Improvements in Apparatus for Protecting Rudders and Steering
Ropes from Injury.
Communicated to me from abroad by MICHEL TIMONI, of Marseille, in the
Republic of France, Engineer.
I, EDMUND EDWARDS, of the firm of Edwards and Co. Patent Agents and Engineers,
of 35 Southampton Buildings, Chancery Lane, in the County of Middlesex do hereby
declare the nature of this invention to be as follows:
This invention has for its object improvements in apparatus for protecting the
rudders and steering ropes of ships of all kinds from injury, by the blows of waves,
and it consists of a strong helical spring surrounded by four longitudinal bolts. The
spring abuts at one end against a plate through which passes a central screwed bolt
provided with a brass nut, by which its tension can be regulated; and at the other
end against a support provided with a strong loop by which the apparatus is connected
to the steering rope by a knot or other fastening or coupling.
The first described support or plate is traversed by the four longitudinal bolts, and
by extensions of the ends of the loop already described; the other support is traversed
by the same longitudinal bolts, and by the central screwed bolt already described.
The four longitudinal bolts carry at one end a connecting plate, and at the other
end they are fixed to a similar connecting plate having a central boss screwed to
receive a right and left handed screwed coupling; a third connecting plate or ring
is arranged between the two already described, and is kept in its place by tubes
surrounding the longitudinal bolts, and this last ring carries an outer movable tube,
which serves as a case or sheath to the apparatus.
The coupling consists of a right and left handed screw having a central boss with
holes by which it can be turned round. One end is screwed into the boss already
described, and the other end into a nut by which it is connected to the other part of
the steering rope. The apparatus is arranged as near as possible to the rudder.
From the elasticity of the apparatus described, it will be readily understood that
any injurious effects which might be produced upon the steering ropes or tiller by
the waves when heavy seas are running, or by rapid movement of the ship are
prevented. It may be arranged in any convenient position with regard to the rudder,
and the steering ropes may be kept tight by means of the right and left handed
coupling screw, which forms part of the apparatus, but is independent of the part
containing the spring.
The spring may be helical of square or round steel, or in the form of plates, or of
indiarubber suitably arranged, and the outer tube or case may be of any suitable
metal.

Improvements in Apparatus for Protecting Rudders and Steering
Ropes from Injury.
A communication to me from abroad by MICHEL TIMONI, of Marseille, in the
Republic of France, Engineer.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of Middlesex,
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 and accompanying drawings, that is to say :-
This invention has for its object improvements in apparatus for protecting the
Price 6dl

page_text: rudders and steering ropes of ships of all kinds from injury by the blows of waves
upon the rudder.
The accompanying drawings are in illustration of the invention. Figure 1 is an
elevation of the apparatus, Figure 2 is a plan of Figure 1, the cover being shewn in
section. Figures 3 and 4 are end views. In sheet 2 some of the parts are shewn
in detail. The same letters indicate the same parts in the several figures.
The apparatus consists of a strong helical spring A, surrounded by four longitudinal
bolts B. The spring A abuts at one end against a plate C through which passes and
is fixed a central screwed bolt D provided with a brass nut E, by which its tension
can be regulated; and at the other end against a support F through which passes a
strong loop G by which the apparatus is connected to the steering rope by a knot or
other fastening or coupling. In the drawing a fork 'L is shewn through which passes
a pin to which the rope is connected.
The first described support or plate C is traversed by the four longitudinal bolts B
and by extensions of the ends of the loop G already described; the other support F,
is traversed by the same longitudinal bolts, and by the central screwed bolt D already
described.
The longitudinal boits B carry at one end a connecting plate H, and at the other
end they are held by a similar connecting plate I having à central boss screwed to
receive a right and left handed screwed coupling K by which the fork L and the
plate I can be drawn together or separated; a third connecting plate or ring J is
arranged between the two already described, and is kept in its place by tubes
surrounding the longitudinal bolts B, and this last ring J has a shoulder which
carries an outer moveable tube N, which serves as a case or sheath to the apparatus.
The coupling K consists of a right and left handed screw having a central boss
with holes by which it can be turned round. One end is screwed into the boss on I
already described, and the other end into a nut or boss of the fork L by which it is
connected to the other part of the steering rope. The apparatus is inserted into
the steering rope or chain on both sides and arranged as near as possible to the
rudder.
From the elasticity of the apparatus described, it will be readily understood that
any injurious effects which might be produced upon the steering ropes or tiller by
the waves when heavy seas are running, or by rapid movement of the ship are
prevented. It may be arranged in any convenient position with regard to the rudder,
and the steering ropes may be kept tight by means of the right and left handed
coupling screw, which forms part of the apparatus, but is independent of the part
containing the spring.
The spring may be helical of round or square steel, or in the form of plates, or of
indiarubber suitably arranged, and the outer tube or case may be of any suitable
metal or material. The apparatus is applicable to ships or steam vessels of all kinds
and sizes, and may be modified more or less according to the conditions and
circumstances in which it is to be used.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is :—
1. The combination of the spring A, bolts B, plates C and F, central bolt D and
nut E, and plates I and H, arranged and operating substantially as and for the purpose
described and shewn.
2. In combination with the apparatus described and claimed in claim 1, the loop G,
right and left handed connecting screw K, and loop L, substantially as and for the
purpose described and shewn.
3. The outer case N, surrounding the spring A, substantially as described and
shewn.
