Improvements in Anchors.
I WILLIAM THOMAS HONESS of Nos. 43 and 45 Beresford Street Walworth
London S.E. 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 :-
My invention relates to anchors of the class known as "self canting anchors"
and it consists of certain improvements in the construction of such anchors i.e., by
doing away with bolts pins cotters side plates box beads, &c., which are subject to
strain and liable to have their action interfered with either by earth rubble or
sand.
My said invention will admit auchors of this class to be made with increased
bearing surfaces they having much greater holding power and durability compared
with other anchors and can be used with or without the stock, or what is known, as
the steadying arms; and in addition, it will possess increased facilities for stowing-
thus meeting the present market requirements in respect of stockless anchors.
No part of the said anchor can foul the cable as the form of construction of
sbank flukes and stock render same simply impossible.
The scientific construction of this anchor is such that it can be manufactured
30 per cent. cheaper and 30 per cent. stronger.
My improvements relate specially to anchors such as are described in Specification
No. 19272 of November 7th 1891 and introduce great simplicity namely, a blade
and shoulder which represent the best strain resisting force known in engineering,
giving at once the muximum amount of strength that it is possible to devise.
In the centre of the bend or fluke piece is the said blade which is made to move
in an upward or downward direction, thus, giving the flukes in each position an
angle of 42 to 50 degrees, and resisting any possible amount of strain, the blade or
stop being in the centre of the flukes or bend, which said flukes or bend pass into
the head of the shank of the anchor and its movement to the extreme angles on
either side is regulated by the said shoulder which passes as aforesaid entirely
through the said shank head and the fluke or beud is kept in place and position by
an iron plate which is passed into the said shank head.
My improvements are also an introduction of jackets one of which being laid on
or sunk and keyed to each side of the shank head of anchor with buoying shackle
pin passing through each jacket, thus, keeping the blade firmly secured entirely
covered and free from any possible obstruction in its action.
That the action of the flukes with the blade or stop in the centre. is made to
work in an upward or downward direction as aforesaid!
When the shank head of my improved anchor receives the blade or stop in
position the blade as aforesaid will be entirely covered and the said flukes or palms
being made of increased width gives much greater holding power with no risk of
the flukes or palms breaking off or even bending at the points.
The stock or steadying arms are made to the plan of the palms or flukes and of
a width a little less than the space between the palms or flukes so as to avoid any
possible interference with the action of the fluke points the remaining parts of the
anchor are made or constructed in every way usual in anchors of the said class or
lescription.
Figures 1 and 2 in the accompanying drawings show the side and front elevations
if my commitato anchon

page_text: Figure 3 shows the side elevation of the shank heads by themselves.
Figure 4 shows the front elevation of the cross or fluke piece with the blade or
stop E in the centre thereof.
Figure 5 shows side view of the palm or fluke piece A with section of blade or
stop E.
Figure 6 shows elevation of jackets and square head keys for same.
Figures 7 and 8 show plates H and shackle pin for shank head.
Figures 9 and 10 show on an enlarged scale a front and side elevation of anchor
shank D with plate H and jackets I in place.
In my anchor as shown in the said drawings the centre of the cross or fluke
piece A turns in the opening B in an upward or downward direction which
represents the shoulder formed in the head C of the shank D and its movement to
either side is regulated by the said shoulder B giving the fluke piece A an anglo
of 42 to 50 degrees which permanently and effectually stop the action of the cross
or fluke picces at the extreme angles F.
The cross of the fluke piece A is secured in its position and steadied in its action
by the plate H in shank head.
Figure 6 represents the jackets which are secured by square head keys and
buoying shackle pin passing through the plate and jackets I and by so doing it
resists any strain and cannot be dislodged from its place or sheared off by the
action of the cross A or fluke piece J which are made of increased thickness and
width. Consequently they are of increased power and strength and with a greater
area or surface of resistance, thus, as stated, there being no risk of the cross A or
fluke piece J breaking or bending at the points, the stock or steadying arms K are
made to the plan of the cross A or fluke piece J, and of width slightly less than
the space between the points of the cross A or fluke piece J 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 general construction arrangement, and combination of parts, constituting my
anchor are herein before substantially described and illustrated in the accompanying
drawings.
Having now particularly described and ascertained the nature of my "said
improvements and invention and in what manner the same are to be performed I
declare that what I claim is
(1.) The introduction of an upward and downward' action of the flukes regulated
by the action of the blade or stop also of jackets to cover the blade or stop and
recess as described and illustrated in the accompanying drawings, in the centro, of
the fluke piece which revolves in a recess cut in the centre of the shoulder of the
shank head and with the plate let into the shank head for the purpose of steadying
the action of the flukes as introduced by George Harden Langley and William
Thomas Honess in the construction of their anchor and for which they obtained
Letters Patent dated the 7th day of November 1891 No. 19272.
(2.) The introduction of two jackets as described and illustrated in the accom-
panying drawings (one placed on each side of the shank head and secured by pins
or keys) for the purpose of covering over the said blade or stop and recess and
which is hereinbefore fully set forth in the description of my invention and which
is also fully illustrated by the accompanying drawings.
(3.) And I further claim to bave my said anchor constructed as a stock or
stockless anchor with rounded or square shank head.
