Improvements in Cyclometers, Odometers, or Velocimeters.
I, GUSTAVE ADOLPHE SCHOTH of 230 Euston Road in the County of London
Electrical Instrument Maker do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to provide a machine or appliance for indicating
the distance travelled and to be travelled on a known route and as is now partially
done by instruments known as cyclometers, but the invention is also applicable
for counting and registering generally the number of revolutions of shafts or
machinery.
I will describe my invention as applied to a cyclometer; these instruments have
usually been made circular in shape, according to my invention I make them of an
elongated box shape, for example the box might be eight inches long by of an
inch square, but of course I do not limit myself to this size as the same must be
varied according to the purpose to which the instrument is to be applied; for a
cycle or velocipede however and to which the invention is particularly applicable,
I have found the size given to be suitable.
For the above purpose the elongated box contains a fine threaded screw mounted
on pivots in the box ends, the fineness and pitch of the thread of the screw being
regulated according to the distance required to be indicated as hereafter described,
for example if the meter is intended to be capable of indicating a distance travelled
of one hundred miles this screw must be for the same length of twice the fineness
required for indicating fifty miles; or the pitch of the screw should be varied in
accordance with the wheels in gear with same. At one end of the screw there is a
pinion in gear with a worm or worm wheel on a shaft leading down to the wheel, for
communicating motion to the aforesaid screw. Working against the screw and free
to travel by the motion thereof the length of the box there is an indicator which
may be composed of a Y shaped piece of metal, the arms being threaded corre-
sponding with the pitch of the screw and working in same, the leg or tail piece of
the arms passes through a slot to the outside of the aforesaid elongated box and the
said leg carries the index.
A spring, say a flat spring, is or may be applied to the leg of the indicator for
keeping same in position in the thread of the screw, while at the same time it
allows the indicator to be moved along the slot, by simply taking hold of the leg
or tail piece of the same whereby the spring is compressed against the box and the
indicator can then be moved to the position required by the hand. The box cover
may be arranged to take on or off and secured by screws or otherwise. On the
box or box cover I fit a scale which can be easily substituted for another when
required, this scale is marked or graduated in miles or any other measure as required.
so that by changing the scale the apparatus or instrument would indicate the
distance in any measure whether that be miles, kilometres or other scale thus
making the instrument an international or universal indicator, and by changing the
graduations of the scale the instrument is applicable to machines having driving
wheels of different sizes. On the scale and above the graduations I provide a blank.
space for notes so that by marking beforehand with a pencil or a pen the route and
the distances from place to place, it can be ascertained at a glance the position you
are at, the distance you have travelled, and the distance you have to travel. These
positions may be supplemented by other notes, for example the time of arrival at a
place may be marked, and such other notes may be made thereon as may be desired
and thus a complete record of a journey may be obtained and recorded in a book
or otherwise

suitable clamps in which position the scale is at all times visible to the rider. To
machines the spindle is or may be connected to the moving part, the number of the
revolutions of which has to be indicated, by connecting the said spindle thereto in
the ordinary way.

COMPLETE SPECIFICATION.
Improvements in Cyclometers, Odometers, or Velocimeters.
I, GUSTAVE ADOLPHE SCHOTH of 230 Euston Road in the County of London
Electrical Instrument Maker 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 object of my invention is to provide a machine or appliance for indicating
the distance travelled and to be travelled on a known or unknown route and as is
now partially done by instruments known as cyclometers, but the invention is also
applicable for counting and registering generally the number of revolutions of shafts
or machinery.
I will describe my invention as applied to a cyclometer which instruments have
usually been made circular in shape now according to my invention | make them
of an elongated box shape, for example the box might be eight inches long by of
an inch square, but of course I do not limit myself to this size of the box, as the
same must be varied according to the purpose to which the instrument is to be
applied.
In order that my invention may be readily understood I will describe my
apparatus when applied to a velocipede to which machine the invention is par-
ticularly applicable and for which have found a size somewhat as above given to
be suitable.
Figure of the accompanying drawings shows the distance-recording device
constructed according to my aforesaid invention applied to the front wheel and
handle of a "safety" bicycle the front portion of the bicycle only being shown
although it is obvious it might be applied to other parts of the machine.
Figure 2 is a vertical section of the recording box drawn to a larger scale than
shown at Figure 1 to show the interior mechanism, and
Figure 3 is a sectional plan of Figure 2.
Figure 4 is an elevation of the end of the rod which for convenience of space at
Figure 2 is broken off.
Figure 5 is a plan of a toothed or star wheel hereafter described carried at or
near the end of the aforesaid rod.
Figure 6 is a front elevation showing the bearing for the end of the rod.
Figure 7 is a perspective view of a tappet for actuating the star wheel, and
Figure 8 is a detached end elevation of the indicating finger.
For the above purpose the elongated box A contains throughout its length a fine
threaded screw B mounted on pivots or bearings in the box ends the fineness and
pitch of the screw B being regulated according to the distance required to be
indicated as hereafter described; for example if the meter is intended to be capable
of indicating a distance travelled of one hundred miles this screw must be (for the
same length) of twice the fineness required for indicating fifty miles; or the pitch
of the screw should be varied in accordance with the wheels in gear with same.
At one end of the screw B there is a toothed wheel or pinion C in gear with a
worm or screw D, Figure 3, on a rod or shaft E adjustable in length at E', and

