Improvements in Driving Mechanism for the Paddle Wheels of Steam
and other Boats.
I, MARTIN HONNICKE, of Vegesack, near Bremen, Engineer, 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 an apparatus for driving the paddle wheels of steam
boats and motor boats and by means of which the paddle wheels that are situated
at the rear part of the boat are driven, and which although it is situated in the
open, will always work properly because the delicate parts of the apparatus are
encased.
The invention is illustrated in the accompanying drawings in which Figure 1
shows the rear part of the boat with paddle wheels and driving apparatus. Figure 2
is a side elevation partly in section.
At the rear part of the boat there is arranged a frame, upon which are fixed.
the bearings for the shaft of the paddle wheels. Between the cross-piece a¹ and
the boat there are provided two stays or struts b, c, which are situated in the
middle between the paddle wheels. The whole driving apparatus of the shaft of
the paddle wheels is fixed upon these two struts b, c. On the middle of the shaft
there is keyed a worm wheel d, into which there engages from below a worm c
that is fixed on a shaft f, which is actuated by the rotation of the motor. The
worm e transmits its motion to the worm wheel d, which in turn transmits its
motion to the shaft of the paddle wheels. Since the driving apparatus is situated
in the open, the bearings, which are arranged on each side of the worm wheel d,
are so constructed that the worm wheel d is at the same time provided with a
casing, which prevents the entrance of moisture. On the casing i there are also
fixed the bearings for the worm e, whereby the entire casing is arranged to form a
closed box. By this means also the worm wheel and the worm can be readily
adjusted in erecting the machinery. The closed casing is also very suitable for
the reason that the worm e can work in an oil bath whereby, as is well known, the
friction is considerably reduced. By means of this easily-running driving
apparatus, considerable saving of motive power is effected, and the said apparatus
can be applied to any paddle wheel boats.
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:-
-
(1). An apparatus for driving the paddle wheel shaft which apparatus is mounted
at the rear end of steam boats' and motor boats with paddle wheels, upon stays
or struts be of a frame a, and which apparatus consists of a worm wheel d that
is fixed upon the paddle wheel shaft, and in which there engages a worm e, mounted
on the motor shaft f, and which worm is mounted with the worm wheel d in
one cosing a

tially as herein before described and shown.
