Geddington Kettering do hereby declare the nature of our invention for
"A SELFACTING REGULATING MACHINE FOR EXTINGUISHING AND RELIGHTING GAS
LAMPS FOR STREET PURPOSES to be as follows:-
"'
The Machine can be made to fit any ordinary Street Lamp, the works are fixed
in a light frame so as to be easily put in or taken out of, the Lamp without taking
to pieces, and arranged so as not to obstruct the light, made on a cheap and durable
principle, works by spiral wires in the teeth of small wheels, with a Fan driven by
Atmospheric power.
The small jet sufficient to keep the Machine going to time, is regulated by a
small thumb screw fixed in the pipe attached to the one in which the burner is
screwed, On the spindle of the last or slowest moving wheel is a narrow, circular
case of blocks made to slide backwards and forwards so as to put on as many hours
full light as may be required, and as the wheel revolves the blocks come in contact
and lift the arm connected with the Valve which supplies the burner-a small
wheel is placed at the end of the arm, which runs on the top of the blocks to hold
on the full light, and when it runs off the blocks the arm shuts the valve, leaving
only the small jet.
When the full light is turned on, the driving power is several. times stronger
than the small jet, but the extra speed is counteracted by brushes on the Governors
attached to the spindle of the Fan, rubbing on an India-rubber Cap, with pressure
in proportion to the extra driving power, and the brushes can be turned higher or
lower as required.

page_text: Lamp when it is lighted-A circular hole through the bottom of the Lamp is made
for the metal tube to go through, that the Machine may be screwed to the bottom
from underneath, so that little or no air can get in the Lamp only by way of the
metal tube on to the Fan, which causes it to revolve, and drive the Machinery.
C. C. are the Governors (attached to joints represented by dotted lines and fixed
near the top of the spindle of the Fan)-on each of the Governors is a small brush
made of bristles or stiff horse-hair and fix by a inoderately tight rivet, so as to give
the brushes a necessary slanting or upright position for the purpose of regulating
the speed of the Fan; the more slanting the brushes are set, the more liberty for
greater speed of Fan, and the more upright the brushes are set, the less liberty for
speed of Fan, and by this means the speed can be regulated when the full light is
turned on, to the same speed as when the small jet only is burning-On the spindle
of the Fan, is fixed a spiral worm forming an open screw, made of Steel wire, which
causes the Wheel D. to revolve.
D. is a Wheel about inch in diametre made of thin brass with 12 cogs or teeth,
and on the spindle of this wheel is fixed a spiral worm, forming an open screw,
causing the Wheel E. to revolve with twelve times less speed and consequently
with twelve tiines more power.
E. is a Wheel about an inch diametre made of thin brass and the same number
of cogs or teeth as Wheel D, on the spindle of this Wheel is fixed a spiral worm
forming a screw, which causes the Wheel F.-to revolve with twelve times less speed
than Wheel E. and consequently with twelve times more power.
F. is a Wheel 1 inches diametre made of thin brass, with 51 teeth, and revolves
once in 28 minutes; on the spindle of this Wheel is a worm which causes the
Wheel G to revolve.
'
G. is. à Wheel the same diametre' as F. with 51 teeth, and revolves once in
24 hours on the 'spindle of' Wheel G. is fixed a circular case of 24 blocks of box
wood, and revolves with the wheel G.
2. "
H. is the circular Case of 24. blocks with one pin running through each block and
rivetted on each side of the Case-The bottom, or rather that side of the blocks
nearest the spindle, slide in grooves under the pins which keeps them in proper
position; each block.can be seperately moved from one side of the Case to the other,
so as to come in contact with the friction wheel (fixed on the arm K. connected
with the Valve L. immediately over the inner side of the case of blocks, so as to
open or close the valve as the Case H. revolves. When the blocks are all put on
that side of the Case towards the door of the Lamp, they miss the friction Wheel
on the arm connected with the valve L, consequently leave, only the small jet
burning As many hours full light that may be required, so many blocks must be
removed to the other side to come in contact and open the valve, and turn on the
full light In the drawing, the blocks on the top of the Case are represented to be
on the outer side nearest the door of the Lamp and the remainder are represented
to be on the inner side.
I. is a small, tap for regulating supply of gas to small jet; this tap must be turned
on to supply sufficient gas to cause heat enough to elevate the Governors C. C.
with the brushes to slightly touch the India-rubber facing which is fixed under
Cap J. to an arm with a pivot hole for the top of spindle to Fan to work in.
The turning on of the gas affects the driving power in this way vizt It causes
more heat in the Lamp and larger jet, which consumes more air, consequently a
sharper draught up the tube on the vanes of Fan B. hence the necessity of
Governors C. C.. to check the extra speed.
J. is a circular plate of thin metal with India rubber facing for the brushes to
rub against, which they will do with pressure in proportion to the driving power,
and continue self regulating.
K. is an arm, withi friction wheel. at the end running on the case of blocks H.
when required to open the valve L.
F
I is the valve, which hangs on a pin through that end of the arm, in the tube
which the gas passes up to the burner, and represented in drawing by dotted lines.

