Abstract
An auxiliary lock comprises a latch assembly having an elongated casing to be received by a first horizontal bore extending into the end of the door. A cylinder mechanism is received by a second horizontal thru bore extending, from one face of the door to the other face of the door and intersecting the first bore. The cylinder mechanism includes a cylinder having a chimney, a cylindrical guard having an annular door engaging surface, an annular lip projecting inwardly from the annular door engaging surface to be received by the second thru bore, a cylindrical segment projecting inwardly from the annular lip, and a strut projecting radially upwardly from one circumferential end of the segment and defining therewith a shaped structure. The strut has a length selected so that the shaped structure lies proximate the bottom of the casing to thereby prevent the rotation of the said guard.
