I, JULES HIPPOLYTE CHOLET, of 41, Rue Taitbout, Paris, in the Republic of
France, 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:-
This invention relates to a novel arrangement of curtain rods which allows large
curtains to be drawn or pulled back as required without the use of cords. This
arrangement also allows the curtains to be instantaneously put up or taken down
without it being necessary to unmount the arrangement or apparatus which when
once fixed to the wall never requires to be removed.
This apparatus is composed of two rods one of which is smooth and the other
twisted and of two movable nuts which travel to and fro upon the twisted rod.
This twisted rod is divided into two parts twisted in opposite directions and is
mounted in supporting studs or brackets driven into the wall. It is provided at
one end with a toothed pinion over which is placed a chain passing down along
the wall and over a roller mounted in a bearing carried by a regulating screw fixed
to the wall.
According as one or other branch of the chain is pulled, the curtains, which
follow the movement of the nuts, to which they are fastened at their inner ends
by means of screws are drawn to and fro.
The apparatus is represented in the annexed drawings in which:
Fig. 1 is a rear elevation of the said apparatus.
Fig. 2 is a side elevation of one of the studs or brackets.
Fig. 3 is a side elevation of a nut with its fastening screw.
a is a window curtain shown drawn, the other curtain is not shown.
b is a fixed smooth curtain rod resting upon the brackets and upon which the
curtain is hung by means of rings threaded on it.
d is a curtain rod twisted in two directions and mounted upon the brackets e.
Upon this rod two nuts f, g, travel to and fro when the chain is actuated.
This chain passes over a pinion i fixed at one end of the twisted rod, also over
a roller j rotating in a bearing k carried by a screw rod m passing through the
piece which is fixed to the wall and which allows the tension of the chain to be

is screwed on after the curtains are in place. This pin serves as is shown to make
the curtain fast to the side of the bracket.
It is easy to understand the action of the apparatus. When once the curtains
are in place, according as one or other branch of the chain is pulled, the twisted
rod rotates in one direction or the other; this movement of rotation causes the
nuts to slide to and fro upon this rod taking with them the curtains which are
drawn to or fro as required.
This very simple mechanism thus allows the use of cords which are easily
derangible and rapidly worn out to be avoided. When once fixed to the wall
there is no necesity to remove them and the taking down and putting up of
the curtains is very easy which thus allows them to be readily shaken and cleaned.
Of course the apparatus may be made of all sizes and of any material.
Moreover for decorative purposes I may place the twisted rod in a split tube
thus covering it and hiding it from sight.
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:
In a novel arrangement of curtain rods, the combination of a smooth rod
mounted upon brackets and upon which the curtain rings are threaded with a
rod twisted in both directions upon which ride in opposite directions two nuts to
which the curtains are fastened by means of a screw, which rod rotates in two
brackets, and is provided at one end with a pinion over which passes a chain serving
to rotate the said twisted rod sometimes in one sometimes in the other direction
and by this means draw the curtains which follow the nuts in their travel to and fro
as desired.
