Improvements in the Construction of Curtain Poles and the like.
"
GERSHON BOWMAR, 355, Earlsfield Road, London, S.W., do hereby declare
the nature of this invention to be as follows:-
The object of this invention is to construct curtain poles that the curtain or
material suspended moves and its folds open evenly and automatically as and
when the end is moved.
To attain this I propose to have the poles, cane wood or other substitute made
or be made, hollow, and a slot. Inside the pole I provide for a spiral spring or
substitute to be placed at one or both ends or centre. On this spring I have
hangers at any desired distance apart one end of the spring is fixed the other
end has a loop to which a cord is attached for drawing the spring to any length
the spring opens evenly and thereby the folds of the material. The cords may
run through the length of the pole and have rollers to prevent chafing of cord in
a convenient place and fasteners on their ends or other convenient place for
fastening the cord at any desired length. I may have the spring or substitute
of large diameter and the poles inside, thus solid poles the moving of the spring
and material would be similar to before mentioned.
In the curtain pole I may have the spring fixed in a detachable socket and in
this socket a wheel or roller.

Improvements in the Construction of Curtain Poles and the like.
I, GERSHON BOWMAR, formerly of 355, Earlsfield Road, but now of 371, Earls-
field Road, Earlsfield, in the County of Surrey, 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:-
This invention relates to curtain poles and the like, and is designed to provide
a simple and an effective device whereby curtains, blinds or other like articles
may be moved along their poles or other supports in such a manner that the
supporting points shall always be evenly distributed along the pole or support
whatever be the extent to which the curtain or the like is extended or drawn out
or folded or pushed back; that is to say, that each of the folds of the curtain shall
open or close evenly or to a substantially equal extent.
According to my invention I employ a spring or springs provided or formed
with hangers, rings or other means for enabling the curtain, blind or the like to

page_text: be attached thereto; the said spring or springs being arranged within or about
the pole with one or their ends secured to the said pole and the other to a cord
by means of which, when the curtain is to be drawn, the said springs can be
extended and maintained in their extended position. Un releasing saiu cord the
springs will contract and so automatically draw back the curtain to its folded
or unextended position.
In order that my invention may be clearly understood and readily carried
into effect I will describe the same more fully with reference to the accompanying
drawings.
Figure 1 is a fragmentary view partly in section shewing the two ends of a
curtain pole constructed in accordance with my invention.
Figure 2 is a transverse section on the line A, B of Figure 1.
Figure 3 is an elevation of a modification of my improved device, in which
the springs surround the pole instead of being arranged within the same.
Referring first more particularly to Figure 1, a is a hollow pole having a longi-
tudinal slot or opening b. The ends of the pole constitute plugs c and are
secured to the body of the pole by a bayonet or other suitable joint or device
which will permit of the said ends being detached. Inside the pole and adjacent
to each end thereof, I provide a series of any desired number of springs d, d, à,
each spring being connected with the other by a plate or strip of metal e so
bent as to constitute a hanger which projects through the longitudinal slot in
the pole, and to which the curtain, blind or the like is attached, either directly as
shewn at the left hand side of Figure 1; or by means of the ordinary curtain
ring which is soldered or otherwise secured to the strip e and which receives a
book or loop secured to the curtain in the ordinary manner, as shown at the
right hand side of Figure 1.
To the free end of each series of springs is attached a cord or chain which
passes over a suitable pulley or roller h upon the opposite end of the pole, and
thence through the longitudinal slot or opening b.
The operation of my improved device is as follows:-The pole being in
position, the curtain, blind or the like is attached to the strips or hangers e and
the springs will maintain the curtains in equidistant and practically even folds
near each end of the pole. When it is desired to extend one of the curtains along
the pole, the respective cord g is pulled and the springs are thereby extended,
carrying with them the strips e to which the curtain is attached. When the
curtain has been moved the required distance, the cord is fastened in any suitable
manner to the window-frame, wall or other convenient part. Upon releasing
the cord the springs return to their normal position carrying with them the
curtain or blind.
The detachability of the ends of the pole renders it quite easy to remove,
repair or replace the springs, cords or other parts.
Instead of arranging the springs within the pole, I may arrange them outside
the same in which case the pole may be solid. Figure 3 illustrates such a con-
struction, wherein the springs d, d surround the pole; each series of springs
being attached at one extremity to the end of the pole and at the other extremity
to a cord g, and also having hangers ee for the attachment of the curtain or
blind, in the same manner as described with reference to Figure 1. Smaller
springs may however be employed arranged beneath or on each side of the pole
instead of around the same.
If desired the aforesaid springs may be so arranged that they normally
iend to keep the curtain extended or closed, and then it would be necessary to pull
the cords to open the curtain.
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: -
1. A curtain pole or similar device provided with a spring or springs to which
the curtain is attached for the purpose specified.

page_text: 2. A curtain pole having its parts constructed and arranged to operate sub-
stantially as described with reference to the accompanying drawings for the
purpose specified.
