Abstract
Abstract A quick change indicia display for patterns and the like having a base plate whose top surface is stepped down at one end, and which has a longitudinally extending keyway proceeding therefrom towards the opposite end. The sidewalls of the keyway adjacent the stepped down portion are parallel, and the indicia are formed on the top surface of indicia plates adapted to overlie the entire width of the base plate. The indicia plates have projections on the bottom thereof which extend down into the keyway and which have a longitudinal extent that is a fraction of that of the indicia plate; so that the indicia plate can be slid to a position overlying the parallel sidewall portion of the groove in the base plate and removed. The combined assembly above described is recessed into a pattern or the like, so that the indicia carried by the indicia plate will become an imprint in the molds produced therefrom.
