What are Dumbwaiters?

A smaller elevator used to carry and hold food. They are often connected to two or a few different floors in a building. They usually operate from a kitchen when they are installed in retirement homes. schools, and hospitals. They are now known as lazy Susans and serving trays but the term "Dumbwaiter" seems to originate from the United States in the 1840's. An inventor from New York City named George W. Cannon invented the mechanical dumbwaiter, and in 1887 he filed for the patent. 

Dumbwaiters used to be manually controlled with ropes on pulleys. But electric motors were added to dumbwaiters in the 1920s.They are able to carry weights from 45kg up to 450kg. These lifts were very popular in the houses of the rich and privileged in London. Codes such as fireproof walls and self-closing doors were also sometimes ment to be followed in the early 20th century. Not only was it used to deliver food in order to reduce the number of servants in the house but it was also used by maids to deliver laundry. 

Dumbwaiters are named so because they can act as silent servants, as the old term for someone that could not speak was "dumb". 

Types of dumbwaiter lifts

Dumbwaiters that are motorized require only a minimal amount of maintenance and initial installation. It can have up to six stops added as well as travel up to 80 feet vertically. They save a great deal of time when the need to transport goods arises. They are also environmentally friendlier than conventional lifts as they use less energy. Because the need to do manual heavy lifting is cut out, it decreases the chance of injury.
