COMPLETE SPECIFICATION.
Combined Propellers and Steering Apparatus for Boats, Vessels, and
the like.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Buckingham
Street, Strand, W.C., Patent Agent, do hereby declare the nature of this inven-
tion a communication to ime from abroad by Isador Lehman, of the City of Cleve-
land, County of Cuyahoga and State of Ohio, U.S.A., and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
Tuis invention relates to combined propellers and steering apparatus for boats,
vessels, and the like, and inore especially to such class of inventions wherein the
propeller rotates within a non-rotatable cylinder or casing.
This invention consists in securing the non-rotatable cylinder or casing, at the
stern of the boat, in such a manner that the same may be moved or oscillated in
a horizontal direction, and, at the same time, allowing of the free rotation of the
propeller therein, by connecting said propeller to the shaft of the boat by means
of a universal joint-connection.
This invention, also consists in other peculiarities of construction which will
be hereinafter fully set forth and claimed.
In the drawings, Fig. I is a view, in elevation, of a side of a boat showing
the combined propeller and steering apparatus attached.
Fig. II is a sectional view illustrating more clearly, the details of construction
of the universal and slip-joint connection between the propeller-shaft and the
main shaft of the engine.
Fig. II is a plan view illustrating one manner in which the propeller and
steering apparatus may be oscillated or turned horizontally, or kept in predeter-
mined position, as desired.
.
A, represents a boat of any suitable construction to the rear or stern of which
is secured a propeller casing B of suitable diameter to receive a pro-
peller C and allow the same to freely revolve therein. The casing B
is, preferably, provided with a band B which acts to reinforce the casing B and
afford a support for the same. At the upper portion of the band B' a shaft
is provided which is secured to said band in any suitable manner and extends up-
ward through the stern of the boat supporting the casing B and pivoting the same
in position.
Ay
To the upper end of the shaft is secured any suitable means, such as a
pinion D, for operating the casing B with its propeller C for the purpose of turn-
ing the same in either direction, and thus directing or steering the boat.
illustrated in Fig. III, when the pinion D is employed at the upper end of the
shaft a suitable segmental rack E is also used, which meshes with said pinion.
The rack E is suitably pivoted or secured to the boat so as to be freely oscilated,
thus rotating the pinion D, shaft b, casing Band propeller C. However, as
herein before set forth the apparatus for oscillating or moving the cylinder B and
its contained propeller C may be modified and any suitable means employed, such
as are well known to the craft.
In order to allow of the free horizontal oscillation of the propeller C and, at
the same time revolve the same in the desired direction by means of connecting it

page_text: to the main shaft of the engine F, a universal joint is provided which is preferably
constructed as illustrated more clearly in Fig. II of the drawings.
G represents the shaft upon which the propeller C is mounted, as illustrated
in Fig. II, and by means of which it is directly rotated in either direction. To
the inner end of the shaft D is secured a universal joint connection II which
allows of the bending or knuckling of said shaft in any and all directions relative
to the axis of the same, but, inasmuch as the oscillation of the casing B and its
contained propeller C about its pivotal point b would alter the length of said shaft
according to the position it occupied, a slip-coupling J may be provided which is
so secured to both or either shafts For H that, while it prevents the slipping
of said shaft around the axis of the same and' communicates rotary motion from
one to the other, it will allow of the lengthening of said connection between the
main shaft and the propeller shaft G, thus rotating the propeller C in predeter-
mined directions regardless of the position it may occupy.
The universal joint-connection H and the slip-coupling J may, however, be
constructed in any well-known operative manner or form well-known, providing
they allow of the free oscillation in a horizontal direction, of the casing B and
its propeller Cand; at the same time, rotate said propeller within said casing.
Figs. I and II illustrate a peculiar construction of propeller, but this invention
is not limited to this construction, inasmuch as it may be modified without depart-
ing from this invention, it only being essential that the propeller should be en-
closed within a casing such as B, so as to freely rotate therein, and that said
casing B and propeller rotating therein be secured to the stern of the boat in such
a manner that the casing B with its propeller C will oscillate horizontally to
control the direction of the boat, and while being oscillated will freely rotate to
propel the boat.
Other, modifications may be made in the invention without departing from the
gist of the same.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A combined propelling and steering apparatus comprising a casing which
is nonrotatable around its horizontal axis but free to move in a horizontal direction,
and means for moving it in said horizontal direction and a rotating propeller
mounted within said casing; said-propeller being provided with a universal joint
connection whereby the propeller and casing may be moved in a horizontal
direction, substantially as set forth.
2. A combined propeller and steering apparatus, comprising a revoluble pro-
peller mounted and enclosed within a non-revoluble casing and means whereby
both propeller and casing may be directed or moved in a horizontal direction.
3. A combined propeller and steering apparatus comprising a revoluble pro-
peller connected by means of a universal joint to the propelling shaft of a boat,
and journaled within a non-revoluble casing, and means secured to said casing
for moving or directing both propeller and casing horizontally, substantially as
set forth.
4. The combination in a propelling and steering device of the type set forth:
of a rotating propeller; a casing within which said propeller is mounted and
rotated; universal joint-connection between the driving shaft of said propeller
and the propeller, and means for horizontally directing or turning both casing
and propeller, substantially as set forth.
