PROVISIONAL SPECIFICATION.
Automatically Indicating and Recording the Speed of Propelled.
T
Vehicles..
THOMAS PREECE, Electrical Engineer, 16, Thornhill Place, Thornbury, -Brad-
ford, Yorkshire, do hereby declare the nature of this invention to be as follows:-
For this purpose I conveniently attach a wheel to the vehicle arranged to
revolve freely when in contact with the road or track. In combination with the,
said wheel I provide a spindle or belt to transmitt the revolutions of the wheel
to a suitable spring or centrifugal govener. In combination with the said
govener I attach a pointer to indicate on a suitable scale or dial the speed of
the said vehicle. In combination with the said govener & pointer I place a
revolving cylinder or or disk driven by clockwork or its equivelant attached to the
cylinder or disk I place a piece of paper with the time and speed suitably scaled
off. In combination with the govener I attach a suitable inker so arranged to
record visably on the scaled paper the speed of vehicle.

Automatically Indicating and Recording the Speed of Propelled
Vehicles.
I, THOMAS PREECE, of 16, Thornhill Place, Thornbury, Bradford, in the County
of. York, England, Electrical and Mechanical Engineer, 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:-
-
For this purpose I conveniently attach a wheel to the vehicle to revolve freely
when in contact with the road or track. In combination with the said wheel I
provide a suitable spindle or belt to transmit the revolutions of the wheel to a
suitable spring or centrifugal governor. In combination with the said governor
I attach a pointer to indicate on a suitable scale or dial the speed of the said
vehicle. In combination with the said governor I place a revolving cylinder
or disc driven by clock work or its equivalent. Attached to the cylinder or disc
I place a piece of paper with the time and speed suitably scaled on.
In com-
bination with the governor I attach a suitable inker, and so arranged to record
on the scaled paper the speed of the vehicle. Any convenient method of
arranging the gearing to transmit the motion of the propelled vehicle to the
indicator and recorder may be adopted, for instance the shaft or spindle can
be geared on to the existing wheels of the vehicle, but for the purpose of this
invention I prefer the following method as shown attached to a tram-car' in the
accompanying drawings forming part of this specification in which similar
letters of reference indicate corresponding parts in each of the figures.
Fig. 1. Side elevation of car showing method of gearing.
Fig. 2. Half view indicator section showing governors.

page_text: Fig. 3. End elevation showing section indicator and recorder.
The wheel A I attach in a suitable manner to the frame of the vehicle. The
bevel wheel A' is attached to the wheel A, and geared into the bevel wheels B
and B which are attached to the shaft C. Care the bearings attached to the
frame of the car to support the shaft or spindle C. The bevel wheels 1 and D
are for the purpose of transmitting the motion to shaft or spindle E to the
indicator and recorder F, which is mounted on the vehicle F
G is the outer metal case of the indicator and recorder G2 metal case of
governor, H governor spindle, H² fixed collar on spindle, H³ collar seating and
spindle journal, H4 top end spindle journal, I governor spring, J, governor arms
with adjustable balance weights, J2, J³, arms connecting governor arms to sliding
collar, K, K³, sliding collars with rack gear attached, K³, K, arm attached to
collar K, to engage in rim of collar K², to draw the rack K³, down when the
governors are in motion. K³, is the spindle carrying wheel L, and wheel L2,
L³ and L are the supports where spindle K5 is pivoted. M, is the spindle
carrying the wheel M³, which is in gear with the wheel L². N, is the support
where the spindle is pivoted, and N2, is the support where the spindle M, passes
through the dial N³, to indicating needle N*.
O, protecting glass for dial and needle. F, base supporting pivot bearings, N,
N2, Land L, also forming the guide for the rack K, to prevent it from revolv-
ing with spindle H.
Q, box containing clockwork with revolving disc R, attached to clock spindle R³.
S, recorder inker needle attached to sliding collar K2, and the rack gear K³.
The disc R is for the purpose of attaching the scaled piece of paper; for the
inker needle to record thereon the general performance of the vehicle, for refer-
ence, and as a check on the driver or conductor.
It will be seen from the foregoing when the governor is not in motion, the
spring I closes the arms J, and thrusts the sliding collar K, and K², sliding
collars and rack gear K³ upwards.
The rack being geared to wheel L, the motion is transmitted, by the spindle K
to wheel L, and to wheel M³ by spindle M, and thus placing the indicator
needle to the zero position on the scaled dial, also the inker needle to the zero
line on the scaled paper.
It will also be seen, when the governors are in motion the spring I is pressed
downwards by the centrifugal force of the governor arms and balance weights,
the sliding collar K, and K³, sliding collars with rack gear K³, are pulled down-
wards by the arm K+, and thus imparting, through the wheels L and L2 attached
to spindle K³, and wheel M² attached to spindle M, the motion of the governors
to the indicator needle N, and recorder inker needle S.
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, I declare that what
my said
I claim is:-
1. The combination of the indicator and recorder, consisting of a needle indi-
cating on a scaled dial the speed of vehicle, and the inker needle recording upon
a scaled paper the speed and general performance of the vehicle, operated by
the governors substantially as herein shown and described.
2. The auxiliary wheel attached to the frame of the vehicle, for transmitting
the motion of the vehicle to the governor spindle of the indicator and recorder
substantially as herein shown and described.
3. The combination of the indicator and recorder described in the first claim,
and the auxiliary wheel A, described in the second claim, substantially as herein
shown and described, and for the purpose specified.
Dated this 20th day of July 1899.
