Abstract: A method and device in a conveyor for preventing the collision of guide pins on a transversely moving diverting shoe with the side of the conveyor in a conveyor having an endless conveying surface comprised of a plurality of surface members on which diverting shoes are slidably mounted to permit transverse movement thereon with respect to the direction of conveyance. The diverting shoes each have a downwardly depending guide pin which engages a rail network underlying the conveying surface. Magnets are positioned near the end of a diagonally oriented rail to attract the guide pins so as to prevent the transverse momentum of the guide pins and diverting shoes from carrying them into a collision with a stopping surface of the conveyor. The magnets are so positioned that non-diverted guide pins traveling adjacent the side of the conveyor are not substantially altered from their course of travel by the magnets.
