A side guide device adjustably positioned between two laterally spaced frame members includes a pair of side guide plates, each having vertical and horizontal members and a transverse mounting plate. A pair of rail members are mounted on the laterally spaced frame members. Each of the rail members includes a longitudinal groove wherein ends of the transverse mounting plate are adjustably positioned within the grooves of the rail members whereby the side guide members are positionable longitudinally. The transverse mounting plate includes at least two lateral slots through which the side guide members are adjustably mounted whereby the side guide members are positionable laterally. There is structure for locking the transverse mounting plate at a fixed position in the grooves of the rail members. The side guide plates are mounted below the locking plate.
