COMPLETE SPECIFICATION:
An Improved Attachment for Cables to Submarine Mines, which
Attachment is also applicable for Attaching any Ropes or
Cables.
We JOHN STEPHENS and ARCHIBALD STEPHENS both of the Upper Back
Works Pembroke in the County of Pembroke Mechanical Engineers 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 proposed invention which is designed more especially for the purpose of
connecting electric cables from batteries on shore with submarine mines and which
may be used for attaching any ropes or cables consists of an attachment constructed
preferably of metal made in two parts hinged together at one end and closed at
the other by means of a moveable bolt and nut. The bolt is hinged on a side of
one of the parts and when the attachment is closed it swings into a slot on the
other part of the attachment where it is secured by a nut which fits into a recess
and prevents the bolt falling out of place if the nut becomes partially slacked.
In the centre of one part of the attachment there is a grooved stud for the
purpose of receiving a bight of the cable which cable lies in grooves formed in the
interior surfaces of the two parts and then passes out through bell mouthed
openings. When the bight of the cable has been placed in the manner before
described the two parts of the attachment are closed together and bolted and the
required position on the cable is thereby secured.
A ring on one of the parts of the attachment enables the attachment to be
affixed to any required object.
And in order that our said invention may be properly understood we now
proceed more particularly to describe the same with reference to the accompanying
drawings and the figures and letters marked thereon.
Figure 1 on the drawings represents in plan the attachment opened for the purpose
of receiving the cable ZZZ.
A and B represent the two parts hinged together at C.
D represents the bolt hinged at E.
F represents the nut which when A and B are closed falls into the slot G.
H represents the grooved stud around which the bight of the cable ZZZ is
passed.
The cable Z Z Z lies in the grooved channels KKK represented in Figures 1
and 2.
Figure 2 on the drawings represents in plan the attachment closed after receiving
the cable and secured by the bolt D and nut F.
The ring M in both figures is for affixing the attachment and cable to any
requisite object.
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 and what we
claim is
1. That the attachment enables a coil of cable to be speedily and accurately
placed in the proper and requisite position with reference to the purpose for which
it is to be used without the necessity of reeving the cable through the
attachment

page_text: 2. That the attachment places the cable in the most favorable position to resist
strains.
3. That the bell mouthed openings M M minimise the liability of the cable to
injury by chafing.
4. That the attachment is perfectly rigid and has no loose detachable parts.
5. That the attachment is light in construction and of great holding power.
