Improvements in Feathering Paddle-wheels.
I, ORANGE JULL, residing at 195, Cowan Avenue, in the City of Toronto, in the
County of York and Province of Ontario, Canada, Gentleman, 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 certain new and useful improvements in paddle wheels,
and to so construct the paddle wheel that the buckets or paddles will enter the
water without percussion or jarring and when submerged present their full area
to the water to take advantage of its entire resistance, and to leave the water
without lifting it or raising a swell, is the object of the present invention; and it
consists of a paddle wheel embracing in its construction two side frames consisting
of the usual centres, arms and rings revolvable with the paddle wheel, and a series
of independent paddles or buckets carried by the side frames, arranged to be
set at any predetermined angle to the vertical axis of the paddle wheel, and
revolved about their own axes during the revolution of the paddle wheel, in order
that they will continuously during the revolution of the paddle wheel maintain
their same relative position to its vertical axis; as hereinafter more fully set forth
and more particularly pointed out in the claims.
IN THE DRAWINGS:
Fig. 1 is a perspective view of a paddle wheel showing the paddles or buckets
moved into a position in which their faces are substantially at right angles to the
vertical axis of the wheel.
Fig. 2 is a view of a modification, showing the paddles or buckets moved into
a position in which their side faces are substantially parallel with the vertical axis
of the wheel.
Fig. 3 is a transverse sectional view through the paddle wheel and shaft.
Like letters of reference refer to like parts throughout the specification and
drawings.
A, A, represents the two side rings, B, B, the arms, C, C, the centres, and D the
hub of the paddle wheel. This much of the paddle wheel is similar to the paddle
wheels ordinarily used."
E, E, represent the paddles or buckets each of which consists of a hub e, sub-
stantially equal in length to the distance between the rings A, A, with sufficient
clearance to allow of the free rotation of the hub, and two blades e¹, el, projecting
from opposite sides of the hub e. Each of the hubs e is mounted on a shaft F, the
ends of which are journaled in the rings A, A. The distance between thie
shafts F, F, is slightly greater than the entire width of each of the paddles or
buckets E, E, in order that sufficient space will be provided for the free revolution
of the paddles or buckets. The same end of each of the shafts F is provided with
a crank G, by means of which the shafts and paddles or buckets are rotated.
Each of the cranks G is provided with a crank pin H.
I represents a frame coupling together the crank-pins, and by means of which
the cranks and paddles or buckets are caused to move in unison.
D...

page_text: The relative position of all of the cranks to their respective paddles or buckets
is the same, in order that the paddles or buckets can all be maintained in the same
relative position to the vertical axis of the shaft of the paddle wheel.
As shown in Fig. 1 of the drawings the frame I is provided with an annular
centre J.
K represents the shaft of the paddle wheel to which the hub D is rigidly fixed.
The shaft K is journaled in bearings L. Passing through one of the bearings L
and surrounding the shaft K is a sleeve M, to the inner end of which is fixed
The
an eccentric 0, and to the outer end of which is connected a crank P.
eccentric is substantially of the same diameter as the centre J, and when the
parts are assembled in position the eccentric O is contained within the centre J,
which then acts as an eccentric strap for the frame I. By means of the crank P the
eccentric can be moved into any predetermined relative position to the vertical
axis of the shaft K and carry with it the frame I to alter the relative angle of the
paddles or buckets to the vertical axis of the shaft. The paddle wheel revolves with
the shaft K, and during its revolution carries with it the frame I. The revolution
of the frame I about the eccentric ( turns the paddles or buckets E, E, about
their respective shafts and continuously maintains them at the same relative
In other words, if the paddles or
angle to the vertical axis of the shaft K.
buckets E, E, are set perpendicular the revolution of the paddle wheel will cause the
frame I to continuously turn the paddles or buckets E, E, about their shafts, and
maintain them continuously in a perpendicular position during the revolution of the
paddle wheel, so that the paddles or buckets can enter the water in a perpen-
dicular position and pass through and leave the water in the same position, in
order that the entire resistance of the water may be taken advantage of to propel
the boat, and also to prevent the paddle wheel lifting the water or raising a swell
during its revolution. Instead of using the eccentric and annular centre, as
shown in Fig. 1, of the drawings, it is possible to provide the sleeve M with a
crank Q and connect it to the frame I by means of a pin, for the purpose of
shifting the position of the frame to vary the inclination of the paddles to the
vertical axis of the shaft.
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
1 claim is:
-
1. A paddle wheel embracing in its construction two side frames, a series
of revolvable paddles or buckets journaled in the side frames, a crank for each
paddle or bucket, a moveable frame connected to the cranks, to cause their united
movement, and carried by the paddle wheel during its revolution, substantially
as specified.
2. A paddle wheel embracing in its construction two side frames, a series
of revolvable paddles or buckets journaled in the side frames, a crank for each
paddle or bucket, a moveable frame connected to the cranks, to cause their united
movement, and carried by the paddle wheel during its revolution, and means
for shifting the position of the moveable frame, substantially as specified.
3. A paddle wheel embracing in its construction two side frames, a series
of revolvable paddles or buckets journaled in the side frames, a crank for each
paddle or bucket, a moveable frame connected to the cranks, to cause their united
movement, and carried by the paddle wheel during its revolution, and means
for shifting the position of the moveable frame consisting of a moveable eccentric,
and an annular centre for the frame working on the eccentric, substantially as
specified.
4. A paddle wheel embracing in its construction two side frames, a series
of revolvable paddles or buckets journaled in the side frames, a crank for each
paddle or bucket, a moveable frame uniting the cranks, an annular centre for
the moveable frame, a shaft for the paddle wheel, a sleeve embracing the shaft,

page_text: an eccentric mounted on the sleeve engaging the annular centre of the moveable
frame, and means for varying the position of the eccentric, substantially as specified.
