DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 233,542, dated October 19, 1880.

Application filed August 16, 1880.

To all whom it may concern Be it known that I, WILLIAM H. PAIGE, of

Springfield, in the county of Hampden and ing my invention applied.

State of Massachusetts, have invented a new and useful Improvement in Dump-Oars, which has not been patented in any foreign country to any person with my knowledge and consent, of which the following is a specification.

The object of my invention is to provide a railway-car from which the whole contents may be easily and quickly dumped from either side by manipulating the mechanism connected therewith, and which is illustrated in the accompanying drawings, in which- Figure I is a side view of a dump-car hav- Fig. II is a plan view of the frame of the same having the mechanism applied. Fig. III is an end view of the car. Fig. IV is a vertical longitudinal section of the car, showing the shipping lever and rod which operates the side bearing, and the clutches which are connected with the winding-shaft, and showing the side bearing thrown up, with the forward clutch thrown out from the winding-drum. Fig. V is a vertical longitudinalsection through the hunter-socket. Fig. V1 is avertical longitudinal section, showin g the clutch-operating rod, which also moves the side bearing, and with the latter in its vertical position. Fig. VII is a front view of the buffer-socket, and Fig. VIII is a front view of the braces between which the buffer-socket revolves, and by which it is held in place.

In the drawings, A represents the two side sills of the car, and O 0 represent two other inside sills or timbers, all extending in a direction lengthwise the car, and to which are secured the cross-timbers and floor-boards of the car, and to the lower side of the car, or beneath the floor, are secured suitable bearings, in which are arranged to revolve easily the shafts 14, one on each side, extending lengthwise the car, on each of which shafts is a drum, 8, arranged to revolve freely on the shaft. Two clutchesone, 6, on one side of the drum, and another, 7, on the other sideare so keyed to the shaft as to revolve only with the shaft, and so as to slide to and fro along the shaft and engage with the drum by teeth or projections on the clutch and also on the sides of the drum, and cause the drum to (No model.)

revolve, according as one or the other clutch is brought up against the drum.

A rod, 2, is arranged to move longitudinally in suitable bearings near each shaft, upon which rod is a projection, 5, to engage with and move the clutch 6 to and fro along the shaft, and also a projection, 9, to move the other clutch, 7, along the shaft in the same manner, and these clutches are so adjusted with reference to the rod2 that when one clutch is in engagement with one end of the drum the other clutch is moved away from the other end, say, from six to eight inches, and the rod 2 at the end of the car is connected with a pivoted lever, 1. This rod 2 is also connected, by an arm, 4, with a pin or arm on the side bearing, D, which is a heavy metallic piece suspended from a shaft or pivot, 20, secured to the bottom of the car, one of these bearings on each side of the car at each end, its lower end resting on the truck-beam and this side bearing, D,is so connected to the rod 2 that when the latter is moved forward to engage the clutch 6 with the end of the drum 8 the side bearing is held in a horizontal position, as shown clearly in dotted lines in Fig. IV; but when the rod 2 is moved back to engage the clutch 7 with the other end of the drum the side bearing, 1), is held in a vertical position, so that the weight of the car and its contents will be supported on that side on the truck-beam, as shown clearly in Fig. VI.

The shaft 14 is provided at the end of the car with a toothed wheel or gear, 11, engaging with a worm or screw on the lower end of the vertical shaft 10, with a winch or handwhcel 011 top, so that by turning the handwheel or the shaft 10 the shaft let beneath the car will be revolved.

A dog, 12, is pivoted to the lower side of the car and is attached to a rod, 15, extending along beneath the car, at the side, which rod is so connected with any desired number of latches, 16, that when the lower end of the dog is moved inward and upward the inner end of the latch will be raised and its outer end depressed, to permit the side wall of the car, which is pivoted at a, to swing outward.

