Application tiled November 27, 1908: Serial No. 464,706.

To .all whom it may concern: l

Be it known that I, EDWARD PossoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovergents inCar-Roofs, of which thefo owing is specification.

' The object of my invention is to provide l. new and improved sheetfmetal roof for freight cars.

Another object -is to provide such a roof comprisin metal sheets overlying the roof framewor -and secured thereto in a manner to rmit straining of the roof vframework l5 wit out distortion of the roof sheets. Y

Still another object of my invention is to provide suitable means forholding the lateral edges of the roof sheets, at the same time permitting displacement thereof to a limited extent. f

These objects and others will be triade apparent in the fo lowing specification and claims, taken in onnection with the accompanying drawings, in which- Figure 1 is a. sidel elevation of my improved car roof. Fig. 2 is'a top plan view of the same showing the assembling 'of the roof in various stages. Fig. 3 is a transverse section of the car roof, taken on the 80 line 3 in Fig. 1. Fig. 4 is a similar section,

. taken on the line 4 in Fig. 1. Fig. 5 is a central longitudinal section, taken on the line 5 in Fig. 2. Fig. 6 is a sectional detail, taken on the line 6 1n Fig. 2. Figs. 7,' 8, 9

l5 and 10 are perspective details further illus/ trating my invention.

In the particular embodiment of my inventio which Ihave chosen to illustrate in the drawings, the roof framework comrises the ordinary carlines 15, ridge beam 6, side plates 17 and root boards 20. The upper endsof the boards 18, which comprise the side walls, are attached to the side late 17 between the same and the fascia 1). a *im e various elements which comprise the sheet metal roof will now be described in lapproximately the order in which they are applied to the ordinary board roof 20. Fig. 2 shows the roof in various stages of com- '50 pletion, the'oom leted roof` beingshown at the left-hand en of the ligure.

A sheet metal saddle 21 (Fig. 7) has its lateral edges 22 bent under and at eat-h end a 23 ls struck up, havinga central hole This saddle 21 is bent at rrobtuse and is then laidl across the ridge of the roof,

as shown at the rightl of Fig. 2. A hole 24- through the middle of the saddle 2,1 registers with a hole extending down through the ridge beam y1G of the roof.l

The roof sheets 26 (Fig.` are stamped in` -the shape shown in the drawings by means of a die. Onv `three sides,` the edges 27 are turned up obliquely and then they extreme edges 28 are rolled over (see F ig..6,). Near the 'end of thereof sheet 2G, a boss 30 is str uckup 4having a Acentral hole '31. The

sheets 26 are applied to the roof20, so that the bosses 30,011 the roof sheets shall register with the bosses 23 on the saddles.

The ridge caps 32 have'the edges-33 bent downto form channels. The extreme edges are bent out in the same planeand folded under, as shown inL F ig. 3. These caps 32 are laid over the ridge of the car roof, over` lapping the adjacent turned edges of op.- posite roof sheets 26 on either side.. of the car (sce Fig. Eachridge cap 3,2 has a central l1ole.3(l.which registers with` a hole in the ridge beam 16. A block 37 having the shape shown in-Fig. 3 islaid across the ridgeA cap 32 at its center. This block has, ockets 30 which lit down over the bosses 3,. The bleek 37 forms a support for the `running board. The iveightof the running board on. theI block 37 is transmitted through the bosses 23, but inasmuchas these are.. at a pivotal point, no` emisiderableobstruction is afforded to the displacementk of Vthe root sheets 20 about the bosses 2? as pivots. The bolts 3S pass through thefbloek 37 and the registering bosses 30 and 23, the nuts being applied inside the board rooii20.. The bolt Si) passes down through the ,renter ofthe block 37, thev ridge rap 32, the sheet metal saddle 2l and the ridgebeam 1G.V

