VENTILATING CARS OIR YESSELS SPECIFICATION forming part of Letters Patent No. 590,515, dated September 21, 1897.
Application filed May 22, 1896.
To @ZZ whom, it may concern.-
Be it known that I, ALVIN M. CUSHING, residing at Springfield, in the county of Hampden and State of Massachusettshave invented a new and useful Car-Ventilator, of which the following is a specification.
This invention relates to improvements in ventilators for railway-cars, and more particularly to that class of ventilators which are actuated by a mechanical movement on the ouside of the car, propelled byla current of air produced when said car is in motion.
The obj ect of this invention is to provide a car-ventilator which can be regulated to admit any amount of fresh air desired and to put the same in circulation throughout the car.
Another object of this invention is to provide a car-ventilator which is exceedingly cheap in its construction and can be placed in any of the cars now in use.
With these objects in view my invention consists in the particular construction of the various parts and in the novel manner of combining or arranging said parts, all of which will be described hereinafter andpointed out in the claims.v
In the drawings forming a part of this speciication, Figure l is a sectional view taken on the line 2 2 of Fig. 3. Fig. 2 is a side elevation. Fig. 3 is a top plan View. Fig. 4 is a detail view.
Referring to the drawings, A represents the body of the car, having a shaft B extending through and journaled in its side wall near the top, as is shown at o, a in Fig. l, where I employ antifriction or ball bearings. The said shaft is provided with fan-wheels C and D, mounted, respectively, upon its interior and exterior ends, the exterior fan having its upper portion covered by a hood E, which may be of any suitable material and construction, to protect the same from storm and also prevent the current of air produced by the motion of the car from coming in contact with the upper arms or blades. Thus theair, havin g play only upon the lower blades, revolves the fan always in the same direction. Hence the interior fan is also revolved in the same direction, carrying the air toward the faces of the passengers, or always to the rear end of the car. 1
Directly beneath the fan-wheel D is a ventilator F, which may be of any suitable con- Serial No. 592,679. (No model.)
ventilator, and the fan C having arms or blades longer than those of the fan D will create a suction through the ventilator from the outside.
Beneath the interior fan I provide a shelf of sufficient length and breadth vto prevent the air from being forced down upon the heads of the passengers by the said fan.
On each side of the lower portion ofthe exterior fan I provide falsel panels or plates H H, secured tothe car at'their ends farthest from the fan by means of hinges b b, as most clearly shown in Fig. 2. These panels are so constructed and connected to the rods J, which extend through the wall of the car, that they can be operated by the same to shut off or turn on the current of air, thus regulating the fan at any speed desired.
It will thus be seen that I provide a ventilator which is simple in its construction and will proficiently perform all of its intended functions.
Having thus described my invention, what I claim asrnew, and desire to secure by Letters Patent, is`
l. In a car-ventilator the combination of a shaft extending through and journaled in a car-wall, said shaft carrying similar fanwheels mounted upon its interior and exterior ends, an air-inlet passage beneath the exterior fan, and a deflector-shelf beneath the interior fan, said interior fan having arms longer than those of the exterior fan, substantially as shown and described.
2. In a car-ventilator such as described, the combination of a shaft extending through and journaled in a car-wall, said shaft provided with similar fan-wheels mounted upon its interi or and exterior ends, the exterior fan having its upper portion covered by a hood E, and panels or plates H secured by hinges b on each side of the lower portion of the said fan, with rods for operating the same extending inside the car, substantially as shown and for the purpose set forth.
