The decorative underside of the top rail on a traditional handmade
farm wrought iron gate. In Britain, it is possible to date a farm
gate and make a good guess at where it was made by the design
of the carved jowl. The jowl gives a taper to the top rail, so
that the part nearest the hinge, which carries most of the strain,
is heavier and more substantial.
A joint used when the vertical slats or muntins are to be cut
in flush with the top rail. Depending on the dimensions of the
wood, the slats are halved and the top rail is notched.
The two middle or mating tiles on a pair of carriage gates One
stile held against a stop by means of a sliding tower bolt, so
that, in effect, it becomes the gatepost against which the other
stile is closed.
Muntin and brace tenon
A compound joint formed at the point where the slats or muntins
meet the braces to be tenoned into a mortise that has been cut
into the underside of the top rail.
