DESCRIPTION OF THE PREFERRED EMBODIMENTS

(17) Reference will now be made in detail to several embodiments of the invention that are illustrated in accompanying drawings. Whenever possible, the same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps. The drawings are in simplified form and are not to precise scale. For purposes of convenience and clarity only, directional terms such as top, bottom, left, right, up, down, over, above, below, beneath, rear, and front, may be used with respect to the drawings. These and similar directional terms are not to be construed to limit the scope of the invention in any manner. The words attach, connect, couple, and similar terms with their inflectional morphemes do not necessarily denote direct or intermediate connections, but may also include connections through mediate elements or devices. A multi-purpose dumping device rendering a waste collection vehicle adaptable from a commercial waste collection vehicle to a residential waste collection vehicle is easily attached to a waste collection vehicle. This device includes the provision of a multi-purpose dumping device provides both a commercial device and residential pick-up device. It is also easily operable by the current vehicle structure without substantial modification to the tipping mechanism.

(18) The multi-purpose dumping device is usable with any standard waste collection vehicle or garbage truck. This multi-purpose dumping device is especially suitable for use on a commercial device such as that described in U.S. Pat. No. 5,425,613 to Warren Osborn, incorporated herein by reference. In this manner, the described vehicle can pick up and empty both commercial sized and residential sized waste containers on the same route without returning to its base, while retaining the ability to empty either container and put it back into a desired position.

(19) Basically, the multi-purpose dumping device includes an actuator assembly for handling large waste containers and a cart tipper for handling the smaller, usually residential, wheeled containers. Preferably, the cart tipper is centrally mounted on the rear of a waste collection vehicle in the center of an actuator assembly for handling large waste containers.

(20) In FIG. 1, multi-purpose container dumper 100 is mounted for standard waste collection procedures on truck 102. While resting on ground 104, the actuator assembly 120, as part of the multi-purpose container dumper 100, cooperates with the bang bar assembly 200 to empty a commercial dumpster 400. Cart tipper 500 serves the same purpose for the residential container. Many styles of cart tippers 500 are known. An especially suitable device is sold with the trademark revolution, by Bayne Premium Lift Systems of Greenville, S.C. Other cart tippers can also be used.

(21) Adding FIG. 2 to the consideration, an exploded view of multi-purpose container dumper 100 in general, and actuator assembly 120 in particular, is depicted. Left hook 122 and right hook 124 are mounted above tip bar assembly 130. Each of left hook 122 and right hook 124 are mounted on the shaft 134 of its own actuator 132. Each actuator 132 is covered by an actuator cover 136 clipped, welded, bolted or otherwise secured thereto. Upper cylinder pin 142 secures tip bar lift cylinder 146 to the tip bar assembly 130, while cylinder anchor 148 is secured to flat end 150 of tip bar lift cylinder 146. This assembly is welded to truck 102 in a standard fashion. By the same token, welded base frame assembly 154 is secured to truck 102 (FIG. 1).

(22) More particularly, welded base frame assembly 154 has a bolster 156 as a support bar with a first side plate 158 and a second side plate 160 mounted on either end thereof, by gluing, welding, bolting or securing means or device. Positioned adjacent to first side plate 158 is first light housing 164, while adjacent to second side plate 160 is second light housing 162. Typically, the first light housing 164 and the second light housing 162 are bolted or otherwise secured to the welded base frame assembly. A bolster pin 138 supports the tip bar assembly 130.

(23) Further adding FIG. 3 to the consideration, the structure of bang bar assembly 200 becomes more clear. Bang bar cylinder 202 has a bang bar cylinder anchor 204 secured at one end thereof. A pair of pivot brackets 208 have centrally mounted therebetween a cylinder coupling bracket 210. More specifically, each pivot bracket is mounted at opposing end of the bang bar striker 212, while the cylinder coupling bracket 210 is centrally mounted on the bang bar striker 212 and secured to bang bar cylinder 202.

(24) For clarification of the assembly, FIG. 4 may be considered. Multi-purpose container dumper 100 is mounted on truck 102 to empty either a large waste container such as dumpster 400 or a smaller container such as roll out cart 502. Bang bar assembly 200 provides contact with the lifted dumpster 400 and provides a jarring note to assist with the transfer of material from the dumpster 400 into the truck 102.

(25) Turning now to the consideration of FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9, FIG. 10, and FIG. 11, the empty process and return process for the dumpster 400 is depicted. Multi-purpose container dumper 100 for truck 102 situated on ground 104 has left hook 122 and right hook 124 are positioned on trunion 350 of dumpster 400 in contact position 352. As left hook 122 and right hook 124 make contact with each end of trunion 350, the design thereof positions the trunnion 350 and the dumpster 400 in a proper position.

(26) Left hook 122 and right hook 124 achieve contact position 352 (FIG. 5), which leads to lift and align position 356 (FIG. 6). From lift and align position 356, dumpster 400 moves to pull and lift position 358 (FIG. 8), then followed by raise position 360 (FIG. 9). From raise position 360, dumpster 400 moves to dump and bump position 380 (FIG. 10).

(27) Dump and bump position 380 brings dumpster 400 into contact with bang bar assembly 200, as bang bar assembly 200 position of bang bar deployed 300. Bang bar cylinder 202 achieves that position of bang bar deployed 300. Bang bar cylinder anchor 204, pivot bracket 208, and cylinder coupling bracket 210 provide contact for bang bar assembly 200 and bang bar striker 212.

(28) As dumpster 400 is lowered back to ground 104, proper relocation is achieved with a push back action 382 of the tip bar assembly 130. As can be seen (FIG. 11), tip bar assembly 130 contacts dumpster 400 below trunion 350. As left hook 122 and right hook 124 contact trunion 350, and lift or lower dumpster 400, the cooperation of tip bar assembly 130 is useful.

(29) When FIG. 12, FIG. 13, FIG. 14, and FIG. 15 are considered, cart tipper 500 is shown in use on truck 102. While resting on ground 104. Residential trash container or roll out cart 502 achieves a grip position 504 (FIG. 12) shows the initial position of roll out cart 502. As cart tipper 500 elevates roll out cart 502, lift cart position 506 is achieved (FIG. 13). From lift cart position 506, cart lid 504 exposes the contents of roll out cart 502 in the rotate and dump position 508 (FIG. 14). Then the roll out cart 502 can be held in a storage position 510 on truck 102, or returned to the ground 104.

(30) In this fashion, it becomes clear that the multi-purpose container dumper 100 of this invention is suitable for a dumpster 400 or a roll out cart 502. Both of these waste containers can be handled by the same truck 102 in view of the multi-purpose container dumper 100. Such flexibility provides great advantage by greatly improving the efficiency of waste collection.

(31) This applicationtaken as a whole with the abstract, specification, claims, and drawingsprovides sufficient information for a person having ordinary skill in the art to practice the invention disclosed and claimed herein. Any measures necessary to practice this invention are well within the skill of a person having ordinary skill in this art after that person has made a careful study of this disclosure.

(32) Because of this disclosure and solely because of this disclosure, modification of this method and apparatus can become clear to a person having ordinary skill in this particular art. Such modifications are clearly covered by this disclosure.
