PROVISIONAL SPECIFICATION.
Improvements in Ships' Anchors.
I, WILLIAM ROSE of The Mount, Halesowen, in the County of Worcester,
Gentleman, do hereby declare the nature of this invention to be as follows:-
Usually, the cross head commonly called the body, and also the arms, of two
armed self-canting anchors, are made solid, or in one piece, and usually by the
process of casting; and further, the limiting stops of the shank are made by additions
on the body part.
By my invention, the said body part and armis, are made separate, and preferably
of wrought metal:
Thus, my invention consists essentially in making the said cross-head, arms, and
shank respectively, and threading them upon a central axis, with supplementary
cross stay or stays, and connecting links, for making the head and toggle arms move
together, as if they were made in one single piece..
In carrying out my invention as applied to a double armed self-canting, ships'
anchor, I proceed as follows:-
I make the toggled arms T shaped, of which the head constitutes the toggles,. and
directed transversely through the middle of the body part of the toggle and arm,
a hole is made, wherethrough the axis or shaft as herein-after described, passes, in
connecting the toggled arms to the head end of the anchor.
The arms which form a part of the cross head, are disposed on the two opposite
sides of the head of the shank or stock, and wherethrough the common axis or shaft
as aforesaid passes:
Disposed between the two opposite sides of the inner end of the shank, and the
checks of the inner arms, are distance sleeves, or hollow cross heads, with strap
connections on their inner sides, and between which, the inner end of the shank
comes and works. These straps or brackets constitute in themselves, couplings from
the main axis to the toggled arms, in such a manner, that stay pins directed parallel
to the main axis, and through the straps and toggles of arms, connect and rigidly
affix the same together'; so that the whole of the parts forming the anchor, other
than the shank, move and operate together as if they were made in one solid
piece.
Thus, in one form of my invention, the connecting straps or brackets are made
doubled armed, and with their middles threaded upon the main axis, and their ends
threaded and taking, upon parallel and transversely directed stay pins, which pass
through, and are directed from the opposite sides of the arms, or from the toggles
thereof; so that the said arms, body part, toggles, stay pins, distance sleeves, loops
or brackets, (the whole constituting the head end of the anchor,) move together, whilst
the shank which is jointed upon the middle of the main axis, admits of turning freely
upon it.
In putting together the component parts of the said anchor, one toggled arm is
first threaded upon the stay pins and axis, and brought up to the threaded outer
ends, then' comes a distance sleeve, which is threaded only upon the axis, which has
next upon it, coupling straps or brackets, with the inner end of the shank jointedly
connected between them, which is followed by another distance sleeve, and the other
toggled arm, thus completing the head end of the anchor, which is stayed and fixedly
connected together by riveting the inner ends of the stay pins and axis, or by passing
a screw nut upon the screwed ends of the said pins and axis, which lie parallel to each
other, and in the same, or in different planes.
The transversely directed stay pins, which couple and thread the component parts
of the anchor head end together, constitute stops, for limiting the movement

page_text: :
of the shank, and against which its inner end comes or abuts, when the anchor
is used.
In another form of my invention, I thread a central axis or shaft through the
body part of the arms, and through distance sleeves, with straps or bracket links
hetween them, and between the straps, the inner end of the shank comes and
works.
A single stay pin or rod, which is disposed rearwardly of the main axis, couples the
arms, straps and other parts together.
Thus, the stay bar runs parallel to the main axis, with its ends taking into the
toggles, or extensions of the arms, beyond the joint pin; so that the central axis,
arms, toggle, and cross head move rigidly together upon the end of the shank as a
bearing, which may be gapped like into a forked end, which forms stops, against which,
the rearwardly directed stay-bar, comes.
In another form of my invention, straps may be carried by, or formed in one piece
with the straps or brackets, instead of being made separate.
Instead of employing two links or brackets made separately, and threaded upon the
the central axis, and pin or pins, I employ a double bracket, joined together by fixed
or loose connections, and with the inner end of the shank coming between the cheeks
of the bracket.
