improvements in HOUS
1, JOHN EYNON, of No. 7 Kensington Terrace, Gateshead, in the County of
Durham, Foreman Forgeman, do hereby declare the nature of said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The improvements relate to the manufacture of anchors with special reference to
simplifying their construction of forged iron or steel and further to constructing
anchors of any of the existing types of tripping" anchors (with or without "stocks")
with auxiliary "trips" on the back of the "crown piece or of the "tripping"
arnis which operate when the anchor reaches the ground, to turn the "tripping"
arms, with the main arms and palms, into penetrating position.

On the accompanying sheet of drawings Figs. 1, 1, 2, 2, and 3 shew an anchor
made according to my invention in which the main arms with palms and the
tripping" arms are formed of one solid forging of iron or steel with a separate
fitting forming a "keep" of cast steel, and having upon it the auxiliary
when the anchor is so constructed.
trips,'
Fig. I is a longitudinal section of the anchor and Fig. 1^ an end view of the back
of the "crown piece" with the " keep" fitting, having upon it the auxiliary
trips" (shewn by dotted lines) removed.

Fig. 2 is a plan of the anchor, in section through the centre line of Fig. 1,
and Fig. 2 is a back view, with the auxiliary "trip" fitting in position.
Fig. 3 is a side elevation of the anchor with the main arms in holding position at
an angle of 45°. The "crown-piece," comprising the main arms A and palms B
with a centre block C and "tripping" arms D, form one solid forging, the centre
block C having cut out of it a cavity E so shaped that the eye of the shank F can
be put through from the front and a trunnion pin G inserted the ends of which,
when the shank is pulled forward, rest on the semicircular bearings H formed in
the cavity E. The casting J, on which are formed the auxiliary "trips" K, is
then inserted in the cavity E and secured therein by the bolts I, thus fixing in the
manner of a "keep" the shank eye and "trunnion" pin in the "crown-piece." The
tripping "arms Dare short projections upon, and of the full width of, the block C,
and form stops for the main arms and palms at the proper angle as shewn on Fig. 3,
the cavity E in the block being spread out, as shewn in Figs. 1 and 3, to the proper
extent to allow the main arms to turn to an angle of 45° on either side of the shank.
The cavity E will be cut out of the heated forging by the hammer and finished by
smithing with suitable shaped "fullers and the complete forging produced at
much less cost than by any existing method of making an anchor of forged iron
or steel.

K
Figs. 4, 5, and shew the application of the auxiliary "trips" K to an anchor
having the main arms A with palms B "tripping" arms D and auxiliary "trips
formed of one casting of steel and secured to the eye of the shank F by a "crown
bolt P.
In the case of existing anchors the auxiliary "trips" may be bolted to the back
of the "crown-piece "being cast of such shape as to suit, according to the form of
the latter.
•
Figs. 7, 8, 9, and 10 shew the action of the anchor at four stages, from first
touching the ground till the main arms have been fully "tripped," have penetrated
the ground, and are stopped at their proper angle by the "tripping" arms resting

page_text: upon the shank or by a quadrant stop in the eye of the shank, the anchor taken as
an illustration being that described in my Patent No. 5071 of 1893 as made of cast
steel. Fig. 7 shews the anchor having reached the ground and commencing to cant
over by the weight of the cable, one of the horns K K now holding and having so
far "tripped" the main arms. Fig. 8 shews the anchor further canted by the drag
of the cable one of the "tripping" arms D D having now entered the ground.
Fig. 9 shews the "tripping" arm embedded in the ground and bringing the main
arms into penetrating position, and in Fig. 10 they have fully penetrated and are
stopped at the angle by the point of the "tripping" arms resting on the shank.
Of course these stages follow each other instantaneously and the figs. are only to
illustrate how the "tripping" horns act as auxiliary "trips" at the first stage, and
afterwards assist the holding power of the anchor, giving an extra grip of the
ground. The auxiliary "trips," acting immediately the anchor reaches the ground,
require less cable " paid out which is an important advantage especially with
stockless anchors.
Having now particularly described and ascertained the nature of my sail
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The construction of anchors of forged iron or steel having the "crown-piece,"
comprising the main arms and palms, and the "tripping" arms, forming one solid
forging with an open cavity cut through the centre, so shaped that the eye of the
shank can be passed through from the front and a trunnion pin inserted, (or
alternatively the shackle end passed through the back) the cavity being so shaped
that the "crown-piece" will turn upon the trunnion pin to the required angle and
be there stopped by one of the "tripping" arms resting upon the neck of the shank,
the trunnion pin being secured in position in the cavity by a cast steel "keep" upon
which may be formed auxiliary "trips" substantially as described and in one form
shewn.
35
2nd. The application to anchors, having "tripping" arms, of auxiliary "trips"
upon the back of the anchor forming horns, or like projections, and acting when the
anchor reaches the ground to cause the "tripping" arms to take hold and so turn
the main arms and palms to the proper angle for penetrating and holding,
substantially as described and shewn in different forms of anchors.
