Agents, do hereby declare the nature of the said Invention for “AN IMPROVED
EXTENSIBLE BRACKET ARM FOR SUPPORTING CANDLESTICKS, MIRRORS AND OTHER

This Invention relates to a self coiling extensible bracket arm for supporting
candlesticks mirrors and other objects. The bracket arm which is ornamental as
well as useful and is equally strong whether in its extended or in its coiled or
collapsed position is represented in the accompanying drawing as used for a
candle holder Figures 1 and 2 respectively show it in its coiled and extended
positions, figures 4, 5 and 7 show details of parts and figure 6 a cross section
on a larger scale
The bracket arm consists of two distinct main parts A and B of which the latter
forms a guide for the former. The self coiling arm A is constructed of a chain of
links formed of plates jointed together by spring Joints and adapted to slide upon
the guide of the part B and provided with latches for connecting the links rigidly
when the arm is extended and adapted when pushed backwards to assume the
coiled form represented in the drawings
Each link of the arm A is composed of a pair of ornamental cheek plates y, of
the form shown in dotted lines, a pair of joint plates n, of the form shown having
at one end a semicircular ear to receive a joint pin or rivet a a by which said
plates n are jointed to the corresponding semicircular ears of the cheek plates y, of
the adjacent link, a pair of intermediate plates r, and a single central plate m, all
having semi circular recesses at their ends to form circular boxes between adjacent
links to contain a coiled spring d, as shown in figure 7 the parts y, y, n, n, r, T,
and m, being all rivetted together. Each link further comprises a pair of plates e

plate being rivetted together and to the adjacent cheek plate y, so as to leave a
clear space between the plates for the purpose hereafter described Each link 18
provided with a latch a pivoted between plates 2 and y and adapted to engage by
its hooked end g'with a notch fin the plate e of the adjacent link as shown in
figure 4 The part B consists of a short arm w, swinging on a joint and carried
by the wall plate or rose t The arm w has a central web v provided with a pair
of guide bars u one at either side of the web and a pair of plates o, acting on the
latches a as hereafter described
The jointed arm A slides on the part B the web v passing between the plates &
and between the lower parts of the plates r the guide bars u, passing between the
lower edges of plates r and the upper edges of plates and e all as shown in
figure 6 In pushing the jointed arm A backwards along the guide arm B the
latches a in passing over the latch trippers o come in contact therewith by their
tail ends thus releasing g from notch f of the preceding link and permitting the
links to follow the upwardly curved form of the rear ends of the guide bars u.
This direction they tend to take by the springs & tending to force the links apart
so that on pushing the arm A entirely inwards it becomes completely coiled up by
the links assuming the position shown in figure 1 On drawing the jointed arm A
forwards the reverse action of the latches takes place and in passing forward over o
they become engaged with the notches ƒ so as to lock the links together and render
the arm A rigid.
The socket & supporting the candle holder b, c or other object is attached to the
first link of the arm by bars a ≈ and rivets b, b, b, b, a space p being left between
bars x, in which the guide bars u are received when the arm is pushed back as
shown in figure 1

I, ALEXANDER MELVILLE CLARK, of the firm of A. M and Wm Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this invention (a communication to me
from abroad by Gebruder Hollweg, of Barmen, Germany, Manufacturers, through
their Agents, Wirth and Company Frankfort on the Main, in the Empire of
Germany, 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 a self coiling extensible bracket arm for supporting
candlesticks, mirrors, and other objects The bracket arm, which is ornamental s
well as useful, and is equally strong, whether in its extended, or in its coiled or
collapsed position, is represented in the accompanying Drawings as used for a
Candle-holder.
Figures 1 and 2 respectively show it in its coiled and extended positions
Figures 345 and 7 show details of parts, and Figure 6 a cross section on a
larger scale
The bracket arm consists of two distinct main parts A and B of which the latter
forms a guide for the former The self-coiling arm A is constructed of a chain of
links formed of plates jointed together by spring joints, and adapted to slide upon
the guide of the part B, and provided with latches for connecting the links rigidly
when the arm is extended and adapted, when pushed backwards, to assume the
coiled form represented in the Drawings Each link C of the arm A is composed
of a pair of ornamental cheek-plates y of the form shown in dotted lines, a pair of
Joint-plates n of the form shown, having at one end a semi-circular ear to receive
a joint-pin, or rivet, a a by which said plates n are jointed to the corresponding
semicircular ears of the cheek plates y of the adjacent link, a pair of intermediate
plates, r, and a single central plate m all having semicircular recesses at their ends
to form circular boxes between adjacent links to contain a coiled spring d, as
shown in Figure 7 the parts yynn rr and m being all rivetted together Each
link further comprises a pair of plates e and a pair of inner plates 2 of the respec-
tive forms shown, one place e and one plate being rivetted together and to the
adjacent cheek plate y so as to leave a clear space between the plates 2 for the
purpose hereafter described Each link is provided with a latch a pivoted between
plates and y and adapted to engage, by its hooked end g, with a notch f in the
plate e of the adjacent link as shown in Figure 4 The part B consists of a short
arm w swinging on a joint and carried by the wall plate, or rose, t
The arm w
has a central web v provided with a pair of guide bars u one at either side of the
web and a pair of plates o acting on the latches a as hereafter described The
Jointed arm A slides on the part B, the web passing between the plates and
between the lower parts of the plates r, the guide bars u passing between the lower
edges of plates and the upper edges of plates and e, all as shown in Figure 6
In pushing the jointed arm A backwards along the guide arm B, the latches a in

This
passing over the latch-trippers o come in contact therewith by their tail ends, thus
releasing hook g from notch f of the preceding link, and permitting the links to
follow the upwardly curved form of the rear ends of the guide bars u
direction they tend to take by the springs & tending to force the links apart, so
that on pushing the arm A entirely inwards it becomes completely coiled up by
the links assuming the position shown in Figure 1 On drawing the jointed arm A
forwards, the reverse action of the latches takes place, and in passing forwards
over o they become engaged with the notches fso as to lock the links together, and
render the arm A rigid The socket & supporting the candle-holder bc, or other
object, is attached to the first link of the arin by bars xz and rivets b b b b, a l
space p being left between bars in which the guide bars u are received when
the arm is pushed back as shown in Figure 1
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st In an extensible bracket arm the links C in combination with the guide
arm B, and guide bars u which serve to guide the links C as the bracket is drawn
in, or out
2nd The connection of the Links C, one with another, by the spiral springs d
effecting a coiling up of the links upon the arm being pushed inwards
3rd The latches a attached to the links C in combination with the latch-trippers o,
all substantially in the manner, and for the purpose as described and shown in the
Drawings