By making or building up anchors in segments or parts, and, connecting them
together by excentrically directed stay or coupling rod or rods, which takes or take
through extensions of the arm or plug part, and links or brackets respectively, a
great saving in the cost of manufacture is attained; and further, anchors so
produced, are vastly superior in resisting strain over those of the ordinary con-
struction.
Although I have described that the parts or segments are preferably made of
wrought iron or steel, yet the same may be made of cast metal.
The links or brackets may be made in one piece with the distance sleeves,
so that they form as it were, cranks, which are the couplings of the parts as
aforesaid.
The brackets or straps instead of being loose, may be keyed upon the main shaft,
and when so arranged, the inner end of the shank has lugs or projections made upon
its inner end, which come against the said fixed bracket or brackets, and form
stops. By so constructing anchors, the distance sleeves and stay pins are dispensed
with..
I wish it to be understood, that my invention is applicable to all forms of anchors,
which cant and turn upon the inner end of a shank.
The primary axis or shaft may be round, square, or of any other cross section.

COMPLETE SPECIFICATION.
Improvements in Ships' Anchors.
I, WILLIAM ROSE, of the Mount, Halesowen, in the County of Worcester, 4
Gentleman 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 :-
Usually the cross-head, commonly called the body, and also the arms, of two
armed self-canting anchors, are made. solid, or in one piece, by the process of
casting.
According to my invention, I build up the anchor of component parts, and
connect them together, by means of a square or round shaft or axis, as hereinafter
described.
· Figure 1 of the accompanying drawings, represents in elevation, a two armed

page_text: self-canting and stockless ship's anchor, constructed according to one form of my
said invention. It will be seen that the head or inner end of the shank, which is
enlarged, works within the interior of a frame, and upon a threaded bush, disposed
around the middle of a common shaft or axis, upon which, the whole of the component
parts constituting the cross head, arms with flukes and the like, are separately
threaded, as herein-after described.
The frame as aforesaid, constitutes both the toggle for tripping the arms or flukes,
and also limiting stops for the shank. The whole of the component parts constituting
the grappling end of the anchor, move together, as if they were made in one
solid piece, in consequence of the said parts having angular eyes or holes made
through them, which take upon a plain shaft, of a corresponding section to the said
eyes or holes.
Figure 2 represents a side elevation of the said anchor, with the inner end of the
shank, resting upon one of the stops of the toggle frame.
Figure 3 represents a transverse vertical section, on the dotted lines B figure 1,
showing the bush upon which the shank turns, and also the stops of the toggle frame,
which embraces the said head end of the shank.
Figure 4 represents a back end elevation of the said anchor figure 1, whilst figure 5
represents a transverse horizontal section on the dotted lines CD figure 4, thus
exemplifying how the threaded and component parts constituting the grappling end
of the anchor, are threaded in common upon one angular shaft or axis, plain or
uniform in diameter from end to end, other than in respect to the riveting and
worming at the ends.
Figures 6, 7, 8, 9, 10, 11, 12 and 13 represent elevations, part sections, and plans
of the component parts of the said anchor."
a is the shank of the anchor, with head a at its inner end, pierced with a joint
hole a³, which takes upon the circular outside face of a square bush b, 62, whose
assigned position is the middle part of the plain square shaft or axis c.
This shaft
or axis, is directed transversely from end to end of the component parts of the
grappling end of an anchor, and is adapted to connect and compel the said parts to
move together, (other than the shank) as if they were made in one solid piece. This
stem or axis, has an expanded head at one end, and is wormed at the other, upon
which latter, the nut d, takes. In figure 18, this shaft or axis is shown in
elevation and transverse section, with the wormed end marked c², and the rivetted
end .
The inner or head end of the shank, works within a frame e, with top and bottom
ends e, constituting toggles, whereby the anchor head end parts, are tripped.
This frame, has an angular or square hole e³, made transversely through it, and a
rear and back hole e', for the threading through it, of the shank, or the head end
of it.
Disposed on the two opposite sides of the said frame, and upon the square axis or
shaft, are distance sleeves f, with square or angular holes f, of the cross section of
the spindle or shaft c, made through them.
