The Ceiling-Post Rack: Hang the Wash Where the Air Is Warm
Indoors in winter, a rack of wet washing takes up floor space and dries slowly at knee height.
Ezra B. Gildersleeve of New York received US 181,164, dated 15 August 1876 (filed 30 June 1876), for a clothes-drier whose post of sliding pieces is raised until a capped end presses on the ceiling and is locked by a ratchet and pawl. The rack is then raised on it, holding the clothes "above the heads of the occupants of the apartment, and where the air is most likely to be heated".
This rung works out how much faster warm air near the ceiling can take up water, then measures the temperature and humidity at the floor and near the ceiling of a room and dries two towels at each.

The embedded blueprint heats a room with an iron stove. Warm air rises from it and collects under the ceiling, where Gildersleeve hangs the wash.

"The piece E is then moved upward until the cap I comes in contact with the ceiling, when the pawl-piece is applied and locked, the pieces D and E forming a secure vertical support."
"The rack and clothes are thus held out of danger of being soiled above the heads of the occupants of the apartment, and where the air is most likely to be heated."

Measure the room and dry two towels
In a heated room, read the thermometer and hygrometer at knee height, then near the ceiling. Compare them with the notebook.
Wet two identical towels and wring them the same. Weigh each. Hang one on the drying rack at knee height and one on a line near the ceiling, strung between two screws in the wall. Weigh both every hour and note how much water each has lost.

History and honest limits
History and honest limits
**Ezra B. Gildersleeve** of New York filed US 181,164 on 30 June 1876; it is dated 15 August 1876. The post stands on a revolving pedestal, so the rack can be turned.
**Honest limits.** The notebook assumes the same vapour content throughout the room and takes the cloth at air temperature. A wet cloth is cooler than the air, and air movement matters too. The temperatures and humidity are examples. Your towel weighings are the measurement.
