' sa erronea i in 'which a rigid, durable and fireproof.

' sheathing is required.

The invention 1s one which is particularly adapted for car building for the reason that l A, l in appearance it is indistin ruisliable from the wooden sheathing ordinari y employed in the building of cars,.so that a train composed in part of wooden and in art of metallic cars covered with the sheat iing of the resent inventionwillpresent a thoroughly iarmo` nio'us a pearance.

Anot 1er feature ,of the invention is the ease with which the sheathing can be formed or stamped, and the facility with which it can be applied in place, which renders y,the building o cars much less -dillcult than where wooden'sheathing is applied in the ordinary manner. Another object of the invention is to provide suitablev openings adapted to receive a `iilling of deadening material which renders the structure impervious to heat and cold and deadens any sound which might otherwise accompany the employment of metallic cars on railroads.

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings Figure 1 is a perspective view of the sheathing of the present invention; Fig. 2 a cross sectional View showing the sheathing applied to a rail or beam; Fig. 3 a cross sectional view showing the method of employing a double sheathing; Fig. 4 a perspective view showing the method of marking the sheathing to represent tiles for use in bath rooms or similar structures; Fig. 5 a sheathing foi a curving surface; and Fig. 6 a slightly modifiedl form of dove-tail.

The sheathing in its simplest form consists essentially of a continuous plate 5 provided at uniform intervalswith parallel grooves or Bpeciilcation of Letter Patent. Application filed December y13. 196- Boi'ial No. 847.860.

channels 6 and intermediate rit fes 7. The cross walls 8 ofthe com )anion dliannels are formed from sections of t 1e same plate l 'ng in they same plane, so that a `llat attac 'ng surface is provided which adapts the sheath ing for attachment to a llat surface, but in cases iii which it is desirable to attach the .sheathing to a curved surface the cross walls may be given ,a suitable curvature as illustrated in Fig. 5. lhe cross walls 9 of the ridges `present likewise a uniform surface extending parallel to the portions of the plate forming the cross walls ofthe channels; but it will be understood that the shape of the sheathing as a whole may be curved or straight, depending upon the structure to which the sheathing is to be applied. 4The side walls 10 of the grooves or channels diverge toward the bottom, which the groove andj provides an opening contracted with respect to the bottom of the groove.

'As shown in Fig. straight and extend in an oblique angle to the cross walls or faces, but this formation is not essential, since the side walls may be curved, as shown in Fig. 6, provided only that the contracted opening formation be maintained.

In combination with the continuous channeled plate are employed a plurality of independent strips 11 each having an outer cross wall 12 in alinement with the flat`cros's walls lof the ridges, and having divergent side walls 13 adapted to register with the side walls of the dove-tail grooves or channels, which arrangement ermits the independent strips to be inserted into register with the Gives a dovetail formation to 2, the side walls are i grooves or channels in such a. manner as to similar in all respects to that hitherto described, are em loyed, the continuous sections being lai face to face, bringing the cross Walls of the channels of each section. into register with one another and thereafter `Securing the parts together by means of rivets or lsunilar securing means. Thisy y"arrangement affords a sheathing havingl a taclhedto an I-beam 1li or otherlsupporting at inner as well as a flat outer surface, and 4gives a doublethickn'ess to the sheathing as a whol which ishighltyl7 desirable in some` fs e -the adjacent grooves-'Iandfitheiafter the attaching bolts or rivets ar entirelyy concealed by the insertion'of the'jifn pendent sections so that the., appearancejlofg Vvthe" finished sheathing will -notfbe disfigured in any way by bolt or rivet heads"or"{other attaching means.A This methodl ofv attachment enables the sheathingl tobe .a plied withv great e'aseA and rapidity and facf'tates"they building of cars to a very marked de ee. .If desired,

thas aces withinthev sections of sheathing" `tinums b'cdy section havingfor'med therein a plurality of dove-tailed c may e lled with any suitable reproof non- Y' conductive lling 18 which serves to increase 'I the iireroof qualities of the sheathing to deaden t elsound and of heat or cold. Y

Where it is desirable to employ the sheathing for the, lining of bathrooms .or similar. tiled structures, the strips can be divided up by a series of cross marks 119arranged 'in staggered relation and intended to indicate tiling. By nishin fthe sheathing with a suitable' enamel a per ect imitation of glazed tile can 'be made.

From the foregoing description -it will be apparent that the sheathing of the` resent invention possesses the qualities o being to prevent'the ingress strong, neat'and durable and easy of manufacture and a plication. It possesses the further `rualities of being ireproof, noise proof, a proof against changes in temperafture. It can b e manufactured very cheaply,

' and the continuous formation of the sheathis attac ved to a ing enables it`to be attached to wide areas by the employment of a few` bolts orrivets which is 'a mucheasier method of attachment than lthat employed in attaching Wooden sheathing to cars, in which case itis necessary to attach each section separately tothe carst'ructure. .Y f Y A further advantage pertaining to the use of the sheathing of the present invention lies in the fact'tliat the corrugated nature of the sheathing permits lexpansion and contraction without any warping or buckling-ofthe ThisV is `very important in the' sheathing. buildin of steel cars in which the sheathing d steel frame, and if no provision Were ma e for expansion and 'con- :traction there would-be danger of warping or distortion of the sheathing. In the resent case the channels of the sheathing iiody are permitted to'open and close under the linfluence of atmosphericchanges to a suflicient extent to prevent any injury.
