The sections 28 and 29 extend through the wall of the head l and engage, respectively, stop-cooks 33 and 34, to which the supply-pipes 2 and 3 are connected.

The pipes 2 and 3 may supply water for the summer seasonto moisten and Cool the atmosphere in a room, or steam may be supplied through either of the pipes to warm the drum, moisten the air by the condensed steam, and also warm the air, or water may be supplied through one of the pipes 2 or 3 and steam through the other to effect the moistening of the air largely by water and use the steam as a heating medium. The supply of water and steam is regulated by the stopoocks 33 and 34C.

By this means the humidity and the temperature of the air in a room may be regulated and maintained to suit the purposes and exigenoies of the work being done in the room.

It is obvious that water or steam may be used alone and supplied through either of the pipes,2 or 3, if desired.
