well protected from cold weather. As refrigorator-cars are now constructed they may be used as winter cars by simply closi'ng the icehole doors and the side doors, or they-may be used as summer cars by charging the ice cool. e

"My'folding ventilator, when applied to the ice-hole doors of retrigeratoncarrg. will make these cars available a's ventilated cars, of a thoroughly practical character and will, en-

able the shipper to use the car on the same trip as a perfect vontilatedcar as well as an insulatedcar to protect the contents from damage by cold weather, or as a refrigerator car, when the icetanks are charged with ice, to protect the contents from heating, The folding wentilator will therefore berparticnlsrly-desirahle in the transportation of California oranges; &., during the winter-months, when it is necessary to use a car which will provide ventilation a portion of the distance through the. warm climate through which the car passes during the first few days of the iourney. Afteritreach'esthe cold climate, which is found a few hundred miles east of California, then my foldingveu- -tilator may be folded together and the icehole doors-securely closed to keep out the cold air, and from that time on the car is an insulated car and the coritents arethoronghly retooled from injury bycold weather.- Later fa the season when the weather .is warmer east, refrigerator-cars with my folding ventilator attachment may hej-nsed simply as ventilated cars to' destination., This -will .avoid the necessity of providing a different kind of a car to be used as a ventilated car in the spring of the year, and will ennhle the railroad transportation com nice to use their refrigerator cars from the eginning to the end of the season, which is not possible as they are now constructed, since there is no device whereby a thorough circulation of air can be provided:

formed being preferably closed on each side .by a wing formed by spiece of galvanized sheet-iron or other material, extending from the under side of the ice-hole door to the top 'of the car-on each side of the ice-hole. At the frontend of the car these side pieces or wings, together with the outside door of the ice-hole, form a scoop which catches the air tion and deflects and directs theair down into the par. 'Ih'e'i'ce-hnle door'whenadjustcd at this a.ng,"le,withont the side'wings,serves this otlice in a degree, but the addition of the side 'at the l'rontend of the car when it isinmo'f 8 g y wings greatly increases'its efliciency,-and the device as shown is completewithin itself, the side wings forming a desirable means for holding the door in itselevated position,-

and rear ends of the car are open with myventilator attached, the front ones to receive the air and force itinto the car, and the rear. onesjto permit an exit fol-the air after it has passed through the car. The front of the opening formed by the outside ice-hole door and thetwo side pieces shove referred to are screened, so that cinders and sparks cannot 1 {enter the ice-hole and cause damage to'the contents ofthe car by tire. This screen is fastened by hinges to the under face of the lid or-door of the ice-hole about ten inches back. from the front-edga-and when the ventilator is open the lower edge-of this screen door is fastened to a staple in the roof of the' car on theiontside of the ice-hole, which staple is also used tofasten the outside ice-hole door when the ice-hole is closed, Thecinders and sparks striking against the wire-screen will be arrested n-om entering the car andwill fall outside the ice-holes A feature of my'invention consists in having the side pieces, the combination of which I ls'.

the screen which extends across the mouth of the scoop is-also' fastened to the underface of the ice-hole door by hinges, so that when the ventilator is not used, the side pieces and the and screen can ,be folded downand fastened to the under face ofthe ice-hole door,

and the door can then be closed and the car thorcn insulated. The saiue device may.
