PROVISIONAL SPECIFICATION.
Improvements in connection with Door Curtains.
I, FREDERICK HENRY YOUNG of 73 Saint Pauls Road Moseley Road
Birmingham in the County of Warwick do hereby declare the nature of this
invention to be as follows:-
This invention has for its object the production of a portiere rod which will in
addition to the usual advantages connected with the use of a portiere rod, be so
constructed that the opening of the door will lift or raise the curtain.
By the first modification of my invention I form my portiere rod out of metal tube,
wood, or other suitable material, the rod being hinged so as to form a short arm
near the door jamb and a long arm the width of the door, so far I have described
an ordinary portiere rod and so far I do not claim any novelty, the novel parts
constitutiting my invention are hereinafter described.
Instead of providing a joint formed of flanges or sections revolving over a central
axial pin on horizontal planes, I form my hinge or joint out of two or more
portions revolving over a central axial pin on angular planes, or what is techni-
cally termed a rising joint; the axial pin of the rising joint will project from the
bottom of joint cheeks to any suitable distance, and on this projecting shank will
be placed a spiral spring, and beyond the spiral spring will project a knob or
flange to retain the spring in position ready for use.
As a further development of my invention I modify the form of the door bracket
usually used near the edge of door by forming such bracket with a bearing guide
and central shieve; I next provide a rod bracket formed with a socket and
adjusting screw the socket being of suitable internal diameter to pass on to and
slide along the portiere rod, the adjusting screw would take into the upper face of
socket and from the lower face would project a straight or curved guide rod the
axis of the straight guide rod being situated at an angle of thirty degrees with the
axis of the portiere rod or at any other suitable angle.
The guide rod would be passed through the bearing guide of door bracket and
would take a bearing in the shieve.
The action of my rising portiere rod would be as follows:-
By opening the door, the upper part of rising hinge would rotate round its axial
pin, pressing against the inclined plane formed on the half of hinge secured to
short arm of portiere rod the hinge in rising up the inclined plane would lift the
axial pin and compress the spiral spring placed over the projecting end of axial pin,
thus lifting that edge of door curtain suspended near the rising hinge at the same
time the edge of the door in describing a large circle from the axis of rising hinge
joint would press the door bracket shieve against the guide rod of rod bracket and
as the portiere rod bracket would be connected tightly to the portiere rod by means
of the adjusting screw the end of the portiere rod would be raised by the action of
the guide rod against the shieve, thus the curtain would be lifted clear of the floor.
The essential part of the first modification of my invention therefore consists in
the utilization of a rising joint and the utilization of a shieve and bearing guide on
a portiere rod door bracket in conjunction with the guide rod of a portiere rod
bracket as and for the purpose described.
The second modification of my invention has for its object the production of a
portiere rod that will rise by the opening of the door such portiere rod being in
one length instead of being hinged near the door jamb as described in the first
nodification.
I form the second modification of my portiere rod out of metal tube, wood, or
other suitable material the rod being in one piece,

