Abstract: Drive-in banks, some large service stations and similar operations use cashiers windows located on small islands at a remote place from the central building. A concealed transport system is located below the floor of the main building and employs a carrier box mounted on rollers which operate on flanged tracks mounted on the sides of a small tunnel which extends beneath the respective casher's booths each of which has an access door in the floor to reach the tunnel. A nylon cable attached at its opposite ends to the carrier extends around a large drive wheel pulley inside the main building and across various idler pulleys in the ends of the tunnel.
