Patent ID: 8186268

Claim:
A roller press comprising: a pair of spaced apart bearing blocks having grooves; a first roller supported by the bearing blocks for rotation about a first axis, the first roller having an outer press surface; a second roller supported by the bearing blocks below the first roller for rotation about a second axis, the second roller having an outer press surface spaced apart from the first roller press surface for pressing media therebetween; a first gear fixed to the first roller having gear teeth; a second gear fixed to the second roller having gear teeth meshing with first roller gear teeth rotating the second roller in a rotational direction opposite the first roller; a handle connected to the first roller, the handle having a ratchet mechanism turning the first roller in a first rotational direction R 1 as the handle is moved in a first direction H 1 and not turning the first roller as the handle is moved in a second direction H 2 opposite the first direction H 1 , wherein the ratchet mechanism includes reverse action means for enabling the ratchet mechanism to turn the first roller in a second rotational direction R 2 as the handle is moved in the second direction H 2 and to not turn the first roller as the handle is moved in the first direction H 1 ; a feed bed disposed between the bearing blocks and received in the grooves, the feed bed having a surface for supporting media thereon and a first end disposed adjacent to the second roller and below the second roller press surface; and an exit bed disposed between the bearing blocks and received in the grooves, the exit bed having a surface for supporting media thereon and a first end disposed adjacent to the second roller opposite the feed bed and below the second roller press surface.
