Figure 5 is an automatic blind arm. The drawing is a Side Elevation of one
method whereby I gain this result, but I do not limit myself to the precise details
and relative positions of parts shown in the drawings as they may be considerably
varied without departing from the nature of my Invention for example Figure 6
shows a method of coupling by means of radial arms and so making the said arms
automatic. Figure 5 shows at A' and B₁ toothed quadrants A coupled by means
of the links A. In this case the members 1 and 2 are fitted within the parts of
the joints marked A³ and B³ and also C.
The said toothed quadrant coupled automatic joint I make so as to be locked in
any required position. On sheet number 3 I show this method. In this case I
have Figure 8 corresponding to Figure 5 in each case A2 are links A are toothed
quadrants working in each other and connected by means of the said links and pins.
In the centre of the links A2 I have a screw E which by a revolution to the right
or left inserts or withdraws a sliding tongue E2 into one of the grooves E³, E*, E5
correspondingly as the blind arms require to be locked or unlocked in a given
position. Figure 8 shows the side elevation of these joints. Figure 9 shows a
transverse section accross the locking screw and tongue and Figure 7 shows the same
joints but without the locking screws and tongue which may be locked with pawl, pin,
or otherwise, it is obvious that I can apply the same joint to the supporting brackets

roller D if required. The hoop G may be fastened to the roller D by means of

tapered projection fitting into a correspondingly shaped recess in bearing L fitted
into the interior of the roller or the bearing L may have on it the tapered projection
fitting into a correspondingly shaped recess in the said block K. Figure 12 L is a
transverse section of the block K. the spring J being attached to the disc F and to
the spindle I or block K and thus with the disc F being fastened to the hoop G the
interior fittings by these means may be readily disconnected and withdrawn from the
roller D or as readily inserted and refastened whereby I have a means of removing
with ease and facility without injury to the roller D the springs and fittings for
cleaning and other purposes.
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
1st. The adjustability of the blind arms by the means and method of constructing
them in sections as hereinbefore described.
2nd. The automatic movement and the method of locking the joints as applied
to blind arms and the like as herein before described.
3rd. The combination as shown in Figure 10 of the winged disc F and hoop G
also G together with the block K and bearing L with tapered projection and
correspondingly shaped recess respectively as and for the purpose hereinbefore
described.
4th. The several combinations and arrangements of the sections forming my
improved blind arms constructed and operating in the manner described and shown
on the drawings.
