Layout boards

A layout board for use with a dry transfer sheet comprising a rectangular board having an upper support surface, a straight track along one edge of the board, a first carriage mounted for sliding movement along said track, an arm on said first carriage extending perpendicular to said track and across said upper support surface, a second carriage mounted slidingly for movement along said arm, means dividing the movement of the second carriage along said arm into a plurality of equally spaced steps, and means mounted on said second carriage for supporting a rectangular dry transfer sheet, said dry transfer sheet extending in a first direction laterally of the arm and having transferable indicia thereon, the support means engaging an edge of the dry transfer sheet parallel with said arm, said first direction being parallel with said track, magnetic clamp means extending parallel to the arm and along one edge of the base board, said magnetic clamp means comprising a fixed strip and an angled bar movable with respect thereto in a direction perpendicular to said track, and said strip and bar being releasably held together by magnetic attraction and adapted to clamp a receptor sheet at one edge, the sheet then extending across the board in a second direction opposite said first direction, and an elongate target area of contrasting color located on said upper support surface, parallel to said track and extending from a position substantially at the center of said upper support surface towards said clamp means,

• whereby indicia can be transferred from said dry transfer sheet onto said receptor sheet in said target area.
