SPECIFICATION forming part of Letters Patent No.-634,684, dated October 10, 1899.

l Application tiled February 17,1899. Serial No. 705,856. (No model.)

To all 'wiz/0m it may concern:

Be it known that I, MoRToN G. BUNNELL, a citizen of the United states, rcsidng'at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Dumping-Cars, of which the following is a specification.

Objects of my invention are to provide a' simple and efficient construction of dumpingcar involving a comparatively lowdown, normally-balanced, easy-working, and self-'righting oar-body, to permit such car-body to dump at one side of they track, to simplify the arrangement of gates for opening Vand closing the dumping-receptacle formedby the tilting body, and to permit thebody to tilt without tilting either of the gates employed, but at the same time to shift the gates sidewise synchronously with its bodily side movement, so as to maintain such gates in determinate relative positions suitable for closing the open sides of the body when the latter is righted or in its normal horizontal position. 'y

To the attainment of the foregoing and other useful'ends, the car-body forms a recepof the bodily s'ide movement of the body, but` will not -rise or partakeV of the tilting action ofthe body. In this way the gates 'are per! maneutly down regardless of the position of the body and are at all times in place to close the sides of the body when the latter isl righted or in its nor-mal horizontal position.

vIn the accompanying drawings, Figure 1 represents in end elevation a dumping-car embodying the principle of my invention. Fig. 2 is a like view showing the car-body in position for discharging the load at one side of the car-track. Fig. 3 representsthe car in side elevation.

The tilting oar-body A, which is adapted to provide a suitable receptacle for the load,

is constructed with ends a a and a suitable bottom, but is open at its longitudinal sides-n that is to say, the sides usually present in the tilting body and commonly formed by or involving movable` side gates are not present.

In place of such movable side gates I arrange as fixtures upon or part of an independent frame B a eoupie of oppositely-arranged and longitudinally extending side gates O O, which are formed and positioned relatively to the tilting body toclose the open sides of the latter and constitute sides or gates therefor when such tilting body is in its normal horizontal position, as in Fig. l. The tilting body is arranged to tilt about a horizontal longitudinal axis passing through the center of each of its two ends, and for such purpose it is pivoted or trunnioned in transverselyarranged end bars or plates b, which, together withthe gates O O, constitute a frame or earrier. The end edges. of the end portions a of the tilting body swing in the arcs of a circle having as its center an axis passing centrally through the trunnions, andhenoe to adapt Athe gates O upon the carrier B to effectively close the open sides of the tilting body when :the latter is in its normal horizontal position the gates O C and the end edges a of the end portions a a of the tilting body are formed on 'curves corresponding with the aros of said circle.

The frame or carrier B, which comprises and carries the gates, is arranged for horizontal side movement, either way, upon the oartrack, and ispreferablyguided and supported by grooved rolls D, which engage and traverse ,suitably-formed guides or rails E extending transversely across the car-truck at or near the ends of the latter. These guides extend somewhat beyond the sides of the car-truck, so as to permit the carrier tobe shifted to one side'to an extent suitable' to allow the car- ICO rocker-base having its curved bearing-face on the arc of a circle having as its center an axis extending centrally through the trnnnions, the preferred arrangement being to divide-the rocker-base into two or more comparatively large rockers F, arranged to bear and rock upon the truck-frame. As a matter of simplification and further improvement the baseiianges c of the guide rails or'bars E can provide bearings for the rockers, and to avoid slip the rockers have notches f, corresponding with and adapted to receive teeth @f on the base-flanges of the bars E or the converse thereof, as may be desired.

The carrier I3 or the tilting car-body A can be provided with an y suitable construction of latch or catch means for locking the tilting body in a horizontal position-as, for example, the carrier may have on each gate `C a rock-shaft Gr, provided with catches g, which engage under the side-edges of the bottomof the tilting body when the latter is ina horizontal position. These catches can be normally maintained in `position to thus engage the tilting body by means of springs II, suitably applied to the rock-shafts,and the catches can be suitably beveled and arranged so that their action shall be automatic-that is to say, after the load has been dumped and the body is ytilted back to its normal horizontal position a side edge of its bottom Will during such return movement lof the body strike and momentarily force back the catches at one side of the carrier, so as to allow such edge ot the body-bottom to pass.

The tiltingV body is normally balanced whether empty or loaded, and when loaded it can be easily tilted as a result of its balanced condition, and by reason of the arrangement hereinbefore described said tilting body will be comparatively low down when in a horizontal position, thereby permitting it to be loaded and manipulated with ease and also insuring safety during transportation. It Will also be seen that While the tilting body is thus set comparatively low down I attain a maximum extent of combined bodily side shift and tilting movement. In order to dump the load, it Will only be necessary to unlock or unlatch the tilting body at one side of the car either by manually operating the catch device at one side or by tilting the body with sufficient force to cause it to automatically operate such catch device, and thereby'eftect its releasement therefrom. As the weight of the tilting body is sustained by the car truck intermediately through the rocker-base or rockers and as the rocker-base has its bearing face or faces on the are of a circle of comparatively large radius,the body can be easily tilted. When the tilting body is thus tilted, it will have a bodily side movement,combined With a tilting action, and will cause the laterally-shifting frame or carrier, which is provided with the gates C C, to move to one side to an extent proportional to the bodily side movement of the tilting body.

lVhen the tilting bodyis thus tilted, it leaves the said gates C C as in Fig. 2, and hence it willopenanddischargetheload. Afterdumping the tilting body will right itself, it being seen by Fig. 2 that after the discharge the greater portion of the weight of the tilting body will be between a vertical plane passing centrally through its trnnnions and the middle portion of the car-truck. In this Waylittle or no help will be required in righting the car-body, which latter in tilting back to a horizontal position will cause the carrier to shift back in place upon the car-truck.

l/Vith further reference to the means herein employed for opening and closing the sides of the tilting car-body it will be seen that the gates C C, which close the tilting body when the latter is vin a horizontal position, are connected together by the end bars or frame parts b and are non-tilting and that these mem-bers C and b constitute a rigid or substantially krigid frame or carrier adapted as a Whole for horizontal side shift simultaneously With and as a result of the action ot the tilting body, which is pivotal'ly connected With such frame or carrier. In this Way the gates C, which serve to close the body when the latter is in a horizont-al position, 'have no effect upon the tilting action of the body, which tilts independently of the gates, and hence said gates will in no Wise tend to retard such action and Will not overweightthe body at one or the other side While it is being tilted for the purpose of dumping the load. This arrangement also admits of an extrem ely simple construction.

That I claim as my invention is- 1. A dumping-car `comprising a body forming a receptacle open at opposite sides and supported by a rocker-base so as to have a combined tilting and bodily side movement in dumping; and oppositely-arran'ged nontilting, laterally-movable gates relatively positioned to close the open sides of the body when the latter is in its normal, horizontal position; the body being 'connected with the gates to tilt independently thereof but cause them to partake of its bodily side movement, substantially as described.

2. A dumping-'car com-prisinga body form.- ing a receptacle open at lopposite sides and supported -by a rocker-base so as to have a combined tilting and bodily side movement in dumping; Aand a frame or carrier supported to move sidewise upon the truck-frame and comprising a pair of non-tilting gates arranged for closing the open sides of the body when the latter is in its normal, horizontal position; the body being pivotally connected with said frame or carrier at points on a line passing substantially t-hrough the center of each of its ends, substantially as described.
