PROVISIONAL SPECIFICATION.
Improvements in Chandeliers, Gaseliers, Gas Pendants, and Gas
Brackets, which Improvements are also applicable to other
Hanging Lamps.
I, THOMAS FORD, of Victoria Works, Emily Street, Highgate, Birmingham in
the County of Warwick, Chandelier Manufacturer, do hereby declare the nature
of this invention to be as follows:-
My invention has reference to chandeliers, gaseliers, gas pendents and gas
brackets and the like in which the raising and lowering of the flame or source
of light or of more than one of the same when there are several is effected by
means of jointed arms having motion in a vertical plane.
I will describe my invention as applied to one arm of a gaselier the said arm
being jointed to the central or down pipe.
I form the said jointed arm preferably of a shape somewhat resembling the
letter S the said S shaped arm being jointed at its inner end to the said down
pipe and at its outer end to the vertical or pendent arm carrying the burner or
lamp. The joints at the ends of the S shaped arm are formed with the ordinary
passages by which gas passes from the down pipe to the lamp or burner. To
the upper side of the S shaped jointed arm and at a short distance from its
inner end a curved elastic metal strip or bar is connected by means of a knuckle
joint the said strip being concave to the S shaped jointed arm. The said elastic
strip passes through two guiding loops fixed to the down pipe of the gaselier
above the inner end of the S shaped jointed arm. The lower guiding loop is
provided with a pair of anti-friction rollers and the upper loop has at front a
clamping screw by which sufficient resistance is placed upon the elastic strip to
prevent its free movement.
When it is desired to raise or lower the lamp or burner it is only necessary
to turn the S shaped arm so as to raise or lower the pendent arm carried by its
outer end.
In applying my invention to a gas or other bracket the S shaped arm is jointed
to a short horizontal arm carried by the wall plate and the guiding loops for
the elastic strip bereinbefore referred to are also carried by the said wall plate
but the short horizontal arm, to which the S shaped arm is jointed, and the
guiding loops are preferably jointed to the wall plate so as to permit of the
bracket being turned in a horizontal plane, the short horizontal arm and guiding
loops having vertical axes.
The application of my invention to the suspending of the lamps of chandeliers,
gas pendents, electroliers and lamps burning light or volatile oils differs in no
essential respect from its application to the method of suspending the arm of a
gaselier as hereinbefore described.

1, THOMAS FORD, of Victoria Works, Emily Street, Highgate, Birmingham in
the County of Warwick, Chandelier Manufacturer, do hereby declare the nature of
my invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has reference to chandeliers, gaseliers, gas pendants and gas
brackets and the like in which the raising and lowering of the flame or source of
light, or of more than one of the same when there are several, is effected by means
of jointed arms having motion in a vertical plane.
I will describe my invention as applied to one arm of a gaselier the said arm
being jointed to the central or down pipe.
I form the said jointed arm preferably of a shape somewhat resembling the
letter S the said S shaped arm being jointed at its inner end to the said down pipe
and at its outer end to the vertical or pendent arm carrying the burner or lamp.
The joints at the ends of the S shaped arm are formed with the ordinary passages
by which gas passes from the down pipe to the lamp or burner. To the upper side
of the shaped jointed arm and at a short distance from its inner end, a curved
metallic tube or elastic strip, bar or arm is connected by means of a knuckle joint,
the said tube, bar or arm being concave to the S shaped jointed arm. The said
tube, bar or arm passes through one or more guiding loops fixed to the down pipe
of the gaselier above the inner end of the S shaped jointed arm.
One of the said
guiding loops has at front a clamping or pressure screw by which sufficient
resistance is placed upon the tube, bar or arm to prevent its free movement. The
lower guiding loop when two are used is provided with a pair of anti-friction
rollers.
When it is desired to raise or lower the lamp or burner it is only necessary to
turn the S shaped arm so as to raise or lower the pendent arm carried by its
outer end.
In applying my invention to a gas or other bracket the S shaped arm is jointed
to a short horizontal arm carried by the wall plate or pateras and the guiding loop
or loops for the curved tube, elastic strip bar or arm hereinbefore referred to is
also carried by the said wall plate or pateras, but the said short horizontal arm to
which the S shaped arm and guiding loops are jointed are preferably connected to
the wall plate or pateras by swing plugs so as to permit the bracket to turn in a
horizontal plane.
Figure 1 of the accompanying drawings represents in elevation a two light
gaselier containing my improvements and Figure 2 represents, drawn to a larger
scale, a horizontal section through the down pipe and parts connected therewith,
the said section being taken on the line a, a Figure 1.
Figures 3 and 4 represent in elevation a gas bracket containing my improvements
and Figure 5 represents a horizontal section of a portion of the same drawn to a
larger scale, the said section being taken on the line
y, y Figure 3.
The same letters of reference indicate the same parts in the several figures of
the drawings.
I will first describe the gaselier Figures 1 and 2.
To the lower end of the central or down pipe a joint the intermediate S shaped
or scroll arms of the gaselier, the inner joints of the said scroll arins being
marked b. To the outer end 2 of each of the scroll arms the pendent tube or
frame c carrying the globe and burner is jointed, the said pendent tube or frame

