Improvements in and relating to Cyclometers.
I, WILLIAM WALLACE DUDLEY, Inventor, a citizen of the United States
of America, of Monmouth Street in the City of Trenton, County of Mercer
and State of New Jersey, one of the United States of America, 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 relates to improvements in cyclometers, as will be hereinafter
fully described, reference being had to the accompanying drawings, in which-
Figure 1 is a perspective view of the cyclometer;
Figure 2 a plan view thereof, with the bezel, hands and dial removed;
Figure 3 a like view with the disc form indexes removed, in addition to the
other parts;
Figure 4 a section on the line e-x of Figure 2 ;
Figure 5, a section on line y-y of Figure 2.
Letters of like name and kind refer to like parts in each of the figures.
The object of this invention is to provide, in a very compact form, and of
simple construction, a cyclometer for bicycles, more especially, of the kind known
as the "ten thousand mile" cyclometer; that is, a cyclometer capable of
registering miles up to said number, and to this end, said invention-
Consists in the cyclometer having the construction and combination of parts,
substantially as and for the purpose hereinafter specified.
In the carrying of the invention into practice, I employ a, preferably, circular
base or supporting plate A, at the center of which is fixed a pin or post B.
Upon said post is journalled an arbor C, that carries a worm wheel D meshing
with a worm E at the inner end of a shaft F, upon whose outer end is placed
the customary star wheel G, by which motion is imparted to the registering
mechanism of the cyclometer from the bicycle wheel in a well-known way.
Said shaft F is journalled in a tube H, being confined from longitudinal move-
ment by means of a screw I passing through the tube and entering a circumferential
slot fin the shaft.
Secured to the upper end of the arbor C, is a hand or pointer K, that travels
over a dial l, marked on the face of a disc or plate L, which serves to indicate
fractions of a mile, one revolution of the pointer around the dial taking place
for each mile.
Also fixed to said arbor C, so as to rotate therewith, is a disc M, having a
single tooth m that, at each revolution of the disc, is adapted to engage a
peripheral notch n in a wheel N having a series of such notches, and fastened
to an arbor O, that is mounted to revolve upon a pin or post P fastened to
the base plate A. Carried by said arbor at its upper end, is a disc Q, having
marked on its face, in a circular series, numerals from 0 to 9, which, in turn, are
displayed through an opening in the dial plate L, and denote units.
Fastened upon, and rotating with the arbor O, is a disc R, similar to the disc M,
having a single tooth r that, at each revolution, is adapted to engage and partially
turn a peripherally notched wheel S, similar to the wheel N, upon an arbor T,
that at its upper end, carries a disc U marked, like the disc Q, with a series
of numerals from 0 to 9 which, successively, are displayed through an opening
in the plate L and denote tens. The arbor T revolves around a second arbor T
which revolves around a pin or post V, fastened to the base plate.

page_text: For denoting hundreds, a third disc W is employed, precisely like the others,
bearing the numerals 0 to 9, for which is provided the display opening in the
plate L, which disc is mounted upon the upper end of an arbor X journalled on
a pin or post Y attached to the base plate A, and receives a periodic motion
from the arbor T by means of a single toothed disc Z and a peripherally
notched wheel A¹.
To employ similar indicating means to the numerals discs Q, U, and W, for
indicating thousands, would require enlargement of the size of the cyclometer,
and be otherwise objectionable, and I have, accordingly, provided a different means
which will enable the size of the instrument to remain the same as it is, if no
higher indication than hundreds is provided for, and without disturbing the
symmetrical appearance of the instrument.
Said thousands indicating means consists of a small dial having a circular series
of numerals from 0 to 9 marked on the dial plate L, concentric with the tens
disc U, and a hand or pointer B', to co-operate therewith carried by an arbor T¹
journalled within the arbor T, and upon the post V, and having attached to its
lower 'end a peripherally notched wheel D' that is adapted to be engaged and
moved by a one-toothed disc E', carried by the hundreds disc arbor X.
The dial plate L is conveniently fastened in place to the two posts P and Y,
by means of screws, as shown, and the entire mechanism is enclosed in a suitable
casing F, having a glass top or cover G', and provided with means for attachment
to the frame of a bicycle.
It is thought the operation of the mechanism has been made clear in the
description hereinbefore given, and hence, a special description of the operation is
not deemed necessary.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is :-
1. In a cyclometer, the combination of a series of indicators comprising numerals
bearing discs, means for actuating them, an indicating mechanism concentric with
one of said discs, and means for actuating the same, substantially as and for the
purpose specified.
2. In a cyclometer, the combination of a series of indicators comprising numerals
bearing discs, means for actuating the same, a dial concentric with one of said
discs, a pointer for said dial, and means for actuating said pointer geared to one
of the disc mechanisms, substantially as and for the purpose shown.
3. In a cyclometer, the combination of a series of indicators comprising numerals
bearing discs, an arbor for each of said discs, gearing between the arbors, a dial
concentric with one of said discs, a hand for said dial, an arbor carrying said
hand, and gearing between said arbor and one of the disc arbors, substantially as
and for the purpose set forth.
4. In a cyclometer, the combination of a driving shaft having a worm, a worm
wheel, an arbor on which the latter is mounted carrying a hand, a plate having a
dial for said band, a series of disc indicators having each an arbor, said plate
having a display opening for each indicator, gearing between each of said arbors
and the worm wheel arber, a dial on said plate concentric with an intermediate
one of the discs, a hand for said dial, an arbor passing through the disc arbor
carrying said hand, and gearing between said hand carrying arbor and the arbor
of the highest indication disc of the series, substantially as and for the purpose
described.
