IMPROVEMENTS IN SHIPS' ANCHORS
Year: 1884

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN SHIPS' ANCHORS" 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 anchors and comprises an anchor having a shank with
a bifurcated crown, two flukes connected by a yoke integral with the same, and an
axial bolt which, passed through ears of the crown and Bukes, connects the flukes
and shank, thus producing a strong and serviceable anchor.
It also comprises an anchor having a yoke the exterior face of which is rounded.
It also comprises an anchor having a yoke, the front or top face of which is
broadened and the outer edge of which is angular, the yoke so projecting beyond
the crown of the shank as to strike the bed of the water in advance of the shank,
then roll on its rounded face and right the anchor, and finally present its broad face
so as to engage with the bottom or bed of the water or obstructions thereon,
thereby depressing the flukes and causing the bills thereof to penetrate the ground
and the consequent burying of the flukes.
In the accompanying drawing
Figure 1 is a side elevation and
Figure 2 is a plan of an anchor embodying my invention.
Figure 3 is a side elevation shewing the anchor engaged, the crown axial bolt,
and part of the shank being in section.
Figure 4 is a view of the crown end thereof.
Similar letters of reference indicate corresponding parts in the several figures.
A represents the shank of an anchor, and B the pivotted flukes, C the yoke and
D the bolt thereof, The said bolt is independent of the flukes and shank and
connects the same; said shank having a bifurcated crown E, the ends of which
are formed with ears F, the ends of the flukes opposite to the bills having ears G,
whose openings coincide with those of the ears F, whereby the bolt D is passed
through both sets of ears and forms the axis of the flukes.
•
The yoke C is of double arch shape, and connects the flukes B, it being noticed
that the bifurcated end or crown of the shank occupies a position within said yoke,
and the latter has its exterior face rounded, as at a, from what may be termed the
front or top of the yoke to the rear or bottom thereof, according to the position of
the anchor, and the front or top face is broadened or flattened, as at b, the outer
edge thereof being sharp or angular, as at c.
It will also be noticed that the yoke is formed as a continuation of the flukes or
integral therewith, of cast or wrought metal, by which provision the yoke possesses
great strength and is not liable to spread or break. Furthermore, when the anchor

page_text: is engaged, the yoke abuts against the shank and receives the strain imparted to
the yoke. The bolt also receives the strain imparted to the crown of the anchor,
and as said bolt connects both sets of ears F, G, and is made somewhat heavy, the
crown possesses strength and durability.
When the anchor is lowered, the rounded face a, of the crown first strikes the
bed of the water, and thus the anchor rolls on the crown throwing both flukes on
the bed or bottom. Should the narrow sides of the palms of the flukes strike the
bed, the anchor will roll sideways and then continue its motion on the crown, thus
righting itself. As the anchor is dragged forward, the lower edge or angle c of the
crown offers resistance thereto, and when it meets with an obstacle, the latter forms,
in a measure, a fulcrum, whereby the flukes are depressed and their bills forced
into the ground, thus causing the flukes to take firm hold thereof and burying the
same.
The bolt D is secured by a nut or cap H, which is prevented from displacement
by means of a key J, passed through said nut and bolt, and as an additional
security I pass through the bolt adjacent to an car F, a key K which serves to
retain the bolt should the nut or cap H be displaced; it being noticed that the
cap H and keys J, K, are fitted to said bolt, so that should the cap H be lost, the
head of the bolt and the key K will retain the bolt in position and prevent dis-
connection of the shank and flukes.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
First. An anchor having a shank with a bifurcated crown and ears on the latter,
flukes with ears, a bolt passing through the eyes, and a double arch shape yoke
which is formed integral with the flukes, substantially as, and for the purpose, set
forth.
Second. In an anchor, a yoke connecting the flukes formed integral therewith,
and having its external face rounded as at a, substantially as, and for the purpose,
set forth.
Third. In an anchor, a yoke connecting the flukes formed integral therowith, and
having its external face rounded as at a, the front or top face broadened as at b,
and angular as at c, substantially as and for the purpose, set forth.
Fourth. An anchor having a shank, flukes pivoted thereto, a bolt connecting the
shank and flukes, and fastening devices for the bolt, consisting of the nut or cap
and keys, substantially as, and for the purpose, set forth.
Fifth. An anchor having a shank A with a bifurcated crown E, flukes B pivoted
thereto, a yoke C connecting said flukes, and a bolt D, said bolt connecting the
flukes with the bifurcated crown of the shank, said yoke and both flukes being
integral, and said yoke having its external face rounded as at a, substantially as,
and for the purpose, set forth.
Sixth. An anchor having a shank A with a bifurcated crown E, flukes B pivoted
thereto, a yoke C connecting said flukes, and a bolt D, said bolt connecting the
flukes with the bifurcated crown of the shank, said yoke and both flukes being
integral, and said yoke having its external face rounded as at a, the front or top
face broadened as at b, and the edge angular as at c, substantially as, and for the
purpose, set forth.
