UNITED STATES PATENT OFFICE.

GEORGE A. WOODMAN, OF CHICAGO, ILLINOIS.

RAILWAY-CAR END.

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Car Ends,

of which the following is a specification.

The primary object of this invention is to provide an improved metal end for railway cars of strong and substantial construction to withstand the shocks and strains to which the ends are constantly subjected in car service and also to strengthen the corner posts to which the end is fastened.

A further object of the invention is to provide an improved construction which will permit a material reduction in the weight of the metal car end without afi'ectin its strength.

ince my invention is particularly useful on Wooden box cars I have elected to illustrate this embodiment thereof but it may also be used on metal box cars and on wood and metal cars of other types for which it may be adapted.

In the accompanying drawings Figure 1 is a perspective vlew of an en of a wooden box car showing my improved metal end thereon;

Fig. 2 is a vertical centralsectional view of the structure illustrated in Fig. 1;

Fig. 3 is an enlarged elevation of one corner of the end as applied to the car;

Fig. 4 is a sectional view on the line 44 of Fig. 3. 1

The metal end, designated generally by the reference numeral 5, is made of sheet metal, preferably in three sections which are arranged'one above the other andextend entirely across the end of the car. The lower edge of each of the upper and middle sections laps over and on the outside of the upper edge of each of the lower and middle Sections as at 6, 6, (Fig. 2) to shed water and snow, and these overlapping edges are securely riveted together to form the com plete metal end in one piece. The side edges 7 of the sheet metal end are bent around the corner posts 7 and are fastened thereto preferably by bolts extending through the corner post alternately from front to rear and from side to side (Fig. 4). The upper edge portion of the sheet metal end is bolted to the end plate 8 beneath the end fascia board 9 and the lower edge portion of the sheet metal end is bolted or otherwise secured to Specification of Letters Patent.

corresponding to the end depessions 13.

The vertical depressions 14 are preferably located at each end of the buffer block channel,'and rolled steel sections 15 are secured to the sheet metal end adjacent these two' depressions, as .shown in Fig. 1. These depressions produce, in effect, a corrugated end having transverse corrugations ending in vertical corrugations and intersected by intermediate corrugations. The depressions 12 in one face of the sheet metal end form corresponding projections in the other face thereof and these depressions and projections are located at one side of the plane of the sheet metal end and preferably on the inside of the end, although the position may be reversed if desired.

My invention provides a sheet metal end of strong and substantial construction which will withstand the shocks and strains to which car ends are subjected and which, by reason of the reinforcement aiforded by the corrugations, may be made of a comparatively thin section of metal. The novel disposition and arrangement of the corruga tions provides a maximum integral rein forcement of the sheet metal end which can be produced without breaking or unduly The vertical end corrugations 13 not only reinforce and strengthen the ends but also the corner. posts which is highly important and, so far as I know, has never been done before.

I claim: 1. A sheet metal end for railway cars having plane sections at each end bent.

2. A sheet metal end for railway cars having a plurality of transverse corrugations, parallel vertical corrugations spaced apart and intersecting the transverse corrugations between their ends, and rolled sections secured to the end adjacent said vertical corrugations.

3. A sheet metal end for railway cars having a plurality of transverse corrugations, parallel vertical corrugations spaced apart and intersecting the transverse corrugations between their ends, androlled Z-sections arranged on the end with their inner flanges located adjacent inner edges of said vertical corrugations and fastened to the end and with their outer edges projecting outwardly over said corrugations.

4:. A sheet metal end for railway cars having a plurality of transverse corrugations, a pair of vertically disposed rolled sections spaced apart and from the side edges of the end and secured to the end across said corrugations, and a buffer block section secured to the end between the sections and also secured at its ends to said rolled sections.

5. A sheet metal end for railway cars having vertical corrugations adjacent the side edges thereof, a plurality of transverse cor-- l rugations terminating at their ends in said vertical corrugations, a plurality of inne: vertical corrugations spaced from each other and from the side vertical corrugations and intersecting said transverse corrugations, rolled sections secured to the end at the inner edges of said inner vertical corrugations, and a buffer block section secured to the enjd between the rolled sections and also secure at its ends to said rolled sections. v

6. A sheet metal end for railway cars, a plane section at each side adapted to be secured to a corner post of the car, a single vertical corrugation adjacent each of said plane sections, a single vertical corrugation adjacent each end of the car buffer block, each of said vertical corrugations extendingfrom a point adjacent the car end sillto the point adjacent the car end plate, and a plurality of horizontal corrugations extending between adjacent vertical corrugations.
