GEORGE W. BISTINE, J R., OF CHICAGO, ILLINOIS, ASSIGNOB TO PRESSED STEEL CAB. COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORIORATION OF NEW JERSEY.

CAR-ROOF.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed May 11, 1917. Serial No. 158,367.

To all whom it may concern:

Be it known that I, GEORGE W. RrsTINE, Jr., a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in CarRoofs, of which the following is a specification.

This invention relates to an improvement in car roof construction, an object being to provide a roof having a maximum of strength with a minimum weight and which will be simple'in construction and capable of being manufactured at low cost.

Another object of the invention is to provide an improved carline which can be made of a commercial section or pressed shape, to which the roof plates are adapted to be attached by resilient means and without the use of rivets passing through the roof plates.

Another object of the invention is to provide simple means for the attachment of the roof plates to the carline, which, while forming Weatherproof joints between the roof plates and carline, will permit of the easy removal and replacement, when necessary, of such plates.

Another object of the invention is to provide means for attaching the roof plates to the carline in such a manner that such means is so anchored to the side plates, that u large proportion of the strain due to holding the roof plates in contact with the carline is transmitted to the side plates.

Referring now to the drawings in which like reference character refer to like parts, Figure l is a plan view of a portion of a car roof embodying the invention; Fig?. is a sectional View of the same taken on the line 2-2 of Fig. 1 and Fig. 3 is an end elevation of the same. Fig. 4 is an enlarged sectional view taken on the line 4-4 of Fig. 1, and F ig. 5 is a cross sectional view taken on the line 5-5 of Fig. 1; Figs. 6 and 7 are sectional views of a modification of the invention, which views correspond to Figs. l and 5 of the preferred form.

Referring now in detail to the drawings, 1 indicates one of the side plates of the car which may be of any suitable form or construction, but as shown in the drawings are preferably of angular cross section. 2 indicates one of the carlines which extend across the car and are secured to the side plates 1. These carlines may be of any suitable form but are preferably of rolled or pressed channel form having a horizontally disposed web 3 and vertical flanges 4 which extend upwardly therefrom.

The roof comprises a plurality of plates 5, 5, which rest on the flanges 4 of the carlines and preferably extend continuously' across the full Width of the car. Each of these roof plates is provided with downturned end and side flanges 6 and 7 respectively, the end flanges 6 overlapping the side plates when the roof plate is in its propel' position on the carline 2, and the side flanges 7 extending into adjacent carlines. The side flanges 7 are provided with perforations S at intervals throughout their lengths which are adapted to receive members 9 for fastening the roof plates to the carlines. The members 9 are located within the carlines and between the side flanges t of the roof plates, and are slightly bowed or curved, the side portions l() of the members passing through the perforations 8 of adjacent roof plates. The lower portions of the side flanges 7 of the roof plates are doubled upon themselves, so as to provide additional thickness of metal and strength in that portion of the flange which is slotted for the ends 10 of the members 9 to pass through.

llindicates bolts which extend from side to side of the car and are anchored in bracket members 12 which are secured to the side plates 1 at the ends of the carline. Between the bracket members 12 these bolts seat in grooves or recesses 13 formed in the upper surface of the members 9, and when the nuts 14 at the ends of the bolts are tightened against the bracket members 12, the tension on the bolts tending to straighten them, roduoes a downward pressure on the mem ers 9, which engage the side flanges 7 of the roof plates, thus holding the roof plates to the carlines. The curved form of the carline, curving downwardly to each side of the can insures that water falling in the channel of the carline will be conducted to one or both ends thereof, and permitted to escape through slots or notches 17, 17, which are out in the end flanges of the roof plates.

In the modification of the invention as shown in Figs. 6 and 7 the transverse bolts l1 of the preferred form are omitted, and the carline is provided with a plurality of shoulder bolts l5 which are secured in the web of the carline and are adapted to extend through the members 9, the upper ends of these bolts being provided with a threaded portion adapted to receive a nut 16, which nut when ti htened produces a downward pressure on t e members 9, which engage the side flanges T of the roof plates, thus holding the roof plates to the rarline.

It is to be understood that the members 9 may if desired be made of material having more or less resiliency, thus roviding for a greater amount of movement between adjacent roof plates, and a greater amount of movement. between the roof plates and the carlines which support them.

It will be noted from the foregoing description that the root plates are held to the upper jtrame work oi' the ear without rivets, and also that they are held in suoli a manner as to permit slight movement between the plates as the oar weaves due to uneven track and other servire conditions.

Aalthough in the drawings and foregoing descrip-tion only portions of one carline and the roof plates. and the several parts ooperating therewith are illustrated and described, it will be understood by those skilled in the art. that both ends of the oarline are substantially alike` and that a railway ear roof is composed ot a plurality of suoli parts.

Claims:

1. ln a oar roof, a oarline, root1 plates supported by said rai-line and having openings formed therein, members engaging said openings, said members having grooves in their upper surfaces and means engaging said grooves to retain the roof plates on said earline, and means for applying tension to said means.

2. In a car roof, a carline, rooplates snpported by said earline and having openings formed therein. resilient members engaging said openings, said members having grooves formed in their upper surfaces, and means engaging said grooves to retain the roof plates on` said earline, and means for applying tension to said means.

Copies of this patent may be obtained for 3. ln a ear roof, a oarline, roof plates supported by said oarline and having openings formed therein, members engaging said openings, said members having grooves formed in their upper surfaces and a rod extending from side to side of the roof, adapted to engage the grooves in said members and retain the roof plates on said earline, and means for a plying tension to said rod.

i. lh a car roof, side plates, a earline, roof plates supported by said carline and having openings formed therein, members engaging said openings, said members having grooves and a rod extending from side to side of the roof, adapted to engage the grooves in said members and retain the roof plates on said cai-line. said rod being secured to said side plates, and means at the sides of the roof for applying tension to said rod.

ln a car roof, a oarline of flanged seotion, roof plates supported by the flanges of said oarline, lianges on said roof plates eX- tending between the flanges of said earline and having openings formed therein, members engaging said openings, said members having grooves formed therein and rod means engaging said grooves to retain the roof plates on said oarline., and means for applying tension to said rod means.

G. In a oar roof, a oarline, roof plates supported by said earline, flanges on said roof plates and having vportions folded upon themselves and openings formed in said folded portions, members engaging said openings, said members having V.grooves formed in their upper surfaces and means engag' said grooves to retain the roof plates to sai carline, and means for applying tension to said means.

In testimony whereof I atlix my signature in the presence of two Witnesses.