page_text: extending down to the velocipede wheel F, for communicating motion to the afore-
said screw D.
Working against the finely threaded screw B, and free to be traversed by the
rotation thereof the length of the box A, there is an indicator G shown detached
at Figure 8, which may be composed of a Y shaped or head piece of metal G, the
interior of the head piece G being threaded corresponding with the pitch of
the screw B, and working against same, the leg or tail piece G³ proceeding from
the head G, passes through a slot (extending the length of the box B and shown
in dotted lines at Figure 2) to the outside of the aforesaid said elongated box A,
and the said leg G2 carries the index or indicator finger G. A spring (3 of flat or
spiral form is or may be applied to the leg G of the indicator, for keeping same
in position in the thread of the screw B, while at the same time it allows the
indicator G to be moved along the slot by simply taking hold of the leg or tail
piece G² of the same, whereby the spring 3 is compressed against the box A, and
the indicator can then be moved to the position required by the hand. On the
indicator arriving near the end of the screw and indicating say for example,
100 miles, the indicator ceases acting by reason of the screw B being reduced in
diameter at B', so that on the arrival of the head Gat this part its traversing
motion ceases as aforesaid. The box cover A' may be arranged to take on or off
and be secured by screws or otherwise.
On the box or box cover 1 fit a scale A2, preferably of xylonite, which can be
easily substituted for another when required. This scale is marked or graduated in
miles or any other measure as required, so that by changing the scale the
apparatus or instrument would indicate the distance in any measure whether that
be miles, kilometres or other scale, thus making the instrument an international or
universal indicator, and by changing the graduations of the scale or the gearing of
the worm screw, the instrument is applicable to machines having driving wheels of
different sizes. On the scale and above the graduations I provide a blank space
for notes, so that by marking beforehand with a pencil or pen the route and the
distances from place to place, it can be ascertained at a glance the position you are
at on the road, the distance you have travelled, and the distance you have to
travel these positions may be supplemented by other notes, for example the time
of arrival at a place may be marked and such other notes may be made thereon as
may be desired and thus a complete record of a journey may be obtained, and
recorded afterwards in a book or otherwise.
As applied to a cycle the instrument should be affixed to the handle bar Hor
other part by suitable clamp J in which position the scale is at all times visible to
the rider, the clamp J is shown as being adjustable by the segment slot, so that the
position of the box A may be set according to circumstances; the lower end of the
rod or shaft E is supported in an adjustable step bearing K, shown detached at
Figure 6, the rod or shaft E being provided with a tooth or star wheel L, Figures 4
and 5, formed preferably of india rubber or like elastic material. M is a tappet
Figures 1 and 7 which at every revolution of the running wheel revolves the star
wheel L through the space of one tooth. To other machines the spindle is or may
be connected to the moving part, the number of the revolutions of which has to be
indicated, by connecting the said spindle thereto in any ordinary way or convenient
manner.
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. In cyclometers, odometers and velocimeters, the use and employment therefor
of an elongated box having an index thereon and an index finger traversed length-
wise of the box by a screw rotated by gearing from the moving part of the machine
all substantially as and for the purposes herein set forth.
2. In cycloneters, odometers, and velocimeters, the box A A' with index A²,

page_text: indicator G, screw B, pinion or wheel C, worm.D and actuating, rod or shaft E all
substantially as and for the purposes herein set forth.
3. In cyclometers, odometers and. velocimeters the combination with the box and
index AA A2 and the rotated screw B of the indicator having head G³, tail
piece G, index finger G and spring G³ substantially as and for the purposes shown
and described.
4. The combination with apparatus as claimed in Claim 2, of a clamp J for
securing the apparatus to the velocipede and the bearing K rubber star wheel L
and tappet Mall substantially as and for the purposes described and shown with
reference to the accompanying drawings.
Dated this on way or June 1OUT.
