UNITED STATES ALBERT SCHNEIDER, OF PORTLAND, OREGON.

VENTILATING DEVICE.

Application filed June 2, 1924. Serial Ito. 717,441.

To all whom it may concern.

Be it known that I, ALBERT SCHNEIDER, a citizen of the United States of America, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Ventilating Devices, of which the following is a specification.

This invention relates to improvements in ventilating systems and has particular reference to a system for ventilating railroad cars in which passengers are to be carried, and refers to the same subject matter as that contained in applicants abandoned application, Serial Number 513,257, of November7th, 1921.

The principal object is to provide means 'whereby fresh air maybe caused to circulate through the car, and to further provide means for regulating the air to be circulated in accordance with the wishes of the occupant adjacent the ventilator.

A still further object is to provide means whereby all foreign substances will be filtered from the air, thereby eliminating many of the disadvantages which are com' mon in train ventilation, such as cinders and insects.

- Another object is to produce a device of this character which is simple in construction, cheap to manufacture and one which may be applied tostandard cars of all types without materially altering the construction of the cars, or without weakening the frame thereof.

Other objects and advantages will be ap-' parent during the course of the followmg description.

In the accompanying drawings form ng a part of this specification and in which l ke numerals are employed to designate like parts throughoutthe same,

Fig. l is a fragmentary view of a Pullman car having my device applied thereto and shown partly in cross section,

. Fig. 2 is a vertical cross section of a car having my ventilating system applied thereto.

Fig. 3 is a perspective view showing the preferred form of intake casting,

Fig. 4 is a detail view showin the intake castinginstalled in a car an shown incross section,

Figs. 5 and 6 are modified forms of the intake casting shown in cross sect1on,

Fig. 7 is a perspective -view showing the arrangement of the filtering and draft con- 7 trolling means.

In the accompanying drawings wherein bafiles slant downwardly and inwardly, as

best shown in Fig. 4.

An lntake'port 13 is formed in the bottom ofthe chamber, while an ont let port 14 is formed adjacent. the upper extremity of the chamber, which other port is adapted todis' charge-alr into a ventilating ipe 16. This pipe extends through the We of the car 5 and terminates at a point flush with the inner wall and slightly below the window casing.

It is of course obvious that the device might be placed anywhere in the car With- (t ut departing from the spirit of the invenion.

A flange 17 is formed 11 on the casting through the medium of wii ich flange the device as'a whole is secured to the exterior wall of the car 5. I

In the modified forms shown in Figs. 5 and tithe construction is identical, except that in Fig. 5 the pipe 16 is an independent casting, andin Fig. 6 the pipe 16 terminates at a point flush with the interior of V the car wall instead of projecting into the car ashort distance as shown in Fig. 4.

A filter constructed in accordance with Fig. 7 is employed with the device.

It will be noted that the filter consists of aframe 27 which is adapted to hold a screen 28 against which a filter 29 is placed. This screen and filter are in turn held in the frame 27 by a plate 31 having a sliding shutter 32, which shutter enables the passenger to regulate the amount of air drawn a through the device.

In order to induce-circulation and to make my system complete I provide an air outlet 33 adjacent the end of the upper portion ofthe car, within which air outlet I place an exhaust fan 34 which is adapted to bev driven by an electric motor from the electric system of the car. It is of course understood that the nm located in the air outlet at the rear of the car is the only one in motion unless the car is standing still, in which event the fan located at each end of the car may be driven if desired. In Fig. 2 it will be noted that I have placed the ventilating device in such a position that fresh air will be caused to enter the upper berths of a car as Well as the lower, and I have further provided openings 36 in the berth cover so that the air can freely circulate through the bedding and through the car.

It Will thus be seen that I have provided a very simple and efficient means for properly ventilating the interior of passenger coaches.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, 1 claim In a train ventilating device, a casting adapted to be secured to the outer wall of a car, a pipe extending through the wall in said car and communicating with said easting, said casting having an inlet port formed in the bottom thereof, a plurality of down- \vai'dly and inwardly inclined bafiles positioned in said casting, means for filtering the air passing through said device, said means comprising a screen, a filter pad in contact with said screen, means for holding said screen and said pad to said device, and means for regulating the rate of flow of air through said device, for the purpose specified.

In testimony whereof I afiix my signature.

ALBERT SCHNEIDER.
