Abstract: Apparatus for washing and vacuum drying long necked laboratory flasks is presented. The apparatus includes a cabinet which presents a washing and drying compartment and a pump and rotary spray arm. A special rack which can be rolled into and out of the compartment includes a central manifold and a plurality of distribution arms extending radially from the manifold. Upright spindle tubes extend from the distribution arms to receive the inverted flasks such at that the tubes extend through the narrow necks of the flasks with the open ends of the tubes located within the bodies of the flasks. A diaphragm coupling allows water to be pumped to the manifold for delivery to the spindle tubes during washing and rinsing cycles. The tubes spray the water directly inside of the flask bodies for thorough washing and rinsing. A vacuum conduit extending from the manifold carries a seat which engages a gasket to couple the manifold with a vacuum blower when the rack is moved into the cabinet.

Abstract: Product storing and dispensing apparatus for the improved handling of products such as gum and mints is provided and especially suited for use in multi-product, selective vending machines of types that store and dispense a variety of products from compartmented drawers, which must be withdrawn for practical reloading with products. The improved apparatus conserves space and minimizes the weight of the structure to be moved during loading by substituting for the conventional drawer unit a lower assembly that carries the operating mechanism for selective product dispensing and may remain within the machine during loading and an upper assembly that merely receives products, is shiftably mounted on the lower assembly and alone need be withdrawn during loading.
