Improvements in Dumping Trucks for Conveying Materials in
Fireclay and other Works.
I JOHN GILCHRIST STEIN of Annislea Bonnybridge, in the County of Stirling,
North Britain, Fireclay Manufacturer, do hereby declare the nature of this
invention to be as follows, that is to say :-
My said invention has for its object to improve the construction of dumping
trucks, and more particularly to render such trucks capable of delivering their loads
of clay or other materials on to the working benches in fireclay manufacturing and
similar works, so as to render unnecessary the providing of special elevating
apparatus for the purpose.
In carrying out my invention I have a truck made with a frame which is provided
with three or four wheels and with steering mechanism of an ordinary kind; and on
the frame I fix two standards provided with bearings at the top for the trunnions
or journals of a board or plate forming a platform on which the clay or other
material is placed. The trunnions are near one end of the platform, and it is the
other end of the platform which is tilted up for delivering or dumping the load, the
descending end consequently moving down to only a small extent. The parts are
proportioned to suit the height of the working benches. When the platform is
horizontal its longer end rests on a support fixed to the truck frame; and a lever is
attached to the platform for tilting it, such lever being preferably arranged to be
drawn out to give leverage in the tilting operation, and to be pushed inwards out
of the way at other times.
Dated this Fifteenth day of August 1893.

Improvements in Dumping Trucks for Conveying Materials in
Fireclay and other Works.
1, JOHN GILCHIRST STEIN, of Annislea, Bonnybridge, in the County of
Stirling, North Britain, Fireclay Manufacturer, 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, that is to say:―
My said invention has for its object to improve the construction of dumping
trucks, and more particularly to render such trucks capable of delivering their loads
of clay or other materials on to the working benches in fireclay manufacturing and
similar works so as to render unnecessary the providing of special elevating
apparatus for the purpose..
In carrying out my invention I have a truck made with a frame which is pro-
vided with three or four wheels and with steering mechanism of an ordinary kind;
and on the frame 1 fix two standards provided with bearings at the top for the
trunnions or journals of a board or plate forming a platform on which the clay or
other material is placed. The platform is supported at its longer end and a lever is
attached to it for tilting it to deliver or dump the load.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings, to be

page_text: hereinafter referred to, and showing a dumping truck, for conveying materials in
fireclay and other works, as made with my improvements.
Figures, 1, and, 2, of the drawings are elevations, as at right angles to each other,
of the improved truck. In these drawings the saine reference letters and numerals
are used to mark the same or like parts wherever they are repeated.
As shown in the drawings I have a truck made with a frame, A, which is provided.
with three wheels, B, and, C, and with steering mechanism. The steering mechanism
consists of a handle-bar, D, which extends from the end of the truck, at which the
worker is, to the other end where it is fixed to a toothed wheel, E, (or it might be a
toothed quadrant) turning on a centre stud or pin, F, fixed in a plate, G, on the
truck frame, A. The toothed wheel, E, gears with a pinion, H, fast on the upper
end of a fork, J, which is jointed at its lower end to the axle, L, of the wheel, C, the
upper or spindle part of the fork turning in a bearing, M, on the frame, A. By
moving the handle bar, D, the wheel, C, can be turned quickly so as to steer the
truck. On the frame, A, I fix two standards, N, provided with bearings, P, at the
top, for the trunions or bearing pins, Q, of a board or plate, R, forming a platform
on which the clay or other material is placed. The trunnions, Q, are nearer one end
of the platform, R, than the other, which is tilted up for delivering or dumping the
load, the descending end consequently moving down to only a small extent. The
parts are proportioned to suit the height of the working benches. The platform, R,
is horizontal and its longer end has a block, R1, fixed on it which rests on a
support, R 2, fixed to the truck frame, A, and stayed by bars, S. The platform, R,
and block, R 1, are secured to the support, R 2, by a bolt and pin, R 3, which can
be removed for tilting the platform. A lever, T, is attached to the platform, R, for
tilting it, such lever being arranged to be drawn out through the guides, U, retaining
it to give leverage in the tilting operation, and to be pushed inwards out of the way
at other times. Diagonal stays, V, are employed to strengthen the standards, N.
A brake arrangement, W, is employed in connection with the two wheels, B, such
brake arrangement being actuated by a lever, X, through a rod, X 1, a lever, X 2,
and links, 3. The object of the brake arrangement, W, is to prevent recoil of the
truck during the dumping or delivering operation. A dust and clay guard, Y, is
provided to cover the toothed wheel, E, and pinion, F, and it is fixed to the truck
frame, A, and centre pin or stud, F.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
A dumping truck for conveying materials in fireclay and other works, comprising
a frame running on wheels and provided with steering mechanism, and having on it
a board or plate elevated on standards above the truck frame and capable of
being tilted by a lever, the parts of the said truck being combined and arranged
substantially as and for the purposes hereinbefore described.
