Velocipedes, Motor Cars, Tram Cars, Locomotives, and other
Vehicles.
I, HARRY COCKILL, of West Bank, 15, St. Paul's Street, Southport, in the
County of Lancaster, Leather Manufacturer, do hereby. declare the nature of
this invention to be as follows:-
My said invention relates primarily to improved apparatus designed to
indicate the speed or rate of travel of a velocipede or the like so that by
inspection of a dial or scale a rider can tell at a glance at what pace he is
progressing.
Under a suitable arrangement for this purpose I employ a spindle which is
caused to rotate by the revolution of the cycle wheel and to impart motion to
another spindle by means of bevel or other suitable gear. This second spindle
carries a ball governor or sliding load the rise or fall of the governor operating
a collar or nut working on a screwed spindle which carries a pointer or finger
moving against a suitably graduated scale or dial.
I do not confine myself to details so long as the movement of a sliding load
is caused to operate parts which actuate a finger or pointer working against a
scale or dial so as to indicate the speed of revolution of a cycle wheel or the
like.
By means of my invention a rider can tell by a glance at the dial at what
speed he is travelling at any particular time and may so maintain an even rate
of progress.
The apparatus would be particularly suitable for racing men and for training
purposes, its use dispensing to a certain extent with the need of pace makers.
A speed indicator such as I have indicated might also be employed in con-
nection with motor cars, tram cars or with locomotives. In the latter case by
an inspection of the dial a driver can tell at any moment at what speed his
engine is running.
When using the speed indicator for locomotives I may combine therewith a
suitable recording arrangement or apparatus which would preserve a record
of the speed from time to time throughout the length of a run so that a check is
kept upon the operations of the driver in running his engine. For instance if
an average speed is fixed, by an inspection of the recording sheet or strip the
periods when such speed was exceeded or not attained is readily ascertained.

page_text: lower links being pivotted to the upper links at g³ and to a sliding collar g
as clearly shown in Figs. 3 and 4. The sliding collar g bears against a spring 9
and is provided with two or more pins which pass through slots formed in the
sleeve or spindle c and engage an annular groove i¹ formed at the lower end of a
small sleeve i (see Figs. 6 and 8).
This sleeve is formed with a screw thread or spiral groove 22 and with a pin
or projection. The pin or projection bears in a vertical slot ¹ formed in
a sleeve which projects from the lower part of the cover b, whilst the screw
thread or spiral groove engages a projection formed on the lower end of
the spindle 7.
Thus if the sleeve be moved up or down revolution of the spindle 7 follows.
The sleeve i is raised or lowered by the governor G, as the spindle e revolves,
through the medium of the sliding collar g and pins h, as will be well understood
and imparts motion to the spindle 7. The spindle is formed with or carries a
pinion m which gears with a pinion n fixed on an arbor n¹ the pinion n being
compounded with a pinion 2. This pinion n² gears with a pinion o revolving on
an extension of the spindle 7.
The pinion o carries a pointer or indicator o¹ working against a marked dial
the pointer being operated from the sleeve i through the train of gearing.
Movement is thus transmitted from the governor G to the pointer p, so that
the speed of revolution of a wheel or part with which the runner d is in contact,
can be accurately indicated.
The dial is suitably graduated or marked so that the values of the move-
ments of the pointer o are given with great exactitude.
The sensitiveness of the governor or load G may be regulated by varying the
weight of the links or altering the tension of the spring g³.
In order to facilitate the attachment and adjustment of the apparatus to say
the front fork of a velocipede, I may employ a clip bracket such as is indicated
in Figs. 1 and 2. In this case the bracket e is formed with a clip c¹ which
embraces a limb of the front fork and is secured in position by means of a bolt e².
To this bracket e the projecting part a¹ of the casing a is connected by means of
a bolt passing through a slot e³ formed in the outer end of the bracket e.
By an arrangement of this kind, not only is the casing a free to swivel on the
connection f, but lateral adjustinent is provided for.
The shape of the clip bracket would vary to suit different designs of front
fork.
An indicator constructed in accordance with my invention will be found
particularly useful to cyclists as the apparatus gives an accurate indication of
the speed at which the rider is travelling so that he may maintain if desired an
even rate of progress throughout his journey.
The apparatus would also be useful to racing men and for training purposes,
its employment dispensing to a certain extent with the need of pace-makers.
In order to indicate the maximum pace attained during a ride I may utilise
double pointer arrangement such as is indicated in Figs. 11 and 12.
this case I employ a secondary and loosely mounted pointer q which is moved
In
ound by means of a finger or projection 2 carried by the pointer o¹. A forward
movement of the pointer o¹ carries round the secondary pointer 7 whilst on the
backward movement the pointer q is left behind indicating the maximum speed
ttained.
In Fig. 12, the pointer q is shown in dotted lines indicating the maximum
peed reached as 10 miles.
When required, the pointer q may be returned to zero by operating a milled
pindle or the like q
By the use of such a system of pointers trustworthy evidence of the highest
peed attained during a run can be recorded.
A speed indicator such as I have indicated might also be employed in con-
ection with motor cars, tram cars, locomotives and the like. In the latter

page_text: case by an inspection of the dial a driver can tell at any moment at what speed
his engine is running.
When using the speed indicator for motor cars and locomotives I may com-
bine therewith a suitable recording arrangement or apparatus which would
preserve a record of the speed from time to time throughout the length of a
run so that a check is kept upon the operations of the driver in running his
engine. For instance if an average speed is fixed, by an inspection of the
recording sheet or strip the periods when such speed was exceeded or not attained
is readily ascertained.
The sleeve or spindle & may be positively driven from a moving shaft or part
by means of bevel gear or the like, or the end of the sleeve or spindle may be
suitably coned or formed to engage the turning centre of a shaft or axle.
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 what
I claim is
1) The general arrangement, construction and combination of parts com-
prising the improved speed indicator, substantially as herein described and
shown.
2) A speed indicator, having a governor or load G worked from the moving
part so as to impart motion to a sleeve such as which in turn operates a
spindle, the movement of such spindle being transmitted through gearing to
a finger or pointer o¹ moving against a marked dial or scale, substantially as
herein set forth.
