PROVISIONAL SPECIFICATION.
Improvements relating to Means or Appliances for Supporting or
Holding Incandescent Gas Lighting Filaments.
I HENRY GARDNER, of 166 Fleet Street, in the City of London, Patent Agent do
hereby declare the nature of this invention which has been communicated to me from
abroad by The Society Francaise de L'Heliogene, Paris, France to be as follows:-
This invention has for object the manufacture and employment of gutter, flat,
round, or other shape, receivers, supports or holders for the fringe filaments used for
incandescent gas lighting purposes.
The gutter shape holders in strip or other form may be of such material as to be
pressed in contact to hold the filaments arranged therein or if of non-compressible
material such as a refractory clay a rod can be laced in or pushed to form a bight of
the filaments and so fix them in contact.
The ends of the strips if pliable can be bent or looped on to or over. winged
supporis from a burner or ends can be pin jointed to be moved to the necessary angle
for supporting the filaments and their holders.
The holders may be from a flat strip of metal say platinum, bent double or folded
along the central line and after the filaments are laid in or across the groove so
formed they can be pushed in and the edges of the metal clamped to retain the
filaments in position.

Improvements relating to Means or Appliances for Supporting or
Holding Incandescent Gas Lighting Filaments.
I HENRY GARDNER of 166 Fleet Street, in the City of London, Patent Agent, do
hereby declare the nature of this invention which has been communicated to me from
abroad by The Society Francaise de L'Heliogene, Paris, France and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
This invention has for object the manufacture and employment of gutter, flat,
round, or other shape receivers, supports, or holders, for the fringe filaments used for
incandescent gas lighting purposes.
The gutter shape holders in strip or other form may be of such material as to be
pressed in contact to hold the filaments arranged therein or if of non compressible
material such as a refractory clay a rod can be laced in or pushed to form a bight of
the filaments and so fix them in contact.
The ends of the strips if pliable can be bent or looped on to or over winged
supports from a burner, or ends can be pin jointed to be moved to the necessary angle
for supporting the filaments and their holders.
The holders may be from a flat strip of metal say platinum bent double or folded
along the central line and after the filaments are laid in across the groove so formed

page_text: they can be pushed in and the edges of the metal clamped to retain the filaments
in position.
I have appended the accompanying sheet of drawings as examples of my invention,
Figure 1 being a perspective elevation of a trough composed of refractory material
with the incandescent lighting filaments secured in position by a wire and suspended
in position by winged supports.
Figure 2 is a cross section of the trough showing how the wire forms a bight in the
filament to secure it in place.
Figure 3 is a perspective view of a filament holder composed of strip metal the
ends being turned outwards to secure it within the forked ends of the winged
supports and Figure 4 is a cross section of the strip metal holder showing the filament
clamped within it.
The gutter shaped holder A composed of refractory material has a rod B laced
through the ends C. C. after the filament D has been laid across and pushed to the
bottom of the gutter as shewn in Figure 2, whereby the said rod B securely holds the
filament D in contact with the bottom of the trough. The rod B may have eyes E or
be otherwise formed such as by bending or twisting to drop upon the pins F of the
wing supports G that are attached to the sleeve H to fit
upon the gas burner I.
If the filament holder be of strip metal such as platinum it is first doubled into
gutter shape for the filaments to be laid across same and be pushed to the bottom of
the gutter which is then clamped tightly together to hold the filaments in position as
in Figure 4.
The end J of the gutter strips A may be turned outwards as in Figure 3 for
lodgement of the gutter within forks K formed on the winged supports or said ends
may be twisted into eyes for lodgment upon wing supports similar to that shown in
Figure 1.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improvements hereinbefore referred to and consisting of gutter-shaped strips
bent to grip incandescent gas light filaments as a plume or fringe as and for the
purpose set forth.
