We, ALEXANDER Joss, ROBERT TOWNS, and ALEXANDER KYNOCH all of the
firm of Joss, Towns and Kynoch, Engineers of the Caledonian Engine Works,
Wellington Road in the City and County of Aberdeen, and WILLIAM REID of
Lossiemouth in the County of Elgin, North Britain, Fish Curer, do hereby declare
the nature of the said invention for A NEW OR IMPROVED PADDLE WHEEL AND
MEANS OF APPLYING PADDLE WHEELS TO VESSELS to be as follows:-
This Invention, which relates to a new or improved Paddle wheel, and means of
applying Paddle wheels to Vessels, the same being especially adapted for Fishing
boats, consists in constructing such Paddle wheels and their directly connected
driving shafts that they may be readily shipped or unshipped.
In constructing a Paddle wheel according to this Invention, the floats are secured
to angle or T iron arms or spokes the inner ends of which are secured by bolts or
their equivalent into a central boss. The floats are maintained in their respective
radial positions by means of a ring composed of segments each of which segments
is secured at its two ends, by bolts or their equivalent, between lugs formed on the
floats. This construction of Paddle wheel admits of the saine being taken apart
and stowed away into a comparatively small space.
"
"
The central bosses of the Paddle Wheels constructed according to this Invention
are secured upon the driving shafts by means of nuts forcing the same on to conical
portions of such shafts, the said bosses being bored out with corresponding cones.
The driving shafts used in connection with these Paddle wheels are formed in two
parts, the inner extremities of which are squared or provided with feathers or
their equivalent to admit of their sliding inwards towards each other while
remaining geared with the sleeve into which they are fitted.-This sleeve is
provided with toothed or equivalent gear wheels by means of which the two
portions are rotated from the engine which is preferably of the compound vertical
type. The arrangement of driving shaft herein before described admits of the outer
extremities of the same, after the removal of the Paddle wheels therefrom, being
drawn inwards thereby leaving the sides of the vessel clear and unimpeded for
sailing purposes.

A New or Improved Paddle Wheel and Means of Applying
Paddle Wheels to Vessels.
We, ALEXANDER JOSS, ROBERT TOWNS, and ALEXANDER KYNOCH, all of the
firm of Joss, Towns and Kynoch, Engineers of the Caledonian Engine- Works,
Wellington Road, in the City and County of Aberdeen, and WILLIAM REID of
Lossiemouth, in the County of Elgin, North Britain, Fish Curer do hereby declare
the nature of our invention for A NEW OR IMPROVED PADDLE WHEEL AND MEANS
OF APPLYING PADDLE WHEELS TO VESSELS, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Our Invention, which relates to a new or improved paddle wheel, and means of
applying paddle wheels to vessels, the same being especially adapted for fishing
Boats consists in constructing such paddle wheels and their directly connected
driving shafts that they may be readily shipped or unshipped.
In constructing a paddle wheel according to this Invention, the floats are 'secured
to angle or iron arms or spokes the inner ends of which are secured by bolts or
their equivalent into a central boss. The floats are maintained in their respective
radial positions by means of a ring composed of segments each of which segments
is secured at its two ends by bolts or their equivalent, between lugs formed on the
floats This construction of paddle wheel admits of the same being taken apart
and stowed away into a comparatively small space.
The central bosses of the paddle wheels, constructed according to this Invention'
are secured upon the driving shafts by means of nuts forcing the same on to
conical portions of each shafts, the said bosses being bored out with corresponding
cones. The driving shafts used in connection with these Paddle wheels are formed
in two parts, the inner extremities of which are squared or provided with
"feathers" or their equivalent to admit of their sliding inwards towards each other
while remaining geared with the sleeve into which they are fitted.-This sleeve is
provided with toothed or equivalent gear wheels by means of which the two
portions are rotated from the engine, which is preferably of the compound vertical
type. The arrangement of driving shaft herein before described admits of the outer
extremities of the same after the removal of the paddle wheels therefrom, being
drawn inwards thereby leaving the sides of the vessel clear and unimpeded for
sailing purposes.
In order that our Invention may be. properly understood and readily carried-into
effect, we will now proceed to describe the drawings hereunto annexed.
Figure 1; is a side elevation of a paddle wheel as constructed according to our
present Invention.
Figure 2, is a plan of a mid-ship portion of a vessel fitted with apparatus con-
structed according to and constituting our present Invention.
Figure 3, is a transverse section of the same.

