Year: 1897

page_text: We, WILLIAM HENRY KEMBER and ADERITO DA SILVA, of 15, Charterhouse
Street, London, E.C., Watch Manufacturers and Importers (trading together under
the style of Kember, Silva & Co.), do hereby declare the nature of this invention
to be as follows:-
Namely an instrument combining a time piece and a distance recorder showing
upon a dial any distance travelled up to twelve thousand miles and the time
taken to cover such distance. It can be used as a watch to wear or in conjunction
with the cyclometre and can be adapted to cycles, cabs, motor cars, railway engines
and all vehicles where it is desirable to know the rate of speed, time taken and
distance travelled. The instrument consists practically of a watch with a double
set of dials in one plate one being the ordinary watch dial and the other for the
cyclometre with five independent hands and discs, the 1st marking one mile, the
2nd ten miles, the third one hundred, the 4th one thousand and the 5th twelve
thousand the cyclometre taking its motive power from the cycle wheel by an
action near the hub of the front wheel by means of a star & roller pin attached
to the spoke. A brass cylinder with a shaft inside runs up the side of the fork
& is attached to it by a clip. The top of the shaft has a train of wheels and pinions
forming a connection with the watch motion work under the dial, the whole being.
affixed to the handle bar and the like.
An Improvement on Watches and Cyclometers Combined.
We, WILLIAM HENRY KEMBER and ADERITO DA SILVA, of 15, Charterhouse
Street, in the City of London, Watch Manufacturers and Importers, 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 relates to an improvement on watches and cyclometers combined
and the object thereof is to obtain a combined time piece and distance recorder
which will indicate upon a dial the distance travelled up to, for example, twelve
thousand miles and the time occupied in travelling such distance and in which
D

page_text: the time piece may be readily separated from the main parts of the distance
recorder and carried in the pocket as an ordinary watch and the cyclometer may
be employed separately therefrom if desired.
In carrying the invention into effect a case or box is employed from which
projects a tubular stem which is adapted to be fixed, for example to the fork of a
velocipede by means of a clip and within this stem is a shaft at one end of which
is a star wheel which is adapted to be engaged in the revolution of the wheel of
the vehicle by means of a roller tappet which at each revolution of the wheel of the
vehicle moves the star wheel one tooth forward, whilst the overdriving of the
shaft is prevented by means of a spring detent which engages a notched or toothed
wheel carried by the shaft.
At its other end the shaft gives motion through a coupling to a short shaft upon
which is fixed a pinion which gives motion to a train of reducing gearing arranged
within the box or case and the last wheel of which is provided with a square
spindle.
The watch or time piece in addition to the ordinary movement and dial is
provided upon its face with several small dials indicating units, tens, hundreds,
thousands and tens of thousands, and beneath each of these small dials is arranged
a toothed wheel, and these several wheels are geared together and so proportioned
as to give the requisite movement .to hands or pointers fixed with the shafts or
spindles thereof and traversing the counter dials hereinbefore referred to.
An idle wheel gearing with the unit wheel is formed with a socket adapted to
receive the square of the last of the train of the wheels within the cyclometer
case, and thus the reducing train of the cyclometer is coupled with the counting
train of the watch.
The watch is enclosed within the case of the cyclometer by means of a tightly
fitting cap which is adapted to exclude dust and moisture.
By this arrangement of parts the revolution of the wheel of the vehicle will
correspondingly move the hands of the counter dials, and inasmuch as these are
arranged upon the dial of the watch or time picce it will be easy to read off the
distance travelled and the time occupied.
A simple device of the ordinary character is employed to return the hands of the
counting mechanism to zero when required.
When it is desired to employ the cyclometer alone without the time piece a set
of counter dials and train of wheels similar to that carried by the watch or time-
piece and adapted to engage the spindle of the reducing gear in the same manner
are mounted on a loose plate or fitting adapted to drop into the case of the cyclo-
meter so that the cyclometer may be used by itself or in combination with the
watch or time piece at will.
It will be obvious that the device may be adapted to all kinds of vehicles such
as velocipedes, cabs, motor cars, railway engines and other vehicles.
And in order that the said invention may be more clearly understood and readily
carried into effect we will proceed, aided by the accompanying drawings, more
fully to describe the same.

