HARRY FREDERICK HL 11 Allan Terrace Sherwood Street Nottingham, Brass-
founder, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction of apparatus for indicating the
proximity of rocks or other danger, & to insure the safety of the vessel should
they not be avoided. In carrying out this invention 1 equip one or more boats with
water proof decks, & the interior with propelling power & electric or other moter.
These boats are driven ahead of the ship by an electric wire or other power trans-
miter, which is payed out from the ship. A second electric cable connects the boats
together, & also to the ship. This cable is also connected with a disc in each boat, which
falls rpon receiving a shock, completing an electric current & ringing a bell on board
ship.
The seccond portion of this invention consists in fitting up the vessel with a number
of bags of india rubber, or other suitable material, which are connected by pipes to a
reservoir of compressed gas of suitable compound. When desirable the gas may be
turned on to fill the bags, thus increasing the buoyancy of the vessel.

COMPLETE SPECIFICATION.
Improvements in and connected with Vessels for Navigation.
HARRY FREDERICK HILL 11 Allan Terrace Sherwood Street Nottingham 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 has for its object the construction of apparatus for indicating the
proximity of rocks or other dangers and to ensure the safety of the vessel, should they
not be avoided. In carrying out this invention 1 equip one or more boats with
water-proof decks & the interior with propelling power which may be electric or other
moter. These boats are driven ahead of the ship by an electric wire or other power
transmitter, which is payed out from the ship. A second cable connects the boats
together & also to the ship. This cable is also connected with a dise in each boat
which falls upon receiving a shock, thus compliting an electric current & ringing a
bell on board the ship. The second portion of this invention consists in fitting up the
vessel with a number of bags of india rubber or other suitable material which are
connected by pipes to a reservoir of compressed gas of suitable compound, when
desirable the gas may be turned on to fill the bags, thus increasing the buoyancy of
the vessel; & in order that the said invention may be better understood. & the manner
in which it is to be performed, I proceed more fully to describe the same.
In the case where an object below the surface is to be indicated two or more pilot-
boats are driven from the vessel, the said pilot-boats having a false keel or its
equivalent which may be lowered to the desired depib, the ends of an electric or other
cable or pipe are attached to the said keels. Upon the boats being set in motion
they diverge from one another the length of the cable attached to the keels (the
divergence being obtained by the setting of the rudders) travelling forward and
sweeping the water at the desired depth. A return current is sent from the pilot
boat or boats by means of a return wire which is connected with the alarm on the
large or main vessel, and which is brought into operation by the falling disc, or by
the severing of the cables or pipes. The said return cable is also connected with an
гр.

page_text: electric magnet on board the large or main vessel, the said magnet being connected
with a spring which is made in turn to act upon the helm and also the cocks for
shutting off steam. The magnet, being charged with the return current, the spring is
liberated acting in turn upon the helm as previously determined.
The pilot boats may also carry lights and also a fog-horn which may be blown by
compressed air or steam generated automatically by electricity, gas, or oil, thus
obviating the necessity of a person on board the pilot-boat.
The reservoirs for inflating the bags may be charged by having a more or less
quantity of water or other liquid within. Above the water in the said air-tight
reservoir is supported a vessel containing suitable chemicals. This said vessel is
attached to a bar passing through the reservoir, which may be operated on from the
outside. The said bar upon being turned round empties the chemicals into the liquid
or other substance producing the necessary gas to inflate the before mentioned
bags. A spring safety valve may be fitted to the reservoir to prevent too great a
pressure.
The details of this invention being easily understood and the whole put in practice.
by any practical person the necessary electrical apparatus being already in use for
railway signalling I do not deem the use of drawings necessary for the application of
this invention.
Having therefore described the said invention and the manner in which the same is
to be applied what I claim is
1. A pilot boat driven in front of the vessel by means of compressed air or other
transmittable power as and for the purpose hereinbefore described.
2. The use of pilot boats connected together as hereinbefore described.
3. The use of coal gas or gas lighter the atmosphere for driving the engines of the
pilot-boats.
5. The sinking of the cables below the surface as and for the purpose hereinbefore
described.
6. The return current from the pilot boat operating the alarm on the main
vessel.
7. The connection of the alarm signal with the pilot boat.
8. The connection of the rudder and steam cocks of the main vessel with the pilot
boats and cables as herein before described.
9. A pilot boat with lights and fog-horns driven ahead of the vessel as hereinbefore
described.
10. The automatic blowing of the fog-horn and driving of the pilot-boat, without
the aid of a person on board.
11. A life préserving apparatus inflated by means of chemicals as in or similar to
the method herein before described.
12. A life preserving apparatus consisting of two or more chambers or parts one of
which is inflexible and non-expansible, the other being flexible and capable of expan-
sion, which parts or chambers may be connected by pipes or airways regulated by
closing valves or springs.
