PROVISIONAL SPECIFICATION.
An Automatic Rising Portiere Rod.
We BENJAMIN PERRY trading under the style or title of Perry & Phillips
Upholsterer Bridgnorth in the County of Salop and JAMES SYMONS, Auctioneer, and
Upholsterers Assistant, 4 High Street Bridgnorth in the County of Salop aforesaid
do hereby declare the nature of this invention to be as follows:-
The advantage claimed by this invention is that by the simple action of opening the
door the rod rises and lifts its curtain at least one inch when the door is opened to an
angle of forty five degrees and at least one and half inches when the door is fully
opened.
The action fixed to the architrave on the hinged side of door is a tube with
fixing. plate behind it. There is a spiral slot in the tube. The door rod is fixed'
horizontally to a short vertical shaft which fits into the tube and a screw or other
projection is inserted into the shaft at the bottom of the slot.
On the top rail of door near the opening edge a bracket is fixed with slot to hold the
rod and in the direction of the hinge on the underside of rod a wedge shaped piece is
attached tapering from nil to about 1 inches and long enough to cover the shortening
progress of the rod caused by the distance from architrave fixture to door hinge which
rises the rod on the opening side of the door exactly the same height as the spiral
motion on the hinged side thereof.
Dated this Fourth day of November 1889.

COMPLETE SPECIFICATION.
An Automatic Rising Portiere Rod.
We BENJAMIN PERRY, trading under the style or title of Perry & Phillips,
Upholsterer Bridgnorth in the County of Salop and JAMES SYMONS, Auctioneer and
Upholsterers' Assistant 4 High Street Bridgnorth in the County of Salop aforesaid
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:-
Our Invention has for its object An automatic rising portiere rod, the advantage
of which is, that, by the simple action of opening the door, the rod rises and gradually
lifts the curtain until when the door is quite open the curtain hangs clear off the floor
at the bottom by at least one & a half inches.
In order that our invention may be clearly understood and more easily carried into
practice we bave appended hereunto a double sized sheet of drawings upon which we
have fully illustrated the nature of our said invention.
Figure 1, is an elevation of part of a door B and architrave D.having one of our
portiere rods A attached thereto.
Figure 2, is a side elevation of the door attachment E.
Figure 3 is a similar elevation to Figure 1 but shewing a slight modification in the
door attachment E¹.
Figure 4, is a side elevation of the door attachment E¹.
Figure 5, is a side elevation of the attachment F to the architrave D.
Figure 6, shews an elevation of a portiere rod in which one end only of the rod A
is made to rise.
Figure 7, is an enlarged front view of the action F for attachment to the architrave
in the case of Figures 1 and 3 shewn as when the door is closed.

page_text: Figure 8 is a similar view to Figure 7 but shewing the action Fras when the door
is open.
In carrying our invention into effect we fix the tube F to the architrave D on the
hinge side of the door A by means of the fixing plate f¹ to which the tube F is
attached. This tube F is provided with the spiral or diagonal slot or groove f² and
receives the vertical shaft A' which fits and turns in the said tube F and when the
shaft A¹ is down in the position shewn in Figure 7 the screw.H or other projection is
inserted into the shaft so that, as the shaft A' is turned the projection H travels up the
slot thereby raising the shaft. A to the position shewn by Figure 8.
On or near the top rail of the door B at the opening edge the bracket E is fixed.
and is either provided, with the fork e² to receive the rod A as shewn in Figure 1 or
is pivotted to the rod :A.as shewn in Figure 2 the wedge shape piece in the case of
Figure 1 being fixed to the underside of the rod A which has a similar amount of
taper to the amount of rise in the shaft A¹ and is sufficiently long to allow of the
shortening of the distance between the bracket E and the attachment F so that as the
door opens the rod A is lifted at that end to a similar extent to the other end.
In the case of the bracket El as seen in Figures 3 & 4 the one end of the bracket E'
is fixed by the pivot plate e to the rail of the door the other end of the bracket E'
being, pivotted at 4 to the rod A so that as the distance between the pivot and
action F is shortened by the opening of the door, the rod A is caused to rise at the
opening side, the same amount as at the hinge side.
1.
We may cause the rod A to rise only at the opening side as shewn at Figure 6 in
which, case the other end would turn on the plain pivot K, sufficient freedom being
left in the socket on the rod to allow the said rod to take the position shewn by the'
dotted lines in Figure 6, when the door is opened and as the curtain requires to be
lifted most on the opening side this in many cases may be sufficient while the same
object can be obtained by the wedge shaped piece before described.
Adjustment in the amount of rise and fall of the rod may be obtained on the hinge
side by altering the position of the screw H and on the opening side by altering the
position of the pivot e' upon the rod for which purpose the screws are provided.
The rod may of course be fixed at any desired height to suit varied conditions.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed we declare that what
we claim is
1st. An automatic rising portiere rod in which the rod is automatically raised and.
lowered substantially such as herein set forth and illustrated upon the accompanying
drawings.
2nd. The improvement in curtain rods consisting of the spiral or diagonal slot or
groove f in the tube F substantially as and for the purpose herein set forth and
shewn upon the drawing.
