PROVISIONAL SPECIFICATION.
Improvements in Anchors.
I, FREDERIC UDNEY BAXTER of Sandiacre near Nottingham in the County
of Derby Engineer and BAXTERS LIMITED of the same place Engineers do hereby
declare the nature of this invention to be as follows:-
The invention relates to improvements in anchors of that class which are known
as trunnion anchors and the object of the invention is to render such anchors more
certain in their action than heretofore..
In practice it is found with anchors of this class that the flukes or arms do not
enter the ground as quickly as is desirable, but have a tendency to lie upon the
surface and sometimes for the arms to remain above a horizontal position and in
order to obviate this defect it has been proposed to form upon the head fingers_
or projections the office of which was to catch the ground and turn the flukes
to the desired angle to cause them to enter, but these fingers were formed at
an acute angle with the flukes and therefore at times did not have the desired
effect.
Now the object of the present invention is to obviate this defect and for this
purpose in addition to the fingers hereinbefore referred to the head of the anchor
is provided upon each side thereof with two additional projections or fingers
arranged at or approximately at right anglos to the others so as to catch the ground
when the flukes are in a horizontal position and to prevent the arms taking any other
position when the anchor touches the ground than the most desirable one for them
to enter the ground directly a strain is brought upon the cable and thus the
efficiency of the anchor for practical purposes will be much improved and tho
anchor will be the more easily handled for stowing purposes on board ship.

COMPLETE SPECIFICATION.
Improvements in Anchors.
I, FREDERIC UDNEY BAXTER of Sandiacre, near Nottingham in the County of
Derby, Engineer, and BAXTERS LIMITED of the same place, Engineers, 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:—
The invention relates to improvements in anchors of that class which are known
as trunnion anchors and the object of the invention is to render such anchors more
certain in their action than heretofore.
In practice it is found with anchors of this class, that the flukes or arms do not
enter the ground as quickly as is desirable, but have a tendency to lie upon the
surface and sometimes for the arms to remain above a horizontal position, and in
order to obviate this defect an anchor of this class, and which is known as the
"Baxter" anchor is provided at the junction of the two flukes or arms with a head
formed with fingers or projections and which is termed the "tripping head," and
the office of these fingers or projections is to catch the ground, and turn the
flukes to the desired angle to cause them to enter, but the fingers or projections are
formed at an acute angle with the flukes, and therofore at times do not have the.
desired effect.

page_text: Now the object of the present invention is to obviate this defect, and for this
purpose in addition to the fingers or projections hereinbefore referred to, the head
of the anchor is provided upon each side thereof with two additional projections or
fingers arranged at or approximately at right angles to the others, so as to catch
the ground when the flukes or arms are above a horizontal position and to force the
flukes or arms into the most desirable position for them to enter the ground directly
a strain is brought upon the cable, and thus the efficiency of the anchor for
practical purposes will be much improved, and the anchor will be the more easily
housed for shipwork.
And in order that the said invention may be more clearly understood and readily
carried into effect, we will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of a trunnion anchor of the "Baxter " type,
embodying our improvements, and
Figure 2 is a front elevation thereof.
In both the figures of the drawings like parts are indicated by similar letters of
reference.
a represents the shank of the anchor, and b represents the arms or
flukes thereof,
which are constructed and attached to the shank a in the manner now well known,
and which it is unnecessary to specifically describe here.
represents the "tripping head" of the anchor, which is formed with fingers or
projections b, the office of which is to catch the ground and turn the flukes or
arms to the desired angle to enter as is well understood, and as hereinbefore
explained.
Now according to the present invention, in addition to the fingers or pro-
jections, the head of the anchor is provided upon each side thereof, with two
additional projections or fingers 6*2, arranged at or approximately at right angles
to the fingers or projections *1, so that they may first catch the ground when the
Hukes or arms are lying in such a position as to prevent either of the projections or
fingers from taking the ground, thus forcing the flukes or arms b to the
required angle to enable the fingers or projections 6* in their turn to catch
the ground and thereby force the flukes or arms to take the ground in the
required manner.
It may sometimes be advantageous to employ another set of additional fingers **
in order to render more complete the action hereinbefore described.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a trúnnion anchor the combination of the arms or flukes, the head, and two
sets of fingers such as 6*16* arranged on opposite sides of the head *, sub-
stantially as herein shown and described and for the purpose.stated.
2. In a trunnion anchor, the employment of additional fingers such as 6,
substantially as herein shown and described and for the purpose stated.
