Improvements in Gas Chandeliers and other like Pendant Lamps
and Gas Fittings.
I, GEORGE JAMES WILLIAMS of Pershore Street, Birmingham in the County of
Warwick Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to dispense with the use of the ordinary water slide
now commonly employed for making a sound joint between the fixed and an adjustable
sliding part of a gas chandelier, pendant or gas fittings; by which improvements as
hereinafter described, no water or other slide is employed, which often times become
dangerous from want of water or from becoming leaky.
وو
My invention consists essentially in employing folding rods or hollow arms jointed
at or near their outer ends after the manner of what are known as "lazy tongues ;
that is, the body or the upper portion of the movable part of a gas chandelier or
pendant is suspended from rods or arms pivoted or jointed at their ends so as to admit
of folding up or opening out in a vertical direction, consequent on the raising and
lowering of a chandelier or the like, and which said arms or rods have gas ways through
two of them, or through all of them, for the passage of gas, in whatever position the
parts may be in.
In carrying out my invention, I will describe it in connection with a gas chandelier.
I take an ordinary chandelier, with a gas way through it leading to the arms, and
to the summit of the body, or to that part commonly called the cup, I joint the lower
extremities of two rods or arms, of a system of four arms, which are all jointed
together at their extremities, so that when partially opened out, they make or enclose
a lozenge figure; and to the upper extremity of this system of jointed rods, a ball or
socket joint carried by the sealing plate is connected, and to which said sealing plate,
pulleys over which the chains of usual counterpoise weights pass. The joints of the
rods may be of the usual conical plug and socket kind, with a continuous gas way
through them, and the said joints may be made in such a way, that the rods may be
made to lie in the same plane, or they may be made to lie in overlapping planes; or
the whole of the joints may be made of a knuckle or ball type, instead of the swivelling
plug kind as described.

page_text: The upper terminal ends of the weight chains may be connected to the body of the
chandelier or to the arms.
On the raising of a chandelier, the arms interposed between it and the sealing plate
are made to fold up more or less on the joint centres, while the lowering of the said
chandelier causes the arms to open out or distend themselves in a vertical direction,
thereby doing away with water or cork slide joints, which are now in common use.
Chandeliers, pendants and the like provided with my improvements, are perfectly
free from danger, inasmuch as the joint centres are plugs or metallic joints, which
admit of the arm collapsing or folding up when moved in one direction and extending
themselves by opening out when moved in the reverse direction.
Instead of employing four rods as described, eight or other even number may be
used; and further, the gas way in one of the joints near the sealing plate may be so
channelled, that on the chandelier being raised or pushed up to its fullest extent, the
gas from the service pipe is cut off.
For single arm pendants, I may only employ two jointed gas way rods which fold
up and open out after the manner of a rule joint.
The folding or collapsing gas-way arms aforesaid may be made if necessary to form
a part of the body of a chandelier.

Improvements in Gas Chandeliers and other like Pendant Lamps :
and Gas Fittings.
1, GEORGE JAMES WILLIAMS of Pershore Street Birmingham, in the County of
Warwick, 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:-
The object of this invention is to render adjustable gas chandeliers, gas lamps and
gas fittings, perfectly safe, or free from escape or leakage of gas when in use.
By my invention, ordinary water slides, cork slides or other means commonly
employed, for producing sound joints, are dispensed with.
My invention consists essentially in employing gas-way folding rods or arms,
jointed at or near their outer ends; that is, the outer ends of the rods are jointed to
the movable part of a gas chandelier, pendant and the like, and to a depending gas-
way pipe leading from the ceiling plate, while their inner ends are jointed to inter-

