HENRY A. GIIRIST'Y, OF KENILWOR'IH, ILLINOIS;

- can-Boer.

To all whom it may concern: I

Begit known that I, HENRY A. Crrn srr, a citizen 'of the United States, residing at Kenilworth, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Roofs, of which the followin'g is a specification.

The leading purpose and object of this invention is the construction of a car roof composed of sheet-metal plates in such a 'manner that the distortion or twisting of the car-body, due to; the strains it receives in transit or due to the uneven'loading of the car, will not injure nor tear the roofcoveringin other words, the main purpose of the invention'is the provision of a carroof structure which can satisfactorily withstand all usages or service without danger of causing leakage, the structure'of the roof beingsuch that it will at all times be rainweatherand wind-proof. To reach this re sult I do not rigidly and fixedly attach the roof-plates to the car-roof frame, butassociate the parts together in such a manner that the completed roof is what may be termed flexible or yielding Tthat is, the parts of the roof structure can give sufliciently or yield to the various strains without danger of rupture' A roof embodying the structural features andcharacteristics of this invention is very easily repaired, due to the facility be removed and replaced, which, of course,-

-renders the assembling of the parts in the first instance economicaland free from difficulty or the employment of any great amount of labor.

In the accompanying" drawings I have illustrated a preferred and desirable embodiment of the invention in order that those skilled in this art may have a full and complete comprehension of what the invention covers. In the various views of these drawin'gs like reference characters refer to the same part throughout,

In the drawings-I igure 1 isa fragmentary perspective view of a portion of a carroof structure incorporating my invention;

Fig. 2 is a cross-section through the roof of the car; Fig. 3 is a longitudinalsection on the line 33 of Fig. 2; Fig. 4 is a fragmentary side elevation of the car-roof structure, certain of the parts being broken away Fig. '5 is a longitudinal section on the line I 5-5 of'Fig. 2; Fig. 6 is a perspective View of one of the carlines; Fig. 7 is a perspective car just inside of the with which the roof-plates'may' of its web 20 a support I extended flanges Patented Oct. 17, 191i.

View of the straps which attach the edges of the roof-plates to the sides of the car-body;

served that each carline 20 is of channel I shape, in cross-sect1on,

consisting of a web 21 having along its .oppositelongitudinal edges a pair of upstanding- stiffening flanges 22, 22, the whole carline being bent at the center to provide the proper inclination or slope to the two sides of the roof. At each end each carline has its flanges 22 cut away or omitted, the web being bent down at these points to provide attachment-plates or ears 23, 23. As is clearly indicated, these cal-lines are applied to the .tops of the car-' body side walls 24, with the ears or attachment sections 23 disposed outside of and against the outer face of the side walls. As I have indicated vin the various figures, one of these carlines is used at each end of the end wall 25, so that one of the upwardly-extended flanges 22 rests against the inner face of such.end

wall. At its apex each of these carlines has resting upon it and secured to the top face 26 composed of two channel sections 27 and 28, whose webs 29 and 30 areriveted together in contact, as shown in Fig. 10, the lower flanges 31 and 32 of the support being inclined to conform to the inclination of the two sides of the carline proper, while the upper oppositelyof the same two channel sections are disposed in a single horizontal plane. ploy a cap-strip 33 of inverted channel con struction-that is, its web rests directly upon and is secured to the top flanges of the various supp'orts26, while 1ts marginal flanges extend downwardly, as is clearly in- Fastened to these supports 26 I sin-- dicated in Fig. 1. On top of the cap-strip I i use cross-supports 34, to the tops of which are secured, in any approved manner, the

longitudinal running-boards 35, which, as

arranged side by side, are of considerabli greater width than thecap-strip beneat them. If preferred, these running-boards may be made in comparatively short secremoval and appllcations to facilitate the tion of the metal roof-plates, hereinafter described. Each 0t these sheet metnl root'- plates consists of it main body 36 (Fig. 8) having along its upper edge av marginal upwardly-extended flange 37, the plate having also at its lower edge a, downward-turned flange 38, the extreme edge of which bent up at 89 to provide at marginal portion of double thickness. Along each of its two sides the plate 36 has it downWard-turned flange 40, the lower end of which is bent in- Wardly et ll in contact with and riveted to the flange 38. These various roof-plates are applied to the roof, while the outer running-boards are removed, permitting the inclination of the roof-plates suiiicicntly to enable the operator to introduce the flange 37 beneath. the corresponding side flange of the longitudinal cup=pletes 33 the roof-plate being then swung downwurdlv 1 into operative relation with the cal-lines, with its flanges L0 residing in the troughs of the cerlines and disposed slightly away from the up-turned flanges of such cerline this construction permitting movement of the car-frame and roof-plates relatively to one another Without tearing or rupturing such plates. Above each half of the carline is employed 5}, board or similar member 42, Which rests upon the adjacent portions of two of the root-plates. Each of these boards is accommodated within one of the airline-caps 43, each of the letter at its lower end having av depending car 44, dapted to overlie the adjacent parts of the llenges 38 of two adjacent plates, and also to overlie the ea" 23 oi the czu'line in conne tion with which the cztpstrip is used. The upper end of the cap -23 mid the board 1 -12 which it houses are received beneath the Henge oi the longitudinal (rep-strip 33, the latter being notched at for this purpose.

Extended along the top portion of each side Wall of the car is n sectional strap com posed of a plurality of parts {l-(l, ouch of :moiul of the root-plate.

simightening which has one end l? oilset to receive the unbcnt end oi the next adjacent stmp sccl tion. These burs are'upertiu'ed at 43 in aiiinement with-the holes l9 and ot the cal-line mid cap-strip .urs, and through these registering holes 1 employ belt; 51, which extend through the side \\':ill of the our and. bold t getlicr the various puris oi the root ctmstiuction. ".lhe straps ll as will be n ticed, are positioned ju t above the scum. or reinforced portion Phi ol the v:i2'ious flanges 38 ol the cur-root plates.

At ouch end i the cuuboi, i use a very narrow 1o 7 plate which in other rcspccts is suoshmtiull lil o the broader and more subsluuiiui plaice lormiiu; the root covering".

it should be nppzirent from this description and illustration that ouch oi? the roofplutcs has 21 loose connection with the V71- rious cal-lines, and is loosely received beneath the (up-strip 233, so that as the cz1rbody yields or dcllects or becomes distorted, or the side walls bulge outnnrdly, these plates camgive or yield relatively to the roof lrnme Without their becoming torn or otherwise injured. Furtheri'noi'o any plate may be readily removed and replaced by merely removing one or more of the straps 46, un-

Owing to this construction, there is no wear or ciiltting of the cup-strips on the root-plates. in other words, there is no \stfi'll'lllg of metal on metal. Furthermore the supports 26 at the tops of the carlincs assist in preventing the curlincs from out thut is, assist in preventing the root from being displaced or dis tor-ted.
