EDGAR WEBSTER SUMMERS, OF PITTSBURG, PENNSYLVANIA.

HOPPER-CAR.

Patented April 18, 1909.

Serial No. 457,678.

To'all whom "it may concern:

Be it known that I, EDGAR W nnsrnn SUM- MERS, a resident of Plttsburg, 1n the county of Allegheny and Stateof Pennsylvania, have invented a new and useful Improvement in similar materials.

ing of the ore and insure discharge of the load,

and closed by a pair oflongitudinally ar- "ranged doors.

- The present invention is an improvement I on the car described in said application, and

the bod has for its objects to improve the sloping end doorrportions so as to prevent the lading from choking and bridging when it slides down to the discharge opening; to improve bolster construction in order to effective y take care of the stresses and also to permit readyaccess tothe space between said bolsters and the sloping end floors; to provide a horizontal web girder secured to the "draft sills for transmitting buffing and tugging stresses to the car sides, and-used in conjunction with an elevated platform so a r'- ranged as to prevent lodgment of ore on said web girder; and other improvements which will be hereinafter described and claimed.

In the, accompanying drawings, Figure 1 is a plan: view ofa portion of the carwith parts broken away and the'discharge doors omitted; Fig. 2 is a central vertical longitudinal section through the same; Fig. 3 is an end view of the carj Fig. 4 is a transverse section, the left hand portion being taken outside of the bolster and the right hand portion being taken centrally through the hopper; Fig. 5 is a vertical transverse section on the line 55, Fig. 2 and 6 is a deform of top'chord for the car sides.

tailedtransverse section through a modif ed The caris of the hopper type, having plate girder side walls extending for the full length of the bod and having firmly secured to their ends the Web plate 2 of the bodybolster. These sidewalls are provided atltheir upper edges with asuitable cord 8 and their lower side portions are formed by a separate plate 4 which projects down to the underlrame level and is then turned inwardly, as at 5, to support the lower edges of the inclined side hopper sheets 6. Dischargeopenin 7 occupies the s ace transversely of the carbetween the opper sheet 6 and is somewhat wider than the track, as shown in Fig. 1', and extends longitudinally of the car for a distance greater than that between the-inner truck wheels. This discharge opening is closed by a pair of longitudinally arranged doors 8 hinged at the sides of the car 9, and closing toward the center of the car, being closed by means of winding chains 10 passing over guide sheaves 11 and onto drums on winding shalt 1-2 mounted transversely of the car. The draft sills 13 extend inwardly beyond the'body bolster and at their inner ends are connected by gusset plates 14 to the end 310 ing floor plates 15.

" be car so far described, excepzfor the shape of the end sloping floor lates, is sub-- stantially the same as that o my application above identified.

The sloping floor plates have their side portions,'as at 16, sloping upwardly, viewed transversely of the car, and secured to the side walls by means of rivets 17. The portions 16 are on substantially the same angle as the sloping side hopper plates 6, and extend. inwardly to a line coincident with the side edges of the discharge 0 ening; that is,

side port-ions 16 of the lloor p ates are of substantially the same width as the sloping side hopper plates 6. These side portions 16 act as confining walls for the lading, and the space between the same is of substantially the same cross section from the outeru pper end of the end floor lates to the discharge opening, so that as tholading slides down the end floor platesto the discharge opening it does not need to change its cross sectional area, as is the case where the sloping end floor and sloping side hopper plates meet on a bias or diagonal line, as is the common practice. Consequently, the liability of the lading choking and bridging as it reaches the dischz-uge opening is practically overcome, and the free discharge of the load is assured.

A horizontal web girder 20, consisting of one or more plates, is secured to the lower edges. of the end floor plates, as at '21, and at this point is also laced atransverse reinforcing plate 22. T 1e horizontal web girder is secured at its side edges to the plate girder loo side walls of the body, and serves to transwit the bufling and'tugging stresses to said side walls. The outer end of said web girder is tapered, as shown in Fig. 1, and has flanged edges at 23.

A t the end of the overhanging portion of I the body is the end plate 24, and an elevated platform 25 is also provided in order to permit the train men to traverse a loaded train.

Ladders. 26 lead downwardlyfron each side of the elevated platform. ihe portion of the horizontal web girder which projects beyond the overhanging end of the body'is of less width transversely than the elevated platform 25,"as is apparent from big. 1, so that any ore which is spilled from the shovels in loading the car, can find nolodgment at the: end of the car except on the elevated latform. The s aces 27 underneath the la ders and inclos'ed y the end sill 28 and end side sill member 29, are open, and the run s of the ladder are small so that the ore will'not lodge on the same so that it is necessary to clean off only the elevated end platforms. Thismaterially reduces the amount of labor at the mines in cleaning the car before taking ithe same out of the pit. This is of advantage,

as the grade of ore in different arts of the same nnne varies, and as the olending .gor mixing of the *re 1s started at the mines, the

H operators are careful not to get even small quantities of orefro n one part of the mine into another, and go to considerable trouble 4 and expense to clean the cars of all ore lodged upon the same;

This labor is greatly reduced'by thecar described.

,The body bolster compiises side filling or- Web members 30, one on each side of the draft sill, and a bottom connecting plate or chord 31, together with the web plate 2 rising from the lower port-ion of thebolster and provided at its upper end with flange riveted to the sloping end ,floor plate The web plate 2 extends continuously from side to side of the car, and since the space cc-- through thedplate. This plate is stifl'ened or strengthene by means of bars, shown as angle bars 35, riveted thereto. These stiffening bars pro ect down inside of the draft SlllS and are riveted thereto, as shown In lr'ig.

'4, and are supported practically on the center bearin pate 36. They project upwardly and diverge outwardly dlagonally in order to effectively take care of the stresses which come on diagonal lines. This outward divergenceof the stifiening bars also pro the side walls, thus enabling the side Walls to laced onton the lines of the maximum be wi ith of the car, so as to increase the cubical capacity ofthe car.

The car illustrated contains numerous other parts, [but as they form no part of the invention, it is not deemed'necessary to describe the same.
