Improvement in connection with Cyclometers.
Year: 1898

page_text: JOHN NICHOLAS KNOTTESFORD-FORTESCUE, 26, Grafton Square, Clapham, London,
Engineering Student, do hereby declare the nature of this invention to be
as follows:-
The invention consists in fastening cyclometers on to the wheel of a bicycle
or tricycle and the catch for operating the cyclometer on to the fork, instead
of the present method of fastening the cyclometer on to the fork & the catch
on to the wheel.
The advantage is that the cyclometer being within and between the spokes of
the wheel is safe from being knocked about, especially travelling by train.
One way in which my invention can be carried out is as follows. I fix a
plate on to the cyclometer and arrange it so that it may be attached to the
spokes of the wheel by one or more screws, passing in the space between the
spokes and secured to another plate; but it will be understood that the particular
method of attachment may be altered without departing from the essential
feature of my invention, which consists in the attachment, so that the cyclometer
is protected by being placed within the spokes of the wheel.
This invention can be applied to almost any cyclometer, and by its means
cyclometers may be attached to any vehicle.

Improvement in connection with Cyclometers.
JOHN NICHOLAS KNOTTESFORD-FORTESCUE, The Residence, British Museum,
London, W.C., Engineering Student, Late of 26, Grafton Square, Clapham,
London 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:-
The invention consists in fastening cyclometers, on to the wheel of a bicycle
or tricycle and the catch for operating the cyclometer on to the fork, instead
of the present method of fastening the cyclometer on to the fork & the catch
onto the wheel.
The advantage is that the cyclometer being within and between the spokes of
the wheel is safe from being knocked about, especially travelling by train.
One way in which my invention can be carried out is as follows. I fix a

page_text: plate on to the cyclometer and arrange it so that it may be attached to the
spokes of the wheel by one or more screws passing in the spaces between the
spokes and secured to another plate.
But it will be understood that the particular method of attachment may be
varied without departing from the essential feature of my invention, which
consists in the attachment, so that the cyclometer is protected by being placed
within the spokes of the wheel.
This invention can be applied to almost any cyclometer, and by its means
cyclometers may be attached to any vehicle.
In order that the invention may be more fully understood, I have illustrated
it by the accompanying drawings, which show the means I use to fix the
cyclometer by placing it within and between the spokes of the wheel, & the
catch which operates it to the fork.
Figure 1 shows a side elevation.
Figure 2 shows an end view.
I proceed thus to fasten the cyclometer on and between the spokes of the
wheel.
First place the cyclometer (with the ordinary stand B) tangent to one of the
spokes. Arrange the stand B, so that it shall have two spokes over it and
two spokes under it.
Take the plate A, which is of very thin material, & place it between the
stand B, and one of the outer spokes (marked S).
Next take plate C, which has one grove in it, & is partly roughed, as a pre-
caution against slipping.
Place plate C at the back, on the inside of the wheel, so that one of the spokes
shall be in the grove. Pass the screw E through the holes in plates A and C,
& screw up.
It will now be found that the cyclometer is firmly and safely fastened.
Now to arrange the operating catch, slack the nut N, shown in Figure 2. Take
the plate D and place it either between the fork and the wheel, or between the
nut and the fork which ever is most convenient.
The gap G allows one to do this without taking the nut off.
Arrange D, so that the cyclometer moves round with the wheel, so that the
trip may just touch one of the teeth of the cogwheel at each revolution of the
wheel. When this is arranged tighten the nut N.
The whole of this operation can be done in a very few minutes.
In case there is not sufficient room to allow the cogwheel of the cyclometer
to pass the fork, I insert a washer or so on both sides of the wheel, as shown
by the letter I in Figure 2.
In Figures 1 and 2, I have shown another arrangement for carrying the catch
or trip (D and F¹), which could also be used. This would slip over the fork
& then tightened by a screw, very much in the same way as a foot rest is
fastened on to the fork. By this means the trip for operating the cyclometer
would be entirely concealed.
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) The method of fixing a cyclometer to the wheel and actuating it by a trip
or catch attached to the fork or frame of the velocipede or other vehicle sub-
stantially as herein before described.
2) The method of fixing a cyclometer within the spokes of a wheel, and so
that it is protected thereby, and actuating it by means of a trip or catch attached
to a non-revolving part of the velocipede or vehicle substantially as herein-
before described for this purpose.
3) A device for fixing a cyclometer to the spokes of a wheel substantially as
described and illustrated.

page_text: 4) A device for fixing a trip or catch to the fork of a velocipede or other
non-revolving part of a vehicle in order, that it may actuate a cyclometer, which
is attached to and revolves with a wheel, substantially as described and illustrated.
