Improvements in Cyclometers and Speed Indicators for Velocipedes
and other Vehicles.
ALEXANDER NICHOLSON, 29, Mary Street, Dublin, Cycle Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention consists of improvements in cyclometers and speed indicators for
velocipedes and other vehicles, and has for its object to enable the rider to read
the figures while travelling and without dismounting or leaving the seat.
In carrying out my invention, instead of the usual glass at present used over
the dial or figures I use a suitable lens or magnifier of sufficient power to enable
the rider to easily read the figures while travelling at the ordinary speed.
I can also fix the lens by a suitable holder or mounting according to the size
or make of the instrument so that it can be applied to existing instruments as
well as new ones.

Improvements in Cyclometers and Speed Indicators for Velocipedes
and other Vehicles.
ALEXANDER NICHOLSON, 29, Mary Street, Dublin, 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 cyclometers, and speed indicators hereinafter called
the indicator used in connection with cycles, motor or other vehicles. Usually
the indicators are fixed so distant from the driver or passenger that the figures
or indications cannot be conveniently seen especially when the cycle or vehicle is
in motion. The object of my invention is to enable the person to read the indi-
cator without inconvenience or dismounting and consists in arranging or fixing
a sufficiently powerful magnifying-glass or lens in combination with the indicator.
Or the lens is carried by a suitable holder, or mounting so that it can be attached
to or near the indicator as required.
In carrying my invention into effect I replace the usual plain glass over the
face or dial with a lens, or fix a lens outside the glass, either way preferably some
distance away from the face of the indicator so as to give scope for the lens to
act over the whole face of the instrument. The holder or mount carrying the
lens is preferably made of some light transparent material such as celluloid or
xylonite, and can be part of the instrument itself or preferably made so as to
ID 77

page_text: be easily detachable and can be fixed to the indicator or part of the machine as
required according to the size and shape of the indicator. Obviously the size
shape and magnifying power of the lens, as well as the shape, material, and plan
of attachment of the holder can be modified to suit the various indicators.
In the accompanying drawings is illustrated my invention as applied to a
cyclometer of the well known Veeder class, in which A shows the cyclometer,
B the lens, and C the holder made of celluloid tube and transparent so as to
admit the light through on to the figures. The upper portion is formed with a
groove to hold the lens and the lower end moulded to tightly clasp the cyclometer
but shown some distance open in the drawing for clearness.
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. A mount or holder made of transparent celluloid, xylonite, or other suitable
material carrying a magnifying-glass or lens, and adopted for fixing to or in con-
nection with the indicator substantially as herein before described and set forth
with reference to the drawing.
2. The improvements substantially as herein before described and set forth.
3. For indicators as herein before described the combination of such indicator
and a magnifying-glass or lens for the purpose specified.
