CAR ROOF.

Application filed September 15, 1921. Serial No. 500,768.

To @ZZ ily/i077?, t 'may concern.

Be it known that l, JOHN Pnnnson, a citizen of the UnitedC States, residing at Chicago, in the county oi" Cook, State of lllinois United States of America, having invented certain new and useful improvements in Car Roofs, do hereby declare that the following is a full7 clear, and exact de scription of the saine.

lily invention relates to car-roots, and consists in the novel and useful constructions herein described and then pointed out in the appended claims.

ln the accompanying drawings7 which illustrate practical embodiments of the vari ous features of my invention and in which the same reference numerals indicate siniilar parts in the different figures, F l is a t fp plan view of part of a car-root embodying the features ot my invention with various parts cut-away to atlord better illustration; Fig. 2 is a cross-sectional view along the line of one oi the carlines with its topcap and end-cap omitted; Fig. 3 is a. detail sectional view oit one or the carlines and associated parts; Fig. l is a detail view partly in section and partly in perspective showing one of the end-caps in place5 and Fig. 5 is a detail sectional view on the line 5--5 in Fig. l.

ln the drawings the reference numeral l indicates the ridge-pole, 2 the side-plates. 3 the side-sheathing, 4 the end or body carlines, 5 the longitudinal wooden purlines, and 6 the roof-boards extending from the ridge-pole to the side-plates; the ridge-pole and body ca-rlines are oppositely inclined from their centers to contorni to the pitch of the roof. Extending transversely or' the roof at suitable intervals are the carlines which in the present invention are composed of wooden sub-carlines 7 and metal topplates 8 extending from the ridge-pole to the side-plates. The bodies of the sub-car`- lines 7 are rabbeted at each side to form seats for the sides of the metallic roof-panels 9, and they are bolted to the ridge-pole and purlines by bolts l() having their heads countersunk into their ridges or raised cen trai portions ll. The top-plates 8 are of less width than the lower portions of the sub-carlines, but are wider than their ridges to which they are secured by wood-screws 12 having their heads countersunk therein. The inner ends of the opposite sections of each cai-line are straddled by a suitable metallic ridge-cap 13 which is bolted as at le to the ridge-pole. The outer end of the body of each subcarline is shouldered or cutaway on its lower side at l5 to allow its ridge ll to overlie a wooden strip i6 arranged upon the side-plate 2 aga-inst which the outer ends of the 1.'ooi-l: oards 6 abut, and the outer end oit each 'top-plate S is reduced in width to form a depending wing il" constructed to be bent down over the t'aeia i8. ifi iflrashing 19 is arranged upon the stri )s 16 and acias 1.8 to underlie the outer ends of the ridges ll and root-panels 9, and a carline end-cap 2O fits over the outer end ot each carline, being secured to the wing 17 by a. bolt 2l and having a lag-screw Q2 passing through its skirt into Ythe sideplate. The top-plate thus forms a` fastening or anchor for the end-cap.

The roeic sheets or panels 9 extend from the ringe-pole outward to the eaves resting upon the flanges ot the carlines and the flashings; each sheet or panel is substantially rectangular in shape and is provided with the usual upturned side-iianges 23 that lie under the plates 8 of the carlines, with sullicient clearance between the parts to allow play to the plates along their length. The seats for the roof-panels formed by the side flanges et the carlines are straight from end to end and the webs or ridges ll are of uniform height so that the roof-panels are carried on the carlines with their flanges under thev top plates upon which the carlinecaps are in turn supported so that all these parts are interlocked.

The carline-caps are formed oit sheet metal of inverted trough-shape in cross-seo tion. each consisting of an upper horizontal top 24 of suilicient width to overlap the car line-plate 8, sides 25 of suilicient depth to iorin a skirt reaching to the panels, and inwardly directed flanges 26 bearing on adjacent panels; they extend from the ridge-'pole to the eaves, and each is provided with opposite inwardly projecting ribs 27 in its sides 25 which engage the under faces of the top plate S of the carline. These ribs are formed by inwardly bending or swaging the material of the sides at a. suicient dista-nce below the top to provide an intervening passage or channel to snugly receive the edges of the plate1 and preferably are at the center of the sides, leaving the ends thereof plain extending along the center ot the sides a sutlicient distance to firmly lock the caps on the cai-lines. After the roof-panels are assembled upon their supporting bases between the carlines, the carline-caps are -slipped into place on the carlines with their ribs 27 under the carline plates 8, each being slid along the length of the associated carline beginning at its outer end from the eaves to the ridge-poles and its sides 25 enclose the flanges 23 of the adjacent panels; When the cap is in position it is held against vertical displacement by its ribs, and its lateral flanges 26 hold the associated panels down on their bases, those parts thus being interlocled together to hold the panels and caps in place and provide a -weather-prool joint, but leaving sullicient clearance between the flanges and the earlines and caps to provide a flexible joint to permit the panels to move un der strains or twisting actions t' the car and so prevent the buckling of their bodies or the fracture of their joints. The end-caps are then positioned overthe outer ends or the earline-ca )s and the Wings of the plates 8 to which they are bolted as at 2l, and are fastened to the car-body by the rlag-screws 22, and the ridge-caps 13 are positioned over the inner ends of the. carline-caps; the caps also carry thesaddles 2S for the running-boards 29.

The oai-line composed of the Wooden body and metal top-plate is of advantage in making repairs and replacements oit car-roots, as the parts are easily and quickly 'assembled Without disturbing surrounding-elements, and the cost of an all-metal carline is appreoiably reduced Without sacrilicing any util-ity as a base for the adjacent sheets or panels and to which kthey can be interlocked by the caps.

I claim:

l. ln a car-roof, a carline composed of a Wooden body having a central ridge and a metal top-plate secured to the ridge and eX- tending beyond its sides from the ridge to the eaves, roof-panels adjacentthe carlines and having upturned lateral flanges adjacent the ridges thereof and under the topplate, and a cap on the plate covering the flanges of adjacent panels.

2. ln a car-roo', carline composed of a Wooden body having a central ridge and a metal top-plate secured to the ridge and eX- tending beyond its sides from the ridge to the eaves, rooitpanels adjacent the carlines and having uptnrned lateral flanges adjacent the ridges thereof and under the topplate, a cap on the pla-te embracing the flanges of the panels, the outer end of the plate providinga Wing constructed to overlie the end otl the ridge, and an end-cap bolted to the wing.

3. ln a car roof, a carline composed oi' a Wooden body having a central ridge and a metal top-plate secured to the ridge and eX- tending beyond its sides, root-panels adjacent the carlines and having upturned lat eral langes adjacent the ridges thereof, a

Arap on the carline having sides extending down upon the panels outside their flanges and provided with inwardly directed ribs to enga-gethe sides of the plate, the outer end olE the plate forming a Wing to overlie the outer end of the ridge, and an end-cap bolted tothe Wing.

et. ln a oaraooi, a carline composed of a Wooden body having a central ridge and a metal top-plate secured to the ridge and extending beyond its sides and outer end, the body being cut-away atits outer end, a flashing-strip under the carline-ridge, the outer end oi' the top plates forming a Wing to overlie the end of the ridge, roof-panels adjacent the carline having flangesa carlinecap embracing the plateV and coverine the hanges, and an end-cap on the end or the farline-cap and bolted to the Wing.

In testimony whereof l ailix mylsignature.
