Definitions

  • a refuse body hasa position controlling member pivotally connected to an upper portion of the tailgate for oscillatory movement,with said controlling member having a lower telescopic section, there being a packer blade pivotally connected to the lower edge of said telescopic section.
  • PATENTEDMIB 8 I912 SHEET 2 [1F 5 I IIIIIIIII v ATTORNEYS PATENTEDMIB M2 I 3.682.336
  • the tip of the packer blade describes a simple arc during its swinging movement, with the face of the packer blade in effect equal in length to the radius of the arc of the bottom of the hopper.
  • This arrangement limits loading hopper shape to that which conforms to the simple arcuate movement of the blade tip, and therefore it does not permit shaping of the hopper in ways which would increase efiiciency for the receipt of refuse.
  • the blade is supported by the carrier plate, which places a limitation on the distribution of load forces.
  • the present invention provides a novel refuse body loading mechanism in which there is a blade position controlling member pivotally connected to an upper portion of the tailgate for oscillatory movement, said member having a lower telescopic section. Pivots for the packer blade are supported on the tailgate either from the ends of swinging links or in side wall slots.
  • the telescopic section has a connection with the packer blade which is offset from the axis of the before-men tioned packer blade pivots so that the movement of the blade creates a novel downward and inward movement of the blade position controlling member.
  • a general object of the present invention is to provide an improved refuse body loading mechanism which permits a loading hopper shape which has a more efficient refuse receiving shape which can be made deeper below the hopper lip.
  • a further object of the invention is to provide a refuse body as above described wherein the novel blade position controlling member and its telescopic section provides a complete barrier against spillback of refuse in all positions of adjustment. Thus no separate baffle is required.
  • a further object of the invention is to provide an improved arrangement wherein the pivotal connection between the blade and telescopic section is independent of and offset from the pivotal connection between the blade and a special support for the blade.
  • a further object of the invention is to provide in a device as above described an improved arrangement wherein the pivotal connection between the blade and its support on the tailgate is so located that its position is advantageous during the packing stroke to absorb the load forces and thus transmit them to the tailgate frame.
  • a further object of the invention is to provide an improved refuse body loading mechanism in which the pivotal support for the blade with respect to the tailgate is such as to influence the motion of the telescoping platen section of the blade controller. This is accomplished in a way to achieve a motion which acts as an additional packing and holding force upon the refuse being packed in that, as the blade is swung upwardly at the end of the packing stroke, it causes downward and inward movement of the blade position controlling member, which exerts extra pressure on the packed load at this period in the cycle of operation, which position of the platen is maintained to produce a refuse holding effect for a portion of the cycle thereafter.
  • the invention consists of the improved refuse body loading mechanism and all of its parts and combinations, as set forth in the claims, and all equivalents thereof.
  • FIG. 1 is a perspective view looking principally at the rear end portion of a refuse truck,'showing the tailgate equipped with one form of the improved packing mechanism;
  • FIG. 2 is a view partially in perspective, looking principally into the rear of the tailgate, showing the packing mechanism with the blade extended and about to sweep refuse fromv the hopper into the storage compartment of the truck, part of the top of the tailgate being broken away;
  • FIG. 3 is a side elevational view, partially in vertical cross section, with the side of the tailgate removed to show a side view of the packing mechanism, parts of which have been broken away and shown in section, the packer plate-being about to move refuse from the hopper toward the storage compartment, the broken lines showing the packing blade at the end of its swinging stroke;
  • FIG. 4 is a sectional view taken on the line 44 of FIG. 3;
  • FIG. 5 is a partially diagrammatic view showing the parts advanced beyond the broken line position of FIG.
  • FIG. 6 is a diagrammatic view showing the motions of the parts and the quadrangular path of the pivot between the blade and the telescopic platen section;
  • FIG. 7 is a vertical cross-sectional view through the tailgate showing a modified form of the invention.
  • FIG. 8 is a fragmentary rear end view of the modification of FIG. 7;
  • FIG. 9 is a sectional view taken on the line 9-9 of FIG. 7;
  • FIG. 10 is a fragmentary sectional view taken on the line 10-10 of FIG. 7;
  • FIG. 1 1 is a diagrammatic view illustrating the movement of the parts of the form of the invention of FIG. 7.
  • the numeral designates a refuse body with a storage chamber 19, the body having a tailgate 21, the lower portion of which forms a hopper for receiving refuse, the tailgate being pivotally connected to the rear of the storage chamber as at 22 in the usual manner so that it can be swung upwardly on the pivots 22 when it is desired to discharge the load.
  • the hopper has side walls 23, a rear opening 24, and a closed top portion 25.
  • Below the loading opening 24 is a loading lip 27 over which refuse is adapted to be dumped, which lip forms the rear edge of a curved hopper portion 26. Due to the novel features of the loading mechanism, it has been possible to make this bottom hopper portion of more efficient shape for its capacity than has heretofore been practical in this general type of device since it can extend more deeply below the lip 27.
  • a blade position controlling member 29 Pivoted as at 28 near the upper end of the tailgate and on opposite sides thereof is the upper end of a blade position controlling member 29 having side members 31, the member being completely closed by sheet material 30 from its upper to its lower edges and from one side to the other so that it always fonns a barrier against spillback of refuse.
