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: 9
Claim 1
Independent Claim
241 words
In a refuse collecting vehicle having an elongated body with a body floor, opposed side walls, an open rear end and a hopper like depression in the rear portion of the floor; a. a packer wall horizontally pivotally mounted between said side walls on a pivotal axis forward of said depression, said packer wall comprising: 1. a solid wall portion traversing the space between said side walls, and 2. a scraper blade portion slidably mounted on the rear end of said wall portion and radially movable relative to said packer wall pivotal axis; b. a first power means for pivoting said packer wall between: 1. a packing position wherein said wall portion is completely disposed within said body and approaching a vertical position, and 2. an unloading position wherein said wall portion and scraper blade portion are moved upwardly out of the path of refuse being unloaded out of said body; c. a second power means for radially shifting said scraper blade portion to cause the free edge of said scraper blade portion to sweep forwardly along the floor of said hopper depression as said packer wall moves to said packing position and d. a separate floor member defining the rearward inclined wall of said hopper depression, and means mounting said separate floor member for pivotal movement relative to said body, whereby said separate floor member may be pivoted downward to a non-obstructing position relative to rearward discharge of accumulated refuse.
Claim 2
Dependent Claim

In a refuse collecting vehicle having an elongated body with a body floor, opposed side walls, an open rear end and a hopper like depression in the rear portion of the floor; a. a packer wall horizontally pivotally mounted between said side walls on a pivotal axis forward of said depression, said packer wall comprising: 1. a solid wall portion traversing the space between said side walls, and 2. a scraper blade portion slidably mounted on the rear end of said wall portion and radially movable relative to said packer wall pivotal axis; b. a first power means for pivoting said packer wall between: 1. a packing position wherein said wall portion is completely disposed within said body and approaching a vertical position, and 2. an unloading position wherein said wall portion and scraper blade portion are moved upwardly out of the path of refuse being unloaded out of said body; c. a second power means for radially shifting said scraper blade portion to cause the free edge of said scraper blade portion to sweep forwardly along the floor of said hopper depression as said packer wall moves to said packing position and d. a separate floor member defining the rearward inclined wall of said hopper depression, and means mounting said separate floor member for pivotal movement relative to said body, whereby said separate floor member may be pivoted downward to a non-obstructing position relative to rearward discharge of accumulated refuse.
Claim 3
Dependent Claim
195 words
In a rear loading refuse vehicle having a generally flat body floor, spaced side walls and an open rear end, the improvement comprising, a. a depressed hopper at the rear of said body floor for receiving refuse, said hopper having a bottom consisting of an upwardly inclined front portion and an upwardly inclined rear portion, b. means mounting said rear portion of said hopper bottom for movement between an upper position in which it defines the back of said hopper and a non-obstructing position opening said hopper rearwardly for discharge of refuse therefrom and from said body, and c. a packer blade having a lower edge and that is mounteD in said body for moving refuse out of said hopper forwardly into said body, said lower edge being movable along a lower path including movement of said lower edge forwardly down into and through said hopper and an upper path extending rearwardly over refuse in said hopper at such a level thereabove that the open space between said lower edge and the rear edge of said rear portion of said hopper when in non-obstructing position is generally equal to the open end of said body.
Claim 4
Dependent Claim
195 words
In a rear loading refuse vehicle having a generally flat body floor, spaced side walls and an open rear end, the improvement comprising, a. a depressed hopper at the rear of said body floor for receiving refuse, said hopper having a bottom consisting of an upwardly inclined front portion and an upwardly inclined rear portion, b. means mounting said rear portion of said hopper bottom for movement between an upper position in which it defines the back of said hopper and a non-obstructing position opening said hopper rearwardly for discharge of refuse therefrom and from said body, and c. a packer blade having a lower edge and that is mounteD in said body for moving refuse out of said hopper forwardly into said body, said lower edge being movable along a lower path including movement of said lower edge forwardly down into and through said hopper and an upper path extending rearwardly over refuse in said hopper at such a level thereabove that the open space between said lower edge and the rear edge of said rear portion of said hopper when in non-obstructing position is generally equal to the open end of said body.
Claim 5
Dependent Claim
116 words
an unloading position wherein said wall portion and scraper blade portion are moved upwardly out of the path of refuse being unloaded out of said body; c. a second power means for radially shifting said scraper blade portion to cause the free edge of said scraper blade portion to sweep forwardly along the floor of said hopper depression as said packer wall moves to said packing position and d. a separate floor member defining the rearward inclined wall of said hopper depression, and means mounting said separate floor member for pivotal movement relative to said body, whereby said separate floor member may be pivoted downward to a non-obstructing position relative to rearward discharge of accumulated refuse.
Claim 6
Dependent Claim
116 words
an unloading position wherein said wall portion and scraper blade portion are moved upwardly out of the path of refuse being unloaded out of said body; c. a second power means for radially shifting said scraper blade portion to cause the free edge of said scraper blade portion to sweep forwardly along the floor of said hopper depression as said packer wall moves to said packing position and d. a separate floor member defining the rearward inclined wall of said hopper depression, and means mounting said separate floor member for pivotal movement relative to said body, whereby said separate floor member may be pivoted downward to a non-obstructing position relative to rearward discharge of accumulated refuse.
Claim 7
Dependent Claim
