To alii whom it may con cern:A
Be itknown that I, WALTER P. MURPHY,
a citizen of the United States, and a resi sists in a new type of roof made of plates of heavy gage sheet metal which is free from the defects of heavy gage metal roofs of the types heretofore used.
Roofs made of heavy plates riveted together and tothe car frame lwork loose in service and leak. The so-called flexible metal car roofs, in which the roof sheets are loosely held upon the roof substructure and are free to move somewhat with respect to each other, are not water-tight and the roof sheets work out of place in service.
The metal car roof which is the principal object of this invention is composed of root' sheets which are rigidly attached to thereof substructure at the ridge, and which are freely movable with respect tto the rootl substructure at the eaves. The roof sheets are arranged crosswise of the car extending from eaves to eaves, and are lapped and secured together along their adjacent edges, forming a complete water-tight covering for the car irrespective of 'the roof substructure and of the means for attaching the roof sheets..
thereto. i Other objects, and 'advantages of the invention appear in connection with the fol lowing description of the embodiment there of' illustrated in the accompanying drawings;
In the drawings, wherein like parts are designated by the same reference characters in the several views, Figure 1 is a plan view of an end portion of a car root/embodying the invention, top parts of the roof being broken away to disclose the parts beneath; Fig. 2 is a half end elevation of the roof and a half transverse section of the same on the line Q-Q in Fig. 1; Fig. 3 is a side elevation of the portion of the roof shown in Fig. 1;

In the-drawings, the invention is shown applied to a car having wood side plates 11 and end plates l2, but it is also adapted to a 'car having metal side and end plates.
The roof substructure consists of inverted T-shaped cai-lines 13 which are bolted to the -i side plates, and metal purlins 14 of` channel shape with their ends supported onand securely riveted to thebottom-flanges of the carlines. The ends of the carlines are located in notches in the tops of the side plates, and their extremities are bent down outside vof the sid'e plates.
esy
gage sheet metal, are arranged crosswise of the car with their ends resting onthe side plates and their middle portiori supported en the purlins. The roof sheetsare formed with stiifening corrugations 16 which eX- tend from end to end of the sheets at spaced intervals and strengthen them against buckling under any weight likely to come upon them. The roof sheets are somewhat wider than the spaces between the carlines, and their side margins are formed with doubledup flanges 17 of approximately inverted V- shape having round tops and slantingside walls. These flanges 17 extend from end to end of the roc f sheets, and straddle over the vertical webs of the carlines, the proximate flanges of adjacent roof sheets lapping and'A embracing each other' to "dorm standing seams or lap joints between the roof sheets.
The ends of the roof .sheetsabetween the side flanges 17 are provided with straight downturned flanges 18 which overhang the side plates of the car. The end flanges 18 are spaced away from the side plates near beneath the ends'of the roof sheets; and support the latter where the side -plates are notched to receive the ends of the carlines.
At each end of the car an anglel shield strip 21 is secured to the end plate. The horizontal flange -of the langle shield lays over the end-margin of the end roof sheet, and its inner edge 22 is bent down to rest flat on the roof sheet within the outer cor-4 rugation 16 of the latter.
The rooisheets are rigidly bolted to th carlines by bolts 25 at the ridge of the car...
The heads of the ridgeboltsy25 are slipped into dove-tail. or inverted T-shaped slots in j the top ilanges of the vertical' webs of the carlines, and are'secured therein by perforated saddle blocks 26 which are slipped onto the shanks of the bolts 'and seated` astride of the top webs of the 'carlines The tops of the ridge bolt retaining blocks are' rounded to conform to the under side of the standing seam flanges of the roof sheets, and the roof sheets'rest directl Holes are made in the tops'o" fthe seam 4flanges at the ridge through which the bolts y25 pass.

