Claims22
A hand-held stamp for printing on a surface, the stamp comprising
- an endless substrate having a raised printing surface, and
- a mechanism for allowing said substrate to rotate as said printing surface is rolled across said surface and said printing surface is simultaneously inked from two or more porous-point markers held to ink a printing surface wider then the nib of one of said markers.
A hand-held roller stamp comprising
- a wheel having a raised printing surface,
- a housing holding said wheel and permitting said wheel to rotate, said housing being configured to hold a porous-point marker having a nib positioned to continuously ink said printing surface, said marker having a capping crown, said housing comprising a sleeve to hold said capping crown, and
- a cap configured to mate to said stamp to provide an airtight seal of said marker.
A hand-held roller stamp comprising
- a wheel having a raised printing surface,
- a housing holding said wheel and permitting said wheel to rotate, said housing being configured to hold a porous-point marker having a nib positioned to continuously ink said printing surface, said marker having a capping crown, said housing comprising a sleeve to hold said capping crown, and
- a case to hold said stamp, said case configured to mate to said stamp to provide an airtight seal of said marker.
A hand-held roller stamp comprising
- a wheel having a raised printing surface, and
- a housing holding said wheel and permitting said wheel to rotate, said housing being configured to hold a porous-point marker having a nib positioned to continuously ink said printing surface, said marker having a capping crown, said housing comprising a sleeve to hold said capping crown, said sleeve comprising crush ribs projecting from an inner surface of said sleeve.
A hand-held roller stamp comprising
- a wheel having a raised printing surface, and
- a housing holding said wheel and permitting said wheel to rotate, said housing being configured to hold a porous-point marker having a nib comprising a marking surface with a broad dimension and a narrow dimension, said marker being held with said broad dimension parallel to a rotational axis of said wheel.
A hand-held roller stamp for transferring ink to a surface comprising
- a wheel having a raised printing surface and an axle having two ends, and
- a housing holding said wheel and permitting said wheel to rotate, said housing being configured to hold a porous-point marker having a nib positioned to continuously ink said printing surface, said housing comprises cavities to retain the ends of the axle of said wheel, said cavities being configured to allow said wheel to move toward or away from said nib while ink is being transferred to said surface.
