Improvement in the Construction of the Joints of Curtain Arms
of Bedsteads.
ARTHUR HAWLEY ASSINDER, Empire Works, Heath Mill Lane, Birmingham,
Bedstead Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The bottom bracket which is attached to the pillar of bedstead and supports the
arm is provided with three slots connected with each other by conical surfaces.
The plug at the bottom of standard of the curtain arm is fitted with a peg which
when the arm is moved passes from one of the slots to the other and remains
fixed in either slot as desired. The breakage of the bracket by moving the arm
thus becomes impossible.

Improvements in the Construction of the Joints of Curtain Arms
of Bedsteads.
I, ARTHUR HAWLEY ASSINDER, of Empire Works, Heath Mill Lane, Birmingham,
Bedstead Manufacturer, 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 relates to the joints of curtain arms for bedsteads, and has for
its object, to provide means for retaining the curtain arm in either one of three or
other number of desired positions without the employment of locking devices
requiring to be independently operated or released.
According to my invention the releasing of the arm is effected automatically on
the same being swung round upon its joint and it is likewise self-retained in a set
position by the movable part falling by gravity and connecting itself with the
other and fixed part.
My said invention comprises a curtain arm having a standard, the upper and
lower ends of which rotate and rise and fall within eyes made through suitably
disposed outstanding brackets supported by the pillar of a bedstead, with the
topside edge of the lower bracket, contiguous to the eye, being formed with
keeping gaps, two of which are arranged opposite to one another and the third
in an intermediate position between the said middle gap being connected to the
outer gaps by two pairs of inclined planes or races, with the said outer gaps each

page_text: terminating on one side, in stop shoulder. The difference in height between the
summit and the base of these double inclined rises or swells is equal to the vertical
movement capable of being made by the rising and falling standard, the lower
end of which carries a peg which runs or traverses over the said inclined-sided
rises when the curtain arm is pulled or swung round, either directly or through
the medium of the curtain, whilst normally, the peg takes in one or other of the
separated keep gaps or seatings and retains the curtain arm in one of three
positions, folded over across the bed, or in its position of use in the longer
direction of the bed, or right away from the bed.
Figure 1 of the accompanying drawings represents a side elevation of the curtain
arm of a bedstead, fitted with a joint constructed according to this form of my.
invention.
Figure 2 is a front elevation of the same. The curtain arm, in these two views,
is shown in its position of use, with the peg on the standard lying within the
middle retaining gap of the lower bracket.
Figure 3 is an elevation, upon an enlarged scale, of the joint part of the curtain
arm separately, with the stud on the standard lying in the near side gap of the
eyed bracket thus retaining the curtain arm in a right angled. position relative to
the bedstead.
Figure 4 is a like view as Figure 3, but showing the peg in the act of passing
from the one gap to the other on the standard being turned, by the swinging
round of the arm.
Figure 5 is a front elevation of the said joint, showing the peg lying in the
middle gap of the bracket so as to retain the curtain arm in line with the longer
direction of the bed.
Figure 6 is a horizontal section of Figure 3, upon the dotted line, showing the
bracket and peg in plan.
Figure 7 is a like section of Figure 5 upon the dotted line x¹.
Figure 8 is an elevation of the lower or plug end of the standard..
Figure 9 is a cross section of Figure 8 upon the dotted line 2, and Figure 10
shows the headed screw whereby the standard is connected with the bracket.
Figure 11 is an edge view and Figure 12 a front elevation of the bracket
separately.
Figure 13 is a section thereof upon the dotted line ³, Figure 12.
Carried by the pillar a, of a bedstead, are a pair of separated brackets a', a²,
having central eyes a³, a³, wherein the upper and lower pivot ends 61, 62, of a
vertical standard 63, carrying the curtain arm b', take and are capable of rotating
and rising and falling therein. Carried by the lower end 63, of the standard,
is a stud or pin c, which is capable of turning with the standard but normally
lies in one or other of a series of three separated gaps a, a, a7, with the gaps as, a²,
lying opposite to one another, whilst the intermediate of middle gap a, is separated
from the others by a pair of double-inclined rises, a8, a³ with the distance between
the apex of each rise and the bottom of each gap being equal to the rising move-
ment which the standard and arm make when the said arm is swung round, which
compels the peg to rise up the incline on one side of the swell, carrying the
standard and arm with it, and then descend by gravity or momentum the other
incline and run into the gap. The three definite positions in either of which the
arm is retained by the self-finding joint are determined by the peg falling into
one or other of the separated keep gaps. The curtain arm is prevented from
moving beyond its inward or outward right angled positions by stop
shoulders a0, a1, at the terminations of the side gaps as, a².
Figure 14 is an elevation of an alternative form of my invention in which the
inclined sided-rises are formed on the underside of a collar on the rotating and
rising and falling standard whilst the bracket is made to constitute the bottom
pivot for the standard and carries a stationary peg which engages with one or other
of the gaps in the collar and determines the position of the curtain arm.
Figure 15 is a vertical section of Figure 14.

page_text: a is the bedstead pillar, 63 the standard carrying the curtain arm and a is a
collar secured thereto, with the underside having keep gaps a³, a, a, separated
by double inclined formations a³, a³, whilst c is a fixed stud, carried upon the
pivot end 6, of a bearing bracket b, made fast to the said standard.
Figure 16 is an elevation of a modification of this arrangement, in which the
standard 63, has its lower end working (as in the first arrangement) in an eyed
bracket a, carried on the pillar a¹, and being provided with a fixed stud c,
adapted to engage with keep gaps a, a, a, in the collar 62, separated by double
inclined formations as, a³, on its lower edge, adapted when the standard is turned,
to wipe over the fixed stud, which lifts the said standard and then allows it to
drop, with another keep gap engaging over the keep pin.
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: :-
First: In swinging curtain arms for bedsteads, retaining the same in set
position and releasing it automatically therefrom when swung round, by a stud
or equivalent on the one element of the joint engaging with keep gaps, separated
by inclined plane formations or rises on the other element, and over which the
said stud traverses and makes a rising and falling movement in passing from
one keep gap to another.
Secondly-A joint for the standards of swinging curtain arms, in which
the lower end of the said standard is provided with a peg or stud, capable of
riding up and over double incline plane formations on the edge of an eyed
bracket, terminated by keep gaps for the peg, with the outer end gaps themselves
terminated by stop shoulders, substantially as and for the purpose described
and set forth.
Thirdly: In swinging curtain arms for. bedsteads, retaining the same in set
positions and automatically releasing them when swung round, by inclined
plane formations on the movable element of the joint, separated by keep gaps,
wiping over a fixed stud or pin on the other element of the joint, substantially
as described and set forth.
