PROVISIONAL SPECIFICATION.
Improvements in or Applicable to Go-carts and other Two Wheeled
Vehicles.
I GEORGE YATE ASHWELL of 23 Barrowgate Road, Chiswick, Middlesex, Engineer
do hereby declare the nature of my said invention to be as follows:-
The object of this invention is to so arrange the shafts of this class of vehicle that
the two shafts (either singly or together) can be adjusted in height or angle with the
bo ly of the vehicle so as to suit the height of the child or person pushing or drawing
the vehicle and to keep the body in all cases parallel with the ground and my
improvements further relate to the application of an additional shaft or handle when
in the case of a go-cart the attendant walking along-side the vehicle can assist in its
propulsion whilst the child is between the shafts or two children of varying height
can each be accommodated with an adjustable shaft.
In performing my invention I either hinge or pivot the shaft to any convenient
part of the body of the vehicle and employ a quadrant toothed-rack ratchet wheel or
other mechanical equivalent for locking and securing the shafts at any angle or
I arrange the shafts to be capable of being raised by a screw operated say by a loose
or fixed winch handle. In some cases I apply an additional shaft or handle alongside
the existing fixed shafts and which can be adjusted to suit the height of the attendant
as aforesaid.
My improvements are equally applicable to two wheel vehicles drawn by
animals.

COMPLETE SPECIFICATION.
Improvements in or Applicable to Go-carts and other Two Wheeled
Vehicles.
I, GEORGE YATE ASHWELL of 23 Barrowgate Road, Chiswick, Middlesex, Engineer
do hereby declare the nature of my said 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 this invention is to so arrange the shafts of this class of vehicle that
the two shafts (either singly or together) can be adjusted in height or angle with the
body of the vehicle so as to suit the height of the chill or person pushing or drawing
the same and to keep the body of the vehicle more or less parallel with the
ground.
In performing my invention I either hinge or pivot the shafts to any convenient
part of the body of the vehicle and employ a quadrant toothed-rack, ratchet-wheel or
other mechanical equivalent for locking and securing the shafts at any angle or [
arrange the shafts to be capable of being raised by a screw operated say by a loose or
fixed winch bandle.
On the accompanying drawing Fig. 1 represents a side view of a go-cart embracing
my improvements.
a is the body of the vehicle mounted upon wheels b in the ordinary manner. The
shafts c instead of forming one piece with the framework or being otherwise secured
rigidly in position as heretofore are hinged or mounted upon horizontal axes d so as
to be capable of turning thereupon (as indicated in dotted lines) and thus of being
adjusted in angle with regard to the body of the go-cart as aforesaid.

page_text: And in order to affix the shafts in position at any desired angle I employ a segmental
clamping plate e upon the body of the vehicle as illustrated on an enlarged scale in
side view Fig. 2 and front view Fig. 3 which plate is capable of being tightened upon
the outside of the shaft c by a wing nut f screwing upon a holt . I prefer to have
a pin or peg projecting on the inner side of the shait to take into one of a series of
holes as shewn dotted in the enlarged views.
In Figs. 4 and 5 I illustrate a side and front view of another similar segmental
clamping device but with a series of side slots g formed in its clamping plate h for
grasping the stud i upon the shaft in an analogous manner to that employed in a
domestic shutter bar.
In Figs. 6 and 7 which illustrate similar views of another modification the clamping
plate kis hinged at the top and is secured by a spring catch 1.
Fig. & represents a side view of part of the body of a go-cart shewing how a
spring bolt m may be mounted upon the shaft n and be capable of securing the same
at any desired angle by forming a series of holes in a plate on the curved edge o of
the body of the go-cart to receive the point of the locking bolt m.
I have thus shewn several modifications of adjustable locking arrangements for
shafts mounted upon horizontal axes in accordance with my invention and I wish it
to be distinctly understood that I do not confine myself to the precise locking details
herein before described and illustrated on the accompanying drawing as it will be
obvious that the same may be considerably varied without departing from my
invention.
Having thus particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
Mounting the shafts of go-carts upon hinges or horizontal axes and fitting the same
with locking devices for adjusting the angle with regard to the body of the vehicle
substantially as and for the purposes hereinbefore described.
