tions of the end plate, ridge pole and end sheathing. Fig. 9 is a vertical transverse section along the line 9 of .l igalfl showing the con'iplete roof including the runninghoard and embodying the frame shown in Fig. 11. Fig. 10 is a vertical longitudinal "W15 roof framework suitable to support and sea vertical cross section of the roof frame m cure an ordinary freight car root. only along the line t) of Fig. 10 and shows a -Another object. is to i rovide a strongly carlinc of metal and purlins and ridge pole braced, light Wight, 't'reiht car roof frame made of wood alone. i .w t truturel I t in all the views like reference numerals 20. St ll another! object is to'i novide a light refer to like parts.

Another object is to provide a noirracking and strong 't'reight car root .fraine 'suitahle afor/use in connection with the peculiar jointed metal plate rooting descrihcd in my latcnt NlLiiiihlti'iof April 5, 1910.

Fig. 2 is a pcrspiaztive view of one ot' the several braced metal cross hars each of which is known as a carline. Fig. 3 is a i perspective view of the end i'astcning of one (40. of thefmu' similar ln'anches of a carlinc. Fig. 4 is a cross" sectional view of the root section along the line 10 of Fig. 9. 11

Referring to the preferred embodiment hown in Fig, l, the roof structure consists generally of a closed covering mounted on a structural iron framework.

The covering" -25, desire to provide a structural metal car roof here shown consists of sheet metal plates. 1% frame of great strength and durahility. The plates at the end are marked 47 and the These objects. and others will he made ap t l w n o plates H3. thesaid plates all parent in the following specification and ;lf -i d ogether by upturned edges and claims, takenin connection with the accom tilt h-1' Mltl j Sheath-5 8 and 3O panying drawings showinga preferred cup sprrtneiy. cssrut vas per my P 'C ing striurture of the carlinos is one principal features of my invention. One of these carlines is shown in detail by" Fig. 2, in which 1 is the complete carline, 9, either one of two similar and complementary component angle bars that together constitute a rarlin e. J the top flange of bar 2, 2" the side tiange olhar 2, -i the horizontal middle portion of hat" 2, and .5'is one ot a group oi. clamping elements, preferably rivets, through the flanges 2'. to fastentogether the two complementary bars 2 at the central portion 4 of the bars that thus assembled constitute areal-line. The downwardly in frame on the line 4: of Fig. l with the eoven ing and running hoard removed and shows particular] y one of the side plates, one. oi the 45 carlines, the iridgc pole, and part of the longitudinal root iiiirs known as purlins. The ridge pole and purlins here shown are each composed of a channel iJiiI inclosing a.

wooden tiller-block. Fig. 5 is a cross sec" 50 liional view similar to l ig. -i except. the inverted position oi therii ige pole and slight minordetails. Fig. (3 is also a cross sectional view similar to Fig. t except the inverted position of the ridge pole and pur- 56 has, which in this themost preferred eniturned transversely and toward the complementary member. The point where the -.flange ends 8 and 9 bend from alinement 'with the adjacent bar body and divergent.

from each other is'marked 10. The flange end 8 is perforated by a hole 11 and flange end 9 is provided with holes 12. The inclined portion of flange 2 is provided with holes 13 and the horizontal part of flange 2 is provided with a hole 14. These holes are adapted for engagement with bolts, rivets or the like for fastening to other parts of the frame and roof. i

The main outer framework for the roof consists of two side plates 16 and two end plates 15 fitted together in rectangular shape. On the upper side of each side plate are furnished filler-blocks 17 so as to provide an inclined upper surface to engage the roof covering. These filler-blocks are provided withjsp ces 18 to admit the flange ends 8 for fas ening to the side plates 16 by means of the/ bolts 3, as shown by Fig. 3. ,"Each fillergblock, 17 has a flat horizontali inder side,21 to engage the top of the side p .ate 16, an inclined upper surface 20 to engage with In Fig. 1 bolts 22 are shown for fasteningthe roof and a vertical inner face 19.

the flange ends 9 to the plates16. The bolts 3. are also here shown. The ridge pole 23 is shown centrally located and supported on the carlines 1, where secured by the bolts 45.

- -In' this embodiment shown by Figs. 1 and 9 these bolts 45 extend downward through the running board 24, saddle block 25, ridge sheath 49, ridge pole 23, and carline flange 2'.

