1, JOSIAH MCGREGOR of 78 Queen Victoria Street in the city of London Engineer,
do hereby declare the nature of this invention to be as follows:-
.
This invention relates to the arrangement and method of applying the power to
stern wheel Steamers whereby the cylinders may be placed conveniently in the ship or
vessel (near the boilers) and thereby avoid the inconvenience and loss occasioned by
the ordinary arrangement of boilers and engines being placed far apart.
The ship or vessel is so constructed at the stern as to be capable of accomodating the
stern wheels and afford attachment for a rudder abaft of the wheels, thereby securing
improved efficiency thereof.
The means by which I am enabled to place the machinery as above is by using long
rods or preferably an extension of the piston rod, working either horizontally or
inclined, and transmitting the motion either directly to connecting rods or through the
medium of swinging or rocking levers.
The above method may be applied in several ways.
First By leading these rods along or near the centre of the ship or vessel
conveniently protected under the decking or floors, or by a casing, and connected
as above to the cranks between the wheels, which are placed at right or other angles
to one another. They are connected together in this position by means of a link
attached to a projection on the inner side of each crank pin.
Secondly By leading the rods along the side of the ship or vessel conveniently
protected and connected as above to the cranks placed on the outer side of the wheels.
The cranks are placed at right or other angles-and the crank shaft is either in one
length or coupled by a coupling in the centre or by other cranks as in the first
instance.
Thirdly By an application of the second arrangement to the usual single stern
wheel steamer, in which instance the rudders may be before the wheel or otherwise.
Fourthly By a combination of the first and second means slightly modified, by
which the rods are led along at the sides and middle. There may be either one or two
rods in the middle and the cranks may be at any suitable angle.

Improvements in Stern Wheel Steamers.
I JOSIAH MCGREGOR of 78 Queen Victoria Street in the City of London Engineer
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 relates to the arrangement and method of applying the power to
stern wheel steamers whereby the cylinders may be placed conveniently in the ship
or vessel (near the boilers) and thereby avoid the inconvenience and loss occasioned
by the ordinary arrangement of boilers and engines being placed far apart.
The ship or vessel is so constructed at the stern as to be capable of accommodating
the stern wheels and afford attachment for a rudder abaft of the wheels, thereby
securing improved efficiency thereof.
The means by which I am enabled to place the machinery as above stated is by
using long rods or preferably an extension of the piston rod working either horizontally
or inclined and transmitting the motion either directly to connecting rods or through
the medium of swinging or rocking levers.
The above method may be applied in several ways as for instance -
First By leading the said rods along or near the centre of the ship or vessel
conveniently protected under the decking, floors, or by a casing and connected as
above to the cranks between the wheels which are placed at right or other angles to
one another. They are connected together in this position by means of a link
attached to a projection on the inner side of each crank pin.
Secondly By leading the rods along the sides of the ship or vessel conveniently
protected and connected as above to the cranks placed on the outer side of the wheels.
The cranks are placed at right or other suitable angles and the crank shaft is either in
one length or coupled by a coupling in the centre or by other cranks as in the first
instance.
Thirdly By an application of the second arrangement to the usual single stern
wheel steamer in which instance the rudders may be before the wheel or otherwise.
Fourthly: By a combination of the first and second means, slightly modified, by
which the rods are led along at the sides and middle. There may be either one or two
rods in the middle and the cranks may be at any suitable angles.
In order that my Invention may be fully understood I will describe it more
particularly by the aid of the accompanying drawings in which are represented three
different arrangements for communicating the power of the engine or engines to the
stern wheels.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation partly sectional of a portion of a vessel constructed in
accordance with this Invention. Fig. 2 is a half plan or horizontal view and half
horizontal section of the same showing one arrangement for communicating the power
to the stern wheels. Figures 3 and 4 are sectional and stern views of the same.

page_text: Fig. 5 is a similar elevation and Fig. 6 a plan of a second arrangement and
Figures 7 and 8 are sectional and stern views of the same. Figures 9. 10. 11 and 12
are corresponding views representing a third arrangement for the same purpose.-In
these several figures the same letters of reference indicate corresponding parts.
A is a projection of the vessel beyond where the lines proper at the stern terminate,
and is a central prolongation aft, which serves not only for supporting the inner wheel
bearings and framework but also the rudder abaft of the wheel, securing the greatly
improved action thereof. The projection A may be made as shewn or be merely a
strong open framework connected to the ship or vessel proper.
The rudder may be an ordinary rudder as indicated, or it may be a balanced rudder,
or multiple rudders placed at different positions forward and aft or athwartships in the
projecting framework A.
The advantage of an easy run to the ship or vessel is also secured by this
arrangement as illustrated by the stern views Figures 4. 8 and 12.
In each of the three modifications illustrated by the drawings the engines are shown
as arranged in convenient proximity to the boilers while in two of them (Figures 1. 2.
5 and 6) the power of the engines is shown to be transmitted to the cranks directly by
means of long rods 1 working through guides B, and in the third modification
through swinging or rocking levers between those rods and the ordinary connecting
rods of the cranks. In Figures 2 and 10 the rods D are shewn as led from the
engine to the cranks in the centre of the ship or vessel (as to its width) and in
Fig.
the rods D are shewn as led along the side of the ship or vessel and connected
to the cranks placed on the outer side of the wheels; but in each of these arrange-
ments the engines and boilers are in convenient proximity to each other instead of
being far apart.
From the above illustrations it will be obvious that the arrangements of these
special means of conveying the power of the engines to the cranks may be varied so
long as the engines and boilers are arranged near together in any convenient part of
the ship or vessel.
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 :-
The arrangements and methods described of applying the power to stern wheel
steaners in order that the cylinders and boilers may be placed near together in any
convenient part or parts of the ship or vessel substantially as and for the purpose or
purposes described.
