To-all whom it may concern: V Be it known that I, JOHN PEARsON, a

citizen 'of the United States, residing at Chi cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Roofs, of which the following is -a specification, referencebeing had therein. to the accompanying improvements in car-roofs, the principal ob]ect of the invention being to provide an strain to the car-body and to expansion and contraction dueto changes in temperature.-

Another object is to provide an improved frame-work for car roofs whereby the care body is more effectively braced.

Another object-is to provide an improved in osition.

parent from the disclosure and claims.

The invention consists in thec onstructions'and arrangements of parts as herein after described and pointed out in the? claims, and as illustrated in the accompanying drawings, in which Figure 1 is a top plan view showing the improved frame-work of the car roof; Fig.

2 is a cross-sectional view of one side of the car roof taken on the line 25-2 of Fig. 3,

parts being broken away; Fig. 3 is a view partly in side elevation and partly in secconstruction for securing the running-board.

' ther objects of the invention will be ap-:

all asshown in Fig. 2.

The frame-work of 'theroo'f consists of'a ridge-pole 15, a series of carlines 16 'suitably spaced apart and extending the width of the car, and diagonal braces 17 extending from the four corners of the car to the inand the roof-boards 14 extend from the ridge to the side-plates in theusualinanner where they are 'flush with the crown-mold,

tersection of the ridge-pole and the central carline, as clearly shown in Fig. 1. Longitudinal braces or purlins 18 may be em-' ployed if desired to add structural strengthto the ear and to form supports, for the 0 roofb0ards between the ridge-pole and the" diagonal braces, being fastened to the under, sides of the car-lines by bolts orv other suit- 2 able-means. The carlines' 16 are located above the ridge-pole'and diagonal braces as shown in Fig. 1,'and at their crossing and. meeting points are seated in gains in the braces and ridge-pole, as'clearly shown in Fig. 4

If desired, the carlines and braces may-befurther, connected to ether at their crossing and meeting points nections are readily made as the" carlines referably consist of Lbeams, as shown in *igs. 2 and 4, and the bolts may pass y any suitable means, such as bolts 19 shown in Fig, 4. These conthrough their flanges, but it is of course to,

be understood that any other suitable form may be used forthe carlines, such as angle" irons, T-irons, or deck-beams, with any suit able connections if desired, without in anyway departing from my invention.

- By having the diagonal braces rigidly secured to the body-carlin es the bracing aci tion or effect thereof extends from each carline .to adjacent ones, and the entire roof structure is braced to reduce straining or twisting action to a'minimum. By havingthe. body-'carlines overlying the ridge-pole, braces, and purlins, the latter and the roofthe carlines.

"The carlines 16 are suitably connected at their ends to the'walls of the car-body,'a'n das a convenient means of making this connection I provide suitable clamp-plates 20, eacho'fwhich is seated in a gain or mortise in 100 materials are all supported and carried by lines 16 pass through theboards and their crown-flanges ext-end above the upper .face thereof. This extension may be conveniently utilized for the purpose of holding the running-boards in place.. As shown in Fig. 4, a cleat 21 of suitable length extends parallel with one or more of the carlines l6, and is adapted to support the running-board.

When the carlines are in the form of I- beams, as'shown in Fig. 4, the cleats extend at one edge under their exposed crownflanges and when the running-boards are secured to the cleats by any suitable means, such as the nails 22, it is obvious that the cooperation'of .the cleats with the flanges of the carlines serves to hold the runningboards in place; It is of course apparent that the cleats need not be provided for each of the carlincs, as they may be associated with one or more of them, and that they may be provided upon opposite sides of alternate or separated carlines.

When the carlines are in the form of angle irons, as shown in Fig. 9, the cleats 21 may be arranged in substantially the same manner, it of coursebeing obvious that the upper flangesct some of the carlines may then be oppositely disposed in order to provide for the opposite disposition of the cleats so as to holdtherunning-boards against movement in either direction. I

WVhen the ca-rlines are rovided with upper flanges it is preferab e to undercutthe cleats, substantially as shown in Figs. 4 and 9,. so that the shoulders formed thereon will cotipe'rate with the edges of the flanges,

while their upper faces will be flush with the upper faces of-the crown-flanges, although it s obvious that the cleats may be in the formof plain strips and the running-boards may be grooved or channeled to fit over' the upper flanges of the ca-rlines,

The metallic portion of the roof consists of a series of plates or panels 23 of any suitable material, such asgalvanized metal for example, which lie upon the roof-boards between the carhnes and-extend across the width of the car. The plates or panels are flexibly secured to caps which are associated with the carlines, each cap extending along the length of its associated carline across the width ofthe car and being preferably in two sections-abutting at the center: .The" joint thus formed between the sections of the caps may be j pI'Qt ECtQd in any suitable manner, and it is obylous that the cleats 21 to which therunnmg-board. is secured will furnish a convenient means for this purpose, theylbeing'preferably located at both sides of each carline, and lapping past the abuttingends of the sections of the caps. The caps are provided with upper horizontal portions 24 ,of suflicient width to extend across the carpanels 23, and forthis purpose I prefer to providev such joints that the panels or plates may be laid in place between the carlines and the associated caps may be interlocked therewith by telescoping their side edges into the plates-from the end while sliding them in place on the associated carlines.

