Tl-IOMAS HENRY GARLAND, OF CHICAGO, ILLINOIS.

CAR-VENTILATOR.

Application filed November 15, 1904. Serial No. 232,825.

To all whom it may concern:

Be it known that I, THonAs HENRY GAR- LAND, a citizen of the United States, and a resident of Chicago, inthe county of Cook and State of Illinois, have invented a new and Improved Car-Ventilator, of which the following is a full, clear, and exact description.

My invention relates to a ventilator for cars.

The objects thereof are to provide means for securing efficient ventilation irrespective of the direction of motion of the car and at the same time to prevent the possibility of the entrance of 'rain, snow, cinders, 620., through the ventilator.

Further objects of the invention will appear in the course of the subjoined description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a transverse sectional view of a portion of a car, showing one form of my invention as applied thereto, a part of theventilator being shown in section. Fig. 2 is a sectional view on the curved line 2 2 of Fig. 1; and Fig. 3 is a transverse sectional view of a refrigerator-car, showing a form of my invention applied thereto.

Referring first to Figs. 1 and 2, an opening is made in the deck a of the car, as shown at a, and a main conductor 6 is placed along the roof (1 of the car with its inner end in said opening. The outer portion of the conductor is preferably curved to conform substantially to the shape of the roof and in its preferred form is made square in cross-section. The discharge end I) of the conductor is consequently located near theedge of the roof and faces downward. Therefore rain and snow cannot enter the conductor at this point. The conductor is preferably provided with a damper b at its inner end. A cowl c is located along the side of the deck and on the roof, with its axis parallel with the axis of the car and substantially perpendicular to the axis of the conductor 1). It is made flaring at its front end and is provided with a curved contracted end 0, leading into the side wall of the conductor b at the point 6 This contracted end is curved around into such position that its opening is directly in the center of the conductor 1) and points toward its outer end I).

Specification of Letters Patent.

tion in which the flared end of the cowl points, it will be obvious that air will be taken up by the cowl and discharged through the end 0 into the conductor b. This air will be forced through the conductor from the end of the cowl to the outer end I) of the conductor and will obviously take with it air from the other portion of the conductor, which can be supplied only by the entrance of air through the damper 6 It will be readily understood that this operation will result in the effective ventilation of the car and that the construction is of such a nature that foreign substances cannot enter the car. Although cinders can be blown into the cowl, they will be immediately discharged at the outer end of the conductor, and there will be no possibility of their being introduced into the car.

In order that the ventilator may work in both directions, it is made double and provided with a cowl pointing in each direction. These cowls may discharge into separate conductors, as indicated; but it is entirely within the scope of my invention to have them discharge into the same conductor.

It will be observed that a ventilator constructed upon the principle set forth above is very efficient in operation, is free from the objection of introducing foreign matters into the car, and is very simple in construction. Having no moving parts, it cannot easily become inoperative, and, being entirely station ary u on the car, it cannot readily be displace Fig. 3 illustrates one form of my invention as applied to refrigerator-cars. It could be applied in the same or a similar manner to fruit and vegetable cars. In this view the roof A is provided with a perforation A for the main conductor B of the ventilator, which slopes along the roof and has an outlet at B. A damper B is provided within the. car. A cowl C of similar structure to that shown in the other figures is located outside the car and connected with the conductor B, as described above.

Although I have illustrated and described particular embodiments of my invention, it will be obvious that the latter is not strictly limited to the details thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A ventilator having two cowls provided Supposing the car to travel in the direcwith flaring ends pointing in opposite direc- ICC tions and each being provided With a contracted curved end, and a pair of conductors into which said contracted ends lead, said conductors being curved downwardly at their outlet ends.

2. The combination with a car, of a ventilator having a conductor leading from the deck of the car and curving along the roof thereof, and a cowl extending longitudinally of the car and located on the roof thereof, said cowl having a contracted end entering the conductor and extending in an outward direction from the body of the cowl.

3. The combination with a car, of a ventilator having a conductor leading from its deck and curving along the roof of the car so
