GEORGE SAMUEL MARSHALL of 378 Monument Road Birmingham in the County
of Warwick Brassfounder do hereby declare the nature of this invention to be as
follows:-
My improvements consist in stamping or raising out of sheet metal or by
casting a block made in wedge form projecting at bottom part, and tapering towards
the top part, the back part of said block is open, the front part has a slot about two
thirds from bottom part with a flange on each side of said slot hole at each end of
wedge top and bottom parts are lugs or ears with holes pierced for the purpose of
screwing on to window frame-Inside of wedge I place a cog roller, this travels from
bottom to top-by pulling the cord outwards the said cog roller passes to the top of
wedge and holds the cord or cords firmly in position, in pulling the cord or cords
perpendicularly the cog roller falls to the bottom part of wedge leaving the cord or
cords free to raise or lower the blinds to any given height required.

page_text: 1 GEORGE SAMUEL MARSHALL of 378 Monument Road, Birmingham in the County
of Warwick, Brassfounder. do hereby declare the nature of my said 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 has for its object improvements in cord holders for roller and venetian
and other blinds by which the cord is gripped at any particular point by a simple and
natural movement of the hand or released and allowed to run through without friction
and with ease.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a large sized sheet of drawings upon which
the action of my holder is fully illustrated.
Figure 1 is a front elevation of the holder A attached to the window casing B with
the cord released and passing through the holder.
Figure 2 is a section on line 1. 2 also showing the cord released.
Figure 3 is a similar section showing the movement of the hand in the action of
gripping.
Figure 4. is a front elevation of the holder with the cord secured.
Figure 5 is a similar section to Figure 2, but also shewing the cord secured.
The cord holder is composed of the metallic box A which may be cast stamped or
otherwise raised into the shape shown and is provided with the flanges a¹ and a² 2
enabling it to be secured to the woodwork or casing B of the window or other opening
by means of the screws a³ and at. In the front of the box A the slot a³ is provided
leaving at each side the flanges a and a' which keep the roughed roller or cog
within the holder. The holder may be provided with the metal back as or the
casing B may be left to form the back but in either case a sufficient opening would be
left for the insertion of the roller.
The roughed roller or cog T is placed within the metallic box A so as to move and
revolve up and down the action being as follows:-When the cord is being drawn or
allowed to pass through the holder the roller T falls out of the hollow a' formed at the
bottom of the metallic box A and the cord being perpendicular passes through the
holder A in either direction without interference. To grip the cord it is only necessary
to raise the lower end of the cord as shown by Figure 3 until it reaches the top a¹ of
the inclined front of the box-A at which-point-the-tension upon the upper end of the
cord from the blind draws the roller up until it firmly wedges the cord between the
roller T and the casing B or back as thereby firmly gripping it the release being again
effected by slightly pulling the lower end of the cord down perpendicularly.

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 :-
.
The improvements in cord holders for roller and venetian and other blinds consisting
of the metallic box A fitted with the roughed roller or cog T which wedges and fastens
the cord by its action in the wedge box substantially as herein set forth and shewn
upon the drawings.
Dated this 5th day of July 1888.
