PROVISIONAL SPECIFICATION.
Marine Signalling for Preventing Collisions at Sea.
ROBERT FOSTER, Saw Miller, 8, Woodside Place, Shettleston, Glasgow, do hereby
declare the nature of this invention to be as follows:-
That in addition to the red and green regulation lights carried by ships, an
additional red and green light are carried with round globe lamps, a shade passing
round each globe. The lamps to have a foot or so of a stem a small pulley on the
end of each stem, with a belt passing to the axle of the wheel, or any other part of
the steering gear, to operate, so that when the wheel is turned to port the ships helm,
she exhibits the red light over her bows and shades the green light, at same time
she exhibits the green light over her stern and shades the red, showing to vessels
approaching on bow, or stern, the position of her helm, or a change to starboard

COMPLETE SPECIFICATION.
Marine Signalling for Preventing Collisions at Sea.
J, ROBERT FOSTER, 8 Woodside Place, Shettleston, North Britain, Saw Miller, 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 which relates to marine signalling for preventing collisions at sea,
consists in so connecting the signalling apparatus with the steering gear whether
operated by hand, steam, electricity, or in any other way, that whenever the wheel
is operated upon either to tarn the ship to starboard or to port the signalling apparatus
is simultaneously operated upon, thus showing the direction in which the ship is about
to turn.
In carrying out my invention I provide the ordinary red and green regulation
lights carried by ships, with an additional red and green light, each of which additional
lights has a shade or cover passing round it, and these shades or covers are connected
to a spindle inside the tower which again are connected to a belt, chain, or cord which
passes to the axle of the wheel or to any other convenient part of the steering gear,
so that when the wheel is turned to port the ship, the second green light is also
fully exhibited over the ship's bows, and the red light is shaded, and vice versa.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one explanatory sheet of drawings.
Figure 1 is a plan of the hull of a slip.
Figure 2 is a section of the lamp tower;
Figure 3 is an elevation; and Figure 4 is a horizontal section of Figure 2.
A is the additional light, and B is the spindle in the tower C to which is connected
the shades or covers D. EE are the cords or belts which are connected from the
spindle B in the tower C to the axle of the wheel F, so that when the wheel is turned
either in the one direction or the other the additional light is also fully exhibited,
thus indicating in which way the ship is about to turn.
It is to be understood that although I have only shown one way of connecting
the belts or chains with the steering gear, other ways may be adopted.

page_text: 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 :-
Marine signalling for preventing collisions at sea by having a connection between
the lamps and the steering gear, so that when the wheel is turned either in one
direction or the other an indication of the direction in which the ship is about to
turn is thereby indicated.
