To aLZZ whom it may concern:

Be it known that I, JAY B. RHODE`S, a citizen of the United States, and a resident of' Harvey, Cook county, Illinois, have invented a certain new and useful Improvement in Dumping-Cars, of which the following is a specification.

My invention relates to dumping-cars of that type in which a tilting box or body is provided at each sid'e with an'automaticallyopening gate or side-board. The said body is usually mounted to tilt about a longitudinal axis, so as to allow either side to be tilted v down for the purpose of discharging the load. The said gates or side-boards are usually connected with the truck in such manner that they operate automatically. If the box or car-body tilts to the right, the gate or-sideboard at that side is automatically lifted, so as to cause the load to be dumped at the right of the car, and, vice versa, if it is desired to dump the load at the left of the car then the body is tilted to the left and the gate or side-board at this side is automatically opened, while the other gate or side-board remains closed.

Generally stated, it is the object of my invention to provide a simple and efficient construction of dumping-car of the foregoing character.

A special object .is to provide improved` means for locking the box or body in a horizontal position.

Another object is to provide an improved form of gate or side-board which will operate easily and withoutV danger of breakage and which will release the load more quickly than heretofore and at the' same time to so organize and combine the said lockingr means and gates that the latter will be held positively and securely against any upward movement until it is desired to discharge the contents of the car-body. y

A further object is to provide an improved and more efficient connection between the gates or side-boards and the truck and to thereby secure greater certainty in the automatic opening and closing of the gates or sideboards.

It is also an object to provide certain details and features of improvement tending to increase the general efficiency and to render Serial No. 103,992. (No model.)

' a dumping-car of this type more serviceable and reliable in use.w Y

To the foregoing'and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure lis an end elevation of a dumping-car embodying the principles of my invention, the car body or box being shown tilted to one side in dotted lines.A i Fig. 2 is a side elevation of the dumping-car shown in Fig. l. Fig. 3 is a detail perspective illustrating one of the jointed connections between the truck and the gates or side-boards. Fig. 4 is a similar detail perspective illustrating a portion of one of the connections `between the gates andthe truck and showing the hook which descends and automatically engages theprojecting lug in a horizontal position. Fig. 5 is another detail perspective illustrating a'portion ot' one of the articulated connections between the truck and the props for automatically opening and supporting the gates or sideboards. Fig. 6 is a detail perspective of one corner of the car body or box, showing one 'of the lugs or projections of the lower edge of the side gates and also showing one of the Ysockets or openings whicliare formed in the bottom of the car-body and which are adapted to receive the said lugs or projections.

As thus illustrated my invention comprises, preferably@ suitable car-truck A,constructed with suitable wheels a. .The receptacle, or, in other words, the car body or box B, is preferably mounted upon and supported by the said car-truck.Y In orderthat the said box or lreceptacle may tilt to either side, so as to dump the load at either side of the truck, the connection between the box B and the truck A preferably consists of a number of hingelike orpintle bearings C. These pivotal connections, it will be seen, permit the car body or box to tilt about a horizontally and longitudinally extending axis. The said body or box is adapted to carry the load and is prefably provided with automatically-opening gates or side boards D. When the, body-is in a horizontal position, as shown in Fig. l, these gates or side boards retain their posiclose the open sides of the box or receptacle.

shown in Fig. 3, so as to lock the body or box,

tions at each side of the car, so as to normally f IOO Each gate or side board can be pivoted to the outer ends of the arms d, which latter have their inner ends pivoted to the end walls of the box at d. In addition to this arrangement each swinging arm d can be connected with the truck through the medium of the props or supporting members (Z2 and also through the medium of the jointed or articulated members E. Preferably each of said jointed or articulated members consists of a pair ot' parallel bars e e and also of a third bar c. Constructed in this manner each articulated or jointed member is adapted to open and close like a jackknife, so to speak, each bar e' being adapted to swing down between the two bars e c. Each pair of bars e e is preferably pivoted to the truck at e2 and pivotally connected at the other end with the bar e. The outer end of each bar e is, it will be seen, pivot-ally connected with the lower end4 of one of the pendent props or supporting members d2. With this arrangement each gate or side board is provided with a pair of props or supporting members adapted to support the gates or side boards when the body is tilted to one side. For example, should the body be tilted to the right, as shown in Fig. 1, the articulated or jointed members at the left permit the props at that side to rise freely with the upward movement of the lefthand side of the car-body, while the props at the right bear down upon the pivotal connections c, and consequently the right-hand side of the car-body moves down, while the gate at that side is supported or upheld. If it be desired, however, to dump the load to the left, then the left-hand gate would be held up or supporledinasimilar manner,while the righthand gate will rise and remain in place to close the open side of the box or body.

