Abstract
Abstract An apparatus for forming compressed fuel logs from shredded waste paper impregnated with oil. The apparatus includes an upwardly open receiving chamber within which a charge of partially compressed material is received, the material being directed to the receiving chamber by an upright chute. A lateral compression ram moves the charged material from the receiving chamber to a compression chamber and reduces the width of the charge. The perpendicular compression ram reduces the length of the charge within the compression chamber. The finished log is discharged through a release door in the compression chamber during retraction of the two rams.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
40 words
The apparatus as set out in claim 1 wherein one side wall of said chute is transversely adjustable relative to the other, whereby the interior volume of the chute may be changed dependent upon the density of material received therein.
Claim 2
Dependent Claim
147 words
The apparatus as set out in claim 1 wherein said lateral ram comprises: an upright wall extending the full width and height of said receiving chamber; and a top wall extending outwardly from the upper edge of said upright wall oppositely to the compression chamber, the length of said top wall being such as to close the lower end of the chute when the lateral ram is in its second position; guide means fixed relative to said receiving chamber for guiding said upright wall and top wall along a transverse path parallel to the end walls of the receiving chamber; and a toggle mechanism operatively connected between the upright wall and the framework of said receiving chamber for selectively moving the walls along said guide means relative to said receiving chamber, said toggle mechanism having a straight configuration when the lateral ram is in its second position.
Claim 3
Dependent Claim
39 words
The apparatus as set out in claim 1 wherein the bottom wall of said compression chamber is movable between a position coincident with the bottom wall of the receiving chamber and a position permitting removal of a compressed log.
Claim 4
Dependent Claim
42 words
The apparatus as set out in claim 4 wherein the bottom wall is hinged along one edge of the compression chamber; and cooperating cam and roller means for selectively locating said wall relative to the hinge pivot in response to gravitational forces.
Claim 5
Dependent Claim
133 words
In an apparatus for compressing shredded waste paper impregnated with oil: a vertical hopper comprising an upright chute having a horizontal cross-sectional configuration corresponding to the desired configuration of a charge of shredded waste paper; an open sided enclosure at the lower end of the chute in open communication therewith for receiving a charge of shredded waste paper from within the chute; lateral compression means for shifting a charge of shredded waste paper within the enclosure transversely relative to the chute against a stationary end wall to thereby reduce the width of the charge; perpendicular compression means for reducing the length of the charge while engaged by said lateral compression means; and a movable wall within the enclosure permitting removal of a compressed charge upon release of said lateral and perpendicular compression means.
