Improvements in Looking Devices for Tillers of Ships, Boats,
Yachts, and the like.
I MOSTYN FREDERICK LLOYD TRINGHAM of Penygraig, Aberporth, Cardigan,
Gentleman, 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 improvements in locking devices for tillers of ships,
boats, yachts, and the like enabling the rudder to be set and fixed in any desired
direction without having to be constantly held.
In carrying out my invention I propuse to forin on the under sido of tho tiller an
extension or projection having a hole extending through it parallel with the tiller.
Through this hole is placed a bolt or stop having a tooth or projection formed on
one end of the bolt and engaging with a curved rack fixed by any convenient method
to the sides or deck of tho boat or yacht.
This bolt is actuated by means of a lever connected to the handle or to any other
suitable part of the tiller.
In order that the invention may be clearly understood reference is had to the
accompanying sheet of drawings in which
Fig. 1 shows an elevation of the tiller with the fixing device applied. Fig. 2
shows a plan of same.
Figs. 3 and 5 showing details and
Figs. 6 and 7 showing slightly modified forms.
Referring to Figs. 1 and 2 the tiller A is provided with an extension a having a
hole which may be square or round in cross section as shown in Figs. 3 and 4,
formed through it, parallel with the tiller. A bolt or stop B fits into this hole and
is formed with a tooth or projection b engaging with the curved rack C. The
tooth band the teeth o on the rack C are reduced at their points almost to a sharp
edge allowing the former to engage with the latter easily.
The other end of the bolt B is connected by a lever D to the bandle E suitable
binged joints being provided.
The handle E is hollowed or recessed and fits over the end of the tiller which is
of square or rectangular shape to prevent rotary motion of the handle. A collar a'
is fixed to the tiller between the handle and the ring or loop and is connected to
the handle by means of the short connection e' allowing the handle to move a short
distance until the ring or handle stops against the collar. To fix the tiller when
desired the handle is pressed over the tiller when the lever connected to the handle
moves the bolt towards the rack the tooth of the bolt engaging with the teeth in
the rack and thereby fixing it. To release the tiller for purposes of steering the
handle is pulled outwards disengaging the tooth and leaving the tiller free.
To prevent the bolt securing the tiller from becoming disengaged due to any
upward motion of the latter a stop or projection a is provided on the extension a
of the tiller engaging in a slot or groove c' formed immediately underneath and in
conjunction with the rack as shown in Fig. 5 thus any tendency of the tiller to rise
is prevented.
The curved rack C may be attached to the stern of the vessel by means of posts
or pillars & formed or fixed to the ends of the rack.
In the case of insufficient room the rack may be bolted or otherwise fixed direct
to the deck.

page_text: In the modification shown in Fig. 6 a rod F is employed having collars f fixed
to it stopping against an extension A' on the tiller and allowing of a short relative
notion to the latter, the bolt being connected by means of a lever as in the previous
cases. A small handle is employed for actuating these parts..
As shown in Fig. 7 a small lever G is used being pivoted to an extension A' on
the tiller so that on being pulled upwards causes the tooth on the bolt connected by
a connecting rod D to enter the rack thereby fixing the tiller, and rudder.
To apply this invention to existing helms metal clips may be employed as shown
in Figa. 6 and 7 being formed in pieces and fixed together by means of screws or
bolts or nuts or in any other suitable manner.
Having now particularly described and ascertained the naturo of my said inven-
tion and in what manner the same is to be performed, I declare that what I
oldim is :-
1. Improvements in locking devices for tillers the combination of a sliding handle
connected by suitable connections to a bolt substantially as described and for the
purposes specified.
2. Improvements in locking devices for tillers the combination of a sliding
handle moving between stops, of a bolt having a tooth or teeth engaging with a
rack substantially as described and for the purposes specified.
3. Improvements in locking devices for tillers the combination of a bolt engaging
with rack attached or fixed to the deck or other convenient part of a boat yacht
and the like actuated by means of lovers or handles substantially as described and
shown in the accompanying sheet of drawings and for the purposes specified.
Dated this 26th August 1896.
