Abstract
Abstract A transportable body defines a compartment therein containing back-to-back ejector means, each comprising a vertically disposed inner wall section pivotally connected to a horizontally disposed floor section. A normally closed outer wall section is pivotally mounted on each open side of the body and each is connected to a floor section to open upon actuation of a vertically disposed double-acting hydraulic cylinder. The cylinder is interconnected between the body and the inner wall sections to move them upwardly during the ejecting phase of refuse disposal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
An ejector-type refuse container comprising a body including vertically disposed and spaced wall members, at least one normally horizontally disposed floor section positioned at a lower end of said body, first pivot means pivotally mounting a first end of said floor section on a lower end of said body adjacent to an open lateral side thereof, at least one normally vertically disposed inner wall section positioned laterally inwardly of the lateral side of said body, second pivot means pivotally connecting a first, lower end of said inner wall section to a second end of said floor section, and vertically disposed extensible and retractable actuating means having a first end thereof attached to the lower end of said body and a second end thereof pivotally attached to a second, upper end of said inner wall section.
Claim 2
Dependent Claim
135 words
An ejector-type refuse container comprising a body including vertically disposed and spaced wall members, at least one normally horizontally disposed floor section positioned at a lower end of said body, first pivot means pivotally mounting a first end of said floor section on a lower end of said body adjacent to an open lateral side thereof, at least one normally vertically disposed inner wall section positioned laterally inwardly of the lateral side of said body, second pivot means pivotally connecting a first, lower end of said inner wall section to a second end of said floor section, and vertically disposed extensible and retractable actuating means having a first end thereof attached to the lower end of said body and a second end thereof pivotally attached to a second, upper end of said inner wall section.
Claim 3
Dependent Claim
43 words
The invention of claim 1 further comprising a normally vertically disposed outer wall section pivotally mounted on said body for normally closing the open lateral side thereof to define a closed compartment with said wall members and said inner wall and floor sections.
Claim 4
Dependent Claim
66 words
The invention of claim 2 wherein said outer wall section is pivotally mounted on an upper end of said body adjacent to the lateral side thereof and further comprising linkage means pivotally interconnected between said floor and inner wall sections and said outer wall section for automatically moving said outer wall section to open the lateral side of said body upon extension of said actuating means.
Claim 5
Dependent Claim
47 words
The invention of claim 1 wherein the second end of said actuating means is attached to second, upper ends of two of said inner wall sections and wherein one of said floor sections is attached to the first, lower end of each of said inner wall sections.
Claim 6
Dependent Claim
83 words
The invention of claim 4 wherein said body is open on each lateral side thereof and further comprising two normally vertically disposed outer wall sections each pivotally mounted on an upper end of said body for normally closing a respective open lateral side thereof and means operatively connected between each of said floor sections and a respective outer wall section for automatically moving said outer wall sections to open the lateral sides of said body in response to extension of said actuating means.
Claim 7
Dependent Claim
19 words
The invention of claim 5 wherein said actuating means is positioned intermediate, between the lateral sides of said body.
Claim 8
Dependent Claim
31 words
The invention of claim 6 wherein said actuating means comprises a hydraulically actuated cylinder positioned at each longitudinal end of said body adjacent to a respective one of said wall members.
Claim 9
Dependent Claim
31 words
The invention of claim 1 further comprising guide means operatively associated between said body and said actuating means for guiding vertical movements of said actuating means upon extension and retraction thereof.
Claim 10
Dependent Claim
