Claims. (Cl. 105375) The invention relates to insulated railway removements oftthe car from splashing the melted Y frigerator cars used to transport perishable comice against the stringers and through the foramimodities, such as Vegetables, fruits, berries, nous floor. meats, eggs, frozen fish; etc., and to maintain Another object is to provide means between the such commodities while in transit at a predeterslats inoan upper plane and the slats in a lower T5 mined range of temperature, thus necessitating plane to cause them to cooperate as compression the use of a cooling means in the summer and a and tension members respectively of beams, thus heating means in the winter. It has been found not only providing an anti-splash foraminousthat perishable commodities which have not been floor, but also providing a very strong foraminous l0 allowed to get .too cold (freeze) or too hot (bake) floor to support the lading in transit and also the have a high market value because they have a more concentrated load of a loaded truck or longer storage life.

Figs. 3, 4, 5 and 6 show modifications of .one 20 It is desirable to allow at least some of the form of my invention hereinafter described, melted ice to remain on the insulated floor 0f the wherein means are associated with the stringers car below the foraminous fioor to produce furto cover the spaces between adjacent slats adther insulation between the outside of the car jaceht the stringers to prevent splashing of meltand the air flues below the foraminous floor and ed ie throu h the foraminous floor. 25 also to further l h r u in The In the form of my invention illustrated the melted ice (water) has a temperature of about refrigerator car isprovided with a bulkhead 2 32 Fahrenheit when no salt is used a d as ow separating the refrigerant chamber 3 from the as 14 Fahrenheit when 25% salt is mixed with lading compartment 4.

A further object air is induced in the opposite direction because is to provide stringers for supporting the slats the air warmed by the heater rises and falls when and to provide means at the intersections of the cooled by the lading.
slats and stringers to prevent the longitudinal In the form of my invention shown in Figs. 3 55 to 6 inclusive the foraminous floor l8 comprises a plurality of spaced apart slats 25 supported by stringers 26 upon the insulated floor 6 of the car, which stringers are preferably positioned parallel to the direction of movement of the circulating air and the spaced apart slats 25 extend 'normally to the stringers 26. The refrigerating circulating air passes through the spaces 21 between the slats. Screws, bolts, nails or any other securing means may be used.
In the modification shown in Fig. 3 the channel shape member 30 is positionedbetween each stringer 26 and the slats 25 with the web 3| thereof resting upon the stringer 2B and the depending flanges 32 spaced from the stringer so that the water being splashed against the stringer will be caught by the depending flanges and not allowed to pass through the spaces 21 between the slats.
In the modification shown in Fig. 4 the members 36 are secured to each side of the stringer 25 which cover the spaces 21 between adjacent slats 25 to stop. the splashing water.
In the modification shown in Fig. short members 40 are secured to the string 26 in the spaces 27 between adjacent slats 25 which extend beyond both sides of the stringer to stop the splashing water. The upper surfaces 4| of these members are preferably sloped to provide a watershed.
In the modification shown in Fig. 6 the stringer 45 is preferably made of two metallic strips of metal secured together at 46 (preferably by welding) and formed to provide horizontally disposed portions 41 supporting the slats 25 and a substantially vertical portion 48 supporting the horizontal portions 41 upon the insulated floor 6 with the horizontal portions 41 having depending flanges 49 to stop splashing water. The arms of the vertical portion preferably diverge for stability. v
The accompanying drawing illustrates the preferred form of the invention, though it is to be understood that the invention is not limited'to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.
This is a division of my co-pending application Serial No. 167,771, filed October 7, 1937.