page_text: I utilize a door bracket on which is provided a bearing-guide and central shieve
together with the socketed rod bracket as described in the first modification of
my invention and by the utilization of such door bracket and rod bracket lift
the front end of the portiere rod in the manner described in the first modifica-
tion but the back end of the portiere rod is raised in the manner hereinafter
set forth.
I provide a spindle bearing bracket which consists of a bracket projecting at
a suitable angle from the door jamb the spindle bearing bracket may be formed
out of wood, cast metal, stamped metal or other suitable material and would be
provided with suitable flanges or cars by means of which the bracket can be
screwel or otherwise secured to the door jamb, the spindle bearing bracket is
pierced horizontally with a spindle hole.
I next provide a rising-spindle; the shank of the rising spindle is passed into
the spindle hole provided in spindle bearing bracket and the head of the spindle
is connected to the back end of the portiere rod by any suitable mechanical
means; it will thus be apparent that when a portiere rod is so connected to a
door and door jamb the opening of the door would cause the portiere rod to
move the rising spindle in the spindle bearing bracket the spindle and bracket
would thus form the axis on which the portiere rod moved.
The back end of the portiere rod is raised or lifted to correspond with the
lifting of the front end by the action of the parallel motion or series of connecting
rods hereinafter described.
I provide a top link or rod of suitable length and dimensions and pivot one end
of such link to the head of rising spindle.
I provide an opening in the spindle bearing bracket and place therein a nut or
collar the shank of spindle passing through such nut or collar.
1 provide a bottom link and pivot one end of such bottom link onto the nut
or collar and the other end of bottom link I pivot to the top link at about the
centre of the length thereof.
On the door bracket I provide a suitable connecting rod boss which may be
solid or which may be slotted I next provide a connecting rod of a suitable
length and pivot one end to the connecting rod boss provided on door bracket
and then pivot the other end of connecting rod to the bottom end of top link.
The parallel motion would actuate or lift the rising spindle in the following
manner :- -The opening of the door would cause the door bracket to push back
the connecting rod; the back end of the connecting rod would press against
the bottom end of top link the centre of top link being attached to the end of
bottom link would raise the bottom link and the top end of top link pivoted to
the head of spindle would press against such head and thereby lift the head and
consequently raise the shank out of the spindle bearing bracket thus lifting the
back of the portiere rod at the same time that the front of such rod was being
raised by the action of the rod bracket and rod, over the shieve provided on door
bracket.
By a third modification of my invention I dispense with the parallel motion with
its connecting rod, two links, and nut or collar.
I provide a spindle bearing bracket very similar in external appearance to
the spindle bearing bracket of second modification through such spindle bearing
bracket is pierced a passage and this passage is in the form of a female screw
of suitable pitch; I next provide a rising spindle very similar to the rising
spindle described in second modification the exception being that whereas the
spindle of second modification is a plain cylinder the spindle of third modification
has formed thereon a male screw thread of suitable pitch to connect with the
female screw thread formed in the spindle bearing bracket.
The action of this third modification is as follows:-
The opening of the door would cause the shank of spindle to revolve within
the bearing bracket such revolution of the spindle would press the thread formed
on shank of spindle against the corresponding inclined plane or female thread

page_text: formed in spindle bearing and such action would cause the spindle to rise and
thus lift the back end of portiere rod.

COMPLETE SPECIFICATION.
Improvements in connection with Door Curtains.
I, FREDERICK HENRY YOUNG of 73 Saint Pauls Road Moseley Road,
Birmingham in the County of Warwick do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
This invention has for its object the production of a portiere rod which will in
addition to the usual advantages, connected with the use of a portiere rod, be so
constructed that the opening of the door will lift or raise the curtain.
By the first modification of my invention I form my portiere rod out of metal
tube, wood, or other suitable material, the rod being hinged so as to form a short
arm near the door jamb and a long arm the width of the door, so far I have
described an ordinary portiere rod and so far I do not claim any novelty, the novel
parts constituting my invention are hereinafter described.
Instead of providing a joint formed of flanges or sections revolving over a central
axial pin on horizontal planes, I form my hinge or joint out of two or more portions
revolving over a central axial pin on angular planes, or what is technically termed a
rising joint; the axial pin of the rising joint will project from the bottom of joint
cheeks to any suitable distance, and on this projecting shank will be placed a spiral
spring, and beyond the spiral spring will project a knob or flange to retain the
spring in position ready for use.
As a further developement of my invention I modify the form of the door
bracket usually used near the edge of door, by forming such bracket with a bearing
guide and central shieve; I next provide a rod bracket formed with a socket and
adjusting screw the socket being of suitable internal diameter to pass on to and
slide along the portiere rod, the adjusting screw would take into the upper face of
socket and from the lower face would project a straight or curved guide rod
the axis of the straight-guide rod being situated at an angle of 30 degrees with the
axis of the portiere rod or at any other suitable angle.
The guide rod would be passed through the bearing guide of door bracket and
would take a bearing in the shieve.
The action of my rising portiere rod would be as follows:-
By opening the door the upper part of rising hinge would rotate round its axial
pin, pressing against the inclined plane formed on the half of hinge secured to
short arm of portiere rod, the hinge in rising up the inclined plane would lift the
axial pin, compress the spiral spring placed over the projecting end of axial pin,
thus lifting that edge of door curtain suspended near the rising hinge, at the same
time the edge of the door in describing a large circle from the axis of rising
hinge joint would press the door bracket shieve against the guide rod of rod bracket
and as the portiere rod bracket would be connected tightly to the portiere rod by
means of the adjusting screw the end of the portiere rod would be raised by the
action of the guide rod against the shieve, thus the curtain would be lifted clear of
the floor.
The essential part of the first modification of my invention therefore consists in
the utilization of a rising joint and the utilization of a shieve and bearing guide on
a portiere rod door bracket in conjunction with the guide rod of portiere rod
bracket as and for the purpose described.

