COMPLETE SPECIFICATION.
A Combined Cyclometer and Speed Indicator.
I, WILLIAM SOULE SCALES, of No. 19, Norwood Street, Everett, in the County
of Middlesex, State of Massachusetts, United States of America, Mechanic, 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 has relation to mechanisms for indicating the rate of speed at
which a moving part, such as a vehicle wheel, or a shaft is rotated, and has for its
object to provide such improvements in the same that the movement of the
moving part will be transmitted to the indicating devices without the employment
of a rotating governor and its consequent disadvantages, and through the medium
of an intermittently acting device such as is ordinarily employed in cyclometers.
The invention consists of a speed indicator equipped with those features of con-
struction and arrangement, which are illustrated on the drawings, and now to be
described in detail and set forth in the claims hereto annexed.
Reference is to be had to the accompanying drawings and to the letters and
figures marked thereon, forming a part of this specification, the same letters desig-
nating the same parts or features, as the case may be, wherever they occur.

page_text: Figs. 13 and 14 represent portions of the indicator mechanism.
In carrying out the invention, I may embody it in forms of various kinds, and
hence it will be understood that while I have illustrated the best form now known
to me,
I am not limited to the details of construction thereof, and may vary them
as occasion or necessity dictates.
Referring to the drawings,-a indicates a cylindrical case, having the base a¹
and the cap a² equipped with the glass disk a³ through which the dial a Fig. 2
may be observed. The case is secured upon the spindle b of a bicycle wheel hub b',
between the fork bar 62 and the nut 63 by a bar bent at right angles and having
the laterally extended slotted arm, through which extends a nutted bolt 6 secured
upon a bent standard 66 attached by screws to the said base a¹. By loosening the
bolt 65, the instrument may be adjusted towards or from the wheel, after which
it is readily secured in the desired position.
The base a¹ is formed or provided with a downwardly projecting boss a³ which
furnishes the lower bearing for the main arbor e from which power is transmitted
to the speed indicator and the distance registering mechanisms. The arbor c is
squared at its lower end (not shown) to extend into a square aperture in a star
wheel c', the latter being secured in place by a screw entering a threaded
aperture in the arbor. A washer of leather or other suitable material is inter-
posed between the boss or bearing and the wheel to furnish sufficient friction for
preventing the latter from rotating too freely. The said star wheel is rotated with
a step-by-step movement, by a clip clamped or otherwise secured upon the
spokes 68 of the bicycle wheel, and which strikes a tooth at cach revolution of
the said wheel.
Resting upon posts d, d¹, d³, projecting upward from the base al is a plate or
disk d³ Fig. 12, upon which the cyclometer movement is mounted, and through
which the arbor c extends, the indicator mechanism being arranged between the
base a¹ and the plate d³.
Secured upon the arbor c is a cam e having three leaves, and pivoted at f¹ is
a lever designated as a whole by f. The latter has an arm fl which projects
across the base a¹ and is laterally extended at f to receive two pins f³ f which
project downward on both sides of the cam e Fig. 3, it also having a slot f5 to
receive the arbor c. The star wheel el has six teeth or leaves, and the cam has but
three, so that when the said star wheel has made one revolution, the lever f will
have been reciprocated three times by the cam e striking against the pins f³ f
(that is the lever will have been moved three times in each direction, though
given six movements).
The lever is provided with an arm f pivoted thereto by a screw fi and extend-
ing outward therefrom at an acute angle. The end of the arm fo is forked to
escape a pivot screw g¹ which fulcrums a segmental rack lever g upon the base a¹
and its forks are separated far enough apart to snugly receive a pin g³ project.
ing up from the said segmental rack lever g.
The arm fe is connected yieldingly to the arm f" by a spring f8 doubled, coiled
about a stud on the pivoted end of the lever f, and having its free ends bearing
with a spring pressure on two studs or pins f f10, one projecting upward from
the lever and the other from the arm f6. By connecting the arms f f of the
lever in this way, the arm fl may be reciprocated with a jerk, and the arm f6
will follow slowly after it.
The segmental rack meshes with a pinion h on an arbor h¹, there being on the
latter an escapement wheel 2 with which co-acts an escapement consisting of a
bar h³ weighted at both ends, and having pallets h h adapted to alternately
engage the teeth of the wheel. Now from the mechanism thus far described,
it will be seen that each time the lever f is moved in the direction of the arrow 2,
in Fig. 3, it will move the segment lever g in the opposite direction at a regular
or arbitrary rate of speed, this being accomplished by means of the spring con-
nection between the arms f" and fo and the escapement. If the star wheel be
moved step-by-step at a slow enough rate, the segment lever will travel through

page_text: a predetermined space, at an arbitrary or predetermined rate of speed, and will
be returned to its starting point each time before it is again actuated, but if the
star wheel be moved more quickly under the impulse of the clip on the bicycle
wheel, the lever will not have time to complete its travel forward before it is
returned to the starting point, the distance traveled being varied in accordance with
the intervals of time between the impulses given the star wheel by the clip. Hence
by indicating the variations in the movement or travel of the segment lever, or
indicating the point at which it is stopped before it reaches the end of its forward
throw, the speed at which the bicycle is traveling may be determined or indicated.
