Abstract
Abstract This invention relates to a rear end loader type of refuse collecting vehicle. There is no tailgate and the loading hopper, rather than being in the tailgate, is in the rear of the vehicle body. A packing blade moves refuse from the hopper into the forward portion of the body and in one embodiment may be reversed to sweep refuse from the hopper to a point exterior of the vehicle. A longitudinally movable ejector panel is mounted transversely of the body. During the discharging of refuse from the open rear end of the body the packer blade is in an elevated position and the refuse is discharged by the ejector panel between the elevated packer blade and the hopper. In some embodiments an auxiliary floor is provided in the hopper.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
253 words
In a refuse collecting vehicle having an elongated body with an open rear end, said body including opposed side walls, a top, a body floor and a hopper extending below the level of said body floor adjacent said rear end, said hopper being an integral part of said body and inseparable therefrom, an ejector plate in said body and extending substantially from said top to said floor and across between said side walls for discharging refuse through said open rear end, a packer blade extending transversely across said body and having an upper end and a lower end that is adapted to be moved along the bottom of said hopper for sweeping refuse from said hopper into said body, means for moving said packer blade between a lower packing path with said lower end extending into said hopper and an upper return path with said packer blade and said lower end elevated to a level above the top of said ejector plate a distance such that refuse may be discharged from said body by said ejector plate through the open space between said body floor and said lower end, means for moving said packer blade generally forwardly along said lower packing path for sweeping refuse from said hopper into said body and generally backwardly along said upper return path for moving said packer blade rearwardly over refuse in said hopper, and power means for moving said ejector plate through said body to said open end for discharging refuse therefrom through such open space.
Claim 2
Dependent Claim
253 words
In a refuse collecting vehicle having an elongated body with an open rear end, said body including opposed side walls, a top, a body floor and a hopper extending below the level of said body floor adjacent said rear end, said hopper being an integral part of said body and inseparable therefrom, an ejector plate in said body and extending substantially from said top to said floor and across between said side walls for discharging refuse through said open rear end, a packer blade extending transversely across said body and having an upper end and a lower end that is adapted to be moved along the bottom of said hopper for sweeping refuse from said hopper into said body, means for moving said packer blade between a lower packing path with said lower end extending into said hopper and an upper return path with said packer blade and said lower end elevated to a level above the top of said ejector plate a distance such that refuse may be discharged from said body by said ejector plate through the open space between said body floor and said lower end, means for moving said packer blade generally forwardly along said lower packing path for sweeping refuse from said hopper into said body and generally backwardly along said upper return path for moving said packer blade rearwardly over refuse in said hopper, and power means for moving said ejector plate through said body to said open end for discharging refuse therefrom through such open space.
Claim 3
Dependent Claim
39 words
A refuse collecting vehicle according to claim 1, and control means for reversing the travel of said packer blade along said packing path whereby said packer blade is effective to remove refuse from said hopper during such reverse travel.
Claim 4
Dependent Claim
30 words
A refuse collecting vehicle according to claim 1, including an auxiliary floor positioned within said hopper, said auxiliary floor being movable between a lower position and an upper discharge position.
Claim 5
Dependent Claim
25 words
A refuse collecting vehicle according to claim 3, including cylindEr means for moving said auxiliary floor between such lower position and such upper discharge position.
Claim 6
Dependent Claim
33 words
A refuse collecting vehicle according to claim 4, wherein said ejector panel moves adjacent the upper surface of said auxiliary floor when discharging refuse from such open rear end of said elongated body.
Claim 7
Dependent Claim
75 words
A refuse collecting vehicle according to claim 1 in which said means for moving said packer blade between said lower packing path and said upper return path includes means for moving said packer blade to and from an intermediate return path with said lower end of said packer blade at a level above refuse in said hopper and lower than the level of the top of said ejector plate when in said intermediate return path.
Claim 8
Dependent Claim
47 words
A refuse collecting vehicle according to claim 1 including an auxiliary floor pivotally mounted within said hopper on a pivot line adjacent the front side of said hopper, and means for moving said auxiliary floor between a lower position and an upper discharge position spanning said hopper.
