TAYLOR DALRYMPLE WILSON (Gentleman) Pound Farm, Chawton, Alton, Hants
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to render the figures on dials of distance or speed
indicators of velocipedes, and other wheeled vehicles more easily read by the rider,
for this purpose, I fix or attach a magnifying glass near to or at a suitable distance
from, the indicator, so that the numbers on the dial will appear magnified, and may
be easily read by the rider, or driver, without dismounting. The magnifying glass
may be attached by any suitable means to any suitable part of the velocipede or
other wheeled vehicles, or to the indicator, and such magnifying glass may be
adjustable in every necessary direction for obtaining the proper focus and line of
sight.

An Improvement relating to Speed Indicators and Cyclometers for
Velocipedes and other Vehicles.
I, TAYLOR DALRYMPLE WILSON (Gentleman) formerly of Pound Farm, Chawton,
Alton, Hants, and now of 71, Philbeach Gardens, Earl's Court, London, S.W., 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 :-
My invention has for object to enable a cyclist or the driver of a motor vehicle to
read off a cyclometer or distance or speed indicator at a glance whilst travelling.
The instrument to be read off is mounted in the usual position and operated in
the usual way by one of the wheels of the cycle or other vehicle and the Invention
consists in the combination with the instrument to be read of a magnifying lens
suitably mounted in such position as to enable the magnified image of the figures to
be more clearly legible whilst travelling.
The accompanying drawings illustrate in Figures 1 to 5 one mode of mounting the
lens as applied to a bicycle, Figure 1 being a side view of part of the steering fork
and Figures 2 3 4 5 detail views of the adjustably mounted lens and its support.
C is the cyclometer or indicator of any ordinary kind, L is the magnifying lens
carried by an arm I mounted adjustably on the fork F so as to enable the lens to be

page_text: adjusted both to and fro and up and down to the proper focal distance from the
instrument to be read and in the direct line of vision of the rider. For this purpose
the arm is slotted at and secured by a clamping screw b to a band B clipped
around the member of the fork, the hand being secured on the fork by the same
screw band by a nut b¹ at back.
Figure 6 is a perspective view of the cyclometer separately and Figure 7 is a
perspective view of a modified means of supporting the lens L which in this instance
is hinged or otherwise attached to the upper end of an arm adjustably connected
to a cylindrical cap A adapted to fit on the cyclometer shewn in Figures 1 and 6 and
having a peripheral aperture at which the figures are visible, the cap being circularly
adjustable upon the cyclometer and the arm being held in guides a a on the end
of the cap and engaged by a spring pawl al on the one guide engaging in rack teeth
on the arm so as to enable the lens to be adjusted for focus and line of sight.
Figure 8 shews a dial form of cyclometer and Figure 9 a perspective view of a
mode of mounting the lens thereon, A in this case being a spring collar or band
adapted to clip the cyclometer circumferentially, the rack supporting arm and its
means of adjustment being otherwise the same as in Figure 7.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The combination, with a cyclometer or distance or speed indicator for cycles and
other vehicles, of a magnifying lens adjustably mounted in such relation thereto as to
admit of the indications being read off from a distance as described.
