PROVISIONAL SPECIFICATION left by the said Charles Hill at the Office
of the Commissioners of Patents on the 10th April 1883.
CHARLES HILL of Shard Square Peckham Park Road in the County of Surrey,
"IMPROVEMENTS IN APPARATUS FOR TIPPING VANS AND OTHER VEHICLES"
This invention relates to improvements in apparatus for tipping the bodies of
vaus wagons trucks and other vehicles in order to discharge the contents thereof.
For this purpose a lever is arranged on one side of the van truck or other
vehicle to be tipped which lever on being actuated or pulled over acts to unlock or
release the tail-board of the van.
The lever acts on a crank or lever which forces a spring and lifts another crank
or lever thus raising a latch to unlock and open the tail-board.
.'
The body of the van by this means becomes entirely free and by a slight touch
will tilt up leaving the tail-board suspended thus allowing the contents of the van
or truck to be discharged

"IMPROVEMENTS IN APPARATUS FOR TIPPING VANS AND OTHER VEHICLES
"
This Invention relates to improvements in apparatus for tipping the bodies of
vans wagons trucks and other vehicles in order to discharge the contents thereof.
For this purpose a lever is arranged on one side of the van truck or other
vehicle to be tipped which lever on being actuated or pulled over acts to unlock or
release the tail-board of the van.
The lever acts on a crank or lever which forces a spring and lifts another crank
or lever thus raising a latch to unlock and open the tail-board.
The body of the van by this means becomes entirely free and by a slight touch
will tilt up leaving the tail-board suspended thus allowing the contents of the van
or truck to be discharged.
And in order that my Invention may be clearly understood and readily carried
into practice I will proceed to describe the drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS
1
1
Figure 1 shows a side elevation of the apparatus in position when the wagon
body is loaded and locked ready for use. Figure 2 is a similar side elevation of 2
the apparatus in the position when the wagon body is unlocked and ready to be
tilted to discharge the contents. Figure 3 is a back elevation of the wagon body
showing the apparatus for securing the tail board. Figures 4 and 5 show two
views of the wagon on a smaller scale. Figure 4 shows the wagon body in its loaded
position, Figure 5 shows the body tilted and in the position when the load is being
discharged.
aa is the frame on which the apparatus is carried. a¹ is a lug to which is
jointed the handle b which by a link c is connected to a lover & turning on a fixed
shaft e carried by the frame a connected to the lever dis a slide f to which one
end of a lever g is jointed at f¹ the other end of the lever g is connected by a link h
to a lever i the other end of which is pin jointed to the standard k carried by the
frame a. At the upper end of the standard is a fixed pin on which the tail-
board of the wagon is hung in the way shown by the drawings. m is a small
standard to which is jointed the lever n which acts on the latch lever for securing
the tail board the lever n is also jointed to the lever g at the point g¹. o is a small
lever carried by the axis e and connected by a rod p to a latch lever q for securing
the fore end of the wagon body to the frame. is the main axis in which the
body of the wagon is carried and turns when tilted.
The action of the apparatus is as follows; in pulling the lever handle 6 in the
direction of the arrow from the position shown in Figure 1 into the position shown
at Figure 2 the lever d by means of the link c turns on its shaft e drawing back
the slide fand turning the lever g on its centre g' thereby-pushing the upper end
of the lever g back and by the action of the link and lever i opening the tail-
board an arm from which rests against the lever i. In order to unlatch the
tail-board before it is caused to swing back one end of the lever n is curved as
shown and passes under the latch levers u. When the slide is drawn back the
lever g turning on its centre g¹ lifts the lever n thereby freeing the latch levers
from their catches u¹ u. The latch levers are made in two parts and pin jointed

page_text: together at the point u³ each of which turns on a centre u³ carried by the tail-
board a, u³ is a descending part or limb which also acts to secure the tail-board.
u is a spring to hold the latch levers in position. At the same time that the tail-
board is pushed back the cart body is unlatched from the frame by the action of
the rod p pushing back the latch lever q and freeing it from the catches q¹ carried
by the frame a similar apparatus is arranged on both sides of the waggon with the
exception of the handle b and link c. The parts on the opposite side being actuated
by the shaft e.
Having thus described the nature of my Invention and the manner of performing
or carrying the same into practice I would remark that I do not limit myself to the
precise details herein before described so long as the novel features of my Invention
are retained at the same time I make no claim to any of the mechanical parts
separately which are well known and in common use But what I claim is:-
The improved arrangement and combination of apparatus for tipping the bodies
of vans and other vehicles arranged to act substantially in the manner and for the
purpose herein before fully described and represented in the drawings hereto
annexed.
In witness whereof I the said Charles Hill have hereunto set my hand and scal
this ninth day of October in the year of our Lord One thousand eight hundred and
eighty three.
