Indirect Acting Ceiling Fan In its action it bears a relation to the usual type of ceilingfan similar to that which the indirect lighting fixture bearsto the reflector type of fixture. Instead of allowing the draft. Application of the Indirect Fan to a Parlor Car;Placed Two Fixtures Apart the Fans Are to come direct from the fan to the passengers, the fan bladesare reversed, causing the current of air to be directed up-wards igainst the curved surface of a large disk which serves August, 191 RAILWAY MECHANICAL KNlilNKHR 429 as a deflector, redirecting the air downward again on all sidesof the fan; this air movement, however, is so gentle as not to cause any direct draft downward so that it strikes on theheads of the passengers. There is a constant movement of air upward immediatelybelow the fan and for an angle of about 45 degrees to thesides. Upon leaving the deflecting surface of the curved diskabove the fan blades, the motion of the air is almost hori-zontal in all directions. This latter movement striking thequarter deck of the cars or the sides of a room, is again de-flected downward. The result of this is that there is a gentleair motion which gives a decided effect of coolness in t
