Abstract
Abstract A waste baling machine having a baling or compression chamber of generally parallelopiped configuration is provided with a charging passage leading thereto with the head of a charging ram reciprocable in the passage and normally forming, in one position, a wall of the chamber. A discharge passage leads from the chamber at right angles to the charging passage and the head of a discharge ram, which when retracted forms a wall of the chamber, is advancable through the chamber and the discharge passage to eject waste material compressed in the chamber by the charging ram, i.e. a bale. If the bale is oversize and protrudes back into the charging passage, a portion of the wall of the discharge passage which forms a part of the charging passage is moved to enlarge the discharge passage sufficiently to permit ejection of the oversize bale.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
181 words
In a waste baling machine provided with a compression chamber of generally parallelopiped configuration having three fixed walls, a charging passage leading to and having an exit end at said chamber with a charging ram head reciprocable therein and defining in one position, a fourth chamber wall, a discharge passage defined by two pairs of opposed walls leading from said chamber at right angles to said charging passage, and an ejection ram head advanceable through said chamber and said discharge passage and defining in a retracted position a fifth chamber wall, the improvement comprising: the discharge passage wall adjacent the exit end of said charging passage is divided into two sections, one inner and one outer, parallel to the plane of said discharge passage wall, said outer section being fixed and said inner section normally defining a part of said charging passage and being mounted for movement to enlarge said discharge passage throughout its length to permit ejection therethrough of an oversize charge of waste material in said chamber having a portion of said charge protruding back into said charging passage.
Claim 2
Dependent Claim
181 words

Claim 3
Dependent Claim
35 words
The machine defined in claim 1 in which the inner wall section is mounted for linear movement and including motor means connected thereto for moving the same between its normal position and a passage-enlarging position.
Claim 4
Dependent Claim
29 words
The machine defined in claim 2 including fixed guide means for the inner wall section to prevent movement thereof in directions parallel to movement of the ejection ram head.
Claim 5
Dependent Claim
12 words
The machine defined in claim 3 in which the passages extend horizontally.
