IMPROVEMENTS IN APPARATUS FOR STEERING VESSELS
Year: 1885

page_text: I EMIL CARL HEINRICH SAMSCHE of Hamburg, Germany, Engineer do hereby
declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR STEERING
VESSELS, to be as follows:-
The invention relates to improvements in apparatus for steering vessels by
means of an auxiliary propeller screw; and the objects of my improvements are
to facilitate the application of such auxiliary screw and to provide means for
placing it in its proper position.
To effect this, vertical rails are attached to or at the stern of the vessel; they
serve to guide a frame wherein a bow or open frame is pivoted. This bow or
frame bears the screw-shaft. Bevelled wheels or suitable means of communicating
motion communicate the rotation of a vertical shaft to the screw-shaft. A vertical
shaft passes through a hollow shaft, whereon the bow or frame is secured; suitable
gearing allows the hollow shaft to be turned thus placing the bow or frame with
the screw-shaft in the proper direction for steering the vessel.
If the auxiliary screw is not required for steering or propelling the vessel, the
frane may be raised by means of chains, rods or other suitable mechanism.

I EMIL CARL HEINRICH SAMSCHE of Hamburg, Germany, Engineer do hereby
declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR STEERING
VESSELS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The invention relates to improvements in apparatus for steering vessels by means
of an auxiliary propeller screw; and the objects of my improvements are to facilitate

page_text: the application of such auxiliary screw and to provide means for placing it in its
proper position.
To effect this, vertical rails are attached to or at the stern of the vessel; they
serve to guide a frame wherein a bow or open frame is pivoted. This bow or
frame bears the screw-shaft. Bevelled wheels or suitable means of communicating
motion communicate the rotation of a vertical shaft to the screw shaft. A. vertical
shaft passes through a hollow shaft, whereon the bow or frame is secured; suitable
gearing allows the hollow shaft to be turned thus placing the bow or frame with
the screw-shaft in the proper direction for steering the vessel.
If the auxiliary screw is not required for steering or propelling the vessel, the
frame may be raised by means of chains, rods or other suitable mechanism.
In order to make my invention more clearly understood I will describe it with
reference to the accompanying drawing, in which figure 1 is a side elevation of the
auxiliary propelling screw, showing the mechanism for driving and steering the
same; fig. 2 is a back view thereof, fig. 3 is a side elevation of the stern of a vessel
illustrating the application of the auxiliary screw, fig. 4 shows the application of a
modification.
In figs. 1, 2 and 3. a is the vertical shaft for driving the auxiliary screw; it is
rotated by a suitable motor by means of a gear a¹ and communicates its motion to
the horizontal screw shaft d by the bevel wheels e and f. The bow c, whereby the
screw shaft d is supported, is pivoted in the sliding frame b and connected with
the hollow shaft h surrounding the vertical driving shaft a. The hollow shaft / is
turned by means of bevel wheels and i and the hand wheel z in order to bring
the bow c in that direction, which is required for placing the auxiliary screw
towards the suitable direction. The rails g serve to guide the frame b while being
raised or lowered by means of the chains l.
In the modification shown in fig. 4 the sliding frame is dispensed with and the
bow c is pivoted directly in a channel x of the stern post; thus the screw shaft can
not be raised or lowered, but may remain in its position below the water line.
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
The application of an auxiliary propelling screw, the shaft of which is supported
by a pivoted bow, which may be turned by suitable mechanism towards the
direction required for the purpose of steering vessels, substantially as set forth.
Dated this 27th day of November 1885.
