An Improved Ship's Anchor.
I, CORNELIS BONGER of Leiden, in the Kingdom of Holland, Managing Director
of tn Koninklyke Nederlandsche Grofomederz, 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 a stockless ship's anchor and has special reference to
certain improvements on the invention described in Specification No. 5379 of 1893,
for which Letters Patent have been granted to me.
The invention set forth in the said specification consisted mainly in providing a
shank and fluke or head, constructed and mounted so that the fluke body can caly
move a certain angle or distance, and further in the provision on the fluke body of
auxiliary flukes behind the main flukes for the purpose of giving better holding
capacity to the anchor, and for the prevention of its overturning when lowered to
the ground.
The object of the present invention is to provide an improved form and arrange-
ment of these said auxiliary flukes for the purpose of improving the position of the
anchors when suspended from the hawse pipes and against the bow sides of the
ship, and by means of which the anchor can be more easily taken charge of and
stowed away in the stowing places and against the ship-board. This object is
attained by placing the auxiliary flukes lower down with regard to their position
on the arms of the main flukes. A further improvement is effected by making the
bottom of these auxiliary flukes flat instead of curved as heretofore, the object of
which is to increase the holding power and resisting capacity of the anchor, and
to prevent a turning over at the bottom of the sea when falling out of the hawse
hole.
In order that this invention may be readily understood, reference is made to the
accompanying drawings, in which Fig. 1 is a front elevation of the said anchor,
partly in section, Fig. 2 an end or side view, and Fig. 3 a plan of the same, also
partly in section.
In these drawings, a is the shank or stem of the anchor, the fluke body turn-
ing right or left on the pin or shaft c, d d are the auxiliary flukes, ee are the
extended portion of said auxiliary flukes, hereinbefore described, each having the
base or bottom flange therefor of a flat shape as shown at f f.
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:-
1. An anchor having a movable fluke body revolving on a pin or shaft con-
nected with and at the end of the main shank or stem of the anchor, said fluke
body being provided with auxiliary flukes having prolonged bases and flat flange
ends, substantially as and for the purpose herein set forth and described and
illustrated by the accompanying drawings.

as and for the purpose herein set forth and described and illustrated by the accu-
panying drawings.
