COMPLETE SPECIFICATION.
Improvements in Apparatus for Moving Curtains of Doors To
and Fro.
WILLIAM HOLBROOK of No. 46 Maple Road, Penge in the County of Surrey,
Cabinet Maker and Joiner 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 apparatus consists of boxes of metal, or other suitable material, springs and
levers.
In the rabete of the door, jamb, or post on which the door is hung is inserted a
box A-2 & 3 enclosed within said box is a bolt B Fig. 2 & 3 with mortice C through
it, the end of bolt projecting out when the door is open past the face of jamb. Also
in said box is a follower D see also detail Fig. 5 & 6 with the tongue or lever fixed
across and at right angles to the said bolt, the lever on said follower passes up through
the mortice in said bolt before described.
On the inner edge of the door jamb is fixed a box E Fig. 1, 2 & 3 with coiled
spring enclosed therein, also a spindle F. F 2 & 3 which passes through it into the
mortice in the follower before described, the one end of the spring being fixed to the
collar in the spindle and the other end made fast to the box, on the end of the spindle
projecting inside and past the box with coiled spring enclosed is fixed a long arm or
lever G. Fig. 4.
The top end of said lever is passed through the first or inner ring of the curtain,
when the door is closed the end of the bolt projecting past the face of the rebete in
door jamb comes in contact with the edge of the door causing it to go back and
forcing the long arm or lever which stood about perpendicular, at an angle across the
door taking the curtain with it, and holding it there till the door is opened, when the
spring enclosed in box and attached to the spindle before described causes the lever to
fly back drawing the curtain.
On the shutting or lock side of the door jamb is fixed a box with metal spring
enclosed, and spindle like the one on the other side before described, but to this
spindle and projecting through the said box and before the face of the door when
the door is open, is fixed a lever with a wheel or roller H. Fig. 7 & 8 on the end.
In the edge of the door and slanting downwards and projecting past the face of the
door is fixed a groove of metal I fig. 7 & 8, when the door is closed the wheel or roller
on the end of the lever before described passes down the said groove, causing the top
end of the long arm or lever to go to the centre of the door, and is held there till the
door is opened, when the wheel or roller passes up the groove, the lever or long arm

page_text: is then released, and goes back and stands about perpendicular, and the curtains hang
loosely down by the side of the door.
I wish it understood that I do not confine myself absolutely to the exact form
herein described and illustrated, obviously various modifications may be used without
departing from the spirit of the Invention, for instance, I may use a spring of a
different description such as a spiral, pulling upon the arms & Fig. 1 and always
tending to draw the curtains aside until forced together again upon the closing of the
door, may also utilize the movement of the door at some other portion, as for
instance nearer the floor transferring the motion obtained therefrom by means of rods
or chains in the like up to the positions shown on the drawing or in other ways too
obvious to require special additional description obtain the movement of the arms G
Fig. from the movement of the door.
Having now particularly described the nature of my said Invention and in what
manner the same is to be performed I declare that what I claim is
ist. The construction or arrangement and combination of these fittings for causing
the curtains to be drawn over or aside upon the door being opened or shut
substantially as described in reference to, and shown in the accompanying drawings.
2nd. The combination with one or more curtains of one or several arms or rods
capable of controlling the movements of the curtain or curtains and actuated directly
or indirectly by the door upon its being opened or shut substantially as and for the
purpose set forth.
In witness whereof I the said William Holbrook have hereunto set my hand and
seal this Third day of February One thousand eight hundred and ninety.
