Bancroft, Dunn, N. 0., assignor, by mesne assignments, to Standard Railway Equipment Manufacturing Company, avcorpo ration of Delaware Application February 26, 1937, Serial No. 127,848 5 Claims. (0]. 62-17) This invention relates to refrigerator cars of the kind wherein the hatchways in the roof are de?ned by hatch frames that are supported by a framework that is sustained by the side plates 5 of the car. The principal object of the present invention is to utilize the hatch frames for sup porting overhead ice bunkers beneath the roof of the car, to provide for the ready removal and replacement of such bunkers without disturbing 10 the carlines. hatch frames, roof sheets or roof insulation, and to provide for simplicity and econ-_ omy of construction and compactness of de sign. The invention consists in the construction, combinations and arrangements of parts here inafter described and claimed. In the accompanying drawings, which form part of this speci?cation and wherein like symbols refer to like parts wherever they occur, 20 Fig. 1 is a plan view of a portion of a refrig erator car embodying my invention, parts being shown broken away in the region of one of the hatch sheets, ' roof sheets 2 disposed between adjacent hatch sheets. Each of the hatch sheets I has two hatchway. openings arranged one on each side of the ridge and provided with rigid hatch frames A for ad mitting ice or other cooling medium to overhead bunkers B located beneath said sheets. Located between each hatch sheet and‘ the bunkers lo cated therebelow is a framework comprising a pair of spaced parallel carline members l2 that extend from side plate to side plate with their 10 ends suitably secured thereto and .themselves connected by pairs of cross-frame members l3 that cooperate with said carline members to de ?ne openings beneathithe respective hatchway openings in said hatch sheet. Said carline mem 15 bers and cross-members preferably comprise oblique metal angles arranged with their sides converging downwardly. As shown in the drawings, each hatch frame comprises a metal frame having a relatively 20 _ located above the general _ Fig. 2 is a vertical longitudinal section on the level of the roof, a relatively narrow lower por Fig. 3 is a view similar to Fig. 1 on an enlarged carline members l2 and cross-members l3 and a shoulder l6 that rests ?atwise upon the tops of 25 said members. The wide upper portion Id of the metal hatch frame A has upwardly converging 25 line 2—2 of Fig. 1, scale, Fig. 4 is a' vertical transversesection through the roof at one of the hatchways on the line 4—4 30 of Fig. 1; and Fig. 5 is a view similar to Fig. 4 through one side of said hatch frame and the parts associated therewith. ' . tion I 5 ?tting within the opening de?ned by the side walls that terminate at the top of saidframe in an inwardly extending ?ange ii that con stitutes a seat for a hatch cover (not shown). The narrow lower portion l5 of said frame has downwardly converging side walls that conform to the downwardly converging sides of the car line members and cross-members and form a seat for a tapered hatch plug (not shown). The 35 ' hatch frame is preferably secured to the carlines Said roof sheets are provided along their adjacent margins with upstanding ?anges 5 that and the cross-members by welds l8 added con tinuously along the edges of said members; and the hatch sheet is preferably provided around the hatch opening therein with an upstanding 40 ?ange l9 that is secured to the exterior side face of the wide upper portion H of said hatch frame by a weld ‘JD/added continuously to the top edge of said ?ange. As shown in the drawings, 45 the relatively ‘ narrow, downwardly converging lower portion l5 of the hatch frame A extends below the support ing framework therefor where it has a continuous the upstanding ?ange of an outstanding ?ange 2| formed by oblique metal The roof sheets I,’ hereinafter re-_ angles 22 that are rigidly secured to said frame longitudinally 5 at each end thereof and with one or more of the 50 by means of welds 23 added continuously along the top and bottom edges of said angles. The ?ange 2| extends outwardly substantially flush with the lower edge of the hatch frame and is 55 2,120,345 2 perforated to receive bolts 24 for suspending the voverhead bunkers B therefrom. These overhead bunkers are preferably arranged in alinement opposite ends in communication with said hatch frames, and bolts for detachably seeming said bunker to the outstanding ?anges of the respec sides of the ridge, being spaced apart at the ridge tive hatch frame around the top openings in said‘ bunker. and the bunkers on the same side of the ridge of hatchways spaced apart longitudinally of the longitudinally of the car in two rows on opposite 2. A refrigerator car roof having a plurality being spaced apart at their adjacent ends. Each bunker preferably extends continuously between adjacent hatchways with its ends located below 10 and provided with top openings that register with car on opposite sides of the ridge, hatch frames for the respective hatchways, and bunkers lo cated beneath said roof and extending longi 10 tudinally thereof on opposite sides of the ridge, the lower ends of the respective hatch frames. These openings are defined by a frame 25 of metal the bunkers on each side of the ridge extending between and in communication with and sus tained by two adjacent hatch frames on said side 15 of said ridge. 3. A refrigerator car roof having a plurality angles disposed with one ?ange down and the other facing inwardly and secured ?atwise to the 15 underside of the hatch frame ?anges 2| by the bolts 2i. The bunkers are provided with sheet metal top, bottom and side walls and are rein forced at their corners by other angle irons 26. If desired, the metal walls of the bunker may be 20 stiffened and strengthened by corrugations or other reinforcing-members (not shown). The roof is provided above the bunkers with a relatively rigid insulating board lining or cell-' ing 21 that is sustained by wooden nailing strips 25 28 secured in the angles of the carline members and also by supporting strips 29 and 30 along the sides and ends, respectively, of the car. The space between the ceiling and the roof sheets of hatchways spaced apart longitudinally of the car on opposite sides of the ridge with the hatch ways on one side of the ridge disposed opposite the hatchways on the other side thereof, hatch 20 frames for the respective hatchways, bunkers located beneath said roof and extending longi tudinally thereof on opposite sides of the ridge, the bunkers on each side of the ridge extending between and in communication with and sus 25 tained by two adjacent hatch frames on said side of said ridge, and a plurality of frames ex tending transversely of the car from side to side thereof above the level of said bunkers, said is ?lled with a suitable ?brous insulation 34. 30 The hereinbefore described construction has several advantages. The bunkers are suspended from the hatch frames independently and with out the aid of the roof sheets. The bunkers may be readily removed and replaced without disturb 35 ing the hatch frame, the hatch frame support ing framework, the roof sheets or the roof in sulation, access being had to the securing bolts of said bunkers through the hatchways. Each bunker may be made as long as desired and may be provided with as many hatchways as are nec essary to insure uniform loading of the bunker. By arranging the hatch frame supporting frame work above the bunkers in the space provided for the roof insulation, the headroom of the car may be increased without increasing the outside height thereof. What I claim is: 1. A refrigerator car roof having a plurality of hatch frames therein provided below said roof with outstanding flanges, a bunker located be neath said roof and having top openings in its frames being spaced apart longitudinally of the 30 . car and each frame supporting a hatch frame on one side of the ridge and the corresponding hatch frame on the other side thereof. 4. A refrigerator car roof having a rigid metal hatch frame therein, a bunker located beneath 35 said roof and having an opening in its top com municating with the lower end of said hatch frame, and means for detachably suspending said bunker from said lower end of said hatch frame, said means constituting the sole supporting 40 means for said bunker. 5. A refrigerator car roof having a plurality of rigid metal hatch frames therein, a bunker lo cated beneath said roof and having openings in its top communicating with the lower ends of the respectve hatch frames, and means for de tachably securing said bunker to said hatch frames around the openings in the top of said bunker, said means constituting the only sup port for said bunker. ‘ ALFRED G.