page_text: hanging vertically in whatever position the scroll arm 6 may occupy. Jointed to.
each of the scroll arms bat d' is the curved tube d the said tube passing through
the guiding loop e carried by the central or down pipe a. Through the front of
the guiding loops e pressure thumb screws f pass by adjusting which sufficient
frictional resistance may be put upon the curved tubes d to retain or support themi
in any position the said arms d may be pulled or pushed by the lowering or raising
of the jointed arms b, c of the gaselier. The ends of the screws fand the back
parts of the guiding loops e are provided with india-rubber, felt or other like-
pads g, g so as to prevent the abrasion or scratching of the curved tubes d on their
motion through the guiding loops e.
It will be understood from the description herein before given that in order to
lower or raise one or other or both of the lights of the gaselier it is only necessary
to pull down or push up the pendent tubes until the lights are in the position.
desired when on the release of the pendent tubes they will be retained by the
curved supporting tubes or arms d and pressure screws. One of the pendent
tubes c is indicated in a lowered position in dotted lines in Figure 1.

By the employment of the curved arms or tubes & and pressure screws f
bereinbefore described and illustrated the jointed arms of the gaselier are sup-
ported in any position and the use of counter-balance weights for that purpose is
dispensed with.
I will now describe the gas bracket Figures 3, 4 and 5.
Figure 3 represents the bracket with its jointed arms in their pressed in and
raised position and Figure 4 represents the said bracket with its jointed arms in
their pulled out and lowered position.
In constructing the gas bracket I provide the wall plate or pateras with two-
swing plugs marked respectively i, . To the lower swing plug i, which is
provided with a gas way or passage, the inner end of the scroll arm bis jointed
at and the upper swing plug carries the guiding loop e and pressure screw for
the curved supporting tube or arm d. The jointed arms b, c of the bracket are
capable, in addition to their motion in a vertical plane, of a motion in a horizontal
plane, the parts of the bracket turning on the vertical axes of the swing plugs i,
as is indicated in dotted lines in Figure 5, and occupying a position on one or other
side of the wall plate or pateras h. In other respects the arms and other parts of
the bracket do not differ from corresponding parts of the gaselier and are marked
with the same letters of reference.
Although I have described and represented a curved retaining tube for the
S shaped jointed arm and a single guiding loop and clamping screw for the same.
yet I wish it to be understood that an elastic metallic strip or bar may be sub-
stituted for the said curved retaining tube, the said strip passing preferably
through two guiding loops situated one above the other, the upper loop being
provided with the clamping screw.
The application of my invention to the suspending of the lamps of chandeliers,.
gas pendants, electroliers and lamps burning light or volatile oils differs in no.
essential respect from its application to the method of suspending the arms of a
gaselier and gas bracket as herein before described and illustrated.
Having now particularly described and ascertained the nature of my inven--
tion and in what manner the same is to be performed I declare that I claim
as my invention :-
The arrangements or combinations of parts of chandeliers, gaseliers, gas pendants
and other hanging lamps and brackets herein before described and illustrated in the
accompanying drawings; that is to say, the combination with two jointed arms,.
the outer or pendent arm being jointed to the end of the inner or scroll arm and
the latter to the down pipe of the chandelier or the like or to the wall plate of the
bracket so as to be capable of motion in a vertical plane, of a curved tube or
elastic strip or bar jointed at its lower end to the scroll arm, the upper end
working in a guiding and frictional retaining loop or loops on the down pipe of

page_text: the chandelier or the like or wall plate of the bracket for supporting the said
jointed arms in any position to which they may be brought substantially as
described and illustrated.
