dumbwaiter

A small elevator used to move food etc. from one floor of a building to another.

When writing he had a copyin machine: while he was a-writin he wouldn't suffer nobody to come in his room: had a dumb-waiter: when he wanted anything he had nothin to do but turn a crank and the dumb-waiter would bring him water or fruit on a plate or anything he wanted.

A table or set of trays on rollers used for serving food.

Sauces, wines, all the accessories we wanted, and all of the best, were given out by our host from his dumbwaiter; and when they had made the circuit of the table, he always put them back again.

A lazy Susan.
