1, GEORGES ANTOINE TABOURIN, of 37, Rue de Passy, Paris, in the Republic of
France, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an electric lamp combined with apparatus driven by a gas
motor for generating the electricity therefor.
The base or pedestal of the lamp is made hollow and is provided with a removeable
plate or a door.
The standard or column of the lamp is curved over at the top and has suspended
therefrom an electric voltaic arc lamp or other suitable kind of electric lamp.
Inside the base or pedestal I fix a dynamo electric machine for producing the
electric currents and a rotary or other gas motor drives the dynamo by means of an
arrangement of three driving bands and pulleys of different sizes to allow of different
speeds being obtained.
The rotary gas motor receives the gas for actuating it through a supply tube which
communicates with an ordinary gas main.
The consumed or burned gases are conducted outside through a discharge tube.
The rotary gas motor I prefer to employ is that patented to me in France under
No. 179,736 dated the 18th November 1886. It is adapted for the operation of the
various parts of my lamp in preference to other gas motors by reason of its small
dimensions and its simplicity and more especially by reason of its self-cooling
character, which cooling is effected by the burnt-gas exhaust drawing in fresh air
around the cylinder through a draught tube communicating with the exhaust tube.
Any other direct acting gas-motor of small size can however be employed for
actuating my improved lamp.
The lamp is fixed in the required place and is put in communication with the
gas supply pipe by means of the bereinbefore described supply tube on which is
fixed a small branch pipe conveying the gas to the jet and placed under the cylinder
of the motor.
The currents produced by the dynamo flow upwards through wires to the lamp
and produce the electric light.

page_text: By my invention I obtain novel results and advantages from the application of
known mechanical contrivances and physical effects, the said contrivances being
combined, arranged, and enclosed within the base of an electric lamp in such a
manner as to constitute a self contained lighting apparatus which is entirely novel in
its arrangement, effects, and results, that is to say,
In its entirety it constitutes a complete and novel combined electric lamp and
generator of electricity.
Having but a single light it possesses all the advantages accruing from the pro-
duction of electric light for a single lamp and without any of the numerous losses
inherent to the division of the electric currents. It is in no way connected with a
central depot for the generation of electricity but furnishes by itself the electric light
and is its own generator.
By my invention I can obtain a number of lights without division of the electric
currents and without the losses entailed thereby. As the apparatus produces the
electric current on the spot where the light is required an economy is effected by
avoiding the expense of electric conducting cables and channels or protectors for the
заще.
For operating the apparatuses they can be connected to gas mains of the smallest
towns, and no great expense need be incurred for connecting and working all the
lamps of a public thoroughfare. The lights can be multiplied that is to say the
motive power can be increased but by dividing this power or employing a number
of motors a great economy is effected. My lamp not being, like electric lighting
apparatuses hitherto in use, supplied from branches of an electric conducting cable,
the working or the extinction of one of a number serving to light a public
thoroughfare would not affect the others.
The electric current being employed immediately on the spot where it is generated
that is to say having only to pass from the base of the lamp to the top, the distance is
inconsiderable and no loss of the electric current takes place as hitherto on account of
the distance which separates the electric generator from the lamp. This loss, under
existing systems, sometimes amounts to 15 per cent. of the currents generated.
Therefore the loss of the electric currents due to their division being as 1 to 5 my
combined generator and lamp provides five times more light for the same cost. By
comparison with certain cases where the generators are separated by long distances
from the lamps, my system of lighting will allow of obtaining ten times more light.
My electric lamp besides requiring no electric conducting cable and distributor of the
currents, and thereby economising expense also for that reason prevents the loss of
electricity due to the connections as well as to insufficient insulation.

