We DAVID GREIG, RICHARD HOLGATE SHAW and HENRY CHARLES DUBURGUET
Engineers, of the Steam Plough Works, Leeds, do hereby declare the nature of this
Invention to be as follows:-
Our object in this invention is to obtain in wagons that tip sidewise a greater angle
of tip on the box without unduly increasing the height of the wagon.
The wagon body or box we support near each of its ends upon two longitudinal
axes fixed below it, at a suitable distance apart on each side of the longitudinal centre
line of the wagon.
When travelling on the road the body of the wagon is carried securely upon the
two bearings at each end-when it is to be tipped it can be tipped to either side by
turning it on the axis which is on that side of the centre. The tipping may be done
by hand or by the pull of the engine acting on suitable chains coupled to the tipping
box. The above construction is especially applicable for wagons to be used on roads
and drawn by traction engines or animal power. For railway tipping wagons we
carry the wagon body or box by projections at its two ends resting in bearings at the
top of uprights which stand up from the base of the wagon.
The projections and the bearings in which they rest we make of such a form that
when the wagon is travelling the body or box is at each end, resting on two supports
at a short distance apart one on eitlier side of the central line. Outside these inner
supports are other outer supports. When the body or box is to be tipped to either
side the first part of the tipping motion takes place around one or other of the
inner supports the body or box not only turning around the support but also
sliding somewhat sidewise over it. Afterwards the motion takes place around the
outer support and the box is tilted further over till the tipping operation is completed.

We, DAVID GREIG, RICHARD HOLGATE SHAW and HENRY CHARLES DUBURGUET
Engineers, of the Steam Plough Works, Leeds, 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:—
Our object in this invention is to obtain in wagons that tip sidewise a greater
angle of tip on the box without unduly increasing the height of the wagon.
Figure 1 is a side elevation and Figure 2 is an end elevation of a wagon
constructed according to our invention and adapted to be used with traction engines.
The wagon body or box a we support near each of its ends upon two short longi-
tudinal axes b fixed below it, at a suitable distance apart on each side of the
longitudinal centre line of the wagon.
The under frame c of the wagon is carried on the wheels d d and in connection
with the fore wheels there is ordinary locking gear. On the underframe there are
U form bearings e e into which the short axes bb are received.
When travelling on the road the body of the wagon is carried securely upon
the two bearings at each end-when it is to be tipped it can be tipped to either
sido by turning it on the axis which is on that side of the centre. The tipping
may be done by hand or by the pull of the engine acting on suitable chains
coupled to the tipping box. The above construction is especially applicable for
wagons to be used on roads and drawn by traction engines or animal power.
For railway tipping wagons we carry the wagon body or box by projections at its
two ends resting in bearings at the top of uprights which stand up from the base of
the wagon.
Figure 3 is a side elevation and
Figure 4 is an end elevation of a railway tipping wagon constructed according to
this part of our invention.
fis the base or underframe of the wagon, it is supported from the wheels g g by
springs h h.
i is the body of the wagon, the projections by which it is carried and k¹ k² are
the bearings receiving these projections. "17 are the uprights of the base to which
the bearings are fixed.
The projections and the bearings in which they rest we make of such a form that
when the wagon is travelling the body or box is at each end, resting on two supports
at a short distance apart one on either side of the central line. Outside these inner
supports are other outer supports. When the wagon is travelling the inner or
concave part of each projection rests upon the inner or convex part of each
bearing. When to empty the wagon the body or box is to be tipped to either side
the first part of the tipping motion takes place around one or other of the inner
supports the body or hox not only turning around the support but also sliding some-
what sidewise over it. Afterwards the motion takes place around the outer support
and the box is tilted further over till the tipping operation is completed.

page_text: The outer part of each projection is as will be seen cylindrical and during the
tipping it travels down into the corresponding receptacle on the outer side of the
bearing. The advantages of this construction are that when travelling the body is in
a very stable position; yet when started it is readily tipped and it then turns through
a large angle.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
--
1. A tipping wagon having the box or body supported near each of its ends upon
two axes b which are received into two corresponding bearings e e on the base or
underframe substantially as described.
2. A tipping wagon having the box or body supported at its ends by projections ?³
and and bearings k¹ and k² substantially as described.
