Abstract
Abstract A hand stamp stenciling printing implement or duplicator having an inking pad held in a cap, with the pad projecting down below the cap. The cap has a central opening and a tubular stem extending up from the cap in communication with the opening. The stem is internally and externally threaded. A cover plate is provided on top of the cap having an opening receiving the stem. A nut is threaded externally on the stem for clamping the cover plate on the cap. A plastic squeeze bottle containing ink is threaded internally in the stem. Brackets are provided at opposite ends of the cover plate having tongues extending therefrom between the cover plate and the cap and clamped therebetween by the nut, these brackets carrying retractable spring-biased legs for holding the pad raised above a supporting surface, the implement being adapted to be pushed down toward a supporting surface via retraction of the legs against the spring bias.