  • the pivotal connection 28 is accomplished by pivoting the upper ends of the side members 31 to the sides of the tailgate.
  • the blade controlling member 29 is mounted for oscillatory movement.
  • the sides 31 of the blade controlling member are in the form of rails as shown in FIG. 4. They are slideably received in side recesses 33 of a lower telescopic platen section 34, the platen section having upwardly projecting side plates 35.
  • bearing shoe slide assemblies 36 engageable with the upper flanges of the rails 31.
  • bearing shoe slide assemblies 36 engageable with the upper flanges of the rails 31.
  • lower bearing shoe slide assemblies as at 37 which are engageable with the lower flanges of the side rails 31.
  • housings 38 for hydraulic cylinders 39 are also supported inwardly of the side plates (see FIG. 4) and parallel thereto, the latter being pivotally connected at their upper ends as at 39' to the upper portion of the telescopic platen section 34 and having piston rods 40 which are extensible from their lower ends.
  • Other hydraulic cylinders 41 having piston rods 41 are pivotally connected as at 42 to the upper end of the tailgate on the'same pivot axis as the pivot 28 for the blade controlling member, and have their lower ends pivotally connected to the lower portion of the telescopic platen as at 32 to cause the telescopic movement of the latter relative to the oscillatory blade controlling member 29.
  • a packer blade 44 has upstanding triangular end wings 45. The inner end of each wing has two extension cars as shown in FIG. 5.
  • One set of ears 46 is pivotally connected as at 47 to the lower end of the telescopic platen 34.
  • the other set of ears 48 is pivotally connected as at 49 to the ends of the piston rods 40 of the cylinders 39.
  • the packer blade is supported in a novel manner from the tailgate for pivotal movement and, in the form of the invention of FIGS. 1-6, is pivoted at 50 at the lower ends of swinging links 51.
  • the upper ends of the links 51 are pivotally connected as at 52 to extension brackets 53 on the sides of the tailgate.
  • FIG. 5 this illustrates the completion of a packing cycle after the refuse in the hopper has been delivered and packed into the storage chamber of the body.
  • the rams 40 of the cylinders 39 are extended and the rams 41' of the cylinders 41 are retracted. Refuse may now be dumped into the bottom hopper portion 26 of the tailgate.
  • the packer blade may be cycled.
  • First the hydraulic control valves are operated to cause retraction of the rams 40 of the cylinders 39 to cause swinging of the packer blade around the pivots 47 from the full line position of FIG.
  • the hydraulic rams 40 of the cylinders 39 are extended to act on the pivot points 49 of the blade and cause swinging movement of the blade in a downward and inward direction.
  • the pivot points 47 move upwardly and rearwardly along the path (c) of FIG. 6 in a direction to change the relationship between the pivot points and the bottom of the hopper.
  • the bottom of the hopper is not shaped on a simple arc of a circle. Instead it has a more or less complicated shape which increases its depth and gives it a more efiicient shape.
  • the pivots 150 for the swinging movement of the blade are not supported on the end of links. Instead these pivots are connected with the rollers 154 which ride in the side tracks 155 in the sides of the tailgate.
  • the rams 140 connected with the cylinders 139 are retracted to cause swinging of the packer blade around the pivots 147 of FIG. 11 to a position corresponding to the broken line position of FIG. 5.
  • the pivots 147 between the telescopic platen and the wings 146 of the packer blade move downwardly through the path (a') of FIG. 11.
  • the rams connected with the cylinders 141 are extended to move the packer blade along the path (b') of FIG. 11, carrying the packer blade to the position of FIG. 3.
  • the packer blade is swung in a downward direction around the pivots 147.
  • the pivot points 147 will move through the path (c') of FIG. 11, thus changing the position of the pivot points with respect to the hopper bottom. As before mentioned, this makes it possible to have a hopper bottom of a more advantageous shape.
  • the inward movement of the blade may be stopped short of the position of FIG. 5 or at the opposite end of its travel and then swung upwardly or downwardly.
  • Such short cycle is useful when portable containers are being used to dump refuse into the hopper, as it makes it possible to speed up the operation by getting the refuse out of the way quickly while it is being dumped in.
  • a blade position-controlling member extending transversely of the tailgate and pivoted at its upper end to the upper portion of the tailgate for oscillatory movement, said blade-controlling member having a platen section telescopically associated therewith, a packer blade having a pivotal connection with a lower portion of said platen section, a shiftable pivotal support between the tailgate and blade pivotally supporting the blade above the hopper and also positioned to maintain the blade-controlling member in a generally downwardly and rearwardly inclined position, said pivotal support being in a location on the blade which is independent of and offset from the pivotal connection between the blade and platen section, power means for causing telescopic movement of the platen section, and power means between the platen section and blade for causing swinging movement of the latter whereby the blade may be cycled to move refuse from the hopper
  • a refuse vehicle as claimed in claim 1 in which the power means for. causing telescopic movement of the platen section includes fluid pressure-operated cylinder and ram means, and in which the power means for causing swinging movement of the blade includes fluid pressure-operated cylinder and ram means pivotally connected at one end to the telescopic platen section and at the other end to the blade.
  • a refuse vehicle as claimed in claim 1 in which the shiftable pivotal support between the tailgate and blade comprises links pivotally connected at their upper ends to the tailgate above the blade and pivotally connected at their lower ends to the blade.
