US 6484866 B1Abstract
To prevent adjacent conveyor carts 20 from separating should the hitch mechanism 32 accidentally break or become uncoupled, an auxiliary cart connector 34 is preferably connected between the trailer frame structures 22 of adjacent carts 20. In the preferred embodiment, the auxiliary cart connector 34 is a metal cable or lanyard, although other high-tensile strength materials could be used. In the embodiment depicted, the auxiliary cart connector 34 is an approximately {fraction (3/16)}th inch thick metal cable connected to adjacent trailer frame structures 22 with metal mounting connectors 34 a. The primary reason that metal is the preferred material for the auxiliary cart connector 34, besides its strength, is so that the auxiliary cart connector 34 will also serve as a continuous electrical connector between adjacent carts 20. Electrical continuity between carts 20 is important because of static electricity build-up while the carts 20 are traveling around the conveyor track 12. However, because the cam followers 30 a,b,c are preferably formed of polyurethane (an electrical insulator) and because the components of the hitch mechanism 32 are preferably coated with TEFLON® (also an electrical insulator), electrical continuity between adjacent carts 20 would not otherwise be effectively achieved. By electrically connecting the carts 20, static charges can be bled off from the train, which is important for safety and operational considerations. Thus, the auxiliary cart connector 34 serves two important purposes: first, it physically attaches two adjacent conveyor carts 20 and prevents them from becoming completely separated should the hitch mechanism 32 fail; second, it enables electrical continuity among all of the conveyor carts 20 in the train.