page_text: The second modification of my invention I abandon.
By a third modification I provide a spindle bearing bracket, through such spindle
bearing bracket is pierced a passage and this passage is in the form of a female
screw of suitable pitch; I next provide a rising spindle; the rising spindle of third
modification has formed thereon a male screw thread of suitable pitch to connect
with a female screw thread formed in the spindle bearing bracket.
The action of this third modification is as follows:-
The opening of the door would cause the shank of spindle to revolve in or on
the bearing bracket such revolution of the spindle would press the thread formed
on shank of spindle against the corresponding inclined plane of female thread
formed in spindle bearing and such action would cause the spindle to rise and thus
lift the back end of portiere rod.
The nature, characteristics, features, and scope of my invention, having been set
forth under three modifications in my Provisional Specification, I abandon the
second modification and will now proceed to describe the first and third modifications
with reference to the accompanying drawings, similar letters refer to similar parts
throughout the several views.

of the rising joint Figure 11.
Figure 13, 14, 15, 16, and 17 represent various views of the method of rising
described in third modification of Provisional Specification.
In carrying out my invention I provide a portiere rod 1 which may be made out
of metal tube, wood, or other suitable material, such rod being hinged so as to form
a short arm 2 near the door jamb.
3
Instead of providing a joint of the usual kind, I form my hinge or joint out of
two or more portions 3 and 4 revolving over a central axial pin 5 on angular 4
planes 6, in the following manner :-
5 represents the axial pin, 3 represents the lower half or portion of rising joint,
4 represents the upper half or portion of rising joint, the upper portion 4 is pierced
with an opening as shewn in detail at 7 Figure 8, such jaw opening passing over
the central axial pin after such axial pin has been passed through the central 4
hole 9, and revolving a portion of a circle over such axial pin, the
jaw portion of the joint being suspended on the linch pin 10 as shewn in detail at
half or
upper
Figures 4 and 5; the angular planes 6 are in some cases provided as shown in plan
detail Figure 12, forming a spheriodal rose head which moves on the angular,
concave, spheriodal, surface 11 formed in the lower half or portion 3 of rising joint 50
provided to receive it, the angular planes or faces formed on the upper half of
rising joint leaving spaces for a film of oil between the rose head and its cup
bearing, the action of the complete rising joint hereinbefore described permitting
the front end of the portiere rod to be raised by the action of the door bracket 12
as hereinafter described.
As a further developement of my invention I modify the form of the door
bracket usually used near the edge of door by forming such bracket with a bearing
55

