PROVISIONAL SPECIFICATION.
Improvements in Window Blind Appliances.
ALFRED GOUGH 10 Wedmore Gardens Upper Holloway London Commission
Agent do hereby declare the nature of this invention to be as follows:-
My improvements relate more particularly to the construction of the brackets
or hooks which are fixed to the window frame for carrying the roller. The
brackets or hooks are made of spring steel & the circular spring part is made
somewhat smaller than the turned ends of the roller, so that it will grip the roller
sufficiently tight to hold the roller in any position required. The raising &
lowering of the blind is effected by simply drawing the blind down or drawing it
up by the single cord which may be attached at either end.

Improvements in Window Blind Appliances.
I, ALFRED GOUGH, of 10 Wedmore Gardens, Upper Holloway, London, 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 a spring band like appliance to embrace an enlarged
or reduced end of a window blind roller, and exert frictional contact thereon to
bold the blind at any desired elevation, the appliance having a back or side plate
for attachment to the sash frame.
My invention will be clearly understood by reference to the annexed drawings.
Figure 1 perspective elevation of a spring clip appliance, say for the left hand
cud of a blind roller.
Figure 2 a similar view of, say a right hand end of a blind roller.
Figure 3 elevation of roller end and cord pulley.
Figure 4 detached view of separate end and pulley with screw dowel pin for
fixing to roller.
A is a segmental springy band or clip with a turned down end B for facilitating
the easy fixture and removal of a blind roller by simply thrusting the roller end,
such as C, into the hollow D of the spring clip A, said hollow being of slightly
smaller diameter than that of the end C as to grip the end sufficiently tight to hold
the blind at any elevation or position at a window.
The clip appliances, Figures 1 and 2, which are approximately of the same shape
as a pair have a back tang E and a depending plate of greater width than the
clip portion to allow of its fixation to a sash frame by a screw or nail passed into
the hole G.
The pulley H on either or on both ends C of the roller J, Figure 3, is of
sufficient width and depth in the "whorl " for the necessary wrappings of the blind
raising cord, the free end of which may hang loose.

page_text: I prefer that the pulley or pulleys be bored through the body, as at K, for a
cord to be passed into from one part, and then when a knot is made, the cord cau
be drawn back for the knot to be located in the larger portion of the bored hole to
leave the "whorl " clear for the regular wrapping of the cord therein when the
blind is being pulled down.
In most cases, window blinds are raised to a given height from day to day, so
that when the grip or clip of the appliance on the ends of the roller is once set, the
blind remains secure, the setting being effected by pinching the band A to be in
close contact with the roller end to obtain the required frictional grip when the
roller is first fitted in.
I prefer that the ends be of large diameter compared with the present form of
pintle or pin and of wood as extensions of a roller on to which the pulleys can he
nailed from their flat sides, but the pulley or pulleys can have the enlarged sized
ends or otherwise, as desired.
It will be understood from the drawings that the segmental springy band A is
of less width than the plate F to give room for the operation of a screwdriver or of
a hammer when the appliance is being fixed in position.
I have referred to the appliances being in pairs but if made of sufficient strength
one only need be used, the opposite end of the roller having the usual pintle or pin
with an ordinary bracket.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The employment of an appliance constructed as shown on the drawings for
frictionally gripping the end of a blind roller and acting as a retainer of the blind
at any elevation, as set forth.
2. The employment of enlarged or reduced ends to a window blind roller and
the gripping of same by spring clip baud like appliances affixed to and projecting
from a sash frame as described and substantially as represented in or by the
anuexed drawings.
