MEANS FOR VENTILATING CARS.
Specification of Letters Patent.
Patented Dec. 8, 1914.
Application filed March 14, 1912. Serial No. 683,682.
To all whom it may concern Be it known that I, CHARLES A. MooRn, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Means "for Ventilating Cars, of which the following is a specification.
My invention relates to improvements in ventilated cars for use in the transportation of perishable goods such as fruit, vegetables and other commodities.
The primary object of my invention is to provide a car which will supply freshen and expel vitiated air and at the same tlme keep the contents of the car cool and free from moisture.
Among further objects of my nvention is the construction of a car which 1s simple, inexpensive, strong and durable and WlllCll will provide a maximum lading space.
In the accompanying drawings forming part of this specification Figure 1 IS a plan of a car equipped with my invention; Fig. 2 is a longitudinal section taken upon the line AA, Fig. 1; Fig. 3 is a horizontal section immediately below the roof taken upon the line BB, Fig. 2; Fig. 4 is a horizontal section taken upon the line CC, Fig. 2; Fig. 5 is a section taken upon the line D D, Fig. 2, and Fig. 6 is a longitudinal vertical section of the car showing an alternative construction.
The car body illustrated by the drawings is of ordinary design being formed by outer inclosing walls, 2 representing the floor, 33 the ends, &d the sides and 5 the roof. These walls may be constructed of wood or metal or other suitable material mounted upon suitable frame supports in the usual manner. Inside these walls is a lining which is distanced from the outer walls of the car thus forming an air space in the walls through which a current of air is free to pass for the purpose of assisting in ventilating and preserving the lading in the car.
6 represents the lining above the floor, 77 represents the portions of the lining lying adjacent the ends of the car, 8 8 represent the portions of the lining lying adjacent each side wall of the car and 99 represent the portions of the lining lying adjacent the ceiling. The lining thus formed is closed except at that portion of the car in the ceiling which is positioned substantially midway between and isolated from the ends of the car, port openings 10 and 11 being formed through which air is admitted and expelled to and from the space between the lining and the outer inclosing walls.
In the roof of the car substantially midway between its ends and disposed near the opposite sides are two hatchways l2 and 13 which are respectively closed by doors 14; and 15 said doors being hinged to the roof of the car and adapted to be supported partly open and inclined up from the roof by means of hooks 16 or other suitable supporting and fastening devices. The angles of inclination of the two doors la and 15 are so that as the car moves in one direction, air will be directed down into the car and pass out of the opposite hatchway the door of which acting as a guard or cowl while the first dooris acting in the capacity of a scoop. A partition 25 diagonally across the ceiling between the hatchways serves as air guard. Part of the air entering by the hatchway 12 passes into the space in the wall and the remainder circulates in the lading chamber indicated by the arrows in Fig. 1. The portion of air entering the ventilating passage in the walls first passing longitudinally between the lining and the roof and circulates down through the passage in the end walls thence longitudinally through the floor, and up through the opposite end wall and out through the ceiling and opposite hatchway 13. The direction of this circulation as described is reversed when the car is moving in the opposite direction. The lining in the car is spaced from the outer walls and secured thereto through inter-positioned spacing strips which in a general way are disposed longitudinally in the ventilating space in the walls of the car. In the ceiling of the car the strips 17 converge toward the ends of the car. In the ends of the car the strips 18 converge downwardly their lower ends meeting the strips 19 in the floor which are disposed parallel throughout the length of the car, thus forming straight ventilating passages in the floor. In this manner there is a longitudinal circulation of air set up through the ceiling, ends and floor.
In addition to the ports 10 and 11 communicating with the ventilating passage in the ceiling of the car there are also formed two ports 20 inthe sides near the roof which are positioned between the ports 10 and 11. Each port 20 permits the ingress and egress of air down and up from a side wall between the nailing strips'21 which converge downwardly and trend in a general way slightly toward each end of the car. The passages formed by the converging strips 21 on each side of the car connect with passages formed by short nailing strips 22 near each side wall in the floor of the car, they in turn communicating through one of the spaces 23 extending throughout the length of the car in the floor adjacent the nailing strips 19. The strips 22 incline from the ends toward the middle of the car. This construction is similar on each side of the car and as a result the portion of the air admitted as indicated in Fig. 2 through the hatchway 12 passes down through a portion of each of the ports 20 through one end portion of each side wall of the car down through the portion of the floor adjacent the sides, thence longitudinally toward the opposite end of the car and up through the opposite end portions of the side walls and out through the remaining portion of the .same ports by which the air entered and finally egressing through the remaining hatchway 13. This circulation of air through the walls of the car and the lading contained therein removes vitiated airfrom the car and serves to evaporate moisture in the walls and to cool the contents of the car. Complete and thorough ventilation is thus provided which is advantageous.
It will be understood'that the car may be constructed with side entrances such as 2% which are adapted to be closed by ordinary doors 27 also that the car may be variously modified within the spirit of my invention.
In Fig. 6 is illustrated an alternative arrangement of nailing strips in the side walls of the car. These strips 26 are staggered, that is the strips are shorter than the distance longitudinally between the ceiling and the floor, the end of one strip being spaced from the floor while the ends of the two adjacent strips are spaced from the ceiling thus forming a continuous channel or a connectionbetween the passages which are formed bythese strips.
In accordance with the patent statutes 1 have described the principles of operation of my invention together with the apparatus which I now consider to represent the I best embodiment thereof but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
Having described myinvention, what- I downwardly at the rearward end of said chamber, forwardly over the floor of the car, upwardly'at the forward end of said chamber, back along the forward upper portion of said'chamber and finally expelled through said outlet to the outer atmosphere.
2. A car body inclosing a lading chamber, said body being provided with an air inlet and an air ou let located near opposite sides of the car in substantially median position between the ends of said body and a scoop placed over said inlet with its opening facing the forward end of the car, whereby air is forced by the forward movement of the car while it is advancing into and longitudinally along the upper portion of the rear end of the lading chamber, downwardly at the rear end of said chamber, forwardly over the floor of the'car, upwardly at the forward end of said chamber, backwardly along the forward upper portion of said chamber and finally expelled through said outlet to the outer atmosphere. l
3. A car body inclosing a lading chamber, said body being provided with an air inlet and an air outlet located substantially in median position between the ends of the body, said body being provided with an air passage extending longitudinally through the ceiling, walls and door and having a port opening at one end situated adjacent said inlet and a port opening at itsopposite end situated adjacent-said outlet, whereby air admitted through said inlet is forced by the movement of the car while it is advancing, longitudinally through the rear end portion of said ceiling, downwardly through the rearward end portion of said walls, forwardly through the floor of the car, upwardly through the forward end portion of said walls, back through the forward por tion of the ceiling, and finally expelled through said outlet. a
