Suspension for a device serving as a guard in front of the printing-unit cylinders of a printing machine

A printing machine comprising:

• a frame;
• a plate cylinder supported within said frame;
• an ink fountain for storing printing ink;
• transfer rolls for transferring printing ink from said ink fountain to said plate cylinder, said transfer rolls including an ink fountain roller, said ink fountain being moveable between an operating position in which said ink fountain roller communicates with said ink fountain and a throw-off position in which said ink fountain roller does not communicate with said ink fountain;
• a guard mechanism for impeding access to said plate cylinder and ink fountain from outside of said printing machine, said guard mechanism including a guard plate, said guard plate being movable independently of said ink fountain between a first position which impedes access to the interior printing machine and the plate cylinder and ink fountain located therein and a second position which permits access to an interior of said printing machine and said plate cylinder and ink fountain, and said guard plate being connected to said ink fountain such that upon movement of said ink fountain to said throw-off position said guard plate is simultaneously moved to a position which prevents the possibility of said ink fountain from interfering with movement of said guard plate between its first and second positions and which prevents the possibility of said guard plate from interfering with movement of said ink fountain from said operating position to said throw-off position.
