- n. A door-lock designed to be fastened to the surface of the door.
Sorry, no etymologies found.
I am sure that a good, well-designed door with a simple box-lock and hinges would be much less costly than velvet hangings.
Yours is a box-lock; the blackguard will have hid in the works at night, and taken the lock off, left his writing, and then screwed the lock on again: that is nothing to any Hillsborough hand.
