Improvements in Dials or Indicators for Denoting the Times for
Lighting up the Lamps of Bicycles and other Road Vehicles.
I, WILLIAM FREDERICK MARTIN, of Ringmer, near Lewes, in the County of
Sussex, Engineer and Builder, do hereby declare the nature of this invention
to be as follows:-

In order to conform to statutory or other regulations, lamps carried by bicycles,
carriages, carts, wagons, cars, and the like, must be lighted at definite hours, which
are dependant upon the varying times that the sun sets during the year.
In country places and sparsely inhabited districts some difficulty is oftentimes
experienced in obtaining information as to the proper time for lighting-up.
Now my invention consists in constructing a dial

The dial may be constructed of metal or other suitable material, and of con-

The wording or lettering and figures may be embossed, inscribed, or otherwise
suitably formed thereon.

Improvements in Dials or Indicators for Denoting the Times for
Lighting up the Lamps of Bicycles and other Road Vehicles.
I, WILLIAM FREDERICK MARTIN, of Ringmer, near Lewes, in the County of
Sussex, Engineer and Builder, 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:―
In order to conform to statutory or other similar regulations, lamps carried by
bicycles, carriages, carts, cars, wagons, and the like, must be lighted at definite
hours, which are dependent upon the varying times that the sun sets during the
year.
In country places and sparsely inhabited districts some difficulty is oftentimes
experienced in obtaining information as to the proper time for lighting-up.
Now my invention consists in constructing a dial upon the face or sides of which
various dates in the year are placed, and opposite to such dates, the proper times
for lighting-up.

page_text: The dial may be constructed of metal or of other suitable material, and of a con-
venient shape and size, as for instance, for either carrying in the pocket or affix-
ing to a vehicle. The wording, lettering, or figuring, on the dial may be embossed,
inscribed, or otherwise suitably formed thereon.
Now in order that my invention may be the more particularly described and
ascertained I have appended a sheet upon which one form of my indicator is illus-
trated, in size suitable for attachment to a vehicle by a central screw.
As will be seen in this example, there is placed upon the inner circle A the
months of the year, enclosing this circle there is another circle B which contains
days of the month, and against these days there is shewn on the outer circle C the
time on any particular day that the lamps carried by bicycles or, other road vehicles
must be lighted.
For instance, if lamps must be lighted one hour after sunset, on reference to the
indicator which is divided up according to this rule, it appears that on January
the 13th the lamps must be lighted at a quarter past five o'clock, and so on for
other dates.
In parts of the country as for instance in Ireland where there is a striking differ-
ence between Greenwich and local time, the indicator would be correspondingly
graduated for use in that locality.
Although I have shewn a circular disc with a particular set of indications upon
it I would have it understood that I do not confine myself to that particular form
or set of indications, as I may vary both according as may be desirable.
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:
A disc, plate, cover, or the like, upon which certain times are placed against
or in proximity to particular days of the month, substantially as and for the pur-
pose hereinbefore described and illustrated in the accompanying drawing.
Dated this 1st day of June 1898.
WILLIAM FREDERICK MARTIN.
