A paint wagon (10) has a base (22) having a plurality of wheels (28, 30) mounted in supporting relation thereto. A drop pin (32) is slidably mounted to the base. The drop pin (32) selectively engages with a conveyor (12) for translating the paint wagon (10) along a path. A plurality of slidably mount ed mounting fixtures (26) are movable between a contracted position and an expanded position. An actuating assembly (24) slidably mounts the mounting fixtures to the base. The actuating assembly (24) has a longitudinal support (38) and a plurality of cars (52, 54, 56) in sliding engagement with the longitudinal support. The mounting fixtures (26) extend from the plurality o f cars. A rotatably mounted pinion (70) drivingly engages a rack (84, 86) whic h is slidably mounted with the longitudinal support. The rack (84, 86) is connected to an outer car (56). The rack has a plurality of tabs (90, 92) extending therefrom positioned to selectively engage inner cars (52, 54) to move the inner cars and automatically space the cars. An actuating mechanism (20) is mounted on the path. The actuating assembly (24) selectively engages the actuating mechanism (20) as the paint wagon (10) travels along the path to effect rotation of the pinion (70) and responsively effect the movement of t he mounting fixtures (26) between the contracted and expanded positions.</SDOAB >