Figure 9 is a face view of the watch or time piece separately.
Figure 10 is a similar view but with the dial removed and
Figure 11 is a vertical section of a portion of a cyclometer illustrating a

In the several figures in which like parts are indicated by similar letters of
reference Figures to 11 are drawn to an increased scale with respect to the other
figures of the drawings.
Referring to Figures 1 to 10 a represents the hub of the steering wheel and a¹
represents the spokes thereof, 6 represents a case or box which is provided with a
cap or lid 6 fitted with a disc of glass or other transparent material 63.
From the box b projects a tubular stem 63, which is provided with a clip b
by the aid of which it may be fixed for example to the fork a³ of a velocipede as
represented at Figure 1, but it will be obvious that the means of fixing the device
in position will vary according to the particular kind of vehicle to which it is to
be applied.
Within the stem 63 is a shaft bo which is mounted with capability of rotation in
bearings 65 and at one end of the shaft 65 is fixed a star wheel 60 which is adapted
to be engaged in the revolution of the wheel of the vehicle by means of a roller
tappet carried in a bifurcated holder c clamped upon one of the spokes a¹ of the
wheel of the vehicle by means of a screw ca as shown more particularly at Figure 2,
and this roller tappet cat each revolution of the wheel a engages the star
wheel 166 and moves it one tooth forward whilst the over-driving of the shaft b
is prevented by means of a spring detent 67 which passes through a slot or open-
ing 6* in the stem 73 and engages a wheel 68 fixed with the shaft b and notched
to correspond with the star wheel 66.
The notched wheel 68 by its boss engages the end cap of the stem 63 and prevents
the endway movement of the shaft 65 in one direction, whilst a collar 6° fixed with
the shaft 65 upon the exterior of the stem by means of a set screw or otherwise
prevents such movement in the opposite direction.
At its other end the shaft 65 gives motion to the first pinion of the cyclometer
train through a coupling consisting of a short cylinder 610 formed with slots b
therein which engages a cross bar or pin d¹ carried by a boss de fixed with a short
shaft or spindle upon which is fixed a pinion d³.
The coupling connection herein before described to some extent prevents the
transmission of shocks or vibrations to the mechanism inasmuch as the continuity
of the shaft is broken or interrupted.
The pinion d³ gives motion through a train of reducing gearing consisting of
wheels and pinions d' d d d d to a cannon wheel do which is by its cannon fric-
tionally fixed with a shaft e at its upper end provided with a square el which forms
the connection between the reducing train and the counting mechanism as herein-
after described.
f represents the watch or time piece, which in addition to the ordinary move-
ment (not shown) and dial f¹ is provided upon its face with several small
dials f f f f f representing respectively units, tens, hundreds, thousands, and
tens of thousands, and the latter dial for convenience is numbered up to twelve
thousand.
Beneath the several small dials f f f f f are arranged corresponding toothed
wheels g g g g5 g and the hands or pointers of the counter dials are fixed upon
the shafts or axes thereof.
The several wheels are furnished with pinions 9** 93* 9** 95* which gear re-
spectively with the wheels g³ ³ 96 and the teeth of the train of wheels are so
proportioned as to give the requisite movement to the hands or pointers of the
counter dials f f f f f at one tenth part of the speed of the preceding one and

