Latch Lock, Key, and Catch

The Metropolitan Museum of Art

Latch lock, key, and catch by Joseph Bramah. The image shows a disassembled latch lock, key, and catch. The latch lock is at the top, with a long, thin piece extending from its right side. The latch lock has a curved piece on its left side and a jagged edge along its top. Three screws hold the latch lock together. Below the latch lock are two pieces: a small, rectangular piece with two holes and a curved cutout on its right side, and a key with a cylindrical base and a curved top. The key has a ribbed cylindrical base. The background is gray. The image is in black and white.
