page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of the Patent Office, Lincoln's Inn, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifteenth day of September, in the seventh year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Moses Poole, His especial license, full power, sole privilege and authority, that I,
the said Moses Poole, my exors, adññors, and assigns, or such others as I, the
said Moses Poole, my exors, admors, or assigns, should at any time agree with
and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, the Invention of
"IMPROVEMENTS IN ANCHORS AND IN FRICTION ROLLERS, TO FACILITATE THE LOWER-
ING AND RAISING SUCH AND OTHER ANCHORS, WHICH FRICTION ROLLERS ARE ALSO
APPLICABLE TO OTHER PURPOSES," communicated to me by a certain Foreigner
residing abroad; in which said Letters Patent is contained a proviso that I,
the said Moses Poole, shall cause a particular description of the nature of
the said Invention, and in what manner the same is to be performed, to be
inrolled in His said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.

page_text: tained in and by the following statement thereof, reference being had to the
Drawing hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
The Invention relates,-
First, to the application of guards to the flukes of anchors, whereby the
cables are less liable to foul in the shifting of the position of the ship or vessel
when riding at anchor.
Secondly, to reducing the friction of the axes of a windlass, by causing such
axes to be suported by a bearing of spheres, and which modes of reducing
friction is generally applicable for reducing the friction of axes or such like
surfaces turning in and supported by bearings.
DESCRIPTION OF THE DRAWING.
Figure 1 represents an anchor having the improvements applied thereto,
consisting of guards proceeding from fluke to fluke; these guards a, a, con-
sisting of bars of iron, which are affixed by rivets or other suitable means to
the flukes b, there being a guard on each side of the anchor; and in order
to give sufficient strength to such guards there is to each a projection c, which
entering into, are retained in holes formed at the side of the anchor for that
purpose. By this means it will readily be understood, that in case of the vessel's
swinging in such manner as would, with an anchor without guards, cause the
cable to pass around the upper fluke and foul the same, when the guards are
employed the cable would be guided off from the fluke and prevented fouling,
and hence the injurious consequences of such fouling will be prevented by
the application of the guards above described. And it should be remarked,
that although bars a, a, leaving a space between them and the anchor, have
been described, and which is considered the best arrangement and construction,
as it facilitates the fishing of the anchor, yet it will be evident that plates of
metal, förmed in such manner as to be fixed to the flukes and capable of guiding
off the cable under like circumstances to those above described, may be applied
without leaving spaces between them and the anchor. It is not, therefore, in-
tended to confine the claim to the precise shape of the guards, but generally to
claim the application of guards to the flukes of anchors, for the purpose of
guiding off the cables therefrom, and thus preventing their fouling, as above
described. Figure 2 represents the longitudinal section of a bearing for the axle
of a windlass, and Figure 3 is a plan thereof. a, a, are a number of spheres

page_text: placed around the axle 6 of a windlass, and c is a cylindrical case which retains
the spheres in their proper positions, there being a flange d at one end, through
which the axle passes, and a plate e at the other end, to prevent the spheres
falling out of their places. These spheres touching each other, and also
touching the axle all round, become the bearing of such axle. But in bearing
the same they offer but little friction thereto; and it will be evident that a
windlass, having its axes turning in bearings composed of such friction rollers,
will, from the great reduction of friction, greatly facilitate the raising and
lowering of anchors, and may also be applied generally in machinery as the
bearings of axles and shafts. And it should be understood that what is
claimed as the second part of the Invention, is the application of a series of
spheres as friction rollers, to facilitate the raising and lowering of anchors,
and also applicable to other purposes, as above described.
In witness whereof, I, the said Moses Poole, have hereunto set my
hand and seal, this Fourteenth day of March, in the year of our Lord
One thousand eight hundred and thirty-seven
