Improvements in Anchors.
I, FREDERICK CHARLES CHURCH, of 14, Bourne Street, Dudley, in the County
of Worcester, Commercial Clerk, do hereby declare the nature of my said inven-
tion to be as follows:-
My invention has for its object improvements in anchors the shank of which
is free to move upon its bearings in the head and is simple in construction,
the shank being held in the head in such a manner as to prevent any foreign
substance from entering the bearings.
In carrying my invention into practice I form the end of the shank which
fits into the head of the anchor and which is held in position by a pivot pin
with curved or rounded sides and with a curved or partially rounded base which
forms the bearing surface of the shank. The head of the anchor to which the
arms are attached is formed with a central socket into which the end of the
shank fits and the base of this socket is formed with a projecting part or bearing
upon which the bearing portion of the shank fits or works. This bearing portion
is formed separate when the head is made from wrought iron or steel and fits
into a slot or recess on the underside of the head and is held therein by bolts
or rivets but when the head is made from cast steel the bearing portion may
be made in one with the head. The pivot pin which holds the shank in position
fits into bearings formed in the head and this pin is held in its bearings by two
bearing caps bolted or rivetted to the head thus preventing any foreign substance
from entering the bearings.

I, FREDERICK CHARLES CHURCH, of 14, Bourne Street, Dudley, in the County
of Worcester, Commercial Clerk, do hereby declare the nature of my said inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
My invention has for its object improvements in anchors the shank of which

page_text: is free to move upon its bearings in the head and is simple in construction,
the shank being held in the head in such a manner as to prevent any foreign
substance from entering the bearings.
In carrying my invention into practice I form the end of the shank which
fits into the head of the anchor and which is held in position by a pivot pin
with curved or rounded sides and with a curved or partially rounded base which
forms the bearing surface of the shank. The head of the anchor to which the
arms are attached is formed with a central socket into which the end of the
shank fits and the base of this socket is formed with a projecting part or bearing
upon which the bearing portion of the shank fits or works. This bearing portion
is formed separate when the head is made from wrought iron or steel and fits
into a slot or recess on the underside of the head and is held therein by bolts
or rivets but when the head is made from cast steel the bearing portion may
be made in one with the head. The pivot pin which holds the shank in position
fits into bearings formed in the head and this pin is held in its bearings by two
bearing caps bolted or riveted to the head thus preventing any foreign substance
from entering the bearings.
In order that my invention may be more clearly understood and easily carried
into practical effect I have appended hereunto two double sized sheets of drawings
upon which I have illustrated examples of my anchor.
Figure 1 is a perspective view of my anchor complete.
Figure 2 is a front elevation of my anchor.
Figure 3 is a side elevation of Figure 2.
Figure 4 is a part sectional plan view of Figure 2.
Figure 5 is an enlarged part sectional side elevation shewing the shank in an
upright position.
Figure 6 is a similar view to Figure 5 shewing the shank in an inclined
position.
Figure 7 is a similar view to Figure 5 with the shank and its bearing portion
removed.
Figure 8 is a detached view of a portion of the shank.
Figure 9 is a view of the detachable portion which forms the bearing of the
end of the shank.
In carrying my invention into practice I form the end a¹ of the shank A which
fits into the head B of the anchor and which is held in position by the pivot
pin with the curved or rounded sides and a and the curved or partially
rounded base a which base forms the bearing surface of the shank. The head B
of the anchor to which the arms or flukes D are attached is formed with the
central semi-circular-socket 62 sufficiently large for the end a' of the shank to
fit into. The base of this socket is made with the projection or bearing part el
which forms the bearing for the end a¹ of the shank A. When the head B of
the anchor is made from wrought iron or steel this bearing part e¹ is formed
on the separate bearing piece E which fits into the recess 63 formed in the under-
side of the head as clearly shewn at Figures 1, 5 and and this separate bearing
piece E is held in position in the head by the bolts and nuts e² which pass
through holes formed in the bearing piece and in the head B as shewn at
Figures 1, 2, 3 and 4. Or the bearing piece E may be rivetted or otherwise
secured to the head. Or when the head B and flukes D are made from cast metal
the bearing part or surface e¹ may be made in one with head. It will be seen
that the sides e of the bearing part el are formed at an angle and that the
parts at the end of the shank A are also formed at an angle sloping down-
wards from the bearing part or base a to the circumference of the end a¹ so
as to limit the extent of the oscillating movement of the shank A as clearly
shewn at Figures 5, 6 and 8. The ends of the pivot pin 61 upon which the shank
works fit into the bearings 6 formed in the head B and this pin is held in its
bearings by the bearing caps 65 and 66 bolted to the head by the nuts and
bolts as clearly shewn at Figure 4.

page_text: Having now particularly, described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
CLAIMS.
First: The improvements in anchors consisting essentially in forming the
end of the shank with bearing surfaces such as with the rounded sides and
with or without a bearing at el formed in the head the said shank being held
in position by a pivot pin in bearings in the manner and for the purpose sub-
stantially as herein set forth and as shewn upon the accompanying sheets of
drawings.
Second In anchors, pivotally mounting the end of the shank in a socket
or recessed part formed in the head the said shank taking its bearings upon a
fixed or removable bearing piece such as E with its angular sides forming stops
for limiting the oscillatory movement of the shank the shank being so formed
as to practically seal up the recess in the head in the manner and for the purpose
substantially as herein set forth and as shewn upon the accompanying sheets
of drawings.
Third: In anchors such as claimed in the foregoing claims the stop E fast or
removable formed or fixed at the bottom of a recess in the anchor head.
Dated this on way of buy 1000