page_text: vening gas-plugs, or joint centres. Thus, the movable part of the chandelier or
pendant is suspended from jointed rods or arms, which admit of folding up or opening
out in a vertical direction, consequent on the said chandelier or pendant requiring to
be raised and lowered.
Figure 1 represents in front elevation, a gas chandelier, provided with an adjustable
and folding gas connection, constructed according to my invention; the said chandelier
is shown raised, and the adjustable connection, consisting of folding gas-way arms,
collapsed or nearly so. Figure 2 shows a like view as figure 1, but with the body of
the chandelier lowered, and the gas-way arms expanded or opened out. Figure 3
represents a plan of the upper side of the said chandelier, showing the depending
down-pipe leading from the ceiling plate, in section. Figure 4 represents partly in
elevation, and partly in section, the adjustable gas-way connection, upon a larger
scale; this view represents the coupled arms on one side, in complete section, while
the coupled arins on the other side, are shown in elevation. Figure 5 shows a top
side plan of figure 4, but with one of the arms, and the joint connection in section.
Figure 6 represents a modification, in which the arms or rods are made to cross each
other, after the manner of what are known as "lazy tongs." Figure 7 also represents
another modification, in which the joint connection is made to form the body, or that
part of the chandelier, coming in juxta position with the arms.
The same letters of reference indicate corresponding parts in the several figures of
the drawings.
a is the body of the chandelier, and a² are the arms; and proceeding upwardly
from the said body and armis part, is a pillar a³, surmounted by a cap a¹. b is a
ceiling plate, and 62 a depending gas-way pipe, connected in the usual way to the
part b, by a ball and socket joint. This depending gas-way has also at its lower end,
a hollow enclosing cap 63, and between the said caps a', and 63, of the said movable
and fixed parts, is an adjustable gas-way connection c, consisting of folding arms c¹,
connected at their inner ends, to gas-way plugs or joints e², carried by the parts a³,
respectively.
63
The outer ends of the said gas-way rods, are connected to plugs or joint centres c³ ;
so that on the chandelier requiring to be raised or lowered, or its position readjusted,
the arms interposed between it and the ceiling depending pipe, are made to fold up,
or open out upon their joint centres, thereby dispensing with the use of water or cork
slides as commonly employed.
Chandeliers, pendants, gas-fittings and the like provided with my improvements,
are perfectly free from danger, inasmuch as the arms, or one set of them, are gas-
way passages, through which gas is allowed to pass, from the supply pipe to the
chandelier.
In figure 1, the adjustable gas connection is represented with three sets of arms,
but one set only of them is used as a gas-way, while the others are employed for forming
the proper connecting support.
Instead of three arms, two may be used, with gas-ways through one set, or through
both sets; and it matters not in what position the chandelier is in, the gas passages
are always free.
The gas joint I prefer to use, is best seen in the sections figures 4 and 5, in which
the plug is partially divided about its middle, and with the stem of one part, passing
into a like socket in the other part; so that one arm of a pair of arms, is connected to
one part of the joint, while the other arm, is connected to the other part of the joint.
Ordinary balance weights d with chains passing over pulleys, and with the inner
ends of the said chains, connected with the body or pillar of the chandelier, is
employed.
Figure 6 represents a modification, consisting of gas-way arms, crossing each other,
and jointed at c³, c*.
In figure 7, the lower portion of the pillar, and the arms respectively, are provided
with bosses or hollow caps, to which the outer ends of gas-way jointed arms are
connected; so that in this particular form, the pillar part remains stationary, while the
suspended arms are rendered adjustable.

page_text: If necessary, the plugs of the joint centres, may be so arranged, that on the
chandelier being pushed up to its fullest extent, then gas is cut off from the service
pipe.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
First An adjustable gas connection for gas chandeliers, gas pendants, and other
like pendant gas fittings as hereinbefore described and illustrated in the several figures
of the drawings; that is to say, making an adjustable connection by means of folding
gas-way arms or rods, connected together, jointed and interposed between the fixed and
movable parts, of the articles as aforesaid, substantially as described and set forth in
figures 1, 2, 3, 4 and 5 of the accompanying drawings.
Secondly-Forming the parts as into box ends, whereto the inner ends of the
jointed arms are respectively connected, as described and illustrated.
Thirdly The construction and arrangement of the inner and outer joints, herein
described, and connections in combination with the gas-way folding arms or rods as
set forth.
Fourthly-Interposing between the fixed and movable parts of gas chandeliers
and the like, of a system of gas-way arins or rods, jointed and connected together,
substantially as described and set forth in figure 6.
Fifthly Interposing between the body and a fixed pillar connected with the
ceiling plate, of a system of gas-way jointed rods, substantially as described and set
forth in Figure 7.
