ROOF-FRAME FOR CABS.

Specification of Letters Patent.

' Patented May 14, 1912 Original application filed March 29, 1910, Serial No. 552,131. Dividedand this application filed March 7,

Cars, of which the following is a specification.

My invention relates to improvements in car roof frames and more particularly to a carline and suitable means for attaching the same to the rest of the roof frame structure. I This application is a dlvision of my copending application Serial No. 552,131, filed March 29. 1910. for a car roof construction.

The principal object of my invention is to provide an improved car roof frame of simple. strong and inexpensive construction.

Another object is to furnish, in connection with the said roof frame, a well braced carline, the construction of which requires little work either by machine or by hand.

One of theobjectsis to produce a carline comprising a rolled bar of standard form for a body in connection with a pair of well braced cast metal forked ends having thoroughly strong and rigid means for fastening the said parts together and amplemeans for attaching the carline to other parts of the roof frame. While my roof frame is in some respects similar to the frame disclosed in my Patent No. 955,544 of April 19, 1910, I aim to greatly improve the carline therein de scribed.

These and other objects will be more fully set forth and made apparentin the following specification and claims in connection with the accompanying drawings showing a preferred embodiment.

Figure 1 is a plan view of a portion of my car roof with a part of the said roof broken away to show more clearly the framework and the relation of my improvements thereto. Fig. 2 IS a side elevation of same with portions broken away. Fig. 3 1s a transverse vertical section across the roof on theline 3--3 of Fig. 1. Fig. 4 is a longitudh nal vertical section of a portion of the roof taken on the line 4-4 of Figs. 1 and 3. Fig. 5 is a detail in section showing the relation of the end of a carline to one of the side plates. Fig. 6 is 0. pers ective view of my improved cat-line assein led complete and Serial No. 612,797.

ready for installation in a car roof frame. Fig. 7 is a cross section of the same on the line 77 of Fig. 6. Fig. 8 is a sectional detail showing a modification of attachmentof my carline to the side plates. Fig. 9 is a sectional view crosswise of the ear showing my improved carline attached to a steel side plate, which in this case is a channel bar.

.Fig. 10 is a sectional view showing my 1111;

proved form of car-line attached to a steel slde plate which has the form of an angle bar. Fig. 11 is an underneath view of'the' end of one of my carlines showing its connection to a steel side plate. Fig. 12 is a perspective view showing .a carline end similar to that shown. in Fig. 11, but without connection to a side plate. This view shows clearly how the horizontal flanges are cut away from the extreme ends sons to enable the vertical flanges to fit closely to the side plate. Fig. 13 is a' cross section showing a modification in which an I-beam is used for the middle portion of the beam, the section being at a point where the'said I-beam is riveted to the cast metal forked ends. .Fig. 14 is a cross section of another modification in which two angle bars are u;-sed.for the middle portion of said beam, the bars being placed together edge to edge and the section being at the point where the angle bars are riveted to the forked end portion.

In all drawings like reference numerals apply to like parts.

In the accompanying drawings I have preferred to show my improved carline in connection with a roof framework which supports metal roof plates beneath the usual wooden roof.

The framework of the car roof comprises the usual side plates 16, placed longitudinally of the car, end plates 17 placed transversely of the car, the purlins 18 and the ridge beam 19, the latter members lying lon-' gitudinally of the car. Transversely ar- 'portion 20"and forked end portions 21. An

important feature of these carlines consists in the making of'the body portions of rolled material while the forked ends may be made of cast material. Imthe forked end portions 21 I prefer to use niateriai known as malleable iron. The forked end portions are secured to the body portion by suitable. rivets 22 or other substantial means.

.. The-hadyo-pertion 20 is securely attached to .t-hc'ridge beam 19 by thebolts 32, and to the.

gextendingflanges of these end portions are embedded' in suitable grooves in the inner side'of the side plates. -These; carline ends 24 are firmly secured to the side lates by the yokebolts'2'6, as shown cleary in.

Fig. 1.- This method of embedding a portion of the end of the carline inf the side .plat'e is intended to be used in connection. with wooden side plates only. The" method of attaching the carlines to steel s ide platesis "hereinafter described.

The body portion 20. of the carline is' preferably of channel form, having a web 27 and downwardly extendingflanges- 28.

