PROVISIONAL SPECIFICATION.
Apparatus for Actuating by Pneumatic Pressure Cyclometers and
other Distance-measuring Instruments.
I GASTON HERVIEU of 47 Mall Road Hammersmith in the County of Middlesex
Engineer, do hereby declare the nature of this invention to be as follows:-
My apparatus consists of a bellows formed by an india-rubber ball placed
between two hinged plates secured to the frame of the cycle or carriage and against
which a rolling stud secured to one of the wheels of the cycle or carriage, rubs on
the rotation of the wheel compressing the ball and causing on each occasion of its
passing a jet of air to be projected through a metal or other tube to a second and
smaller india rubber ball or bellows attached to the cyclometer or measuring instru-
ment and which on being thus expanded by this air jets presses on each pulsation
against a lever or other mechanical means of action of the cyclometer or measuring
machine and registers the number of revolutions performed by the wheel. By
this means the bellows being attached to the most stable wheel of the cycle or
carriage and the rolling stud being attached to the spokes of the same wheel
the pneumatic power is transmitted by the tube to the most convenient position
for the cyclometer or measuring instrument. Say in a cycle on the centre of
the handle bar under the eye of the rider or in the interior of a carriage or on
the splash board in front of the driver.
:
A cylinder and piston or other convenient means may be substituted for the
ball or bellows and the cyclometer or measuring instrument actuating lever
worked by a small air-pump or other suitable means-the chief feature of my
apparatus being that the distance measuring action is performed by the wheel
which travels most steadily and most uniformly on the road and that the
record thus made is transferred by uniform simple and reliable means to the
particular part or portion of the cycle or carriage most convenient to rider
observer. Further that the cyclometer or measuring instrument is not subjected
to any disturbing influences such as the jumping of the front wheels off the
road and the variations of distances and speeds caused by the turning from
side to side of the front wheels in steering a cycle or directing the course of a
carriage the hind wheels of all cycles and of all carriages being the most
uniform and least subject to disturbances.

Apparatus for Actuating by Pneumatic Pressure Cyclometers and
other Distance-measuring Instruments.
I GASTON HERVIEU 47 Mall Road Hammersmith, London, W. Watch Manu-
facturer 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 apparatus consists of a bellows formed by an india rubber ball placed in
between two hinged plates secured to the frame of the cycle or carriage and against
one of which a rolling stud secured to one of the wheels of the cycle or carriage
rubs on rotation of the wheels compressing the ball and causing on each occasion of
its passing thus a jet of air to be projected through a metal or other tube to a

measuring instrument which on being expanded by the air jets presses on each
pulsation against a lever or other mechanical cause of action of the cyclometer
which registers the number of revolution performed by the wheel.
By this means the bellows being attached to the most stable wheel of the cycle
or carriage and the rolling stud being attached to the spokes of the same wheel the
pneumatic power is transmitted by the tube to the most convenient position for the
cyclometer or measuring instrument say in a cycle on the centre of the handle bar
under the eye of the rider or to the interior of a carriage, or on the splash board in
front of the driver. A cylinder and piston or other convenient means may be
substituted for the ball or bellows; and the cyclometer or measuring instruments
actuating lever worked by a small air pump or other suitable means, the chief
feature of my apparatus being that the distance measuring action is performed by
the wheel which travels most steadily and most uniformly over the road and that
the record thus made is transferred by uniform simple and reliable means to the
particular part or portion of the cycle or carriage most convenient to the rider or
observer. Further that the cyclometer is not subjected to any disturbing influences,
such as the jumping of the front wheels off the road and the variations of distance
and speed caused by the turning from side to side of the front wheels in steering a
cycle or directing the course of the carriage. The hind wheels of all cycles and of
all carriages being the most uniform and least subject to disturbances.
It is understood that I do not claim any particular form or design of cyclometers
nor any special system of measuring instrument but my attachment may be employed
in any existing form of cyclometers by a slight variation in its details. In general
principle my invention may be described as consisting essentially of a box or con-
taining box or case (B) containing bellows or any india rubber ball (A) the box (B)
is attached to the fork of the cycle (F) by a clamp (C) tightened by nut (N) or
some other means of attachment. The bellows or ball (B) has a tube of rubber or
metal (T) communicating with the cyclometer or indicator (H).
There is an arm or hinged plate (D) attached to the box (B) which compresses
the ball or bellows (A).
Fixed on a convenient position on the spokes or the hub of the cycle or vehicle
is a revolving stud (E) so that each revolution of the wheel the stud presses on the
arm or hinged plate (D) and compresses the bellows expelling the air contained
therein and forces a jet along the aforesaid tube. Fixed to the handle bar (Q) or
in any convenient position on a cycle or on the splash board or inside a vehicle is a
cyclometer or distance measuring indicator of any existing form.
Inside the cyclometer is another bellows or pump (J) in communication with the
air tube connected with the bellows on the hub or axle (A) and actuating the
cyclometer by means of a current from the bellows (A) raising bellows (J) forcing
the flap up, which flap by means of a spring or pawl engages in the cogs of a ratchet
and drives the mechanism thus indicating the distances by discs or hands. The
advantages of this system may be briefly stated to be as follows, that the source of
movement may
be quite near or at a great distance from the spot where such
movement is indicated or recorded. The cyclometer may be placed immediately
under the eye of the rider or driver and thus the distance travelled may be
ascertained without dismounting. The cyclometer being placed on the handle bar
it is not subject to the violent vibrations and friction that takes place on the hub
and what is of considerable more importance it is in a position that prevents the
mud or dirt accumulating on it or in its bearings.

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:
Claim 1. Attached to any existing form or type of cyclometer-bellows or
similar contrivance by which a jet of air is propelled through a tube or tubes in
such manner that it actuates the mechanism of such cyclometers, substantially as
herein described and set forth.
Claim 2. In a cyclometer means by which a lever or arm may replace the
existing cam or work, such lever to have the necessary spring or pawl to actuate a
ratchet and be worked raised or lowered by means of a pump or bellows etc. as set
forth in the designs herewith.
Claim 3. In connection with a cyclometer of any known type or form an air
tube of metal or rubber which is fixed to a pump or bellows which pump or bellows,
is actuated by means of a pressure from a revolving wheel or stud attached to the
spokes or hub of a cycle wheel, or wheels of any other vehicle the rotation of which
wheels are recorded substantially as herein set forth and described.
Claim 4.-The mechanism with any modification necessitated by the peculiarities
of the particular case substantially as the design appended hereto.
