Claim:
An apparatus attachable to a vehicle for movement adjacent to a generally vertical wall structure for imprinting a pattern in a surface of the wall structure comprising: an imprint form that is attached to an imprint form frame; a support frame of generally rectangular form that has at least two horizontal members attached to at least two vertical members and to which said imprint form frame is attached; said support frame movably attached to a position support member to allow movement horizontally, vertically and perpendicularly relative to the plane of said support frame wherein perpendicular movement is controlled by an imprint actuator; and said position support member movably attached to a frame support beam that is oriented generally vertically to allow movement of said positioning support member in a generally vertical direction; wherein: said position support member has a bar member with a frame bar attached orthogonally at each end; a junction device has a first sleeve attached orthogonally to a second sleeve to be slidably disposed on each of said horizontal members wherein said first sleeve of each junction device is slidably disposed on each horizontal member, and said second sleeve is slidably disposed on one of each of said frame bars; and said support frame is movable and fixable in the horizontal direction and said imprint actuator is attached to each of said junction devices and to each of said frame bars.