The ear is pivoted at E to the truck at each end, so as to tilt to either side, and the buntor-socket 17 is secured at each end of the car to and between the sills I. This hunter-socket consists of a circular iron, 17, having an annular groove or channel around the outside, into which are fitted so as to move freely the projections 18 of the braces 21, which are bolted one to each sill, at each side the socket l7, and a projection on the iron 17 strikes against oneof the projections 18 when the socket is turned in either direction, to limitthe rotary movement of the hunter-socket to, say, an arc of about thirty degrees.

The rod 2, side bearing, 1), and connections, and operating-lever 1, the shaft 14, and triprod are all duplicated, all these being arranged for each side of the car, so that the latter may be dumped either way orto either side.

Todump the car the operation is as follows: The lever 1 is moved into the position shown in -Fig. IV on the side on which it is desired to dump the ear, raising the side bearing, D, into a horizontal position and moving the clutch 6 up into engagement with the drum 8, and the lever 1 on the opposite side is moved just sufficiently to move the clutch away from the drum on that side, so that that drum will revolve freely and rapidly on the shaft. The hand-wheel on the shaft 10, on the side on which the car is to be dumped, is then turned, revolving the drum and winding up the rope or chain, and thereby drawing down that side ot'the car, (the end of the chain or rope being made' fast to the drum and extendingdown and around a pulley or roll in the truck-frame, thence outward along the truck-frame and around another roll, and upward to theouter sill of the car, where it is made fast,) and tiltiug'the car on its pivots at E. When this windingup of the chain or rope has proceeded far enough to throw the center of gravity of the load outside the pivot E, the lower side of the car will then drop of its own weight, the chain unwinding. rapidly from the opposite drum, and the dropping side striking with a jar against the end F of the truck beam or frame, and the inside sill, 0, also striking against a cushion or block, 22, on the truckframe, just before the sill A strikes the end of the truck-beam at F, too great a jar or shock is prevented. As the dropping sideof the car passes down theend ofthe dog 12 strikes against a plate, 13, on the truck-frame, and the dog is thereby quickly thrown inward and upward,

tripping the latches 16, (of which there maybe mechanism of the car is adjusted to a certain extent the weight of the car or itscontents isutilized to complete the dumping operation, which is accomplishedwith ajar, which will efl'ectually and completely empty the ear, and

this operationand its results differ very essentially from those in which the car is gradually and slowly pulled over, or tilted gradually through the whole movement, and the dumping is made much more effectual.

WVhen the car is tilted back again, by windingup the opposite chains the side of the car swings in again by its own weight, and is locked by the latches 16 automatically by the weight of the dog 12 in swinging down.

If one car is dumped and the next one to which it is coupled remains stationary, the two hunter-sockets 17 will partially rotate between the projections 18, so that all strain on the coupling will be removed, and yet the socket cannot rotate sufliciently far to lose out the link-pin which secures the cars together.

it will be seen that as the side bearing, D, is pivoted at its upper end to the bottom of the car, when its lower end rests upon the truck-frame there will be sufficient movement ofthe bearing-on its pivot as the car isbeing moved upon the road to allow ot' the differences of relative position between the car and its trucks in rounding curves, and yet the load will be fully supported by the bearings. As

the chains are kept wound up on the drums,

and the side bearings are provided with this forward and backplay, there is little or no friction of the bearin gs on the truck-frame, and the car is effectually prevented from be ing accidentally dumped during transportation.

Having thus described my invention, what I claim as new is-- 1. In a dump-car, the combination, with each side bearing pivoted at its upper end to the car, of the longitudinally-moving rod 2, the pivoted rod-operatinglever 1, and the arm 4. connected at one end with said rod and at the other end with the side bearing, whereby the latter is moved into and out of supporting connection between the car and the truck, substantially as described.

2. In a dump-car, the combination, with a winding drum arranged to revolve upon a shaft, of a sliding clutch to engage with either end of said drum, the longitudinally-moving rod provided with projections connected with said clutches to move the latter into and out of engagement with said winding-drum, and the pivoted lever connected to and operating said rod,- substantially as described.
