PROVISIONAL SPECIFICATION.
Improvements in Anchors.
We GEORGE HARDEN LANGLEY of 25 Rattray Road, Brixton London, Marine
Engineer, and WILLIAM THOMAS HONESS of 43 Beresford Street, Walworth,
London Civil Engineer do hereby declare the nature of this invention. to be as
follows:-
}
Our invention relates to anchors of the class known as Martin anchors and it
consists of certain improvements in the construction and manufacture of such
anchors by doing away with pins keys, bolts, cotters, side plates and box-heads
subject to strain and liable to have their action interfered with by earth or sand.
Our invention enables anchors of this class to be made with increased bearing
surfaces they are of greater holding power, strength and durability and they can
be used with or without the stock or steadying arms to meet the present market
requirements, they also possess increased facilities for stowing, and no part of the
anchor can foul the cable, they are simple of construction and they can be made
much better and cheaper than hitherto.
In an anchor made with our improvements the centre of the cross or fluke piece
turns in an opening or round eye formed in the head of the shank and its move-
ment to either side is regulated by two shoulders at the centre of the fluke on
the outside. The two shoulders work in a recess extending either partly or right
across the opening.or eye of the shank head, and they permanently and effectually
stop the action of the flukes at the extreme angle, the flukes being steadied in
their movement and kept in their position by means of a pin passing through the
back of the shank head and between the two shoulders; the recess in the shank
enables the arms to be made square and the palms also to be made of increased
width and of greater power and strength with no risk of the flukes breaking or
bending at the points. The stock or steadying arms are made to the plan of the
flukes and of width slightly less than the space between the palms of the flukes so
as to avoid any possible interference with the action of the fluke points. The
remaining parts of the anchor. or parts connected therewith are made or constructed
in,any suitable way usual in anchors of the class or description.

Improvements in Anchors.
We GEORGE HARDEN LANGLEY of 25 Rattray Road, Brixton, London, Marine
Engineer, and WILLIAM THOMAS HONESS of 43 Beresford Street, Walworth,
London, Civil Engineer 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 said invention relates to anchors of the class known as Martins anchors
such as are described in the Specification of Letters Patent granted to Claude
Martin and Hyppolite Martin and dated the 30th May 1872 No. 1632.
The object of our invention is to improve the construction and increase the
efficiency of such anchors whereby they are made with increased bearing surfaces
and over-all dimensions offering greater resistance and strength with increased
durability and extraordinary holding power combined with diminished weight. Our
said invention also enables anchors of this class to be used with or without the
stock or steadying arms thereby offering increased facilities for stowage, no part
of the anchor can foul the cable, and the anchor with our improvements is simple
of construction and can be easily and cheaply made.
In order that our invention may be fully understood we shall now proceed more
particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figures 1 and 2 are side and front elevations of the complete anchor,
Figure 3 side elevation of the shank head by itself,
Figures 4 and 5 front and side elevations of the cross or fluke piece by itself,
and
Figures 6 and 7 front and side elevations of the pin or plate by itself.
In the anchor shown in the drawings the centre of the cross or fluke piece "A"
turns in an opening or round eye "B" formed in the head "C" of the shank "D"
and its movement to either side is regulated by two shoulders "EE" at or about
the centre of the cross or fluke piece on the outside, the two shoulders work in a
recess "F" extending right across the opening or eye of the shank head, the two
shoulders permanently and effectually stop the action of the cross or fluke piece
at the extreme angle, the cross or fluke piece is secured in its position and
steadied in its action by the pin or plate "G" through the back of the shank
head and between the two shoulders, there is no strain upon the pin or plate
and it cannot be dislodged from its place or sheared off by the action of the cross
or fluke piece, the pin or plate is secured and kept in its place by a cross pin H
through the buoying shackle "I" and the shank head, the palms "J" of the cross
or fluke piece are made of increased thickness and width consequently of increased
power and strength and with a greater area or surface of resistance, there is no
risk of the cross or fluke piece breaking or bending at the points, the stock or
steadying arms "K" are made to the plan of the cross or fluke piece and of
width slightly less than the space between the points of the cross or fluke piece
so as to avoid any possible interference on the part of the stock or steadying arms
with the action of the fluke points when taking the ground, the remaining parts
of the anchor are constructed in the usual manner in anchors of the class or type.
"
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. In anchors of the class or type referred to, a recess in connection with the
opening or round eye in the shank head extending the full width or thickness of
from side to side of the shank head, the said recess for receiving the two shoulders or

page_text: projections on the cross or fluke piece, substantially in the manner described and
illustrated in the accompanying drawings.
2. In anchors of the class or type referred to constructing the cross or flako
piece with the two shoulders, and the improved construction of the palms of the
eross or fluke-piece, also the regulating and securing of the cross or fluke piece by
the pin or plate through the back of the shank head and between the two.
shoulders, and the securing of the pin or plate by a cross pin through the buoying
shackle plate and shank head substantially in the manner and form and for the
purposes hereinbefore described and as shown in the drawings.
3. In anchors of the class or type referred to the improved construction of the
stock or steadying arms substantially in the form and for the purposes hereinbefore
described.
4. The general construction arrangement and combination of parts constituting
an anchor substantially as hereinbefore described and illustrated in the accom-
panying drawings.
