Murphy Company, New Kensington, Pa., a corporation of Pennsylvania Application August 13, 193s, serial No. 95,790 2s claims. (c1. 10s- 5.4)

l This invention relates to the hatchway construction of a metal car roof, particularly hatch constructions of the type wherein a metal hatch frame hasl an uninsulated upper portion disposed above the general level of the roof and closed by an uninsulated lid and a lower portion disposed below said level and forming a tapered seat for an insulated plug.

l The invention has for its principal object to simplify such a hatch construction bydispensing with the separate tapered heat insulated plug Aand the special tapered seat heretofore commonly required. Another object is to provide a preassembled heat insulated hatch frame and car- *line assembly adapted for application to the car as a complete unit. Other objects are simplicity, cheapness and durability of construction. The invention consists in the hatch construction and in the parts land in the combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawings which form part of this specification vand. wherein like symbols refer to like parts wherever they occur.

o Fig. 1 is a plan view of the end portion of a metal car roof provided with a hatch construction embodying my invention;

Fig. 2 is a vertical partial cross-section thereof on the line 2 2 in Fig. 1;

Fig. 3 is a vertical partial longitudinal section on the line 3-3 in Fig. 1;

Fig. 4 isan enlarged fragmentary section similar to Fig. 2 through one side of the hatch construction;

Fig. 5 is an enlarged fragmentary section similar to Fig. 3 through one side of the hatch construction; and Figs. 6, '7, 8 and 9 are views similar to Fig. 5 illustrating five modified forms of hatch construction.

The metal car roof illustrated in the accompanying drawings comprises end and intermediate roof sheets I and 2, respectively, that extend from side plate 3 to side plate 3 of the car with their eaves ends supported on and riveted or otherwise secured to the outstanding top flanges of eaves anglesy #,whose depending anges are riveted orotherwise rigidly secured to the upstanding inner side anges of said side plates. The '50 end and intermediate roof sheets are provided along their adjacentmargins' with upstanding flanges'i that are straddled by a seaml cap 6 that s is riveted or otherwise secured to said flanges and to thetop flanges of the eaves angles l. lAt the end of the car, the end sheet I is supported on straight', from top to bottom of said frame. Said the general level of the end roof sheet where it and riveted or otherwise secured to the outstanding top flange of an end angle 1, whose depending ange is riveted or otherwise secured to the outstanding top flange of a metal end plate la.

As shown in Fig. 1, the roof is provided with one 5 or more hatchways that lead downwardly into the interior of the car through the end roof sheet I and a framework located therebelow. Said framework comprises spaced parallel frame or carline members 8, which extend from side plate 10 to side plate of the car with their ends rigidly secured thereto by suitable brackets 9, and spaced parallel cross frame members I0 that are secured to and flush with the tops of said carlines and cooperate therewith to denne the hatchway open- 15 ing in said framework. As shown in Figs. 1 to 5, the carlines comprise metal angles disposed with one flange up and facing outwardly, and the A cross members I0 are in the form of flat plates that cooperate with said flanges to form a continuous supporting surface around the hatchway opening in said framework.

Mounted in the hatchway opening defined by the carlines 8 and cross plates Ill is a metal hatch frame having parallel side walls that extend frame extends downwardly through said opening with its carline engaging sides secured to the carlines preferably 4by welds I2 that extend along the lower edges of said carlines and with its two other sides 'secured to the cross plates I0 preferably by welds I3 that extend along the bottoms of said plates at the inner edges thereof. Said metal hatch frame also extends upwardly above is provided immediately above the carline members and cross members with an exterior downwardly opening hollow rim portion I4 formed by a flange that extends outwardly from the upper end of said frame and thence downwardly and outwardly at an angle thereto with its lower end located adjacent to the outer edges of said members.

The endif-roof sheet I is provided above the opening defined by the frame members 8 and I0 45 with a hatch opening of substantially the same size and shape as the rimv portion I4 of the metal hatch frame II, and anv upstanding ange` iiiA along the margin of said hatch opening `that bears against the outer face of the depending outer wall of said rim portion with its upper edge rigidlysecured thereto preferably by means of a weld I6 of added metal that extends continuously along the top edge of said ange. The metal hatch frame Il is closed by means of a members.

suitable lid or cover I1 that rests upon the top of the hollow rimportion I4' of said hatch frame and is provided with a suitable heat insulating material I8. The hollow rim portion I4 ofthe hatch frame is also provided with a iiller of any suitable heat insulating material I 9.

In the constructions illustrated in Figs. 6 and '7, the outer wall of the hollow rim portion 20 of the hatch frame is spaced from the outer edges of the carline members and cross-members to provide an opening 2| through which a loose, fibrous heat insulating material 22 may be inserted either before or after the hatch and carline assembly is applied to the car. In the constructhe hollow rim portion of the hatch frame are formed by a separate member 23 of angle-shaped section whose upper ange is secured by a weld to the upper end of the main body portion of saidhatch frame.

In the construction illustrated in Fig. 8, angle shaped carline members andcross members form the lower portion of the hatch frame; and the hollow upper rim portion thereof is formed by an inverted channel-shaped member 24 which rests on and is closed by the lateral top flanges of said The inner wall of the rim member 24 may be welded, as at 25, to the carline and cross members; and the outer wall of said rim is disposed parallel to said inner wall, instead of being serves to'prevent leakage therebetween and tor prevent movement of said sheet relative to the hatch frame.

material may be used as a ller for the hatch frame rim and held under compression thereby..

A rinrller of wood or rigid insulation material lmay also be used to stiffen and strengthen the hollow hatch frame rim.

The construction hereinbefore described has several advantages. The portion of the hatch frame located above the general roof level is insulated and is closed by an insulated cover, thereby materially reducing the transfer of heat through said portion and said cover into the interior of the hatch frame and thus dispensing with the separate tapered heat insulated plug and the tapered seat heretoforerequired therefor in the hatch frame. The carline and crossframe members of the combined carline assembly and hatch frame supports serve to stiifen' and strengthen the hatch frame rim and to retain the filler of insulation or other material therein. The complete carline and insulated hatch frame assembly may be assembled off the car and furnished for application to the car as a complete, preassembled unitary structure.
