WILLIAM ERASTUS WILLIAMS, OF CHICAGO. ILLINOIS.

STEEL END FOR CARS.

Specification of Letters Patent.

Patented Feb. 23, 1915.

. ,l i Application filed February i9, 1914. Serial No. 819.683.

To all whom it may concern: Y

lBe it known that I, WiLLLiM EiiAs'rUs WILLIAMS, a citizen of the United States, residing at Chicago, in the'coiinty of Cook and State of Illinois, have invented a new anduseful Improvement in Steel'En'ds for Cars, of which the following a specification.

Railway cars receive severe shocksand impacts, by the sudden stopping of the cars andin coupling them in switchingand this 4shock oftenfshifts the loadsA on the inside of the carsland drives them backward into the ends'and often times punctures, breaks and destroys rthe ends of the cars.

' Thefobject of my invention is to produce a light, strong and cheap end that will withstandthe shocks of this serviceand at the sametime be most servieeableas a car for normalcar services. j A

References will be had to the accompanying drawings, in which: s" 1 Figure 1 is an end View of abo'x car emV bodying my end.. Fig. 2 is an endls'e'ctional elevation of my end with a small'portion of it showing from the outside the connection of the end to the corner post. Fig. 3' `is va horizontal section showing corne'rpoi'tion of a car in which the corner post and sheathing are of wood. Fig. 4 is a View lsimilar to showing my end `used without the flanges turned to embrace the outside of the' corner post, land it also shows in plan the bottom flange of my' end. Figs. 5, and 7 show'the arrangements of my end when thel same is rused in connection with ay i.steel angle corner post and inside wood sheathed car, Fig. 5 being analogous to Figs. 3, 4. Figs. 5 and -9 are enlarged details-of the ribs-ofmy end. Figs. 10 and 11 are enlarged sectional views corresponding to Indrawing, 2 `,indicates the steell sheet ot my end; In this heet I vforniribs 3 by puttn'gvv sharpV folds `in the Vsheets which are lbent up and foi'mithe ribs, 'and I extend these' ribs across the end of the car lat intervals of sufficient distance apartA to give the required stiffness to the sheet.

In 'the construction shown in Fig. 3, I bend the end of the sheet cross-wise of the flanges around into the angle shown by 4, Fig.' 3. 5, indicates thel rib 3 at the curve o'f the bend around the corner. Bolts 6 and 7 pass through the sheet and the corner post 'and securely fasten the end to the corner post. p

In Fig. i the steel end sheets do noty inn p around the corner post forming the flange 4, but terminate at S and the boltsfG fasten;

the end sheets to the corner post.

The present practice in car construction is turning toward a steel frame for the box l car, having a wooden sheathing on the inside and when such a. cai' is used with my steel endgthe corner post will appearl as I prefer to make. them iii accordance with Figs. 5, 6 and 7, wherein 9 indicates a steel angle foi' the corner post; slots 10 are cut through one flange of the angle at locationsl registering with the position of the rilis3, of, the end sheets and these ribs 4project through the slots 10, as is shown by the iig! his does not weaken the corner post' f for the reason that lthe steel end sheetsthem?'` Il F8.

selves', are bolted 'securely by the -bolts 6 through the flanges of the angle and makeL up for any loss occasioned by the slots In making my steel end Iprefer l,to make it out of inetal t or of an inch thick and the ribs 3 so stiften it that the results' obtained will he even greater using of an inch sheet for thesteel end la@A than would." f

be the case witlr of an inch sheet as sonic ltimes heretofore used. Y

On the inside of vmy steelend I prefer to f' line it with wood, and this wood may befany' thickness desirable from gv of an inch up'tof I wood slieathingis 3,- of an inch, as a thick not necessary since my metal sheets provvide almost a complete smooth plate siii'face'foijv the wooden sheathing to lie in contact with, and thus almost no breaking vstrain can "go on the sheathing as thc metal will bear all of the strain that may be occasioned by the impact oi any load on the insidefot` the car. In order to sheathing on the inside of my Asteel end I make trie ribs 11, 12 and 13, leaving a cavityr` not-trickle down on the inside of the sheet but will drop ofi' on the outside.

