To all/whom it muy concern:

le it known. that We, WALTER P. MURPHY sind 'Vm'ron SissoN, citizens of the United States, residing et Chicago, in the county of Cook and vStute 'of Illinois, have.

inventedcertaiii new and Iuseful Improvements in Ra1lWay-CnrEnd Constructions,

.of Awhich thefollowing is a. specification.

Uur'invcntion relates to railway carend constructions, and vthe invention has for its .object tvo-provide an all metal car end constructionnof vnovel character whichwill bev unusually strong und durable throughout, which may, be convenient-ly and economically manufactured, und which shall possess certain other desirable `sind advantageous features to be hereinafter v, described and claimed.

It has been proposed to construct e cui' end of u single sheet of inetul dished out- Wardly and foi-mcd with concentricelly srranged circuler corrugations, the lutter tor the purpose of giving strength und rigidity to the plate. This construction, however, is very ditlicult and costly to manufacture owing to the size of the shectand the configuration which must he given to it by the pressing or stamping operation. Moreover, u car end. formed from :i single sheet neces throughout us thick tion of the end of the cur luis to be which must stand the greatest strains, that is to say, t-lic lower part. This means that an unnecessary umountof metal is used end the end is made unnecessarily heuvy. Furthermore, when the end of the cnr is substantially rectangular, in the case ot :in ordinary box cui', the cular cori'ugutioiis leaves the corners of the plate Without i'eiiiforceiueiit.' Thcnecessity for strength is just of the plate, and particularly the .lower corners, ut thc middle. Uur invention provides nu ull inctzil end construction which, by obviutiiig these objectionable features.

. gives increased strength und duruhility und iV-t lthe same time reduces manufacturing cost.

Referring first. to the forni of end construction shown in Figs. l to 5 inclusive, 25 designates one ofthe end sills of u railway hoi; cur, 25, 26, the flooring of the cur, und 28 'the root shown :is supported on the ridge poleland purliiis 30. The csr construction shown is n familiar and usuel type which, of course, might he modified, it' occasion demanded, Without departure trom our invention; the

naines given to the various constructionnl elements beingused with that understanding. 3l designutes u metal plete foi-niet witlivlzinges 32 .which overlap the corner posts 26 and are bolted thereto. by the bolts 33, 'the outer comers of tlieposts being cut sway so that vthe ienges 'and their 'bOltS in practice, making', the 'sheet und heavy es that porprovision of the pluie with cir" corncr posts, 27 the' :is greet ut the corners Aso ' of the contents of the car.

.- 5l come within the sheathing 33 of the car. This protects the attachment of the plate to the post. The lower edge of the plate 31 is bolted to the end siilr25A by the bolts 34. 35 is an upper plate which lis preferably considerably thinner andlighter'than the plate 3l and w'hichis formed with the tlanges 36 which overlap and' are bolted `to the corner posts 26 as in the ease ofthe flanges 552 on the lower plate. Plates 31 and 33 are preferably formed at their meeting edges with the outwardl 'projecting flanges 37, 38 which are secure together by the rivets 39. The flange 88 on plate 35 is preferably wider than flange 37 on the lower plate and is preferably formed with the depending lip 38a. By this arrangenientwater cannot enter thev car. along this joint between the plates. ln Fig. 6 the flange 38" projects beyondy the flange 37b on the lower plate lint has no lip. ln Fig. 7 the flanges 37, 38C are bent downwardly. The platesare formed with eorrugations 40 which arc preferably horizontal and extend ,1 substantially to the margins of the plates overlapping the corner posts. "While the corrugalions are necessarily tapered down at ltheir extremities, except at these extreme points they are preferably of substantially the saine depth throughoutthe plates in this manner the entire portion ofthe plates inside the framework ofthe car is uniformly reinforced. No part is appreciably weakeror stronger tlian'any other part. This "1s important because the end of a car is not in the situation of a beam having the heaviest load at the point midway between its supports. The sidey portions of a car end are as likely to be subjected to heavy strains as the center portion, all depending upon the character However, the heavier articles, such, for example, as rails, pipe and the like, are sure to be placed in the lower' part of the car. If the car isloaded up to the roof the upper part of the load is made up of lighterarticles. It is therefore possible if the end is made in two or more sections (obviously, lif desired, it might be made up of more than two plates) to econoinize in metal and-save in dead weight, by forming the upper plate of lighter material than the lower one. Preferably the upper plate 35 is formed with an inwardly projecting flange 41 which carries the end of the roof structure of the car doing away with the necessity of the usual end plate. f `'In the construction shown in Figs. 1 to 5 inclusive, the ridge pole 29 and purlins 31 are supportedvby the flange 41, the ridge pole being shown as secured to the flange by means of an angle clip 42 attached to the flange 4l by rivet' 43 and to the ridge pole by bolts 44. If desired the flange 41 By forming Loenen may be omitted and the usual-'end plate employed as will be hereinafter .l described. Flg. S illustrates a modification in the form 'ofthe lower plate. Here the lower plate lvdesignated 45 is formed with an inturned flange 46 at its lower edge. which-is secured by vertical bolts 47 to the end sill'25.

