I do hereby declare the nature of this invention to be as follows:-
A simple and sure method of registering distance travelled by wheeled vehicles
and to indicate the same on a dial:
t
The mode of consruction is a follows-
A metal case, at the bottom of which I fix two pivots, one in centre of case,
the other a covenient distance off, upon each of these pivots toothed wheels revolve.
The first is a ratchet wheel worked by two springs alternately, to one is attached a
bolt passing through the case. Attached to the centre of ratchet wheel is a small.
cog wheel which imparts motion to a larger wheel placed on pivot N° 2, giving
to the second wheel a slower motion and so returned in like manner to a third
& fourth wheel. In the centre of last wheel directly over middle pivot a pin is
affixed passing throught the dial to which is attached a finger pointing to distance
travelled which is marked on the dial by an inner and outer circle, one recording
miles and the other parts of a mile. Attached to the hub of the wheel of the
vehicle, or any part that revolves with the wheel, a shaped piece of metal is
affixed, in such a manner that at every revolution of the wheel it catches a smaller
wheel, attached to a swivel, or by means of rods sliding within tubes or clips
(preferably tubes) communicating with a swivel, by which means it can be carried
to any required position, and at the same time giving the necessary action to the
spring or bolt passing through the case.

JOHN EDWIN HAYWARD, Post Box Manufacturer 6 Brougham St Birmingham
I do hereby declare the nature of my invention to be A SURE METHOD OF
REGISTERING DISTANCE TRAVELLED BY WHEELED VEHICLES and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The mode of construction is as follows:
A metal case at the bottom of which I fix two pivots one in the centre of case,
the other a convenient distance off, as shewn in drawing Fig. 1. Upon each of these
pivots toothed wheels revolve. The first is a ratchet wheel A, which is worked
by two springs B B alternately, one touching a bolt C passing through the case.
Attached to the centre of, ratchet wheel is a small cog wheel which imparts, motion
to a larger wheel placed on pivot N° 2, giving to the second wheel a slower motion
and so in like manner (on same, pivots) to a third and fourth wheel. In the centre
of last wheel directly over middle pivot a pin is affixed passing through the dial to:
which is attached a finger pointing to distanceitravelled which is marked on the
dial by an inner and outer circle, one, recording, miles and the other. parts of atmile
as shewn in drawing. Fig. 3. When a greater number of miles is travelled than is
marked on the dial it is recorded through a small aperture: F by means of a small
star shaped plate-which revolves on a pivot under, the dial as shewn by.dotted
lines in Fig. 3. In centre, of Fig. 3 underneath the dialais a small wheel with a
point attached, which moves at the same irate as the finger; when the finger has
travelled once round the dial the point on aforesaid wheel moves. the next point on
star shaped plate, each point recording the number of revolutions the finger has
made round tire dial

On upper part of plate D a spring is affixed part of which is fastened to the back
of case, to ease vibration produced by jolting of the vehicle: Attached to hub of
the wheel of the vehicle or any part that revolves with the wheelia shaped piece of
metal is affixed in such a manner that at every revolution of the wheel it catches
a smaller wheel attached to, the, lower end or arm of swivel. G, said swivel being
made to slide up or down within clips lettered H H H in drawing Fig. 1, to allow
for vibration of vehicle. On upper part of swiveliG.a projecting piece of metal I
is affixed placed against the outer end of bolt which bolt being forced out by
spring B, causes swivel G to turn or twist,.the same movement bringing forward
the wheel for farin at the opposite end of swivel which being caught and forced
back by the shaped piece of metal on the hub of the wheel as aforesaid, forces
bolt C against spring B which moves the ratchet wheel one tooth at every
revolution. Fig. 4 represents the bolt C worked by swivel G, to the lower end of
which is a rod sliding within a tube or clips, at the end of which is a small wheel
which is caught at every revolution by the piece of metal K on the hub or any
other part that revolves at the same rate. Fig. 2 is a piece of metal made to screw
to the spring of the vehicle with a movable plate which contains two slots-through

page_text: which screws pass one of which passes through slot E in Fig. 2 to screw hole E in
plate D Fig. 1, by which means the case can be adjusted to the best position for
the swivel to act against the hub of the wheel. (This method of fixing would not
be required for some wheeled vehicles.)
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 i
1. The combination of parts.
2. The method of working the toothed wheels from the two pivots as already
described.
3. The sliding bolt passing through the case to spring.
4. The method of working from the wheel to case by means of the swivel action.
