FAN FO R RAI LWAY-CARS.

SPECIFICATIONfor-ming part of Letters Patent No. 461,712, dated October 20, 1891.

Application filed June 29, 1891.

To wZZ whom it may concern..-

Be it known that I, EMMET PERKINS PUT- NAM, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Fans for Railway-Cars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvementin a fan for railway-cars, and its novelty will be fully understood from the following description and claim, when taken in connection with the annexed drawings; and the objects of my invention are to provide a fan for sleeping and other cars upon a railway train. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a cross-section of sleeping-car. Fig. 2 is a front view of ventilator. Fig. 3 is a side view of fan. Fig. t is a sectional side View of car.

Similar letters and numerals refer to similar parts throughout the several views.

In the drawings, A refers to the car; B, an axle, upon which is placed a pulley C, which connects with pulley D by means of belt 1, pulley D receiving its movement from O, which is attached to axle.

E is a pulley which is connected to pulley F by means of belt 2, pulley being upon a shaft 0, which runs lengthwise of the car.

Gisapulley placed on shaft of fan II. Said pulley G is connected to shaft 0 by means of a belt 3.

K is a hanger for fan.

L are air-chambers attached on side of sleeping-car berths, and in which there are ventilators N for each berth. These air-chambers L are constructed of rubber or heavy canvas, or of any material that will permit them to be folded. By placing pulley E on a shaft in Serial No. 397,948- (No model.)

the manner shown, all effect from vibration of car is prevented, and I obtain a steadier movement for my fans.

In practice I place belt 1 over face of pulley O and D before train is started, and as the axle of car is rotated this places in motion pulleys D, E, F, and G, thus causing fans H to be rotated, and causing a current of air to be driven into chambers L, and enablingpassengers who occupy berths M to be supplied with a current of air by simply opening ventilator N, and closing same when it is not desired to admit air, thus enabling passengers on a sleeping-car to rest comfortably at night and in a manner heretofore unknown. During the day the air-chambers L can be renioved and laid away with the bedding of the sleeping-car, and the fans H continue to rotate during the day in the sleeping-cars when the train is moving, and may also be used advantageously in an ordinary passenger-car.

Having described my invention and the manner in which the same is or may be carriedinto effect,lwould sayin conclusion that I do not limit myself to the precise details shown in illustration, as the same may be varied to some extent; but

What I claim,and desire to secure by Lettors Patent, is

The combination, with a sleeping-car, the fans having their shafts connected to the roof of the car at intervals in the length thereof, and

a suitable means for rotating said fans, of the air-chambers formed from flexible material attached to the sleeping-berths and having their upper ends flared or enlarged, and ventilating-openings between the air-chambers and the respective berths, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two Witnesses. EMMET P. PUTNAM. Witnesses: MICHE DE. COURSEY, PERoY D. PARKS.
