A LUXURY FOR THE BRIDGE ENTHUSIAST. Hammond's electro-mechanical bridge table was introduced in 1932, just in time for Chicago's 1933 Century of Progress exhibition. 
The Hammond Company and its inventor/owner Laurens Hammond were known primarily for its production of clocks and organs, notably the B3. A chess and bridge aficionado, Hammond invented the electric bridge table wherein a card deck is placed in the deck tray. Pushing in this tray activates an electric motor by opening a strategically placed switch on the metal frame. As the mechanism turns (clockwise) an arm bearing a rubber "thumb" swings around. When it nears the tray containing the cards, it lowers and pulls the top card up a ramp onto the circular track. A second arm hooks the card and carries it around the track.

The mechanism in the center "decides" which of the four hands will get the card. 
A serrated wheel has notches cut to three depths in 52 positions. The depth of the notch determines the destination hand. Each full deal cycle requires 53 rotations of the mechanism, so each deal is begun from a different point in the pattern. Hammond called this the "robot."
