PROVISIONAL SPECIFICATION.
An Improved Device or Appliance for Relieving the Strains on
Ships' Shrouds or Rigging.
We, JOE HERBERT TEALE and JOSEPH EDWARD GOLDEN both of 78 Denmark
Street, South Shields in the County of Durham, Seamen do hereby declare the
nature of this invention to be as follows:-
Our invention refers to an improved device or appliance for relieving the strains
on ships' shrouds or rigging.
According to the most usual system at present in use the end of the rigging is
attached to an eye of a screw bolt working in a socket the latter being arranged so
that the turning of the socket or cylinder by means of a handspike or bar either
shortens or lengthens the length of and consequently increases or decreases the
strain on the rigging. The set of the rigging is thus practically constant or
dependent on the extent of tension put thereon by the boatswain and the object of
our invention is to provide some simple method by which the set aforesaid may to
a certain extent be self-adjustable.
To carry out our invention we arrange between the rigging end and the socket
bolt or the equivalent thereof a cylinder or vessel containing a spring or the like
resilient medium. One end of the cylinder may then be connected to the socket
bolt. Within the cylinder or vessel works a disc or piston or equivalent device
from which a rod passes preferably within the spring towards the rigging. The
end of the rod may be connected to the rigging in any suitable manner.
By the above device the shrouds, stays or rigging can be set up in the usual way
by turning the socket as above described but the spring and piston device enables
a certain amount of automatic lengthening and shortening of the shrouds stays or
rigging to take place as required which greatly relieves the strain thereon thus
economising the rigging and adding to the safety thereof.
The cylinder may be made in two halves and bolted together.
Lubrication and drainage may also be provided for by slits or holes as
required.

COMPLETE SPECIFICATION.
An Improved Device or Appliance for Relieving the Strains on
Ships' Shrouds or Rigging.
We, JOE HERBERT TEALE and JOSEPH EDWARD GOLDEN both of 78 Denmark
Street, South Shields, in the County of Durham, Seamen 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:—
Our invention refers to an improved device or appliance for relieving the strains
on ships' shrouds or rigging.
According to the most usual system at present in use the end of the rigging is
attached to an eye of a screw bolt working in a socket the latter being arranged so
that the turning of the socket or cylinder by means of a handspike or bar either
shortens or lengthens the length of and consequently increases or decreases the

page_text: strain on the rigging. The set of the rigging is thus practically constant or
dependent on the extent of tension put thereon by the boatswain and the object of
our invention is to provide some simple method by which the set aforesaid may to a
certain extent be self-adjustable.
To carry out our invention we arrange between the rigging end and the socket
bolt or the equivalent thereof a cylinder or vessel containing a spring or the like
resilient medium. One end of the cylinder may then be connected to the socket
.bolt. Within the cylinder or vessel works a disc or piston or equivalent device
from which a rod passes preferably within the spring towards the rigging. The
end of the rod may be connected to the rigging in any suitable manner.
By the above device the shrouds, stays or rigging can be set up in the usual way
by turning the socket as above described but the spring and piston device enables
a certain amount of automatic lengthening and shortening of the shrouds, stays or
rigging to take place as required which greatly relieves the strain thereon thus
economising the rigging and adding to the safety thereof.
The cylinder may be made in two halves and bolted together.
Lubrication and drainage may also be provided for by slits or holes as
required.
We will fully describe our invention with reference to the accompanying drawings
in which
Figure 1 is a sectional elevation and Figure 2 a side view at right angles to the
view shown in Fig. 1.
Like letters indicate like parts throughout the following description.
Referring to the figures, 1 is a steel cylinder cast preferably in halves with lugs
thereon and bolted together at 2 as shown. A lug or extension 3 on one end of the
cylinder is shown connected to the double eye of the tightening up or screw socket
bolt 4. Within the cylinder is a disc or piston 5 with rod 6 passing therefrom and
terminating in an eye for attachment to the rigging 7 as shown. 8 is the spring
which normally abuts against the end.9 of the cylinder. Small slits or grooves 10
may be provided to allow any water to run out of the cylinder which may be
lubricated through small holes 11 provided in the cover for this purpose.
Shrouds, stays or rigging can thus be "set up" in the usual way by turning the
socket as above described but the spring and piston device arranged as shown
always enables a certain amount of automatic or resilient lengthening and
shortening of the rigging to take place as required which has the effect herein
above described.
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 :-
1. For relieving strains on ships' shrouds or rigging the interposition between
the rigging and its point of attachment or setting up or tightening gear of a
cylinder containing a spring and piston device the rod of which is connected to the
rigging the several parts being arranged with respect to one another and operating
substantially as and for the purpose herein set forth.
Dated this 29th day of June 1891.
