page_text: I, THOMAS ELI NORTON, of 34, Hartington Terrace, Brockhurst, in the County of
Hunts, Smith and Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to anchors and more especially to those of that kind
commonly called "stockless anchors," and my said invention comprises the improve-
ments hereinafter sot forth.
According to my said invention I provide at each end of the shank or stem of the
anchor a hole or eye to receive a bolt by which a suitable D or shackle can be
secured to the said stem in the usual or ordinary manuer, the said holes or eyes and
dees or shackles being preferably arranged at right angles to one another. Near
one of the above mentioned holes or eyes I provide au enlargement or swelling
having a third hole or eye therein, which latter is preferably at right angles to the
hole or oye receiving the bolt of tho D or shackle at that end. The hole or eye in
the said swelling or onlargoment is slotted at each side to receive a tumbler or
piece which forms a stop or catch to limit the movement of the flukes as heroinafter
mentioned,
The flakes are formed separate, and the top portions or blades thereof preferably
in the form of arrow or spear heads, the opposite or other ends of each of them
having a cylindrical reduced portion adapted to fit iuto, and rotate freely in, the
hole or eye in the beforementioned enlargement or swelling, and terminating in a
square or other suitably shaped part or portion adapted to fit in a correspondingly
shaped hole or recess formed in the central boss or portion of the herein before men-
tioned tumbler or piece and secured or fixed therein by means of screws, pins, keys or
The tumbler or piece is provided with
cottars, or in any other convenient manner.
two oppositely extending tapering or other teeth or projections which can turn or
nove in the slots in the swelling or enlargement, through a certain angle in oither
direction, the latter being so adjusted that the flukes can also turn or pivot there-
with in either direction to a suitable inclination or angle relatively to the shank or
stom and thereby enable the anchor to bite or take the necessary hold upon the
gronnd.
It will be seen that my improved anchor is so constructed that the flukes can be
very readily disconnected from the shank or stem, thereby greatly facilitating tho
stowage thereof for storing or transport.

page_text: I, THOMAS ELI NORTON, of 34, Hartington Terrace, Brockhurst, in the County of
Hants, Smith and 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 and comprises the improvements hereinafter set
forth.
In the accompanying drawings,
Figure 1 is a plan, and
Figure 2 is a side elevation showing an application of my said improvements to a
"stockless" anchor.
Figure 8 is a plan, and
Figure 4 is a side elevation on a reduced scalo, of part of a similar anchor, but
with a "stock" applied thereto.
Like letters indicate corresponding parts throughout the drawing.
a is the shank or stem of the anchor which may, as shown in Figures 1 and 2, be
provided at each end with a hole or eye to receive a bolt g or by which a suitable
shackle e orf can be socured to the said shank, the said holes or eyes and shackles
being preferably arranged at right angles to one another as shown in the
drawing.
According to my invention the shank a is provided with a boss, enlargement, or
swelling a³. This boss has an opening a running entirely through it; and it is
slotted, as shown at a', at right anglos to the opening a*. It will be seen that the
two opposite sides of the slot a¹ incline towards each other and the two inclined
walls of each side meet at the point n². The opening a is intended to recoive
flukes b, and the slot a¹ to receive a tripping-piece c. This tripping-piece is made
in a form approximating to a double wedge; it is an oasy fit within the above
mentioned slot a¹ and is provided with an opening in line with the one a in the
shank a and with two openings to receive bolts d, one on either side.
The flukes b, b are formed separate, and preferably with the blades thereof in the
form of arrow or spear heads as shown. Each fluke has a reduced portion b¹
adapted to fit into, and rotate freely in, the opening a**, whilst they each
terminate in a square or other suitably shaped part or portion 6* adapted to fit in
the correspondingly shaped opening in the tripping-piece c and secured thoroin by
means of the bolts, screws, pins, koys or cottars d, or their equivalents.
tripping-piece c projects on either side of the slot a' and is free to turn or move
therein until it comes in contact at two points with the inclined sides of the said
Thus the flakes b can turn or pivot therewith in either direction to a suitable
inclination or angle relatively to tho shank a, and thereby enable the anchor to
bite or take the necessary hold upon the ground.
Blot.
The
The anchor as described may be used without a stock but if a stuck bo employed
it can be formed and fixed as shown in Figures 3 and 4. ; represents the stock
which is formed with a central hollow boss, of such size that it can be passed over
the extremity of the shank a before the shackle f is fixed theroon. An opening
is provided in the boss j and shank a through which a bolt or its equivalent is
passed and whereby the stock is retained in position.
It will be seen that my improved anchor is so constructed that the flukes & can
separately and very readily disconnected from the shank a, thereby greatly
facilitating the stowage thereof for storing or transport; also that a worn, broken
or damaged fluke can be readily removed independently of the other one and
a perfect one substituted.

page_text: Upon the anchor boing dropped in the usual manner it will fall with the shank a
upon the bottom and with one of the ends of the tripping-piece centering the
ground. Iminediately the cable attached to the shacklofbecomes taut through
the pull of the ship the tripping-piece c, and with it the flukes b, will become canted
in the manner clearly shown in Figure 2. Any further pull of the ship will simply
cause the flukes b, owing to their degree of inclination, to become further buried
in the ground and maintain a firm hold therein. A's, however, the cable is haulod
iu, the shank a will be raised, and the pull becoming more nearly vertical, the
ground above the flukes b will be easily broken up, and the latter will lose their
hold togother with the tripping-piece c.
By my invention I obtain considerable increase of strength in proportion to
weight of metal. The strain upon the flukes 6 is communicated direct to the
tripping-piece c owing to the square portions bx of the flukes fitting into the
correspondingly shaped openings in the tripping-piece. The tripping-piece in turn
beds at two points upon the inclined walls of the slot a', in whichevor direction the
flukes b may be canted.
Having now particularly described and ascertained the nature of my said inven-
tiou, and in what manner the same is to be performed, I declare that what I
claim is :--
1. An anchor comprising a shank a provided with a boss such as a* which boss
has an opening as a** and a slot a' with inclined walls, a double wedge-shaped
tripping piece such as c inserted in the slot al, and separate flukes such as beach
provided with a reduced portion 61 adapted to fit into and pivot freely in the
opening and each terminating in a square or like part adapted to fit into
the said tripping-piece and to be secured thereto by bolts d or their equivalents,
whereby the said flakes can turn or pivot with the said tripping-piece in either
direction to a suitable inclination relatively to the said shank and thereby enable
tho anchor to bite or take the necessary hold upon the ground.
2. The improved anchor constructed substantially as described and as illustrated
in the accompanying drawings.
