nessee Application November 23, 1951, Serial No. 257,836 8 Claims. (Cl. 2241-34) This invention relates to improvements in containers, and more particularly to the type of containers used for trash, garbage, and other refuse.

It has been customary to handle refuse containers with transporting and dumping equipment of the types set forth in the patents of George R. Dempster, No. 2,281,183, April 28, 1942, and No. 2,369,722, February 20, 1945, as examples of such equipment. Such containers customarily are filled while sitting on the ground or on the floor, street,etc., and thereafter may be picked up by the transporting and dumping equipment on a motor vehicle, on which the container may be transported to the point of dumping, the contents discharged, and returned or hauled to the point of re-use. Frequently, a considerable quantity of liquid may be received in the container, especially when hauling garbage and other materials, but when the container has a drop bottom as in Patent No. 2,369,722, and is tilted forward on the vehicle in its transport position, the liquid spills out. Furthermore, some of the liquid may leak out at the point of filling and contaminate the spot around the container so as to be highly ob jectionable in service.

One object of this invention is to retain a considerable quantity of liquid within the container while sitting in its position to be filled, and then later, when the container is raised and tilted forward on the transporting equipment in its carrying position, the liquid is retained in the container without danger of leaking out.

A further object of the invention is to provide a container adapted for use with transporting and dumping equipment, which may be filled when sitting on the ground or on a floor surface, and may be dumped to discharge the contents thereof in a practical manner by such an equipment and yet is so constructed as to retain a considerable quantity of liquid in the container without loss by leaking out either during the setting of the container in its filling position or during transportation to the point of dumping.

Still another object of the invention is to improve the construction of containers of the character described to provide for the effective closing of an open side to retain the contents in the container, and yet will allow ready dumping thereof by tipping the container without the necessity for turning it over in an upside down position. Still another object of the invention is to improve the door structure and latch means therefor of a container, to provide an appreciable opening for the discharge of the contents and yet may be retained securely in closed position for confining the contents in the container. I

These objects may be accomplished according to one embodiment of the invention by constructing a container with a closed bottom, provided with a sump therein, and which bottom is rigid with the side and end walls but has one side substantially open. Doors are provided for the latter side for effectively closing said opening to confine the material in the container, and yet may be released readily for discharge of the contents, for which purpose the doors fold back upon themselves to expose substantially the entire open side of the container. When closed, the doors are effectively latched to confine the contents without danger of discharge except when desired. Additional doors may be provided if desired in the top and ends of the container.

This embodiment of the invention is illustrated in the accompanying drawings in which:

Fig. l is a side elevation ing equipment showing the container in place thereon in transport position;

Fig. 2 is a similar view ing position;

Fig. 2a is a similar view of the container showing a wider opening door;

Fig. 3 is a perspective view of the container removed and with one of the doors open;

Fig. 4 is a similar view showing additional doors in open position; i

Fig. 5 is a similar view showing the side doors open;

Fig. 6 is an end elevation thereof; and

Fig. 7 is a side elevation thereof.

The invention is shown as applied to transporting and dumping equipment of the character generally represented in the Dempster Patent No. 2,369,722, February 20, 1945, merely as an example of the type of equipment in connection with which it may be used.

This transporting and dumping equipment includes a motor vehicle chassis generally designated by the numeral 1, upon which is mounted a hoisting unit, comprising a sub-frame 2 having a container rest generally indicated at 3 mounted thereon and inclined forwardly of the motor vehicle. Boom arms are shown at 4, pivotally mounted at 5 at their forward ends to the sub-frame 2 and adapted to be raised and lowered by a hydraulic hoist 6.-

A skit frame is shown at 7 mounted on the sub-frame 2 for bodily movement lengthwise relative thereto between the positions shown in Figs. 1 and 2. Suitable means is provided for moving the skid frame 7 forward and rearward of the chassis, as described more fully in the Dempster patents referred to above. The free ends of the boom arms 4 support the container by flexible devices such as chains 8, attached to the boom arms at 9 to raise and lower the container to and from its dumping position. The skid frame 7 is also provided with a dumping hook, generally designated at 10, to be engaged for dumping the container in the position shown in Fig. 2.

The foregoing transporting and dumping equipment, generally as described above, is set forth and disclosed more fully in the Dempster patents referred to, particularly No. 2,369,722.

The container illustrated as an embodiment of this invention, for use with the transporting and dumping equipment, is shown diagrammatically in Figs. 1 and 2, and more fully in Figs. 3 to 7 This container is constructed preferably of sheet metal of relatively heavy gauge, according to the size and capacity of the container and the material to be contained therein, but is substantially of rigid unitary structure. End walls are shown at 11; a side wall at 12; and a bottom at 13, all being formed of suitable steel plates or the like, rigidly connected together as by welding, or other fastening means. The bottom 13 is provided with an upwardly inclined portion 14 at the edge thereof opposite from the side wall 12, preferably having a reinforced lip generally indicated at 15, and coacting with the end and side walls 11 and 12 to form a closed sump in the bottom of the container having a liquid level generally indicated at L" in Figs. 1 and 6 at the free edge of the lip 15. In the example illustrated, a top wall is shown at 16, although the top of the container may be partially or entirely open, as desired.

