Improvements in Extending Poles or Self Adjusting Curtain Rods.
ARTHUR ERNEST WALKER Manufacturer 18 Chiswell Street London E.C.
do hereby declare the nature of this invention to be as follows :--
This invention is a simple means of providing a rod capable of extension to
admit of its fixture in fire places & stoves so as to form a novel curtain fire screen
or fire place decoration.
A is a rod to which is fixed a swivelled ornamental barrel capable of turning on
its own axis.
B is a cap fitted on rod A with a groove D in it over which the collar E of
barrel just fits, the pin P is then driven in & so fixing the collar & at same time
allowing it to revolve.
In the rod a hole is bored to admit the small spindle S. This spindle is notched
or cogged at bottom or has a longitudinal section piece of a screw fitted to it.
The mouth of barrel G has a hole screwed also with a female screw as shown
at M which fits the thread of the screw fixed or fitted to the spindle S-when
therefore the barrel is turned by the hand the spindle is propelled at end. A
pin P¹ may also be made long enough to enter the groove D & also the slot in the
spindle S so as to fix it & prevent its movement other than forward or backward.
The cap B is not absolutely necessary as the rod may be turned itself to answer
the same purpose as the cap B.
The spindle S may also be maintained firmly in its position by a groove in rod A
as seen in Fig. 21, the innermost hole being bored in rod A to receive the rod S
as B Fig. 3.
Fig. 2 shows the same method, but the action is reversed, i.e., the notch K acts
upon the screwed spindle S propelling or withdrawing it when the barrel B is
revolved. The barrel B being itself grooved at G & the pin P being driven
through the outer rod A & 50 fixing it from going backward or forward but
allowing it to have a revolving motion nevertheless.
Any of these motions may be reversed, i.e., the inner or outer rods may revolve
as the principle is the same, rod S may revolve outside & around rod A. and so on.
Fig. 4 T shows another mode of working viz., the inner rods are propelled or
withdrawn either end at the same time by means of a double screw as Fig. 4 U,
connected by coggs to an endless screw or cogged wheel, which is worked on
turning the thumb screw as Fig. 4. T.

COMPLETE
SPECIFICATION.
Improvements in Extending Poles or Self Adjusting Curtain Rods.
ARTHUR ERNEST WALKER Manufacturer 18 Chiswell Street London E.C.
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 is a simple means of providing a rod capable of extension to
admit of its fixture in fire places & stoves so as to form a novel curtain fire screen
or fire place decoration, or for the use of window blinds & curtains.
The drawing furnished with the Provisional Specification shows various modes

page_text: of working the extending rods, viz., A Figs. 1 & 2' is a rod to which is fixed a
swivelled ornamental barrel capable of turning on its own axis. B is a cap fitted
on rod A, Fig. 1 with a groove D in it, over which the collar E of barrel just fits.
A pin P is then driven through it, just far enough to catch in the groove so as to
fix the collar at that point from moving backwards & forwards, yet allowing it to
revolve see Fig. 2 P.
In the rod A'Fig. 1 a hole is bored to admit the small spindle S. This spindle
is notched or cogged at bottom or has a longitudinal section piece of a screw
fitted to it.
The mouth of barrel G has a hole screwed also with a female screw as shown
at M Fig. 1 which fits the thread of the screw fixed or fitted to the spindle S
Fig. 1 when therefore the barrel is turned by the hand at end it propels the
spindle S.
The cap B is not absolutely necessary as the rod may be turned itself to answer
the same purpose as the cap B.
The spindle S may also be maintained firmly in its position by a slot run longi-
tudinally in the hole bored in A to receive it as shown in Fig. 3.
Fig. 2 shows the same method but the action is reversed, i.e., the notch, K acts
upon the screwed spindle S, propelling or withdrawing it when the barrel B is
revolved.
The barrel B being itself grooved at G & the pin P being driven through the
outer rod A and so fixing it from going backward or forward, but allowing it to
have a revolving motion nevertheless.
Any of these motions may be reversed, i.e., the inner or outer rods may revolve,
as the principle is the same-rod S may revolve outside rod A and so on.
Figs. 4 & 5 show another mode of working as follows, the rods are substantially
as heretofore described but made to propel at each end-by means of a double
reversed screw coggs W fixed on the rod S as at Fig. 5-serving to turn the
inner rod by. means of a small wheel on edge of which is a worm or endless
screw as shown at R Fig. 5, and attached to thumb screw as shown at X Fig. 5.
Again the rod A as shown at Fig. 6, may be quite plain, of tubular form,
allowing the inner tubular rods, which are nearly the same length as the outer
rod, to be extended or propelled by means of a milled edge thumb piece, in the
shape of a nut, placed at B, as in Fig. 6. This nut when turned with thumb
& finger (a place being cut in the tube to admit of them) carries with it screw
rod S, which passing through the next adjacent orifice of the outer propelling
ends, & which orifices are fitted with a female screw, allows of their forward
movement. The two washers C and C¹, keep the screw S in position, or they
may be dispensed with, see dotted lines Fig. 6.
Having now particularly described & 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 the following features of novelty.
1. A tube or pole in metal or wood, capable of extending & maintaining
sufficient grip when placed between two jambs or posts to allow the said rod or
pole to bear a fair weight without giving way, but which can be removed auto-
matically & without fixtures.
2. A self adjusting curtain pole or blind rod.
