A conveyer device includes a number of shafts coupled to a chain, and a number of platforms and beams rotatably coupled to the shafts. A number of springs are engaged on the shafts and are secured to the platforms and the beams for resiliently supporting the beams and for resiliently supporting the shoes between the beams. The beams are moved away from each other against the springs for supporting shoes of different sizes. The springs are not engaged between the beams such that the springs will not engage with the shoes supported between the beams.
