PROVISIONAL SPECIFICATION.
Improvements in Attachments for Window Blinds.
1, CHARLES STOWELL FARTHING M.A. of Zion House, Kenilworth, in the County,
of Warwick, Gentleman, do hereby declare the nature of this Invention to be as
follows:-
The object of my invention is the construction of an improved form of self-
adjusting devico for securing the endless cords used with the ordinary form of
window blind. The pulley and sliding ratchet device, usually employed for this
purpose, is well known to be unsatisfactory, as it is not self-adjusting and the cords
are generally too tight or too slack.
According to my invention, I affix a small plate to the side of the window casing,
and near the lower end of the cord, provided with a couple of opon eyes or hooks,
through which the cord can be passed, and a suitably shaped weight is hung by means
of an eye, hook, or pulley, to the cord. The aforesaid plate is so placed that the
cord forms a slight anglo in passing through the aforesaid open eyes or hooks, and
the weight is so proportioned that it creates sufficient friction between the cord and
the eyes in the plate and on the weight to hold the blind at any height, and yet
enable it to be readily drawn up or down, while it is obvious that the tension on the
cord will always remain exactly the same, no matter how the cord may vary in
length, through changes in the state of the atmosphere, or stretching in use.
Dated this 2nd day of October 1888.

COMPLETE SPECIFICATION.
Improvements in Attachments for Window Blinds.
I CHARLES STOWELL FARTHING, M.A., of Zion House, Kenilworth, in the County
of Warwick, Gentleman, 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 :-
The object of my invention is the construction of an improved form of self-
adjusting device for securing the endless cords used with the ordinary form of roller
window-blind. The pulley and sliding ratchet device, usually employed for this
purpose, is well known to be unsatisfactory, as it is not self-adjusting and the cords
are generally too tight or too slack.
The accompanying drawing represents in perspective elevation, a portion of a
window and blind with my invention applied thereto.
A is the blind roller, provided with a pulley B in the usual manner. A small
plate C is affixed to the side of the window casing, near the lower end of the blind
cord, and is provided with a couple of open eyes or hooks E, F, through which the
endless cord H can be passed and a suitably shaped weight J is hung by means of an
eye, hook, or pulley, K, to the said cord. The plate C is so placed, that as shown,
the cord forms a slight angle in passing through the eyes or hooks E F and the
weight J is so proportioned that it creates sufficient friction between the cord and
the said eyes, and the eye, hook, or pulley on the weight to hold the blind at any
height and yet enable it to be readily drawn up or down, while it is obvious that the
tension on the cord will always remain exactly the same, no matter how the cord
may vary in length through changes in the state of the atmosphere or stretching in
use.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
In a roller window-blind, operated by an endless cord H, a weight J suspended
by the said cord, and a plate with eyes or hooks E F, arranged to hold the cord at
an angle and create friction, substantially as and for the purposes herein set forth.
