lb all whom. it may concern."
3e it known that I, WILLIAM l. Barrannonr, a citizen of the United States, residing .at Bettendorf, in thecounty of Scott and of dumping cars, and particularly -to'that.
type of dumping cars, whose bodies are .adaptedto be lifted from their trucks.
The objects of my invention are to provide such a construction of the body-bolsters that the tilting of thecar-body can be ac-' com lished without afiecting the relation of the ody-bolster to the truck-bolster, and so.
that when tilted the body will main- .tainedin its tilted position by the automatic actionoia gointed strut or brace, and so that when thisrace is broken and the car resumes itsnor'mal vertical position, it fiwlll be mamtalned and locked in said position byhooks that automatically engage the ends ofs'tfhel cradlespart of the bodybolster.
This I accomplishgtiy the means hereinafter described and "as particularly pointed out in the claims; v v
In the drawings :-.-'Figure 1 iso planview of the underside. of one half of a dump car embodying my invention. Fig 2 ice transverse vertical section taken on dotted line-2, 2, Fig. 1.
innerside extends, in the horizontal plane of the floor of the car, inward toward the body-bolster, to a point about midway be tween the transverse plane of the pivotof the truck and the end of the car, and its rear edge portion is provided with a depressed seat in which the lower flanges of the ceniersills are seated and suitably secured so'that Fig. 8. is a View similar to Fig 2 showing the-ear in its tilted position. Fig 4 The end-sills are, preferably, made their. upper surfaces are in the same plane as the upper surface of said extension 0.
The body-bolster comprises two parts, which may be the bolster proper and the cradle..: Thebolster consists, preferably, of a transverse cast metal beam extending from side-sill to side-sill of the car, the central'part of which is rectangular in cross section and tubular and the portions between this central part and its ends are channeled and thetlower edges of the side-walls of said channeled portions are flanged inward. The top of this bolster proper consists of a flat upper plate, D, the upper surface of which is in the same horizontal plane as the upper surface of-the upper flanges of the center-sills and'side-sills, and the lower portionthereof has its parallel sidewalls d separated a distance less than the width of said top-plate, D, and'is bellied downward so that the depth thereof is greatest at its center of length and so that the lower side thereof is curved to enable it to rock from one side to the other on its lower edges. The lower side edges of said bolster are provided with recesses E, which are, preferably, arranged in pairs'in the same transverse plane, and so that the pairs will be equal distances apart. The center of length of the upper portion of this bolster is provided "with a suitable transverse depressed seat f of suiiicient dimensions to permit the passage of the center-sills, that is of such depth that the upper surfaces of the upper flanges of'said sills-will be-in the same horizontal plane as the upper surface of the bolster.
The ends of the bolster are seated upon the inturned lower flanges of the Zbar side-sills, and are suitably secured thereto by rivets or otherwise. and the floor. G of the car, which consists, preferably. of a. single sheet metal plate, extending from end to end and'sidc to side of the ear, is riveted to the center-sills. the side-sills and lwlsters of the underfranw.
The bolster rests upon and is seated in a cradle consisting of a transverse channeled beam H, the bottom plate or web of which extends in a straight horizontal plane (min end to end,'and is n-uvidr-d at in inner angles of the lower flanged edges of its sidewalls with protuberanciis that constitute. teeth orxcogs 9 that are adapted to be engaged by the recesses E in the lower edges.
of the bolster, I prefer to arrange these opposite side of the center of the bolster .cogs g and recesses E so that there will be will straightgnout, and its knee-joint will one at the center of length of the bolster -move slightly beyond -the-dead center, at in the longitudinal plane of the king-bolt which point, it will be held by the arm 7r: oitthe truck, and an equal number between, of then per member, J, engaging the lower t-hfifi'llilfi and the ends of the bolster. Thus, limit o the diagonal slot j of'the link I, "when the car is in its normal verticalposi" .and propup the raised side of the car. tion the central cogs and recesses will be in When it is desired to restore the car to its engagement, and when the car is tilted the normal horizontal position, shaft a is rocked o engagement of said cogs and recesses will so thatarm'h pulls'linkl toward the adprevent the car-body from slipping upon jacent side of the car,- and the latter, pulling said cradle H and thus injure their proper Jon the upper member-90f the brace, moves relation. At its center of length the cradle it outward and breaks thev joint, and the has a suitable male center-bearing 6 made a Weight of the car causes it to gravitate to 15 integral with and depending from its under its normal vertical'position. -When rocksurface that is adapted to engage a suitable shaft a is thus moved, the brace'breaks and female bearing'of any oft-he'usual'types of doubles into the position shown in Fig. 2 car-trucks. of the drawings.
