PROVISIONAL SPECIFICATION.
Improvements in Electric Glow Lamps.
1, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
inunication to me from abroad by Wilhelm Wiklund, of 44 Gamla Kungsholms-
brogatan, Stockholm N., Sweden, Electrical Engineer) to be as follows:-
This invention for improvements in electric glow lamps is an arrangement by
which the carbon is supported preventing same from swaying to side of bulb and
means of collecting the residue from burning of carbon ensuring clearness of glass
on the inside.
To prevent the carbon from leaning against or near the glass, is fixed inside
through neck of lamp a small rod or wire, the carbon being threaded through a
small loop or a hole in top end and made fast, this rod or wire can be made of
glass or other suitable material, but when made of steel, iron or other composition
it will then collect or attract the residue from carbon thus ensuring clearness of
glass on the inside.
The carbon can also be constructed or arranged with twist on both sides of rod
forming spiral lines, this has that effect the rod or wire being magnetic when
current passes through the carbon.
The magnetism by steel, iron or metal of other composition causes the coal
particles from the carbon to be collected on the rod or wire, the carbon being nearer
than to the glass, therefore the glass on inside of lamp remains clear all through
which is not the case with other glow lamps now in common use.
It will be understood that the foregoing is given by way of illustration and that
the shapes materials and parts may be varied in many ways within the scope of my
invention.

Improvements in Electric Glow Lamps.
1, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, W., in the County
of London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Wilhelm Wiklund, of 44 Gamla Kungsholms-
brogatan, Stockholm, N., Sweden, Electrical Engineer,) and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention for improvements in electric glow lamps is an arrangement by
which the carbon is supported preventing same from swaying to side of bulb and
means of collecting the residue from burning of carbon ensuring clearness of glass
on the inside.
In the accompanying drawing Figs. 1, and 2, are shewn different types.
To prevent the carbon a from leaning against or near the glass, is fixed inside
through neck of lamp a small rod or wire b, the carbon being threaded through a
small loop c in the top and made fast as in Fig. 1, this rod or wire 6 can be made
of glass or any other suitable material, but when made of steel, iron or other

page_text: composition it will then collect or attract the residue from carbon thus ensuring
clearness of glass on the inside.
The carbon a can also be constructed or arranged with a twist on both sides of
the rod forming spiral lines as shewn in Fig. 2, this has that effect, the rod or
wire being magnetic when current passes through the carbon. The magnetism
by steel, iron, or metal of other compositions causes the coal particles from the
carbon to be collected on the rod or wire, the carbon being nearer than to the glass,
therefore the glass on inside of lamp remains clear all through, which is not the
case with other glow lamps now in common use.
It will be understood that the coils, spirals or twists of the carbon may be of
any suitable shape otherwise that what is shewn on the drawing.
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 :-
1. In electric glow lamps, the combination of a metal or wire provided with
a loop or hole through which the carbon is threaded and made fast thereby for
supporting the same, with the carbon and other fittings and glass bulb, substantially
as herein described and according to the accompanying drawing.
2. In electric glow lamps, the combination of the rod or wire of any magnetic
material and carbon twisted on both sides forming spiral lines so that the rod or
wire when the lamp is burning will collect or attract the residue from carbon
thereby keeping the glass bulb clear, substantially as herein described and according
to the accompanying drawing.
3. In electric glow lamps, the combination of the rod or wire, and the carbon
any
suitable formation, situated in a glass bulb, substantially as herein described
and for the purpose specified.
