PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Transporting and Dumping Earth
or other Materials Removed by Dredgers or the like..
We, JAMES SAMUEL HOBROUGH, and JAMES HOBROUGH, both of Bishop
Bridge, Norwich, in the County of Norfolk, Contractors, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to improved apparatus for conveying earth or other
materials from one place to another, for instance, from a dredger to the shore or
bank of a river, canal or the like, and automatically dumping or discharging the
same..
In carrying out our invention we provide a tram-road mounted on a suitable
support and adapted to receive a see-saw motion so as to cause a waggon placed upon
the said tram-road to run from end to end of the same according to the direction
in which the said tram-road is tilted or inclined.
In using our apparatus in conjunction with a dredger we advantageously_mount
the tram-road on a trestle or other support carried by an independent lighter or
float which is so placed that one end of the tram-road is over the dredger, whilst
the other end extends to the point at which the material is to be dumped.
tram-road is preferably mounted upon the trestle in such a manner that it is
capable not only of a see-saw motion thereon but also of a rotary or transverse
movement.
**
The
On each side of the supporting trestle we fix other trestles which serve to limit
the see-saw movement of the tram-road one of such trestles being, say, on the
dredger and the other on the bank.
In order to alter the inclination of the tram-road we advantageously adopt the
following arrangement :-
At the end of the tram-road over the dredger we fix an automatic dog adapted
to hold the chain of the crane working the grab dredger the said chain, when the
waggon has been filled, being brought against the dog so that the latter will hold
the same, the chain is then raised to tilt the platform sufficiently to cause the
loaded waggon to run towards the shore end of the tram-road, the waggon when it
has passed over the centre of the tram-road striking a lever connected to the dog
by a chain or the like so as to release the crane chain leaving the crane free to
continue the dredging. When the waggon reaches the shore end, an attendant
dumps the contents whereupon a counterweight on the dredger end of the tram-
road again tilts the latter so that the waggon runs towards the dredger to receive
another load.

or other Materials Removed by Dredgers or the like.
We, JAMES SAMUEL HOBROUGH and JAMES HOBROUGH, both of Bishop
Bridge, Norwich, in the County of Norfolk, 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 improved apparatus for conveying earth or other
materials from one place to another, for instance, from a dredger to the shore or
bank of a river, canal or the like, and dumping or discharging the same.
In carrying out our invention we provide a tram-road mounted on a suitable
support and adapted to receive a see-saw motion so as to cause a waggon placed
upon the said tram-road to run from end to end of the same according to the
direction in which the said tram-road is tilted or inclined.
In using our apparatus in conjunction with a dredger we advantageously mount
the tram-road on a trestle or other support carried by an independent lighter or
float which is so placed that one end of the tram-road is over the dredger, whilst
the other end extends to the point at which the material is to be dumped. The
tram-road is preferably mounted upon the trestle in such a manner that it is
capable not only of a see-saw motion thereon but also of a rotary or transverse
movement.
On each side of the supporting trestle we fix other trestles which serve to limit
the see-saw movement of the tram-road, one of such trestles being, say, on the
dredger and the other on the bank.
In order to alter the inclination of the tram-road any suitable means may be
employed we, however, advantageously adopt the following arrangement :-
the same.
At the end of the tram-road over the dredger we fix an automatic dog adapted
to hold the chain of the crane working the grab dredger, the said chain, when the
waggon has been filled, being brought against the dog so that the latter will hold
The chain is then raised to tilt the platform sufficiently to cause the
loaded waggon to run towards the shore end of the tram-road; the waggon when
it has passed over the centre of the tram-road striking a lever connected to the
dog by a chain or the like so as to release the crane chain leaving the crane free to
continue the dredging. When the waggon reaches the shore end, an attendant
dumps the contents whereupon a counterweight on the dredger end of the tram-
road again tilts the latter so that the waggon runs towards the dredger to receive
another load.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
:-
Figure 1 is an elevation of our improved apparatus :
Figure 2 is a part plan of the same:
Figure 3 is an end elevation of the tram-road:
Figure 4 is a plan of Figure 3; and,
Figure 5 shews a plan of the dog for holding the crane chain.
a is the tram-road fulcrummed on a bar, fixed to the turn-table c. d is the
trestle or support carrying the turn-table c, and e the independent lighter or float
carrying the said trestle or support d. f, g are the trestles or supports limiting the
see-saw movement of the tram-road a, and is the dredger carrying the trestle y
and also a suitable crane (not shewn) provided with a grab for dredging.
is the dog for holding the crane chain j, and a lever for putting the dog in and
out of gear with the said chain, the said lever passing through a slot in the upper
framework m at one end of the tram-road a and through a slot n in the dog i
which slides in the said upper frame m.

page_text: One end of the dog i is provided with a slot o whilst the other end is connectel
to a lever p situated near the other end of the tram-road a by means of the chain q
which passes over the pulleys and s.
t is a recess or opening in the frame m to receive the crane chain j, and u is the
waggon on the tram-road for conveying and dumping the dredged material.
The operation of the apparatus is as follows:-The waggon being charged by
the crane the dog i is caused to slide in the frame m by means of the lever k so
that the crane chain j can be caused to enter the recess t whereupon the dog i is
moved back and engaged with the chain j, as shewn clearly in Figure 3. The
chain is then raised by the crane to tilt the platform or tram-road sufficiently to
cause the loaded waggon to run to the other end of the tram-road.
When passing
the lever p the said waggon strikes the same by means of a projection p', thereby
operating the dog i and releasing the crane chain and leaving the crane free to
continue the dredging. When the waggon reaches the other end of the tram-road
its contents, are dumped and the tram-road again tilts over by means of the
counterweight so that the waggon ruus again towards the dredger end of the said
tram-road.
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 :-
1. In apparatus for transporting and dumping earth or other materials, a tram-
road mounted on a suitable support in such a manner as to receive a see-saw motion
so that a waggon placed upon the said tram-road runs from end to end of the
same according to the direction in which the said tram-road is tilted, substantially
as described.
2. In an apparatus of the kind described in Claim 1, means for tilting the tram-
road consisting of a dog fixed to the end of the tram-road arranged to grip a chain
attached to the crane or other apparatus so that when the said chain is raised the
tram-road is tilted, substantially as, and for the purpose, described.
3. In an apparatus of the kind described in Claim 2 the arrangement by which
the waggon in passing from one end to the other of the tram-road automatically
releases the crane chain from the dog, substantially as, and for the purpose,
described.
4. In an apparatus of the kind described, trestles or supports arranged at each
end of the tram-road for limiting the see-saw movement of the same, as set forth.
5. The improved apparatus for transporting and dumping earth or other
materials herein before described and illustrated in the accompanying drawing.