'.l`h`e transverse. eapsl() (Fig. 9) have their sides 4.1 bent downto toi-lil a channel, the

extremo edges 12 being bont'ont in thesame plano and doubled undeiyhs indicated vby the relorencc numeral 43. Each transverse cap 40 is made in two sections with overlapping ends at the center, as indicated by the reference numeral 40". The meeting ends of the sections of the transverse rap 4() are notrhedas shown in the drawings and as indicated by the reference, numeral 45, so that the)v shall make a eloso 'l4 with .'the longitudinal caps 32. 'l`he overlapping ends 40 ot" the transverse raps have holes 47. The` angle to conform to the angle ofthe roof l block 48 having tht` shape shown in Fig. 4

' 'placed across the ridge of the roof between the edges of adjacent roof sheets 26. The transverse cap 40 is laid down across thea'djacent edges of lthe roof plates 26 and over the blocks 48 (see Fi 6) The projections '44 overlap theends o the rid e caps 32 and the notches "45, abut agatiinst t e l edges 34 of the roof ca s 32. A

er being applied as described, .tie ends 46'are bent down, thus closing the endsv of the transverse caps.

. Next, the-'saddle blocks 49 are placed ontop of the transverse caps 40 directly/l over the blocks 48. The bolts 51 are assed down through the two blocks 48 an 49, havin the transverse ca 40 between them, an through the ridge'ieaml.

The lower or outer edgesjof the 'roof sheets 26 are simply doubled under, as indicated by the reference numeral-52. Clips 53 are fastened by means of s ikes 54 to the side walls 18 and the side pi) clips hook 'up over the outer side ed es of thegplates 23, as shown inFig. 3,-but o not bin thereof 26 down; that 1s, thel roof sheets may shift laterally under the clips 53. It will be noticed that aclearance space 53* is provided so as to facilitate relative displacement between the roof sheets 26 and -lfthe clips 53. Other similar clips 55'y each end of the transverse ca cli have a prong that reaches up over the outer 40. After the 53 and 55'are appli the fascia board' y Y 19 1s nailed or bolted in lace, thus covering vals - which securethe clips in place.

the lower ends of thec ips 53 and 55 a also covering the heads of the'spikes 54 It is to be observed 4that the arts are so assembledthat the upturned e ges 27-28 of the roofshee'ts 26 are iven Aafcertan amount of clearness (see Thus, it will be seen that each plate 26 is pivotally attached to the board roof 20V by means of the interlocking bosses 23 and 30,

and that it is possible to rotate each plate 26 ywithinfnarrow limits about the bolt 38, as an axis. It accordingly follows that if the carroof is strained from any cause, whether this is'due to sagging at the center orto diagonal stressesror any othercanse, such distortion of t-he board roof 20 will not be communicated to the metal roof sheets, 26.

Thus'it will be seen that Iv have provided a sheet metal-car roof which 'will not become broken and bent by reason of strains to which the roof support may be subjected.,

Of iiecessity,` in carrying out the aim stated in the foregoing paragraph, I have been obliged to provlde for relative disf lacement between adjacent roof sheets 26, gut it will be seen on referring to Fi 6 that this has been done without aforc any laccessjf'or rain water. The caps 32 a A0 fit over the adjacent edges of the roof sheets so as to practically exclude rain 'water.- vThen if any water should drive under ates 17.' Theseand no water' succeed in getting" between the of ad'acent roo sheets 26.

It will be o rvedt atthe blocks 37'with their sockets 30engaging the bosses 30 give sheets 26. The runni oard is supported bosses 23. Inasmuch as fthese arepivotal points in the displacement of the sheet roof beneath them, it willv be at vonce-appar- -does not obstructt-heelative movement of the roof sheets with respect to the board roof beneath. `The clips 53. and 55 at the edges of the roof simply keep thoseedges down in place, but do not reventa slight Figs. 3, 4 and 10. y This flashing consists of edge ies flat u on thetop of the board roof at its lateral e es, while the other edge lies againstY the en s of the boards'of the'roof lappi 19. T is flashing 80 is notched as indicated by the reference numeral 81, so as to accomm'odate 'the clips `53 and 55. It performs vent rain water from driving under the roof sheets rest beneath the clips 53, thus facilitating relative displacement of the roof, sheets `26 with respect to the Wooden roof l20beneath them. y
