Application December s1. lssa'sernl N0. 116,858 ' 'z om. (o1. ss-m‘ y 'I‘he present invention relates to ventilators suitable louvres I8 in its sides to permit air to adapted for installation in the roofs of enclosed .passlnto the interior of the car. The bOtÈQm' vehicles, especially freight cars and refrigerator » I9 of the housing slopes downwardly toward the end wall l and is provided with a drain pipe 2l i The objects of the invention are to provides. to carry oiï any rain water which may enter4 ....„lentilator which can beclosed tightly to pre-ß through the hatch. Water is thus prevented vent loss of heat from the interior of the car; from reaching the cargo space of the car, while ' which can be opened to varying degrees to per-_ air is freely admitted thereto through the cars. . . . f _ .Y mit the entrance of more or less outside air under louvres I8. ` ` - ` Angle irons 2| are secured to the bottom of 0 the influence of the wind created by the car's movement; which can be folded back upon the the plug lo along its side edges and are provided car roof when wide open to prevent increasing with spaced loops 22 which serve as hinge sup the total eiïective height of the car; and which - ports for side .wings or'deflectors 23 provided 10 will permit ventilation, and at the same time ' along their upper edges with holes through 5“ prevent rain water from entering the cargo space of the car, and prevent pilfering', of the Ycargo Ntherefrom. Other objects and advantages of the `invention will become apparent from the follow 4 ing description which should be read with the ;0 understanding that the form„construction and arrangement oi the several parts may be varied, within the scope of the appendedV claims, with :5 which said loops 22 are passed. The wings 23, which are approximately triangular in shape, hang vertically at the sides of the hatch i when vthe cover is 'in Ventilating open position. as shown in Fig.-1, and shut out ‘cross currents of' air which would interfere with the main air cur 20 rent entering the ventilator. ‘A transverse de ilecting plate 24, positioned betwe the wings Aout departing from the spirit of the invention. 23, is hinged to the' upper rear edge o the nousReference will be made to the accompanying- ` ing I1, as shown at 25, and is provided at its -upper edge with lugs adapted >to slide in chan drawing, invwhich » -Fig. 1 is a longitudinal section of the ventilator nels 26 formed in the angle irons 2|. The plate f' 2‘4 assists in deñecting the air into the housing as installed in the roof of an insulated car. Fig._ 2 is a transverse section taken' from the right,'as viewed in Fig. 1 and showing the yen 10 tilator closed. . In the drawing, the reference numeral 3 desig-. nates the roof of a car and 4 is one end wall thereof. A hatch 5 is formed in the roof and'is surrounded by the usual raised combing i. A 5 metal plate 1 is hinged at 8 to a bracket >9 se cured to one side of the combing 6. A plug Il I1, and prevents loss ‘of air through the space . between the rear edge of the plug I0 and the vcombing B. . When it is desired to open the ventilator wide, ' and to eliminate its wind catching features. the cover 1 is swung back to lie ñat on the roof 3 of the car. .In this position,” which is not shown in the drawing, the wings 23 fold down lfiat upon 35 the plug I0, as will be readily understood from of insulating material is secured to the under-` their -shape and hinge mountings. A chain 21 side of the plate or cover 1,'and when the latter extends across between the lower portions of said is closed„as shown in Fig. 2, said plug III tits A Wings _and causes them automatically to fold 0 tightly within the hatch s andeljrectively seals . down when the cover 1 is thrown back ilat upon - the opening against loss of heat from the in terior of the car. _ Avyoke or loop Il extends from the free edge ofthe cover 1 and slides freely over a lever I2,4 5 the latter being hinged to the roof of the car at I3, and provided with a plurality. of spaced holes I4 which register with corresponding slots I5 in the sides of the loop Il. A hook I6 is adapt- '. l) ed to engage the slots I5 and any one of the holes I4 to hold the cover 1 in various open pomtions. When _the cover is closed, the lever I2 lies down closely thereover, as shown in dotted lines in the'r‘oof, the weight of said chain pu°‘ing>said wings inwardly. The lugs of the transverse deiiector 24 slide out Ñfrom the open rear. ends of the channels ,26 4when thecover is thrown back, allowing said deflector to drop down‘and rest within the rear portion oi.' the housing I1. ’ It will be seen from the foregoing description that my device provides an adjustable ventilator adapted to catch the wind caused by the motion of the car and to conduct-the air impelled by such wind into the interior’ of the car. At the y A metal box or housing~ I1 is secured inside same time, the housing I1 prevents rain from reaching the cargo space in the car„and prevents pilfering of the cargo through the _hatch when _the car under the hatch 5, and is provided with the ventilator ls'open.
