Improvements in Apparatus for Tipping Wagons, Carts, and other
Vehicles.
I WILLIAM ROBERT HARRISON, of Newington Ironworks, Hull in the County
of York, Mechanical Engineer and Works Manager, do hereby declare the nature
of this invention to be as follows :-
These improvements have reference to the mode of tipping the bodies of wagons,
carts or other vehicles, and consist of one two or more rocking levers, or toggle
arms, working in bearings placed in a convenient position on the undercarriage of
a vehicle, the body of such vehicle being jointed to the extremities of the said
rocking levers or toggle arms, and bearing upon and acting in conjunction with a
cam or cams fixed upon the said undercarriage.
I construct my invention as follows:-I attach the body of the vehicle by
suitable joints and bearings or the like to the extremities of the rocking levers or
toggle arms, taking care that the position of these bearings is such, that that
portion of the body which is to the rear of the said bearings is much heavier than
the front portion and I carry the said levers or toggle arms, upon a suitable shaft
or bearings on the undercarriage. I also fix upon the aforesaid undercarriage a
cam or cams to support the rear end of the body, and to facilitate its action in
tipping, I also employ a combination of bevel wheels, worm and worm wheel, and
quadrant and pinion for heavy vehicles, (but for lighter vehicles other and less
gearing may be employed). The aforesaid gearing is actuated by a handle or
handwheel fixed on the front part of the said undercarriage or in any other
convenient position.
The action of tipping the body is as follows:-By turning the handle or hand-
wheel the aforesaid gearing is put into motion and in turn causes the weigh-bar
shaft to perform about one fourth of a revolution and by so doing the body is
elevated by means of the rocking levers or toggle arms, and as the portion of the
body which is behind the bearings is considerably heavier than the front portion,
the back part continues to rest upon the cam or cams placed at the rear end of the
undercarriage, and so eventually arrives at the necessary angle or inclination for
properly discharging its load, and by simply reversing the motion of the handle or
handwheel the body can be brought back to its original horizontal position, after
discharging its load or part of it.
With this improved construction of apparatus for tip wagons and the like, such
wagons can be fitted with springs of the ordinary shape and arrangement without
in any way interfering with tipping their bodies, also it allows the body to lock at
any angle when tipping, it being self locking, and at the same time makes the work
of tipping so easy that one man can tip a very heavy load.

SPECIFICATION.
Improvements in Apparatus for Tipping Wagons, Carts, and other
Vehicles.
I, WILLIAM ROBERT HARRISON of Newington Ironworks, Hull in the County
of York, Mechanical Engineer and Works Manager 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 :-
These improvements have reference to the mode of tipping the bodies of waggons,
carts or other vehicles, and consist of one, two or more rocking levers, or toggle
arms working in bearings placed in a convenient position on the undercarriage of a
vehicle. The body of such vehicle being jointed to the extremities of the said
rocking levers or toggle arms, and bearing upon and acting in conjunction with a
cam or cams fixed upon the said under-carriage.
I construct my invention as follows:- attach the body of the vehicle by
suitable joints and bearings or the like, to the extremities of the rocking levers or
toggle arms, taking care that the position of these bearings is such, that that
portion of the body which is to the rear of the said bearings, is much heavier than
the front portion, and I carry the said levers or toggle arms, upon a suitable shaft
or bearings on the under-carriage. I also fix upon the aforesaid undercarriage a
cam or cams to support the rear end of the body, and to facilitate its action in
tipping. I also employ a combination of worms and worm wheels, quadrant and
pinion for heavy vehicles but for lighter vehicles other and less gearing may be
employed. The aforesaid gearing is actuated by a handle or hand wheel fixed on
the front part of the said undercarriage or in any other convenient position.
