IMPROVEMENTS IN THE CONSTRUCTION OF PADDLE WHEELS FOR STEAM SHIPS
Year: 1884

page_text: I, THOMAS PHILLIPS of Aberdare in the County of Glamorgan, do hereby declare
the nature of said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF
PADDLE WHEELS FOR STEAM SHIPS," to be as follows:-
Under this Invention the paddles or blades are arranged on the two sides of a
central circular disc which, with the blades, may be cast in two or more sections,
the sections being bolted or otherwise secured together around the paddle shaft.
The paddles or blades are tapered, increasing in breadth from towards the centre
of the wheel outwards. At the side nearest the ship and at the side furthest
therefrom are placed circular rims bearing against the outer ends of the blades.
The inner rim is of larger diameter than the central disc aforesaid which is of
larger diameter than the outer rim, so that floating obstructions may be readily
thrust aside outwards from the wheel.
A cover or guard of sheet metal is secured to the outer rim aforesaid and serves
to prevent floating objects from entering in at that side of the wheel.

page_text: I, THOMAS PHILLIPS, of 2, Waynes Street, Aberdare, in the County of
Glamorgan, Underground Fireman, do hereby declare the nature of my Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF PADDLE WHEELS FOR STEAM
SHIPS," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof and the
Drawings therein referred to :-
Under my said Invention the paddles or blades are arranged on the two faces of
a central circular disc or plate which with the paddles or blades may be cast in two
or more sections, the sections being bolted or otherwise secured together around
the paddle-wheel shaft.
The paddles or blades are tapered, increasing in breadth as they extend
outwards from the wheel centre. At the side nearest the ship and at the side
furthest therefrom are situated circular rims or rings bearing against the outer
ends of the paddles or blades.
The inner rim is of larger diameter than the central disc which is of larger
diameter than the outer rim, so that floating obstacles may be readily thrust aside
outwards from the wheel. A cover or guard of sheet metal or other suitable
material is secured to the outer. rim aforesaid and serves to prevent floating objects
entering the wheel at that side.
And in order that my said Invention may be properly understood, I now
proceed to describe the same with reference to the accompanying Sheet of Drawings
and the Figures and letters marked thereon.
Fig. 1, on the accompanying Sheet of Drawings represents a side view, as seen
from the outside, of a paddle wheel constructed, in accordance with one method
comprised in my said Invention.
One half of the cover or guard A is removed. Also one half of the outer rim e.
Fig. 2. represents a sectional plan of the wheel.
The paddles or blades a are cast with the central circular disc b, on each side of
which they are arranged.
In the wheel represented, the disc b is formed in two sections which are bolted
together around the paddle shaft c. The disc b may be made up of more than two
sections if required. The paddles a may either be made of the shape shown in the
Drawing, that is to say increasing in breadth as they extend outwards, or they
may be otherwise shaped as desired.
Instead of being arranged abreast on each side of the disc b, the paddles on one
side may be placed at any desired points between those on the other. They may
be made independently of the disc b and be designed to oscillate on pivot pins
conveniently fitted for that purpose between the disc b and the side rims d and e,
the range of oscillation being governed by stops fixed before and behind each
paddle. The paddles would thus act as "feathering" floats. At the side of the
wheel nearest the ship is the circular rim or flat ring d secured to the outer ends
of the paddles on that side. A similar rim e is fitted to the outer ends of the
paddles on the side futhest from the ship. The rim d is of larger diameter than
the central disc b which is of larger diameter than the rim e. Floating obstacles
may thus be more readily thrust aside outwards from the wheel than would be the
case if the disc and rims were of the same diameter.
The cover or guard A of sheet metal or other suitable material is secured to the
outer rim e and serves to prevent floating objects from entering the wheel at that
sida

page_text: 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 :-
Constructing paddle wheels for ships in such manner that the paddles or blades
are arranged around a disc or plate placed intermediately between rims or flat
rings by which the paddles are bordered at each side, the rim nearest the ship
being of larger diameter than the intermediate disc which is of larger diameter
than the outside rim, substantially as herein before described, the paddles being
either of the fixed or "feathering" type.
