11 Claims.

My invention relates to metal car roofs of the type wherein an insulating lining is suspended on the metal portion of the roof. The principal object of the invention is to devise means which will support the insulating lining in proper relationito the metal sheets, which will take up a minimum of head room in the car, which will provide for the easy application and replacement of the lining, which may be applied without weakening any portion of the roof structure and which will not extend appreciably below the insulating lining. The invention consists principally in welding stud bolts in notches provided therefor in the lower edges of reinforcing plates secured in the roof seams, said stud bolts having nuts which support inverted channel members with lateral flanges on which the lining is supported. It also consists in the combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawings wherein like reference numerals refer to like parts wherever they occur,

j'Fig. 10 is'a; perspective view of one of the slotted hanger bolts; and

Fig. 11 is a fragmentar'yside view of the assembled hanger plate and the slotted hanger bolt.

The construction illustrated in the drawings comprises metal roof sheets I which extend from side plate 2 to side plate 2 of the car. These roof sheets have their side marginal portions raised or offset upwardly to form panels 3 at a somewhat higher level than the adjacent body (Cl. rose-5.2)

portions of the roof sheets. At the outer margins of such panels are upstanding flanges 4. Between each upstanding flange of one roof sheet and the adjacent flange of the next roof sheet is a metal plate 5 which extends downwardly below 5 the raised panels of the adjacent sheets. A metal seam cap 5 of inverted U-shape with horizontal flanges 1 straddles the upstanding flanges of adjacent sheets and the interposed suspension or hanger plate 5 between them and all are firmly 10 secured together by horizontal rivets 8.

The lower margin of the suspension plate 5 has rectangular notches 9 therein of suitable width and depth to receive stud bolts i0 and afford adequate bearing surface for welding said 15 stud bolts to said suspension member in vertical alinement therewith. As illustrated in Figs.

4 and 5, the notch 9 is of greater width than the diameter of the stud bolt l0 and the weld metal I! fills the spaces between the sides of said bolt and the adjacent edges of the suspension plate 5. Preferably also the end face of the stud bolt is welded, as at I 5a, to the sides of said plate at the bottom of said notch. As an alternative construction, the bolt may snugly fit the notch and be welded directly thereto by any suitable method of welding.

Each of the stud bolts i0 is provided with a nut 52 that works on the thread at the lower end thereof. These nuts support an inverted channel-shaped member l3 which has holes for the stud bolts IE! to extend through and which has horizontal marginal flanges 14 which serve as ledges or supports for an insulating ceiling or lining. Preferably, this lining is in the form of sections I5 of ply wood of suitable length for its ends to rest on the flanges M of adjacent supporting strips I3. Resting on the end portions of said insulating sections are strips "5 of wood or other suitable material that extend crosswise of the car and are of substantially the same width as the marginal panels 3 of the roof sheets. By this arrangement, the nuts l2 are supported by the hanger bolts l0 and themselves support the inverted channel-shaped members l3 whose flanges I4, in turn, support the insulating lining l5'which, in turn, supports the spacing members l6. Thus, when the nuts l2 are tightened, the spacing members 5 are clamped against the under surfaces of the raised panels 3 of the metal roof sheets and serve to space the insulating lining l5 at such distance below the main body portions of said sheets as is predetermined by the thickness of said spacing members.

In the modified construction illustrated in Sheet 2 of the drawings, the lower margin of the seam plate SA has a relatively shallow notch 9A therein; and the stud bolt lilA has its upper end notched or slotted, as at HUB, so as to straddle said plate just above the notch therein. The stud bolt is secured to the plate by welds MB. This arrangement enables the notchin the seam plate to be made shallower or entirely dispensed with; and it also prevents the stud bolt from twisting and straining the securing weld therefor.

The overall width of the inverted channel shaped lining supporting strip l3A of the modifled construction is less than the overall width of the strip l3 shown in Fig. 3; and the width of the inverted channel of the strip HA is reduced between hanger bolts. By this arrangement lining supporting strip I3A may be pressed from a relatively narrow blank without decreasing the Width of the nut receiving portion of the channel and without reducing the width of the lining supporting flanges MA thereof except at points opposite said nut receiving portions.

The foregoing construction is very simple and strong and its application does not cause any weakening of the seam reinforcing plate. It enables the insulating lining to be applied and replaced wholly or in part with great facility. It enables the depth of the insulating air space between the lining and the metal roof sheets to be varied by substituting spacing members of one thickness for those of another. As the stud bolt nuts are located inside of the inverted channels, they add very little or nothing at all to the overall depth of the lining and thus do not decrease the head room of the car.

What I claim is:

1. A car roof comprising roof sheets connected along their adjacent margins by seams, plates embodied in said seams and having vertically disposed lower marginal portions, members depending from and permanently secured to said vertically disposed lower marginal portions of said plates, and a lining located beneath said roof sheets and sustained by said members.
