COMPLETE SPECIFICATION,
An Improved Compensator for Undue Strains on Ships' Cables and
Towing Hawsers.
We EDMUND AUGUST EDWARD FINCKENSTADT Sugar Manufacturer and GEORGE
Roy Accountant both of Sydney in the Colony of New South Wales 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 has been devised in order to produce an apparatus appliance or
improved compensator which will take up any excessive strain or pull upon the
cables of ships &c. when riding at anchor and upon the hawsers between ships and
tugs during towing. By its use the strain is minimised to that which the cable or
the hawser will stand, and the danger of sudden jerks or shocks upon such cables or
hawsers is prevented and an even or steady pull or hold is maintained.
hawsers is
This improved compensator for undue strains on ships cables or
constructed by threading a spring or springs or other compressible elastic means over
an eye bolt within a brace or shackle the eye bolt and the end of the shackle farthest
from it taking ends of the cable or hawser parted for the purpose. The springs or
other compressible elastic matter are contained within a casing to which the shackle
is bolted. A washer on the eye bolt takes against the end of the spring farthest from
the eye and is adapted to travel in said casing of the springs. A second spring or
elastic washer is inserted over the eye bolt between the end of the shackle and the
eye outside of the casing to maintain the compensator in the normal position of
greatest length.
But in order that this invention may be clearly understood reference will now be
made to the drawings herewith in which Figures 1. 2. 3 and 4 are sectional elevation
plan side view and end view respectively of our improved compensator and Figures 5
and 6 are sections on lines a a and b b respectively in Figure 1 while Figure 7 is
an elevation of a shackle connection to eye bolt. A is eye bolt or pull rod. B brace
or shackle. C springs. D casing. A* is shackle connection. A¹ eye. A pin.
A cotter or split pin. A collar. A short or outside spring. A washer. A nut
and split pin. B₁ bored cross head. B semicircular round end. B2 bolt holes.
C¹ iron washers. Cleather washer. D' end plate. D² studs. D lugs. D bolts
or studs. De snug. E is plank foundation or planking of deck.
In use the shackle B and casing D is fastened to the deck or a solid part of the
ship by bolts D through lugs D and holes B in a convenient position, and when
towing the round end B' of shackle B is firmly attached to a towing post or other
fixture while the hawser is attached to shackle connection A*. The spring A³ will
keep the compensator at its extended length and when the strain of towing comes
upon the hawser the springs C are compressed by the bolt A pulling the washer A*
in the casing and against said springs to the desired extent but when undue strain
comes upon the hawser the springs C are further compressed and storing up the force
gives it out again upon the release of said undue strain by extending said springs to
the extent of the towing strain. When a ship is riding at anchor the use and opera-
tion of the compensator with one end of the cable attached to shackle connection A×
and the round end B of shackle B firmly fixed to the ship's deck or fittings thereon
is exactly the same as in towing.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
