PROVISIONAL SPECIFICATION.
Improvements in Window-blind Fittings.
I, WILLIAM HENLEY of 30 Camplin Street, New Cross, London, Metal
Plate Worker, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in window-blinds fittings and has for its.
object a means whereby the tension in the blind cord may be taken up, thus.
preventing the breaking of said cord.
For this purpose I use a spiral spring of iron, brass, steel, or other suitable wire,.
baving a loop at each end.
I also arrange a suitable clip fitted with a small pulley. One of the loops.
aforesaid of the spring is passed through this clip, where it is held in position.
In operation the clip is detached from the spring and the cord passed through.
same onto the pulley. The clip is then attached. A nail, screw, or other suitable.
object is fixed to the window guide and the other loop on the spring passed over-
this nail or the like.
It can be readily seen that any tightening in the cord compels the spring
to lengthen thus preventing undue stress on the cord.
Dated this 19th day of April 1895.

Improvements in Window-blind Fittings.
1, WILLIAM HENLEY, of 30 Camplin Street, New Cross, London, Metal Plate
Worker, 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 of improvements in window-blind fittings has for its object the
production of a simple, cheap, durable and effective means whereby the tension in
the blind cord is automatically taken up, thus entirely obviating any necessity for
shortening the cord consequent upon its stretching under constant use.
In accordance with my improvements I dispense with the well known window
blind "rack pulley" and instead thereof I employ a spiral spring of iron, steel,.
brass or other suitable wire, having a loop at each end. One of these loops.
is passed through a suitable clip hook, which latter is fitted at the top with a small
grooved pulley.
One of the loops of the spiral spring aforesaid is entered through the lower
end of the clip hook, where it is held in position as shewn in the accompanying
drawing, referring to which,
Figure 1 shews an elevational view of my improved window blind fitting, with the
spiral spring in its normal condition of compression.
Figure 2 is a corresponding view to Figure 1, but shewing the spring

page_text: The manner of using my improved device is as follows:-The clip hook 6 having
been detached from the top loop d of the spring e, the blind cord is fitted round the
pulley a; the spring e is then extended and assumes the position shewn Figure 2;
over extension being prevented by the employment of a limiting chain for the like,
secured to the two ends of the spring e, a brass headed nail or other suitable means
of attachment is driven through the bottom loop g into the window frame, and on
which nail or the like, the bottom loop is held. The top loop d being entered through
and taking its bearing upon, the clip hook aforesaid at c.
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,
The improved window blind fitting substantially as herein set forth, in
substitution for the ordinary window blind "rack pulley."
