page_text: Improvements in or relating to Carts or Lorries.
I, ROBERT TURTON, of 53, Upper Diccinson Street, Wigan, in the County of
Lancaster, Wheelwright, do hereby declare the nature of this invention to be
as follows:-
1
Hitherto four-wheeled carts or lorries have not been arranged to tip, and con-
sequently the goods with which they were loaded had to be lifted off by manual
labour or by machinery, often a laborious operation. The present invention is
designed to provide a four-wheeled cart or lorry with a tipping arrangement so
that the goods laden thereon can be tipped off instead of lifted or shovelled off.
In carrying the invention into effect, I form my cart or lorry with a body
and under-carriage. The body is adapted to slide or roll longitudinally along
the under-carriage, the former being provided with rollers to facilitate this
being effected, so that when it has travelled about half the length of the under-
carriage, it will tip into a diagonal position and precipitate the goods onto the
ground. There are several ways in which the body can be moved. In one
arrangement I provide an endless chain passing over guide rollers or sprocket
wheels. In the links of this chain a projection from the body engages, so that
by operating the chain by means of a handle on one of the sprocket wheel
spindles, the body will be travelled along the under-carriage.
Instead of a chain however, a longitudinal worm may be provided screwing
through a nut on the body so that by turning the screw by a handle the body
will be travelled back or forth. The nut or the projection which engages in the
links may be hinged to the body, so that when it tips into an oblique position,
this hinge acts as the pivot on which the body turns. The nut cannot tip with
it but being hinged will remain in its normal position on the screw. An anchoring
arrangement or other suitable device can be provided for preventing the body
sliding or rolling completely off the under-carriage.
To tip the body into an oblique position, the handle is rotated which travels
the chain or rotates the worm as the case may be. This moves the body longi-
tudinally, until half (more or less) overhangs the end of the under-carriage,
when the weight will cause the body to tip into an oblique position, the hinge
acting as a pivot on which the body turns, or other suitable arrangement of
pivot may be provided. To return the body into a horizontal position, the screw
(or the chain) is worked in the reverse direction, and the body resumes its normal
position in which it can be locked, so that it cannot be accidentally moved.

page_text: I, ROBERT TURTON, of 53, Upper Diccinson Street, Wigan, in the County of
Lancaster Wheelwright, 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:-
-
Hitherto four-wheeled carts or lorries have not been arranged to tip, and con-
sequently the goods with which they were loaded had to be lifted off by manual
labour or by machinery, often a laborious operation.. The present invention is
designed to provide carts or lorries of the aforesaid type with a tipping arrange-
ment so that the goods laden thereon can be tipped off instead of lifted or
shovelled off.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which:-
Figure 1 is a sectional elevation of a lorry with my invention applied thereto;
Figure 2 a plan with the body part removed;
Figure 3 a plan of the body viewed from the underside;
Figure 4 a transverse section of Figure 1;
Figure 5 a diagrammatic view showing the mechanism for sliding the body
part of the lorry;
Figure 6 an end view of the projection or link.
The
I form my cart or lorry with a body A and an under carriage B.
body A is adapted to slide or roll longitudinally along the under carriage B, for
which purpose the under carriage is provided with anti-friction rollers. To
facilitate this being effected, races or ways are provided on the under side of
the body which rest on the rollers, and they are by preference vee-grooved so
that the anti-friction rollers engage therein, and while facilitating longitudinal
movement absolutely resist any movement laterally of the body. Arms D) pro-
jecting vertically from the body A also resist side play. On the under side of
the body A, I provide a stop bar E, and at the extreme rear end of the under
carriage I provide a stop plate F. Thus when the stop bar E comes in contact
with the stop plate F, any further longitudinal movement of the body part is
stopped and prevented from sliding or rolling completely off the carriage. The
stop plate will hold the stop bar like a trunnion so that the body will tip into a
diagonal position and precipitate the goods on to the ground, as shown by dotted
lines in Figure 1.
There are several ways in which the body can be moved longitudinally so as
to tip it. In one arrangement I provide an endless chain G passing over guide
rollers or sprocket. wheels H. In the links of this chain a projection from the
body can engage, so that by operating the chain by means of a handle on one
of the sprocket wheel spindles, the body will be travelled along the under car-
riage. I is this projection or a link coupled at one end to the chain and at
the other secured to one end of the rod J, which rod is guided and retained in
a horizontal position by guides K in which arms engage. The rod has an
upward arm L at the opposite end which engages the body at the front end.
The sprocket wheel H of the endless chain is rotated by means of a handle M
through shaft N and gear wheels O. P is a kecker or lock bar adapted to
engage in an eyelet Q on the upward arm L and lock it and so prevent it and
the body accidentally moving back. Instead of a chain, however, a longitudinal
worm may be provided screwing through a nut on the body, so that by turning
the screw by a handle the body will be moved back and forth. The stop bar E
acts as a trunnion on which the body tips. The nut however cannot tip with it,

page_text: but the screw being hinged the nut will remain in its normal position on one
part of the screw. F. The stop plate prevents the body sliding or rolling com-
pletely off the under carriage.
To tip the body into an oblique position, the kecker bar P is withdrawn so
as to unlock the upward arm L. The turning of the handle M will then put
the chain into motion and cause the body to move longitudinally until half.
more or less, overhangs the end of the under carriage, and the stop bar E
engages in the stop plate F. The weight will then cause the body to tip into
an oblique position, as shown by the dotted lines, the stop bar E and stop plate F
acting as a hinge or trunnion on which the body turns, or other suitable arrange-
ment of hinge may be provided. To return the body into the horizontal posi-
tion, the screw or chain is worked in the reverse direction, and the body resumes
its normal position, in which it can be locked by the kecker bar, so that it cannot
be accidentally moved. It is obvious that the vehicle and its mechanism may
be arranged, if desired, to tilt sideways instead of at the rear end so as to dis-
charge its load over the wheels.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. The improvement in lorries or the like which consists in arranging the
body part so that it will slide on the under carriage either to the rear or to one
side and there overbalance and tip out the load.
2. A wagon, lorry or the like, comprising an under carriage, a body part or
platform mounted so as to slide or roll thereon, a stop bar or its equivalent
secured to one part and a stop plate secured to the other part in such a manner
as to limit the travel of the body and also to act as a trunnion on which the
body will turn when moved into position for overbalancing and so tip out the
load, and means for sliding or rolling said body or platform into position for it
to overbalance for tipping purposes, or to return it to its normal position when
the tipping operation is completed, substantially as described.
3. In a wagon, lorry or the like having an under carriage and a body part
adapted to slide or roll thereon, the mechanism for travelling or rolling the
body part into position for it to overbalance for tipping purposes, or for return-
ing it into and locking it in its normal position after the tipping operation is
completed, substantially as described.
4. The tipping wagon or lorry, constructed, arranged and operating substan-
tially as herein before described with reference to and shewn in the drawings
annexed.
