CHAPTER VII

DETAILS OF TIMBER BUILDINGS

Post and truss buildings with aisles—Roofs without ridge-pieces—The old
German sparrendach—Rearing and the rearing supper—Movable build-
ings—The reason, pan or wall-plate—Purlins and rafters.

Unlike the buildings on crucks, the post and truss buildings
could be conveniently widened by the addition of side aisles. In
order to effect this, lower posts were placed at such a distance away
from the principal posts as to give the required width to the
building. The principal posts then corresponded to the columns of
a church arcade, and the smaller posts took the place of the aisle
walls. The roof was formed by continuing the principal rafter of the
central aisle down to the heads of the outer posts, and a wall-plate
and a tie-beam were framed together upon them, as in a single aisle
building, and the strutting and bracing also agreed. The tie-
beam of the side aisles was run against the principal post and was
morticed into it. In Fig. 41 the central aisle of the great barn at
Gunthwaite, near Penistone, South Yorkshire, is shown. In date
these timber barns with aisles extend to the fourteenth century, of
which period there are examples still existing in England. Whitakerl,
the historian of much of the North of England, thought that they
succeeded the barns built on crucks, and that is the case in South
Yorkshire, where they are contemporary with the post and truss
buildings without aisles. \Vhere a larger building was needed the
aisles of the post and truss building provided a method of lateral
extension, in place of the unavoidable lengthening of the building
on crucks.

In the time of King Henry VIII there was a kind of post and
truss building constructed in South Yorkshire which differed from
the normal type, already described. The principal difference is in