page_text: The standards (in which the pivot holes for the spindles are made,) slide into the
Frame A. so that they may be moved higher or lower, as required to adjust the
works of the Machine.
The worms made of steel wire, work much easier, than if cut out of solid metal,
especially the worm on spindle of Fan, which moves at the greatest speed and least
power.
The chief novelties of the Invention are as under-
Vist 1st The method described for regulating the speed to the same time, against
different driving powers, from that caused by the small jet, and the full light.
2nd The blocks described for opening and closing the valve.

page_text: spindle of the Fan is fixed a spiral worm, forming an open screw, made of steel
wire, which causes the wheel D. to revolve.
D. is a wheel about 1/2 an inch in diametre made of thin Brass with 12 cogs or
teeth, and on the spindle of this wheel is fixed a spiral worm forming an open
screw, causing the wheel E to revolve with 12 times less speed and consequently
with 12 times more power.
E is a wheel about 1/2 an inch diametre made of thin brass and the same number
of cogs or teeth as wheel D, on the spindle of this wheel is fixed a spiral worm
forming a screw which causes the wheel F, to revolve with 12 times less speed
than E, and consequently with 12 times more power.
F is a wheel 1/2 inches diametre, made of thin brass with 51 teeth and revolves
once in 28 minutes, on the spindle of this wheel is a worm which causes the
wheel G, to revolve.
G is a wheel the same diametre as F. with 51 teeth and revolves once in
24 Hours, on the spindle of wheel G is fixed the wheel made of two thin plates of
brass with cork between about 3/16the thick as described above, and revolves with
the wheel G.
H is the wheel made of two thin plates of brass with cork between, with 96 pins
through, each pin can be reperately moved from one side of the wheel H to the
other, so as to come in contact with the lever connected with the valve, so as to
open or close the valve as the wheel H revolves, when the pins are all put on that
side of the wheel towards the door of the Lamp, they miss the lever on the spindle
connected with the valve L, consequently leave only the small jet burning, as
many hours, half hours, or quarters full light that may be required, so many pins
must be removed to the other side to come in contact with the lever and open the
valve to turn on the full light-In the drawing, the pins on the top part of the
wheel H are represented to be on the outer side nearest the door of the Lamp and
the remainder are represented to be on the inner side.
I. is a small screw for regulating supply of gas to small jet, and to regulate it to
keep the machine going to time, this screw must be turned on to supply sufficient
gas to cause heat enough to elevate the Governors C. C. with the brushes to slightly
touch the India-rubber facing which is fixed under cap J to an arm with a pivot
hole for the top of spindle to Fan to work in-The turning on of the gas affects
the driving power in this way, Vizt it causes more heat in the Lamp, and larger
jet, which consumes more air, consequently causing a sharper draught up the tube
on the vanes of Fan B, hence the necessity of Governors C. C. to check the extra
speed.
J. is a circular plate of thin metal with India-rubber facing for the brushes to
rub against, which they will do with pressure in proportion to the driving power,
and continue self regulating.
⋅
K is the spindle on which the valve is fixed with small lever at the end sliding
on the pins in wheel H when required to open the valve L.
L, is the valve inclosed in a square brass box, through which the gas passes up
to the burner and represented in drawing by dotted lines.
The standards (in which the pivot holes for spindles are made) slide in the
Frame A so that they may be moved higher or lower, as required to adjust the
works of the Machine.
The worms made of steel wire, work much easier, than if cut out of solid metal,
especially the worm on spindle of Fan, which moves at the greatest speed and least
power.
The chief novelties of the Invention are as under.
