Abstract
Abstract A stamping device characterized by an inner frame substantially closed at its bottom end and providing a positive support for an ink storage block and a stamping block disposed thereunder to prevent any appreciable warpage or deformation of those two blocks when the lower surface of the stamping block is pressed against the object on which an impression is to be produced. The inner frame is further provided at the bottom end or wall thereof with an aperture or apertures, and a plurality of grooves communicating with the aperture or apertures. These apertures and grooves serve as passages for an enhanced supply of ink and also as passages for the air flowing down through the inner frame into the ink storage block to thereby push down the ink into the stamping block as the volume of the ink contained in the stamping block decreases. The device is especially useful when used with a continuous stamping machine for a variety of applications.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
239 words
A stamping device adapted for continuous and high speed operation comprising: a cylindrical outer frame open at upper and lower ends, and having an inwardly directed flange at its lower end, and an annular shoulder on its upper end on the interior thereof; a generally mating inner frame received in said outer frame and defining a hollow cavity therein for receiving and holding ink, said inner frame having an open upper end for receiving ink therethrough, and an annular shoulder on its upper outer wall which is complimentarily shaped to said annular shoulder on said outer frame, and a transverse bottom wall provided with an inwardly and downwardly inclined inner surface defining the bottom of said hollow cavity; aperture means opening through said groove means on the face of said inner surface communicating with said aperture means; ink storage means formed of porous materials and received adjacent to said aperture means for storing ink; stamping means formed of porous material and disposed beneath said ink storage means, supported on said flange of said outer frame, and having an exposed face projecting downwardly below the under surface of said flange of said outer frame and adapted to be wetted by ink from said ink storage means; and, wherein said outer frame includes an outer annular shoulder adjacent to said inner annular shoulder on the exterior thereof, said outer annular shoulder providing means for connecting said device with a stamping machine.

Claim 3
Dependent Claim
86 words
The apparatus of claim 1 wherein said stamping means is contacted with said ink storage means and has a frustoconical lower portion projecting downwardly through said lower end of said outer frame and adapted to be wetted by ink from said ink storage block, and a downwardly facing annular shoulder is formed between said upper and lower portions of said stamping block and above said flange of said outer frame and engageable with said flange of said outer frame to hold said stamping block in position.
