Abstract
Abstract Dating wheel with a tracer symbol unit which can be manually inserted on or removed from the wheel. To change the tracer symbol, the operator simply uses thumb and forefinger to grasp the unit and extract same and then replace with an identical unit having a different symbol. This can be done without slowing or stopping the cases or other medium being printed. There is no machine down-time.

In a rotary dating wheel including a main frame for mounting the wheel for rotation and removably supporting a stack of type-rings for removably supporting dating type thereon for printing dating symbols, the improvement comprising: a vertically extending key-way formed in said frame; a plurality of openings respectively formed in said type-rings, each type-ring having a pair of opposite edges forming its opening and the corresponding edges on one side of the type-rings being in substantial vertical alignment and the corresponding edges on the opposite side also being in substantial vertical alignment, said opposite edges and said main frame forming a channel; a carrier slidably mounted in said channel and having a key in said key-way for maintaining the carrier in the channel and providing for the carrier to be manually moved into and out of the channel; a plurality of segments of type-rings stacked on said carrier and extending between said opposite edges, the segments being for use in supporting type having a tracer symbol thereon to print a tracer symbol in conjunction with the printing of the dating symbols by said dating type; alignment means on said carrier for removably maintaining said segments in stacked condition on the carrier; clamp means on the carrier for clamping said segments in position; and lift means on said carrier to be grasped by the fingers of an operator for moving the carrier and a tracer symbol thereon in and out of said channel.