For instance, if it requires one second for the segment lever to complete its for-
ward movement, and the bicycle wheel revolves once a second, the movement of
the said lever will not be affected; but if the speed of rotation of the bicycle wheel
be increased to two revolutions per second, the segment lever will have completed
but one-half of its travel when the lever f has engaged it to return it to its starting
point, and hence by indicating the position of the lever when engaged, it will
be seen the bicycle is traveling at a speed twice as great as its initial speed.
The return movement of the lever is a little more rapid than the forward move-
ment thereof, so as to insure its being returned always to the same starting point,
this being accomplished by an additional spring g³, secured to a pin g on the
base a, coiled about the post and entering a notch g in the hub or enlarged
pivoted end of the segment lever g.
The pin g projects upwardly above the surface of the hub of the lever g, and
extends into a recess 26 in a lever i provided with a pivot stud projecting there-
through and extending into an aperture in the pivot screw g¹. The lever i is
formed with two arms 13 as shown in Fig. 8, and is also provided with a bent
lug against which bears a spring coiled around the stud 2 and having its
ends secured to the pin g before referred to. This spring operates to securely
hold the shoulder i* of the lever i against the pin g2 so that as the lever g swings
upon its pivot, the lever i swings with it.
The arm of the lever is bent downward to form a stop or shoulder against
which a lever j is forced by a spring secured to the post , as shown in Figs. 3
and 4.
The said lever j has a portion thereof curved in an arc about the centre of the
pivot of the stud and is pivoted at 2. Normally the spring j¹ holds the lever j
against the arm so as to prevent the lever i from swinging with the lever g,
and hence to permit the said lever i to move intermittently, the arm f" of the
lever is provided with a pin f1 extending into a V-shaped notch formed in
the lever j, as shown in Figs. 4 and 7, so that immediately upon the lever f being
moved in the direction of the arrow 2 in Fig. 3, the lever is thrust backwards
and allows the spring to throw the lever i against the pin 2 by which it is then
oscillated about its centre. The lever holds the lever i against movement during
the return movement of the segment lever, but as soon as the arm f¹¹ is moved
forward, the lever i is released and swings with, a quick movement backward to
meet the pin on the segment lever, and be moved forward with it to the end of
the movement of the segment lever g.
If the segment lever g is allowed to complete its travel in the forward direction,
the lever i will also move to the extent of its travel therewith, and as soon as the
said lever g begins its return movement under the impulse of the cam which in
turn is advanced step by step by the clip on the bicycle wheel, the lever is locked
against movement.
Pivoted upon the arm of the lever i is a setting device consisting of a lever k
pivoted in place by a screw . It has a notch to receive the stud by which its
inovement is limited in one direction, its movement in the other direction being
limited by a lug bent upward therefrom as shown in Fig. 8, to engage the side
of the arm 2 of the lever i.
The lever kis formed with a projecting arm
pivoted to the lever f may engage at intervals.
with which a spring held arm!
A rather strong spring secured

page_text: upon the arm f" of the lever f bears against the arm 7, the latter being provided
with a stop at which prevents the spring from moving it beyond a certain dis-
tance. Now, then, when the lever before described, engages the arm
lever and holds it against movement, the arm 7 engages the arm of the
lever and forces it towards the stud i¹.
of the
The lever is provided with a flat side k* which strikes against the straight
edge m on a lever m pivoted upon the said stud so that when the said lever k
is moved by the lever 1, it engages the lever m and moves it into parallelism there-
with, as will be readily understood.
On its end, the lever m is provided with an upwardly projecting pin m² work-
ing into a radial slot n' (Fig. 5) in a segment rack lever n, pivoted at 2 on the
under side of the plate d³.
The teeth on the segment lever n mesh with a pinion o on an arbor o¹ projecting
upwardly through the said plate 3 and through the dial plate a, and upon the
said arbor is placed the pointer 02.
Now, then, it will be seen that when the lever .moves the lever and it in turn
throws the said lever m into parallelism therewith, the pin m² on the latter travels
in the slot m¹, throwing the segment lever about its pivot, and thus moving
the pointer o accordingly.
In Fig. 10, I have illustrated the positions of the lever and the lever m before
and after it has been engaged by the lever 7.
It is now clear that if the bicycle wheel is traveling along the ground at the
rate of six miles per hour, the lever g is allowed to just complete its full forward
movement before its return, the pointer o³ will not be affected and will remain
therefore at 6, in Fig. 5.
Upon the speed of the bicycle being increased, so that a clip, engages the star
wheel twice every second, the segment is allowed to complete only one half of
its forward movement, before the arm fe of the lever f is moved in the opposite
direction and it is compelled to return before completing its forward movement.
Immediately thereupon, the lever 7 engages the arm of the lever k and throws
it towards the stud . The lever in turn throws the lever m into parallelism
therewith, and the pin m³ on the lever m travels along the slot n¹ of the segment
lever n and throws the latter about its pivot far enough to rotate the pinion and
cause the pointer of to point to the numeral 12, thus indicating that the bicycle
wheel is travelling along the ground at the rate of 12 miles per hour.