The web portion 27 ,is attached to the frame" members 18 and 19 by suitable bolts. The

forked end portions 21 each comprises a ,pass that attach it to the main channel and flanged body 29 having downwardly ex-' tending flanges 30 through which the rivets 1 two divergent arms that extend outwardly and are attacliedyto the side plates. The

. said body portionis given such a size and form as to cause it to fit snugly around the end of the body portion 25, as shown most clearly in Figs. 4 and 7. I The body'portion of the carline may also be made of an 'I-beam 33, shown in cross section in Fig. 13. In, this case the forked end portion must have a specialform at the Fig. 14. I

point where' it engages the bar, as shown at "53 in-Fig. 13. y I

Another convenient form, if preferred,

comprises twoangle, bars placed edge to edge. for a body portion, fassh'own at 54 in Fig. 1-4, in which "a cross section is represented. In'this case a regular form of a forked end piece may be used, such as already described and as shown at in The purlin 18 may be recessed, as shown at 31 on Fig. 4, to receive the body portion '29 of the forked ends. The carline may be attached to the ridge beam 19 by the bolts 32, the spacing block 45being provided to preserve the same spacing at the center of the car as exists at points where the pur- Yea lins 18 are placed. The carline is 'ven a bent form, which permits it to con orm to the general slope of the roof. There is preferably a short portion 34 which lies horizontally andmeets the sloping end portions 35 at the bends 36 where the outer portions incline downward. Inthe form of end -21, and also ,to the car roof which I have preferred to show in connection with my improvements, the usual fascia-board 37 is used. The yoke bolts 26 pass through the fascia board and are socuied in positionbylthe washer plates 56 and the nuts 38.

The corrugated metal, plate 39 lies immev diately above the side plates 16 and the purlin 18 and is embedded in,,thc ridge beam 19 atits'inner edges. Its inclined lateral edges are embedded in. the sub-earlines 43. Innnediately above this --corrugate-d metal plate. are placed the sub-pun lins 40, .upon which are placed the' roof boards 41. The roofboa'rdsare also spaced from the corrugated plates 39 by the supplementary ridge members 42 and the sup. plementary side plates 44, the latter being located directly above the main side plates 16, .as shown in Fig. 3. The sub-carlines 43 serve'for a number of purposes comprising means to. support the sides of the corrugated plates 39, also to space the purlins 18 from the,sub-purlins.40,- likewise they serve toseparate plates 16and 44 and also to separate .the ridge- members 42 and 45. The diagonal corner braces '46 are attached to the side platein similar manner to the forked end members or plates'17. v

It will be'understood that my improved carlines are adapted for all kinds of roofs, although I have illustrated them 'in connection with a roof which'is made up of a metal roof Within the usual wooden roof;

' My improvedcarlines are adapted tov any form of'roof structure in which said roof must be supported by members arranged transversely of the car body, and in which said members are subjected todia 'onal stresses. The forked end portions 0? my improved carlines very readily transmit the said diagonal stresses from the side plates to the purlins and to the inner portions of the framework.

I have thus far described my improved carline in connection with wooden side plates only, as shown at 16 in Fig. 3. In order to permit its use in connection with metal plates I have provided suitable means, as disclosed in Figs. 9, 10, 11 and 12. In Fig. 91- have shown a sectional detail in' which a channel bar 47 is used as a side, plate. The end 48 of one of the forks is modified sufiiciently by cutting off a portion of a horizontal flange to permit the vertical flange to lieclose against the web of the said channel bar, as shown. at 49. The detail of this construction is more clearly shown in'perspective view in. Fig. 12 and also in Figrll. The end of the vertical flange 50, which remains after drilling off the end of the horizontal flange, may be riveted to the web of the. channel bar, as

shown inFigs. 9 and 11. In Fig. 10 I have further illustrated the use of my carline in .connection with metal side plates. In this case an angle bar 51 is used as a side plate against which the forked ends of the carline are riveted or otherwise attached, substantially as shown in Fig. 11. In Fig. 8 I have shown a transverse sectional detail in which the end of the carline is attached tor a Wooden side plate by means of plain bolts 52 in place of the yoke bolts hereto referred to.- Otherwise the carline is attached to the Wooden plates, substantially as. described in the first part of my specification, the horizontal flange 25 being placed in a suitable groove cut in the side of the wooden plate. I do not'in this application claim broadly a car roof construction comprising metallic carlines having .an arched form sloping downwardly from the central part of the car toward the sides thereof, the end parts of the carlines being bifurcated and the bifurcated. portions diverging toward the car sides, although I disclose herein a speeific embodiment of such generic invention, inasmuch as such generic invention is broadly claimed in my Reissue Patent No. 13,297, granted October 3, 1911, the application for which was copendin'g with the original application of which this present application is a division. 4 I Having thus described my invention, what I- claim and desire to secure by Letters Pat entis:.'-. .1. In roof construction for railway cars, a carline comprising a central member and end members secured to the ends of the central member, each of said end members being divided longitudinally and spread diagonally apart.
