Application filed January 6, 1925. Serial No. 886.

This invention relates in. general to .im provements in car roof construction, and more particularly to improvements 1n the all steel rigid type of car roofs for freight carsand the like. 7

Objects of the invention are the provision of a car roof construction permitting rapld and easy assembly of the roof on freight cars and which when assembled will be water tight and rigidly secured in place; the provision of a construction in which the parts will not become loose as a result of constant vibration or twisting and weaving motions of the car; .the' provision of a conv struction in which a wedge clamp may be used so that as the wedge key is positioned it will draw the clamping portions tightly down on the parts, and hold the parts in such clamp tight engagement; the provi- ZQ sion of such a roof which may be formed of simple parts easily and inexpensively manufactured and which when assembled will not require frequent repair and .replacement, and such other objects and advantages of the invention as may be found to obtain in the structure, hereinafter de scribed and claimed.

In the accompanying drawings forming a part of this specification, and showing,'for purposes of exemplification, a preferred f01'I]1 and manner in which the invention may be embodied and practiced, but without limiting the claimed invention specifically to such illustrative instance or instances:

Fig. 7 is a vertical cross-sectional view taken on the line 7-7 of Fig. 1.

Fig. 8 is a perspective view of one of the split tapered wedges.

Referring to the drawings the invention is there shown as embodied in the all steel rigid type of car roofs, having longitudinally extending Z-bar side plates 10 consisting of a vertical Web 11, a lower outwardly extending horizontal flange 12 and an upper inwardly extending horizontal flange 13. Extending longitudinally of the car and arranged between the side lates are the usual wooden purlins 14 and ridge pole 15. Extending across the car from side plate to side plate are inverted channel shaped carlines 16, said carlines being arched to conform to the pitch of the roof and consisting of a substantially flat top web 17 connecting a plurality of depending outwardly flaring sides 18 that terminate in outwardly directed lateral fla'nges .19. At each eaves end the depending sides decrease in height and merge at 21 into the lateral flanges 19 and at such eaves ends the lateral flanges are depressed at 22 and are gradually widened toward the eaves as at 20 to form a seat for the carlines at the side plates, said seat resting upon the upper flange 13' to which it is rigidly secured by rivets 23. The spaces between the side 7 plates and the carlines are closed by intermediate roof sheet sections-24 and end roof sheet sections, said roof sheets extending 'across the'car from side plate to side plate to which they may be rigidly secured by bolts 26 passing through the depending eaves flange 27 of the roof sheets and the vertical web of the side plate. edges of the roof sheets are pressed up- The side.

wardly-at 28 to fit over the lateral flanges 19 of the carline so that the main body 29 p of the roof sheets may rest upon, and be supported by the longitudinally extending purhns and ridge pole when such purlins and ridge pole are used in the roof structions 20 of the carlines. The side edges of said'roof sheets terminate in inverted channel shaped portions having-'9. substantially flat top web 31 connecting the depending outwardly flaring sides 33 whose lower portions terminate adjacent the lower portions of the sides of said carline, said inverted channel shaped portions being shaped similarly to the inverted channel portion of the carlines so that the adjacent sides of adjacent roof sheets are arran ed in lapped formation over the inverted channel portion of the adjacent carline to fully enclose and tight-l embrace the carlinewhen assembled, as SlOWD in Figs. 4 and 5.

The eaves ends of said side portions of the roof sheets also decreasesin height as indicated at 32 and the adjacent depending eaves flanges of adjacent roof sheets are' lapped at 33 and such lapped eaves flan es are rigidly held together by bolts 34 that pass therethrough and through the side plates.

In order to secure the inverted channeled side portions of the roof sheets immovably down on the carlines there are provided clamps 35, in the present embodiment illustrated as pressed steel clamps, said clamps consisting of a top web 36 connecting depending outwardly flaring sides 37 that extend down to the lower portions of the sides of the carline and the sides of the inverted channel sides of the roof sheets. The inner faces of the flaring sides 37 of the clam s diverge downwardly somewhat more acutey than the sides of the cooperating carlines, thereby enabling the roof shwts to be securely clam ed to the carlines near the general level 0 the roof.

