antique time switch, steampunk early machine industrial, Anderson - Boston

Very old electric time switch with nice old label from Albert and J M Anderson Mfg. of Boston Mass, with the instructions and schematics pasted inside the 12" long metal housing cover. It's marked with patent numbers from 1904 and 1910.

This is very heavy, and looks good inside and out, though we haven't plugged it in or done anything to test it. We're not really sure what it's original intended purpose was, though it should be possible to research this through the patent office files with the patent numbers, I think.
