Abstract

A lock comprised of a cylindrical body having a first passage extending axially through the body which passage is configured to enable a locking bar to be passed through the body, the bar having at least one orifice intermediate its extremities, the lock body having a second partial passageway extending from the side wall of the body at least into the first passageway and normal to the latter so that the orifice in the bar can be disposed in register with the second passageway. A cylindrical lock configured to fit slidably in the second passageway so that at least a portion of the lock may be thrust in the second passageway and through the bar orifice when the latter is disposed in register with the second passageway, when the lock may be secured by a key to be withdrawn from the outer end of the lock. This lock and bar may employed with external plates to secure adjacent members from movement relative to each other.

4. The means for securing two abutting members against relative movement to each other as defined in claim 3, wherein

second passageway in the lock body extends for a further distance beyond the first passageway and into the lock body, and the lock plunger, in its second position extends through said first passageway and into the further distance beyond said first passageway and into the lock body.
