My invention relates more particularly to an improvement in refrigerator car construction and more especially to the method of construction `whereby a steel frame car may 6 be provided with suitable insulation and thereby utilized as a refrigerator car.

The invention has for its object the provision of a construction wherein'a portion of the means emplo ed for holding the in- 10 sulation in place will also constitute means functioning as nailing strips to which the inside lining of the car may be secured; while the various bolts employed, whereby the steel posts or exterior braces are secured in place, are so arranged in the' walls of the car as to permit a complete sealing of the bolt-heads and at the same time provide dead air space insulation. v

The invention also has for its object a construction wherein the various wall elements consisting of cleats or sub-posts and girths are so arranged as to securely hold the pliable insulating material 1n place against sa ging; the ent-1re Wall construction, inclu ing the roof and the floor belng such that a complete insulating blanket 1s provided which affords continuous insula- `tion at the side lates, namelyI at the sides and the ends of t e car as wel as across the to 'of the car.

llhe objects and advantages of m lnvention will be more clearly comprehen ed from the detailed description of the accompanying drawings, wherein- Figure 1 is a vertical sectional viewof a ortion of a car, with intermediate portions liroken away, illustrating my improved construction.

Fi 'ure 2 is a cross sectional view taken on 40 thelme 2-2 of Figure-1 looking in the direc-tion of the arrows.

My invention contemplates the utilization of a steel frame car as a vrefrigerator car which, as exem liiied in the drawings, comprises a suitab e floor construction of subtimbers with floor-boards as indicated at 10 all supported in the usual manner by the car-sills, one of which is shown at 11, to

which the steel posts or Z-bar braces shown at 12, as well as the corner plates or posts 13, are intended to be secured at their lower ends, while the upper ends thereof are secured to the angle members 14. The angle members D14 have the steel side plates 15 secured thereto, which, in turn, overlap the outer side of the outside sheathing 16; the sheathingl 16 being preferably chamfered to receive t e side p ates as shown at 17. The outside sheathing 16, as clearly shown in Figure 1, extends to and rests on the side sills of the' car underframe and the entirek inner side of the outer sheathing is covered with suitable pliable insulating material 18 which is preferably arran ed in double thickness or layers and preerably. of continuous sheets as shown. The insulating material 18 is also preferably placed intermediate of the paper lining, indicated at 19, arranged along the inner side of the outer sheathing 16 and the inner sheathing or lining 2O extending from the upper edge of the topmost sheathing and the upper edge of an upper'wooden girth 21 which is secured in place by the bolts which extend through the steel side plate and sheathing.

The car frame or wall construction also comprises a suitable number of wooden cleats or sub-posts 22 preferably arranged at .equal distances apart and disposed from top to bottom intermediate of the outer sheathing 16 and the inside sheathing or lining 20 and bolted at top and bottom, with the bolt heads being preferably arranged as hereinafter descrlbed.

The wooden sub-posts 22 are formed to receive the horizontally disposed wooden girths 21 therebetween; the girths being arranged at different horizontal levels and spaced apart as shown in Figure 1.

The girths are securedin place by bolts, as at 23, which extend throu h the steel posts and outer ,sheathin T e heads of the bolts 23 are referab y countersunk inthe girths 21; an before the bolts are put into place, the countersink is filled with a. sealing compound, as for exam le an asphalt roduct, a portion whereof isl rawn into the bolt-holes when'the .bolts are inserted, thus completely sealing the bolt-holes. The counter sinking of the bolts is done to such an extent that, when the bolts are in place the heads, embedded in the sealing compound, a

dead air space will be provided between the vbolt.heads and the paper lining 19, as more and the heads thereof insertedin and sealed l with a suitable non-conducting compound ing and-arranged vto provide a dead air-space at the inner or head end of the bolts, a non- .heat conducting connection between the car exterior and its interior is provided.

The various girths and the sub-posts are utilized and arranged to hold the pliable insulating material, preferably hair -felt, in

place and prevents the material from shiftor from sagging toward the bottom;

while at the same time the girths and the osts also constitute nailing stripsfor the inside paper lining and the inner sheathmg. p v

The side wall is provided with a meatrail at 25, which is suitably bolted to the .sub-posts and extends through the inner sheathing of the car. I

A The liable insulating material,-in the form op continuous sheets,ispreferably arranged in at least two layers as shown and the sheets continued from the :tloor-where it is arranged between the sub-floor 26 and the main floor l-upward along the side and end walls of the car and entirely across the top of the car, thus providing a complete blanket of insulating material extend- 4 lng through all parts of the car to the doorposts on opposite sides of the door-opening;`

' the sheet or one layer being preferably arranged that its meeting ends are off-set from or disposed atk a different point from the meeting'edges of the other sheet 'as shown at 27 in Figure 1.

As'shown in Figure 1, the insulating sheets i i continue from the side wall about the juncture of the side the insulation arranged between ,the blind vceiling 28 and the inner or mam ceiling 29.

wall and car ceiling, with The ceiling structure comprises the carline 30,-which is secured to of'inverted channel formation,-in which a wooden sub-carline 31 is secured by means of'bolts. The bolts which secure the subcarline in place also constitute the means for holding suitable Wooden cleats 32 in lace; the cleats being disposed beneath the b ceiling 28 and firmly hold the insulatlind ing material in proper place. These cleats also constitute nailing strips for the main ceiling boards 29. I also prefer to provide the juncture between the sides and the top of the car with a wooden fillet, as at 33 in vFigure 1, to provide a tight juncture or corner.

As a result of my invention, a steel frame car may be utilized as a refrigerator car, which is completely enveloped by a blanket -sheathing, ing intermediate'of the blind ceiling and the or layer and supported 'by thev angle members 14, and is preferably of suitable insulating material and wherein all bolts which extend from the car exterior are also completely sealed, with -the result that a [very eilicient, thoroughly insulated refrigerator car is provided.

I have shown what I believe to be a simple embodiment of theinvention, which has been described in terms employed merely as terms of description and not as terms of limitation, as structural modifications are possible and may be made without, however, departing from the spirit of my invention.
