Specification of Letters Patent.-

Application filed January 28, 1910. Serial No. 540,623.

To all 'whom' it may concern.: l

Be it known that l, JoirN MAiioLD, a citiresiding atMadison, in the county'of Madison and State of Illinois, have invented new and useful lm-l novements in Car-Roofs, of which the following is a specification. This invention relates to improvements in car roofs and has'for itsyobject the provision of a device dt that kind comprising a philrality of metalisheets so constructed that they will not be displaced or sprung by the vibration of the car tov which they are applied. y

Another object is the provision of a locking member for securing the sheets-'together whereby the usual method of employing bbards andpnails to secure the sheets to the .car will be dispensed with.

With these and other objectsin view as will more fully 'hereinaftef' appear, the present invention consists in certain novel details of construction, andarrangement of parts hereinafter to be'moreI fully described, illustrated in the accompanying drawings and more particularly pointed out in the apclaiins; it being understood that various changes in the form, roportion, size and minor 'details of the device may be made, within the scope of the appended claimstwithout departing from thespirit or sacrificing-any ot the ladvantagesof the present invention. Y 'l In the accompanying drawings forming a part of the specification:v Figure l is a plan view of a car roof showin proved device applied thereto. Fig. 2 is an end view of the u per` end portion of a car and showing the siieetsin end elevation. and the cap plate for covering the said sheets. Fig. 3 is a vertical sectional view approximately oii the'line 3-3 of Fig. 1. lFig. 4 is a detail perspective of one of the sheet-s.

Fig. 5 is a similar. view of the locking mein- The body of the car is designated by the numeral 5,.the sheath rooting by the numeral scription of the same will not be' given. i

sheets are arrangedl transverse the roof 5 and extend from points adjacent to the ridge 8, to the eaves 7. rIhe sheets may be of any desired'width and arepreferably of sheet' iron or analogous material. By reference to the dravitiiigs itwill be 'seen that each plate has itsiirnarginal sides" bent over one face of the sheet'l as shown at A10 and 1]..y

These bent portions yconstitute locking tongues to engage with a locking member to be-presentlydescribed.' The outer ends of the plates are bent downwardlyl and are secured to the eaves 7 by nails or the like, while the inner ends of the lates are bent upwardly and at right anges and extendv to points adj aceiit to the ridge 8.

What will subsequently bejtermed a locking member is designated in general by the numeral 12. This member` is formed of 4a single 4piece of sheet metal corresponding approximately in length to the length oi the sheets but considerably' less lin width than the width of said sheets. T he inner end portion of the locking member 1Q is reduced in width and bent upwardly as shown at 13` whereby atongue is formed, and portions with tlie'inarginal bent portions of two a jacent sheets. and when so positionedwillto firmly clamp said vsheets together.

operate The outer end portions of the locking' mem bers are bent downwardly and securedto the eaves 7 similar to the sheets 9. lt-willA be evident that when the locking member @nglgis inner end portions of two ladjacent sheets and when so bearing `will be secured by means of an auxiliary locking` nieinber 16.

a, with two adjacent sheets that the will bear' on the upwardly bent- 'lhe locking nieniber 16 lis of alength vcorrespending to the width of the upwardly bent inner end of each sheet and has its marginal sides bent ovei one face and spaced suii ciently far from the said face to receive the tongue 13 whereby the latter will be clamped to the said upwardly bent inner ends of the sheets.

It will be evident when the sheets are i secured by the locking members that the major portion of each sheet will not be rigidly secured to the roof sheathingthus permitting more or less movement-of the'entire number of sheets when the car 1s rounding curves whereby the usual warp of the car` top will be prevented.

In order 4to provide a covering for the adjacent ends of the sheets I provide a cap plate designated in general b the"numeral 17. This member is prefere Iy formed of sheet metal and Iis designed to house the ridge 8. Portions adjacent to the' opposite longitudinal sides of the cap plate are bent downwardly and atright angles as shown at 19 and 20, these downwardly bent por- T4 tions bearing on 1the sheets and locking members at points outwardlyr from j the locking tongues 13.' The opposite end'A portions of the cap plate are bent-downwardly and secured to the opposite ends ofthe ridgeS. With this construction itwill 'be manifest that the adjacent ends of. the sheets will be covered and it will be further observed owing tothe construction. of the marginal j. sides of the locking niembers and sheets,

that a tight joint will" be produced. which will prevent the entranceof water.

From the foregoing it" can be seen that I have vprovided a device which is simple iii structure 'and inexpensive tov manufacture which may be applied to box cars, coaches' oi in fact all rolling stock for railroads in which the Objectis provided with a roof.

Having thus described the invention, what 'is claimed is- 1. A car roof comprising a plurality of sheets having their outer ends secured to the eaves and their inner ends upturned and arranged adjacent to the ridge, each of said sheets having similarly rebent'side margins,V

and a locking strip having dside margins bent over one of its faces to receive the bent ,portions of the sheets, and a cap Aplate secured to the` ridge and extending'thr'oughout the length ofthe roof and having downwardly bent side portions to bear onv the said locking strips at points adjacent to the upturned inner ends of the sheets.

2. A- car roof comprising a sheets having their outer ends secured to the eaves and their inner ends upturned and arranged vadjacent tothe ridge, each of said sheets having similarly7 rebentside margins,

plurality of and a locking strip having side margins bentover one of its faces to receive the bentvporf tions of the sheets and terminating at its inner end'in an upwardly extending tongue to bear on the upturned inner ends of two adjacent sheets2 an. auxiliary locking member having similarly rebent side margins to receive the said locking tongue and therebent sides of the upturned inner ends of two adjacent sheets, and a ca plate secured to the ridge and extending tiroughout the