page_text: guide 13 and central shieve 14, or two or more shieves 15 16. I next provide a
rod bracket 17 formed with a socket, and with an adjusting screw 18, the socket
being of suitable internal diameter to pass on to and slide along the portiere rod 1,
the adjusting Ecrew would take into the upper face of socket and from the lower
face would project a straight or curved guide rod 19, the axis of the straight-guide-
rod being situated at an angle of 30 degrees with the axis of the portiere rod or at
any other suitable angle.
The guide rod 19 would be passed through the bearing guide 13 of door bracket
and would take a bearing in the shieve 14 or on the pair of shieves 15 16. The
action of my rising portiere rod would be as follows:-
By the opening of the door the upper part 4 of rising hinge would rotate
round the axial pin 5 pressing against the inclined surface formed on the half of
hinge secured to short arm 2 of portiere rod, the hinge in rising up the inclined
concave plane 11 would in conjunction with the rising action of the front guide
rod 19 tend to lift the axial pin 5 and compress the spiral spring 20 placed over the
projecting end 31 of axial pin, thus slightly lifting or easing that edge of door
curtain suspended near the rising hinge, at the same time the travelling edge of
door in describing a large circle from the axis 5 of rising hinge joint would press
the door bracket shieve 14 or shieves 15 16 against the guide rod 19 of rod
bracket 17, and as the portiere rod bracket 17 would be connected tightly to the
portiere rod by means of the adjusting screw 18 the front end of the portiere rod
would be raised by the action of the guide rod 19 against the shieve 14, or
equivalent shieves 15 16, thus lifting the curtain clear of the floor.
By a third modification I provide a spindle bearing bracket 21 through such
spindle bearing bracket is pierced a passage 22 and this passage is in the form of a
female screw 23 of suitable pitch; I next provide a rising spindle 24 on which is
formed a male screw thread 25 of any suitable pitch to connect with the female
screw thread 23 formed in the spindle bearing bracket.
As an equivalent to the male thread 25 I may in some cases form an helical
groove 26 on the outward periphery of the rising spindle as shown at Figure 14
and it will be readily understood that the helical groove 26 would when revolving,
work over the end of pin 27 as a mechanical equivalent to the action of the male
thread 25 as hereinbefore described.
When the portiere rod is in one length as described in third modifications, the
curtain can (if required) be lifted at the back to the same height that it is lifted at
the front, in contradistinction to the first modification, where the rising at the hinge
joint to any considerable height would disarrange the curtain on the short arm that
does not lift.
The action of the third modification is as follows:-
The opening of the door would cause the shank of spindle to revolve within the
bearing bracket 21 such revolution of the spindle would press the thread 25 or 28
formed on the shank of spindle against the corresponding inclined plane of female
thread formed in spindle bearing bracket and such action would cause the spindle
to rise in its socket thus lifting the back end 29 of portiere rod connected to head
of spindle; in a like manner conversely, the helical groove 26 would revolve over
the pin shank 27 as illustrated at Figure 14, thus lifting the spindle.
The opening of the door would in a like manner cause the female threads formed
in the hollow shank of spindle to revolve over the male threads 30 formed on the
upper part of bearing bracket as illustrated at Figure 13.
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,
1st. The combination with a door curtain rod of mechanism for lifting the front
end of such door curtain rod, such mechanism consisting of a rod bracket secured
to the door curtain rod, the rod of such rod-bracket working against a shieve or
shieves provided in or on a bearing guide, such bearing guide being connected to a

page_text: door bracket fixed to a door, so that by opening the door the bearing guide of door
bracket will continually press the shieve or shieves against the rod part of guide
rod, thereby moving the rod bracket in an upward direction, thus lifting the front
end of the door curtain rod together with the door curtain hung thereto, as
illustrated and described.
2nd. The combination with the apparatus hereinbefore claimed of the rising
hinge joint mechanism as illustrated and described in reference to the axial pin
the bottom half 3, the top half 4, the spiral spring 2 and the linch pin 10, as and
for the purpose described.
3rd. The combination with a door curtain rod (not hinged) of mechanism for
lifting the back end of such rod:-consisting of a spindle bearing bracket and
rising spindle, the rising spindle being provided with a male screw thread taking
into a female screw thread formed in the bracket, as illustrated and described in
reference to Figures 15 and 16 as and for the purpose described.
4th. The combination with the door curtain rod (not hinged) of mechanism for
lifting the back end of such rod :-consisting of a spindle bearing bracket and
rising spindle, the rising spindle being provided with an helical groove taking on to
a set pin, as illustrated and described in reference to Figures 14 and 17, as and for
the purpose described.
5th. The combination with a door curtain rod (not hinged) of mechanism for
lifting the back end of such rod:-consisting of a spindle bearing bracket and
rising spindle, the rising spindle being provided with a socket and female thread
taking on to a male thread formed on the upper spindle end of door curtain bracket,
as illustrated and described in reference to Figure 13-as and for the purpose
described.
