It will be appreciated that upon supplying fluid under pressure to the front or rear ends of the cylinders 47a and 48a, the pistons or rams 47b and 48b will be extended or retracted to pivot the panel assembly 46 relative to the carrier assembly 43. i
- the control system illustrated in FIG. is operable to actuate the carrier cylinder and piston assemblies 44 and 45 and the panel cylinder and piston assemblies 47 and 48 to cycle the transferring and compacting mechanism 24 within the receiving hopper, to lift the receiving hopper for ejecting refuse compacted in the storage body, and ejecting the refuse from the storage body.
- the system includes a fluid reservoir 85 provided with a filter 86, a pump 87, a selector valve 88, a cylinder control valve 89, a pilot valve 90, a sequence valve 91, and interconnecting fluid lines which will be described in connection with the operation of the system.
- the selector valve 88 and cylinder control valve 89 are spooltype valves which can be shifted axially to divert fluid under pressure to various components of the system as will be described.
- the pilot valve 90 generally is a pressure sensitive type of valve which is operable to shift the spools of the cylinder control valve 89 also as will be described.
- the pump 87 in the operation of the control system to cycle the refuse transferring and compacting mechanism 24, when the carriage and panel assemblies are in the position as illustrated in FIG. 9, the pump 87 is operating and the spools S,, S and S of cylinder control valve 89 are pushed inwardly to begin the cycle, the pump 87 supplies fluid under pressure through line 92, selector valve 88 and line 93 to the cylinder control valve 89, from where the fluid flows simultaneously from a port 94 and through fluid lines 95 and 96 to the lower ends of cylinders 47a and 48a, and from a port 97 and through a fluid line 98 to the sequence valve 91.
- the sequence valve 91 will permit a predetermined small amount of fluid to flow through fluid line 99, 100 and 101 to the upper ends of cylinders 44a and 45a to cause the rods 44b and 45b to begin to retract thus causing the carriage assembly 46 to begin drifting downwardly from position A to position B, and the piston rods 47b and 48b to retract thus causing the panel assembly to pivot upwardly from the position illustrated in solid lines in FIG. 9 to the position designated by reference numeral 102.
- the fluid pressure in line 98 will increase to a predetermined amount sufficient to open the sequence valve 91 fully thus allowing fluid under increased pressure to continue to retract the piston rods 44! and 45b.
- the retraction of piston rods 44b and 45b will operate to move the carriage assembly downwardly and position the panel assembly in a position designated by reference numeral 103 in FIG. 9.
- the pressure in fluid line 100 will increase to a predetermined amount sufficient to actuate a cartridge P in the pilot valve 90 which functions to supply fluid under pressure through a fluid line 104 to shift the spool S outwardly thus stopping the flow of fluid to the lower ends of the cylinders 47a and 48a, and providing a supply fluid under pressure from valve port 94a, through fluid lines 105 and 106 to the upper ends of cylinders 47a and 48a to extend the piston rods 47b and 48b and pivot the panel assembly downwardly from the position designated by reference numeral 103 to the position designated by reference numeral 107 in FIG. 9.
- valve port 97 The shifting of spool S outwardly will stop the flow of fluid through valve port 97 and cause fluid under pressure to be applied through valve port 97a and fluid lines 108 and 109 to the lower ends of cylinders 44a and 45a to extend piston rods 44b and 45b.
- the extension of piston rods 44b and 45b will have the effect of causing the carriage assembly to be moved upwardly to its uppermost position thus moving the panel assembly from the position 107 to its original starting position designated by the reference numeral 110 in FIG. 9.
- Fluid may be drained from the system by means of a fluid line 113 interconnecting the sequence valve 91'and the fluid reservoir 85, a fluid line 114 interconnecting the chambers of the spools S, and S of the cylinder control valve, and the fluid reservoir 85, and a fluid line 115 interconnecting the chamber of the spool S of the cylinder 'control valve 89 and drain line 114. Fluid from the reservoir 85 is supplied through the filter 86 and the fluid line 116 connected to the inlet side of the pump 87.
- the panel assembly When the panel assembly reaches the position designated by numeral 107, the panel assembly remains locked in position relative to the carriage assembly and the carriage assembly moves upwardly to correspondingly move the panel assembly from the position designated by the numeral 107 to its original position designated by the reference numeral 110. As the panel assembly moves from the position 107 to 110 the crushed surface is transferred from the receiving hopper through the restrictive opening 38 into the interior of the storage body where it is compacted against the ejector panel. The procedure as described is repeated until the storage body is filled with compacted refuse.
- the bottom plate member of the panel assembly is subjected to bending stresses about the pivotal connection thereof with the carriage assembly which effectively are resisted by the novel construction of the entire panel assembly including the construction of the components 72 through 78.
- the construction further permits the use of a lighter gauge metal thus providing an increased strength-weight ratio for the panel assembly.
- the refuse within the body may be retained in the compacted position by the panel assembly while the vehicle is driven to a refuse dump site or a municipal incinerator plant where the refuse may be unloaded.
- the unloading of the refuse merely involves operating the pump 87 and actuating a second control lever on the exterior of the receiving hopper to move the spool S of selector valve 88 inwardly.
- Such action causes fluid under pressure to flow through fluid line 92, selector valve 88 and fluid lines 116 and 117 to the ends of cylinders 118 and 119 to extend the piston rods 118a and 119:: thereof/
- the piston and cylinder assemblies 118 and 118a, and 119 and 119a are mounted on the opposite sides of the apparatus and interconnect the refuse hopper and the refuse storage body so that when the piston rods 118a and 119a are extended it will cause the receiving hopper with the mechanism 24 mounted therein to be pivoted upwardly to an elevated position thus exposing the rear opening of the storage body.
- the refuse in the storage body then may be ejected by actuating a third control lever to move the spool S of selector valve 88 inwardly, thus causing fluid under pressure to be supplied through fluid line 92, selector valve 88 and fluid line 120 to the rear end of a cylinder 121 disposed within the storage body.
- the third control lever again is operated to move spool S of selector valve '88 outwardly thus supplying fluid under pressure to the front end of cylinder 121 to retract the telescopic piston rod 122 and move the ejector panel forwardly in the storage body.
- the second control lever also is actuated to move spool S outwardly thus permitting the fluid in the cylinders 118 and 119 to drain and the piston rods 118a and 119a to retract and permit the refuse hopper to pivot downwardly into its normal operating position on the rearward end of the storage body.
- the refuse hopper is then locked to the storage body and the apparatus is in condition to resume its refuse collection routine as previously described.
