Gallows

In wooden presses, a frame made of two pieces of wood and a transverse piece, placed behind the tympans, to support them at a proper angle when they are turned up. The transverse piece is nearly as long as the tympans are wide, so that the frame can rest upon it: they are inclined towards the tympans and form an abutment, and are placed in sockets so as to be easily taken out when necessary.
