[Origin uncertain.
Perhaps originating as a jocular antithesis to the summer or upper rail or cross-bar of the hand-printing press (SUMMER sb.2 3 e). Connection with north. dial winter = trivet is uncertain.]
In a hand-printing press, a block of wood about nine inches broad by nine deep, supporting the carriage and having a tenon at each end to fit into corresponding mortices in the cheeks.
