PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Shipping or Transferring Coal and
other Materials.
I, WILLIAM SHAPTON, of 8 Great George Street, Westminster, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention is applicable in cases where the rails, supporting the trucks
delivering the goods to be shipped or transferred, are at right angles to the
quay wall.
Such rails are made to terminate a short distance from the edge of the quay, the
space between it and the ends of the rails being at a lower level than the ground
behind and on this lower portion there is a travelling crane running on rails
parallel to the quay. This crane carries a cradle to receive the trucks, means for
lifting, running forward and tipping the cradle and truck, a shoot for the material.
emptied from the truck and it may be a box and crane for receiving and lowering
the same.
The cradle when in its lowest position rests on the ground, suitable bearing
blocks being provided to support and keep it in place. It has rails upon it which
when it is in this position form continuations of one or other of the sets of rails on
which the trucks run. Chains are attached to the cradle which pass over pulleys
on a carriage running on rails at the top of the crane and from thence over pulleys
on a hydraulic cylinder and ram. The carriage is worked to and fro on the rails
by a hydraulic cylinder and ram fixed to the crane and to it respectively.
The action of the apparatus is as follows:-The cradle being in its lowest
position a truck is run directly onto it and it with the truck are raised by the
chains. When at their highest position the cradle and truck are run forward
towards the edge of the quay by traversing the carriage from which they are
suspended, they are then tilted in the usual way by means of a chain attached to
the rear end of the cradle and the material is emptied out of the truck down the
shoot.

Improvements in Apparatus for Shipping or Transferring Coal and
other Materials.
I, WILLIAM SHAPTON, of 8 Great George Street, Westminster, in the County
of Middlesex, 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 :—
This invention is applicable in cases where the rails, supporting the trucks
delivering the goods to be shipped or transferred, are at right angles to the
quay wall.
Such rails are made to terminate a short distance from the edge of the quay, the
space between it and the ends of the rails being at a lower level than the ground
behind and across this lower portion there is a travelling crane running on rails
parallel to the quay. This crane carries a cradle to receive the trucks, means for
LD.

page_text: Figure 1 is a side elevation of an apparatus constructed according to this
invention, the upper part of this figure is on Sheet 1 and the lower part on
Sheet 2. Figure 2 is a plan.
a is the quay and 6 the water. cc are a pair of rails running at right angles to
the quay wall there being a number of parallel sets of such rails. d d are a pair
of rails parallel to the quay wall. ee are the wheels supporting the crane and
running.on the rails d. is a cradle carrying rails f1 and these when the cradle is
resting on the blocks f' (as shown in dotted lines at the bottom of Figure 1) form
continuations of the rails c. The cradle fis suspended by four chains G¹ from the
beam (shown in front elevation in Figure 3) which in its turn is suspended by
two chains G which pass successively over the pulleys g g on the carriage J the
pulleys g¹ g¹ on the frame of the apparatus the pulleys 99 on the head of the
hydraulic ram H' the pulleys ³ ³ on the cylinder H the pulleys 91 91 on the frame
and have their ends fixed at 98 9' to the carriage J. The latter is supported on
wheels running on rails ¹ and is fixed to the ram K¹ of the hydraulic cylinder K.
When the cradle and truck are being lifted the carriage is in the position shown in
dotted lines in Figure 1 water is then admitted to the cylinder K and the carriage
is pushed to the position shown in full lines, this does not raise or lower the cradle
and truck because the chain taken up by the motion of the pulleys g is given out
by the motion of the points 9°. The cradle and truck when raised are tipped by
the chain L whose lower end is divided into two branches (see Figure 3) which
pass over the pulleys on the beam ƒ³ and are fixed to the rear end of the
cradle. The chain L passes upwards and then successively over the pulley (
(Figure 2) on the carriage J, the pulley on the frame, the pulley 15 on the head
of the hydraulic ram M', a pulley between the two pulleys 9 on the head of the
ram H, pulleys on the frame and its end is fixed to the carriage J at the
point 78. When the cradle and truck are being lifted which is done by admitting
water to the cylinder H, the chains G and L work together whilst the tipping
is performed by admitting water to the cylinder M which actuates the chain L
only.

The crane is traversed along the rails d by a hydraulic engine N (indicated in
diagram) whose shaft n carries at each end a bevel pinion n'. The pinions n¹
gear with bevel pinions n² on the vertical shafts n' whose lower ends carry worms n*
gearing with worm wheels upon the axles e¹ of the wheels e.
O is a shoot pivotted to a slide o working in guides in the frame and which is
suspended by two chains P the back one of which passes over the pulley p p¹ p*
and p down to the drum pt. The front chain P passes over the pulley p³
down
to vertical and horizontal pulleys not shown in the drawings to the drum p°. The

page_text: drums p and p are turned simultaneously by the hydraulic engine Q. The outer
end of the shoot is operated by the hydraulic engine R by means of a chain S
which passes from the drum r successively over the pulleys & s¹³ ³ ³ 36 37 3ª and
has its end fixed at s'.
The connections for leading the water to the cylinders and engines are of usual
construction and are not shown in the drawings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of the quay wall, rails at right angles to the wall and
terminating a short distance from its edge, a cradle carrying rails which when the
cradle is lowered form a continuation of the first mentioned rails and a crane
movable along the quay wall and carrying means for lifting running forward and
tipping the cradle substantially as described.
2. Apparatus for shipping or transferring coal and other materials substantially
as described and shown in the drawings.
