REFRIGERATOR-CAR.

Application tiled February 23, 1912.

To all whom t may concern.'

Be it known that I, FRED PATEE, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Befrigc 'ator-Cars, of which the following is a specification,

This invention relates to improvements in refrigerator cars. The object of this invention is to provide an economical construction for cars, more especially for those cars designed for use as refrigerator cars. Another object of this invention is to provide a car with athermally insulated chamber in which perishable freight, or particularly food stuffs may be carried and maintained at a uniform temperature without the dan ger of rotting by being exposed to a circulation of moist air. Other objects will be apparent from the specification and appended claims, and from the drawings, in which- Figure 1 is a transverse section of a car embodying my improved Construction.

Fig. 2 is a fragmentary, vertical longitudinal section, the car being broken in two places to indicate the arrangement of the exhaust ventilators.

Fig. 3 is a transverse detail section showing the corner arrangement of the car.

Fig. 4 is a detail section along the line 41, 11 of Fig. 1.

Like numerals refer` to like elements throughout the drawings.

10 designates the siding forming the foundation of the ends and walls. This siding 10 is secured to the framework which is composed of the horizontal frame members or beams l1 and the vertical frame members or beams 11 running between the members 11.

Secured to the outside of the siding is the metal lathing 12, preferably of the sort formed with the ribs 12. Vhen this lathing is secured to the siding 10, as will be apparent, dead air spaces 13 are formed between the rib portions 12 and the outer surface of the siding 10. Furthermore, this use of the ribbed lathing is advantageous in securing the outside coating 14, preferably of asbestos, as shown in the drawing.

The roof, as shown in Figs. 1 and 2, of the drawings, is similarly constructed to the walls, with the exception that an outer protecting sheet 15 of corrugated metal may be laid on and secured to the coating of asbestes.

serial No. 679,460.

Interiorly of the siding 10 in the spaces between the

side beams

11 and 11 is placed a filler of thermally insulating material 16. For this filler I preferably use a composition of asbestos, ground cork and plaster of Paris, although plain asbestos may be used.

Upright metal I-beams 17 are arranged at spaced intervals in the sides and ends of the car. Located at the bottom of the car and having their ends adjacent the lower extremities of the uprights 17 are the cross beams 18. The uprights 17 have one flange secured by screw bolts or other means to the inner surfaces of the

frame members

11 and 11. The cross beams 18 may be secured at their extremities to the side beams 17 by rivets or other means, as indicated in the drawings.

Carried by the side beams 17 interiorly thereof are the inner walls 19 comprising on the outside a layer of asbestos 20 and on the inside a corrugated sheet of metal 21 by which is carried the coating of asbestos 20. An inner bottom 22 runs between the side walls 19 and is of the same construction.

Some distance below the inside of the ear is arranged a ioor 23 forming the roo-f of the packing chamber A which is inclosed by the side and end walls 19, top 23 and bottom 22. The top 23 is composed of a sheet of corrugated metal 21 sloping slightly downward on each side to the central portion 24. The corrugations of the sloping portions 24E run toward the central portion 211 which is formed with corrugations running longitudinally of the car, as shown in Fig. 1 of the drawings. Supported upon the corrugations of the corrugated members 24 are the longitudinal strips 25 of wood or other material. Below this member 211 and carried thereby is an insulating layer of asbestos 2G forming the top surface of the packing chamber A. The top of the car and the floor 23 and the side and end walls 19 together form an ice chamber B. Hatchways 26 communicate therewith through which ice may be supplied.

In one Side of the ice chamber B I provide an opening 27 at the upper portion thereof, while at the other side of the ice chamber I provide an opening 28 adjacent the floor of said chamber, for a purpose to be hereinafter described. It will be noticed that air spaces between the adjacent uprights 17 and cross beams 18 extend clear around the packing chamber. Through these air passa-ges or circuits a Vcurrent of cold air from the ice chamber is intended to travel. and the cross beams ll, ll are coa-ted with a coating of Wateiproofed asbestos 30, as shovvn in Fig. 4 of the draW- ings.Y This Will prevent absorption oi the moisture by the said coating and frame members. Ice supplied to the ice chamber B' will rest on the longitudinal strips25 and against Ithe longitudinal stripS5216- secu-red" to the 4sides and-endsofsaid--c-liainberto;

The use of the ribbed metal lathing l2 not only aids in securingthe outside coating of asbestos in place, but also provides dead air spaces 13 which greatly assist in the thermal insulation of the interior of the car.
