Abstract
A hand operated ink stamp comprising an outer casing having an open bottom and an opening in the upper surface. A printing die impregnated with ink is disposed within the casing and is carried by a die holder having an upper magnetically susceptible surface. Mounted within the upper portion of the casing is a magnet, and the magnetic force will hold the die holder and die at a raised position above the surface to be printed. A stem is mounted for sliding movement in the opening in the upper surface of the casing and is connected through a ball and socket joint to the die holder. Manually depressing the stem will overcome the magnetic force to release the die holder from the magnet and cause the die to contact the surface to be printed. The position of the magnet within the casing can be adjusted to thereby vary the printing impression.