Directed at the two outer ends of these distances sleeves, and upon the square axis
or shaft, are arms g, with flukes g², at their fore parts. The inner ends of the arms,.
are provided with square holes g³, of the cross section of the shaft, upon which they
are adapted to be threaded or pass, and are prevented from rotating, other than in
common with the whole of the other parts and shaft, leaving the shank to turn upon
its bush.
It will be thus seen that the component parts of the anchor, are made separate,
and connected together, by threading them upon a common axis or shaft, which
both connets them together, and makes them turn in common one with another, in
respect of all parts other than the shank.
In putting the said intrigal parts together, first thread one of the combined arm
and flukes g, g², g³, up to the shoulder c3 of the axis or shaft c, then thread one of
the distance sleeves f, f, up to the inside presented face of the arm, this done, then

page_text: place the bush b, within the hole or eye a³, through the head of the sbank, then pass
the said head and bush together into the middle of the opening e, of the frame e,
and with a square hole 2 of the said bush, coincident with the square holes e³, of
the frame e, then pass the screwed end of the axis or shaft c, through the holes
and e, of the said parts. This done, thread the second distance sleeve and arm upon
the said shaft, followed by the screw nut, which is screwed upon the worm end c²,
thereby bringing the whole of the parts other than the shank, in close proximity to
each other.
Instead of employing a rivetted head on one end of the shaft, and a nut on the
other, I may employ two rivetted heads, one formed after the threading of the parts
has been completed, or nuts, screwed at both ends, may be employed.
Instead of nuts or rivettings, the outer ends of the shafts, may be extended, and
lynch-pins or cotters, passed therethrough.
Figure 15 represents another form of my invention. In this arrangement, the
dxis or shaft is circular, and the component parts constituting the grappling end,
connected together, and prevented from rotating, by an excentrically arranged cross
rod, taking through bracket plates of the one part, and toggle extensions of the arms,
of the other part or parts. This transversely directed cross rod, which constitutes a
stay, forms between the bracket plates, a limiting stop, for determining the angular
movement to be made by the shank.
Figure 16 represents a transverse section on the dotted lines E F figure 15,
exhibiting the shape of the gapped outside end of the head of the shank, and also
the shape of the bracket plates, and further, it also shows the toggles on the rear
extensions of the arms.
Figure 17 shows a back elevation of figure 15, and figure 18 represents a trans-
verse horizontal section of the grappling end of the said anchor, thus exhibiting how
the component parts constituting the said end are threaded upon a plain shaft or
axis, and are prevented from rotating or turning (other than the shank) by a
transversely directed and threaded rod, parallel, and at a distance from the main
shaft.
a is the shank, with head a², turning upon a plain round shaft c, directed in
'common through circular holes e³ of bracket plates e, disposed on the two opposite
sides of the said head of the shank, and through circular holes g³, of arms or flukes
and also through circular holes 2, of distance sleeves f, disposed between the bracket
plates, and arms or flukes.
The head of the shank, turns upon the naked middle part of the shaft, whilst the
other component parts are kept within respective positions, and up to the shoulder of
the rivetted heads, by a screw nut d, taking upon a wormed end c².
The component parts (other than the shank) are prevented from turning, by an
excentric, and transversely directed rod or stay h, having a rivetted head, at one
end, and passing through holes g^, et, respectively, of arms g (or rear extensions of
them) and bracket plates e, respectively.
The rod is secured at the other end by a nut h³.
The rear of the head of the shank is made with a recess a³ with shoulder at, at the
extremities of it, and within the path of the said recess, the middle part of the rod h,.
comes, and constitutes a stop, for limiting the movement of the shank, with respect
to the grappling end or arms part.
The component parts as aforesaid, are first threaded upon the shaft in the order as
represented, and then the rod h, is threaded through the said parts as shown.
Figure 19 shows a like type of anchor figure 15, but with a differently constructed
frame, viz., this frame is alike unto that represented in figure 1, but having the rod
passing through ears of it common with the arms.
a is the shank, a² the head thereof, e the frame, e² the stops of the shank, e³ the
"ear extensions of the frame, the stay rod, for making the frame and arms g, move
together.
The rear extensions of the arms, are formed into toggles.
