Most of these fascinating silverplated pieces were made between 1877 and 1900 in America. These had different types of mechanical gadgets for opening the cover. Many of which were patented. They took the form of chains, gears, rods, and handles which, when pulled or pushed, automatically opened the cover or drawer.
These items were called "Jewel Caskets". After 1900, the boxes got much simpler and were just called jewelry boxes.
