PROVISIONAL SPECIFICATION.
Improved Construction of Tipping Trucks or Waggons.
We, ADRIEN HALLIER and EUGENE LETELLIER, both of No. 18, Rue Drouot,
Paris, France, Contractors, do hereby declare the nature of this invention to be as
follows:-
:-
Our invention relates to an improved construction of that description of trucks or
waggons for transporting materials in which the body is mounted on centres or
trunnions on a suitable underframing so as to be capable of being tipped to either
side for discharging its contents.
According to our improvements, instead of mounting the body on trunnions of
comparatively small dimensions, we fix or form on the ends of the same semi-
circular projections constituting half trunnions of large diameter by means of which
the body rests upon flat transverse bearers or rails carried by the underframing,
upon which these semicircular trunnions can roll to either side for discharging the
contents, and, on which the body is held in the upright middle position at other
times by means of suitable hooks or catches.
The body is guided in its rolling motion by means of upright pivotted guides on
the underframing having slots in which slide studs projecting from the semicircular
trunnions, as these roll to the one side or the other.
The transverse bearers or rails, on which the half trunnions roll, are by pre-
ference carried at a certain height above the underframing by means of angle iron
uprights fixed to each side of the ends of the latter, and middle uprights of trough
shaped cross section. To the transverse bearers are pivotted two hooks which
hook on to studs projecting from the half trunnion so as to hold the body in the
middle position.
The half trunnions are prevented from shifting out of this position otherwise than
by rolling, by forming at the middle of their undersides a V shaped tooth which
takes into a corresponding notch in the transverse bearer.
A guard plate is fixed against the end of the truck body above the half trunnion
for preventing the materials from falling on to latter on charging; the ends of this
guard plate also act as stops in coming in contact with the transverse bearer when
the body has been tilted over, and which, in imparting a shock to the body in
arresting its motion, insure the proper emptying thereof.

Improved Construction of Tipping Trucks or Waggons.
We, ADRIEN HALLIER, and EUGENE LETELLIER, both of No. 18 Rue Drouot,
Paris, France, Contractors, 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 invention relates to an improved construction of that description of trucks
or waggons for transporting materials in which the body is mounted on centres or
trunnions on a suitable underframing so as to be capable of being tipped to either
side for discharging its contents.
According to our improvements, instead of mounting the body on trunnions of
comparatively small dimensions, we fix or form on the ends of the same semi-
circular projections constituting half-trunnions of large diameter by means of which

page_text: the body rests upon flat transverse bearers or rails carried by the underframing,
upon which these semi-circular trunnions can roll to either side for discharging the
contents, and on which the body is held in the upright middle position at other
times by means of suitable hooks or catches.
The body is guided in its rolling motion by means of upright pivotted guides on
the under-framing having slots in which slide studs projecting from the semi-
circular trunnions as these roll to the one side or the other. -
The construction of the said improved tipping trucks will be readily understood
on reference to the accompanying drawings in which Fig. 1 shews an end view of
the truck, Fig. 2 a side elevation, and Fig. 3 a plan of the under-framing.
The under-framing A of the truck is constructed in the ordinary manner and
need therefore not be further described.
At each end it has fixed upon it a guide rail B, formed of a rectangular section
and secured at the ends to the under framing by angle iron uprights bb, and at the
middle by an upright e of a trough shaped section.
On these guide rails can roll arc shaped pieces C fixed to the end faces of the
body of the truck, and constituting half trunnions to this, while at the same time
they serve to control its rolling or tipping motion, by having at their middle a
bolt F which passes through a slot in a link E the lower end of which is pivotted
at e to the under framing.
g
The body is maintained in its vertical position by means of hooks G pivotted
at to the rail B, which hook on to studs g' fixed on the piece C. The proper
vertical position of the body is further insured by means of a V shaped projection
on the piece C which fits into a corresponding notch in the rail B.
A curved angle iron guard H prevents the material from falling on to and
obstructing the action of the above described parts when loading.
The ends of this guard also act as stops in coming in contact with the guide
rails B when the body has been tilted over, and which in thus causing a shock to
be imparted to the body in arresting its motion, insure the proper emptying
thereof.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
An improved construction of tipping trucks wherein the body is supported by arc
shaped pieces fixed to the ends thereof, consisting of large semi-circular trunnions
which can roll with the body upon transverse guide rails fixed on the ends of the
under framing, the body being guided in its tipping motion by slotted guides
piyotted to the under framing, into the slots of which take bolts or studs on the
arc shaped piece, while when the body is in the vertical position it is secured by
hooks pivotted to the guide rail, and by a projection on the arc shaped piece fitting
into a notch on the guide rail, substantially as described.