This may be accomplished in a number of different. ways and forthis purpose I provide one side of each cap with a horizontal pocket 27 and the opposite side with a vertical pocketv28 adapted respectively to receive horizontal and vertical flanges on the associated sides of the panels, as shown in Figs. 3 and 4. The vertical pocket 28 is formed by extending one side of the cap beyond the return bend downwardly'and then upwardly; and the pocket 27 isformed by extending the other side of the cap inwardly and then outwardly, a verticallip or curtain 29 being preferably formed to render the vjoint more effectually water proof. 1 The I shown at- 30, andthe edge 'of one of the upturned sides is provided with a horizontal flange31, while the edge of the opposite side is provided, with a vertical depending flange'32., The panels are laid'in place between the carlines, and their flanges are then inserted in the ends of the pockets of the caps and telescoped therewith as the sections of the latter are slid in place upon the carlines.

The form of joint between the caps and plates may be varied without departing from my invention. For example, the pockets on both sides of each cap may be formed in the same manner as the vertical pocket 28, and

the side edges of adjacent panels may be pro vided with, flanges 32 to interlock therewith,

as shown in Figs. 8 and 9. v

The joints allow the panels to move. inde pendently of each other-and with suflicient elasticity in case of straining of the carbody, and any panel may be easily and readily rernovedand replaced in lcase repairs are iietessitfiy,'whi.le they also may be nested one within the other for 'convenieg 'jte of shipping. The inter-connection of 'ihe plates;

' ably secured.

caps and carlines serves to securely hold'the parts of the roof together, and to prevent the ingress of water, snow, sparks, etc., while at the same time the panels are free to move upon each other or have sufiicient play to allow them to take up any strain or movement caused by the action of the car body without buckling or fracture at their joints which isthe initial point of breakage in most metal roofs.

The ends of the anels or plates are downturned, as shown 1n Fig. 2, wherethey lie in a rabbet formed longitudinally in the upper edge'of the crown-mold. The ends of the plates are downt-urned and rovided with-double return bends 33, with their edges overlyin the outer face ofthe crownmold. The ra bet'in the crown-moldpermits the plates to have suflicient play due. to any movement of the car-body, and their downturned edges form tight connection or joints. The ends of the plates are preferably held close down in the rabbet of the crown-mold, and for this purpose I preferably rovlde means which does not interfere -w1th any play or movement of the plates.

As shown in Figs. 2 and 3, I provide suitable brackets 34, secured to the crownmold and projecting above and over theupper edge thereof. These brackets "are disosed along the sides of the car at intervals. etween'the carlines, and each bracket is provided with a passage 'or-opening in its upper inwardly projecting portion adapted to receive an arched link 35, .whose ends bear upon the panels or plates. The links.

have free rocking movement in their brackets to yield to any movement of'the panels due to any strain to .the car-body. The outer ends of the end-panels are merely bent over the end-plates l1 and suitf The ends of the carlines are'recessed or cut away in order to receive the upper portion of the crown-mold where it extends above the side-plates, as shown'in' Fig. 2.

The ends of the carlines are provided with hoods 36, and I show a suitable construction for this urpose in Figs. 5, 6 and; 7, although of course the .details may be varied without. departin from v my invention.

Each of the hoods is preferably ofmalleablemetal, and in general outline is U-shape in both vertical and horizontal cross-section, its contour being shown in Figs. and 6, whereb it is adapted to fit over the corresponding ca line with its associated capwhose ends are. bent down over the ends bf the carline. The open mouth of. the hood is adapted to he slipped over the end ofthe carline and. secured in position b any suitable means such as a bolt 37pass1ng through the side walls of the hood and the we of the carline, it being understood that the panels beneath the hoods.

23 are recessed or cut back along their upturned sides sufiicie'ntly so that they are free from the bolts, as shown in Fig.6.

Theouter portions of the hoods pass down I have heretofore stated that the form of the carlines may be varied without departing from my invention, and in order to illustrate the organization when some forms other than I-beams areused, I have illustrated two modifications in Figs. 8 and 9. In Fig. 8 the c'arline is shown in the form of an inverted T-iron, and in Fig. 9 in the form of a channel bar.

A strip 39 may be employed if desired to prevent the horizontal pocket from sagging under thestrain of the associated panel. It is of course obvious'that the fastening for the'ends of the carlines may be varied; for example, the clamp-plates 20 may be riveted or otherwise secured to the flanges of'the carlines and thensuitably secured to the side-plate 11.

By providing a construction by which the plates or panels may"be inserted in place from above I am enabled to utilizepanels wh'ich'extend' the entire width of the car,"thereby reducing the cost of assembling the parts and also obviating all of the objections and defects of fracture at the ridge-pole incident to a'joint between sections of panels each extending only half of the width of the car, or to bending a panel at the ridge-pole when inserted from either.

side across the width of the car. At the 1 same time theconnections of the roof plates or panels with their caps and flexible end links allow s'ufiicient play or elasticity in all directions to avoid danger of buckling the panels or breaking of joints due to expansion or contraction by reason of changes in temperature orto any movementscaused by.

the straining of the car-body. The provision of carlines lying above the ridge'pole and braces'enables me toutilize these carlines for the purpose of furnishin suitable supports for the caps, whereby te plates .or panels are accurately and securely held in place, and also for the purpose of holding the running-board in place.