ers have flanged holes at the ridge for the bolts 25.
of the seam covers and firmly secure the latter and the roof sheets to the carlines at the ridge. Leather or soft metalwash'ers 29 may bc placed between the nuts 28 and seam vcovers 23, into which the flanges surrounding the bolt holes in the latter may sink, thereby making tight joints around the ridge bolts to keep. out water. l
f Running board saddles 30 rest upon the seam covers, and are provided with holes at the ridge for the bolts which' secure the roof sheets and seam covers to the carlines. rlfhe upper ends of the bolts 25 pro ject through the running boald saddles, andj nuts 31 secure the lattes toA the roof. Thel ning board saddles.

on them:
holes through the running board saddles are counter-bored at their upper and lower ends to forin recesses for the nuts 28 and 31. Cover plates 32 are arranged across the running board saddles over the upper recesses.- Running boards 33 are nailed'to the run- The end running board saddles rest loosely on the angle shield strips at the ends of the car, and the ends of the running boards project beyond the ends 1 5 of the oarand are secured together 'and supported by brackets 34.
The seam covers are securedto the car at the eaves by eaves caps 35 which fit-.over the ends of the seam covers and are bolted to the side plates and to the end of the carlines. The eaves caps are somewhat wider than the seam covert,` and their side and' front walls cover` the open ends of the stand-v ing seams and the'spaces between the downturned end' lflanges ofthe roof sheets. On vtheir und'er sides the eaves caps have ledges 36 and webs 37 which rest in the 'angle ofthe flashing strips over the side sheathing of the car and thereby position the eaves caps away from the ends ofthe standing seams. Sufficient space is left between the eaves caps and flashing strips forair to circulate into and out ofthe car through the ends of the standing' seams and between them and the flashing strips. The webs\ 37 act as varies or air deilee'tors,4 and causeetheaair current between-the eaves caps' and flashing due to the motion of the carto blow into the'ends of the standing seams on the Windward side, and also protect the egress offair from rIthe 1e space between the eaves caps and flashing strips also permits the end yflanges of the roof sheets to'move freely with respect to the eaves of the car. Bolts 38 through the lower eaves flashing strips to the side of ,the car. Bolts 39 with their heads secured in dovetail or T-shaped slots in the ends of the Webs of the carlines project outwardly through the eaves cap'sand secure the latter to the ends of the carlines. The' bolts 39 are held i in place in the carline slots by means of Nuts 28 are screwed down hard on the tops V-s aped clips 40 arranged` astride 'of the carliL e webs and having holes in their twol brancheswhich embrace the'heads of the bolts. 't
nMFig. 12 a modified form of eaves cap 41 is shbwn which is adapted for cars having m'etah angle or Z-bar side plates 42. The fro tlwall of the eaves cap 41 is spaced fronlthe eaves flashing strips l13 to permit circ lation of air into and out of' thecar. Themaves caps prevent water from blowing causing air to circulate into and out of the car and thereby keep the under sides of the roof sheets dry.
' 'ends of the eaves caps secure them and the vdirectly into the open ends of the standing seams, and 'at the same time they assist in incassa an From the preceding description it is evident that the root' sheets are mutually dependent, that is, they coopera-te to retain each other in position; and collectively they form a substantially complete and self-contained water-tight covering extending from side to side of the car over its full length. The roof sheets are unsecured to the car eX- cept along the ridge line; hence lateral vibration and relative lengthwise movement of the sides and ends of the car are not directly transmitted to the roof, and relative movement of one roof sheet with respect to another is not occasioned thereby. The shape of the lapped margins of the roof sheets permits one root sheet to slip over or under its neighbor lengthwise of the car at the eaves to the limited extent permitted by the eaves fastenings and the seam covers at all times hold the lapped margins of the roof sheets in contact with each other for their entire length; hence the roon can accommodate itself to sagging or bowing of the side plates, or twisting of the sides or ends fof the car out of square Without the roof sheets becoming spread. Also no movement of the roofplates with respect to each other or with respectI to .the roof substructure is possible at the ridge, and hence each rrootvl plate is firmly secured in transverse alinement with the center line of the car roof irrespective of the vibration and distortion of the roof substructure.
