Bauer, Huntingdon Valley, Pa., assignor to The Budd Company, Philadelphia, Pa., a corporation of Pennsylvania Filed July 1, 1968, Ser. No. 741,776 Int. Cl. B61d 17/12; E04d N28 US. Cl. 52-46 4 Claims ABSTRACT OF THE DISCLOSURE A roof construction for a vehicle having longitudinal sheathing members supported on transversely disposed carlins having aligned notches. The sheathing members are deformed along their edges to constitute stringer portions which are received in the aligned notches. The deformed stringer portion of one sheathing member is overlapped by an edge portion of a next adjacent sheathing member.

One type of roof construction which has previously been used for such purposes includes longitudinally spaced carlins connected at their ends by through-running Z-shaped beam members to enable securement of the roof to the side walls of the vehicles. A longitudinally running roof covering is afl'ixed to the top surfaces of the carlins. In addition longitudinally extending stringer members are secured to the downwardly extending web portions of the transversely disposed carlins. A disadvantage of such construction is that the stringers are discontinuous and are not through-running. Consequently joints are required at the ends of each stringer portion thereby accounting for a great multiplicity of joints.

It is an object of this invention therefore to provide an improved roof construction which avoids one or more of the disadvantages of the prior art constructions and which eliminates labor in putting the same together.

It is another object of this invention to provide a roof construction which is less costly and which eliminates the possibility of leaks as a result of cutting down on the number of joints required.

For a better understanding of the present invention together with other and further objects thereof reference is had to the following description taken in connection with the accompanying drawings and its scope will be pointed out in the appended claims.

In the drawings FIG. 1 is a side elevational view of a portion of an enclosed railway vehicle embodying the invention;

FIG. 2 is a partial enlarged section taken along the line 22 of the FIG. 1;

FIG. 3 is a sectional view taken along the lines 33 of FIG. 2;

FIG. 4 is a sectional view similar to that shown in FIG. 2 but illustrating a modified form of the invention;

FIG. 5 is a sectional view taken along the lines 55 of FIG. 3 illustrating the carlin.

A vehicle 10, in the present instance, an enclosed railway car adapted for suburban passenger usage, has a roof 11, side wall 12 and a floor 13.

The roof assembly includes longitudinally spaced carlins 15 connected at their side ends by Z-shaped roof sill members 16. The side wall includes vertical posts 17, outer covering skin 18 and an inner top plate 19 capped at the upper end by the aforementioned Z sill member 16.

As seen in FIG. 2 the ends of the carlins are supported on the top surface 21 of the roof sill member 16 and are secured in place by gusset members 23. The latter gusset includes a horizontally disposed flange 24 which rests on the top surface 21 of the sill member and in "ice addition a side flange 25 engages its vertical web. The carlins 15 may also be of Z section and support a plurality of generally flat sheathing members 26, first, 27, second and 28, third on their upper flange surfaces.

As seen in FIG. 2 the carlins 15 include a plurality of cut-outs 29, spaced along the upper peripheral edged surface of the top flange of the carlins. Adjacently disposed carlins 15 along the longitudinal axis of roof include like spaced cut- outs 29, 30. It is noted in addition that the upper edge of the longitudinal skin sheathing member 26 includes a hat shaped deformation in cross section, 31, disposed along its upper longitudinal edge. The like spaced cut-outs 29 of adjacently spaced carlins receive the inverted hat deformation 31 of the first longitudinal sheathing member 26. The second sheathing member 27 spaced above sheathing member 26 includes a lower edge portion 32 which overlaps the longitudinal stringer deformation 31 of sheathing member 26. The portions may be suitably welded as at 33. When so joined together the hat deformation 31 of the first sheathing member 26 plus the edge overlapping portion 32 of the second sheathing member 27 forms a box section in cross section which has great torsional strength.

The second sheathing member 27 likewise includes a longitudinal deformation along its upper edge as at 34 which is likewise of inverted hat section. The latter hat 34 cooperates and is received in the aligned cut-outs 30 of adjacently spaced carlins. In the same manner the next adjacent sheathing member 28 overlaps sheathing member 27 at its hat section 34 and is likewise joined to form a longitudinal stringer of box shape in cross section. In order to compensate for the loss of material in the carlins due to the cut- outs 29, 30 bracket members 37 of angle construction are affixed to the web of the carlins at the base of the cut-outs. The angle member includes a longitudinally extending flange 38 which supports the under lower surface of the hat deformation 29.

A modification of the roof structure of FIG. 1 and embodying this invention is shown in FIGS. 4 and 5. The modified form of the invention includes composite carlin members extending transversely of the vehicle between the side walls 12 of the vehicle. Each carlin 45 includes a lower arcuate Z-shaped member 46 which extends completely across the width of the car and is supported on its ends by the aforementioned roof sill members 16. A plurality of arcuate angle members 47 are disposed in projecting relationship above the top edge 48 of the lower carlin member 46. Each angle member 47 includes a downwardly depending flange 49 which is secured to the vertical flange 50 of carlin member 46. The angle members 47 include in addition top horizontally extending flanges 51 which are arcuately curved and support sheathing members 26, 27, 28 as arranged in the previously described FIG. 2. Adjacent spaced upper carlin angle members 47 as seen in FIG. 4 include edge portions 53, 54 which together with the top surface or flange 48 of carlin member 46 define a cut-out 57. The cut-outs 57 are like spaced as to adjacent longitudinally disposed carlins 45. These cut-outs serve to receive the inverted hat portions 31, 34 of adjacently disposed sheathing members. As previously indicated the lower longitudinal edge portion 32 of intermediate sheathing member 27 is shown in overlapping engagement and afiixed to the marginal edges of hat deformation 31 of lower sheathing member 26. A like construction is shown to exist between upper sheathing member 28 relative to intermediate sheathing member 27. From the above desscn'bed construction it is seen that discontinuity of the longitudinal stringers at each transverse carlin member is eliminated. This construction thereby saves the labor in assembling the various members together. Moreover costs are in addition saved by the elimination of leaks as a result of cutting down on the number of joints.

While there have been described what at present are considered to be the preferred embodiments of this invention it will be obvious to those skilled in the art that various changes and modifications may be made therein.

What is claimed is:

1. A roof construction for a vehicle having side frames and comprising in combination, a plurality of carlins spaced in adjacent relationship along the length of said car, said carlins extending transversely of said car and mounted for support by said side frames, each of said plurality of carlins having a top edge defining an opening therein, first and second sheathing means supported on the top edges of adjacently spaced carlins, said first sheathing means including a longitudinally extending deformed portion received into said openings of said adjacently spaced carlins, and said second sheathing means including an edge portion overlapping said deformed portion of said first sheathing member and secured thereto.

2. In the roof construction as set forth in claim 1 and including reinforcing means afiixed to each said carlin adjacent said opening.

3. In the roof construction set forth in claim 2 wherein said reinforcing means includes an angle member, and