I prefer generally to use separate means 42 for fastening the ridge pole to the carlines as shown in Figs. 4, 5, and 6 and then the bolts for fastening the running board, saddle block and ridge sheath to the ridge pole ma be distributed along the ridge irrespective of the carlines. The purlins 2 9 are suitably distributed on each side of the ridge pole and fastened by suitable means such as bolts or rivets 30 t0 the carline bars The ridge pole 23, which in its preferredembodiment, as shown in Fig. 6, consists chiefly of a channel bar, has its side flanges 40 cut away at the ends and the end 43 ofits web 39turneddown at the point 37 over the end plate 15 and secured by suitable means,

such as bolts through the holes 44, shown in Fig. 4, the end sheathing 38 being recessed to receive it as shown in Fig. 8. The purlins are also formed and secured'at their ends in a similar way. Several embodiments of ridge pole and purlin construction are shown by Figs. 4, 5, 6 and 11, Fig. 6 showing the one I prefer.

The ridge pole and purlins shown in Fig. 6 each consist of a metal channel bar only and in Fig. 11 they are made of wood only while in Figs. 4 and 5 theyeaeh consist of a channel barcontaining a filler block of wood.

In Fig. 4 one end of a carline 2 is shown attached to the side plate 16 and supporting the wood-filled channel bars constituting the 'purlins 29 and ridge pole 23. Each purlin channel 31-32 is shown with its flanges 32 cut away and its web 31 turned downward at the end 35 and rovided with perforations 36 to engage'wlth means for fastening to the end plate 15 in a. manner similar to that by which the web of the ridge pole channel is turned downward at its end 43 and provided with perforations 44, for bolts or the like as aforesaid. The purlin fillerblock is marked 33 and ridge pole fillerblock 41.

' Fig. 5 is similar to Fig. 4 except that theridge pole is inverted so that its channel flanges turn downward instead of upward.

The embodiment of Figs. 6 and 7 diifers from those of Figs. 4 and 5 only in that the ridge pole and purlin channels are all devoid of filler-blocks and all have their flanges turned downward, the said flanges being trimmed away at the points of engagement with the end plates and carlines so as to give the channel webs direct bearing on the cross elements. The flange 2 of the carline then fitsin the notches 34 in the purlin flanges 32 and in similar notches 56 in the ridge channelflanges 40.

Fig. 11 showing the use of plain wooden purlinsand ridge pole is similar to Fig. 4 except that all channel bars are omitted. This provides lightness of construction where the greater strength of channel irons is not required. a

Figs. 9 and 10 show longitudinal and transverse sections respectively of the roof assembly. Fig. 9 shows the roof framework of Fig. 11 in conjunction with the sheet metal roofing and running board as described in my previous patent aforesaid. The metal roof' plates 46 with their upper inward edges 46 hooked and nearly abutting and with their lower outer edgesresting on theside plate filler blocks 17 are shown in Fig. 9. The said inner hooked edges 46 are locked by means of the ridge sheath 49. The side edges 46 are also similarly hooked and locked by the cross sheaths 48. The outer end of 'each cross sheath is secured by a downwardly turned end 55 fastened to the side of the car bya bolt 54 as shown in Figs. 1 and 9. Each end 53 of the ridge sheath 49 is likewise turned down and fastened by a bolt 53.

All-outer edges of the roof plates 46 and strips across 47 adjacent to the edge of the roof are clamped in place by'the clips 5051' and 50'T51 the latter being used at the roof corners. Each clip has tongues 51 to engage the roof plates and a main downwardly turned part 50 or 50' respectively equipped with screws 52 ,or the like to engage with the side of the car.

A running board is provided as shown in Figs. 9 and 10. v This consists of the several 24 attached to saddle blocks 25 placed the ridge sheath 49. Each block is fitted on its under side with a middle surface 27 to engage and rest on the ridge sheath 49, and with inclined surfaces 26 to engage with and rest on the cross sheaths 48.

Bolts 45 are provided to extend downward ;.through the center of the running board 2-1,

the saddle block 25, sheath 49 and ridge pole '23, thus to lock the parts securely together.

. While .I have herein shown and particularly described some embodiments of m vention, I ,do not wish to limit myse f to the precise constructions as herein shown and particularly described as many modifications may be made b those skilled in the art without departing rom the spirit of iny said -invention. 4
