The lever with the red knob moves the dumbwaiter in the Library, but it is not necessary to use it. The other red-knob lever is in the laboratory.

The only time the dumbwaiter will work is when you have a red-hot cannonball to put into it (part of the armory activities). Roll the loose cannonball near the fireplace. When it is hot, pick up the fireplace Poker and roll the cannonball into the dumbwaiter. Throw the lever in the laboratory to release the cannonball there.