The action of tipping the body is as follows:-
By turning the handle or hand wheel the aforesaid gearing is put into motion,
and in turn causes the weigh-bar shaft to perform about one fourth of a revolution,
and by so doing the body is elevated by means of the rocking levers or toggle
arms, and as the portion of the body which is behind the bearings, is considerably
heavier than the front portion, the back part moves upon the cam or cams placed
at the rear end of the under-carriage and so eventually arrives at the necessary
angle or inclination for properly discharging its load, and by simply reversing the
motion of the handle or hand wheel, the body can be brought back to its original
horizontal position, after discharging its load or part of it.
With this improved construction of apparatus for tip waggons and the like, such
waggons can be fitted with springs of the ordinary shape and arrangement, without
in any way interfering with their full action and deflection, also it allows the body
to lock at any angle when tipping, it being self-locking, and at the same time
makes the work of tipping so easy that one man can tip a very heavy load.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a front elevation of tipping waggon with my improvements applied.
Fig. 2. is a plan of bottom of tipping waggon.
Fig. 3. is a slight modification of Fig. 1 showing body of van of iron made
watertight with extended rack quadrant.
A is a weigh bar shaft carried in block bearings A', attached to the longitudinal
timbers of the under-carriage C, B is a lighter shaft also carried in block
bearings B', but which are attached to the soles B' or chests of the body of the
van, C is a cross shaft working in bearings on the under-carriage, and carrying the
rack pinion H, also the worm wheel D into which works the worm D', E is another
worn wheel, and E¹ the worm gearing into it. E and E³ are spindles for the
worm and worm wheels for operating the pinion and quadrant rack. F are
malicable iron cams placed on the outer timbers of the undercarriage, and upon

page_text: which the body works by means of the rubbing plates J, or by friction rollers
if preferred, the cams also forming the end bearings or shoes J', for the back
springs J, and also (if required) the outer bearings of the weigh bar shaft A.
It will readily be seen that by actuating the first motion spindle E³ by an
ordinary loose crank handle, motion is imparted by the worms and worm wheels to
the rack pinion H, which in turn operates the quadrant G, fixed upon the weigh
bar shaft A, upon which weigh bar shaft are also keyed the outside levers L L',
(which are jointed to the shaft B) thus elevating the front end of body of the
back end (being the heaviest) rests upon the cams, and working back upon them
until the necessary angle is obtained for discharging its load, after which, the body
can be brought back to its original horizontal position, by simply reversing the
motion of the crank handle, the shaft B acts as a pivot for the levers L L.
van,
One very great advantage obtained by this lever and cam tipping arrangement,
that these vans or waggons can be fitted with springs of the ordinary shape and
arrangement, without in any way interfering with the tipping of their bodies, and
yet permitting of the full action and deflection of the springs, it also makes the
body self-locking in any position, the gear is also extremely powerful, and by
means of it, one man can discharge a load of two or three tons with ease, and it
also posseses this advantage, that a vertical tip can be obtained when required, so
that the body can be made in box shape if necessary (in either iron or wood) with
a fixed sloping back end see Fig. 3 perfectly water-tight for a portion of its depth,
but yet allowing the load to be completely discharged by the large range of this
tipping gear.
The immense advantage of a perfectly watertight body for con-
veying night-soil and the like entirely covered over, and yet capable of being
completely discharged at one operation, cannot be overestimated, especially where
the night-soil contains a large proportion of liquid matter, and has to be conveyed
through the streets of a town, in very hot weather, or during an epidemic, such as
cholera and the like.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The construction of waggons, vans or the like vehicles having a tipping
motion, by means of a combination of cams and rocking levers, substantially as
shown and described.
2. Tipping waggons (with ordinary springs) constructed so that they can be
tilted or tipped by hand to any angle, and locked at any point by means of worm
gearing, as and for the purposes such as shown and described.
3. The combination of the quadrant G upon weigh bar shaft A, pinion upon
shaft C, levers L, L, shaft B, worms E' and D', worm wheels E and D, with
spindles E and E³, with or without the cam F, and plate J, substantially as shown
and described.
