I, CHARLES ABBOTT HANEY, residing at No. 473 Lafayette Avenue, Brooklyn,
in the State of New York, United States of America, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to such cyclometers as are employed upon bicycles, and'
to that particular class that is supported by a bracket arm secured in place upon
the end of the axle of the front wheel, and having a star wheel operated by a
roller secured by a clip upon the spokes of the front wheel; and the object of my
invention is to simplify the general' construction of this instrument by employing &
less number of parts, and parts that are not so delicately constructed as to easily
get out of order.
In carrying out my invention, I employ a case carrying a sight-glass which is
adapted to be connected to and supported from a bracket fastened at one end of the
axle of the front wheel by the usual clamping nut. This case is provided with an;
inner spring case and friction collar and an end cover with a hub for a central!
shaft upon which shaft is the star wheel for operating the cyclometer.
1 employ number wheels upon telescoping axles, the same surrounding the
central shaft, and the numbers on the number wheels being visible through
the sight glass as they progressively change position. The respective ends of the
number wheel axles are in the same plane, and their faces are each provided with
ten teeth with a notch at one tooth, in all except the innermost axle that surrounds.
the central.shaft.
A multiplying ratchet is. loose upon the central shaft, and alongside of said
ratchet, also loose upon the central shaft, is a pawl plate carrying a working pawl,.
and a cam plate is pivoted to the pawl plate and is slutted to receive, a crank, pin.
made in the central shaft, and is notched at the end opposite to its pivoted end to..
receive a, pin fixed in the end cover. A retaining pawl, connected to the case,.
bears upon the surface of the multiplying ratchet to hold the same frictionally in
position.
In the operation of the cyclometer, each revolution of the forward wheel of the
bicycle turns the star wheel one tooth, eight revolutions imparting to it one:
complete revolution. As the star wheel turns, the central shaft is rotated and, its
crank pin moves the cam plate, and the, pin, acting as a fulcrum, gradually swings
the cam plate back and forth. This movement swings the pawl plate and moves,
the working pawl, shifting the same progressively from engagement from one
tooth of the multiplying ratchet into engagement with the next tooth. This
operation is.accomplished with each revolution of the star wheel, in each of which
revolutions the working pawl engages one tooth of the multiplying ratchet, and as
there are nine teeth in the multiplying ratchet, and eight in the star wheel, it is
evident that 72 revolutions of the bicycle wheel will be required to impart one
revolution to the multiplying ratchet. With each complete revolution of the
multiplying ratchet, the working, pawl descends in a notch made in said ratchet
and engages with the toothed end of the axle of the first number wheel; that is,
with the one carrying the numbers representing fractional parts of a mile. With
each revolution of the multiplying ratchet, this number wheel is turned one tooth,

page_text: and with one complete revolution of the first number wheel the second number
wheel is similarly turned one tooth; the various operations of turning the number
wheels being progressive throughout, so as to count up the various miles covered,
and their fractions.
I, CHARLES ABBOTT HANEY, residing at No. 473 Lafayette Avenue, Brooklyn,
in the State of New York, United States of America, Manufacturer, 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:-
My invention relates to such cyclometers as are employed upon bicycles and to
that particular class that is supported by a bracket arm secured in place upon the
end of the axle of the front wheel and having a star wheel operated by a roller
secured by a clip upon the spokes of the front wheel, and the object of my invention
is to simplify the general construction of this instrument by employing a less
number of parts, and parts that are not so delicately constructed as to easily get
out of order.
In carrying out my invention I employ a case carrying a sight glass which is
adapted to be connected to and supported from a bracket fastened at one end of
the axle of the front wheel by the usual clamping nut. This case is provided with
an inner spring case and friction collar and an end cover with a hub for a central
shaft upon which shaft is the star wheel for operating the cyclometer.
I employ number wheels upon telescoping axles, the same surrounding the
central shaft and the numbers on the number wheels being visible through
the sight glass as they progressively change position. The respective ends of the
number wheel axles are in the same plane and their faces are each provided with
ten teeth with a notch at one tooth in all except the innermost axle, that surrounds
the central shaft.
A multiplying ratchet is loose upon the central shaft, and alongside of said
ratchet, also loose upon the central shaft, is a pawl platoicarrying a working pawl,
and a cam plate is pivoted to the pawl plate and is slotted to receive a crank pin
made in the central.shaft, and is notched at the end opposite to its pivoted end, to
receive a pin fixed in the end cover. A retaining pawl connected to the case bears
upon the surface of the multiplying ratchet to hold the same frictionally in
position. The details of the construction and the operation of the parts are
hereinafter more particularly described.
In the drawing,

improvement.
Fig. 2 is a view at the end of the case with the crank pin and pin of the cover in
section.
Fig. 3 is a plan of the cyclometer complete.

the case.

