thereby, in effect substantially providing a stern
This invention relates to sailing vessels, par
ticularly toy or model sailboats and especially to
helm-controlling means therefor.
It is an object of the present invention to pro
5 , vide a wind-actuated device‘ which will serve to
alter the course of a sailing vessel whereby it is
headed in the direction of the wind.
It is another object of the present invention
to provide means for maintaining a sailing ves
: sel in the Wind, that is to say, to maintain it with
its keel pointing in the direction of the wind.
It is a. further object of the present invention
post for the ship separate from the hull.
A rudder shaft 20 positioned within openings
formed in the members l3 and I6 and abutting at
the end thereof against the member I 8 carries CH
a rudder 2|, the said shaft being freely rotat
ably movable within the limits determined by
the abutment of a portion of the rudder against
the member l6 substantially as shown in Fig. 5.
The upper portion of the rudder shaft is bent to 10
form a loop substantially as generally indicated
at 22, which is in alignment vertically with the
to provide a structure of a the type indicated
rudder, the shaft being bent upwardly after the
wherein the wind-actuated means can be altered
: to provide for predetermined variations in the
course of the vessel as it is acted upon by winds
loop has been formed therein to form a continua
tion of the rudder shaft substantially as illus
trated in Fig. 3. A wind-actuated member 23 is
blowing from different directions.
'
It is a feature of the device according to the
present invention that it is simple in construc
‘; tion, comprises comparatively few parts that are
not readily liable to fall into disrepair.
The invention will be fully and comprehensive
ly understood from a consideration of the fol
lowing detailed description when read in connec
tion with the accompanying drawing which forms
‘part of the application.
‘
In the drawing:
Fig. 1 is substantially a perspective view show
ing a device according to the present invention
mounted in working position on a vessel;
Fig. 2 is a top plan view of the preferred em_
bodiment of the present invention;
7
Fig. 3 is a side elevation of the structure illus
trated in Fig. 2;
’
Fig. 4 is a side view partially in section of a
portion of the device illustrated in Fig. 3; and
Fig. 5 is a horizontal sectional view of Fig. 3
taken along the line 5-5.
Referring now to the illustrated embodiment of
1 the present invention, wherein a sailing vessel I0
is provided with helm-controlling mechanism,
generally designated at II, it will be noted that
the helm-controlling mechanism is mounted on
the stern i2 of the vessel by means including a
bracket l3 substantially as shown in Figs. 1 and
3. The bracket [3 is provided with two openings
near an end thereof in one of which is mounted
the dependent standard I 4 attached to said mem
ber I3 by means including a pair of lock nuts
IS. The lower portion of the standard carries
a guide member it mounted thereon preferably
by means of lock nuts Ill and a lower plate I 8
attached to the standard preferably by lock nuts
L9. The standard and the various members at
55 tached thereto are substantially non-rotatable
associated with the upward portion of the rud
der shaft by means including a shaft 24 whereon
the wind-actuated member is mounted, said shaft
having a loop formed on the free end thereof 20
adapted to be received upon and held between
spring-pressed washers 25 mounted on the upper
portion 26 of the rudder shaft, substantially as
shown, said washers being held in. position by
lock nuts 21 and 28, these details being best
illustrated in Fig. 4.
.
If desired, the member 23 can be rotated about
the shaft 24 by loosening the lock nuts 29 or 3D.
Avresilient elastic or spring member 3|, attached
to the loop 22, formed in ‘the rudder shaft is
?xedly held at the opposite end thereof at a
place on the vessel in line with the keel thereof
whereby the rudderis normally moved into align
ment with the keel.
.
In use, if it is desired that the vessel be caused
to head into the direction of the wind, the wind
actuated member 23 is disposed in substantial
alignment with the rudder 2| upon the shafts 20
and 26, whereby assuming, for example, in Fig.
1 that the wind is coming from the left of the
vessel (when the vessel is regarded from the
front) it will be noted that the wind-actuated
member 23 will be moved toward the right of the
vessel, thereby causing the vessel to turn and
head in the direction of the wind.
45
It will be noted that when the keel is in align
ment with the direction of the wind, the resilient
member 3| attached to the loop 22 in the rudder
shaft will tend to cause the rudder to move into
alignment with the keel, thereby maintaining 50
the vessel in its course, substantially as herein
before described. It will of course be apparent
that if it is ‘desired to cause the vessel to travel,
for instance, in a circular course, that the mem
ber 24 can be turned about the shaft 26, thereby 55
2
2,112,171
causing the member 23 to be positioned out of
alignment with the rudder 2| on the rudder shaft.
By this means, as long as a Wind is blowing in the
direction of the boat the rudder will be moved
slightly out of alignment with the keel, thereby
causing the vessel to alter its course to a corre
sponding degree.
It will be noted that the device according to
the present invention provides means for arrang
10 ing the direction of the course of a model sail
boat to follow a predetermined design as well as
to maintain a vessel of the type indicated on a
course before the wind irrespective of changes in
the direction of the wind.
It will also be noted that the member 3| at
15
least largely minimizes alteration of the course of
the vessel due to movement of the vane 23
through rolling effects.
It is to be understood that this improvement
20 is capable of extended application and is not con
?ned to the exact showing of‘the drawing nor to
the precise construction described and, therefore,
such changes and modi?cations may be made
therein as do not affect the spirit of the invention
nor exceed the scope thereof as expressed in the
appended claims.
