The Ticker-Scope was a device for displaying tickertape to a room full of people.
The cabinet incorporated a large magnifying glass, a light bulb, and two mirrors to enlarge and illuminate the tape.
A stock ticker base was attached below the cabinet, with it's gears rising through hole at the bottom. A clockwork mechanism pulled the tape across the bottom board of the Ticker Scope in real time. The tape then exited the opposite side for "normal" viewing, if so desired.
The TickerScope was invented in 1917 by John Hartford Chidester, and a patent was granted in 1920. As you can see in the drawing below, it was originally designed for the NYQ Ticker, which was prominent at that time, though quickly being phased out.
The patent drawings included an iron clamp to hold the ticker in place.
