PROVISIONAL SPECIFICATION.
An Improved Apparatus to use on Ships' Davits for Obtaining
Rapid and Safe Launching and Lowering of Boats under All or
Any Conditions.
OLIVER PHALP Almorah Richmond Road Cardiff Marine Superintendent do hereby
declare the nature of this invention to be as follows:-
The apparatus consists of fitting worm wheels of suitable size keyed on one or
both davits of each boat and this worm wheel is acted on by a spiral wheel working
into such worm wheel attached to a fast bracket in such position and manner as may
be found convenient. So that when it is necessary to swing out a boat by this
apparatus it is only necessary for one person to work a handle secured to a spiral
wheel spindle to swing out the davits to any required position without using guys
or other usual means the davits remaining in any desired position.
My second plan for same purpose is to use a suitable sized bevelled wheel, keyed
on davits and a corresponding bevelled wheel of much smaller diameter, secured to
a bracket in like manner as the first plan. Excepting by this plan the davits lock
themselves when swung out to the proper position for lowering, also without use of
guys being required. The two methods being substantially one plan except a
worm & spiral is used in first, and bevelled wheels in second.
Dated this 6th day of April 1889.

An Improved Apparatus to use on Ships' Davits for Obtaining
Rapid and Safe Launching and Lowering of Boats under All or
Any Conditions.
OLIVER PHALP, 37 Richmond Road Cardiff Marine Superintendent, 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:
The apparatus consists of a worm wheel of suitable size keyed on one or both
davits of each boat, and this worm wheel is acted on by a spiral wheel working into
such worm wheel, the spiral wheel being attached to a fast bracket in such position
and manner as may be found convenient, so that when it is necessary to swing out a
boat by this apparatus, it is only necessary for one person to work a handle secured
to the spiral wheel spindle to swing out the davits to any required position, without
using guys or other usual means, the davits remaining in any desired position locked
by spiral wheel.
My second plan for same purpose is to use a suitable sized bevelled wheel keyed
on to davits and a corresponding bevelled wheel of much smaller diameter, secured
to a bracket in like manner as first plan, the two methods being substantially one
plan except that a worm and spiral is used in first plan, and two bevelled wheels in
the second.
Either plan, but more particularly the first, is applicable to the swinging out of
anchor davits and anchor cranes as shown in the drawings.
The said invention will be readily understood by reference to the accompanying
drawings.
Figure I. represents a view of the apparatus fitted complete to a davit.
Figure II. represents the spiral wheel and bracket with spindle and handle

as in Figure I, showing arrangement for revolving davits or anchor cranes on board
ship.

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
1
First the introduction of such apparatus combined of several parts for the purpose
of being used to revolve the davits of boats and thereby reducing the difficulties in
getting ship's and steamer's boats safely into the water.."
Second the application of such above described apparatus to anchor: davits and
anchor cranes for which purpose the apparatus, is highly suitable.
In-witness whereof I; the said Oliver Phalp, have hereinto set my, hand and seal.
Dated this 2nd day of January 1890.
