HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVE-
MENTS IN DEAD-EYES AND ROPE ATTACHMENTS." A communication from abroad
by William Pickering Healey, of the State of Massachusetts, of the United States
of America.
The nature of the said Invention consists,―
Firstly. In a dead-eye cast of metal in one piece, and provided with a chamber,
rope-eyes, and their terminal grooves.
Secondly. In a dead-eye cast of metal in one piece, and provided with rope-cyes
and their terminal grooves, and also with a metallic socket-piece, open at one end,
and having a filling inlet at its bottom.
Thirdly. In the socket piece, chambered and open at one end, and provided at.
the other end with a filling inlet, in combination with a wire-rope chambered and
introduced into such socket piece, and with a metallic filling cast through such
inlet, and into such socket piece, and into and around the portion of the rope
therein.
Fourthly. In the socket piece, chambered and open at one end, and provided
with a filling inlet and a metallic core, in combination with a wire rope extended
at one end into the socket piece and chambered to receive the core thereof, and
with a metallic filling cast into the socket piece, and into and around the rope
portion therein and around the core.

HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVE-
MENTS IN DEAD-EYES AND ROPE ATTACHMENTS.' A communication from abroad
by William Pickering Healey, of the State of Massachusetts, of the United States
of America.
The Invention is represented in the accompanying Drawings, of which Figures 1
and 2 are lengthwise sections of a dead-eye and its connected wire rope provided
with my Invention, the nature of which is duly set forth in the claim or claims
hereinafter presented. This dead-eye A is of cast-iron or motal and chambered, as
shown at a, and provided with a tubular socket-piece B. It also has the usual
rope-eyes going through it laterally, each of them at each of its ends
terminating in a downward groove c. There leads from the upper or middle eye b,
or into the socket-piece at its bottom, an inlet or passage d, which, as shown, goes
through the bottom e and into the chamber f of the socket-piece. All of the dead-
eye which is above the chamber a is solid, except in having in it the rope-eyes b
and their terminal grooves c.
The chainber of the socket-piece is open at its outer
end to receive the wire-rope C, which, previous to being inserted in the said chamber
and down or nearly down to its bottom, is to have its hempen heart-strand removed
from the portion of it to go into the chamber, such being to form within the rope
axially thereof a space or chamber g to receive the metallic filling h to be described.
Prior to the insertion of the said filling into the rope and socket-piece, I usually
dip the socket-piece into muriatic acid or a solution thereof, and afterward into
molten tin, in order to cover the inner surface of the socket piece with a thin layer
of tin, which will adhere firmly to the said surface. Having introduced the wire-
rope into the socket-piece, and closed the exterior or outer end of the latter around
the rope with clay or a suitable putty, I cast into the socket piece, through the inlet
or upper eye and the inlet before described, inolten metal or composition, such as is
usually known as "Babbitt metal," such metal filling the space in the rope and
that around it and between it and the inner surface of the chamber of the socket-
piece, and thereby not only fastening the rope firmly to the socket-pieco, but
providing it with a metallic core, which when solidified will prevent the rope from
contracting within the socket-piece and loosening the connection therewith under
strain of the rope.
The chamber in the dead-eye serves to reduce the weight thereof in comparison
to what it would have were it without such chamber.
If desirable the dead-eye, besides its chamber and eyes and their terminal grooves,
may have an annular eye to project from it at its lower end. The socket piece may
also be grooved or indented in its inner surface.
I sometimes provide the socket piece with a metallic core arranged within it
concentrically, and to extend from its bottom into the chamber in the wire rope,
the metal on being cast into such chamber surrounding the said core, which may be
somewhat tapering. The core in such case aids in fastening the rope in the socket
of the socket-piece. Figure 3 is a section of the socket-piece showing the metallic
core, which is inarked k
The dead-eye, chambered as shown, has at the lower part of it an opening leading
out of the chamber, such opening being for discharge of the core from the chamber,
and necessarily formed in the dead-eye by the core supporter. The open chamber,
besides serving to lighten the dead-eye or diminish its weight, can be made to

page_text: answer a useful purpose, viz., to receive the shroud-straining rope at its upper end,
and thereby protect such end, as does the canvas cap or cover usually fixed thereon,
thereby saving all necessity of such a cap or like appliance to the rope.
The dead-eye, as herein described, differs materially from the shroud attachment
shown in the British Patent No. 1888, for the year 1860, as it has the tightening
rope-eyes going through it, and it also has the chamber open at bottom, and
furthermore it has the socket piece with the filling-opening therefrom leading into
the middle-eye, such not being in the said shroud attachment, which is for a common
hempen rope, and not for connection with a rope of twisted wire, as usually made
with a hempen core.
Instead of having the socket-piece and dead-eye cast in one piece, the socket-
piece may be separately constructed, and attached to the dead-eye by bolting or
hinging the two together, or by other convenient or proper means.
1. As an improved article of manufacture, a dead eye cast of metal in one piece,
and provided with the open chamber a, rope-eyes b, and their terminal grooves c,
all substantially as set forth.
2. The dead-eye cast of metal in one piece, and provided with the rope-eyes and
their terminal grooves, and the metallic socket-piece, open at one end, and with
the filling inlet at its bottom, such socket-piece and inlet being for the purpose set
forth.
3. The socket-piece, chambered and open at one end, and provided with the inlet
at the other end, in combination with the wire rope, chambered as described, and
with the metallic filling cast into the socket-piece through its inlet, and into and
around the portion of the rope within such socket-piece, all being substantially as
shown and described.
4. The socket-piece, chambered and open at one end, and provided with the inlet
and metallic core, as explained, in combination with the wire rope, chambered as
described, and with the metallic filling or Babbitting cast into the socket-piece and
into and around the rope and the core, all being substantially as set forth.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
band and seal, this Twenty-third day of December, A.D. 1881.
H. J. HADDAN. (L.S.)
