Improvements in Dredging Machinery.
I, FRED LOBNITZ, Director of Lobnitz & Coy. Ltd, residing at Clarence House,
Renfrew, County of Renfrew, Scotland, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement.
This invention relates to diedging machinery and it has for its object to pio-
vide dredgers with improved means whereby the materials diedged can be dis-
charged at a distance from the dredge itself
Under this invention the discharging means takes the form of a long shoot
or couloir which is so supported in position and so connected to the dredger
that it can be swung round into different positions so as to discharge the spoil
either to one side or other of the dredger oi astein
This long shoot discharging device is very useful when diedging or cutting
canals and other water-ways as the spoil can be readily discharged on to either
bank as desned
And in order that my said invention may be properly understood I have
hereunto appended two explanatory sheets of drawings, whereon,
Fig. 11s a side elevation of a dredger provided with a "universal" long shoot
or coulon discharging device
Fig. 2 18 a plan of a similar diedgei
Refening to the drawings whereon the same reference letters wherever repeated
indicate the same parts
In the diedge m, Figs 1 and 2, the long shoot a, which preferably takes the
form of a tube of, say, 200 feet in length, is supported in position by means of
vertical stays b secured at their upper ends to sheer legs' e, cl, and by horizontal
stays secuted to booms d, d, and to the framing The sheer legs are
cariied upon a small barge or pontoon f The sheer legs c, c', are held in
position by powerful struts g, h, which, at then meeting points, are jointed to
the framing e The joint may, as shown at Fig 1, take the form of a strong
pivot pin working in sockets made in the framing at Each pan of
struts g, h, may be tied together by tie bais 7
J,
The struts g, h, which are jointed to the ends of the sheer legs so as to permit
of a relative movement between the baige f and the dredger m, serve to connect
the barge to the dredger
11s a funnel connected to the front end of the shoot a and into which the
spoil from the buckets is discharged
m² indicates an awning on the diedger and baige.
The shoot a may be provided with rails as shown
The stavs b, b, may be made of wue 1ope or other suitable material
With this arrangement, whenever necessary, the shoot a can be slewed round,
by manoeuving the barge f, either to the port side of the dredger, as indicated
in full lines at A Fig 2, or to the starboard side, as indicated in dotted lines
at A¹ Fig. 2, so as to discharge the spoil at either the one side or the other of the
vessel

page_text: It is to be understood that the constructive details of the arrangement may be
altered or modified without departing from the invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
consider novel and desire to claim is
-
A dredger having combined with it a long discharging shoot or couloir so
arranged that it can be moved round so as to discharge the spoil at one side or
other or astern of the vessel as desired, substantially as herein before described
with reference to Figs. 1 and 2 of the drawings annexed.
