Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Man-
chester, both in the County of Lancaster, and 323, High Holborn, in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object an arrangement of rose box, which in case of
choking can be at once withdrawn to the deck, cleaned out and again put in
place.
I place the rose box as a valve or a valve seat at the bottom of a long vertical
tube forming the uptake and ending with a cap on deck, through which the spindle
carrying the rose box passes. This spindle is jointed at intervals and has guides
and rollers for keeping it centrally in the tube.
On the top of the rose box in some instances I place the valve sliding on the
central rod. In other cases I withdraw the water from the side of the tube,
through a mud box having a valve at top and bottom for the purpose of cleaning
out the mud. Any ordinary pipe is attached to a side tube from this mud box.
I prefer to place a filtering plate between the mud box and the pump.
central spindle itself can be a hollow tube for lightness.

top of the spindle a second short spindle passing through a clamp and ending with
a hand wheel or lever whereby the second spindle can be screwed down tight on to
the first spindle, and hold the latter down in order to prevent further undue force
being exerted. The lower spindle is itself screwed, a nut and check nut or its
equivalent screwed thereon, when the rose box is in place.

A communication by ADOLF MONTIN, of Helsingfors, in the Grand Duchy of
Finland, Inventor.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention has for its object an arrangement of rose box which, in case of
choking, can be at once withdrawn to the deck, cleaned out and again put in
place

page_text: It is best described by aid of the accompanying drawing, in which—
Figure 1 is a sectional elevation and
Figure 2 a plan of one form of the apparatus.
In these A is the rose box, B guard box arranged with suitable_entrance for
water, C yoke firmly fixed to the rose box and forming part thereof; D rod passing
through rose box and to which the latter is firmly fixed by nuts E E and cotter F
passing through yoke and rod; G tubular rod fixed to rod D. This rod extends to
or close to the deck and is jointed at intervals as at H H. I is a yoke fixed to said
tube and useful for hoisting it up by; I covering on deck; K wrought iron tube
extending from the casting or guard box B to the deck the rod G is guided 1
centrally in this tube by suitable projections or guides where requisite in deep
hulls. L branch to pump. M. is a valve seating on which a turned flange of the
rose box rests; N is a valve sliding on the rod G and closing exit to rose box.
The mode of action is as follows:-
The pump sucks from the rose box, thereby raising valve N and sucking out the
"water. Should the rose get jammed in at the bottom, it can be lifted by screwing
out the lid 1' and hauling up rose by a chain passed round pin L'. The guard
outside the rose has a large aperture at the bottom allowing free flow of water and
offering no crevices for dirt to collect. In some cases the water is withdrawn as
shown in Fig. 3. from the side of the tube K through a mud box O having
openings o at top and bottom for the purpose of cleaning out the mud. Any
ordinary pipe is attached to a side tube L from this mud box. It is preferred to
place a filtering plate 1 between the mud box and the pump. To prevent the
suction from bringing the rose box up bodily, a second short spindle Q is placed
above the top of the spindle G passing through a clamp R and ending with a hand
wheel or lever S whereby the second spindle can be screwed down tight on to the
first spindle and hold the latter down. In order to prevent further undue force
being exerted, the lower spindle is itself screwed at g, and a nut and check nut g¹ or
their equivalent screwed thereon when the rose box is in place.
This nut and check nut are screwed up until they are solid in against the
abutment a when the box is in place; all extra strain then from the second spindle
is taken up by the nut and check nut.
The invention in two ways improves upon the usual type of ships' pumps, as it
increases the efficiency through making it possible to have a foot valve on such
pumps and further insures the pump being always in good working order, the rose
being accessible for cleaning out in a moment at any time even when the hold is full
of cargo.
It thus adds considerably to the safety of the ship in critical moments.
The invention is equally well adaptable for sea connections in steam ships, thus
obviating the necessity of docking the ship for examination aud cleaning of roses
and valves; the rod and pipe being of course brought up above the free board mark,
the rose and valve are accessible at any time when the ship is in the water.
the rose is removed, the pipe can be further cleaned through forcing water or steam
into it.
When
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign corespondent, I declare that what I claim is :-
1. The combination of a rose box, a stem or equivalent raising gear attached
thereto and capable of being hauled up with the rose box on to the deck, and an
exterior tube rising above the load line surrounding the same and acting as a guide
for the latter, substar lly as described.
2. The apparatus substantially as and for the purpose described and illustrated
in the accompanying drawings.