The top webs of the clamps are pressed upwardly at 38 and'each web is apertured as indicated at 39. The web and sides are strengthened by an'outwardly extending rib 41 running from the pressed out rtion of the web to near the lower edge 0 the sides of the clamp. The webs of the outlines are apertured to correspond with apertures 42 in the webs of the inverted channel sides of the roof sheets. i

A depending slotted member .or slotted bolt having its upper portion of reduced diameter as indicated at 43 is rigidly secured to the web of the clamp by inserting the reduced portion through the aperture in the web so that the depending member of the bolt is arranged between the sides of the clamp, then riveting-the upper end of the bolt down on the outer face of the pressed out portion of the web of the clamp. The opposite end of the bolt terminates in a downwardly tapering portion forming a drift for entering the apertures of the roof sheets and carlines so as to cooperate with said sheets and carline to enforce shiftin of the sheets to proper assembled position w en the clamp is applied. The lower portion 44 of the bolt is provided with an elongated slot 45 extending from near the portion of carline thereby pro'vidin reduced diameter to near the lower end of the bolt. The lower end or face of the slot is curved or inclined in opposite directions as indicated at 46 to facilitate entrance of a wedge 47, said wedge being formed from a strip of metal bent upon itself at 48 to U- shape to form a split wedge. The wedge is tapered toward one end and the greater portion of one longitudinal edge, the upper edge 49, contacts with the bottom face of the web of the carline, as indicated at 51 in Figs. 3 and7, the remainderof said upper edge 52 of the wedge being downwardly inclined as indicated at 53.

The greater portion of the length of the other longitudinal edge 54, the lower edge, of said wedge is inclined with respect to said upper edge when positioned in the slotof the bolt and the remainder-of said edge is inclined upwardly as indicated at 55. The increased taper at one end permits the key to be entered in the slot of the bolt while extending at an angle to the plane of the face of the carline with which the key contacts when in assembled position; thus enabling the key to be readily brought intojinitial cooperative relation with the slotted bolt and facilitating its driving. The driving of the wedge in the slot draws the clamp down towards the carline so as to cause it to have wedging cooperation with the lower parts of the carline and roof sheets channels, thereby securing the latter by a strong pressure immovably to the carline. After the wedge is in lace the free ends 56 are spread transverse y as indicated in Fig. 4 to prevent the wedge from creeping or loosening by reason of the constant jarring action of the car and the vertical strains to which it is subjected on the carline. V

To support the usual running boards the clamps are provided with angular clips are riveted thereto, said cllps providy whic ing a vertical member 58 to which the'runnin board saddles 59 are bolted at 6'1.

on purlins andridge pole are utilized in the roof structure, they are secured by bolts 62. positioned in apertures in the top web of the carline and extending down through the channel portion of the carline, said bolts passing through the purlins and ridge pole and secured thereto by nuts 63 threaded against the loweriface of the purlins and ridge ole. Said bolts 62 hold the urlins and ri e pole tightly against the ower faces of t e lateral flanges 19 of the adequate support for the main body of t e roof sheets between the carlines. In order to clear the rivet heads 63' of the bolts 62 the web of the inverted channel portions of the sides of the tering emclear such from side plate to side plat and secured.

the invention there are=shown four wedge clamps secured throughout the length of the carline and such four clamps have been found in practice to be suflicient securing means to rigidly. secure the roof sheets immovably down on the carlines without danger of the roof sheets pulling away or tearing loose from the clamps, but of course if it is desired the number of such clamps used may be increased or diminished.

The roof may be applied by first securing the carlines in place, and then laying the sheets down on the carlines so that adjacent sides of the roof sheets embrace the carlines in lapped formation, and the clamps, having the bolt riveted thereto are applied by inserting the bolt through the registering apertures in the web of the car'- line and the webs of the lapped side portions of the roof sheets, then a tapered wedge is inserted in the slot in each of the clamp bolts and the clamps are thereby drawn down, and, after the wedges are fully in place, their free ends are spread. The eaves edges of said roof sheets may be secured to the side plates either before or after the clamps are positioned.

The end roof sheet sections are formed similarly to the intermediatesections except one edge terminates in a depending flange secured to the end fascia or other member at the end of the car.
