PROVISIONAL SPECIFICATION.
An Improved Blind Cord Holder.
I, JOHN HARRISON, of 9, Wharf Road, Stamford, in the County of Lincoln,
Engineer, do hereby declare the nature of this invention to be as follows :-
My invention relates to an improved holder for blind cords whereby the latter can
be readily held and released.
In carrying out my invention I provide a block having a semi-circular or curved
surface and adapted to be secured to the window frame or other support in any
desirable manner the said block being preferably made tapering so that it is narrower
upon its upper side than on its lower side. To the lower part of the block I pivot
a link or stirrup in such a manner that when turned upwards its free end will
gradually close upon the cord passed therethrough to grip the same between itself
and the block and that when in its lower position the cord or cords can run freely
through the said loop or stirrup.
In practice I find it advantageous to make the loop of such a shape that it will
fit against the sides of the block in any position thus ensuring that the cord or
cords will always occupy a proper position relatively to the said loop or stirrup.
When my invention is to be used in conjunction with the cords of roller blinds I
can if desired form the block integral with one of the brackets carrying the blind,
the loop or stirrup being pivotted thereto as herein before described.
I sometimes arrange in conjunction with the loop or stirrup a spring which
normally retains the loop in its gripping position and to release the cord I attach
an independent cord to the loop for drawing it away from the block.

COMPLETE SPECIFICATION.
An Improved Blind Cord Holder.
I, JOHN HARRISON, of 9, Wharf Road, Stamford, in the County of Lincoln,
Engineer, 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 relates to an improved holder for blind cords whereby the latter
can be readily held and released.
In carrying out my invention I provide a block having a semi-circular or curved
surface and adapted to be secured to the window-frame or other support in any
desirable manner. To the lower part of the block I pivot a loop or stirrup in such
a manner that when turned upwards its free end will gradually close upon the cord
passed therethrough to grip the same between itself and the block and that when
in its lower position the cord or cords can run freely through the said loop or
stirrup.
In practice I find it advantageous to make the loop of such a shape that it will
fit against the sides of the block in any position thus ensuring that the cord or
cords will always occupy a proper position relatively to the said loop or stirrup.
When my invention is to be used in conjunction with the cords of roller blinds
I can, if desired, form the block integral with one of the brackets carrying the
blind, the loop or stirrup being pivotted thereto as hereinbefore described.

page_text: To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which.:—
Figure 1 is a front elevation of my improved blind cord holder; and,
Figure 2 is a horizontal section of the same on the line 2-2:
Figures 3 and 4 are side views of my improved holder with a cord in conjunction
therewith and illustrating its operation:
Figures 5 and 6 are respectively a front elevation and side elevation shewing the
cord holder formed integral with one of the brackets carrying a blind roller.
Similar letters of reference indicate corresponding parts in the several figures.
a is the block having the semi-circular or curved surface b, and c is the loop or
stirrup pivotted upon the said block eccentrically to the surface b so that when the
said stirrup is in the position shewn in Figures 1, 2 and 3, a comparatively large
opening d will be afforded through which the blind cord e can freely pass whilst as
the loop rises the space between the extremity of the opening in the loop and the
surface b will be gradually diminished until the cord will be nipped to hold it as
shewn in Figure 4.
In order that when it is desired to hold the cord the loop shall be readily raised
to the position shewn in Figure 4, the extremity of the aperture of the loop is
made of a V-shape and provided with a relatively sharp edge f on the underside, as
shewn most clearly in Figures 2 and 3, so that when the cord is pulled back from
the position indicated by the dotted lines in Figure 3 into the V of the link, as
shewn by the full lines in the said figure, the weight of the blind drawing up the
cord will also draw up the link to the required position to grip the cord. This
formation of the link renders it necessary to gradually narrow the surface & from
its lower to its upper part, as shewn most clearly in Figure 1, and the said upper
part of the surface 6 has to be of such a width that the point or narrow end of
the V can substantially fit against it.
c², c' are stops for limiting the downward movement of the loop or stirrup.
When my holder is used in conjunction with the furniture of roller blinds, as
shewn in Figures 5 and 6, the block a having the curved surface b is preferably
cast in one piece with one of the roller brackets g and the loop is pivotted thereto
so as to operate in the manner herein described.
I sometimes arrange in conjunction with the loop or stirrup c a spring which
normally retains the loop in its gripping position, in this case, however, I attach an
independent cord to the loop for drawing it away from the block in order to release
the blind cord.
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. A blind cord holder having a block provided with a curved surface and a
loop or stirrup pivotted eccentrically to the said surface in such a manner that in
one position of the loop the cord will be free to pass therethrough whilst in
another position it will grip the cord between itself and the block, substantially as
.described.
2. The manufacture and use of the improved blind cord holder constructed and
operating substantially in the manner hereinbefore described and illustrated in
Figures 1 to 4 of the accompanying drawing.
3. The combination with the furniture of a roller blind of a blind cord holder
substantially as hereinbefore described and illustrated in Figures 5 and 6 of the
accompanying drawing.
