Vertical mold for making textured concrete panels

An adjustable, reusable mold for forming concrete slabs comprising:

• a first concrete impervious form member;
• a concrete impervious base member provided with a plurality of slots and having an upper surface;
• means for fixedly supporting said first form member in a generally upright position on the upper surface of said base member, said fixedly supporting means including first engagement means:
• a second concrete impervious form member;
• means for supporting said second member in a generally upright position and for mounting said second member for movement toward and away from said first fixed member along a path generally parallel to said upper surface of said base member, said path comprising a plurality of rails extending into the respective slots in said base member and said supporting and mounting means comprises a wheeled carriage adapted to roll on said rails, said carriage including a plurality of second engagement means adapted to be extended through said slots and interlock with said first engagement means;
• means for releasably coupling said second member at a pre-determined distance from said first member on said base member;
• a pair of concrete impervious side members movable into closing relationship to the side opening defined by said first and second members;
• means for retaining said pair of side members in fluid-tight engagement with said first and second upright members and said base member;
• and resilient liners secured to and overlying said first and second form members to provide a textural pattern to said concrete slab.
