A dumbwaiter is a small freight elevator or lift intended to carry food. Dumbwaiters found within modern structures, including both commercial, public and private buildings, are often connected between multiple floors. When installed in restaurants, schools, hospitals, retirement homes or in private homes, the lifts generally terminate in a kitchen. Limited Preview, ''

Description

A simple dumbwaiter is a movable frame in a shaft, dropped by a rope on a pulley, guided by rails; most dumbwaiters have a shaft, cart, and capacity smaller than those of passenger elevators, usually 45 to 450 kg (100 to 992 lbs.) Before electric motors were added in the 1920s, dumbwaiters were controlled manually by ropes on pulleys. Early 20th-century building codes sometimes required fireproof dumbwaiter walls and self-closing fireproof doors and mention features such as buttons to control movement between floors and locks on doors preventing them from opening unless the cart is stopped at that floor. Dumbwaiter lifts in London were extremely popular in the houses of the rich and privileged. Maids would use them to deliver laundry to the laundry room from different rooms in the house. This obviated carrying dirty washing through the house, saving time and preventing injury. A legal complaint about a Manhattan restaurant's dumbwaiter in 1915, which also mentions that food orders are shouted up and down the shaft, describes its operation and limitations as follows:

here is... great play between the cart of the dumb-waiter and the guides on which it runs, with the result that the running of the cart is accompanied by a loud noise. The rope which operates the cart of the dumb-waiter runs in a wheel with a very shallow groove, so that the rope is liable to and does at times slip off. ... The cart has no shock absorbers at the top, so that when it strikes the top of the shaft or wheel there is a loud report. ... e ropes of the dumb-waiter strike such wall at frequent intervals with a loud report. ... e dumb-waiter is often negligently operated, by running it faster than necessary, and by letting it go down with a sudden fall.

More recent dumbwaiters can be more sophisticated, using electric motors, automatic control systems, and custom freight containers of other kinds of elevators. Recently constructed book lifts in libraries and mail or other freight transports in office towers may be larger than many dumbwaiters in public restaurants and private homes, supporting loads as heavy as 450 kg (1000 lbs).

Regulations governing construction and operation

Building codes have regulated the construction and operation of dumbwaiters in parts of North America since the 19th century. Modern dumbwaiters in the United States and Canada must comply with American Society of Mechanical Engineers (ASME) codes and, therefore, have features similar to those of passenger elevators.See
