To alt Iwhen?, it Imay concern: K

13e. it known that I, GUSTAV A. RAnowsKY, oif Duluth, St. Louis county, Minnesota, have invented certain new and useful Improvements in DumpCars, ot which the following is a speciiication. r

My invention relates to that type of dump car, designed particularly for handling ore, receiving it at the mines and delivering it to the pockets at the dock.

'lhc object of my invention is to simplify and improve the apparatus shown and described in 'Letters Patent of the United Sintes, No. 899,682, issued to me September as, isos.

A further object is to provide a car, in which the load in the buckets will be ltransmitted directly to the body holsters.

A. further object is to lprovide a system of bracing in the car frame, which will resist lateral and longitudinal strain.

The invention consists generally in an iinprovidcd car traine. e

Further,- the invention consists generally in improved uieans for locking the buckets in their horizontal position.

Further, the invention consistsI in improved means :for tripping the locking means.

Further, the invention consists in means for bracing the side frames against'. inward pull and distortion.

Further, the invention consists in various coi'istruetions and combinations all as hereinafter described and particularly pointed out in the claims.

ln the accompanying drawings, forming part of this spociiioation, Figure 1 is a. perspective view of a dumping far, embodying my invention, showing the buckets in their normal horizontal position, Fig. 2 is a sinular view, illustrating the buckets in their dumping position, Fig. 3 is a detail view, partially in section, illustrating the nieans for looking the buckets in theirhorizontal position, and the mechanism for tripping the locking means, Fifi'. 4 is a similar view, showing the locking mechanism in its releascd\or tripped position, Fig. 5 is a detail view oi one of the. locking latches.

ln the drawing, 2 represents a car frame, having trucks 3. Upon each side of the car I iti-oxide lower side sills 4C composed preferably of channel bars, placed back to back I oi the car.

and riveted together. An arched ltrussy frame, forming the upper side sills of the .ar is provided on .each side, as indicated by the reference numeral 5, and also coinposed of Vchannel bars placed back to back and riveted together. The upper portions of each side sill 5 is Substantially horizontal above the middle portion ot the car and the ends of the side sills are turned downwardly at a suitable angle and secured to the car iframe andthe lower side sill, producing the desired truss etlect. Braces o of angle hars, having llanges placed back to back, are inserted between the horizontal portions oil the upper side sills near the point where the angles are formed therein and their lower ends are secured above the body bolster in position to transmit thereto the load carried by said upper sills. Gusset plates 6 are interposed between the channel bars, co1nposing the sills 5 and the angle hars 6 and securely riveted thereto, thus forming a rigid, substantial construction on each rlfransverse web plates 'T are secured to the 'inclined portions of the sills 5 and extend across the car and have flanged edges, which serve to stilen the web. Gross tie lateral braces 8 and S connect the angles (Sand the web plates 7 respectively with the under :traine of the car. in upright post 9 connectssithe web plete 7 and the body bolster. Between these side trames, so formed, I arrange buch "s l0 lo and will refer to them :and their rmneclions by the same reference numerals with Vthe addr tion of the exponent ait are con'iposed oit' sheet metal, having truunions ll resting upon ,the sido frames directly above the braces o so 'lhni the ioad willige transmitted through the truss trame and braces to the bolster, and each bucket is composed oi" sheet inetai formed with the lines of its joints all running towarffl the dumping end of the bucket, the lower por tion being constructed to drop down between the wheels, as will he set forth more in de tail in in v companion application hereuib` filed July l5), 190D, Serial'No. 508.494.

It will be understood thai ther-ar is pruvided with a bucket on nach side of iis transverse center, the buckets being simile. ly mounted and each having :i lori-:ing device and a fluid pressure controlled mechanism for operating the same.

These buckets i The trunnions are so mounted on the Source of fluid pressure supply. Then this buckets that they will be on the inner side pressure is admitted to the cylinder beneath of the vVertical transverse plane of gravity, the piston., the piston head 'will be pushed so that normally the -buckets will swing-to upward and dui-iii its initial movement, the

A vertically sliding bar movement, whenl further upward movement 15 ais provided on each side of the car having of the piston head will tilt the buckets to 15 lugs 16 thereon, which are adapted to drop discharge their contents. lVith this appa- 30 down outside the free ends of the locking ratus, therefo1e,the intial movement ot' the latches and hold. them in their vertical or piston head will trip the locking device to A locking position. The bar l5 has a slot 17 release the buckets, while the suhsecpient therein for a guide pin 18 and when the bar movement ot' the piston head will tilt the is raised a distance'equal to the length of vbuckets to discharge their load.
