ABSTRACT:
Combination stamp comrpises a plurality of independent stamp elements joined together for use in combination. The stamp element includes a stamp frame having a stamp plate at its lower end and a top wall and four side walls. A dovetail-like vertical projection is formed on one of the opposing side walls and a dovetail-like vertical groove in the other side wall. Engagement of the projection in the groove joins adjacent stamp elements together against horizontal displacement. Each of the other opposing side walls has a horizontal groove in its upper portion. The joined stamp elements are so adjusted that the horizontal grooves therein are in alignment with each other, and a cover having inward projections along the opposite side edges thereof is fitted over the stamp elements, with the inward projections engaged in the aligned horizontal grooves, whereby the stamp elements are prevented from vertical displacement.
