PROVISIONAL SPECIFICATION.
An Improved Combined Rudder and Skeg for Launches or like
Craft.
I, THOMAS GEORGE TAGG of The Island Boat Building Works, East Molesey,
in the County of Surrey, Launch Builder, do hereby declare the nature of this.
invention to be as follows:-
My invention relates to an improved combined rudder and skeg for launches or
like craft.
In carrying it into effect, I provide a vertical slot in and through the skeg and
mount a roller therein loosely upon a horizontal axis. The periphery of the roller
projects below the skeg for a sufficient distance to bar the possibility of the skeg's
rubbing over or upon anything in its path.
The invention is not restricted in respect of the details of the construction of
the roller-these may be varied. I prefer that the roller be a disc of wood tired
with iron and that its axis be a round stud on each side of the slot entering a
circular hole in the middle of the disc, such hole being formed in metal discs fixed
on each side of the roller.
The rudder is pivotted between the counter and the end of the skeg in any con-
venient way, and is so arranged that it will allow an angle of 45 degrees to be
given to the rudder when actuated in the usual manner.
The rudder consists of post, slot in same to take metal plate, tennants and
plates.

SPECIFICATION.
An Improved Combined Rudder and Skeg for Launches and like
Craft.
I, THOMAS GEORGE TAGG, of The Island Boat Building Works, East Molesey,
in the County of Surrey, Launch Builder, 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:—
My invention relates to an improved combined rudder and skeg for launches and
similar craft, and the object of it is to bar the possibility of the skeg rubbing over
or upou anything in its path.
It consists in the combination with the skeg, of an upright roller supported in
a slot in the skeg, by a transverse axis extending from one side of the slot to the
other and about which the roller can turu freely whenever it encounters any
obstacle. The roller is of sufficient diameter to project below the skeg for a
distance that will put the bottom edge of its periphery at least on a level with the
lowest part of the skeg. The constructional details of the roller and.its axle may
be varied.

page_text: Referring to the accompanying drawings:
Figure 1 is a side elevation of the stern of a launch shewing the counter, stern
post, screw, rudder, skeg and roller.
Figure 2 is a side elevation, partly in section of one of the skeg cheeks.
Figure 3 is a sectional elevation taken along the line 3-3 of Figure 1 looking
forward.
'
Figure 4 is a sectional elevation taken along the line 4-4 of Figure 1, likewise
looking forward,
Figure 5 is a side elevation of a roller detached.
a is the counter; b; the stern post; c, the screw and d, the rudder.
The roller illustrated in the figures, consists of a disc of wood e having a metal
tyre and fortified by a cheek e on either side, the two cheeks being held to the
disc and to each other by bolts es. The central hole through which the bolt es
passes, is fitted with a bush . e is a bolt and nut adapted to prevent the
cheeks el, el spreading apart.
The bearing for the roller consists of two extensions e, one on each internal face
of a skeg cheek, both concentric with the axis of the roller and entering central
holes of the same diameter in the cheeks.
elo is the slot in the skeg in which the roller is mounted and turns.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
'The herein before described combination of a skeg and roller.