Figs 9 to 14 illustrate afsomewhat die'rent embodiment of our invention.` lnthis construction the plates 48 and 49 arebowed or curved outwardly (this Yconvenity.being substantially uniform from .top to bott-oni) instead of being flat as in the form ofthe invention previously described. 'lhese {igures also illustrate a different arrangement of the strengthening corrugations; which arrangement though shown ifi l'connection with the curved plates might be. used .'witl'i plates which are flat. y The formationof Y corrugations of considerable depth and extending quite close to the edge of afmetal plate is an operation which, while feasible, is likely to be somewhat difficult owing to the tendency of the metal to drawv and dis:

tort the plate. To overcome this difficulty'v the plates shown in Figs. 9v to '14 inclusiveare formed Awith a series'ofcentrally arranged'corrugations 50, preferably widest at their middle points and tapering down toward the ends, which preferably do not extend very close to the'edges'of the plate. Between these corrugations at each lside of the plate is a series of similarly tapered corriigations 51 which project outwardly beyond the extremities of the corruga'tions 50. By this arrangement the stamping of the corrugations is facilitated, because the main set of corrugations 50 do not have to be cariied out uite so close to the edges of the plates', w iile the portions of the plates within the framework n"of the car end are given a reinforcement which is substantially uniform throughout. The lates 48 and 49 are shown as formed with gauges 52 which overlap the corner posts and the upper plate 49 is formed with an inwardly projecting flange 53 which :supports the roof structure in the manner described in connection with the construction shown in Figs.. 1 to 5 inclusive. In Fig. 13 we have shown a construction utilizin the ordinary 'and plate which is here esignated 54. The upper sheet metal element 55 of the end. structure is secured to? the wooden end plate A; construction'whih is modified with ref spe'et to the curvature of the end lstillua ltrated in Figs. 16,to 19 inclusive.` Anforderof' the Interstate. Commerce Commission. having-for its purpose to insure a "sufficient end ladder clearance provides thatnopart of the car above the end'sills. within 86 inches from the side of the ca'rsvhall extend' `to within twelve inches of a vvertical plane parallel witnthe end of the ear and passing nooners through the inside face of the coupler knuckle. lf the end o the cor is convex` on u segment oi? e cylinder, the inner corner ot the end ladder may, depending on the radius of' the curve, project out for e considerable distance beyond the farthest projecting point. of the cnr end Within the thirty inches. This Ineens a shortenin of the csr body in order to comply with alle order or" the interstate Commerce Commission. lt muy be desirable for obvious reasons to malte the plates convex and this conveuity may be obtained Without unnecessarily shortening the car by forming the plates on a reverse curve that is to say so es to provide depressions at the sides of the plates on each side of the central bulging` or protruding portion f the end structure. 57, (Figs. i6 to '19 inclusive) designate plates .so formed. 59 designates the ldder. lt will be seen that the inner corner of the ladder with this configuration of plate pro jects very little farther' than the outer corner.

life have shown and Adescribed the invention as applied to u box car o1c usuel construction. lt will be understood that the Kterm 4 box car is used in a broad signification to include, for example, Caboose cars or other house cars. The inventionis applicable to car constructions other than the par* ticulnr construction shown.