A Combined Generator of Electricity and Electric Lamp.
I, GEORGES ANTOINE TABOURIN, of 37, Rue de Passy, Paris, in the Republic of
France, Engineer, 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 :-
This invention relates to an electric lamp combined with apparatus driven by a gas
motor for generating the electricity therefor.
The accompanying drawing represents an elevation of the combined generator and
lamp one of the removeable side plates or doors of the base or pedestal which is made
hollow, being removed in order to illustrate the mechanism enclosed therein. This
detached side plate or door is represented in elevation at the left-hand side of the
drawing.
The standard or column B of the lamp is curved over at the top and has suspended
therefrom an electric voltaic arc lamp A or other suitable kind of electric lamp.
Cis the hollow base or pedestal of the lamp, and D, D are the removeable side
plates or doors secured to the base or pedestal by means of bolts and nuts E as
shown.
Inside the base or pedestal I fix to one of the plates D a dynamo electric machine F
for producing the electric currents and a small rotary gas motor G or other gas
motor of appropriate dimensions and capable of producing at least one or two horse
power. This rotary or other motor may be single or double, that is to say, coupled
to a second motor placed by its side in order to produce a more regular light.
The single or double motor contained in the base drives the dynamo F by means of
an arrangement of three driving bands a, a', a" and pulleys of different sizes to allow
of different speeds being obtained.
Three of these pulleys 6, 61, 611 are shown in the drawing and the three others are
concealed from view by the dynamo and the rotary gas motor.
The rotary gas motor G receives the gas for actuating it through a supply tube H
which communicates with an ordinary gas main.
The consumed or burned gases are conducted outside through a discharge tube I.
The rotary gas motor I prefer to employ is that patented to me in France under
No. 179,736, dated the 18th November 1886. It is adapted for the operation of the
various parts of my lamp in preference to other gas motors by reason of its small
dimensions and its simplicity and more especially by reason of its self-cooling

page_text: character, which cooling is effected by the burnt-gas exhaust drawing in fresh air
around the cylinder through a draught tube f communicating with the exhaust
tube I.
The lamp is fixed in the required place and is put in communication with the gas
supply pipe by means of the tube H on which is fixed a small branch pipe J conveying
the gas to the jet and placed under the cylinder of the motor G.
The currents produced by the dynamo flow upwards through wires d, d¹ to the
lamp A and produce the electric light.
By my invention I obtain novel results and advantages from the application of
known mechanical contrivances and physical effects, the said contrivances being
combined, arranged, and enclosed within the base of an electric lamp in such a
manner as to constitute a self contained lighting apparatus which is entirely novel in
its arrangement, effects and results, that is to say:
In its entirety it constitutes a complete and novel combined electric lamp and
generator of electricity.
Having but a single light it possesses all the advantages accruing from the
production of electric light for a single lamp and without any of the numerous
losses inherent to the division of the electric currents. It is in no way connected
with a central depot for the generation of electricity but furnishes by itself the electric
light and is its own generator.
By my invention I can obtain a number of lights without division of the electric
currents and without the losses entailed thereby. As the apparatus produces the
electric current on the spot where the light is required an economy is effected by
avoiding the expense of electric conducting cables and channels or protectors for the
same.
For operating the apparatuses they can be connected to gas mains of the smallest
towns, and no great expense need be incurred for connecting and working all the
lamps of a public thoroughfare. The lights can be multiplied, that is to say, the
motive power can be increased but by dividing this power or employing a number
of motors, a great economy is effected. My lamp not being, like electric lighting
apparatuses hitherto in use, supplied from branches of an electric conducting cable,
the working or the extinction of one of a number serving to light a public
thoroughfare would not affect the others.
The electric current being employed immediately on the spot where it is generated,
that is to say, having only to pass from the base of the lamp to the top, the distance
is inconsiderable and no loss of the electric current takes place as hitherto on
account of the distance which separates the electric generator from the lamp. This
loss, under existing systems, sometimes amounts to 15 per cent. of the currents
generated. Therefore the loss of the electric currents due to their division being
as 1 to 5 my combined generator and lamp provides five times more light for the
same cost. By comparison with certain cases where the generators are separated
by long distances from the lamps, my system of lighting will allow of obtaining ten
times more light. My electric lamp besides requiring no electric conducting cable
and distributor of the currents, and thereby economising expense also for that reason
prevents the loss of electricity due to the connections as well as to insufficient
insulation.
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.) The arrangement of parts forming my improved combined generator of
electricity and electric lamp in which gas or hydrocarbons are employed as the
source of power.
(2.) A combined generator of electricity and electric lamp in which the generator
of electricity is driven by a motor actuated by lighting gas of towns or by other
hydrocarbons gasefied or not.

page_text: (3.) The employment of a series of the herein described electric lighting
apparatuses for furnishing a number of lights, the said apparatuses being connected
together by the general supply system of the lighting gas of towns instead of by
a metal conductor of electric currents whereby a number of lights are obtained
without a division of the electric current but with a division of the generating
power or producer of the said currents the said producer being the lighting gas
which is distributed through public thoroughfares rendering unnecessary any pro-
vision for electric cables or any central depot for the production of electricity.
