US Patent 7874189 Field-reversible cabinet latch lock

A four-way, field-reversible self-latching cabinet lock includes a cylinder and plug assembly shell that is rotatable with respect to a bolt housing cover for the lock. A locking device is provided to fix the cylinder and plug assembly shell in one of four orthogonal positions with respect to the bolt housing cover. The bolt housing cover is receivable by a bolt housing and conventional self-latching latch bolt. In this manner, pins in the cylinder and plug assembly may be retained in a desirable vertical position while a throw of the bolt can be adjusted to vertical, inverted, left-hand, and right-hand positions in the field without special tools or additional parts.
