PROVISIONAL SPECIFICATION.
Improvements in Outside Sun Blinds.
1, GEORGE FREDERICK JANES, of 68, Finsbury Pavement, in the County of
London, Window Blind Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in what are known as outside sun-blinds
for ordinary windows, the object of the improvements being to provide a blind
which can be made much cheaper than the ordinary outside sun blinds, and is very
simple in construction.
In carrying out my invention I mount the blind on a roller adapted to be
operated by means of a cord either from the inside or outside of the window.
The front edge of the blind is attached to a lath, which, when the blind is shut,
closes in the roller and forms the front of the box. The outer ends of the pro-
jecting irons are fixed.to the said lath and the inner end of each iron works on a
simple screw or other pivot placed in the centre of the window frame.
By this arrangement the blind can be opened by operating the cord to any
required extent or may be completely let down so as to entirely cover the window,
which is not the case with the ordinary outside blinds hitherto in use.

COMPLETE SPECIFICATION.
Improvements in Outside Sun Blinds.
I, GEORGE FREDERICK JANES, of 68, Finsbury Pavement, in the County of
London, Window Blind Manufacturer, 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:-
This invention relates to improvements in what are known as outside sun-blinds
for ordinary windows, the object of the improvements being to provide a blind
which can be made much cheaper than the ordinary outside sun-blinds, and is very
simple in construction.
In carrying out my invention I mount the blind on a roller adapted to be
operated by means of a cord either from the inside or outside of the window.
The front edge of the blind is attached to a lath, which, when the blind is shut
or rolled up, closes in the roller and forms the front of the box containing the blind.
The outer ends of the irons for projecting the blind are fixed to the said lath and
the inner end of each iron works on a simple screw or other pivot placed in the
centre of the window-frame.
By this arrangement the blind can be opened or let down to any required extent
by operating the cord or may be completely let down so as to entirely cover the
window, which is not the case with the ordinary outside blinds hitherto in use.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is an elevation illustrating the application of my invention to a window-
frame; and,
Figure 2 is a section on the line 2-2, Figure 1 ;
Figure 3 is a sectional view illustrating the oneration of the blind.

page_text: a is the window-frame, and 6 the roller carrying the blind c, the said roller being
supported in suitable brackets d, d and being provided at one end with a pulley e
upon which the cord for operating the blind is wound during the lowering of the
blind in such a manner that when the cord is pulled it is unwound from the said
pulley and lifts the said blind.
9 is the lath or board to which the front edge of the blind is attached and which
when the blind is wound upon the roller serves to cover or conceal the same as
indicated in Figures 1 and 2. h, h are the projecting irons which are pivotted
at i, i at about the centre of the height of the window-frame in such a manner that
the blind, when completely lowered, as indicated by the dotted lines in Figure 3,
will cover the whole of the window.
It will be obvious that the blind can be adjusted at any position intermediate of
its upper and lower positions, for instance, in the position indicated by the full lines
in Figure 3.
jis the stud to which the cord f is attached for holding the blind in any required
position.
It will be noticed by reference to Figure 2 that the pivots i, are placed behind
the axis of the blind in such a manner that when the corf is released, the
weight of the lath and the projecting irons will serve to lower the blind
automatically.
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. An outside sun-blind mounted upon a roller and having its front edge con-
nected to a lath or board carried by projecting irons pivotted at the centre of the
window-frame in such a manner that when the blind is rolled up the said lath or
board will cover or conceal the blind whilst when the blind is lowered the whole of
the window will be covered substantially as described.
2. The manufacture and use of outside sun-blinds substantially in the manner
hereinbefore described and illustrated in the accompanying drawing.
