One thousand revolutions per minute, I deem 'suiicient to' produce the desired current-of air within the car, when it is travellmg at the rate ot' twenty miles per hour.

By this arrangement, the air which circulates inside of the car, to produce ventilation, is free from all particles ot smoke and dust, or` other substances, and a To vall whom it may concern.- y I Be it known that I, OLIVER SLAGLE, of London,k Madison county, State of" Ohio, have invented a certain new, and useful Improvement in Car-Ventilators; `and Ido hereby declare the following to be a suipertains, toniake anduse it, reference being had to the accompanying drawings, making partof this soecification.

- My invention consists of an apparatus for creating a strong current of air through railroad-cars, &c., for` ventilation, or 4the prevention of the accumulation of dust in the cars, which apparatus 'is set forcibly in` the wind-wheel upon the outside of the car;

Any ordinary double-cylinder blower may be used instead ,of the fan B. A'

`The shield E prevents the air fi'on acting upon but one side of' the wheel E, and it carries au air-collector, G, which collects the air and directs it into the wheel.

Sufficient distance is left between the shield, at the give the latter the requisite velocity. l

My invention further 'consists of certain reversible devices, for collecting and discharging the air, which adapt the apparatus for motion of the train iu either direction. r

In the accompanying drawings- Figure 1 is 'a perspective view, partly in section, which exhibits the arrangement and construction of my devices.

Figure 2 is a plan of the apparatus, with the aircollector adjusted for the running of the train in one direction. f

Figure 3 is a sectional plan of the same, with the collector adjusted for the opposite direction. v

a represents a perspective view of the winged wheel E, and case F, aud fan B, with case A attached to the top of any ordinary car-roof; the wind-wheel E being upon the outside of the car, and the fan B and case A beinglocated within the car;the apetures O being in the sides ofthe fan-case A. Thewingedwheel E, on the top ofthe roof', is conreception and escape of the an'. The shield is pivoted at f, and is adapted to parin figs. 2 and 3, for the purpose of adapting the'apof the train.y n The plate G is reversed by handle I, which extends man, o1 passengers.

I claim herein as new, and of my inventionthe car-roof, driven by an outside current ot' air, produced by the locomotion of the car, coming in contact with the same, in combination with the horizon- -tal fan B, located n pon a suitable shaft, geared tothe vertical shaft of' the wind-wheel E, when said blower is located within the dome ofthe car, substantially as pose of driving the same, and the gearing may ,be constructed so that the fan has a greater velocity than The wheel E is driven by the air, which is admitted at one side oi' the same, when the train is under ino tion, and this is sufficient, when properly geared, to give the fan one thousand revolutions per minute.

The wind-wheel E is propelled by an outside current'of air, produced by the locomotion of the car, and should not be admitted into the car, as tine particles of dust and smoke are inevitably admitted with all currents of air that would thus pass into the cer.
