I, WILLIAM SCHEU, of 63, Wortley Lane, Leeds, in the County of York Butcher,
do hereby declare the nature of this invention to be as follows;-
;--
The object of my invention is to construct motor cars so that they are easily
turned upon their own centres, and so that there is more control in steering the
same than in the present construction.
I construct the body of the motor car with wheels at each side in centre and a
wheel at both the back and front, the back and front wheels being the driving
and steering wheels, and are mounted on turntables or pivots upon suitable frames
with antifriction rollers thereon. The chain and chain wheels are upon the rim
or felloe of the wheels, or pin wheels and pinions may be employed. The shaft
bearings of the wheels are provided with spiral springs.
The whole of the wheels and their brackets or turn-tables are carried upon a
suitable steel frame. The back and front wheels are connected by two shafts and
differential gearing in the centre. Upon one half of each plate or turntable are
teeth, each being connected by worms and a diagonal shaft, which in turn is
connected to the steering handle by two bevel wheels, one of larger diameter
than the other.

Improvements in or relating to Motor Cars.
I, WILLIAM SCHEU, of 63, Wortley Lane, Leeds, in the County of York Butcher,
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:―
The object of my invention is to construct motor cars so that they may be easily
turned about their own centres, and so that there is more control in steering than
in the present construction.

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of my improved driving and steering gear for motor
cars.
Fig. 2 is a plan of same.
Fig. 3 is an enlarged elevation (half in section) of pivotting mechanism for front
and back wheels.
Fig. 4 is a plan of Fig. 3.
In carrying out my invention I construct the motor car with wheels A A at each
side in centre, and with front wheel B and back wheel C.
Each of the said wheels B and C serves for both driving and steering, and is
mounted (by means of a suitable bracket 1) with spiral springs E) on a turntable
or pivot wheel F, which works in a fixed dished frame or casing G with a series
of antifriction rollers H thercon, (in Fig. 3 only one of these rollers is shown in
position).
The said casing G has a central sleeve or boss K, the turntable F being mounted
loosely on the said boss and being retained in position by a split collar L.
The spindle M, which is driven from the main driving shaft N by bevel gearing,
passes through and revolves within the said boss K, operating the pinion P by
means of the skew-cut wheels R and S, or by other suitable gearing.
The said pinion P operates the driving wheel by means of a chain T, and a
chain wheel U on the felloe (as shown applied to the back wheel C in Fig. 1), or,
by means of a pin wheel V and spur wheel W on the felloe, (as shown applied to
the front wheel B in Fig. 1).
The chain wheel U or spur wheel W on the felloe of the driving wheel may
be protected by a suitable mudguard.
The main driving shaft N, from which the front and back wheels B and C are
driven, is in two parts connected by differential gear X.
Upon preferably one half of each turntable F are teeth gearing with worms A
at each end of a diagonal shaft B, which is operated from the steering handle C¹
by bevel wheels D¹ and E', one of larger diameter than the other.
By this means the driving wheels B and C may be simultaneously turned in
opposite directions as required in steering (as shown by dotted lines in Fig. 2),
without interfering with the driving mechanism or causing any extra strain on the
said driving wheels.
The casings GG, carrying the steering gear, are bolted to a suitable steel
frame which is secured to the body of the car in any suitable manner.
The skew-wheels R R are preferably dished to give greater clearance and allow
for springing of the driving wheels.
My improved gear enables the car to be turned in any required radius, or
when the wheels B and C are in their extreme position (that is, at right angles to
the body of the car), it may be turned about its own centre without any forward
or backward movement.
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. In a motor car the combination, with a central wheel axle having loose side
wheels, of front and back driving wheels mounted on turntables or pivot wheels
so as to be turned independent of the driving mechanism, thereby enabling the
car to be turned in any required radius, substantially as shown and described.`
2. In a motor car with front and back driving wheels, the employment of a
diagonal steering shaft with worm gearing operating simultaneously the turntables
carrying the said driving wheels, the driving gear being worked independently
through or within the said turntables, substantially as shown and described.
3. In a motor car the combination of the fixed casing G, having a central
sleeve K, the central driving spindle M, the skew-gear wheels R and S (or like

page_text: mechanism), the pinion P, the toothed turntable F carrying the driving wheel
bracket 1), the antifriction rollers H, the split collar L, and the chain T with
chain wheel U (or equivalent device), all arranged and operated substantially as,
and for the purposes, shown and described.
