Abstract: A service box for deposit of valuables for a subsequent feed down through a delivery aperture to a vault or safe chamber. The service box has an insert aperture with a lockable insert aperture closure. The service box below the insert aperture has a fixed base projecting approximately halfway to the back wall and providing the delivery aperture and includes an inner box formed by a roof, side walls and back wall, with open front and open base. The inner box is mechanically reciprocable and a scraper, fixed on a side of the inner box near its open end, reciprocates with the inner box back along the service box fixed base. A sliding hatch which slides horizontally is located below the service box fixed base for closing and opening the delivery aperture, being connected to the inner box by linkage so movement of the sliding hatch and of the inner box is in opposite directions. An electric motor is used to reciprocate the inner box and the sliding hatch.
