Improvements in Anchors.
I, JOHN VERITY of 14 Church Road, Stanley, Liverpool, in the County of
Lancaster, 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 :—
This invention has reference to that class of anchor generally termed "stockless"
anchors, and the shank of which generally, as used on board ship, passes through the
hawse pipe, while the flukes lie along the side of the ship; and the chief object of
my invention is to so construct anchors, that when the shank is pulled up the hawse
pipe, their flukes will always be brought up to and lie closely along the side of the
ship, so that the tips of the flukes do not project; while a further improvement
consists in the manner of holding the shank in the fluke head.
My invention will now be described with reference to the accompanying drawings,
in which Figure 1 is a back end view of the anchor; Figure 2 is a plan; and
Figure 3 a cross section of same at A A Figure 1.
Figure 4 is a general view of the anchor in position.
Figures 5 and 6 show details of the anchor.
Referring now to the drawings, a is the fluke head of the anchor, b are the flukes,
and c the shank. The flukes and fluke heads of the anchor are, as will be seen, cast
in one, the fluke head being extended out at either side into wings, forming the
usual trippers d of the anchor. The hawse pipe mouth is designated e, f being the
usual beading or flange round it.
With regard to the chief object of my Invention above referred to, namely, the
constructing of anchors so as to ensure their fluke points coming close up to the
side of the ship when the shank is pulled through the hawse pipe, it is found in
practice with anchors as at present constructed, that while in many cases this action
is satisfactorily obtained, yet in many cases it is not obtained; this being owing to
the fact, that in different ships, the measurements of the mouths of the hawse pipes,
and the pipes themselves, vary, which renders the uniformly correct and desired
action of the anchor, as applied to different ships, impossible. Now the object of iny -
invention is attained by providing upon the fluke head at each side of the centre line
of the anchor, inclined projections h, which in any case, no matter what size the
hawse pipe mouth may be, will, when the anchor is hauled into position, rest (that is
the lower inclined part will rest) upon the beading or projecting Hange f surrounding
the hawse pipe mouth; and in this action, when the lower inclined part / comes
against the hawse pipe flange f referred to, the pull upon the shank causes the tips
of the flukes to move inwards until they practically touch the ships side.
With regard to the means of holding the shank in the fluke head, and the con-
struction of head, the shank has trunnions i at its head, which in the case shewn in
the drawings are formed by the projecting ends of a pin, which is suitably secured in
the head of the shank; and these trunnions normally fit in seats, in the form of
recesses, provided in the bottom of the chamber of the fuke head, in which the
shank head and trunnions fit and work; while the shank itself passes through a hole
in the bottom of the chamber 1, of the full width of the shank head.

page_text: The trunnions of the shank are held in position, that is prevented from moving
out of the seat k, by the bars or blocks m, which in turn are held in position against
outward pressure exerted upon them by the trunnions i, by the corner pieces o, which
are provided at each corner of the chamber 1, and under which the ends of the blocks
or bars m come when placed in position. These blocks or bars m are placed in
position when the shank is in place, by passing them down through the space between
the ends of the chamber and the faces of the shank c; and then moving them
horizontally so that the ends of this bar or block m lies under the corner pieces o
whilst the vertical portion lies in between the pieces o at either side. Thus all strain
due to the backward pressure of the shank head is finally transmitted to, and borne
by the fluke head. When the blocks or bars m are placed in position, they are
prevented from coming out of place, that is from moving laterally, by rivets or bolts
and nuts p, which are passed through them, and through the side or end of the fluke
head. Practically no strain comes upon these bolts.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. A stockless anchor having upon its fluke head a projection or projections (h) on
either side of the centre of the shank, adapted to rest, when in the housed position,
upon the projecting edge at the side of the hawse pipe; substantially as and for the
purposes described.
2. In a stockless anchor, the construction substantially as described by which the
shank is held in position in the fluke head.
3. The stockless anchor having parts arranged, constructed, and adapted to operate,
particularly as set forth with reference to and shewn in the drawings.
