IMPROVED MEANS OF, AND APPARATUS TO BE EMPLOYED IN CONJUNCTION WITH MECHANISM FOR REGISTERING THE DISTANCE TRAVELLED BY BICYCLES TRICYCLES, OR OTHER VEHICLES
Year: 1884

page_text: I, ARTHUR HENRY HERNU, of Hornton Street, Kensington, in the County of
Middlesex, Mechanical Engineer do hereby declare the nature of said Invention
for IMPROVED MEANS OF, AND APPARATUS TO BE EMPLOYED IN CONJUNCTION
WITH MECHANISM FOR REGISTERING THE DISTANCE TRAVELLED BY BICYCLES
TRICYCLES, OR OTHER VEHICLES, to be as follows:-
'This Invention has for its object improved means of, and apparatus for registering
the distance travelled by bicycles, tricycles, or other vehicles, and consists in the
mounting of an ordinary cyclometer to the upper part of a hub lamp of any
convenient type. This cyclometer is provided with a primary worm-wheel into
which engages a worm on the axis, or neck of the hub, of the road wheel.
This worm is advantageously in two parts, and connected to the neck of the
hub, or the axis, in any convenient manner such as by clamps, screws, hinges or
couplings. It will thus be seen that the cyclometer is fixed, and that, by the
rotation of the wheel, the worm connected therewith will actuate the well-known
mechanism of the cyclometer.
Instead of a worm and worm-wheel, it may be a spur, or friction wheel, on the
neck of the hub, gearing with the mechanism of the cyclometer, which latter, I
propose, in all cases should be employed on the hub lamp, and not to be connected
and revolve with the wheel as heretofore.
By the aforesaid means, the distance travelled can be seen at a glance whilst the
machine is in motion.

page_text: I, ARTHUR HENRY HERNU, of 18, Hornton Street, Kensington, in the County of
Middlesex, Mechanical Engineer, do hereby declare the nature of my Invention for
"IMPROVED MEANS OF, AND APPARATUS TO BE EMPLOYED IN CONJUNCTION
WITH MECHANISM FOR, REGISTERING THE DISTANCE TRAVELLED BY BICYCLES,
TRICYCLES, OR OTHER VEHICLES,' and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The object of my Invention is an improved means of, and apparatus for,
registering the distance travelled by bicycles, tricycles, or other vehicles.
To carry out my Invention, I mount an ordinary cyclometer on the top of a hub
lamp of any convenient type, or in any other correspondingly suitable position
according to the nature of the vehicle to which it is desired to apply the Invention.
The actual position of the cyclometer is of secondary importance, provided that it
can be accurately geared to the road wheel, its face being, at the same time,
conveniently visible to the rider or driver, although I propose to always mount it
upon the hub lamp where such a position is practicable, instead of fixing it so as
to revolve with the wheel as heretofore, the weight of the lamp serving to keep
the cyclometer in a horizontal position.
The cyclometer is provided with a primary worm wheel, into which engages a
worm on the axis or hub of the road wheel. The worm is advantageously made
in two parts, so that it can be fixed on the axis or hub of the wheel in any
convenient way, e.g. by clamps or screws or their equivalent, and hinges.
It will thus be seen that the cyclometer is maintained in a horizontal position,
and that the rotation of the wheel registers itself thereon by means of the worm
gearing above described. I do not confine myself to worm gearing for communi-
cating the motion of the road wheel to the cyclometer. Any other type of
gearing, such as a spur, or friction wheel, or cam, on the hub or axis of the road
wheel, and gearing with the inechanism of the cyclometer, may be used.
In order that my Invention, and the method of advantageously carrying the
same into effect, may be thoroughly understood, I refer to the accompanying
Drawings, which are to be read with this Specification as a part thereof.
parts are marked throughout by the same reference letter.

modification of parts, necessary to adapt it to any other vehicle, are too trivial to
need illustration, as they do not go to the essence of my Invention.
Figure 2 is a plan of the cyclometer, worm wheel, and worm, the latter in
section,
Figure 3 is a sectional elevation of the cyclometer with its connecting screw,
the worm wheel and box, and worm.
Figure 4 is a plan of the worm wheel, first motion wheel of the cyclometer, and
the wheel box.
Figure 5 is a plan corresponding with Figure 3.
Figure 6 is an end elevation of the cyclometer as drawn in Figure 1, shewing
the means of connecting the cyclometer upon the top of the hub lamp.
Figure 7 a plan of the cyclometer bracket.
Figure 8 is the cover of the wheel box shewn in plan in Figure 4.
A is the hub lamp suspended from the worm socket B, by the ordinary double
loop C controlled by a tightening screw D. A bracket E is rivetted to the loop,
and carries the cyclometer F.

page_text: The worm socket B is split and hinged as shewn, and is caused to grip the
axle G tightly by set screws b, b. The worm, B¹, thus revolves pari passu with
the road wheel, transmitting its rate of motion to the cyclometer F, by means of
the worm wheel F¹.
F' is the worm wheel box, F³ the first motion wheel of the cyclometer, and F*, F",
the nuts and screws entering the grooves E¹, E', by which the cyclometer is
attached to the bracket E. By loosening these screws and drawing the cyclometer
backwards, it is put out of gear, and ceases to register.
The lamp can be replaced when desired by any suitable weight sufficient to keep
the cyclometer in the horizontal position, so as to be clearly visible to the rider or
driver.
And now having particularly described and ascertained the nature of my said
Invention, and in what manner the same is advantageously carried into effect,
I declare that what I claim is
First The hereinbefore described combination of hub lamp and cyclometer
with worm wheel or equivalent gearing for transmitting the rotation of the road
wheel to the first motion wheel of the cyclometer.
Second-The use with a bicycle or tricycle, of a cyclometer to register the
distance travelled, the same being geared to the axis or hub of the machine and
maintained by the weight of the lamp (or its substitute) in a horizontal position
so as to be at all times conveniently visible to the rider, substantially as herein-
before described with reference to the accompanying Drawings.
Third The use of a cyclometer maintained in a horizontal position by a
pendant lamp or suitable substitute, in combination with suitable gearing to
transmit the motion of the road wheel to the cyclometer for the purpose of
registering the distance travelled, substantially as hereinbefore described with
reference to the accompanying Drawings.
