HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Patent Agents, of
67, Strand, in the City of Westminster, Civil Engineer. IMPROVEMENTS IN GAFF
FASTENINGS FOR VESSELS." A communication from abroad by James Henry David,
of Damariscotta, State of Maine, United States of America."
The Invention consists in fastening the gaff to the mast of a vessel with a parral
so that the gaff and sail will readily and easily fall whatever the position of the
gaff may be without chafing or catching the mast in its descent, and whereby they
may be as easily and readily raised to position.
The gaff is to be held to the mast by chafe-guards, parrals, and a ring, the parrals
may be of wood, leather, or metal, or a combination of same, and are placed on tho
ring at certain distances apart, and held apart by sleeves. Thoy are also held in
position by a rope passing through holes in the top and bottom of the parral.
The parrals surround the mast about one-quarter of its circumference, and are
held about one-eighth of an inch away from the concave portion of the gaff to allow
the same to move freely up and down.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Herbert John Haddan in the Great Seal Patent Office on the 11th
November 1876.

The gaff is to be held to the mast by chafe-guards, parrals, and a ring, the parrals
may be of wood, leather, or metal, or a combination of same, and are placed on the
ring at certain distances apart, and held apart by sleeves. They are also held in
position by a rope passing through holes in the top and bottom of the parral.
The parrals surround the mast about one-quarter of its circunference, and arc
held about one-eighth of an inch away from the concave portion of the guff to allow
the same to move freely up and down.
The accompanying Drawing will show more fully how the Invention is to be
carried into effect.
Figure 1 is a side view of a gaff embodying my Invention; Figure 2 is a plan
view of the same.
A is a mast, B is the gaff, held to the mast by the chafe-guards E and F, parrals
C, C, and ring D. The parrels C, C, are made of wood, leather, or metal, or a
combination of the same, and are placed upon the ring D at certain distances apart,
and are held apart by sleeves d. They are also held in position by a rope e passing
through holes in the top and bottom of the parral. The guard E is pivoted in a
slot b to the gaff by a pin b', and is held in position by the ring D and rope e.
guard F is placed opposite the guard E, and is pivoted or hung on the ring D. It
also serves as a button to hold the ends of the ring D, and is provided with an
opening for the insertion of the nuts which are placed upon the ends of the ring
and serve to tighten the ring around the mast.
The
I do not wish to be understood as confining myself to the above mode of
fastening the end of the ring, it can be done from the side. The ends of the ring
may meet in one of the parrals, into which an insertion may be made for the
reception of the nuts ff; this mode of fastening and tightening the ring is just as
effectual as the one shown in the Drawing and described in the fore part of the
Specification.
Having thus described my Invention, I desire to claim the guard E, parrals
C, C, guard F, with opening g, in combination with the ring D, nutts f, f, rope c,
gaff B, with opening 6, and mast A, substantially as and for the purpose set forth.
In witness whereof, I, the said Herbert Jolin Haddan, have hereunto set my
hand and seal, this Tenth day of November, in the year of our Lord One
thousand eight hundred and seventy-six.
