by iron or wood work, to keep off rain, as an awning is used to keep off
the sun.--_To tilt._ To lift up a little on one side or end of anything.

TILT-BOAT. One expressly fitted like a tilt-waggon, to preserve powder
or other fragile stores from the weather.

_floor-timbers_, _cross-pieces_, _futtocks_, _frames_, and the like (all
which see).

TIMBER AND ROOM, is the distance between two adjoining timbers, which
always contain the breadth of two timbers, and two or three inches
besides. The same as _room and space_, or _berth and space_.

TIMBER-CONVERTER. A dockyard official who has the charge of converting
timber for its different purposes in ship-building.

TIMBER-HEADS. The heads of the timbers that rise above the decks, and
are used for belaying hawsers, large ropes, &c. (_See_ KEVEL-HEADS.)

obliquely on the keel towards the extremities of a ship, forming the
dead solid wood of the gripe, and of the after heel.--_Filling timbers._
Those which are put up between the frames. One mould serves for
two timbers, the fore-side of the one being supposed to unite with

the hindmost on the quarter are termed _fashion-pieces_.

TIMBER-TASTER. One appointed to examine and pronounce upon the fitness
