CAR ROOF C. D. BONSALL Fild oct. 1o, 1930 YApril 12, 1932.

Patented Apr. 12, 1932 UNITED STATES PATENT "OFFICE I cHAnLEs DAVID PoNsALI., or PITTSBURGH, PENNSYLVANIA, AssIeNoR To P.VH. MOP.- PHY COMPANY, 'oF NEW KENSINGTON, PENNSYLVANIA, A CORPORATION OP' PENN- SYLVANIA CAR ROOF.

Application filed. October 10, 1930. SerialNo. 487,656;

This invention relates to car roofs of the type wherein the metal roof sheets are rigidly secured together and to the carlines along their adjacent margins. It has for its @principal objects to produce a strong and light weight roof of simple and `economical construction. that is easy of application and that will enable portionsof the sheets'to flex or bend relative to each other and toV the carlines and thereby prevent damage v"to the sheets when the car frameV is distorted in service. Other objects are to reduce` the height of the carline without sacrificing strength or headroom, to better provide for 16 supporting the sheets on the carlines, and to facilitate the operation of riveting the sheets to the carlines. The invention consists prin` cipally in spacing portions of the sheetsfrom the carlines to which they are secured vso that said sheets may flex relative to the carlines and to each other; it also consists in providing the carlines with portions that serve as supports for the roof sheets; it also consists in the. arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specification andl wherein likesymbols refer to like partswhereverthey occur, Y a

Fig.,1 is a plan view of a portion of'acar roof embodying my invention,

Fig. 2 is an enlarged vertical transverse cross-section through the roof on the line 24,-2 in Fig. 1, Y

'.Fig. 3 is a vertical section on the line 3-3 in Fig. 2, y

Fig. 4 is a vertical cross-section on the line 4-4ofFig.2;and

Figs. and 6 are vertical sections similar to Fig. 3, showing modified seam construc, tions.

The present construction comprises Z-bar c side plates A' connected by carlines B, and roof sheets C extending from side plate to side plate and covering the spacesbetween carlines. The Z-bar side plates A are preferably arranged with the inner flange upstanding and having anA angle-shaped sup- 50 port D riveted flatwise to the outer face of said iiange. The upper flange 2 of the angleshaped support D extends inwardly over the' side plate beneath the roof sheets C atan angle corresponding'to theslope thereofat thel proper elevation for the end portionsof said roof sheets to rest upon.VL At suitable intervalsjthe upper flange 2 ofthe angleshaped support D is provided in its top with depressions 3 shapedto ,receive and form seats for the ends of the carlines B, which Y...

are riveted thereto;

The carlines B are made up of two'meml berseach, an `upper member 4 and a lower member 5. The upper member 4 comprises an inverted channel with outstanding base flanges 6 at the lowervedges of itsV side walls, the channel'being of uniform ydepthffrom the ridge to pointsv adjacent tothe eaves where it is curved downwardly to close yits ends.

The lower oarline member 5 is in the form'of y a plate that is riveted to the base iiang'es of the inverted channel-shaped upper carline member 4. The lowercarli'ne memberv yis wider than the upperfcarline member 4.and

has its side marginal portions oEset .upfr wardly beyond the b a'se iianges 'of said upper carline member to form raised Yflanges'` or panels 7 for the roof sheets C to rest upon. y

The roof sheets C extend from side plate to side plate and are provided at their` ends with depending flanges 8 that overhang and that are preferably spaced fromA lthe' com# bined carline `and roof vsheet supports Dl and the upstanding side plate flanges l, to which said supports areseoure'd.v VThe roofsheets are provided along Oppositej side margins with inverted channel-shapedV side marginal flanges or hollow ribs 9 that extendjfrom end to end of the roof sheets. j The channelshaped sid-e marginal flanges 9 of adjacent roof sheets fit and interlock with each other. and straddle the carlines. Said anges are riveted flatwise7 as at 10,-V to the tops yof the carlines B and are so wide :that the side walls of said ribs are spaced` from the side walls of said carlines. This arrangementv affords clearancebetween the sheet ribsand carline'son both sides of the latterand thus permits the portions of the .sheets between carlines to shift or flex and Ain this manner accommodate themselves to the distortions to which the car frame is subject in service.

Holes 11 are formed in the bottom member 5 of the carlines below the rivets 10 so as to facilitate riveting. Any water that gets under the roof sheets. ontosaid lowerAv carline 5, each of sheet C is provided alongone side margin with a simple upstanding flange l2 that lies flatwise against one side ofthe carlineBand alongitheopposite side margin with an inverted. channel-shaped. flangel or hollow rib 13.1that clears'the near side of'said carline but has its-outermostflange or wall bearing flatwise. against the simple upstanding. flange 12 ofL the' adjacent sheet. The sheetsare secured `together land to the carline by a singlerow of rivets la that pass horizontally throughthe overlapping p ortions of the sheet flanges and the adjacent side wall ofthe carline.` Y

By the arrangement described,` the roof sheets. have their. adjacent. margins supported on and rigidly` secured to. the carlines, but, at the same :time,a re capable of flexing, or shifting independentlythereof. when the car frame distorts inservice.. rlChe carlinerconstruction functions after thek manner off a: hollow box girder.;V it enables the height of the carline to. bereducedwithout sacrifice of strengthor headroom; andit, provides a bettery support for tlief roof sheets and. also facilitates the operation of riveting. the` roof, sheets to the carlines.-`

The modified construct-ion', of Fig, ,6. shows a one-piece outside carline, as distinguished from the. twofpiece inside` carline construe.- tions hereinbefore. described. The4 outside carline B. of'this construction comprises a singlel member of inverted channel-shaped cross-section havingoutstanding base flanges which bear flatwiseupon the body portions of adjacent roof sheets. The roof sheets are similar4 to those shown in Fig. 5;*that'i's, each sheet C is provided) along oneside margin with its simplelupstand'ing flange 12a and alongthe opposite silde margin with inverted cl'iannellslapedilange or hollow rib' 13a; In this construction, however,- the cooperating flanges ofadj acent roof Vsheets are located inside th-e'outsidefcarline B with the outer wall oftheihollow rib lafof; one sheet; lying flatwisei against` the inner facel of one side wall of said carliney and overlapping the simple upstanding flange 12a of' the adjacent sheet. The sheets are rigidly securedtogether and to :thel carline by a row of. rivets 14a that pass horizontallyv through the mferlapped` portions of said sheets andthe adjacent side wall of said-.carline.v The ,channelofthe outside vcarline B is made deep enough and Wide enough to afford clearance between the said carline and the hollow rib 13a at the top and unsecured side wall of said rib. With this arrangement, the space between one side wall of the hollow rib 13a and the adjacent side wallof., the carline permits the body. of the sheet to flex or shift transversely of the carline in accommodating itself to the weaving ofthe car, while the space betweeen the top of said rib and the top of the carline-permits the top wall of said rib to tiltcrosswise during such flexing or shifting of the sheet.
