PROVISIONAL SPECIFICATION.
Improvements in and connected with Door and other Curtain Rods.
I, PHILIP LEWIS of Golden Hillock Road Birmingham in the County of
Warwick Machinist, do hereby declare the nature of this invention to be as
follows
-
This invention has reference to improvements in the construction of that descrip-
tion of curtain rod which is attached to doors and similar situations and so arranged
that the action of opening the door raises the curtain and prevents it dragging upon
the floor.
This I effect in the following manner :-To the door casing or jamb I attach_a
plate of metal having attached to it by a knuckle or other suitable joint an arm. To
the other end of this arm is pivotted a toothed bar or rack held within a casing
which is attached to the door so that the action of opening and closing the door
causes this toothed rack to slide backwards and forwards. The curtain rod is
carried by two arms one end of each being pivotted to the rod and the other end
pivotted to a projecting piece or pin attached to the door. Upon the projecting
piece or pin nearest the hinged side of the door is also placed a quadrant or fan-
shaped toothed pinion its teeth taking into the teeth of the above mentioned rack
so that opening the door causes the toothed rack to travel and turn the fan-shaped
pinion a portion of a revolution and thus raising the arms and the rod which they
carry lifts the curtain off the floor. By extending the arm carrying the toothed
bar so as to enable me to repeat the rack and toothed pinion arrangement but
reversing the action of this one I am enabled to construct the curtain rod with a
telescopic action thereby drawing the curtain back as well as raising it in the action
of opening the door.

COMPLETE SPECIFICATION.
Improvements in and connected with Door and other Curtain Rods.
I PHILIP LEWIS of Golden Hillock Road Birmingham Machinist 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,
reference being had to the accompanying drawings and to the letters and figures
marked thereon:-
This invention has reference to improvements in connection with that description
of curtain rods which are attached to doors and similar situations and are so arranged
that the action of opening the door raises the curtain and prevents it dragging upon
the floor.
This I effect in the following manner :- To the door casing or jamb I attach a
plate of metal having an arm attached to it by a knuckle or other suitably.
formed joint to the other end of this arm is pivotted a toothed bar or rack
held within a casing which is attached to the door so that the action of
opening and closing the door causes this toothed rack to slide backwards and
forwards. The curtain rod is carried by two arms one end of each being pivotted
to the rod and the other end pivotted to a projecting piece or pin attached to the
door. Upon the projecting piece or pin nearest the hinged side of the door is also

page_text: placed a quadrant fan shaped toothed pinion with its teeth taking into the teeth of
the above mentioned rack so that opening the door causes the toothed rack to travel
and turn the fan shaped pinion a portion of a revolution and thus raising the arms
and tlie rod carried by them lifts tlie curtain off the floor. By extending the arm
carrying the toothed bar so as to enable me to repeat. the rack and toothed pinion
arrangement but reversing the action of this second one I am enabled to construct
the curtain rod with a telescopic action thereby drawing the curtain Back as well as
raising it in the action of opening the door.
Referring to the drawings.
Fig. 1 illustrates the position of the various parts when the door is closed and
Fig. 2 their position when the door is open.
(A) is a metal plate attached to the door casing (B) is an arm connected to the
plate (A) by the knuckle joint C at one end and pivotted at the other end (D) to
the toothed bar or rack (E) which slides in the casing (F) upon the plate (G)
which plate is attached to the door. Opening the door will then cause the
rack (E) to travel forward and as the teeth of the rack (E) work into the teeth of
the fan shaped pinion (H) the pinion (H) will be moved into the position shown in
Fig. 2. The arms (I J) are pivotted at one end to the plate (G) and at the other
end to the rod (K) the arm (1) being attached to the pinion (H) moves with it and
is thus raised together with the other arm (J) and the rod (KK) into the position
shewn in Fig 2 and lifts the curtain which would be hung upon the rod K.
Fig. 3 is a modification of the invention in which modification I dispense with the
rack (E) and pinion (H) and substitute the plain sliding bar (L) working in the
guide piece (M) and having the pin (N) working in the slotted arm (0) so that
the opening of the door throws the bar forward and raises the arms carrying the rod
as shown in Fig. 4.
Fig.
and 6 illustrate the arrangement for a telescopic curtain rod. (G') is a
sliding bar or plate carrying the toothed rack (E) and a second toothed rack (E¹)
and (H) is a second pinion. These being arranged to work the reverse way to the
rack and pinion (E and H) cause the arms (I and J) to be thrown in opposite
directions and the rod (K) being formed in two parts (K K¹) telescoping into one
another the action of opening the door will not only raise the arms (1 and J) but
will contract the length of the telescopic rod (K) and cause the curtain hung
thercon to be folded so as not to project beyond the door when open.
The telescopic rod may if desired be used with any of the other arrangements
named for raising the curtain off the floor, or with modifications thereof.
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. The improvements in and connected with door and other curtain rods
consisting of the knuckle joint (C) or other similar joint attached to the door jamb
or frame and in connection with the arms, rod, and other parts substantially as
described and for the purpose named.
2. The telescopic rod in combination with the other parts substantially as
described for the purpose of contracting the curtain when the door is opened.
