An Improved Speed Indicating and Recording Apparatus.
FRANCIS MALGER STAUNTON, 2, Hainault Villas, Harold Wood, Romford,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows.-
My invention relates to improvements in mechanism for recording the speed
of motors or other moving machinery, which mechanism is controlled by means
of centrifugal force In adapting my invention to recording or indicating the
speed of motor cars I proceed as follows:-
"
On any convenient moving portion of the driving mechanism of the motor
car I anange one or more governor balls" adapted to move a distance away
from a given point, according as the speed of the motor varies. A pointer 18
suitably connected to the governor ball or balls, so that any variation in the
position of the latter (caused by variation in the speed of the motor) will be at
once indicated by the said pointer, on a dial or scale placed near it This dial,
or scale can be marked off so that the position of the pointer on it will indicate
say the number of miles per hour, at which the motor is travelling In order
to record the maximum speed which the motor has attained, I may provide
a second pointer, or indicator, adapted to be pushed along the scale, or dial, by
the speed actuated pointer, to the highest position reached by the latter, where
it will be left until set back to zelo by hand
There are many other ways of recording the various positions occupied on
the scale, or dial, by the speed actuated pointer, for instance: I may fix on it a
pencil, o style, which when arranged to mark on a regularly revolving roll
of paper, would provide a perfectly accurate record of the variations in speed of
the motor, as well as the maximum speed attained
I
may
also use any known means of damping down the action of the apparatus,
and rendering the movement sluggish

I, FRANCIS MALGER STAUNTON, of 2, Hainault Villas, Harold Wood, Romford,
n the County of Essex, Engineer, do hereby declare the nature of this invention
[Price 8d.]

page_text: 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 apparatus for recording the speed of motors or other
moving machinery-said apparatus being especially adapted for recording the
maximum speed attained by motor cars
In adapting my present invention for showing and recording the maximum
speed of motor cars I proceed as follows.-
From any convenient moving portion of the driving mechanism of the motor
car o from the road wheels thereof 1 operate suitable" governo balls" adapted
to move a distance away from a given point according as the speed of the motor,
or speed of travel of the car, varies
An index finger or pointer is suitably connected to the "governor balls" or
arranged to be operated thereby in suchwise that any variation in the position
of the latter (caused by variation in the speed of the motor or car) will be at once
indicated by the said pointer on a dial or scale placed near it
This dial or
scale can be marked off (calibrated) so that the position of the pointer on it
will indicate say, the number of miles per hour at which the motor car is
tiavelling.
In order to record the maximum speed which the motor or motor vehicle has
attained, I provide a second and independent pointer or indicator adapted to be
moved along the scale or dial by the speed actuated pointer to the highest
position reached by the latter where it (the said second pointer) will be left
(until set back to zero by hand) and thus form a record of the maximum speed
attained.
Any other suitable way may be employed for recording the various positions
on the scale or dial of the speed actuated pointer, for instance I may fix on
said pointer a pencil or style which when arranged to mark on a regularly
revolving 1oll of paper would provide a perfectly accurate record of the variations
in speed of the motor or motor vehicle as well as the maximum speed
attained
I may also use any known means of damping or gearing down the action of
the apparatus and rendering the movement sluggish
And in order that my invention may be easily understood and readily carried
anto practice I will proceed to describe same with reference to the accompanying
sheet of diawings which illustrates my speed recording apparatus adapted for
use on a motor car.
Fig 1 is a front view of the exterior of the apparatus
Fig 218 side view thereof.
Fig 3 18 plan or top view of Fig. 2
a is front, of the apparatus, mounted on the main fiame b.
16 pulley adapted to be driven by a band from any desired moving part of
the motor or motor vehicle.
This pulley through the medium of the bevel gears c d revolves the shaft d
Journalled in the frame b, on this shaft d 18 mounted a pair of "
"
governoi
balls e the latter being connected by the links el to the sleeve f which is there-
by moved along the shaft d by the action of the governor balls in the well-
known manner. Between the flanges f¹ fl on said sleeve f 18 held the colla q
which latter by means of the short link q operates the lever h pivoted at h' to
the main fiame b At the end of said lever his attached one end of a cord
or flexible connection the other end of which latter 18 attached to the drum x
and has several turns wound round same; a second cord or flexible connection
18 attached to said drum 2 and has several turns wound round same while the
other end of said flexible connection j 18 attached to the spring arm k fixed at k¹
to the frame b, these flexible connections and are wound on the dium r in
opposite directions so that when one cord is unwound off said drum it will wind
up the other cord thereon.

page_text: The drum through the bevel gear ¹y revolves the index finger or pointer y
around the axis
*
18 a second and independent (.e idle") index finger or pointer adapted
to be moved around the axis y³.
This pointer z lies in the path of travel of the point y³ (Fig. 2) of said pointer y
so that as the latter is revolved it will push the pointer z before it (when both
pointers y and z have first been placed back at zero as shown in Fig. 1) to the
furthermost point to which the arin y is moved through the action of the governor
balls and connecting mechanism as aforesaid and then on any reduction of
the speed or stoppage of the motor or motor vehicle the pointer y will recede or
return to zero and leave the arm z in the furthest position to which same has
been removed, and said arm z, which is made to move rather stiffly, will remain
in such furthermost position to which it has been moved by the pointer y, and
thus indicate the highest speed at which the motor or motor vehicle has been
running.
The aim z can be re-set back to zero direct by hand or by any suitable hand-
operated mechanism (not shown) if desired
On the shaft d I may if desired also provide a pinion d* and train of wheels m m
(geared down) to operate a meter index arm o and shaft n by which means the
total distance travelled can also be indicated in the same apparatus, or any
other suitable distance-recorder may be employed in place of the one illustrated
such meter or distance recording instrument per se being well-known and in
common use and forming no part of my present invention
The operation of the speed recording apparatus is as follows:-
As the speed imparted to the pulley increases thereby the governor balls e
will move the sleeve f along the shaft d towards the pinion thereon-as
indicated in dotted lines in Fig. 2-and thereby the lever h will be moved
to the position shown in dotted lines in said Fig 2 and consequently the end h³
of said lever h will be moved (as indicated in dotted lines) and by means of the
flexible connection will revolve the drum a and the latter in turn through the
bevel gearry will move the arm y through part of a circle over the dial w
according to the speed attained, that is according to the "lift" of the governor
balls e, and thereby the recording pointer z is moved from zero through a cone-
sponding part of a circle around the dial w and is left behind on the return of
the pointer y when any reduction of speed occurs and thus records the maximum
speed attained
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that I make
no claim whatever in respect of the aforesaid parts marked & m n and o either
