Dumb Waiter Elevator Ideas

¶ The dumb waiter is most frequently used for the transmission of dishes and cookery between the kitchen and dining room, when, as it sometimes happens in large houses, these apartments are located in different stories.

¶ We here give a representation of the mode of working. A is the movable cupboard which passes up and down, containing the articles transmitted; this cupboard is balanced by the door C, by means of a cord E passing over a pulley B. The result of this mode of working is, that when the cupboard is down on the kitchen story, the aperture in the dining room is closed, and vice versa. D shows the groove on each side which prevents an unnecessary amount of rubbing and the consequent friction.
