PROVISIONAL SPECIFICATION.
Improvements in or connected with Cyclometers and Speed
Indicators.
We, WILLIAM NICKALLS, of 57, Herne Hill Road, Camberwell, in the County of
Surrey, Watchmaker, and ADERITO DA SILVA, of 162, Whittington Road, Bowes
Park, in the County of Middlesex, and 15, Charterhouse Street, in the City of
London, Watch Manufacturer, and Importer, do hereby declare the nature of this
invention to be as follows;-
The invention relates to improvements in or connected with cyclometers and
speed indicators and has for its object in a single instrument to record the distance
travelled and the time occupied in travelling the same and more especially the
time occupied in travelling each recorded mile or part of a mile or other given
distance or number of revolutions.
In carrying the invention into effect a watch or other suitable time keeper is
employed upon the face of which are arranged several small dials indicating for
example in the case of a distance measurer furlongs, miles, tens, hundreds and
thousands, and each of these dials, which is suitably divided is provided with a
hand or pointer and these hands or pointers receive motion from a train of toothed
wheels geared together and so proportioned as to give the requisite movement to
the hands or pointers traversing the counter dials herein before referred to.
The instrument is adapted to be fixed upon the fork of a bicycle or in other
convenient position with relation to the wheel of another form of vehicle and, the
counting train receives motion through suitable intervening mechanism by means
of a star wheel which is acted upon by a tappet device upon one of the spokes or
other part of the wheel once in every revolution thereof.
Upon the face of the time-keeper is also arranged another or time recording or
speed dial which is divided to represent minutes and parts of minutes or other
divisions of time arranged in progressive order whilst adjacent to each time indi-
cation is an indication of distance such indications being arranged in retrogressive
order and this dial is provided with a hand or pointer which is traversed over the
same by the watch movement as hereinafter described.
In order to give motion to the hand or pointer of the time recording or speed
dial a toothed wheel is fitted on the cannon of the centre pinion or first motion
wheel of the watch movement and this wheel engages a pinion fixed with the shaft
of an intermediate or idle wheel which gears with another wheel upon the shaft of
which is loosely mounted a heart shaped cam which is frictionally coupled there
with and the shaft of this heart shaped cam carries the hand or pointer of the
time-recording dial.
In connection with this heart shaped cam is employed a tappet lever unequally
mounted upon an axis of motion and the long arm of this lever engages the heart
shaped cam whilst the short arm thereof is curved and at its end V shaped to
enter the notch or step of a kind of snail or cam wheel fixed upon the toothed
wheel which gives motion to the hand of the furlongs dial of the counter train and
which makes one revolution in one mile.
The tappet lever is acted upon by a spring to hold the short end thereof with
a spring pressure in contact with the snail wheel or cam and the notch or step

page_text: of the snail wheel is so arranged that upon the completion of every mile by the
index hand of the furlongs dial the nose of the short end of the lever will slip
into the notch of the snail wheel or cam and the opposite end of the tappet lever
will strike the heart shaped cam and restore the hand of the time recording or
speed dial to zero.
If desired the watch or other time keeper may be separate from the counting
mechanism and time recording or speed dial and these parts may be provided with
means by the aid of which the counting mechanism may be coupled with the watch
or other time keeper at the times desired so that the latter may be used separately
from the cyclometer mechanism or the time recording and speed mechanism may
form a separate instrument or be combined with a watch movement.
By the means herein before described an instrument is obtained which will clearly
indicate the number of revolutions made or the distance travelled, and the speed
of revolution or travel.
It will be obvious that the instrument may be employed in connection with
vehicles or machines other than bicycles.

Improvements in or connected with Cyclometers and Speed
Indicators.
We, WILLIAM NICKALLS, of 57, Herne Hill Road, Camberwell, in the County of
Surrey, Watchmaker, and ADERITO DA SILVA, of 162, Whittington Road, Bowes
Park, in the County of Middlesex, and 15, Charterhouse Street, in the City of
London, Watch Manufacturer and Importer, 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 improvements in or connected with cyclometers and
speed indicators and has for its object in a single instrument to record the distance
travelled and the time occupied in travelling the same and more especially the
time occupied in travelling each recorded mile or part of a mile or other given
distance or number of revolutions.
In carrying the invention into effect a watch or other suitable time keeper is
employed upon the face of which are arranged several small dials indicating for
example in the case of a distance measurer furlongs, miles, tens, hundreds and
thousands, and each of these dials, which is suitably divided is provided with a
hand or pointer and these hands or pointers receive motion from a train of toothed
wheels geared together and so proportioned as to give the requisite movement to
the hands or pointers traversing the counter dials hereinbefore referred to.
The instrument is adapted to be fixed upon the fork of a bicycle or in other
convenient position with relation to the wheel of another form of vehicle and the
counting train receives motion through suitable intervening mechanism by means
of a star wheel which is acted upon by a tappet device upon one of the spokes or
other part of the wheel once in every revolution thereof.
Upon the face of the time-keeper is also arranged another or time recording or
speed dial which is divided to represent minutes and parts of minutes or other
divisions of time arranged in progressive order whilst adjacent to each time indi-
cation is an indication of distance such indications being arranged in retrogressive
order and this dial is provided with a hand or pointer, which is traversed over the
same by the watch movement as hereinafter described.