The side wall 12 is provided with a vertical indentation 17 therein, adapted to receive within the confines thereof a bail 18, shown as pivoted at 19 to the bottom 13 of the container. The upper end of the bail 18 is adapted to engage the hook 10, as shown in Fig. 2, to facilitate dumping of the container.

Lifting pins are shown at 20 on the respective end walls of the container, for detachably engaging the free ends of the chains 8 to lift the container from its filling position on the ground, or other surface, onto the skidway 7 and to hold the container in dumping position, as well as for handling the container generally. The chains 8 extend from the lifting pins over deflectors 21,

showing the container in dump- Patented Feb. 15, 1955 of a transporting and dumpsecured to the ends 11 of the container at points above the lifting pins 20 and adjacent the side wall 12 so as to ensure of proper support for the container by the chains.

The end walls 11 are shown as provided with doors 22 hinged thereto for opening and closing action, and additional doors may be provided in the top 16, as indicated generally at 23. These doors 22 and 23 are shown as hinged and adapted to be latched in closed positions by suitable latching means.

The open side of the container opposite from the side wall 12 is adapted to be closed by a pair of coacting doors, generally indicated at 24 and 25. The door 24 is hinged on a rod 26 to the body of the container for swinging movement to a raised position, as shown in Fig. 5, and preferably has suitable balancing springs 27 connected therewith and tending normally to move the door 24 to its open position when released. The door 25 is hinged on a rod 28 to the free edge of the door 24, so as to be free for swinging movement either to the open position shown in Fig. 4, or with the door 24 to the open position shown in Fig. 5. Springs are shown also at 29 on the hinge rod 28, normally tending preferably to move the door 25 to its open position with respect to the door 24.

Suitable latch means is provided for securing the doors in their closed positions, either at one or both opposite ends of the container, as may be desired. The hinge rod 28 is shown as extended beyond the end of the container,

and is provided with a hook catch thereon, indicated generally at 30, in position to engage a pin 31 projecting outwardly from the adjacent end wall 11 of the container. A handle 32' is shown attached to the hinge rod 28 to turn the latter and move the catch or catches 30 to their released positions. One or more springs 33 are connected with the hinge rod 28, normally tending to rotate the latter to move the catches to their engaged positions with the pins 31. i

A latch rod 34 is journaled on the free edge portion of the door 25, extending lengthwise thereof, and is provided with catches or engaging hooks 35 on one or both opposite ends thereof, preferably both ends, to engage pins 36 projecting outwardly from the end walls 11 of the container. One or more springs 37, connected with the rod 34, tend to rotate the latter in a direction to cause engagement of the hooks 35 with the pins 36. A handle 38 on the rod 34 may be manipulated to turn the rod and release the catches 35. A lock may be provided for each catch 35, as indicated in Figs. 3 and 6, particularly, and designated at 39. This lock is in the form of, a bar pivoted at 40 on the end wall 11 of the container in posi- I tion to be moved into engagement with the top face of the catch 35 in its engaged position with the pin 36 to prevent accidental separation therefrom, and yet may be released when desired.

Upon disengagement of the catch or catches 35 from the pins 36, the door 25 may be moved to its open position, as shown in Fig. 4, relative to the door 24, automatically if spring loaded by the action of the springs 29. Latches are shown at 41 on the door 24 in position to be turned to the dotted line position shown in Fig 7, to engage over the free edge of the door 25, in open position, as in Fig. 4, and hold this door in its open position.

Then, upon disengagement of the catches 30 from the pins '31, the doors 24 and. 25 will swing on the hinge rod 26 to the open positions shown in Figs. 2 and 5, for dumping the contents, thus opening the entire side of the container if required. although it will be evident that the container may be dumped with only the door 25 open, as in Fig. 4, especially where the contents are substantially entirely liquid, or the container is only partially filled.

Torsion springs of substantial tension may be used at 27 sufficient to move the doors 24 and 25 to wide open positions as illustrated in Fig. 2a. This will avoid any tendency of the doors to impede dumping of the container.

It will be evident that the sump provided in the bottom of the container will contain therein a substantial quantity of liquid, not only during filling of the container when it is at rest on the ground. but also when it is raised and tilted forward on the skid frame in carrying position, thereby transporting a substantial quantity of liquid material without spillingthe liquid during transportation to,

wet and contaminate the street.

The hauling and dumping of the container will be evident from Figs. l and 2, and are set forth more fully in the. Demp'ster patents referred to above. It will be evident, however, from Fig. 2 that the type of container herein set forth provides for dumping the contents preferably away from the rear of the truck, which means that the truck could back close to a bank or other edge and dump over it without the necessity for getting too close so as to Create a danger or hazard. This is made possible by the construction of the container as well as the use of an L-shaped bail' 18, which is retained against a stop on the skid frame.

While the invention has been illustrated and described in one embodiment, it is recognized that variations and changes may be made therein without departing from the invention as set forth in the claims.