page_text: In constructing a paddle wheel according to our present Invention, the floats a,
are secured by rivets or otherwise to the onter ends of the angle or T-iron arms or
spokes b. The inner ends of the spokes b, fit into recesses formed in the central
boss c, and are secured therein by means of bolts or rivets as represented at d,
Figure 1, or their equivalent. The floats a, are maintained in their respective
radial positions by means of the ring e, which is composed of segments each of
which segments is secured at its two ends by the bolts for their equivalent, which
pass therethrough, and through the lugs g, formed on each of the sides of the said
floats a, as shewn more particularly at Figure 3 of the annexed drawings.
"
The central bosses c, of the paddle wheels are bored out conically as shewn at
Figure 3 and the outer ends of the two parts h, and i, of the driving shaft are
turned with corresponding cones as represented at j, and k, respectively. At the
outside of these conical portions j, and k, of the divided driving shaft there are
formed screws which admit of the nuts 1, being threaded thereon as hereinafter
more particularly explained. The inner or adjacent ends of the two parts h, and i,
of the driving shaft enter the sleeve m, in which they are prevented from rotating
independently of the said sleeve by means of "feathers or their equivalent but
which "feathers" readily admit of their sliding inwards towards each other. The
sleeve m, is provided with the toothed gear wheels n, and o, or their equivalent
which, by means of the intermediate gear wheels p and q, admit of their being
thrown into gear with the engine A, which engine we prefer to be of the compound
vertical type. The relative arrangement of the gear wheels n, o, and p, q, admits
of the paddle wheels being rotated at a greater or less speed according as either of
the wheels n, or o, is geared with the engine through its own particular inter-
mediate gear-wheel. These intermediate gear wheels may be slid longitudinally
along the shaft r, by means of a lever or other suitable device so that the paddle
wheels may be geared with the engine in the manner herein before described or they
may be disengaged from the engine in the manner indicated at Figure 2 of the
annexed drawings, in order that the paddles may freely revolve should the vessel
be under way. The sleeve m, is supported in the bearings 8, in which it is
prevented from moving longitudinally and the two parts h, and i, of the driving
shaft, are supported in the journals or bearings t, the brasses of which are free to
slide longitudinally inwards with the shafts h, and i, when they are being shipped
and thus at the same time preserve practically water-tight joints.
When it is desired to secure the paddle wheels to the ends of the driving
shafts h, and i, the said shafts are moved outwards from the sleeve m, in opposite
directions until their ends project out from the sides of the vessel. Upon these
projecting ends, the central bosses c, of the paddle wheels are passed and by the
nuts, the conical holes of the said bosses are secured tightly upon the conical
portions j, and k, (Figure 3) of the shafts. When the paddle wheels in the reverse
manner are detached from the ends of the shafts h, and i, the said shafts may be
drawn inwards and the sides of the vessel thereby left clear and unimpeded for
sailing purposes, and the paddle wheels by being dismembered or reduced to
individual parts may be stowed away into a comparatively small space.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what
we claim is
First. A paddle wheel constructed with floats secured to the angle or T-iron
arms b, the inner ends of which fit into recesses formed in the central bosses c, and
the floats of which are held apart in their respective radial positions by means of
the segmental portions of the ring e, all of the parts of the paddle wheels being
so connected to one another as to readily admit of being dismembered or taken
apart for the purpose of enabling the said paddle wheels to be stowed away into a
comparatively small space all substantially as herein before set forth with reference
to the annexed drawings.

page_text: Second. The arrangement and construction of the driving shafts of fishing boats
or other vessels in two parts the two inner ends of which are so connected through
a sleeve m, that the said parts h, and i, after the removal of the paddle wheels
therefrom, may be drawn inwards and thereby leave the sides of the vessel clear
and unimpeded for sailing purposes all substantially as and operating in the manner 5
herein before set forth with reference to the annexed drawings.