page_text: thus to give the required indications in units, tens, hundreds, thousands and tens
of thousands.
The shaft of an idle wheel g¹ which gears with the unit wheel 92 is formed
with a socket g* adapted to receive the square e¹ of the last of the train of
wheels dddd within the cyclometer case 6 and thus the reducing train of
the cyclometer is coupled with the counting train g³ 9³ gʻ 95 96 of the watch.
The watch is enclosed within the case b of the cyclometer by means of the
cap which tightly fits the case b and thus excludes dust and moisture whilst in
order to admit of the passage of the stem f* of the watch f the case band lid b¹
are notched to embrace the same as shown more particularly at Figures 1 and 3.
The watch is fixed within the case b and caused always to assume a given
position therein so as to register with the square e¹ of the reducing train by means
of a V pointed set screw * which engages a corresponding recess in the watch
case,
When it is desired to use the watch separately from the cyclometer the aperture
in the case through which the square e¹ of the spindle e passes to engage the
socket g✶ of the wheel g₁ is closed by means of a sliding cover g³ turning upon
a centre of motion 99*.
In order to set the counting mechanism back to zero the shaft e which gives
motion through the square e¹ to the idle wheel g¹ is furnished with a milled button
head by the aid of which the shaft e may be readily turned.
By this arrangement of parts the revolution of the wheel a of the vehicle will
correspondingly move the hands of the counter dials f f f f5 fo and inasmuch
as these are arranged upon the dial of the watch or time piece f it will be easy
to read off the distance travelled and the time occupied.
By modifying the number of teeth of the toothed wheel g¹ according to circum-
stances, the instrument may be adapted to road wheels of varying diameter.
Although the roller tappet c¹ is shown affixed to the wheel of the vehicle near to
the hub thereof it will be evident that it may sometimes be desirable to place it
near the rim or felloe in order that the instrument may be fixed upon the fork a²
in a position nearer to the rider and more convenient for reading off the indi-
cations.
In the example given at Figure 11 which represents a vertical section of a
portion of a cyclometer constructed according to the present invention a set of
counter dials and co-acting parts identical with those combined with the watch
in the previous figures are mounted in a separate case f similar to a watch case
which is adapted to drop into the case 6 where it is removeably held in a similar
manner to that herein before shown and described with respect to the watch.
By this arrangement of parts the cyclometer may either be used without the
time piece or the case f and parts carried thereby may be removed from the case b
of the cyclometer and the watch may be substituted therefor in the manner shown
in the previous figures.
Although the invention is herein before shown and described in connection with
a velocipede it will be obvious that it is equally applicable to all kinds of vehicles
such as cabs, motor cars, railway engines or the like or to the propeller shaft or
other rotating part of a marine or other engine or the like and although the
stem 63 of the case 6 forms a convenient means for fixing the device in position
and enclosing the shaft 5 it will be understood that such shaft may be shortened
and the stem wholly or partly dispensed with whilst the case may be fixed to
the vehicle in any other suitable manner.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what we
claim is :-
1. The combination of a cyclometer or distance or revolution measurer and a
time niece or watch the cyclometer and watch being so combined as to be easily

page_text: separable so that the watch may be used separately from the cyclometer sub-
stantially as herein shown and described.
2. The combination of a cyclometer or distance or revolution measurer provided
with a case and a time piece or watch adapted to fit into the case the cyclometer
being fitted with a train of reducing wheels and the watch with a train of counting
wheels and counter dials and means for coupling the two trains upon the intro-
duction of the watch into the cyclometer case, substantially as herein shown and
described.
3. The combination of a cyclometer provided with a case adapted to receive a
watch, a train of reducing wheels within the case, a shaft for giving motion to the
train, a star wheel upon the end of the shaft for engaging a projection on the
wheel of the vehicle, and a square or the like on the spindle of the last of the train
of wheels and a watch or time piece adapted to fit the case and provided with
a train of counting wheels and corresponding counter dials and a square socket or
the like on the spindle of the first of the train of wheels adapted to engage the
co-acting part on the last of the train of wheels of the cyclometer substantially as
herein shown and described.
4. The combination with a cyclometer of a train of reducing wheels, means for
driving the same from the wheel of a vehicle a removeable part furnished with a
train of reducing wheels and counter dials and means for automatically coupling
the train of the removeable part with the reducing train of the other part sub-
stantially as herein shown and described.
5. The combination with a watch or time piece of a train of counting wheels,
corresponding counter dials arranged upon the ordinary dial and means for
coupling the counting train with suitable driving means substantially as herein
shown and described.
6. The general construction, combination and arrangement of parts substantially
as herein shown and described.
