Abstract A stamping device for providing ink to a stamp die supported by a frame movable between a first position wherein the stamp die is in contact with an ink pad through an opening in an envelope that otherwise completely encloses the ink pad, and a second position wherein the frame is shifted downwardly to disengage the stamp die from the ink pad. The frame is attached to the stamping device in such a manner that downward movement of the stamp die away from the ink pad results in the movable frame being rotated 180* to move the stamp die into a position for further downward movement toward a stamping operation. Tensioning means are provided for urging a sealing member, carried by the movable frame and circumscribing the stamp die, into engagement with the outer surface of the envelope to provide a seal around the envelope opening, thereby preventing a premature drying of the ink carried by the ink pad.
A stamping device comprising a compressible ink pad and a holder for holding said ink pad, a carrier member and a stamp die carried by said carrier member, means normally urging said stamp die upwardly toward a first position in which said stamp die is in engagement with said ink pad, a handle for grasping said stamping device and for imparting movement to said stamping device to urge said stamp die downwardly toward a second position away from said ink pad and into engagement with an article to be marked, a fluid impervious envelope enclosing said stamp pad except for an opening positioned to permit said stamp die to register with said stamp pad through said opening, when said stamp die is in said first position, said envelope being disposed intermediate said ink pad and said holder and being of a plastic material, said carrier member having walls formed around said stamp die and extending upwardly from said carrier member a distance slightly below the upper edges of said stamp die to engage and plastically deform said envelope into said compressible ink pad to form a seal completely enclosing said opening when said stamp die is in said first position in engagement with said ink pad to prevent evaporation of ink from said ink pad.
