FIELD OF INVENTION
This invention relates to a self-dumping container which is operated in combination with a powered vehicle.
In particular, this invention relates to a self-dumping container which is operated in combination with a fork-lift truck.
BACKGROUND OF THE INVENTION
There are various types of containers and container attachments with unique dumping mechanisms. However, these containers and/or attachments tend to be complicated and expensive devices which can be difficult to operate. For example, United States Patent 4,838,752 to Bryant describes a safety mechanism for a fork-lift attachment that prevents the premature dumping of a container. This patent relates specifically to a dumping mechanism for a container rather than a container having a self-dumping mechanism. This patent shows a dumping container having a frame adapted to be mounted on a fork-lift truck and having release means. Hydraulic means are required to release and tilt the container.
United States Patent 3,877,593 to Sleziak discloses a container in which the container is supported on a base member having fork-lift pockets. The base member is pivotally mounted to the container at one end of the base member thus placing the pivot point on the forward end of the container. This container is not self-dumping since the fork-lift mast must pivot forward to initiate rotation of the container.
United States Patent 4,385,860 to Corbin discloses a barrel handling and dumping device for use with a fork-lift truck. The device has a barrel support plate to which is hinged a base member for mounting on a fork-lift. The device is further directed to handling of open topped receptacles. To dump a barrel carried by the support plate the truck is advanced 2 0 2 ~
to bring an actuating arm beneath a projection on a bin in which the contents of the barrel is to be dumped, and the fork is raised to bring the actuating member in engagement with this projection and then advanced and raised to invert the barrel. Set screws are required to tighten the plate to the forklift and each receptacle must be anchored to the tilt plate.
The prior art, as illustrated above, is often complex in construction and requires several steps to effect dumping. The container of the present invention is self-dumping and simple to operate.
SU~IARY OF THE INVENTION
The present invention pertains to a self-dumping container adapted for attachment to a prime mover. The self-dumping container comprises a base member adapted for detachable connection to the prime mover and comprising a frame including means for engagement by the prime mover and container means pivotally secured to the base member for movement between a loading position in which the container means is locked onto the base member and an unloading position in which the container means is unlocked with respect to the base member and swings about the pivotal connection to dump the contents from the container means. Locking means are provided to retain and release the container means with respect to the base member. The self-dumping container also comprises means for remotely operating the locking means.
Pivot means between the bottom wall of the container means and the base member are located to one side of the horizontal pivot axis of the container means whereby, when the locking means is released, the container means automatically swings to the unloading position.

Figure 4 is an enlarged view of a preferred embodiment of the pivotal connection; and Figure 5 is a perspective view of the self-dumping container of the present invention in its unloading position.
DESCRIPTION OF THE PREFERRED EMBODIMENT:
Referring to Figures 1 and 2, the self-dumping container 10 of the present invention comprises a base member 12 and a container member 14 which are pivotally secured to each other.
The base member 12 is U-shaped and comprises two spaced apart and parallel channel members 16 and 18 attached together by a cross-member 20 as illustrated in Figure 2. The fork members 22 and 24 of a forklift truck 26 as illustrated in Figure 5 are adapted to extend into the channel members 16 and 18. The base member 12 further comprises a pin lock 28 secured to the upper surface of the cross-member 20. An actuating handle 30 and a pin lock return spring 32 are secured to the pin lock 28. A rope 34 can be attached to the actuating handle 30 to allow easy actuation thereof.
The container member 14 has side walls 36 and a bottom wall 38. A latch pin 40 is secured adjacent the lower edge of the side wall 36 and is adapted to be 2~2~50~
engaged by the pin lock 2~. Four longitudinally extending reinforcing ribs 42,44,46 and 48 of rectangular cross-section are secured to the bottom wall 38 of the container membe- 14. The first pair 42 and 48 is located along the marginal edges 50 of the bottom wall 38 while the second pair 44 and 46 is located inwardly of the first pair. One reinforcing rib of each pair (42 and 44; 46 and 48) define a pocket 52 for the channel members 16 and 18. A pin and bushing arrangement 54 offset with respect to the horizontal axis of the container member 14 secure the channel members 16 and 18 between rib members 42 and 44 and 46 and 48 respectively so that when the pin lock 28 is released, the container member 14 will automatically swing to the unloading position. In an alternative embodiment, the container member 14 has only one pair of longitudinally extending reinforcing ribs located along the marginal edges of the bottom wall and the channel members are pivotally secured to the container member by means of a pin and bushing arrangement, which bushing extends from one marginal edge of the bottom wall to the other.
In a preferred embodiment, torsion springs 56, as shown in Figure 4, mounted on either end of each pin and bushing arrangement 54 control the movement of the container member 14 from its loading to its unloading position. The side walls 36 of the container member 14 can be made of corrugated metal as illustrated in Figure 1, allowing for the construction of a lightweight container member 14 of increased strength.
In use, the container member 14 and base member 12 are secured to each other by means of the pin lock 28 and latch pin 40 and the container member 14 loaded. The base member 12 is then engaged by the forklift truck 26 by introducing the fork members 22 and 24 into the channel members 16 and 18. If desired, as an additional safety feature, the base member 12 may be further secured to the forklift truck 26 by means of chains 58 or the 2 ~
like. The self-dumping container is then raised off the ground and carried to the appropriate location by the forklift truck 26. Having reached the location at which it is desired to dump the contents of the container member 14, a pull on the rope 34 causes actuation of the actuating handle 30 and disengages the pin lock 28 and pin 40. This causes the container member 14 to rotate forward due to the offset positioning of the pin and bushing arrangement 54, thereby causing the container member 14 to be emptied. If the contents of the self-dumping container 10 are to be dumped in another container, the container 10 is to be raised and moved forward during the unloading operation. The presence of the second container allows for a more controlled unloading operation. The container member 14 is then rotated back to its original position where the pin lock 28 engages the pin 40.
While the present invention has been described in connection with a specific embodiment thereof and in a specific use, various modifications will occur to those skilled in the art without departing from the spirit and scope of the invention as set forth in the appended claims. I wish to embody within the scope of the patent which may be granted hereon all such embodiments as reasonably and properly come within the scope of my contribution to the art.
