PROVISIONAL SPECIFICATION.
An Improved Turning Plate for Electrically or Mechanically
Propelled Vehicles.
I, WALTER CHARLES BERSEY, of 39, Victoria Street, in the City of West-
minster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a ball bearing turning plate for electrically or
mechanically propelled vehicles and it consists of a Hanged annular plate or ring
of shaped section which is fixed to the body of the vehicle the vertical flange or
annulus acting as the king-bolt, in combination with a similar ring fixed to the under
carriage the vertical member of the last mentioned ring fitting about the corre-
sponding member of the upper plate but being rounded on the inner surface in the
vertical direction, or in other words flared upwards and downwards to permit of the
necessary play. Between the horizontal members of the two rings balls are applied
to run in circular grooves in the two members in order to support the weight of the
carriage body and lessen the friction in turning which is effected by a hand wheel
shaft extending up to the driver's seat or platform and geared by a pinion on its
lower end with teeth on the edge of the lower ring.

An Improved Turning Plate for Electrically or Mechanically
Propelled Vehicles.
I, WALTER CHARLES BERSEY of 39, Victoria Street, in the City of West-
minster, 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 :-
This invention relates to a ball bearing turning plate for electrically or
mechanically propelled vehicles and is illustrated in the accompanying drawings
forming part of this Specification wherein Figure 1 is a central vertical section and
Figure 2 a plan partly broken away of the improved turning plate.
Referring to these drawings A is an annular plate or ring which is bolted to the
main frame or body B of the vehicle, the plate having a downwardly projecting
tubular trunnion a which acts as the king-bolt, and C is a similar plate or ring fixed
to the under carriage D and having a downwardly projecting annular flange or
member e which fits about the corresponding member a of the upper plate A. The
inner surface of the member c is rounded in the vertical direction or in other words
flared upwards and downwards to permit of the necessary play between the parts.
An outwardly projecting flange al is preferably provided upon the lower end of the
trunnion a to prevent the latter accidentally rising out of its bearing. Between

page_text: the horizontal portions of the two plates A and C a set of balls E are applied to
run in circular grooves e e¹ formed in the two plates in order to support the weight
of the carriage body and lessen the friction in steering or turning the vehicle. The
steering is effected by a hand wheel shaft F extending up to the driver's seat or
platform, the shaft being mounted in bearings supported by the main frame or body
of the vehicle and geared by a pinion f fast on its lower end with teeth on the edge
of the lower plate C as shewn.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what
I claim is
The herein described improved ball bearing turning plate constructed and applied
to operate substantially as and for the purpose specified.
