VENTILATING SYSTEM FOR BAILWAY-CARRIAGES AND THE LIKE no. 900,614. Original application at March '1, 1905, stun following is a specification, reference being had to the drawings hereunto annexed and to the figures and reference-numerals marked thereonthat is to say The invention relates to a ventilating sys tem for railway carriages and the like'and is a divisional application from applicant's coendin application Serial No. 248,802, filed ar. 7t I905.

Accordin to the present invention fresh outer air w 'ch has assed through filtering devices is introduced near the roof thereof and the foul or 'vitiated air is extracted from the carriage through outlets also arranged in or near the said roof.

In the accompanying .drawings:-Figures 1 and 2 are respectively a longitudinal and a transverse section, the sections being taken on the lines A A and B-B of Fi s. 2 and 1 respectively of a railway. carriage ustrating the application thereto of the present invention and Figs. 3 and 4 are respectively similar views to Figs. 1 and 2.i llustrating a slight modification.

Referring to the drawings 1 is a receiver or collector into which fresh air from the outside of the railway carriage is forced by the resistance offered by the more or less quiescent air to the motion of the carriage and forated ends 2 and perforate said receiver consists of a casin having pertering partitions 3 and it is provided with a light swinging valve-4' pivotally mounted by its upper edge and which according to the direction of motion of the carriage assumes an 'angul flects the current of air downward into the bod of the receiver.

any suitab 'air filter 5 and the deflected current of alr'is T e body of the receiver 1 is provided with e filtering Tmedium constituting an com elled to pass through said filter as shown by t e arrows in Figs. 1 and 3 and which has the effect of arresting any particles of soot, coal and the like, carried 1n the air.

The body of the receiver 1 communicates with a passage or conduit extending over Specification of Letters Patent.

into the carriage at or ar. position on one side or the other of the receiver or collector '1 and consequently de-' Patented Oct. 6, 1908.

No. 258,802. Divided and this application filed October 27, 1908. Serial No. 340,891.

the entire length of the carriage exteriorly or it might be interiorly thereof as shown at Flgs. 3 and 4 and the current of filtered air carriage.

Hand regulating valves 11 are rovided between the conduit 6 and the receiver 1 to control the volume of atmospheric air ass ing to the interior ofthe carriage. ile fresh filtered air is thus introduced into the carriage, the foul air is sucked out therefrom through outlets 10 provided in the roof of the culiar ventilation efi'ect described in my ap- R lication hereinbefore referred to is insured.

he outlets1 10 may be so constructed in any well known manner that. by reason of the rapidpassage a suction like action is roduced and the removal of the foul air t us effected or if desired other well known means mi ht be rovided for extracting the foul air;

' t will e understood that the constructive details hereinbefore shown and described are merel given by way of..example and are capab e of variation without departing-from the spirit of the invention.

By, he means hereinbefore described the foul or' vitiated air is removed from a railduced 'thereinto without to any great extent mixing with the former while at the same time the incoming air is more or less heated by passing in close proximit to the outgoing warm but foul an and t us the atmoswholesome condition from a hygienic standpoint and by reason of the eculiar relative positions of the inlets an I outlets this is achieved without creating an appreciable draft.

Having now particularly described and ascertained the nature of t e said invention formed I declare that what I claim is:- I

1. In a ventilatin system for railway carriages and the like t e combination of a conduit extending longitudinally along the roof vfresh air is distributed'in the interior of the' carriage or adjacent thereto, so that the peway carriage or the like andfresh air is intro-- phere of the carriage is maintained in a.

and in what manner the same isto be perpasses into said conduit. Pipes or tubular -'of the carriage, conduits extending trans- 'ways connecting the longitudinal conduit vcrsely of the roof of the carriage, tubular with the transverse conduits, said conduits being open on the underside and there covered with filtering material, an air receiver on the exterior of the carriage conimunicating with the longitudinal conduit and provided with an air filter, a swinging valve in the receiver for deflecting the alr current toward the filter in either direction of motion of the carriage and air exhaust ways extending through the roof of the carriage as set forth.

2. In a ventilatin system for railway carriages and the like the combination of a conduit extending longitudinally along the roof of the carriage exteriorly thereof conduits 1 extending transversely of the roof of the carriage interiorly thereof, tubular ways connecting the longitudinal conduit with the transverse conduits, said conduits being open on the underside and there covered with filtering material, an air receiver upon the exterior of the carriage communicatin with the longitudinal conduit and provide with an air filter a swinging valve in the receiver for deflecting the air current toward the filter in either direction of motion of the carriage and air exhaust wa s extending through the sides immediate y below the roof of the carriage as set fortl SERGIUS TIMOCHOWITSCH.
