PROVISIONAL SPECIFICATION.
Improved Means for Fixing the Shafts to Tip Carts and like
Vehicles.
I, ROBERT COOK, of Whitletts, near Ayr, Ayrshire, N.B., Joiner and Cart-
wright, do hereby declare the nature of this invention to be as follows:-
This invention is for locking and firmly fixing the shafts of coup or tip carts to
framing of cart, and to prevent vibration and consequent friction between shafts
and body of cart.
This invention consists of a spindle of iron or steel, which is passed through the
side framing of cart from side to side, its position being underneath the bottom of
cart and immediately above the shafts on which it is intended to act.
At one end of the spindle is a handle to turn it, and ratchet to prevent it turning
back, and at the other end is a screw, the nut of screw being fixed in the side
framing of cart.
At respective distances and immediately above the shafts, two cone shaped pieces
of iron or steel (hereafter termed cones), are fixed on to spindle and concentric with
spindle. Two bushes are also fixed to shafts, to receive these cones, so that when
handle is turned the spindle and cones advance by the action of the screw, cones
entering into bushes and by their taper acting like a wedge drawing up shafts and
jamming them to body of cart.
When handle is turned backwards cones are drawn out of bushes and shafts are
released and cart allowed to tip up, the spindle passing up out of bushes through a
slot in top of bushes.

COMPLETE SPECIFICATION.
Improved Means for Fixing the Shafts to Tip Carts and like
Vehicles.
I, ROBERT COOK, of Whitletts, near Ayr, Ayrshire, N.B., Joiner and Cart-
wright, 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 is for locking and firmly fixing the shafts of coup or tip carts, to
framing of cart, and to prevent vibration, and consequent friction, between shafts
and body of cart.
This invention consists of a spindle of iron or steel, which is passed through the
side framing of cart from side to side, its position being underneath the bottom of
cart and immediately above the shafts on which it is intended to act.
At one end of the spindle is a handle to turn it and a ratchet to prevent it from
turning back, and at the other end is a screw the nut of screw being fixed in the
side framing of cart.
At respective distances and above the shafts two cone-shaped pieces of iron or
steel (hereafter termed cones) are fixed on to spindle and concentric with spindie.
Two bushes are also fixed to shafts to receive these cones, so that when handle is
turned the spindle and cones advance by the action of the screw, cones entering into
bushes and by their taper acting like a wedge drawing up shafts, and jamming them
to body of cart.
When handle is turned backwards cones are drawn out of bushes, and shafts are

page_text: released, and cart allowed to tip up, the spindle passing up out of bushes through a
slot in top of bushes.
These bushes must be so fixed to shafts that the point of cone touches top of
bush as soon as it enters, otherwise the taper is lost for drawing up shafts.
And in order that this invention may be better understood I will now describe
the drawings annexed.
Fig. 1. is a plan of spindle ready to be placed in position.
Fig. 2 is an elevation of one of the bushes showing slot at top, and bolt and nail
holes for fixing bush to shaft.
Fig. 3 is a plan of part of the framing of cart with invention in position, with
nut at one end and wheel with notched rim, (in preference to handle and ratchet)
at the other end.
Fig. 4. is a sectional elevation with part of front bar removed to show invention,
particularly the suspension of the shafts.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it to be understood
that I make no claim to any of the seperate mechanical parts, nor do I confine
myself to the details shown and described, as I am fully aware that there are
various methods of causing cones to act, such as dispensing with the screw and
pushing forward spindle by means of a lever, or a spring, or simply by the hand, in
which cases spindle need not revolve nor taper pieces be conical in shape. Another
method which I shall describe is by fixing pieces excentric to spindle, and drawing
up shafts by a half turn of spindle. But I declare that what I claim is
First. The method or methods of fixing shafts herein shown and described.
2nd. The application of a slotted bush allowing spindle to pass up through slot.
3rd. The application of a taper conical or otherwise, to a slotted bush for the
purpose shown and described.
