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.
You put 3 drops of garlic, 3 drops of wilted wolfsbane, and 1 drop of mandrake root.
There are three in the Armory. Click on one to load the cannon, then get a lit candle from the fireplace to fire the cannon (three times). The first shot goes out the window, the second shot rolls into the Library, and the third shot shoots a hole in the armory ceiling. Use the ball that rolls into the library to wilt the wolfsbane: put it near the fire to get red hot, then pick up the poker from the fireplace to push it left into the dumbwaiter (hole in the wall). You can pull the lever in the lab to bring the hot cannonball out again.
