Here's a screw-in plug. It's a Bryant, and is on a "Radioopticon" postcard projector. The stamped rating is 660W 250V.

They come from the era where you were more likely to find a light socket than an outlet.

From http://www.hubbell-wiring.com/History.asp

After viewing a janitor trying to clean behind some electrically-operated penny arcade games, Hubbell noted the tedious process required: that of disconnecting and reconnecting the post and wire connections in order to pull the equipment away from the wall. Hubbell's idea was to design a product with individual wires attached in the proper sequence and correct polarity, thus allowing the user to connect and disconnect to the power supply in the wall. His "separable plug and socket" design took shape and was submitted to the patent office in Washington, D.C. One of the most successful constructions of the patent is the duplex receptacle, still found everywhere that power is used.
