CAR ROOF.

Application filed October 19, 1925. Serial No. 63,433.

This invention relates to car roofs and particularly to all-metal car roofs of that type in which the` carlines are arranged above the roofingsheets `and form the supports `and weather-proofing caps therefor.

Theinvention has among its objects to improve `generally thisparticular type of car roofs and further relatesto a simplified and improvedconstruction of running board sad- 10.dle and to a roof sheet fastening means designed to be also employed as a fastening means for the runnimr board saddle Various other ob]ects, 'advantages and novel details of construction of the invention will be made more lapparent as thisdescription proceeds, Iespecially when considered in connection with the accompanying drawings, wherein 1 y Fig.` 1 is a `fragmentary transverse sectional elevational `view of a car roof constructed in accordance with my invention,

Fig. 2 is a top plan View of `the structure illustratedin Fig. 1,

Fig. 3 is a fragmentary side elevational View of a car roof constructed in accordance with this invention,

Fig. 4 is an enlarged` detailed sectional view taken substantially on the plane indicated by line 4-4 inFig. 1, and

`. Fig. 5 is asimilar sectional view taken substantially on the planeindicated by line 5-5 in Fig. 1. c

Referring now particularly `to the drawings wherein like reference characters indicate like parts, it will be noted that there is illustrated carlines of inverted Ushape in cross section provided with side flanges 11 and side plates 121of Z cross section, the car- 3;,L lines being turned down over the side plates and having their ends secured `thereto means of rivets orv the like 13 passing pref erably through the'endsof the side flanges 11. In kthe cinstruction herein shown spacing washers 14 are arranged between the upstanding flange of the side plate 12 and the flanges 11 of the carline.

The roof sheets 15 are provided with upwardly offset returnbent side edges 16, the roof sheets being mounted upon the car with the edges 16 thereof arranged in overlapping relation, as clearly shown in Figs. 4 and 5. The overlapping edges 16 of adjacent roof sheets extend up within the adjacent carline 10 and are enveloped thereby.

In practice a non-metallic washer 17, preferably of impregnated felt. or canvas, is interposed between the roofing sheets 15 and. the carline 10 in the manner -clearly illustrated in F igs.4 and 5.` Consequently this washer in connection with the cartine l() weatherproofs the joint between the adjacent roo-f sheets. c l

For supporting the roofsheets within the carline there is provided a plurality of spaced sheet fastening members 18 in the form of shoulder' bolts, leach `having an enlarged shoulder portion 19 arranged between the overlapping edges ofthe `roof sheets 15 and the under sidewof the crest of .the carline to thereby space the overlapping roof sheets from the crest of the carline. The upper end of each shoulder 'bolt is riveted over as at 20 and consequently the opening in the carline through which the 'bolt passes is weather proofed. Associated with each bolt 19 is a sheet supporting bar 21 held in place by nut 22 threaded on the lower end of the bolt. A `lock Washer 23 is preferably interposed `between the sheet supporting bar' 21 and the nut 22.

The running board saddles 24 are attached directly to the carlines and each saddle comprises a flat horizontal poition 25 and a por tion 26 engaging the crest of the carline and preferably correspondingly shaped .so as to effect a positive engagement therewith. The running boards 27 restupon the horizontal portions 25 of the saddle and are secured thereto vby bolts 28 passing through the boards and through suitableapertures arranged in the. saddle. As shown by dotted lines in Fig. 5 thesaddles 24 varranged at the splicing points of the running board may have the horizontal portion 25 duplicated as indicated at 25. Y f

For simplifying andlcheapening the cost of construction and assembly the `running board saddles 24 are preferably secured in place upon the cai-lines 10 by certain of the sheet supporting shoulder bolts 18 and therefore, as shown in Fig. 5, the upper ends of the shoulder bolts 18'at the points where the running board saddles 24 are located, are extended upwardly through aligned openings in the running board saddle and the heads 20 thereof riveted over so as to rigidly connect the running board saddles Ato the carlines at the crests thereof.

From the foregoing it will be apparent that the present invention offers a simple and cheap means of efficiently Connecting the roof sheets to the carlines and of likewise Connecting the running board saddles thereto without a duplication of fastening means. Furthermore, the assembly of the roof is facilitated because the sheet fastening means are previously fixed by riveting to thel carlines as shown the shouldered portions of the shoulder bolts employed in the present in- Lvention affording positive means for spacing the overlapping ends of the roofing sheets from the crest of the carlines and positioning the nuts of these bolts sufficiently near the plane of the under side of the roof to enable them to be conveniently tightened.

While an ei'nbodiment of the invention is illustrated and described somewhat in detail, it will be readily apparent that various changes in the specific form illustrated may be resorted to without departing from the spirit and scope of the invention and to this end reservation is made to malte such Changes as may come within the purview of the accompanying elaims.

What I claim as my invention is:

l. In a car roof, the combination with earlines of inverted U-form having shoulder bolts riveted thereto, of roof sheets extending up within the carlines into engagement 'with said shoulders, and means carried by said bolts for fastening the sheets thereto.

2. ln a car roof, the combination with earlines of inverted U-form, of roof sheets having overlapping upwardly offset side edges renveloped by the cai-lines, and shoulder bolts within said carline and means on said bolts Cooperating with said shoulders for elamping the roofing sheets to said carline,

Il. In a car roof, the combination with a carline of inverted U-form, and roo f sheets extending up within the carline, of a sheet. fastening means comprising a shoulder bolt riveted to the crest of the carline with the shoulder thereof spacing the sheets from said carline.

5. In a car roof, a carline of inverted U- form, roof sheets having overlapping edges extending up within said carline and sheet fastening means comprisingr a shoulder holt secured to said carline with the shoulder thereof arranged between said carline 'and sheet edges for spacing the latter.

G'. ln a car roof, a carline of inverted U- shape, shoulder bolts riveted to said earline and extending within the same. roof sheets provided with overlapping upwardly otlset edges extendingr within said carline and means on said bolts for clamping said roof sheets against the shoulders of said bolts.

7. In a car roof, a carline of inverted U- form. roof sheets having overlapping upwardly offset edges extending upwardly within said carline, shoulder bolts riveted to said carline and extending through said overlapping sheet edges and means on said bolts for clamping said sheet edges a ainst the shoulders ol said bolts- 8. ln a. car roof, a earline of inverted U- form, rooting sheets having overlapping upwardly offset edges extending upwardly within said earline, and a holt extending through the carline and they edges o' the rooting sheets, the. said bolt heilig provided with an enlarged shoulder portion intermediate its ends7 one end ol' the said enlarged portion hearing against the underside of the said carline and the other end of the said enlarged portion l'iearing against thel said rooting sheets.

9. ln a ear roof, a carline of inverted U- form, roof sheets having overlapping upwardly oll'set edges extending upwardly within said carline, a bolt extending through the said carline and the said rooting sheets, the said bolt having an enlarged port-ion intermediate its ends for sparing the said roof sheets from the said earline. the said enlarged portion forming ol'ipositely facing shoulders on the bolt, means formed on one end of the bolt for clamping the earline against one of the shoulders and means earried by the other end of the bolt for clamping thel roof sheets against the other ol' the said shoulders.

ln testimony whereof l allix my signature.

DAVID W. i-iAwKswoR'rn.
