Our invention relates to the gaff jaws used in the fore and aft rigging of
fishing smacks, yachts, and other vessels; and its object is to effect improve-
ments in or relating to the tumblers fitted in or to such jaws, whereby the usual
wear of the mast is greatly reduced, and the raising and lowering of the spar
is rendered easy and smooth.
According to our invention we fit to the jaws of the gaff a semicylindrical or
This
approximately semicylindrical plate of metal or other suitable material.
plate is pivoted to the jaws by means of a lug or other projection or projections
attached thereto or integral therewith, in such a manner that it is always
parallel with the mast at any angle the spar may assume relatively thereto.
The plate is lined with leather or other suitable material for reducing friction.
Our invention is equally applicable to straight and bent jaws, the pivot or
pivots enabling the tumbler to accommodate itself to the mast in any position
of the spar.

of metal or other suitable material, secured to the lug d by screws or rivets.
The plate may be made of steel, brass, or other suitable material, and is
lined with leather as shown at g or with other suitable material for reducing
friction. The ends of the jaws are also similarly lined at g¹ for the same
purpose.
The plate slides up and down the mast and remains in a position parallel
therewith at any angle the spar may assume relatively thereto.
The lug and plate f may be made of metal and in one piece or otherwise
united.
Our invention is equally applicable to straight and bent or curved jaws, the
pivot or pivots enabling the tumbler to accommodate itself to the mast in any
position of the spar.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is;
-
In gaff jaws of sailing and other vessels the combination therewith of a
tumbler consisting of a lug pivoted to the jaws; a suitably curved plate of
metal or other suitable material attached to or integral with the lug; and
leather or other lining to the plate and jaws, substantially as and for the purposes
described.
