COMPLETE SPECIFICATION.
a
Improved Apparatus for Removing Accumulations of Mud, iSilt, or
Sand in Rivers and Tide-ways, particularly applicable for
Salvage Vessel.
I JOHN MORCOMBE BROMLEY BAKER, of 48 Stockwell Park Crescent, in
the County of London, Dredging Contractor, 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 designed to facilitate the removal of mud, silt and sand in
rivers and tide-ways, and is particularly applicable for a salvage vessel, as by its
means deposits may be cleared away from under a stranded vessel, which can be
consequently re-floated, and if desired towed away by the salvage vessel.
And in order that ny said invention may be clearly understood, I will now
proceed to describe the same with reference to the drawings accompanying this
Specification in which
Fig. 1 shows a side elevation of a vessel, fitted with my improved apparatus,
Fig. 2 half deck plan of same,
Figs. 3 and 4 are details hereafter referred to.
The same letters of reference denote the same parts in all the views.
a shews the vessel, b gimballs, on which the tubes c¹ and c are mounted, shews
guards, for protecting the tubes c and c', shewn in end view at Fig. 4 (enlarged).
The tubes c and e¹ are provided with jets d, e shews toothed quadrant, connected
to the tube c', by means of casting o. The quadrant e works in worm f, which is
supported by an arm p, attached to the gimball b. This arrangement is shewn
clearly at Fig. 3 drawn to an enlarged scale.
The drawing at Fig. 1 shews the position that the tubes c¹ and c would assume,
when out of action, i.e. a horizontal position, and parallel with the sides of the
vessel a.
When it is desired to use my improved apparatus, the wheel is turned, by which
the worm is rotated. This causes the quadrant e to turn, which will bring the
tubes c¹ and c more or less towards the vertical position as shewn by dotted lines in
s Fig. 2 shews
Fig. 1 the tubes c and c¹ being connected together by the rods h.
recesses to allow of the action of the tubes c cathwartship.
In order to adjust the tubes c¹ and c to the desired angle athwartship I provide
another quadrant & fitted at right angles to the quadrant e, and shewn also detached
at Fig. 3. This is also fitted to the gimball band is actuated by another worm m,
which is turned by a handle n.
The hose pipes q are connected at one end to the pipes c¹ and c and at the other
end to suitable pumps (not shewn on the drawings), by means of which powerful
jets of water will be directed on to the deposits, in order that the latter may be
dispersed by the tide.
Although I have shewn three tubes on each side of the vessel a 1 do not want to
confine myself to this, as I may have any other number, nor do I wish to confine
myself to the precise method described for operating the said tubes in order to
place them in position athwartship and fore and aft. h are rods for connecting the
tubes c c¹.
I may if desired have the apparatus fitted to only one side of the vessel, but I
prefer to have it on both sides as shewn.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is :-
:-
1. In apparatus for removing accumulations of mud silt or sand in rivers and
tide-ways, the employment of tubes fitted to a vessel, so that they may be turned
into position fore, aft and athwartship, substantially as set forth.
2. In apparatus for removing accumulations of mud silt or sand in rivers and
tide-ways, the employment of tubes, fitted to the side or sides of a vessel, such
tubes being connected together, in such a way that upon turning one tube into
position, the other tubes on the same side shall be similarly turned, for the purposes
set forth.
3. The improved apparatus for removing accumulations of mud silt or sand, in
rivers and tide-ways constructed and operated substantially as set forth.
