Definitions
- the present invention relates to a refuse loader and packing system and, more particularly, to mechanisms particularly adapted to receive and load trash from presently used types of refuse containers.
- the present invention has been derived to present an alternate method for the servicing of trash collection routes and for the periodic and scheduled dumping of these same refuse containers that have been sold and used in connection with the previous systems.
- the basic object of the present invention is to provide a more efiicient trash collection system through the elimination of excessive travel time between dump sites and points of collection.
- a further object of the invention is to provision of van walls of outwardly expendable construction to receive refuse container raised to the dumping position.
- FIG. 1 is a side elevation in partial section showing a refuse container raised to a support engaging position
- FIG. 2 is a side elevation illustrating the dumping position for such refuse container and further showing in dotted line alternate position an intermediate hoisting position,
- FIG. 3 is a partial side elevation showing a boom hoisting mechanism and further illustrating alternate positions of such mechanism in dotted outline representation
- FIG. 4 is a rear elevation illustrating alternate movement positions for the van sidewalls
- FIG. Si is a front, elevation showing alternate movement positions for the van sidewalls
- FIG. 6 is a front view in partial section showing the alternate lateral positions for the hoist mechanisms
- FIG. 7 is a side elevation with a sidewall removed showing an alternate container dumping position.
- the present invention provides, a system and mechanisms whereby the collected trash materials in a plurality of bottom dump type refuse containers may be hoisted and dumped into a single van carrier for efficient transport to dump sites.
- the mechanism is intended for use with presently available refuse containers.
- the sizing of such presently used refuse containers requires the incorporation of further mechanisms for the lateral and cooperative expansion of hoist arms, pivots and van sidewalls so that the containers may be raised to position above a top receptor opening in the van carrier to be later lowered into the van carrier to dump the collected trash without interference from the outwardly moved van sidewalls.
- mechanical systems are provided for raising the refuse containers to engage position and for raising the boom and container to the dumping position while at the same time cooperatively extending the boom arms, the van sidewalls and other inter-related elements laterally away from positions of interference.
- FIG- URES 1 and 2 in general indicate the overall assembly and cooperative working of the elements of the invention.
- a van carrier type of body 11 is mounted on a truck frame 12.
- the van carrier is of near conventional type insofar as it provides a top receptor opening 13 into which refuse materials may be dumped to be moved backwardly into the full enclosure of the van 11 by means of a packer unit (not shown) which can be moved from a forward position against the front end wall 16 toward the opposite end of the van carrier.
- the structure as here described is similar to that used in various types of top loading refuse or rubbish removal vans now in general use.
- the truck 12 further provides. support for boom hoisting apparatus 19, which includes the boom arms 21 disposed on opposite sides of the truck frame 12 for pivoting movement on lower trunnions 22.
- the boom arms 21 are raised and lowered about the trunnions 22 by extension and retraction of the cable 23, which in the present confiiguration is powered by an expanding hydraulic cylinder and cable system 24, more fully shown in FIGURE 3.
- a boom stick extension 26 is mounted on the upper end of the boom arms 21 for rotational movement about an upper split pivot 27.
- the angular movements of the stick extension 26 with respect to the boom arms 21 is regulated and controlled by the extension and retraction of a double-acting hydraulic cylinder 28 which is mounted on a boom support cross member 29 extending laterally from one box support 31 on a first boom arm 21 to the opposite box support 31 on the other boom arm 21.
- the boom arms 21 are lowered to a forwardly extended posi tion, as shown in FIGURE 1.
- the stick extension 26 is rotated to the position shown in FIGURE 1 so that the lower end 32 of the stick extension 26 may be brought into engagement with an upwardly extending support 33 on the truck frame.
- a cable 34 which is unwound from the winch 36, is engaged with the dump pins 37 of a refuse container 38.
- FIGURE 2 The relative position of the described elements when the refuse container 38 is being dumped is shown in full view in FIGURE 2. An alternate intermediate position for such elements is likewise shown in this figure.
- the boom arms 21 are pulled to a full backward position by the cable 23, the stick extension 26 is simultaneously pivoted about split pivots 27 to the position illustrated.
- This desirable movement pattern is accomplished through extension of the double-acting hydraulic cylinder 28.
- the described movement of the boom arms 21 and of the stick extension 26 can be accomplished without further actuation of the dump winch 36, since the cable 34 is reeved over pulleys 43 and 44, which rotate about centers common to the lower trunnion 22 and the upper split pivots 27, respectively, before engaging the dump pins 37.
- the winch 36 is rotated in reverse direction to extend the length of the cable 34.
- This extension of the cable 34 allows the dump pins 37 to move downwardly thereby opening the dump bottom 42 about the outer hinge 46 on the refuse container 38.
- This lowering of the dump bottom 42 necessarily allows all of the collected trash and rubbish to be dumped out of the refuse container 38 and into the forward receptor or packer section of the van carrier 11.
- the winch 36 will be actuated to close the dump bottom 42.
- a buffer cylinder 47 acting against the base of boom arms 21 will be extended to move the boom arms past their over-center dumping position, and subsequently the boom structure will be lowered to the position as shown in FIGURE 1 by extension of the cable 23.
- the refuse container may be lowered to its position of usual placement on the ground by the further actuation of winch 36 to disengage dump hook 41 and to lower the refuse container 38 along the stick extension 26 and the frame support 33 to the ground.
- the described operation of the hoisting and dumping apparatus represents a material part of the present invention; however, it is found that further refinements are necessary for the satisfaction of the objectives of this invention, as previously set forth.
