SPECIFICATION forming part of Letters Patent No. 598,371, dated February 1, 1898.

Application filed April 27, 1897. Serial No. 634,084. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN M. HAUFF, of Allegheny, in the county of Allegheny and State of Pennsylvania,haveinvented a new and useful Improvement in Ventilators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a partial side elevation of a railway passenger-coach having a clearstory provided with my improved ventilator. Fig. 2 is a partial sectional view of the same. Figs. 3 and 4 are longitudinal vertical sections showing two different forms of my improved ventilator; and Figs. 5 and 6 are vertical sections of Figs. 3 and 4, respectively.

My invention relates to ventilators, and more especially to those employed upon railway passenger-cars, and is designed to provide an improved device of this character which, while allowing entrance and exit of air, will prevent the entry of smoke and cinders into the car.

In the drawings, 2 represents the roof of the clearstory of a car, and-3 the side portion of the same. On the roof of the clearstory I show the simplest form of my ventilator, this being shown in larger detail in Figs. 4 and 6. It consists of a hollow box-like case having a longitudinally-curved cover 4, which projects laterally beyond the sides 5 5, narrow arc-shaped openings being provided between the cover and the upper edges of the sides. The cover is preferably held in place by strips 6, secured to the side and to the cover or deflector 4, and the ends of the deflector 4 are preferably bent inwardly, so as to leave a very narrow space between the ends of the bottom 8 of the ventilator and the end portions of the deflector, as shown at a. From the bottom or base portion of the ventilator the tube 7 leads to the interior of the car.

In operation-as the. car moves in either direction the air striking against the curved cover or deflector will pass over the same and create a suction, which draws the air from the ventilator out through the narrow openings at the sides. The deflector projecting beyond the sides prevents entry of dust or cinders contained in the current of air striking the Ventilator, and the foul air is thus drawn out of the car without entry of objectionable impurities.

In placing a ventilator upon the side of the clearstory or upon any part of the side portion of the car I employ the form shown in Figs. 3 and 5, in which the bottom 8 is curved downwardly and is closed, except fora small hole 9,through which any impurities may pass out of the ventilator. In this case the tube 7 leads from the side of the ventilator in through the side of the car or clearstory, and it is evident that the action will be the same as before, the current of air striking and being deflected by the curved cover, so as to draw out the air from the upper part of the car, while the current of air itself passing over the ventilator is prevented from entering it.

The advantages of my invention will be apparent to those skilled in the art, since a cheap, simple, and effective device is provided by which ventilation of a car or other structure may be attained without the entry of cinders or objectionable matter.

Many changes in the exact shape of the ventilator may be made in the scope of my claims.

I claim 1. In a ventilator a closed hollow box provided with closed sides having curved upper edges, and a curved convex cover-plate forming the top of the box and extending laterally beyond its sides, the only substantial openings in said box to theouter air consisting in curved narrow slots between the upper edges of the sides and the cover.

2. In a ventilator the combination with a box having a closed bottom and a tube leading therefrom into the car or apartment, said box having closed sides provided with curved upper edges, and a convex cover-plate extending laterally beyond its sides and supported slightly above their upper edges, leaving narrow curved slots which form the only substantial openings to the outer air.

3. In a ventilator, the combination with a box having a closed bottom and closed sides having curved upper edges, of a longitudinally-convex deflector supported above the sides and extending laterally beyond them, the deflector being carried upon supports secured to the sides.

In testimony whereofI have hereunto set my hand.
