DEFINITION

Classification: 221/15

(under the class definition) Article dispensers having means which substantially limits or retards the period of operation of a discharging means or the period between successive operations of a discharging means to a predetermined time interval.

(1) Note. Devices in which the time for complete cycles of operation is predetermined solely by the speed at which the actuator for the discharging means is operated are excluded and are classified in appropriate subclasses below. However, the specific provision of structure having the disclosed function of causing a pause or retardation of motion during a portion of each cycle is included. The provision for lost motion in an actuating linkage is not considered to be delay mechanism within the meaning of this subclass definition, it being required for classification here that some structure other than the actuating linkage or mechanism itself be provided to cause and/or control a time delay in the operation of the device.
