PROVISIONAL SPECIFICATION.
Improvements in Combined Machinery for Dredging or Excavating
Material, and for Transporting the Dredged or Excavated
Material.
I JOIN PRICE of Greenbank, Grappenhall in the County of Chester Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to structures employed in excavating either under water or
on land say for canals, dockworks, deepening rivers and in the making of railways,
and has for its main object to economically and quickly move the excavated or
dredged material into wagons or the like placed alongside or contiguous to the
water or roadway carrying the apparatus.
For this purpose
make use of any ordinary bucket dredger or excavator and
an endless travelling band or chain running on rollers on a horizontal or nearly
horizontal girder and on a movable jib pivoted to one end of the horizontal girder.
The said girder is supported at each end when used on water upon a floating barge
and pivots or rollers are provided to allow for unequal motion of the barges; when
used on land, rails or trams may be used.
Raising and lowering gear is provided by which the end of the movable jib can
be adjusted to any desired height. The said raising and lowering gear preferably
consists of several ropes or chains provided with spring connections and attached
at one end to the jib at various points in its length.
The other ends of the ropes are led over sheaves at the upper part of a mast
affixed to the horizontal girder and thence to the barge where they are secured.
The mast is stiffened by ropes or struts attached to the further end of the
horizontal girder. The excavated material is delivered by the dredging or
excavating machine on to the travelling chain preferably with troughs affixed at
any point between the barges supporting the girder or between the carriers on
land and is then carried away along the movable jib and discharged into wagons
or otherwise disposed of as desired. When delivering into wagons I prefer to use
a triangular frame on which the material is received resting on the edges of
adjacent wagons to avoid unnecessary spilling of the said material or in place of
the triangular frame provide a travelling hopper receiver which overspans the
wagons one after another.

JOHN PRICE of Greenbank Grappenhall in the County of Chester, 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:-
My invention relates to structures employed in excavation either under water or

When delivering into wagons I prefer to use a triangular frame on which the

travelling hopper or receiver which overspans the wagons one after another.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan, Fig. 2 a side elevation, Fig. 3 an end elevation, and Fig. 4. a
detail view of machinery or apparatus under my invention.
a represents a floating bucket dredger of any usual or suitable type. is the
ladder or chain of buckets. c is a horizontal or nearly horizontal trussed girder
carried at each end on floating barges d. e is a movable trussed jib pivoted to the
girder c. are two series of rollers one along the upper surface and the other
along the lower surface of the girder and jib. hare hexagonal or other suitably
formed carrying and driving pulleys. endless band or chain carried by the
rollers and pulleys 9 h. motor for actuating the driving pulley g, k mast

girders c. mare ropes attached to the mast passing round sheaves n and down to
the barge d. o ropes or chains connecting the sheaves n to the jib e.

carrier i, y are wagons into which the material is delivered, are triangular frames
resting on the edges of adjacent wagons to prevent material from falling between
the wagons.

When in use the jib is raised so that the free end is in the required position.
The dredged or excavated material is delivered to and passes down the shoot p on
to the travelling band or carrier which conveys it and delivers it into the
wagon q.
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 :-
First. Combined machinery for dredging or excavating and transporting
material, substantially as set forth.
Second. In combined dredging or excavating and transporting machinery for
material, using a telescopic shoot between the dredger and transporter.
Third. In combined dredging or excavating and transporting machinery using a
girder and a jib and endless band or chain combined substantially in the manner
and for the purpose set forth.

frames or hoppers and wagons disposed substantially as and for the purpose set
forth.
