PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Propelling Ships or Vessels.
THOMAS ROBERT WAITE 4 Rose Lane Norwich Tin Plate Worker do hereby
declare the nature of this invention to be as follows :-
A spindle is made to fit through a socket which is fixed to a hole in the side of a
vessel below the water mark. The end of the spindle inside the vessel is attached
to the machinery in the engine house, for action. On the end projecting outside
the vessel is fixed a block and on this block a number of blades, which are made
similar to screw propeller blades, but are curved and twisted the reversed way, to
beat the water similar to a paddle wheel. I then make a case to check the action
of half these blades, this case is in the shape of a half circle flat box hollowed and
bulged, to drop over the blades half way down to the spindle. This case can be
fixed stationary to the sides of the vessel, or can be made with a socket to fit the
spindle, so from a movement inside the vessel the case can be dropped under the
propeller to cover the lower blades. When this case is held over the propeller
the vessel moves ahead, and when dropped under the vessel moves astern, without
reversing the action of the propeller.
My invention relates to the following
1st. The construction of the propeller which is made to give a side action to
propel a vessel as described. The propeller can be made of steel or any other
material which is and can be used for such a purpose.
2nd. The case can be made any shape to stop the action of half the blades, and
can be fixed stationary or movable as described.
3rd. The two being fitted to the sides of vessels amidship or anywhere below
the water mark, receiving the driving power through the sides.

Improvements in Apparatus for Propelling Ships or Vessels.
I, THOMAS ROBERT WAITE, late of 4 Rose Lane, Norwich, but now residing
at 15 Out Risbygate, Bury St. Edmunds, in the County of Suffolk, England,
Metal Plate Worker, 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 propulsion of ships or vessels, and consists
essentially in arranging at each side of a ship or vessel one or more suitably
shaped propellers.
In order that the invention may be clearly understood reference is made to the
accompanying sheet of drawings, in which
Figure 1, represents an elevation of a vessel or ship fitted with side propellers.
Figure 2, is a transverse section of same.
Figure 3, is an enlarged view of a propeller in its haif casing.
Figure 4, is a side sectional view.

page_text: Figure 5, is also a side sectional view but shewing a movable half casing.
Figure 6, shews an indicator and handle arranged inside the vessel for adjusting
the position of the movable half casing.
In carrying out my invention arrange the main shaft (A) transversely or
across the ship or vessel at or about amidships, or at any other suitable position
below the water line, and I may employ more than one shaft if required, according
to the speed that it is desired to propel the vessel. Said shaft is rotated in the
usual minuner by suitable machinery. The end portions of said shaft or shafts as
the case may be, project through the sides of the ship and carry suitably shaped
propellers (1) provided with a suitable number of blades (C). These blades are
constructed so that the tip portion (D) of each blade will be in a line with the axis
of the propeller, while the portion formed on or attached to the boss (E) will be at
right angles to said tip; the blades being curved in this manner have an action
similar to a submerged paddle wheel. The curve or twist of the propeller blades
as shewn in the drawings for one side of the ship, would be in the opposite direction
for the other side of the ship. A half casing or box (F) is arranged over each
propeller in order to check the action of the blades as their power is exerted, su
that at each revolution of the propeller, only the blales not in the casing have
power on the water.
Said easing or box (F) may be permanently secured to the ship as shewn in
Figures 3 and or it may be made movable as in Figures 5 and 6, in this latter
case a sleeve (G) is attached to the casing or box (F), and upon the portion inside
the vessel is a lever hundle (H) arranged in front of a dial (1). In Figures 5
and 6 the position of said handle (H) indicates the position of the easing (F) when
the vessel is going ahead" and by placing the lever or other mechanism in the
reverse position, each casing or box is turned under the propeller, and enuses the
vessel to be propelled "astern," it being nunecessary to stop the engines when
altering the position of said casing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :
Firstly. In the propulsion of ships or vessels, one or more suitably shaped
propellers each arranged within a half easing (F) at each side of a ship or vessel
below the water line substantially as herein fully explained.
Secondly. In the propulsion of ships or vessels, the construction of submerged
side propellers in the manner as herein described and as illustrated.
Thirdly. In the propulsion of ships or vessels, the movable half casing (F) over
ench propeller, which can be operated from inside the vessel by a handle or other
suitable mechanism, so as to cause the vessel to be propelled either "ahead," or
astern as desired, without stopping the machinery.
