An Improved Apparatus for Automatically Lighting and Extin-
guishing Street and other Gas Lamps, including the Incan-
descent and other Gas Contrivances, at any time desired.
ERNEST BLOMMART-MILES 1, Fairfield Road Grove Park Kent Medical Student do
hereby declare the nature of this invention to be as follows:-
I propose to do this by means of a self lighting burner such as John Frederick
Duke's, and by clockwork causing a circular guide to revolve, having a rim consisting
of a low level and a high level to hold the double flanged circumference of a wheel in
position to revolve thereon and to be raised and to fall by the action of the rim upon
the top of the circular revolving guide. Through the centre of the wheel a pin is
passed upon which it revolves the other end of the pin passes through a lever, or
other contrivance, which is attached to the valve or tap of the supply pipe, upon
which a weight, spring, or other contrivance is placed to shut and keep shut the
valve or tap to the supply pipe after the wheel falls from the high to the low level
and during its continuance upon the latter. Upon the inner end of the pin is a head
and the double flanged circumference of the wheel rises up an incline to the higher
level opening the valve or tap. The rim beneath the wheel proceeds by the power
of a clockwork arrangement. To meet the variations in the time for lighting and
extinguishing during the twenty four hours at various periods of the year, two slides
will be required to shift backwards or forwards to shorten or lengthen the high level
accerding to a shorter or a longer period required to keep the gas alight. These slides
when set will be fixed by stops to cause them to remain in the place to which they have
been shifted. The spring and wheels of the clock and other parts are to be
proportioned to the power necessary to keep the guide rotating and to perform the
actions already described. The circular guide revolves once round in twenty four hours
and its flat perpendicular face is divided into hours or other portions of time preferably
into twenty four either fastened or stamped upon it. The clockwork is to be made
to go for eight days or such period of time as may be required. This apparatus is to
be enclosed in a gas tight case of such shape as may be found necessary, having
a slide or door which when shut must be gas tight in order to set the slides and to
wind and regulate the clock. Upon the top of the gas tight case a self lighting
burner or a continuation pipe with the self lighting burner upon the top of it, may be
fixed. At the bottoin of the apparatus a connecting screw is fixed, to enable it to be
fixed on to any service or supply pipe.

I, ERNEST BLOMMART-MILES, of Grove Park, Kent, 1 Fairfield Road Medical
Student, 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 :-
I effect the automatic regulation of the supply of gas to a self lighting burner or
series of burners or gas consumers by means of a circular guide or disc and lever as
.hereinafter described.
The disc is furnished with a rim at right angles to its plane or the rim may he
attached to the periphery of the disc which rim is made of two portions of
different levels and the disc is made to revolve by means of clockwork once in
twenty four hours or any other period of time desired. The fall of the disc
is divided into twenty four equal divisions which are again sub-divided.
A wheel (which may be flanged) with its axle affixed to the end of one arm
of a pivoted lever placed upon the rim of the disc so that as the disc revolves the
lever remains steady whilst the wheel is on each portion of the rim, but is automatic
as the wheel passes from one lever to the other. The other end of the pivoted lever
is connected to the gas supply tap or valve. Whilst the wheel above referred to is
on the higher level of the rim the supply tap or valve is open and whilst the wheel is
on the lower level of the rim the supply tap or valve is closed or partially closed as
may be desired.
The arm of the lever to which the wheel is affixed is preferably weighted so as to
keep the wheel in contact with the disc and of course the clockwork has to be
regulated having regard to the friction of the wheel upon the disc.
of
The time during which the supply tap or valve is open is regulated by altering the
length of the higher portion of the rim. This is effected by means of forming
two sliding portions, which may be clamped in any desired position according to the
time which is required to keep the tap or valve open. The one end of the higher
level of the rim is levelled down to the lower level so that the wheel may easily pass
from one level to the other as the disc revolves.
The disc and the lever arrangement may be enclosed in a gas tight chamber, into
which the gas is admitted and from which it is cut off by the revolution of the disc, or
the tap or valve attached to the lever may be made to admit and cut off the gas to
and from a chamber behind the disc. The gas is taken to be consumed from the
Chamber by a continuation pipe.
In order that my invention may be the more readily understood I have annexed
the accompanying drawings in which Fig. I is a side view of the adjustable sliding
higher level portions of the rim Fig. II. is a plan of the disc wheel and lever Fig. III.
gives a sectional view of the sliding higher level portions of the rim.
Like letters refer to like parts throughout the drawing.
A is the graduated disc caused to revolve by clockwork once in twenty four hours.
BB are the sliding portions of the higher level of the rim which are clamped in any
desired position by means of the thumb screw C.
D is the wheel attached to one end of the pivoted lever E the other end of which
actuates the supply tap or valve.
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

page_text: The combination of the revolving disc the rim of adjustable higher and lower
levels, and the pivoted lever with one arm attached to a wheel revolving on the rim
of the disc, and the other arm actuating the gas supply tap or valve substantially as
and for the purposes hereinbefore described.