The lower margin of the sheet 2 is bent inward forming a flange 19 which rests upon and is bolted to the sill 18.

facilitate the fastening of this and any loose material with'which the car.

may be loaded, and then on the nextvloading of thel car this material may be shaken out by the vibration of the carv and injure the new `load. With my steel end and wooden sheathing, no voids areproduced that will remain open or need to be filled, and hence this feature is a great desideratum. Further "with a steel end made of corrugated material and sheathed'with wood which rests against the summits of the corrugations as is Avordinarily the case as heretofore used,

this wooden sheathing is likely to be puncjtured between the corrugations by shifting loads that Will go in contact with the sheathing in small spots like the corners and ends of bars of iijoiror small ends of sticks of timberl and this Wooden sheathing with that class of steel end is objectionable, but with my end these objections are overcome.

Forcertain kinds of loading in a car, it is desirable that the steel ends should be sheathed and no other form for steel ends heretofore used will permit the steel to be used in connection with a wooden sheathing that will not cost more money for` the same service than with my steel end. This feature is a great point in favor of my invention. Y

It is desirable to have a wooden lining to a car from the stand oint of insulation in temperature and it aids often times in securing the load in the car in a fixed position by nailing cleats or braces to the insidevof the car. y

My endgives all the advantages obtained by any wooden end-and all advantages ob` tained by any steel end and yet it can be so cheaply made that it is a competitor in cost lfor any form of end construction of a car. One-of the features' which permit my end to be made cheaply is the fact that in mak-l ing ribs 3, the metal may be bent when it cold and cold operations are cheaper than hot operations.

Heretofore all other steel erations.

.i ends yet used have beenformed by hot op What I claim'is: y 1. In a car end, the combination with a metal vparallel lines to ,form an internally plane member having a series of tightly closed external rib's' and a series ofintermediate in-l ternally open ribs, each of uniform -width structure having spaced horizontal ribs of a thickness double that of the sheet, of wood sheathing transverse with respect to the ribs and secured to the plane face of the sheet.

2. In a car end, the combination with a uniformly thin metal sheet folded at intervals along parallel lines to forman/internally plane member havingfa dseries of external, tightly closed ribs and ate internally open' ribs, of woldistrips fixed in the internally open ribs". sheathing fixed to the strips, andv nie ,A Aor r securing the structure to the boidy of'facarJM- 3. In a car end, the combination, with am metal sheet folding along parallel lines top-gv form a series of external horizontal ribs, of A'80 a second sheet above the irstfsimilarly folded and having its marginal rib overla'pping externally and interlocking with the marginal rib of the first sheet, means for-, binding together the overlapping lvportionsa of the two sheets, and means for securing Athe sheets ,to the body ofthe car. A

4. Y steel end for a car formed ofjara't sheet havingribs formed in the body thereof in a manner that leaves a substantially flat surface on one side of the sheet, said ribs extending cross-.wise of the end'of the car, with a corner post made of metal and metal sheet folded along parallel lines ,to

form a series of external parallel ribs of a thickness double that of the sheet and an upper marginal internally open rib, of -a second sheet similarly folded and having a lower marginal open rib overlapping and interlocking the open rib ofthe first sheet,a Wood strip fitti y the open rib of'the lower sheet, bolts pass ng through said strip and the overlapping` portions of? the two sheets,- and sheathing transverse with respect to the strips and secured thereto.

6. A car end of sheet metal folded along from. side to'lside of the sheet, combined S with wood strips secured in the open ribs, and Wood sheathing transverse with respect ,to the lstrips, securedthereto,v and covering.' the plane non-ribbed face ofthe sheet.
