Abstract: A manually operated self-inking stamping device including a base for contacting material to be stamped, a stamp pad received by the base and having a shaft extending outwardly therethrough, a handle threadedly mounted on the shaft for rotational positioning movement therealong, and a locking member extending between and normally lockingly engaging the handle and the base. A coiled spring is disposed about the shaft between the handle and the locking member to bias the handle and the stamp pad upwardly and to maintain the locking member and the base in engagement. Ordinary operation is achieved by depression of the handle against the biasing of the spring.
