Abstract
A lockout safety device used in combination with a conveyor pullcord syst The device is used to tension and then lock the conveyor system's pullcord in the tensioned position which action renders the conveyor inoperative. Several embodiments are disclosed each of which is portable, simple in structure, inexpensive, compact in size, and useable anywhere along the length of the pullcord. Each functions to cam its surface against and thereby tension the pullcord which then allows it to be locked in that position. In the preferred embodiment, two sets of parallel members are pivotably joined together with each set having a pin to engage the pullcord on one side while the pivot engages it on the other side.
