Patent ID: 7874189

Claim:
A four-way, field-reversible self-latching cabinet lock, comprising: a substantially planar bolt housing cover defining a substantially central aperture and a radially directed bore penetrating the aperture; a substantially hollow cylinder and plug assembly shell having a rear wall defining a circular plug aperture registrable with the central aperture and a rearwardly directed hub extending axially away from the plug aperture and sized for rotational receipt in the central aperture so that the shell is journaled for rotation with respect to the bolt housing cover; locking means for rotationally retaining and releasing the shell with respect to the bolt housing cover in one of four orthogonal operating positions; a cylinder and plug assembly removably received in the shell; a bolt housing reciprocally receiving a spring-biased latch bolt, the bolt housing adapted to removably receive the bolt housing cover; a rotary cam having a rear side operationally connected to the bolt and an obverse front side having a pair of transverse rebates for operational receipt of a first side of a cam driver; and, a cam driver operationally coupled to the cylinder and plug assembly wherein the cam driver has a first portion for selective rotary connection and synchronization with the rebates, whereby the locking means can be operated to permit rotation of the shell to any one of the four orthogonal operating positions so as to maintain orientation of pins in the plug in a desirably vertical position whether the bolt is in an up, down, left, and right extending position.
