PROVISIONAL SPECIFICATION.
Certain Improvements in Anchors known as Stockless Anchors.
I, WILLIAM HINDSON Bensham Lodge, Gateshead on Tyne, County of Durham,
Engineer, and Works Manager to Messrs. John Abbot & Co., Ld., Park Works
Gateshead on Tyne, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in anchors known as stockless
anchors, and consists in forming the head or holding arms of the anchor in two
pieces, with the pin or pivot cast or forged on each piece, and having the main
holding arm, the centre or trip arm and the side projecting arm (to prevent rolling)
combined in each piece.
My objects being,-
To obtain a firm solid pin or pivot for the. anchor, cast or forged with, and
forming part of the head pieces, thereby dispensing with loose pins, straps, keys,
bolts, washers and cotters for attaching the head piece to the anchor shank.
To prevent the anchor rolling, by casting or forging projecting side arms on, in
line with the pin or pivot, thereby acting as a stock, and ensuring that the anchor
does not roll over when reaching the ground.
To simplify the construction of the head piece so as to ensure a sound and strong
casting or forging, and consequently a more reliable head piece than when it is
formed in one piece.
To facilitate the carriage or transit of the anchor by having the head and shank
sent away in pieces.
To facilitate and cheapen repairs in case of a broken arm or fluke, by having
the two pieces forming the anchor head, exact duplicates of each other.
The anchor is made of three main pieces, i.e.
The shank, which is of the usual form, made of wrought iron, or steel, having
eye for head pivot forged solid with the shank.
The head, in two pieces, of cast steel, forged iron, or forged steel, with a
projecting pin or pivot formed on each piece, and having ribs or lugs for securing
the two pieces together by means of bolts or hoops.
The head pieces when secured to each other consists of six flukes or arms,-i.e.
two main holding arms,-two centre or trip arms, and two side projecting arms,-
the two side arms being a special feature of this invention, intended to prevent the
anchor rolling over when reaching the ground.

I WILLIAM HINDSON, Bensham Lodge, Gateshead-ou-Tyne, County of Durham,
Engineer, & Works Manager to Messrs. John Abbot & Co., Ld., Park Works
Gateshead-on-Tyne, 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 relates to certain improvements in anchors, known as stockless

page_text: anchors, and consists in forming the head or holding arms of the anchor in two
pieces, with the pin or pivot cast or forged on each piece, and having the main
holding arm, the centre or trip arm, and the side projecting arm or elbow (to
prevent rolling) combined in each piece, my object being,-
To obtain a firm solid pin or pivot for the anchors, cast or forged with and
forming part of the head pieces, thereby dispensing with loose pins, straps, keys,
bolts, washers and cotters for attaching the head piece to the anchor shank.
To prevent the anchor rolling, by casting or forging projecting side arms or
elbows on, in line with the centre pin or pivot, thereby acting as a stock, and
ensuring that the anchor does not roll over when reaching the ground.
To simplify the construction of the head piece so as to ensure a sound and strong
casting or forging, and consequently a more reliable head piece than when it is
formed in one piece.
To facilitate the carriage or transit of the anchor by having the head and shank
sent away in pieces if so required.
To facilitate and cheapen repairs in case of a broken arm or fluke, by having the
two pieces forming the anchor head, exact duplicates of each other.
The anchor is made of three main pieces, namely
The shank, which is of the usual form made of wrought iron or steel, having
eye for head pivot pin forged solid with the shank.
The head, in two pieces, of cast steel, forged iron, or forged steel, with a
projecting pin or pivot, formed on each piece, and having flanges or lugs for securing
the two pieces together by means of bolts with ends clunk over.
The head pieces when secured to each other consist of six flukes or arms,
namely, two main arms, two centre or "trip" arms, and two side projecting arms
or elbows, the two side arms being a special feature of this invention, intended to
prevent the anchor from rolling over when reaching the ground thereby acting as a
stock to the anchor.

In order that my invention may be fully understood I shall now proceed more
particularly to describe the same, and for that purpose shall refer to the several
figures and letters in the annexed sheet of drawings, the same letter of reference
indicating corresponding parts in all the figures.
Figures I, II, III, represent the anchor in its complete form, with the two pieces
forming the head, secured together.
Figures IV, V, represents each half of the head piece.
Figure VI, represents a section of the shank and head pieces, showing how they'
are secured to each other.
Letter A, represents the two pieces forming the head.
Letter B, represents the anchor shank.
Letter C, represents the main holding arms or flikes.
Letter D, represents the flanges for securing the two head pieces to each other
and the two centre or "trip" arms combined.
Letter E, represents the side projecting arms or elbows to prevent rolling and
answering the purpose of a stock.
Letter F, represents the centre pin or pivot to which shank is attached.
Letter G, represents the buoy shackle.
Letter H, represents the bolts rivetted over securing the two pieces forming the
head of the anchor.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,--
To form the head or holding arms of the anchor in two pieces with the pin or
pivot cast or forged on each piece, and having the main arm, the centre or trip arm,
and the side projecting arm or elbow (to prevent rolling) combined in each piece,-
thereby obtaining a firm solid pin or pivot, forming part of the head piece and

page_text: dispensing with loose pins, straps, keys, bolts, washers, and cotters for attaching
the head piece to the anchor shank, also preventing the anchor rolling on reaching
the ground, by means of the side projecting arms or elbows acting as a stock on the
head piece.
