Improvements in Anchors.
I, GEORGE FREDERICK SIMMS of the firm of G. Hartshorne & Co. of Primrose
Bridge Works Netherton near Dudley in the County of Worcester Manufacturer do
hereby declare the nature of my said invention to be as follows :-
The object of my invention is improvements in anchors and the improvements have
special reference to that class of anchors known as "stockless" and by which
increased holding powers are obtained together with greater steadiness in action.
The chief defects in stockless anchors hitherto are their liability to come out of the
ground or what is known as "roll" when in use and such anchors are also deficient
in holding power. Now my improvements are for the purpose of increasing the
holding power and ensuring steadiness in action. This I effect in the following
manner :-
1 form or mount upon each face of the anchor head either on the arins or cross
head two or more supplemental or auxiliary flukes in such a position that they will
hold the ground at the same time as the main flukes and thus by their supplemental
hold upon the ground prevent the anchor from rolling. The principal arms branch
off from the ends of the crosshead and take an inward direction terminating in the
main flukes nearer the shank thus giving more central resistance.
A tripping head when necessary may be made by forming projections on the upper
and lower faces of the crosshead as is the present mode adopted in the case of many
well known "stockless" anchors. The shank may be pivotted to the crosshead and
stops provided for limiting the angle which the flukes are allowed to take by any of
the well known ordinary methods. These anchors may be made from cast steel
wrought iron or other suitable metal and either cast or forged or the parts fitted
together or partly one & partly the other modes, and we may in some cases apply &
stock to our anchors though generally they would be without.

Improvements in Anchors.
1, GEORGE FREDERICK SIMMS, of the Firm of G. Hartshorne & Co. of Primrose
Bridge Works Netherton near Dudley in the County of Worcester do hereby declare
the nature of my said invention & in what manner the same is to be performed
to be particularly described & ascertained in & by the following statement, that
is to say:
The object of my invention is improvements in anchors: and the improvements
have special reference to that class of anchors known as "stockless" and by which
increased holding powers are obtained together with greater steadiness in action.
The chief defects in stockless anchors hitherto are, their great liability to come out
of the ground or what is known as "roll" when in use and such anchors are also
deficient in holding power. Now my improvements are for the purpose of
increasing the holding power and ensuring steadiness in action. This I effect in the
following manner :-
I form or mount each face of the anchor head either on the arms or crosshead two
or more supplimental or auxiliary flukes in such a position that they will hold the
ground at the same time as the main flukes and thus by their supplimental hold
[Price 6d1

page_text: upon the ground prevent the anchor from rolling. The principal arms branch off
from the ends of the crosshead and take an inward direction terminating in the
inain flukes nearer the shank thus giving more central resistance.
A tripping head when necessary may be made by forming projections on the upper
& lower faces of the crosshead as is the present mode adopted in the cases of many
well known stockless anchors. The shank may be pivotted to the crosshead and stops
provided for limiting the angle which the flukes are allowed to take by any of the
well known ordinary methods. These anchors may be made from cast steel, wrought
iron, or other suitable metal, and either cast or forged, or the parts fitted together
or partly one or partly the other modes, & we may in some cases apply a stock to
our anchors though generally they will be without.
In order that my invention may be clearly understood I have appended hereunto
a double sized sheet of drawings upon which I have illustrated one example of my
anchors which will be sufficient to enable others to apply the principle to other cases
as they occur in practice.
Figure 1, is a front view of one of my anchors consisting of two main arms and
their flukes, & four supplimental short arms and flukes, that is to say, two on each
side, or six flukes in all.
Figure 2, is an end elevation of the same anchor with the shank shewn in line
with the main arms and flukes as it would be when hanging from a ship before
reaching the ground.
Figure 3, is a view of the underside, of the anchor, tripping head, and crosshead,
& the back end of the two main arms.
Figure 4, is a sectional elevation on the line M. N. Figure 3, which shews the
shoulders & shank pivot more plainly.
Figure 5, is an illustration of the anchor after it has been lowered in work showing
the bite of the main arms & flukes & the supplimental ones also.
The main shank E of my anchor may finish with a shackle as shewn and I may
add a stock when necessary. The shank is pivotted to the head as shewn at Fig. 4.
so that when it is in action as there shown it is limitted by the shoulder R bearing
against the corresponding shoulder k¹ similar to the anchors we have made previous
to this patent; or the stop or shoulder may be formed in any known way or any
mode used to limit the angle of the arms. The main arms A finish with their
flukes a', as shown upon the drawings, tending inwards to the shank E. At or near
the end of the crosshead CI form two or more supplimental arms or flukes B on each
side thereof, so that they assist the main arms A when in action and tend to steady
the working of the anchor. The tripping head K may in some cases project beyond
the supplimental arms B× in case I use two or more supplimental arms on each side
or say three each side, or six supplimental arms. I may, if necessary, carry the two
outer ones even on to the end of the arms A placing the third equal distance between
them. It will be evident that I may, in using only two supplimental arms on each
side, carry them nearer together or even so far apart as to be on the root of the
main arms A.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what 1
claim is :-
The improvements in anchors having four or more supplimental arms or flukes ;
substantially as herein set forth and as shewn upon the drawings.
