SPECIFICATION forming part of Letters Patent No. 792,190, dated June 13, 1905. Application filed August 7, 1902. Serial No. 118,779.

To (all whom it may concern: sides of the car, and in the roof I employ a Beit known that I,I-IENRYSAMSETBAYER, suitable number of ventilating-caps 10, two of Charleston, in the county of Charleston, at each end of the roof 11 being indicated in State of South Carolina, have invented certhe preferred form of embodiment of my in- 5 tain new and useful Improvements in Railvention illustrated.

In practice both of the gates 22, one being located, as above specified, at each end of the car, are kept open; but under some conditions one may be kept open and the other closed, if preferred. By means of the open inlet or inlets a constant supply of fresh air to the ventilating-chamber is supplied, and from the ventilating-chamber it readily circulates through the false bottom 14 into the interior of the car, whence it finds egress through the iventilatingcaps 10 and also through the screen doors and windows, if they be open.

While the car is in motion, it necessarily takes in through the forward inlet-opening such an abundant supply of air as will produce a constant and considerable pressure upon the volume of air within the ventilating-chamber and drive it with force throughout the whole interior of the car. The airpressure so produced may be relied upon under ordinary conditions to promote effective circulation of air throughout the car, or, if preferred, for distributing circulation within the car a series of fans 26 within the ventilating-chamber may be employed for that purpose. The fans are preferably constructed with suitable arbors 27, which are mounted vertically within bearings provided for them in the floor 15 and false bottom 14, respectively. If fans be employed, two at each end of the car constitute a preferred number; but the fans at best constitute only auxiliary means for breaking up and distributing for circulation the currents of air which strike them, being preferably driven exclusively by the force of such air-currents as are derived within the car through the terminal air-inlet openings.

What I claim is- 1. A car-body having a false bottom defining a single ventilating-chamber extending unobstructedly from end to end and side to side of the car and communicating with the interior of the car and freely communieating at each end of the ends of the car with the external atmosphere.

2. The combination with a car-body provided with a false bottom defining underneath it within the car a ventilating-chamher, bounded only by said false bottom, the bottom, sides, and ends of the car, of parts provided with apertures in the opposite ends of the car respectively, each a erture being equal in height to the height 0' the ventilating-chamber and in width to the internal width of the car, and communicating .unobstructedly with the ventilating-chamber.

3. The combination with a ear-body provided with a false bottom defining a single ventilating-chamber extending unobstructedly from end to end, and from side to side of the car, of parts provided with apertures in the opposite ends of the car equal in height to the height of the ventilating-chamber, and communicating unobstructedly therewith, respectively.

4. The combination with a car-body provided with terminal apertures and side plates extending substantially from end to end within the car along its opposite sides, of a series of grids supported exclusively by said side plates, and constituting, as a means of defining an unobstructed ventilating-chamher, a false bottom.

5. The combination with a car-body provided with a false bottom defining a single ventilating-chamber extending from end to end and from side to side of the car, of parts provided with apertures in the opposite ends of the car communicating directly and unobstructedly with the ventilating-chamher,and a fan operatively located Within the ventilating-chamber and adapted to be driven by the forced draft, imparted by the motion of the car, through said chamber, for the purpose of breaking up and distributing said draft.

In testimony of all which I have hereunto subscribed my name.
