We JOHN FRANCIS HALL of Norbury, Sheffield, in the County of York, Manager
of Steel Works, and JOHN VERITY of Billing Bank, Bramley, near Leeds in the
County of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
The objects of our invention are to simplify the construction of anchors and to render
them more efficient and certain in their action, and less liable to roll over than here-
tofore; a common fault with some anchors, causing the cable to twist and break.
According to our invention we make the arms or flukes in one piece, and at the
crown or upper portion thereof a trough is provided for the reception of the trunnions,
which are formed on the upper end of the shank and fit between two projecting parts
within the trough. A bolt or pin being passed through the projecting pieces and
trunnions, retains the shank in position between the arms or flukes, at the same time
allowing a radial movement of the arm to any required angle.
The trunnions after being placed in position in the trough and secured there by
means of the aforesaid bolt, are enclosed therein by a suitable cover.
In order to place the shank in position, a hole is provided at the bottom of tho
trough through which the shank is passed where it is held by the hereinbefore
mentioned bolt.
In order to make the action of the anchor more certain we provide projecting or
"tripping up" pieces on the crown or upper portion of the trough, these arms having
the effect of throwing over the arms of the anchor into position for instantly taking
hold of the ground as the anchor is dragged thereon.
The stock bar is formed in two parts these are hinged onto the shank in a suitable
position, so that they can be turned down against the sides of the shank in order that
such stock bar when closed against the aforesaid sides can be drawn up therewith into
the hawse pipe, or compactly stowed on deck or at the side of the ship.
This arrangement of hinged stock bar is applicable to other anchors.

top. Figs. 4. 5. 6. 7. 8. 9. 10 and 11 are various views shewing details of the same.
According to our invention we make the two arms or flukes A in one piece, pre-
ferably in cast steel, and at the crown or upper portion thereof is formed a trough B
for the reception of the trunnions C which are formed on the upper end of the shank D
and which fit between two projecting parts E formed across the bottom of the
trongh B.
A bolt F or pin being passed through the projecting parts E and trunnions C retain
the shank D in position between the arms or flukes A, at the same time allowing of a
radial movement of the arms or flukes A to any required angle.
In order to place the shank D in position a hole G is provided through the bottom
of the trough B through which the shank D is passed and afterwards held in position
as shewn in drawings by the hereinbefore mentioned bolt or pin F.
"
The outer edges of the walls H of the trough B perform the duties of "trippers
but in order to more completely perform this operation we form or provide on their
edges the projecting pieces J; by this arrangement the flukes or arins A of the anchor
are instantly thrown into position for taking hold of the ground immediately the
anchor commences to drag thereon.
We apply what is known as a fisher at K for hooking up the anchor when
required.
This anchor being without a crossbar can readily be drawn into the hawse pipe and
easily stowed.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
:-
1st. The arrangement of arms or flukes A constructed in one piece, substantially as
herein set forth.

page_text: 2nd. The arrangement and application of the walls H forming the trough B for the
trunnions C of the shank D and the means employed for securing the same together,
substantially as herein set forth.
3rd. The application of the walls H of the trough B, and the projecting pieces J
for the purpose of "tripping" or throwing over the anchor into position, substantially
as herein set forth.
4th. The combination of the various parts forming the anchor, substantially as and
for purposes herein set forth.
