PROVISIONAL SPECIFICATION.
Improvements in Propelling Ships or Vessels.
JAMES PASCOE Mining Engineer 10 Harbour Terrace Falmouth, do hereby
declare the nature of my invention for IMPROVEMENTS IN PROPELLING SHIPS
OR VESSELS to be as follows:-
The application of a series of hollow, watertight floats to the paddle wheel or
wheels of ships or vessels. Such wheel or wheels to be driven by mechanical or
other means. The hollow watertight floats take the place of the flat or curved
paddles or floats at present fitted to paddle wheels. They may be of any convenient
shape or form. Paddle wheels fitted with these improved floats are preferably
placed as near as convenient on either side of the keel of the ship or vessel and
may be in any position in the length of the said ship or vessel.
Paddle wheels fitted with these improved floats may work in an air and watertight
casing or casings formed in the ship or vessel and covering the top part of the
paddle wheel, the bottom being open to the sea; thus keeping any water from
coming into the said ship or vessel. The driving shaft may work through a stuffing
box in the side of the said casing or casings.
The improved float may be fitted to "feather" in the same manner as ordinary
paddle wheel floats are sometimes arranged. The improved float may be fitted in
the place of existing paddles.
I do not confine myself to placing paddle wheels fitted with these improved floats
as above stated, they may be placed outside the ship or vesssel and on either side
as commonly done or one or more may be placed at the stern or at the bows or
both.
Nor do I confine myself to a hollow float, they may be made of such material as
shall be buoyant of itself.
The hollow watertight floats are buoyant and give increased efficiency.
Dated this 25th day of August 1893.

COMPLETE SPECIFICATION.
Improvements in Propelling Ships or Vessels.
JAMES PASCOE Mining Engineer Harbour Terrace Falmouth, 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 application of a series of hollow, watertight and buoyant floats to the paddle
wheel or wheels of ships or vessels. Such wheel or wheels to be driven by
mechanical or other means. The hollow, watertight and buoyant floats take the
place of the flat or curved paddles or floats at present fitted to paddle wheels.
They may be of any convenient shape or form, of any suitable material and are
preferably made as light as possible. Paddle wheels fitted with these improved
floats are preferably placed as near as convenient on either side of the keel of the
ship or vessel, and they may be in any position in the length of the said ship or
vessel.

page_text: Paddle wheels fitted with these improved floats may work in an air and watertight
casing or casings formed in the ship or vessel and covering the top part of the
paddle wheel, the bottom being open to the sea, thus keeping any water from
coming into the said ship or vessel.
"
The driving shaft may work through a stuffing box or boxes in the side of the
said casing or casings. The improved floats may be fitted to "feather in the
same manner as ordinary paddle wheel floats are sometimes arranged. The improved
floats may be fitted in the place of existing paddles.
I do not confine myself to placing paddle wheels fitted with these improved floats
as above stated, they may be placed outside the ship or vessel and on either side as
commonly done or one or more may be placed at the stern or at the bows or both,
enclosed in a casing or casings or otherwise. Nor do I confine myself to hollow
floats, they may be made of such material as shall be buoyant of itself.
The accompanying drawing shews one way in which the improved floats may be
applied.
Fig. 1. is an elevation of a wheel fitted with hollow, watertight and buoyant
floats.
Fig. II. is an end elevation of same.
Fig. III. is an elevation of part of a ship with two wheels fitted with the improved
floats.
Fig. IIII. is a cross section through the ship.
The same reference letters apply to all the figures.
V is the ship.
W. W. the paddle wheels.
F. F. F. the hollow watertight and buoyant floats.
S. S. the shaft on which the wheels W. W. are mounted, running in suitable
bearings.
M. M. are the cranks to which the motive power is applied, such power being
applied to each wheel seperately or conjointly.
C. C. are the casings in which the wheels work.
B. B. are stuffing boxes on the sides of the casings C. C. and through which the
shaft S. S. works.
W. Z. is the supposed water line of the 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―
I. The application of hollow watertight and buoyant floats to the paddle wheel
or wheels of ships or vessels.
II. The combination of buoyant floats fitted to a paddle wheel or wheels and
protected by a casing or casings as set forth in the accompanying drawing and
description.
