CAR ROOF.

Application filed May 31,

The invention relates to what are known as rigid all-steel car roofs, it being understood that wood may be employed in some cases for certain of the frame elements.

The invention has for its principle objects to lessen the cost ot the root as an entirety, and to simplify the construction oit the same and reduce the cost of applying it to the roof frame; also to enclose by the root sheets all of the frame-fastening devices; also to Vunite the root sheets rigidly and immovably with the carlinesi so that the sheets will not be subject to tearing under strain. i

V'Tith such objects in view, as well as other advantages which may be incident to the use et the improvements, the invention consists in the parts and combinations thereoi1 hereinafter set -torth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportions and arrangement without depart-ing from the nature and scope of the invention.

In order to make the invention more clearly understood there are shown in the ac companying drawings means for carryingthe same into practical effect, without lim-- iting the improvements, in their useful applications, to the particular constructions which, for the purpose ot' explanation, have been made the subject of illustration.

Fig. 21 is a vertical sectional view similar to Fig. 18, but illustrating the application ot the root to a wooden side plate.

Fig. 22 is a side elevation ot the same.

Referring to the drawings, 1 indicates the side plates of the roof frame. These are ordinarily or preferably of steel, but may be of wood as shown at 1a in Fig. 21. In the former case the side plate is or may bc an angle iron having a vertical web 2 and a top flange 3, the latter somewhat inclined to correspond with the pitch of the root. Attached to the side plates 1 are end plates 4, which may be of steel of angle sha e, as shown in plan view at the left end o Fig.

1 formed with a top flange 5 and vertical web 6, theends 7 of the latter (Fig. 1) being bent into parallelism with and riveted to the webs 2 of the side plates.

AThe carlines are indicated at 8 and are of steel of inverted channel shape, formed with top webs 9, side webs 10 and outstanding bottom flanges 11 (Fig. 17). These carlines extend from side of the roof and are secured at their ends to the flanges 3 of the side plates by rivets 12 (Fig. 18) or by bolts 12a (Fig. 21), passing down through the widened ends 13 of the flanges 11 (Fig. 1).

The contour of the carlines from end to end is suitably arched or hipped to give the desired shape to the roof, and their webs 10 are downwardly inclined and flared away from each other.

The carlines may carry and be strengthened by sheet-supporting purlins 14: and a ridge pole 15, these parts being` preferably but not necessarily of wood. The purlins are attached at their ends to the flanges 5 of the end plates by bolts 16 (Fig. 1), and to the -webs 9 of the carlines by bolts 17 (Figs. 1 and 16).

The ridge pole is similarly attached to the carlines by bolts indicated at 18 (Figs. 1 and 15) and to the end plates by bolts 19. An end fascia inay be used as shown at 2l (Figs. 1 and 10); and with wooden side plates a side fascia 25 (Figs. 21 and 22).

Such being the preferred or a suitable structure of roof frame, the sheets or plates to be fitted and secured thereon*J to malte the roof sheathing will now be described.

Y The roof sheathing consists of a series of intermediate roof sheets 20, each extending between, engaging and supported by a pair of the carlines, and of end sheets 21 similarly covering the spaces from the end plates to the end carlines. These sheets, each eX- tending` across the car from side plate to side plate, lap over one another shingle fashion, proceeding from one end of the roof to the other, and one of the end sheets under-laps its contiguous intermediate sheet and the other end sheet over-laps its contiguous sheet. Fach intermediate sheet 2O is bent along' one of its -edges, to form a channel 22 which embraces and fits a carline; and is similarly bent along its other edge to form 'a channel 23 which embraces and fits outside of a channel 22 of the neXt sheet when the latter is in place on a carline (Fig. 17). The over-lapping channels 23 are consequently, if the lsheets be shaped to the best advantage, a little wider than the und`er-lapping channels 22, by

' about twice the thickness of the metal of which the sheets are made. Each of said roof 'sheet channels flares downwardly to correspond with the said vshape of the car-V line side webs 10, and from end to end,

across the roof is shaped to fit the arched or other contour of the carline (Fig. 2). The end sheets are similarly formed along one edge only, with a channel (Fig. 3), one end sheet having an under-lapping channel 22 and the other an over-lapping channel 23. Along these channels and at a little distance therefrom the bodies of the roof sheets are upwardly bent, recessed or embossed, as shown at 26, for a distance equal to the thickness of the carline flanges 11, so as to enclose said flanges and also have the under surfaces of their main portions at the level of the under sides of the cai-lines, and in contact with the tops of the side plates; and with the ridge pole and purlins when the last mentioned elements are comprised in the roof frame. It may be here stated that by making the roof sheets of thicker metal, of self-supporting strength,

the ridgepole or purlins or both may be dis-V pensed with, and the invention is not limited, in all of its applications, to the use therewith of a ridge pole or of purlins or of both of said frame elements.

In a roof of this rigid character, and especially when purlins or ridge pole or both are dispensed with, it is of great importance to secure the roof sheets to the carlines by an attachment of a strong and unyielding charaeter, and which will not cause disruption of the'roof sheets at the points of attachment when strains are imposed on the sheets; and for these objects it is further preferable to attach the roof sheets to the carlines at points near the general level of the roof. The present invention obtains these results to a materially improved degree and by improved means, as will now be described. 29 indicates the roof sheet clamps (Figs. 13 and 14) formed of metal having suiiicient resiliency to yield a little so as to apply the securing pressure gradually and evenly and yet so as not to release the roof sheets by any pull of the latter. These clamps, which are of greater rigidity than the roof sheets and thus provide for firmly clamping the latter' to the carlines, are formed to embrace the carlines, and the

channels

22, 23 of the roof sheets thereon, by jaw elements 30 connected by a top part 31. rEhe inner faces of the `iaw elements or sides 30 of the clamps diverge downwardlyY somewhat more acutely than the sides of the cooperating carlines, thereby enabling the roof sheets to be securely clamped to the carlines near the gen eral level of the roof. rlhe top of the clamp 29 is formed with a bolt perforation 32 which latter is or may be surrounded by an upward einbossment 33 of lthe top. rlhe manner of application of these clamps is shown best in Figs. 11 and 12. In these two figures the clamps are essentially the same, the securing bolts 34E in Fig. 11 being elongated upwardly and provided With top nuts Cal 62 which extends through an end bracket part 63 of the cover plate and into the end fascia. ThisV cover plate closes an interstice in the construction caused mainly by the flanges 7 of the end plate passing under the flange 3 and the top flange 5 of the end plate being arranged at a level with the top of the side plate, and the cover plate prevents any rain being dashed into the interior of the car in heavy storms.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing any of its material advantages, to form hereinbefore described being merely a preferred embodiment thereof.
