I CHARLES FAULKNER HART, 26 Lanvanor Road, Queens Road, Peckham,
Sarry Journeyman Coachmaker. do hereby declare the nature of my invention
for ENABLING THE DRIVER OF A TWO WHEELED CAB TO ADJUST THE BALAnce of
THE VEHICLE to be as follows:-
The span Iron which carries the back end of the springs fixed to a stay under
the drivers seat is made to slide in a grooved frame, through means of a pin with
a screw on the centre which runs through a nut in the span Iron, a mitre cog
wheel is fixed on the end of this pin next the body, a rod with a handle runs from
the roof of the Cab through the drivers foot board with a mitre cog wheel on the
end to fit in the mitre cog wheel, on the pin, when the handle is turned the pin
with the screw revolves and causes the span Iron to slide either way, taking with
it the axle & wheels at the will of the driver.

I, CHARLES FAULKNER HART of 26 Lanvanor Road, Queens Road, Peckham
Surrey, Journeyman Coachmaker do hereby declare the nature of my Invention
and the manner in which the same is to be performed as follows:-
The object of this Invention is to provide simple, effective, and reliable means of
adjusting the weight of a two wheeled Cab with its load in such a manner that it
may be easily balanced on its axle by the driver whenever required such as when
the load is greater on one side of the axle than on the other, also when the vehicle
is going up or down hill, the horse being thus relieved from the weight of the
Cab and having only the work of pulling the Cab to perform.
By the
present Invention this object is attained without any alteration in the ordinary
construction of two wheeled Cabs being necessary.
My Invention will be clearly understood by the following description with the
aid of the annexed Drawings in which Figure 1 is a side elevation of a two wheeled
Cab with my adjusting apparatus shown attached, and Figure 2 is a view as seen
from the back of the vehicle. Figure 3 is a perspective view of the apparatus
detached, and Figures 4 and 5 represent the inner and outer frames respectively of
Figure 3 as they would appear if taken apart. The same reference letters refer to
the same parts in all the Figures.
According to my Invention I fit within reach of the driver a handle or hand
wheel A attached to a rod B (Figures 1 and 2) which passes down the side of the
driver's seat and carries at its lower end a small mitre cog wheel O gearing into
another similar mitre wheel D keyed on a screw E. This screw E is carried by a
rectangular frame F, preferably of malleable iron, firmly attached by clips or other
suitable means to the stay a under the driver's seat and to stays from the back of
the Cab. The frame F has grooves G G (Figures 4 and 5) on two of its inner sides
which serve as guides and supports for an inner frame H which slides to and fro in
the said grooves G G. At the end of the inner frame H nearest the body of the
Cab is a screw threaded hole or nut I through which passes the screw E on the
outer frame F and the other end of the inner frame H forms a block J which
(when my apparatus is to be fitted to a ready built Cab) is firmly attached by
clips bor otherwise to the centre of the dumb bar or span iron K which carries
the two back ends of the springs L L
The action of the apparatus is as follows:-When the driver finds that the Cab
is unevenly balanced through the extra weight of the passengers or of the driver
himself, or on going uphill or downhill, be turns the handle or handwheel A in one
or other direction according as to whether the load is too much in front or too
much behind, this causes the screw E to revolve and forces the inner frame H to
slide backwards or forwards in the grooves G G of the outer fixed frame F taking
with it the dumb bar or span iron K and as this span iron carries the ends of the
springs L L fixed to the axle, the wheels, axle, and springs will be moved a little
backward (as shown in dotted lines Figure 1) or forward as the case may be with-
out moving the body of the Cab itself thus restoring the equilibrium of the vehicle

unnecessary strain.
The hanging irons M on which the front of the Cab is suspended are pivot
jointed to allow a certain amount of play to the springs. This may be effected by
hanging the front end of the springs L on a pin passed through an eye on the end
of the hanging iron M as shown in the Drawing, Figure 1.
My Invention is applicable to two wheeled Cabs of any construction or form,
and where the driver's seat is in front of the vehicle it is obvious the apparatus
can be modified to act from the front instead of the rear without departing from
the principle of the Invention. The detail parts are also capable of variation in
form and arrangement.
Having now particularly described and ascertained the nature of the said
Invention and the manner in which the same is to be performed, I declare that
what I claim is :-
The improved apparatus for adjusting the balance of two wheeled Cabs
consisting of a fixed frame and a sliding frame connected by means of the span
iron to two ends of the springs and actuated by suitable gear from the driver's
seat, substantially as described and as shown in the annexed Drawings.
