Improvements in Cyclometers.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings in the County of Middlesex, 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 primarily to a cyclometer adapted to be fastened to the
frame of a bicycle or tricycle, and preferably with its dial upward or in a position
to be read by the rider when in his saddle, and which is actuated by one of the
wheels of the machine or by some moving part thereof. It further consists in
various features of construction, organization and application, reference to which
will hereinafter be made.
In the accompanying drawings,
Figure 1 is a view in plan of the cyclometer attached to one fork of a bicycle.
Figure 2 is a detail view in elevation to represent the relation between the
cyclometer, fork and wheel.
Figure 3 is a plan view of the cyclometer, the dial being removed.
Figure 4 is a vertical section through the case, the works being removed.
The cyclometer is represented in the drawings as applied to a bicycle, and it is
shown as attached to the front fork of the machine. The cyclometer is represented
as consisting of a case A, preferably ornamental, and a train of gears contained in
the case, and actuated by a tappet or projection a, upon the spoke a¹ of the wheel a²
acting through the oscillating arm or lever b at the lower end of the shaft. The
case A has upon one side a clamp c of any desired form, by means of which it is
attached to the fork or other part of the bicycle. The clamp shown in the
drawings has two sections c¹ one or both of which may be yielding, and the ends of
which are adapted to be brought together and held by a screw passing through
holes in the outer ends of the sections, and the nut c³.
The oscillating arm or lever & communicates motion to the registering devices
through the shaft 6' by means of a spring pawl carried upon a plate in the
case A, and secured to the upper end of the said shaft. This pawl is pivoted to
the plate at 6. Its end engages when it is moved in one direction with the
ratchet wheel 6 mounted upon the stud 67. A spring 68 carried by the plate 6
bears against the end and holds the end 6 of the pawl in engagement with the
pin 61°. This pin is so placed that it maintains the forward end of the pawl in
contact with a tooth of the wheel when moving in one direction, and thereby
causes the wheel to be turned a portion of a revolution.
Upon the backward or reverse movement of the plate 6 and of the pawl, the
spring yields sufficiently to permit the pawl to clear the teeth of the wheel *.
The wheel has a pin projecting downward from its under surface which every
full revolution of the wheel comes into contact with a tooth of the wheel d¹.
This wheel is mounted upon a stud d, and has a long sleeve d' extending above the
dial D, and carrying the indicator hand d. This wheel communicates movement
to the wheel E upon the stud e by means of a pin e² projecting upward from the
wheel d¹. This wheel E has a sleeve e³ which projects upward above the dial and
carries the indicator e*.
The wheel E is in turn connected with the wheel F by means of the pin e,
the
said pin engaging a notch of the wheel F every rotation of the wheel E. The

page_text: wheel F is mounted upon the stud fand has a sleeve f¹ extending above the dial
and carrying the indicator f2. The wheel F is connected with the last wheel G of
the train by means of the pin which engages a tooth of the wheel + every
revolution of the wheel F. The wheel G is mounted upon the stud g and has a
sleeve g extending above the dial and carrying an indicator 2. There may be
detent pawls for various of the wheels, and I have represented the wheels 66 and E
as provided with the detent pawls and formed from or upon a single strip
thin metal held by the stud 3 at the centre of its length. The strip is represented
as bowed or curved upon each side of the pivot and as having its engaging ends
formed by bending the ends very nearly to a right angle. Similar detents andık
are provided for the wheels F and G by a similar bent strip of metal fastened.to
the case by the stud /³.
of
While I have referred to the studs as being carried by the case, I would say
that they may be mounted upon a separate plate adapted to be set in the case and
to be removable from it. With the organization shown in the drawings the
wheels E, F, G, are adapted to be turned as follows: The wheel d¹ and its
indicator to make one full revolution for every mile run; the wheel E and its
indicator, one full revolution for every ten miles run; the wheel F one full revolu-
tion for every hundred miles run; and the wheel G one full revolution for every
thousand miles run; and the dial D is correspondingly marked, that is, the indica-
tions for the indicator show quarters of miles, or any other subdivisions of a
mile desired; the indications for the other indicator hands represent in their
respective order mile divisions, ten mile divisions and one hundred mile divisions.
With the train connected as above described the indicator hands. of two wheels
will rotate in a direction opposite that of the indicator hands of the other two
wheels they may be made to turn in the same direction by interposing gears
between the various wheels. The tappet, or projection a is shown as comprising a
piece of metal, rubber, or other suitable material a³, removably secured to the
spoke a by a clamp a. This clamp has the opening as by which it is placed upon
a spoke, being of a width to receive a spoke, and the set-screw a which locks the
clamp and the tappet to the spoke, (see Figures 1 and 3). This also permits the
tappet to be adjustable upon the spoke longitudinally.
In operation the rotation of the wheel causes the tappet or projection a to strike
the arm and turn it sufficiently to move the pawl and actuate the registering
mechanism. After the tappet has cleared the arm bit is automatically returned to
its original position by means of a spring. This spring is represented as applied
to the form of construction above shown by means of a flat spring m, fastened at its
end m¹ and bearing against the straight edge' m² of the pawl wheel 3, (see Figure 3).
By attaching the cyclometer to the frame of the bicycle or tricycle and by causing
it to be actuated by a moving part of the machine, several important advantages
are obtained. First, it can be so located as to be easily read while the machine is
in motion; second, a much cheaper and simpler construction of cyclometer can be
used than where the cyclometer is attached to the wheel to rotate with it, as in the
ordinary construction.
Having now particularly, described and ascertained the nature of. this inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. The combination of a cyclometer attached to a fixed part of the frame of a
bicycle or tricycle, an operating arm or device carried thereby in a position
to be actuated by a moving part of the said bicycle or tricycle, and connected
with the registering mechanism of the cyclometer, substantially as described.
2., In combination with the fixed frame of a bicycle or tricycle, a cyclometer
attached to said frame with its reading face or dial uppermost, and having an
actuating device forming a connection between the registering mechanism of the
cyclometer and a moving part of the machine substantially as described.
3. In combination with the fixed frame of a bicycle or tricycle, a cyclometer

page_text: adapted to be operated by a moving part of the machine, and having a clamp by
which it is adjustably secured to the fixed frame, substantially as described.
4. In combination with the fixed frame of a bicycle or tricycle, a cyclometer
attached to the said frame, and having an actuating device comprising an oscil-
lating arm arranged to project into the path of a projection attached to one of the
wheels of the machine, and said operating projection procured to the wheel in a
position to come into contact with or strike the arm during the rotation of the
wheel, substantially as described.
5. The combination of a cyclometer attached to a fixed part of the frame of a
bicycle or tricycle, and having an actuating device extending into the path of
rotation of an operating projection, secured to one of the wheels of the machine,
and said operating projection detachably secured to the wheel, as and for the
purposes described.
6. The combination of a cyclometer attached to a fixed part of the frame of a
bicycle or tricycle, and operating devices carried thereby, adapted to be actuated
by a projection upon one of the wheels of the machine, said projection and means
for adjusting its position upon the wheel, as and for the purposes described.
7. The combination in a cyclometer for bicycles and so forth of the registering
train with the oscillating plate 3 carrying the spring pawl 62, arranged to engage
the wheel of the registering train, as specified, and the spring m, and the
actuating arm or lever e, as and for the purposes described.
