Hanging-Antique Vintage Cast Iron Light Fixture Repair Refurb

Description

Hanging-Antique Vintage Cast Iron Light Fixture Repair Refurb.
This heavy piece is intriguing. Hang up and it has three layers total. Pulleys are shown on top closest to ceiling. I don’t know how you adjust this. That piece says patented April of 1924. Then heavy middle and bottom piece has screws on the sides as if a glass went on it. The glass must be long broken. This piece has patented 1876 ( I think hard to read!). Needs a lot of cleaning. But definitely an old piece found in my Moms things.
