State of Massachusetts.
My Invention relates to that class of anchors wherein the stock has its fluked arm
or arms pivoted to it, my Invention being an improvement or improvements thereon,
and consists: First, in an anchor composed of a single fluked and barbed arm, a
furcated shank and transverse stop pins, and a pivotal bolt; second, in an anchor
composed of a single fluked and barbed arm, a furcated shank and transverse stop
pins, and a pivotal bolt and a clevis; third, in an anchor composed of a single
Huked and barbed arm, a furcated shank and transverse stop pins, and a pivotal
bolt, and having between the extensions of its shank prongs below the fluked and
barbed arm an open space; the whole being made of metal.

HENRIETTA SEWELL FOWLE, of the State of Massachusetts, of the United States
of America. "A NEW AND USEFUL IMPROVEMENT IN ANCHORS FOR NAVIGABLE
VESSELS." A communication from Seth Whittier and Albert Rufus Whittier, of the
State of Massachusetts.
My Invention relates to that class of anchors wherein the stock has its fluked
arm or arms pivoted to it, my Invention being an improvement or improvements
thereon, and consisting,-
First. In an anchor composed of a single fluked and barbed arm, a furcated shank
and transverse stop pins, and a pivotal bolt, arranged and applied substantially in
manner as hereinafter set forth.
Second. In an anchor composed of a single fluked and barbed arm, a furcated
shank and transverse stop pins, and a pivotal bolt and a clevis arranged and applied
substantially as hereinafter set forth.
Third. In an anchor composed of a single fluked and barbed arm, a furcated
shank, and transverse stop pins and a pivotal bolt, and having between the exten-
sions of its shank prongs below the fluked and barbed arm an open space, as set
forth.
The said Invention is shown in the accompanying Drawings, of which,—
Figure 1 is a front view.
Figure 2, a side elevation; and
Figures 3 and 4, longitudinal sections thereof, or of an anchor ombodying it.
Figure 5 is a side view of the barbed and fluked arm; and Figure 6 is a front
view of the furcated shank.
In such Drawings, A. denotes the shank provided with two prongs a, a, and a
space or opening 6 between them, and extending between them from their lower
ends up to their intersections with the part c above them, such part being provided
with a ring B and a stock C.
The pivoted arm is shown at D, as arranged between the prongs of the shank,
and connected to them by a pivot or bolt d that extends through them near the
lower ends of the prongs, the space e between the extensions of the prongs below
the lower end of the arm being entirely open, so that no mud or extraneous matter
may gather therein to prevent the arm from turning on the bolt. The said arm has
a single fluke f and two barbs g, g, arranged with it in manner as represented; and,
furthermore, there are two stop pins h, h, inserted and fixed in the prongs and with
reference to the arm in manner as represented. Each of the said pins serves as a
stop to arrest the arm in its greatest angular position with respect to the shank,
when said arm may be projecting either way from the shank.
A yoke or clevis i spans the prongs at their lower parts and turns on the bolt d.
By means of this clevis a rope or chain may be connected with the toe of the anchor
for supporting the anchor or aiding in moving it or taking it in board.
When the arm is wholly or about so between the prongs, the barb that may bo
projecting downward will catch in the ground, as the anchor may be drawn along,
and will serve to turn the arm down, so as to cause its fluko to enter the ground.
In the anchor, as represented, the stock is of the kind that can bo slid lengthwise
through the shank, and be turned down into or about into parallelism therewith.
The arm may also be turned wholly between the prongs of the shank, the anchor in
this way being capable of being folded in a small compass for storage.
I claim as my Invention as follows,-
First. The improved anchor, composed of the single fluked and barbed arm, the
furcated shank, and the transverse stop pins and pivotal bolt, arranged and applied
substantially in manner as set forth.

page_text: Second. The improved anchor, composed of the single fluked and barbed arm, the
furcated shank, the transverse stop pins, and a pivotal bolt, and a yoke or clevis,
arranged and applied substantially as set forth.
Third. The improved anchor, composed of a single fluked and barbed arm, as
shown, a furcated shank and transverse stop pins, and a pivotal bolt, and having
between the extensions of its shank prongs, below the fluked and barbed arm, an
open space as set forth, all being arranged and applied as described and represented.
In witness whereof, I, the said Henrietta Sewell Fowle, have hereunto set my
hand and seal, this Third day of July, A.D. 1879.
