I WILLIAM ANDREW of Rectory House East Tilbury in the County of Essex
Master Mariner do hereby declare the nature of this Invention to be as follows:-
My Invention has for its object to provide means whereby ships boats are secured
to the ship and released therefrom for lowering with great facility the "angling" of
the boat to clear the davits being obviated.
According to my Invention the davits are arranged outside the length of the boat
so as to accommodate the whole length of the boat between them whereby they do not
obstruct the free outward passage of the boat. Any ordinary or suitable lowering
gear can be used and when the boat is secured to the vessel the upper parts of the
davits are "fore and aft" or in line with the boats keel.
The keel of the boat rests on the top of the ships rail and against an angle iron or
flange secured to the inner side of the rail-Jointed to this angle iron or flange are
bracket pieces or rests for the inboard side of the boat and to the upper ends of these
bracket pieces or rests are secured catch pieces taking over the edge of the boat and
readily removable. The said bracket pieces or rests are supported by struts which
may be secured to the deck of the ship so that they can be removed and the bracket
pieces or rests be turned down when the boat is to be brought inboard. When the
boat is to be lowered the catch pieces of the brackets or rests are removed and the
boat can be brought clear of the ship by one outward movement of the boat without
any "angling" movement being given thereto.

Ships' Boats.
I, WILLIAM ANDREW of Rectory House East Tilbury in the County of Essex,
Master Mariner 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 has for its object to provide means whereby ships boats are secured
to the ship and released therefrom for lowering with great facility the "angling" of
the boat to clear the davits being obviated.
According to my Invention the davits are arranged outside the length of the boat
so as to accommodate the whole length of the boat between them whereby they do not
obstruct the free outward and inward passage of the boat. Any ordinary or suitable
lowering gear can be used and when the boat is secured to the vessel the upper parts
of the davits are "fore and aft" or in line with the boats keel.
The keel of the boat rests on the top of the ships rail and against an angle iron or
flange secured to the inner side of the rail.
Jointed to this angle iron or flange are bracket pieces or rests for the inboard side
of the boat and to the upper ends of these bracket pieces or rests are secured catch
pieces taking over the edge of the boat and readily removable. The said bracket
pieces or rests may be supported by struts which may be secured to the deck of the
ship so that they can he removed and the bracket pieces or rests be turned down when
the boat is to be brought inboard. When the boat is to be lowered the catch pieces of
the brackets or rests are removed and the boat can be brought clear of the ship by one
outward movement of the boat without any "angling" movement being given thereto.
And in order that my Invention may be fully understood I will proceed to describe
with reference to the accompanying drawings the system mode or manner in or under
which the same may be performed but I premise that I do not limit myself to the
precise details illustrated as it will be evident that they may be varied without
departing from the nature of my Invention.
Figure 1 is a transverse section of part of a vessel and Figure 2 is a side view of
the same showing means for stowing or securing and releasing ships boats according
to my Invention, the boat being shewn as being stowed or secured to the Vessel-
A are the davits revolving in collars a and footstep bearings a³ the collars a and the
parts of the davits which revolve in them being provided with stops which allow the
davits to be swung only through a quarter rotation on either side of the position shewn
one quarter rotation being to carry the boat clear of the vessel for lowering and the
reverse quarter rotation being to carry the boat inboard. The said davits A are
arranged outside of the length of the boat so as to accomodate the whole length
of the boat between them as shewn clearly in Figure 2 so that the boat can pass
freely between them. The lowering gear may be of any suitable or ordinary
description. As illustrated it consists of the tackles C. The connection of the boat
with the tackles is by means of the eyes d of the lower blocks of the tackles engaging
the eyes e on the boat so that their tendency is to assist by their angular placement
the moving of the boat out from the vessel or inboard. F is the rail of the vessel

page_text: upon which the keel G of the boat rests. An angle iron f is secured to the rail
for the inward side of the boat's keel to bear against and pinned or jointed to the
lugs of this angle iron fare bracket pieces or rests h h for the inboard side of the
boat to rest against as shewn clearly in Figure 1. These bracket pieces or rests h h
are supported by the struts i which are secured to the deck of the vessel by bolts .
When the boat is to be brought inboard the struts i can be removed and the brackets
be turned down upon the centres by which they are connected to the lugs f*. In
order to further secure the boat keel slip stops are provided to prevent the boat's keel
from slipping off the rail. These are shewn at j in Figures 1 and 2 and in detail in
Figure 3 and 4-The said keel slip stops j slide up and down on pins k in the rail-
Their lower ends are connected to bell crank levers & centered at to pieces m secured
to the rail the pieces j being maintained in their elevated position by pins as at n.
The lower arms of the levers I are secured to a rod p which can be moved lengthwise
so as to bring all the levers / into the position shewn in dotted lines in Figure 3 and
so lower the keel slip stops / clear of the boat's keel.
Q represent lashings furnished at one end with hooks taking over the outboard side
of the boat and secured at the other end to slip hooks q secured to the vessel. Similar
hooks are passed over the inboard side of the boat and secured with the intervention
of a slip hook one to each of the brackets h. When the boat is to be lowered the
hooks are removed from the side thereof by unfastening the slip hooks. The slip hooks
which secure the lashing of the lowering tackle are unfastened the rod p is moved so
as to lower the keel slip stops j and then the bolt (which by the spring of the tackle
will have cleared the rail) is pushed out the davits turning over the water. The
lowering is then effected by the lowering tackle there being no "angling" of the boat
to clear it from the davits such as is needed in the ordinary method of placing ships
boats in the lowering position.
R shews span tackle for drawing the heads of the davits to the line of the boats keel
in returning the boat to the rail preparatory to securing the boat.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
FirstFor stowing or securing and releasing ships boats an arrangement of davits
and securing devices substantially as hereinbefore described whereby "angling" of
the boat in moving out for lowering and in stowing is obviated and the boat is housed
upon the ships rail.
Second-For stowing or securing and releasing ships boats the combination of
davits so arranged that they accomodate the whole length of the boat between them
with the bracket pieces or rests for supporting the inboard side of the boat sub-
stantially as described and illustrated.
Third-For stowing or securing and releasing ships boats bracket pieces or rests
on the inboard side of the ships rail to form a receptacle for the boat substantially as
described whether the angle iron be used with the rail or not.
Fourth-For stowing or securing and releasing ships boats bracket pieces or rests
on the inboard side of the rail substantially as described the said bracket pieces or
rests forming a receptacle for the boat and being arranged to be turned down or out
of the way for bringing the boat inboard substantially as described.
Fifth The arrangement and combination of parts constituting the apparatus for
stowing or securing and releasing ships boats substantially as hereinbefore described
and illustrated by the accompanying drawings.