page_text: In order to give motion to the hand or pointer of the time recording or speed
dial a toothed wheel is fitted on the shaft of the pinion of the third wheel of the
watch movement and this wheel engages a wheel upon the shaft of which is loosely
mounted a heart shaped cam which is frictionally coupled therewith and the shaft
of this heart shaped cam carries the hand or pointer of the time recording dial.
In connection with this heart shaped cam is employed a tappet lever
mounted upon an axis of motion and the long arm of this lever engages the heart
shaped cam whilst the short arm thereof is curved and at its end ✓ shaped to
enter the notch or step of a kind of snail or cam wheel fixed upon the toothed
wheel which gives motion to the hand of the furlongs dial of the counter train and
which makes one revolution in one mile.
The tappet lever is acted upon by a spring to hold the short end thereof with
a spring pressure in contact with the snail wheel or cam and the notch or step
of the snail wheel is so arranged that upon the completion of every mile by the
index hand of the furlongs dial the nose of the short end of the lever will slip
into the notch of the snail wheel or cam and the opposite end of the tappet lever
will strike the heart shaped cam and restore the hand of the time recording or
speed dial to zero.
If desired the watch or other time keeper may be separate from the counting
mechanism and time recording or speed dial and these parts may be provided with
means by the aid of which the counting mechanism may be coupled with the watch
or other time keeper at the times desired so that the latter may be used separately
from the cyclometer mechanism.
By the means hereinbefore described an instrument is obtained which will clearly
indicate the number of revolutions made, or the distance travelled, and the speed
of revolution or travel.
It will be obvious that the instrument may be employed in connection with
vehicles or machines other than bicycles.
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.

In the several figures in which like parts are indicated by similar letters of
reference, Figures 2 to 6 are drawn to an increased scale with respect to Figure 1
and Figures 7 to 14 are drawn to a still further increased scale.
Referring to Figures 1 to 10 a represents the hub of the steering wheel of a
velocipede a represents the spokes thereof, a² represents the rim or felloe and
a³ represents the fork.