The clip engages a tooth of the star wheel c¹ and imparts one-sixth of
rotation thereto, whereby the three leafed came on the arbor c is likewise moved.
One of the leaves of the said cam engages the pin f3 and throws the lever f about
its pivot f, in the direction of the arrow 2 in Figure 3, so that the pin is operated
and throws the segment lever g to the left in the said last mentioned figure, its
movement being retarded and regulated by the escapement, and the escapement
wheel h² which is rigid with the pinion h. As soon as the lever f started to move,
the arm carried thereby released the arm + of the lever k, and the pin f¹ on the
said lever f engaged the lever j, and moved it out of engagement with the arm 23
of the lever i. As soon as the lever i was released, the spring turned the lever i
about its axis and caused the shoulder * thereof to engage the pin and follow
it in its movement.
Before the segment lever which is travelling slowly by reason of its engagement
with the escapement, can complete its stroke, the clip again engages a tooth
of the star wheel and imparts an impulse thereto. A leaf of the cam e engages
the pin f of the lever f and throws the latter in the direction opposite to which
it was previously moved. And it may be here stated that the star wheel is
rotated just far enough each time for one of the pins f f to remain on the top of
one of the leaves of the cam e. Immediately the pin f12 releases the lever jthe
spring causes the latter to engage the arm and hold it at the furthest point
it reached in its travel after the pin g² (with which it was engaged by the spring
as before stated). Immediately after this, the arm of the lever f engages the

page_text: arm of the lever k and throws the latter about the pivot k¹ until its flat edge k*
Fig. 10 engages the straight edge m² of the lever m and turns the said lever m
about its pivot. The stud m² of the lever m engages the segment lever n', and
throwing it about its pivot, causes it to partially rotate the pinion o' to move the
pointer o. Thus the positions of the segment lever g and the lever i when they
reach the farthest points of their travel is indicated by the pointer o³.
on the
This double operation is repeated for every two impulses imparted to the star
wheel, and when the latter is engaged six times, the toothed wheel
arbor c moves the pinion 2 one step, so that the distance travelled by the wheel
is registered.
It will be noted that the slot n¹ in the lever n is at substantially a right angle
to the lever m. This is a feature of some importance and its object is to compensate
for the loss of movement of the segment lever g as the rate of speed increases;
for instance, if the lever g makes a full forward stroke when the bicycle wheel is
traveling at the rate of 6 miles per hour, and makes only half a stroke when the
wheel is traveling at 12 miles per hour, and makes but one-fourth of a stroke when
it is travelling at 24 miles per hour, the graduations on the dial plate between 12
and 24 would be very fine, since the pointer o² would travel only half the distance
from 12 to 24 that it would from 6 to 12. .
Now by the pin and slot connection between the lever m and the segment lever n,
the greater the speed of the wheel, the nearer the pin m² gets to the pivot n², and
the greater is the movement of the lever n; that is to say, the same degree of
movement of the lever m causes a greater degree of movement of the lever n, the
nearer the pin m² approaches the pivot n². By this means, I am enabled to divide
the scale upon the dial into substantially equal divisions, as will be seen by
glancing at Fig. 5, since as the speed of the bicycle wheel is increased, the move-
ment of the pointer is practically increased in extent at the same ratio that the
movement of the lever m is decreased.
The arbor c which projects above the plate ³ is provided with a single toothed
wheel, which turns a pinion p', with a continuous step by step movement, the
pinion in turn intermeshing with a gear wheel 22 from which power is transmitted
to the train of numeral bearing disks q q¹ q² and q³.
Each time the star wheel is moved a step, the arbor c and the cyclometer
mechanism is actuated, while the toothed segment and the indicator mechanism
are actuated in the forward direction at every other impulse of the star wheel.
One impulse of the star wheel starts the segment lever g traveling forward at a pre-
determined rate of speed, and unlocks or releases the lever i, and the next impulse
returns the segmental lever to its starting point, locks the lever i against movement;
and actuates the setting mechanism to swing the pointer over the dial.
It will be observed that while the arm fl of the lever f is actuated positively
and practically instantaneously by the cam, (which cam is actuated by the star
wheel and the clip e, as has been fully described) yet the setting mechanism is
operated thereby through the medium of a spring and the segmental rack lever g
is advanced and returned also by a spring, so that there is no danger of any of
the parts of the mechanism being bent or broken.
Practically all of the operative parts of the mechanism herein before described may
be stamped out of sheet metal, and may be made in large quantities by machinery,
so that the cost of the device can be reduced.
It will be understood that I do not limit myself to the precise details which I
have described, as I may embody my invention in other forms of indicator, and
may vary the various parts thereof to suit my convenience. And when in the
following claims, I refer to the device being employed in connection with a bicycle
wheel, it will be remembered that it may be used with any other moving part,
such as a carriage wheel, a rotating shaft, or the like.
