Improvements in Self-propelled or Motor Vehicles for Common
Roads.
I, WILLIAM PECK, of the City Observatory, Calton Hill, Edinburgh, Scotland,
Director of the Madelvic Motor Carriage Company Limited, 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:-
My invention has for its object to provide a compact and convenient arrange-
ment of self propelling or motor vehicle for common roads, wherein the motor
and front wheel and their attachments are carried by an under frame the front
wheel constituting the driving and steering wheel of the vehicle the steering
being effected by turning the under frame and front wheel to the requisite angle
to a frame which carries the body of the vehicle the last named frame being
connected to the under frame by being attached to a pivot over the front driving
and steering wheel. The frames are provided with engaging parts which allow
of the relative movement of the frames and parts carried thereby in steering
but secure rigidity lengthwise of the vehicle in all positions of the parts and
to further secure this rigidity a pinion or pinions on the under carriage may
engage with teeth on an are or ares carried by the frame of the body of the
vehicle. I will describe an arrangement according to my invention with refer-
ence to the accompanying drawing Figure 1 of which is a side elevation and
Figure 2 a plan with the carriage body removed. Figure 3 is a cross section
on the line 1, 2 Figure 2.
on
The main body A of the carriage is supported on a frame B which is suspended
on springs C, carried by the axle of the rear wheels D. The front of the said
frame B is supported upon a pivot b which forms the centre of steering motion
of the front wheel E which is both the driving wheel and the steering wheel it
being mounted upon a lower frame work F which carries the motor. The said
pivot bis continued by a fork h which carries the bearings for the axle of the
front wheel. The framework B is provided with arcs 62 63 forming segments of
circles struck from the centre b on which the front. wheel turns in steering. An
are f on the framework F engages as shewn in cross section with the arc
the framework B. The ares 2 are provided with teeth with which engage
pinions carried by the lower framework F so that when the said framework F
is moved by the lever g in steering the pinions g² g³ run along the teeth of the
arcs 23 and the are f runs along the are 3 by reason of its engagement there-
with as shewn in Figure 3. The lever g is connected to the frame F by a pin
& slot connection f & is fast on the lower end of a spindle which is carried
in suitable supports in the frame B & provided at its upper end with a handle g³
by means of which the spindle can be turned in its supports and so cause the
frame to turn on its centre to any desired angle to steer the vehicle in the
direction required. By the construction described the rigidity of the vehicle as
a whole is preserved in all positions.

page_text: I may use only the arcs b and f if desired or I may use two or more arcs (with
engaging pinions) all struck from the same centre and in place of the arc f
any other engaging device may be used.
Having now particularly described and ascertained the nature of this in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. A self propelled or motor vehicle having a body part mounted upon wheels
at the rear and connected at front to a pivot carried by an under frame which
carries the motor and front steering and driving wheel and means for securing
the rigidity of the whole in all positions substantially as hereinbefore described.
2. The arrangement and combination of parts constituting a self propelled
or motor vehicle substantially as hereinbefore described and shewn in the
accompanying drawing.
