VENTILATING SYSTEM.

T 0 all whom it may concern:

Be it known that I, AMELIA LOUISE WER- l NEH, a citizen of the United States, and a resident of Cincinnati, county of Hamilton, and State of Ohio, have invented a new and useful Improvement in Ventilating Systems, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a ventilating system adapted especially for use on street cars, and has for its object the introduction, without injurious drafts, of a constant supply of fresh air equally distributed throughout the car, and the removal of the foul air therefrom; these objects to be accomplished by a simple and inexpensive construction readily adaptable to a car of any ordinary design.

In the drawings: Figure l is a horizontal longitudinal section, with the foul air outlet in plan. Fig. 2 is a vertical longitudinal section. Fig. 3 is a section showing the foul air outlet.

The numeral 1 indicates the fresh air duct, which is constructed at the top of the front vestibule of the car, and may be of any suitable shape adapted thereto. To the inner, and smaller, end of said duct 1, tubes 2 and 3 are attached, as shown in Fig. l. The tube 2 extends around not less than three sides of the interior of the car, near the ceiling thereof; said tube 2 has openings at suitably spaced along its under side. Attached to the interior of said tube, above the openings 4, are depressed flanges, or other current deflectors, 5, each of said flanges being in a relation of slightly increased depression to the one immediately preceding it in se quence from the duct 1. Completely enveloping the tube 2, and large enough to create a chamber between it and said tube 2, is the tube 6, said tube 6 having openings 7 suitably spaced along its upper side. The interior of the tube 6 has no connection with the air duct, save through the openings lin the tube 2. The ends of the tubes 2 and 6 farthest from the duct 1 are closed by a cap 8 as shown. The tube 8 leads from the air duct 1 to a pipe 9 connecting with the interior of the car at a point near the ceiling and extending vertically through the roof thereof; said pipe 9 carries on its upper extremity a ventilating cowl l0.

Specification of Letters Patent.

Application filed July 23, 1910.

In order to regulate the supply of air a Patented Sept. 2'7, 1910.

Serial No. 573,469.

' damper 11 of ordinary design is mounted in the duct 1.

From the foregoing the operation of my system will be apparent. The fresh air will flow from the duct through the tubes 2 and From the tube 2 it will be distributed through the openings 4, and by the aid of the flanges 5, equally throughout the chamber between the tubes 2 and 6; from tube 6 it will pass through the openings 7 upwardly into, and be equally distributed by the many small currents throughout, the body of the car, descending from the points of entrance in accordance with natural law. The current passing through the tube 3 will create a draft and suction through the pipe 9, which suction will be further heightened by the cowl 10, and the foul air, having risen in accordance with natural law, will be drawn into the pipe and discharged from the body of the car.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A ventilating system comprising a fresh air duct, a tube leading from said duct, said. tube having a series of openings at suitable intervals along one of its sides, and a series of air deflectors in said tube opposed to said openings, each of said deflectors being in a relation of increased depression to those preceding it in sequence from said fresh air duct.

2. A ventilating system comprising a fresh air duct, a fresh air tube leading from said duct, said tube having a series of openings at suitable intervals along one of its sides, and an enveloping tube adapted to create an air chamber around said fresh air tube and to deflect the currents of air received therefrom, said enveloping tube having a series of openings through which the fresh air is released into the body of the car after having been so deflected, and said fresh air tube and said enveloping tube having their ends farthest from said fresh air duct closed.

8. A ventilating system comprising a fresh air duct, a fresh air tube leading from said duct, said tube having a series of openings at suitable intervals along one of its sides, a series of air deflectors in said fresh air tube opposed to said openings, each of said deflectors being in a relation of increased depression to those preceding it in sequence from said fresh air duct, and an enveloping tube adapted to create an air chamber around said fresh air tube and to deflect the currents of air received therefrom, said enveloping tube having a series of openings through which the fresh air is released into the body of the car after having been so deflected, and said fresh air tube and said enveloping tube having their ends farthest from said fresh air duct closed.

4:. A ventilating system comprising a fresh air duct, a tube leading from said duct, said tube having a series of openings at suitable intervals along one of its sides, and a series of air deflectors in said tube opposed to said openings, each of said deflectors being in a relation of increased depression to those preceding it in sequence from said fresh air duct, a pipe adaptedto remove the foul air, and a tube leading from said fresh air duct to said pipe to produce a suction therein.

5. A ventilating system comprising a fresh air duct, a fresh air tube leading from said duct, said tube having a series of openings at suitable intervals along one of its sides, an enveloping tube adapted to create an air chamber around said fresh air tube and to deflect the currents of air received therefrom, said enveloping tube having a series of openings through which the fresh air is released into the body of the car after having been so deflected, and said fresh air tube and said enveloping tube having their ends farthest from said fresh air duct closed,

a pipe adapted to remove the foul air, and a tube leading from said fresh air duct to said pipe to produce a suction therein.

6. A ventilating system comprising a fresh air duct, a fresh air tube leading from said duct said tube having a series of open ings at suitable intervals along one of its sides, a series of air deflectors in said fresh air tube opposed to said openings, each of said deflectors being in a relation of increased depression to those preceding it in sequence from said fresh air duct, an enveloping tube adapted to create an air chamber around said fresh air tube and to deflect the currents of air received therefrom, said enveloping tube having a series of openings through which the fresh air is released into the body of the car after having been so deflected, and said fresh air tube and said enveloping tube having their ends farthest from said fresh air duct closed, a pipe adapted to remove the foul air, and a tube leading from said fresh air duct to said pipe to produce a suction therein.
