Safety disconnect for the pedal operator rod of an attaching machine

摘要

A mechanical disconnect for the pedal operating rod of an attaching machine comprises a stationary trip slide having a downwardly inclined cam surface and a housing enclosing the trip slide and reciprocable thereon. The housing is connected to the clutch operating rod. The housing also includes a transverse trip spacer pin and a latch having a follower nose engaging the cam and a central L-shaped opening receiving the pin in the horizontal leg of the opening. A spring urges the latch toward the slide. When the pedal is depressed, the latch pulls down the housing so that the clutch activating pull down rod moves away from the clutch dog. Further downward movement of the pedal cams the latch away from the slide so that the spacer pin aligns with the vertical leg of the "L" permitting the housing to pop up and the pull down rod to engage a clutch dog.
