Compensating anvil means for a printing machine

Claim 1

IN A PRINTING DEVICE OF THE CHARACTER DESCRIBED HAVING A PRESSURE APPLYING MEMBER ADAPTED TO BEAR ON THE TYPE FACE AREA OF A TYPE CARRIER AND A PRINT RECEIVING MEDIUM DISPOSED IN SUPERPOSED RELATION TO EACH OTHER AT A PRINT STATION, SAID PRESSURE APPLYING MEMBER BEING IN THE FORM OF A CYLINDRICAL ROLLER GUIDED FOR TRAVEL ACROSS SAID PRINT STATION, AN ANVIL DISPOSED AT SAID PRINT STATION TO SUPPORT SAID CARRIER AND SAID MEDIUM FOR PRESSURE ENGAGEMENT WITH SAID MEMBER, SAID ANVIL INCLUDING A HEAD SECTION PRESENTING A FLAT FORCE RESISTING SURFACE OF AN AREA AT LEAST COEXTENSIVE WITH TYPE FACE AREA OF SAID CARRIER AND A BASE SECTION PRESENTING A SUBSTANTIALLY RECTANGULAR SURFACE WITHIN A PLANE PARALLEL TO THE PLANE OF SAID FORCE RESISTING SURFACE, SAID FORCE RESISTING SURFACE BEING SMALLER IN AREA THAN THE SURFACE AREA OF SAID BASE SECTION AND LYING WITHIN THE BOUNDARIES DEFINED BY THE EDGES OF SAID BASE SECTION SURFACE WHEN PROJECTED IN A DIRECTION PARALLEL TO THE DIRECTION IN WHICH THE FORCE OF SAID PRESSURE APPLYING MEMBER IS EXERTED, MEANS FOR ADJUSTING THE PLANE OF SAID FORCE RESISTING SURFACES TO RECEIVER THE FORCE EXERTED BY SAID PRESSURE APPLYING MEMBER UNIFORMLY WITHIN ANY DISCRETE AREA OF THE CARRIER SUPPORTED BY SAID FORCE RESISTING SURFACE, SAID ADJUSTING MEANS INCLUDING A PLURALITY OF LEVERS INCLUDING A SEPARATE ONE FOR SUPPORTING EACH CORNER OF THE SURFACE AREA OF SAID BASE SECTION, EACH LEVER BEING INDIVIDUALLY ADJUSTABLE TO DISPOSE AND FORCE RESISTING SURFACE IN A PLANE PARALLEL TO THE PATH DEFINED BY THE PERIPHERY OF SAID ROLLER WHEN TRAVERSING SAID PRINT STATION, AND YIELDABLE RESISTANCE MEANS INCLUDING A RESISTANCE MEMBER COMMON TO ALL SAID LEVERS AND COUPLED THERETO PROVIDING A REACTIVE FORCE ON SAID ANVIL THROUGH SAID LEVERS IN OPPOSITION TO THE FORCE EXERTED BY SAID PRESSURE APPLYING MEMBER FOR ENABLING SAID ANVIL TO YIELD UNDER FORCE EXERTED BY THE PRESSURE APPLYING MEMBER IN EXCESS OF A PREDETERMINED AMOUNT, THE YIELDING MOVEMENT OF SAID ANVIL BEING IN THE DIRECTION IN WHICH SAID FORCE IS APPLIED AN WITHOUT ALTERNATION OF THE ADJUSTED PLANAR ORIENTATION OF THE FORCE RESISTING SURFACE THEREOF, WHEREBY SUBSTANTIALLY THE SAME PRESSURE IS UNIFORMLY APPLIED TO TYPE FACE CARRIES AND PRINT RECEIVING MEDIA HAVING COMBINED THICKNESS OF VARYING AMOUNT.
