ABSTRACT:
There is disclosed a printing saddle including a semicylindrical shell formed interiorly with a rocker arm recess projecting axially from the mid-portion thereof to one end thereof and also a circumferentially extending link recess projecting from the inner extremity of the rocker arm recess to one side of the shell. A biasing bar is mounted along such one side of the shell and is biased thereaway from by means of biasing springs. An elongated rocker arm is received in the rocker arm recess and pivotally mounted medially from the shell and has its inner extremity connected with the biasing bar by means of an arcuate link received in such link recess. A lock is mounted from the shell adjacent the free end of the rocker arm and is engaged by such free end upon rotation of the rocker arm to retract the biasing bar to its retracted position to thus lock such biasing bar in its retracted position. A lever handle may be provided for engagement with the free end of the rocker arm to retract such rocker arm.
