Improvements in and relating to Spring Roller Blinds for Shading
Shop Fronts, and for like and analogous uses.
I. GEORGE PARRY MORGAN, of Mill Lane, Cardiff, Blind Maker, do hereby
declare the nature of this invention to be as follows:-
This invention consists in improvements in and relating to spring roller blinds for
shading shop fronts, and for employment in like and analogous positions.
According to this invention, both of the roller spindles are, for a short, distance
from their extremities, made square or rectangular. Except for the said square or
rectangular parts towards the outer ends, the spindles are round. The brackets or
wall cleats in which the outer ends of the spindles are supported are bridged and
have apertures corresponding in shape with the outer ends of the spindles. On the
inner faces of the end blocks of the rollers are secured hollow bosses of iron or steel
into which are received the collars on the spindles. The hollow bosses have
internally projecting bearings for the spindles. The roller springs are coiled
around the hollow bosses which extend beyond the collars, so that the springs
cannot become jammed between the collars and the bosses. At the outer ends of
the end blocks are fixed bearing rings with apertures to fit the spindles, which, do
not come in contact with the block. The blocks which carry the inner ends of the
spindles are also fitted with ring bearings therefor.
The rollers are placed in position in the manner following. The inner end of
each spindle is inserted in the aperture made for it in the inner block, pertaining to
the said spindle which latter is moved inwards until the springs are sufficiently
compressed to allow the outer end of the spindle to be brought opposite the
aperture in the supporting bracket or wall cleat. The spindle is then permitted to
be returned by the spring and thus shot into the bracket. It is readily unshipped
by inserting a lever behind the outer end of the spindle and, by moving the spindle
inwards, compressing the springs to the requisite degree to free the spindle from
the bracket or wall cleat. The spindles being supported at the various points
above mentioned are thereby steadied in position.

Improvements in and relating to Spring Roller Blinds for Shading
Shop Fronts, and for like and analogous uses.
I, GEORGE PARRY MORGAN, of Mill Lane, Cardiff, 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:
"
1.
..
This invention consists in improvements in and relating to spring roller blinds for
shading shop fronts, and for employment in like and analogous positions.

page_text: According to this invention, both of the roller spindles are, for a short distance
from their extremities, made square or rectangular. Except for the said square or
rectangular parts towards the outer ends, the spindles are generally round. The
brackets or wall cleats in which the outer ends of the spindles are supported are
bridge-shaped and have apertures corresponding in shape with the outer ends of the
spindles.
On the inner faces of the end blocks of the rollers are secured hollow bosses of
iron or steel into which are received the outer collars on the spindles. The hollow
bosses have internally projecting bearings for the spindles. The roller springs are
coiled around the hollow bosses which extend beyond the collars so that the springs
cannot become jammed between the collars and the bosses. At the outer ends of
the end blocks are fixed bearing rings with apertures to fit the spindles, which do
not come into contact with the block. The blocks which carry the inner ends of
the spindles are also fitted with ring bearings therefor.
Referring to the accompanying sheet of illustrative drawings,
Fig. 1 thereof represents in elevation a spring roller blind designed in accordance
with this invention. All the parts are not shown in this view.
At Fig. 2 is illustrated, at an enlarged scale, so much of one end of a spring
blind roller R as serves to illustrate my invention.
Fig. 3 is a part elevation and part section; the springs being absent.
Both ends of the roller R are fitted with spindles, springs and other parts
alike.
Each spindle a is, at the outer end a', made square or rectangular but is otherwise
generally round. The wall cleats are arched or bridge-shaped, as shown. They
are pierced by apertures agreeing in shape with the outer ends a' of the spindles a,
that is to say, square or rectangular. The aperture in the cleat is slightly larger
than the ends a of the spindle a. To the inner face of each end block c is secured,
by screws or otherwise, a hollow boss d of iron or steel surrounding the usual collare
of the spindle a which latter is supported by the boss and by ring bearings f and g
fixed to the end block and the inner block / respectively. i is the usual spring
for rolling the blind. It is fixed, as is usual, at one end to the block c and at the
other to the spindle a. Being out of contact with the collar e, the spring i is
prevented from becoming jammed between the said collar e and the inner face of
the block c..
C
My improved roller is placed in position for use in the manner following. Each
spindle a at each end of the roller R is pushed inwards until the springs i are
sufficiently compressed to allow the outer ends a' of the spindles to be presented to
the apertures in the wall cleats b. The inward pressure on the spindles a is then
withdrawn and the springs i shoot the spindles into place in the cleats b. It will
be seen that, when in place, the spindle a is supported at four places namély
at b, f, d and g. Consequently, increased steadiness of the roller is obtained.
The roller is readily unshipped by applying a lever end to the outer-end of one
of the spindles a and by pressure. inwards compressing the spring i to the degree
requisite to free the spindle end from the bracket or cleat b.
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. In a spring roller blind for shading shop fronts and like and analogous
uses, spindles having at each end square or rectangular journals such as a' (or so
shaped that they cannot turn in the wall cleats or brackets); said spindles being
supported in bearings in the roller, clear of the blocks, at the outer and inner en.ls
of the outer end block and at the onter end of the inner end block, substantially as
hereinabove described with reference to the accompanying sheet of illustrative
drawings.
2. Arched or bridge-shaped wall brackets or cleats such as b for spring roller
blinds; said wall brackets or cleats having square or rectangular openings to

page_text: receive the journals of the roller spindle (or having apertures so shaped as to
prevent the spindle journals from turning), substantially as herein before described.
3. In a spring roller blind for shading shop fronts and like and analogous uses, a
fixed hollow boss or guard such as d surrounding the outer collar of the spindle
and preventing contact of the roller spring with the said collar, as set forth.
