1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester both in
the County of Lancaster. and 323, High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows :-
The invention relates to tip wagons or trucks or other like vehicles, and has more
especially for its object to facilitate the tipping or unloading of such trucks, wagons,
skips, tubs or the like.
In carrying out the invention, a device constructed of iron, steel or other suit-
able material, is attached to each end or side of the body of the truck or other
vehicle in such manner as to support the same. Each device is of a proper curve
to turn or roll upon a rail which is made of iron, steel or other suitable material,
and so designed and constructed that the device aforesaid may turn or roll upon it,
so as to enable the body of the truck or other vehicle to rotate to or assume a
proper position for tipping its load or contents. The said device is affixed to the
body of the truck or other vehicle; and each rail is mounted on or may form a part
of a standard upon the frame or carriage of the truck or other vehicle. Suitable
geared teeth may be provided to prevent the device from slipping or skidding on
the rail while turning thereon, but other means may be adopted to secure that end.
Such geared teeth inay form integral parts of the device and of the rail, or be
attached to them or either of them.
A seat or flattened portion is provided near the middle of the device to permit of
the body of the truck or other vehicle sitting or resting steady in the running
position. A rounded tooth or projection upon the rail enters a corresponding
indentation in the device and serves to steady the truck body when in that position.
Some of the advantages of this device over the methods heretofore or at present
in use for attainment of the object desired, are:-
1. Greater ease in handling, by which less labour or force is necessary in throwing
the vehicle over into tipping position and in controlling the emptying of the
contents gradually or otherwise.
2. By suitable modifications of the design or pattern of the device, the tipping
position may be regulated or fixed to suit the work.
3. The device satisfactorily secures delivery of the load clear of the body of the
carriage or frame of the truck or vehicle to which it is applied.
4. The action of the device being smooth and free from any jar or shock, damage
to its parts or to the vehicle (to which it is applied) in the motions of unloading, is
greatly reduced, and the wear and tear thereof diminished.
5. The device may be made in castings to pattern, thereby securing economy in
first furnishing, and in after replacing of parts.
6. The device is simple and not liable to get out of order, there being no loose
parts required in it.
7. The device made in suitable dimensions is applicable to large or small trucks
and other vehicles with which such a tipping action is required, and can be cheaply
and efficiently applied also to those of other patterns of vehicle at present in use.

Improvements in or Appertaining to Tip-wagons, Trucks, Skips,
or other like Vehicles Adapted to be Emptied by Tipping.
A communication from abroad by WILLIAM CHARLES CHITTY ERSKINE of Kimberley,
in the Territory of Griqualand West, in the Colony of the Cape of Good Hope,
Inspector of Mines.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool & 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
Engineer, 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 :-
The invention relates to tip wagons or trucks or other like vehicles, and has
more especially for its object to facilitate the tipping or unloading of trucks,
wagons, skips, tubs or other vehicles.
The invention is best described by aid of the accompanying drawing, which
depicts, as an example, an end elevation, in outline, of a tipping truck constructed
in accordance with the invention, the dotted lines showing the position of the body
of the truck when it is tipped for emptying on either side.
In this
-
A, is the body of the truck, B the frame or carriage, (upright mounted at or in
proximity to each end of the frame, D a trunnion attached to each of two opposite
ends of the body A and adapted to support it on the upright C aforesaid. The said
trunnions are of a crescent or segmental shape, having a suitably curved periphery,
and so designed or constructed that the body is capable of being rocked or moved
upon the top of the support aforesaid, or on a rail or toothed rack (curved or
straight) mounted thereon, in such a way as to tip or discharge its contents over
the sides, clear of the rails e, as shown by the dotted lines on the drawing.
The said trunnions are preferably provided with teeth which engage the teeth of
racks E, adapted to prevent the trunnions from slipping or skidding on the upright
while the body is being tipped, but other means may be adopted to secure that end.
Such geared teeth may form integral parts of the trunnion, and of the rail, as shown,
or be attached to them, or either of them.
A seat or semi-circular cavity F may be provided near the middle of each of
the trunnions D, which receives a stop or projection of corresponding shape upon
the upright C. These serve to steady the body while the truck is moving. If
desired, the segmental trunnion might be affixed to the supporting frame, and the
rail or toothed rack to the body. The result would he practically the same.
The drawing accompanying this specification depicts one form of truck constructed
in accordance with the invention for tipping its contents at the side, but it will
be readily understood that, if the body A is supported at the sides, it can be adapted
to tip the load at either end.
Some of the advantages of this invention over the methods heretofore in use for
attainment of the object desired are:-
1. Greater ease in handling, by which less labour or force is necessary in
throwing the body over into tipping position and in controlling the emptying of the
contents gradually or otherwise.
2. By suitable modifications of the design or pattern, the tipping position may be
regulated or fixed to suit the work.
3. It satisfactorily empties the load clear of the frame of the truck and of the
rails on which the vehicle runs.
4. The action being smooth, and free from any jar or shock, damage to the parts
or to the vehicle in the motions of unloading is greatly reduced, and the wear and
tear thereof diminished.
5. The trunnion may be made in castings to pattern, thereby securing economy in

page_text: first furnishing, and in after replacing of parts. Further, it is simple and not liable
to get out of order, there being no loose parts required in it.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. A tip wagon, truck, skip, or other like vehicle, in which a segmental trunnion D,
having a suitably curved periphery with or without teeth, is affixed to each of two
opposite sides of the tip body (or supporting frame) of the vehicle, and adapted to
engage a suitably shaped rail or toothed rack E on the said supporting frame (or tip
body), whereby the said body is rendered capable of being so turned over or rocked
that its contents can be discharged clear of the under frame of the vehicle,
substantially as described.
2. The combination with a tip wagon, truck, skip, or other like vehicle, of a
trunnion D affixed to the tip body (or supporting frame) of the vehicle, and having
teeth on its peripheral surface, and also a seat or cavity F, and of a toothed rack E
adapted to engage the teeth aforesaid and prevent the said trunnions from slipping
or skidding when the body is being tipped, and having a stop or projection f adapted
to engage the seat E aforesaid, and serve to steady the body when the vehicle is in
motion, substantially as described.
