A oAanooF.
Application filed vMay 9,
To all whom t 77mg/ concern.'
Be it known that I, IVILLIAM D. THoMrson, a citizen ofv the' Unitedl 'States of. America, residing atf`Detroit, inthe County of'lVayne and Statey of Michigan, have'invented certain new and useful Improvements in Car Roofs, of which the following is a specification, reference being hadthereinto the accompanying drawings. l
The invention relates to ear. roofs of the typeknown ais-outside roofs, and consists in the' novel construction of the weatherproofing sheets andr means. for securing the same as hereinafterset/v forth.
In the drawings:
Figure lis a cross-section through the roof;
Figure 2 is a plan view thereof;
Figure 3 is a section longitudinally ofthe roof Vand show-ing the mullion and. weatherproofing cap in cross-section; i
Figure is a similar view of the modified construction.
In the Construction of outside car roofs it is usual to; provide metallic weatherproofing sheets which over-lie the board load-sustaining roof andwhieh arefsofse-y cured as to permit relativeInovement to compensate for Ithe weaving of th'ecar frame. Then the Car is subjected to shocks, such as occur in shunting or by the sudden application of the brakes, there is a tendency for all of the sheets to shift longitudinally and this frequently results in tearing at the points where the sheets are secured. For instance, if the sheets are secured at the eaves, but not at the.ridge, there will be a twisting stress tending to tear the securing flange. The same is true if the sheets are secured at the ridge and are free at the eaves. Again, if the sheets are provided with a limited freedom in all directions, they will slide back and forth under different shocks and will be injured thereby.
It is the primary object of my invention to hold the sheets from shifting in relation to the car frame under longitudinalshocks, while at the same time permitting a relative movement to compensate for weaving. It is a further object to obtain this result with an exceedingly simple construction and one applicable to roof structures which have heretofore been used.
In detail, A. is the load-sustaining board 1921. Serial No. 4G?,83.`
roof supportedupon the ridge pole B and piate'C. I) and D', etc. are weather-proofing sheets provided with upstanding and return-bent side flanges E, said sheets being arranged between mullions or stop strips F `on the loadLsustaining roof. The weather-proofing is completed by caps G which embrace the mullions and are pro vided with return-bent fianges H for engaging the fianges E, the bends being sufficiently ing sheets from shifting longitudinally and tofthis end I have'provid'ed clips J',prefer ably formed of sheet metal,` whichilare se-r cured to the bolts and extend transiersely sheet is secured by the flangethereof which l Y is adjacent to the next mullion. Thus each sheet is secured to a mullion so as to preclude any shifting longitudinally of the Car. The clips J preferably engage recesses Ii formed transversely of the mullions and the outer ends of the clips are downturned at Il and secured to the fiange Eby rivets M.
In the modified construction shown in Figure 4L the clip J is arranged beneath the mullion instead of above the same and is provided with an upturned flange for engaging with the flange E. lVith both constructions there is nothing to prevent relative movement of the caps G and the sheets o|r relative movement of the sheets in relation to each other, but each sheet is held from movement longitudinally of the Car and is retained in a position of parallelism to the mullion.
The roof is completed by any suitable rigid weather-proofing cap, such as N, and eaves weather-proofing means such as the return-bent flange O engaging a cooperating return-bent flange P on a flashing strip Q. These features are not, however, a part of the present invention.
What I claim as my invention is: 4
l. In an outside car roof, the combination with a load-sustaining roof, of 'a series of metallic roofing sheets overlying said roof, weather-proofing means between the sheets permitting relative movement thereof, and means for holding each sheet at one only of the side edges thereof from shifting longitudinally of the car.
2. In an outside car roof, the combination with a load-sustaining roof, of mullions secured thereto, roofing sheets between said mullions having upturned flanges, caps embracing said mullions and having a weatherproofing engagement with the flanges of adjacent sheets, and means for securing each sheet at one of the side edges thereof to said mullion to retain the same from shifting longitudinally of the car.
3= In an outside car roof, the combination with a load-sustaining roof, of mullions thereon, bolts for rigidly securing said mullions to said roof, weather-proofing sheets between mullions having upstanding flanges adjacent thereto, weather-proofing caps embracing said mullions andhaving a weatherproof engagement with said flanges, and clips for securing one of the flanges of each sheet to said bolts to prevent shifting of said sheet relative to said mullion longitudinally of the car.
4. In an outside car roof, the combination with a load-sustaining roof, of mullions on said roof extending from ridge to eaves, bolts for securingsaid mullions to said roof arranged respectively adjacent to the eaves and ridge, weather-proofing sheets between mullions having upstanding return-bent flanges, caps embracing said mullions with downwardly-extending return-bent flanges embracing the flanges of the sheet and permitting relative movement, and clips secured to said bolts engaging transverse recesses in said mullions and having down-turned por tions secured to the flange of one of said sheets.
5. In a car roof, the combination with a load-sustaining support, of roofing sheets upon said support, weather-proofing means between the sheets permitting relative movement thereof, and means separate from said weather-proofing means for holding each sheet from shifting longitudinally of the car roof.
6. In a car roof, the combination with a load-sustaining support, of members extending transversely thereof, roofing sheets between said members having upstanding flanges adjacent thereto, weatherproofing caps embracing said members and having a weather-proofing engagement with the flanges of adjacentvsheets permitting relative movement thereof, and means connecting one of said members with an adjacent sheet to prevent shifting of said sheet relative to said member longitudinally of the car roof.
7. In an outside car roof, the combination with a load-sustaining roof, or roofing sheets `upon said roof, weatherproofing means between the sheets permitting relative movement thereof,and means engaging each sheet at spaced points at one of the side edges thereof for holding said sheet from shifting longitudinally of the car.
In testimony whereof I aiX my signature.
WILLIAM D. THOMPSON.
