Adjustable self-inking stamping device

Abstract

A manual self-inking stamping device including a base for contacting material to be stamped, such base having a recess in which a self-inking stamp pad is supported for vertical movement with respect thereto. A depressable handle threadedly engages a shaft extending through the base from the stamp pad, and a movable member is disposed about the shaft for selective meshing engagement with the base at one end of the movable member and for engagement with the handle at the other end to lock the handle against rotational movement about the shaft. A spring disposed intermediately of the handle and the movable member urges the handle and the stamp pad upwardly and urges the movable member into engagement with the base. The handle may be depressed against the biasing force of the spring to bring the stamp pad into contact with the material to be stamped, the movable member acting as a stop to restrict the vertical depression of the handle. The stamping pressure which may be exerted against the material may be varied by adjusting the effective length of the shaft between the handle and the movable member by moving the movable member upwardly out of meshing engagement with the base and rotating the handle about the shaft.