page_text: b represents the case or box which is provided with a cap or lid 61 formed with
an opening 2 therein through which the watch dial hereinafter referred to may be
viewed.
From the box 6 projects a tubular stem 63 which near to its upper end is pro-
vided with a clip band at its lower end is furnished with a bracket 64* which is
perforated to fit upon the axle where it is secured by a nut and by which means
the device may be fixed to the fork a³ of a velocipede as represented at Figure 1
but it will be obvious that the means of fixing the device to the vehicle may be
varied according to the particular kind of vehicle to which it is to be applied..
Within the stem 63 is a shaft 65 which is mounted with capability of rotation in
bearings 65* and at one end of the tubular stem 63 is provided a box 66 within
which and fixed upon the shaft is a worm wheel 67 which gears with a worm 68
fixed upon a short shaft 69 mounted with capability of revolution in a box 10 in
such manner that the worm 68 gears with the worm wheel 67 and upon the end
of the shaft 69 is fixed a star wheel 6 which is adapted to be engaged in the revo-
lution of the wheel of the vehicle by means of a tappet stud c which is by means
of a clamp c¹ fixed with the spokes a¹ of the wheel of the vehicle as shown at
Figure 1 so that at each revolution of the wheel the tappet e engages the star
wheel 611 and moves it one tooth forward.
At its upper end the shaft 65 has fixed therewith the first pinion d of the cyclo-
meter train which consists of a train of reducing gearing d d d and the wheel d²
is frictionally fixed with its shaft d³ which latter at its upper end is provided with
a square * which forms the connection between the reducing train and the
counting mechanism as hereinafter described.
e represents the watch or time-piece, which in addition to the ordinary move-
ment (not shown) and dial e¹ is provided upon its face with several small
dials fffff* representing respectively furlongs, miles, tens, hundreds, and
thousands.
Beneath the several small dials f f f f f are arranged corresponding toothed
wheels g g g g3 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 g* g¹* g²* g3* which gear respec-
tively with the wheels g¹ g² g³g and this train of wheels is so proportioned as to
give the requisite movement to the hands or pointers of the counter dials f f f f³ f*
to give the required indications.
The shaft of an idle wheel h which gears with the wheel g is formed with a
socket adapted to receive the square d* of the shaft d³ of the last of the train
of reducing wheels d d' d² within the cyclometer case b and thus the reducing
train of the cyclometer is coupled with the counting train g g¹g² g³ g of the watch.
Upon the face of the watch e is also arranged another or time-recording or speed
dial which corresponds with the ordinary seconds dial of a watch and which is
divided and figured from 1 to 7 to represent minutes and parts of minutes or they
might be other divisions of time arranged in progressive order with relation to the
traverse of the hand or pointer hereinafter referred to whilst adjacent to each time
indication is an indication of distance the said indications being numbered from 60
to 8.5 in retrogressive order and representing miles per hour and this dial i is pro-
vided with a hand or pointer j* which is traversed over the dial i by the watch
movement as hereinafter described.
In order to give motion to the hand or pointer j* of the time recording or speed
dial a toothed wheel j is fitted on the shaft of the third pinion j¹ of the watch
movement and the pinion ¹ as is well known gears with the centre wheel ** of
the watch movement.
The wheel engages a wheel 2 mounted loosely upon a shaft 3* upon which is
fixed a heart shaped cam 3 and the wheel 2 is frictionally coupled with the cam j³
by means of a spring 2* in the manner well understood, and the shaft 3* of this
heart shaped cam 3 carries the hand or pointer * of the time recording dial i.
In connection with the heart shaped cam j³ is employed a tappet lever k which

page_text: engages the heart shaped cam and is mounted upon an axis of motion k¹ and
this tappet lever k has fixed therewith a short arm or lever which at its end is
curved and formed with a kind of tooth k³ shaped to enter a notch or step of a
kind of snail wheel fixed upon the toothed wheel 9 which gives motion to the
hand or pointer of the furlongs dial f of the counter train and which makes one
revolution in one mile.
The tappet lever k is acted upon by a spring to hold the short end thereof
with a spring pressure in contact with the snail wheel or cam and the notch or
step of the snail wheel is so arranged that upon the completion of every mile
by the index-hand of the furlongs dial f the nose 3 of the short arm of the
lever will slip into the notch of the snail wheel or cam and the opposite
end of the tappet lever will strike the heart shaped cam ³ and restore the
hand of the time recording or speed dial i to zero.
In order to set the counting mechanism back to zero the shaft which gives
motion through the square d* and socket h¹ of the wheel his furnished with a
milled button d' by the aid of which the shaft d³ may be readily turned.
By this arrangement of parts the revolution of the wheal of the vehicle will
correspondingly move the hands of the counter-dials fflfflf whilst at the same
time the watch movement through the wheels will traverse the index hand j*
of the time recording or speed dial i until by reason of the snail wheel or cam
lever and heart shaped cam said hand is restored to zero at the end of
each mile and thus the distance travelled will be permanently recorded upon the
dials f f f f f whilst the rate of travel for each mile or part of a mile may be
easily read off from the dial i.
In this example the watch e is separable from the case 6 and other parts of the
instrument so that it may be carried in the pocket for ordinary use, whilst when
placed within the case b it may be readily coupled with the reducing train of the
instrument by means of the square * of the shaft and the socket h¹ of the
shaft of the wheel has represented at Figure 2.
In the example given at Figure 11 the device is identical with that herein-
before described except that the watch e is supposed to be inseparable under
ordinary circumstances from the case band for this purpose the case b is shaped to
form part of the watch e and the latter is fixed in position by means of set
screws e*.
In the example given at Figures 12 to 14 the device is similar to that herein-
before shown and described with respect to Figures 1 to 10.
In this case, however, the dials f f f f f and the pinion g* toothed
wheels glg g3 g and pinions g₁* * * are removed, by which arrangement the
distance travelled is not recorded but an indication is given of the speed of the
vehicle for each mile or part of a mile travelled.
It will be obvious that the instrument may be employed in connection with
vehicles or machines other than bicycles.
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: --