- the major complication arises from the fact that it is desirable to adapt the present system to service various types of refuse containers which are already in use.
- On some present containers in widespread use the outside to outside measurements of the dump pins 37 is approximately 91 inches.
- the standard overall width limitation for vehicles that are to be used on streets and roadways is 8 feet, or 96 inches. With these combined limitations and with the further limitations in the structural strength of conventionally used materials, it is difficult to provide boom arms which will operate outside van sidewalls which must themselves internally receive a dump pin structure 91 inches in width.
- the present invention provides for the reciprocal and lateral extension of several of the described operative elements during periods when the hoisting and dumping operations are being carried out.
- the system further provides for the inward retraction of all such elements when the vehicle is to be moved over streets and roadways between collection points or to the major dump sites.
- the alternate lateral positioning features of this embodiment of the invention are in general shown in FIGURES 4, 5 and 6.
- a study of these figures will show that the satisfactory operation of the system requires the provision of boom elements that are outwardly extensible and van sidewalls in the packer-receptor section of the van carrier that are likewise outwardly movable.
- the features of the boom mounting and lateral extension mechanisms are shown in FIGURE 6, while front and rear elevations of the movable van sidewalls are shown in FIGURES 5 and 4, respectively.
- FIGURE 6 it will be seen that the trunnion shafts 22, which are integrally secured to the boom arms 21, are engaged through truck frame mounted sleeve bearings 48 for reciprocal and rotational movement therein.
- the rotational movement of the arms will be energized by the functions of the cable system 24 and/ or the buffer cylinder 47.
- the reciprocal in and out movement of the trunnions as necessary to effect the lateral extension of the boom arms is regulated by a rocker arm linkage 49.
- This linkage includes connecting links 51 and 52 joined to the trunnion shafts 22, a centrally disposed crank arm 53 and a double-acting hydraulic actuating cylinder 54 having a piston 56 engaged with the crank arm 53 to forcibly move the trunnion shafts 22 inwardly and outwardly as required.
- a similar arrangement, inclusive of link arms 61 and 62 is provided adjacent the top support cross member 29.
- the stroke of the double-acting hydraulic cylinders 54 and 64 and the length of the associated crank arms 53 and 63 are comparable so that the boom arms will be extended equal distances away from the truck supporting frame.
- the support cross member 29 provides for the telescoping cooperative movement of external support elements 67 and internal slide tubes 68 in order to provide a relatively strong supporting structure whether the elements are in their extended or retracted relations.
- the members 67 and 68 are of square tubular cross-section in order to resist wrenching forces that might be exerted against the separate boom arms 21 by nonconcentric loading of the boom or refuse containers hoisted thereby.
- the upper split pivots 27 are adapted to reciprocate within a hollow tubing structure 71, which is a part of and which supports the boom stick extension 26. With this arrangement hydraulic cylinder 28 can act against the pin 72 mounted on the upper extension of stick 26 to rotate the stick extension 26 about the split pivots 27. Since the total lateral extension of the boom arms required is relatively limited, a strong and serviceable structure is provided by the mechanical elements illustrated and described.
- this desirable result is obtained through the provision of outwardly movable sidewalls in the receptor section of the van carrier.
- the movable sidewalls 81 and 82 are hinged to the bottom walls 83 and 84' of the van carrier 11 by hinge members 85 and 86. Normally the walls 81 and 82 will be carried in position vertically above the bottom walls 83 and 84; however, when it is desired to move a refuse container 38 into the dumping position, as shown in FIG- URE 2, front and rear hydraulic cylinders 93 and 94 may be actuated to extend the push rods 91 as necessary to pivotally move the sidewalls 81 and 82 out of positions of interference with the bottom dump door 42 and/or dump pins 37.
- the cylinders 93 and 94 will each be positioned outside of the interior of the receptor section to avoid contamination with trash materials.
- the present embodiment of the invention provides a system whereby present refuse containers with only slight modifications may be more efiiciently serviced by units coming within present governmental size and weight limitations.
- the mechanisms shown and illustrated make it possible to collect the trash from many refuse containers into a single van carrier before it is necessary to take the accumulated trash materials to a dump site.
- the present system and mechanism makes the further utilization of such equipment efficient and economically advantageous.
- a closure top 30 for the receptor opening of the carrier.
- the materials received in the van may be prevented from blowing out of such van when the top 30 is closed.
- the position of the top 30 is governed by the positioning of the hoist arms 21. As the hoist arms 21 are raised, they come into position of interference with extensions 35 on the free end of the top 30. Further upward and rearward movement of the hoist arms causes the top to be pivoted about its rear pivot hinge to an out of the way position, as illustrated in FIGURE 2. After the refuse materials have been discharged into the van carrier, the top may thereafter be moved to its normally closed position.
- Apparatus for handling refuse containers and for receiving and dumping materials collected therein comprising a frame support, a van carrier on said frame providing an enclosure adapted to receive refuse materials, said van carrier further providing a receptor opening for the introduction of said refuse containers and materials, lower pivot mounts on said support, hoist arms on said pivot mounts adapted for pivoting and reciprocal movement with respect to said mounts, means for connecting refuse containers to said hoist arms, means for forcibly rotating said hoist arms with respect to said pivot mounts to raise and lower said arms and the refuse containers supported thereby, means for moving said hoist arms reciprocally along said pivot mounts to provide necessary and otherwise inadequate clearance between said hoist arms and the sidewalls of said van carrier, and means for dumping said containers.
