FREDERICK B. TOWNSEND, OF HINSDALE, ILLINOIS, ASSIGNOR T0 01 CHAZY, NEW YORK.

VENTILATOR FOR CARS AND THE LIKE.

Specification of Letters Patent.

Patented Mar. 27, 1917.

Application filed May 10, 1915. SerialNo. 26,974.

To all whom it may concern:

Be it known that I, FREDERICK B. TOWN- SEND, a citizen of the United States, residing at Hinsdale, in the county of State of Illinois, have invented new and useful Improvement in Ventilators for Cars and the like, of which the following is a full, clear, concise, and exact de scription, reference being had to the accompanying drawings, forming a part of this specification.

his invention relates to improvements in ventilators for cars and the like.

The object of the invention is to provide a ventilator suitable for use on railway cars,

which is of simple construca certain from the interior of the car, and thus causing proper circulation of the air.

In the drawing forming a part of this specification, Figure 1 is an end view of a portion of the upper part of a car, showing my improved ventilator in connection there with, the ventilator being shown in vertical section. Fig. 2 is a side elevation of the improved ventilator. Fig. 3 is a horizontal sectional view taken substantially on the line 3-3 of Fig. 2, and showing the normal position of the parts when the car is at rest.

d Fig. 4 is a view similar to Fig. 3 illustrating the operation of the ventilator when the car is in motion, the arrows indicating the currents of air.

In said drawing I have shown my ventilator as applied to a car having a roof 10 and a sash deck 11, in which is located a ventilator opening 12 in the usual manner, it be ing understood that I have shown merely one ventilator, whereas in practice a number will be applied to each side of the deck. The ventilator, designated generally by the reference A, is secured to the car roof and deck opposite the opening 12, and, as shown, comprises a side wall 13, secured at its lower end to the roof 10, an upper horizontal wall 14, and a hipped top plate 15 adapted to shed rain and the like, as will be apparent. -Within the space thus formed, between the side member 13, top member 14 and the walls of the car, is located a combined deflector and exhaust 16, mounted to swing about a vertical axis formed by the pivots 17 17, the deflector being pivotally connected to a lower substantially horizontal plate 18 and Dupage and,

the top plate 14. The pivots 17 which are in the form of rivets also pass through upper and lower walls 19 and 20 of a member 21, which forms the exit duct for the air coming out through the opening 12.

the partitions 22 being oppositely arranged and at an angle to the direction of movement of the car. The deflector 16 is held in its normal central position by means of springs 2323 secured at thelr ends thereto and also to said member 21.

The operation is as follows: When the car is stationary, no action takes place, but when t e car moves, the walls ofit is deflected from the forward inclined partitions 22 and this portion of the deflectedair in conjunction with other air which 16, as viewed in Fig. 4, will against the action of th the outer edge of the forward wall 241 will the rear wall 26 of the deflector. As the currents of air rush past the deflector 16 in the position shown in Fig. 4, it will create a partial vacuum at the open end of the deflector 16, and thus create a draft, or current, from the interior of the car, as indicated by the arrows b. When the car comes to rest, the deflector 16 will return to its normal position, as shown in Fig. 3. It will also be apparent that the deflector 16 ma either way, depending upon the direction of movement of the car, and the action of creatcases. ment of the deflector 16, it is so constructed that the inner edges 2828 of its front and rear walls will engage the curved walls 27-27 of the exit duct opposite the opening 12, as shown in Fig. 4:. It will also be noted that the inclined partitions 22 of the fixed deflector in conjunction with walls 24: or 26 of the movable deflector are so arranged that they not only deflect the air as heretofore described, but prevent any dust or dirt which may be suspended in the air from passing around the inner edges 2828 or outer edges of the exhaust deflector 26, and

thus to the interior of the car, as might otherwise occur.

Various changes and modifications will suggest themselves to those skilled in the art, and I contemplate all such changes and modiiications as come within 'the scope of the claims appended hereto.

1 claim:

1. In a ventilator for cars and the like, the combination with a hood through which air is adapted to pass when the car is in motion and having a passage way communicating with the interior of the car, of a pivotally mounted deflector within said hood adapted to be actuated by currents of air when the car is in motion, said deflector surrounding the exit end of said passage way communicating with the interior of the car.

2. In a ventilator for cars and the like, the combination with a hood adapted to be secured to the roof of the car, said hood be ing provided with an opening extending lengthwise therothrough, a passageway adapted to communicate with the interior of the car and said opening through the hood, and a pivotally mounted, hollow deflector surrounding the outer end of said passageway and through which air is also adapted to pass from the interior of the car.

3. In a ventilator for cars and the like, the combination with a hood having an opening extending lengthwise therethrough and through which a current of air is adapted to be created when the car is in motion, said hood being provided with an air passageway extending substantially at right angles to said opening and adapted to communicate with the interior of the car, and a hollow deflector having portions thereof surrounding the outer end of said passageway,

said deflector being pivotally mounted and adapted to swing in either direction, dependent upon the direction of motion of the car.

4-. In a device of the character described, the combination'with a hood having a passageway extending longitudinally therethrough and a second passageway communicating with the first passageway and at right angles thereto, a pivotally mounted and spring controlled deflector surrounding the outer end of said second named passageway and through which air is adapted to be conducted from the interior of the car into the first named passageway, and relatively fixed inclined partitions at opposite ends of sai hood, whereby a current .of air passing through the first named passageway is adapted to engage andactuate said deflector from normal position to thereby cause an outwardly induced draft of air from the car.

In witness that I claim the foregoing I have hereunto subscribed my name this 18th day of April, 1915.