axle.
Fig. 7 is an elevation and Fig. 8 an end view of the third number' wheel and
its telescoping axle.
Fig. 9 is a plan of the inner spring case, and
Fig. 10 is an elevation of the central shaft.
The outer case is shown at a, the same comprising a tubular body open at one
end and having a back and an opening in the base at a to receive the bracket arm
shown by dotted lines and by which the cyclometer is supported as hereinbefore
stated. This case is provided with an opening and sight glass at 3, the sight glass
being secured thereto in the usual manner.
The inner spring case bis provided with a foot piece 6 entering a notch in the
outer case a, so as to prevent the inner case turning. This case is circular with the
ends of a distance apart to agree with the opening in the outer case a, and sight
glass, so that no obstruction is presented to the view of the number wheels. This
inner spring case carries the retaining pawl 5. c represents a friction collar
within the inner case and conforming thereto. The eud cover d fits within the
outer case and is provided with a hub di through which passes one end of the
central shaft l, and said central shaft is made with a crank pin l' and with a recess
in the opposite end to fit over a stud 2 formed with the outer case a, and the star
wheel m slips over the end of the shaft and is held in place by a clamping
Dut m¹.
The number wheels are represented at e, f, h, i, and k and these have telescoping
axles e, f,, and k', the axle el surrounding the central shaft and receiving
around it the axle 1, the various axles being superposed and having their ends
in the same plane and provided with surface teeth at 4 and all but the telescoping
axle e' with a notch in one tooth at 6. These number wheels beginning adjacent
in position to the star wheel represent fractional tenths, units, tenths, hundreds and
thousandths, the surface of the fractional tenths.wheel being numbered from one-
tenth up to ten-tenths, and each of the other number wheels numbered from 1 to 9
consecutively with a cipher.
The multiplying ratchet n surrounds the central shaft loosely, and the same is
made with nine edge teeth and a notch at ¹ coinciding with one tooth and the
retaining pawl 5 bears upon the surface of this ratchet to frictionally hold the
same in place. Alongside of this ratchet the pawl plate o, loosely surrounds
the central shaft and is in the form of a crank and carries the working pawl ol
pivoted thereto and provided with a spring o to keep the tooth of the pawl' pressed
against the surface of the multiplying ratchet.
A cam plate is pivoted at 8 to the pawl plate o and is provided with a notch to
receive the crank pin of the central shaft, and the opposite end of the cam plate
is notched' to receive the pin d' secured to the end cover d and which pin is a fixed
point or fulcrum.
It will be seen from Fig. 1 that the tooth of the working pawl o' is wider than
the multiplying ratchet, the same covering both the edge of the multiplying ratchet
and the exposed ends of the telescoping axles on which are the surface teeth at 4.
The friction collare within the inner case and almost surrounding the number
wheels retains the same in position except as positively moved by the mechanisın.
The operation of the cyclometer is as follows:
Each revolution of the forward wheel of the bicycle turns the star wheel mone
touth, eight revolutions imparting to it one complete revolution. As the star wheel
turns in this manner, the central shaft is rotated and its crank pin, operating
in the slot of the cam plato r with the pin d' acting as a fulcrum, gradually swings
the said cam plate from the position shown in Fig. 2 to a position with the crank
pin on the opposite side of the shaft. This movement swings the pawl plate o and
moves the working pawl o' from engagement with one tooth back into engagement
with the next tooth, and from this position, as the star wheel completes its movement
to the full revolution, the crank pin is brought back into the position shown in

page_text: Fig. 2, swinging the pawl plate o forward and imparting a partial rotation to the
multiplying ratchet, that is, a partial rotation to the extent of one tooth. As there
are eight teeth in the star wheel and nine in the multiplying ratchet, it is evident
that seventy-two revolutions of the bicycle wheel will be required to impart one
complete revolution to the multiplying ratchet. With each complete revolution of
the multiplying ratchet, the working pawl o descends in the notch at n' made in
said ratchet and engages with the axle k' of the number wheel k, this number wheel
being the one carrying the fractional tenths representing the tenths of a mile, so
that with each revolution of the multiplying ratchet the number wheel k and its
axle kare engaged at one of the teeth 4 and a tenth of a revolution is imparted
thereto.
The telescoping axle having a notch at one tooth will, when one complete
revolution is given to it, permit the point of the working pawl, as the same passes
into the notch of the multiplying ratchet, to also pass through its notch 6 to engage
one tooth of the telescoping axle it so as to turn the unit number wheel i from one
number to the next. The ends of the various telescoping axles, being each made
with teeth at 4 and all except the axle el with one notch 6 in one tooth, are, each
moved one-tenth in every progressive ten revolutions, so that, in other words, with
every complete revolution of the fractional tenths wheel the units wheel is moved
one figure, and with every ten movements of the units wheel and every
hundred movements of the fractional tenths, wheel, the hundredths wheel
is turned from one figure to the next, and with every ten movements of the
hundredths wheel and hundred movements of the units wheel and thousand
movements of the fractional tenths wheel, the hundredths wheel is inoved from one
figure to the next, and this ratio maintains through all the wheels and would
likewise maintain if the cyclometer registered' higher figures than those shown, the
movements being positive, regular and progressive, the number wheels being,
neanwhile, each held frictionally in place by the friction collar e within the inner
spring case.

The cam plate is provided with the open slot receiving the crank pin as the
same is a convenient form of construction and provided for readily placing the cam
plate and bringing the crank pin into the slot; and I prefer to employ a washer s
around the central shaft at the end of the hub against the star wheel to exclude
dust. The particular arrangement and construction of my improved cyclometer-
makes it possible to get the various parts necessary for the operation of the
instrument into small compass, of light weight, and at the same time of slight cost,
said parts being readily and quickly formed by machinery with comparatively
little hand labor in finishing.
