Improvements.in.or relating to Cyclometers.
We, ALFRED DIETZE, Merchant and WILHELM DANNEHL, Iron Turner :both of
Kirchgasse, Leisnig in the Empire of Germany, 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 a cyclometer which by means of the entire movement
or working part indicates each meter travelled up to 10,000 kilometers in successive
numbers in such a manner that one has only to read them of to ascertain the distance
traversed.
.
It indicates also the time taken for the distance 'travelled.
It has the advantage for measuring the 'longest distances quickly and exactly and
is intended for military racing and touring purposes.
This cyclometer consists of a driving device and an indicator.
In the annexed drawing-
Fig. 1 is an elevation froin the right hand side of the driving device.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is a plan view of the registering apparatus.
Fig. 4 is the front view of the cyclometer.
Fig. 5 is the side view of 'Fig. 4 as seen from the right.
Fig. 6 is the side view of Fig. 3 as seen from the left.
Fig. 7-is a cross-section on the line of Fig. 3.
Fig. 8 shows the right and left side views of a number roller.
Fig. 9 shows a cross-section on the line ww of Fig. 8.
As shown in Fig. 1 the driving device is fixed by means of the screws a, a, a on
the right side of the cycle fork.
The lever bis movable on the pivot b¹ and secured by means of the nut b².
The pin b is fixed in the clamp c.
The lever bis guided by the bow c¹ and is fixed higher or lower in the slot c³ by
means of set screw c², which is screwed in the lever.
The lever b, Fig. 2 is bent at the top and at the right the arm b³ is screwed on to
the lever b.
Between the arm 63 and the end of the lever b Fig. 2 the-axle-d revolves on steel
points respectively fixed on the arm-and the lever.
On the revolving shaft d there is fixed the india rubber roller d¹ and the grooved
pulley.d².
When the lever is let down until the rubber roller touches the tyre of the
front cycle wheel, the movement of the latter is transferred to the roller d¹.
The counting device is shown in Fig. 3.
On the shafte between .the,holders f.and g, there-is fixed on the outside of the
case which contains the registering movement the grooved pulley e¹ and on the
inside the small toothed wheel e².
The toothed wheel e2.gears with the toothed wheel h.

page_text: The toothed wheel h by means of the attached small toothed wheel h¹ gears with
the toothed wheel which by means of the attached toothed wheel ¹ gears with
the toothed wheels attached to the roller q which records the units.
From the roller q all the other number rollers are put into movement by means
of the carrying toothed wheels llllll.
These toothed wheels are movable on the long shaft m which is held movably at
its right hand end in the holder g and at its left hand end in the side of the casing
by means of screw nuts.
Between each two of the toothed wheels there is arranged on the shaft ma
ring n and a spiral ring o.
These rings are fixed on the shaft by means of set screws in order that each
toothed wheel may move independently.
On the inner side of the left side of the casing there is fixed a ratchet wheel p on
the shaft m, into which the pawl spring preaches which is fixed on the side of the
casing. On the outside of the casing there is fixed a crank p² on the shaft m.
Each number roller has the following numbers 1 2 3 4 5 6 7 8 9 0.
Each roller from the right during one revolution turns the roller on its left
hand 1/10 of a revolution by means of the pin q' on the roller q Fig. 8 which once
in every revolution turns the wheel one tooth further and this movement
is transferred to the next roller because the toothed wheels gear with toothed
wheels attached to the recording rollers.
The rollers are stamped out of thin plate and formed into the shape of a drum
Fig. 9 and on the right side there are soldered spur wheels 8, Fig. 8 and on the
other side a boss t and a pin q¹.
These rollers turn on the rod u which connects the sides of the casing.
This mechanism is provided with a casing g², Fig. 4.
The front the covering has a slot so that the row of the numbers can be seen. This
slot is covered with glass.
The springs are arranged on the upper part of the inner side of the
front of the casing.
By turning the crank p² Figs. 3 and 4 the toothed wheels can be moved so far
by the spring tension of springs o and the rollers 9 9 9 9 9 9 engaging therewith
until the springs rrrrr fixed on the inside of the top of the casing Fig. 7
engage into the grooves 71 Fig. 8 of the number rollers. They are thus returned
to zero.
As soon as the crank p2 Fig. 6 is turned in the direction of the arrow the number
rollers are moved so far until all the zeros marked on them are visible, through the
slot provided in the casing exception of the roller for the units which is set by
turning the grooved pulley e¹.
The grooved pulleys e¹ and d² are connected by means of a string in the form of
an endless band.
On the apparatus is screwed a holder for a watch which by loosening the screws
can be taken off.
At the under part of the apparatus two vertical arms are fixed provided with grips
actuated by set screws in order to fasten the apparatus on the handle bars of the
cycle.
It will be easily seen from the above description and accompanying drawings that
the movement of the front wheel of the cycle actuates the india rubber wheel d¹
which by means of the grooved pulley d² and the endless string communicates
movement to the pulley e¹ which operates the working of the recording mechanism
as described so as to show each meter travelled up to a distance of 10,000 kilometers
and the distance can be read without dismounting from or stopping the cycle.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we claim is―
1. A cyclometer, which by means of its construction indicates the movement of
the exterior border of the front wheel in meters in successive numbers and indicates

page_text: also the time required occupied in traversing the distance substantially in the
manner and by the construction herein described.
2. A cyclometer constructed in the manner described and illustrated for showing
the distance traversed by the periphery of the front cycle wheel and having on it a
watch holder as set forth.
