DEVICE FOR HEATING AND VENTILATING SUSPENDED HIGH SPEED RAILWAY CARS Filed Nov. 12, 1927 Patented (lot. 14, 1930 PATENT O-FFKTE FRANZKRUCKENBERG, OF HEIDELIBERG, GERMANY DEVIGE'FOR HEATING AND VEN'IILATING Application filed Hovembcr 12', 1927, Serial No.

This invention relates to suspended highspeed cars of the kind in which the passenger seats are arranged along the side walls of the car in such a manner that the passengers sit with their backs tothese walls, whereas between the two rows of seats a gangway is left in which passengers can stand. The present invention relates to means for heat ing and ventilating cars of this type, but in cont-radistinction to letting the fresh air rise fl-our the bottom to the top only between the rows '01 seats, I have provided means for in troducing fresh air also between the backs of the passengers and the side walls of the car in order to counteract the strong cooling of the air withinthe car by the side Walls; and, besides, means are provided for discharging the bad air from above the heads of the sitting passengers, as well as from above the heads 26 of the standing ones. The means for this latter purpose consist in two vertical longitudinal screenssuspended from those portions of the ceiling of the car which are located just over the heads of the passengers so as to separate the spaces above the heads of the sitting persons from the space above the heads oi the standing ones. Said screens consist oi an opaque material, that is to say, they are impermeable to light,- and the standing persons 30 cannot therefore look through them. There are windows in the side-walls over the heads of the sittingpersons and the said screens are located between the windows of the two side walls of the cars. Preventing the standing persons froinlooking through said windows is a precautionary means, in that the very qiiickly running carsassurne in curves correspondingly oblique positions, in consequence whereof the outer objects seem to be more or less oblique which will give rise to uneasiness, anxiety and nausea if t-hestanding persons can lookout of. the car. This is-by far less the case with the sitting persons because they look in the direction to the sky through the windows over the oppositely seated passengers.- Moreover the sitting persons can look only through a comparatively small portion of the opposite windows because the screens are in the direction of sight.

50. The invention is illustrated diagrammati- SUSPENDED HIGH-SPEED RAILWAY CARS why and by way of example on the accomp anying drawing on which is shown a vertical transverse section through a suspended highspeed railway car designed according to the invention. ()n the righthand side of the car is shown a standing person intending to sit down but having not yet begun to do so, and the same person is shown sitting on the bench or the like, and there are intermediate representations showing again the same person in various positions as occurring when sitting down. 2 denotes the vertical longitudinal screens mentioned in the preceding part of this specification, and 1 are the usual holding rods which are arranged as low as possible, preferably below the lower edges of the screens, as shown in the lelthand part of the figure. The rod 1 is located between the horizontal top planes of a sitting person of normal size and of a standing person of normal size, and its position with respect to the sitting persons is such that one does not contact with it when sitting down and when rising.

The. screens 2 may be rendered non-tran parent by advertisements, also by diapositives or the like used at the same time for decorating purposes. It might seem possible to omit the screens and make use of opaque windows, but I know from experience that this will makethe passengers uneasy and oppress them.

The wall of the ca" is, oi course, during the cold season considerably cooled by the outer air especially during running; this is even more true of the windows Zitrom which cin'rents of cold air iiow down onto the necks and the napes of the passeng s, as indicated on the rirghth'and side of the li urc. In order to do away with this disagrea-able and hurt fuldrawback, a screen (letthand side of the figure) is provided on the top of the back of the bench or the like, this screen, which is a protective screen. extending upwardly to the proximity of the windows 3 so that the air cooled by the same is kept of? the necks and the napes of the passengers. In fact,- however, the cold air does not pass away down: through the space between the screen and the back of the bench on the one side and the inner wall of the car on the other side down to the bottom of the car, but provision is made that a current of heated air passes upwards through the space between said inner wall and the opposite parts, as more fully dealt with hereinafter. The upper edge of the protective screen l may bear tubular lamps l1.

Below the floor of the passenger room is a space a, and above the ceiling of said room a space 5, and provision is made that the pres sure in the space a is always greater than that in the space Z), so that there arise air currents, as indicated by the arrows. The outer air enters into the space a through bottom apertures 5 which are provided with regulating means, and the bad air leaves the car through apertures 7 located in the top of the car shell at the spaces 6. The air flowing from the space a into the interior ofthe car is divided by vertical sheet-metal walls 8 (lefthand side of the figure) into two currents, the onewfiowing into the passenger room, the other flowing along the inner sides of the car shell upwardly to the windows 1 and further upwards through apertures 10 into the space 5. The air present in the passenger room escapes through apertures 9 also into the space 6, which communicates with the outer air through the apertures 7. The bent-oil lower portion of the sheet-metal I walls 8 may be hinged tothe upper part, that is to say, it may be movable and adjust able, and means may be provided for afiixingit in its adjusted position. 6 denotes heatmg bodies arranged in the space a.