In order to enable the gates or side-boards to properlyhold the load against discharging while the body is in a horizont-al position, each gate or board is preferably provided with lugs or projections d3, adapted to engage sockets or openings d4 in the bottom of the car-body. With this provision the pressure of the load cannot crowd the gates or side.- boards outward-that is to say, cannot force or swing the gates outward about their pivotal connections with the arms d. However, as soon as one side of the car-body moves slightly downward, so as to release the projections d3 from their sockets, then the gate thus released is free to swing about its pivotal connections with its arms d, thereby allowing a partial discharge of the load upon the initial movement of the gate. This has the further advantage of allowing the gate t-o immediately upon starting open swing away from the load, thereby clearing itself from the load in a manner to make the remainder of its opening movement comparatively easy and less likely to cause breakage. In other words, should the car be loaded with sharpedged rocks, the edges of which might impinge upon and tend to prevent the gate from opening, the gate to be opened will in such case swing clear of the rock upon the initial opening movement, thereby clearing itself of anything which might tend to resist its opening movement relatively to the box or body.

The articulated or jointed 4members E cause the lower ends of the props d2 to always descend and rest upon the joints or pivotal connections e2. In other words, the bars c serve as guides for the bars e', causing the latter to always swing downwardly and rest in the same place. In this way loose joints in the articulated connections between the gates and the car-truck will not tend to produce any uncertainty in the automatic operation ofthe gates, it being observed that, as stated, the articulated members E will, even though the joints be somewhat loose, always bring the lower ends of the props into their proper resting-places, as illustrated.

As a simple and effective arrangement for locking the car-body in a horizontal position, as would be necessary in loading and carrying a load, the lower ends of the props or supporting members d2 can be provided with pivotally-mounted hooks F. Each hook, it will be seen, is provided with a portion f, adapted to engage and hook undera projection j", involved in the pivotal connection e2. Furthermore, each hook is preferably provided with a handle portion f2. Thus mounted and formed these hooks are adapted to automatically lock the body or box in a horizontal position, as shown in Fig. 1. If it is desired to tilt the box to the right, as shown in Fig. l, then the handle portions f2 on the hooks at the left can be grasped, and the upward pull on these handles will then not only release the hooks from the projections j", but will also tilt the car over to the right, as shown. Thus these locking hook-like members F not only serve as locking devices, but also' as handles by which to tilt the box or receptacle. Inadditiontheselockingdevices are, it will be seen, applied to the articulated connections between the gates and truck. Hence the means for automatically opening and closing the gates are rendered capable also of automatically locking the car-body against tilting movement.

Thus it will be seen that by my invention I provide a dumping-car operating upon a different and more satisfactory principle than heretofore and involving a simplified and more eiicient construction. The new mode of operation renders the automatic action of the gates more satisfactory in use, and the pivotal connections between the gates and their swinging arms not only, as stated, facilitate the discharge, but also enable the gates or side-boards to clear themselves from the load. In this way the bottom portion of each gate or side-board can first swing outward Linder the pressure of the load, and after swinging clear of the load can then rise freely and without danger of breakage. `Furthermore, as explained, the car-body can be prac- IOO IIO

tically simultaneously lthat is tosay,

unlocked and,tilte d--'l l the effort:l made' by the operabody is also utilized fory to one side. The hooks or locking devices F at each side of the car can be connected by :rods F'. In this way both hooks at one side of the car can be operated by grasping the handle of either one.

In returning to its horizontal position the hooks or locking devices automatically lock the car in such horizontal position. In this way the means for actuating the gates and the means for locking the car in position are combined in a way unnecessary to employ separate devices for the two purposes. In other words, the props d2 serve not only as a means for tilting up the gates relatively to the body or box, but also as stays or tie-rods for holding the car-body in its normal position. In this way my improved arrangement obviates the necessity of employing independent or additional means, such as chains or other like devices, for holding the car in its normal position. Furthermore, it will be seen that with the construction and organization shown and described I provide a pair of gates or displaceable sideboards which when the gate is in its normal or horizontal position are locked positively and securely against any upward movement whatever. Thus the gates, although pivoted so as to instantly swing outward upon a slight tilting movement of the car-body, are at the same time so locked and held down in place by the locking devices applied to the foldable props that neither oneis liable to release its lower edge from the iioor of the car-body. Consequently, and as will now be apparent, I rovide locking'devices which perform a double function, so to speakfthat is to say, they not only lock the car-body against a premature or undesirable tilting movement, butalso tie the gates or displaceable side-boards down in place until the proper time for dumping. Practically, then, I provide locking devices which are preferably applied to the foldable props and which in preventing thelatter from unfolding serve-to normally tie lthe pivoted and displaceable side-boards to the truck. In this way the catch devices for locking the lower edges of the gates or side-boards to the car-body are locked against loosening by the locking devices applied to the articulations of the foldable props.
