UNITED I STATES PATENT OFFICE. A
JOHN LOUGHIN, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN VENTILATING CARS.. I
Specification forming part of Letters Patent'No. 183,405, dated October 17, 1876; application tiled September 27, 1876. V
To all whom it may concern Be it known that I, JOHN LOUGHIN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ventilating Cars; and Ido hereby 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figure l is a broken eleva-tion ci' an upper part of a car with my improvement applied.
- Fig. 2 is a broken section of the same. Fig.3
is an inverted plan of my invention.
My improvement has for its object to proi vide means for Ventilating a car by the provision of an air-chamber in the roof or below the latter, the bottom of said chamber constious perforations c c, through which the foul air arising from the inside of the car will pass, and be carried away by the lateral drafts through the open sides or Wire gauze. E E
represent ribs orv girders extending from the I side framings F or sills of the car, and serving to divide the chamber D into several apartments or passages, with a window or opening, G, at the end of each.
By means of this subdivision the drafts or air-currents may be better controlled and regulated than if said chamber were one unbroken space.
I prefer that the openings G should be on the sides, so as to cause the currents of air to pass laterally from the car, and avoid the inwardly and downwardly descending drafts incident to a front opening. Still, it' desired, openings may be made at H and H', either or both, corresponding openings being made in the girders E E for the passage ofthe air.
' What I' claim as my invention is- 1. A' car provided with a false ceiling, C, below the roof, forming an air-chamber, D, said ceiling being perforated or formed with openings c c for the passage of air, substantially as shown and described. 1 y
'2. The chamber D, having foraminated bottom, divided into separate compartments by the ribs or girders E E, and having lalso side openin gs G G, to permit the passage of lateral air-currents.
In testimony that I claim the foregoing I have hereunto set my hand this 20th day of
