Compactor with fixed compaction chamber and movable plate member

Claim 2

A compactor comprising: a. a compactor housing, b. means defining a fixed compactor chamber within said housing, c. a deformable container received within said chamber and movable between a compacting position within said chamber and a noncompacting position displaced from said compacting position, d. a ram mounted within said housing for reciprocating movement into and out of said container when said container is positioned in said compacting position, e. said ram thereby being adapted to compact material deposited in said container causing bulging of said container into engagement with opposed portions of said chamber, f. a movable plate member positioned between said container and said chamber for relieving pressure between said container and said opposed portions of said fixed chamber, g. tab means on one of said plate members and said chamber and projecting therebetween, h. means defining openings in the other of said plate member and said chamber disposed to receive said tab means upon shifting movement of said plate member, and i. means for shifting said plate member between positions wherein said tab means is received in said opening means and displaced therefrom, thereby moving said plate member alternately between positions toward and away from said chamber and said container to facilitate displacement of said container from said compacting position to said noncompacting position.

Claim 3

The compactor of claim 1 further comprising: a. inclined tabs extending angularly outwardly from adjacent said openings and engageable by said tab means upon shifting movement of said plate member.

Claim 4

A compactor comprising: a. a compactor housing, b. means defining a fixed compactor chamber within said housing, c. a deformable container received within said chamber and movable between a compacting position within said chamber and a noncompacting position displaced from said compacting position, d. a ram mounted within said housing for reciprocating movement into and out of said container when said container is positioned in said compacting position, e. said ram thereby being adapted to compact material deposited in said container causing bulging of said container into engagement with opposed portions of said chamber, f. a plate member interposed between a wall of said container and an opposed wall of said chamber, g. first tabs projecting outwardly from said plate member away from said wall of said container toward said wall of said chamber, h. a plurality of openings formed through said wall of said chamber corresponding to said first tabs projecting from said plate member, whereby said first tabs are receivable in said openings, i. inclined tabs associated with each of said openings and extending angularly outwardly away from said wall of said chamber, and j. handle means adapted to shift said plate member generally parallel to said walls of said container and said chamber to allow said first tabs to project through said openings in engagement with said inclined tabs, thereby relieving pressure between said container and said chamber and facilitating displacement of said container from said compacting position to said non-compacting position.

Claim 5

A compactor comprising: a. a compactor housing, b. means defining a fixed compactor chamber within said housing, c. a deformable container received within said chamber and movable between a compacting position within said chamber and a noncompacting position displaced from said compacting position, d. a ram mounted within said housing for reciprocating movement into and out of said container when said container is positioned in said compacting position, e. said ram thereby being adapted to compact material deposited in said container causing bulging of said container into engagement with opposed portions of said chamber, f. a plate member interposed between a wall of said container and an opposed wall of said chamber, g. first tabs projecting outwardly from said plate member away from said wall of said container toward said wall of said chamber, h. a plurality of openings formed through said wall of said chamber corresponding to said first tabs projecting from said plate member, whereby said first tabs are receivable in said openings, i. inclined tabs associated with each of said openings and extending angularly outwardly away from said wall of said chamber, and j. handle means adapted to shift said plate member generally parallel to said walls of said container and said chamber to allow said first tabs to project through said openings in engagement with said inclined tabs, thereby relieving pressure between said container and said chamber and facilitating displacement of said container from said compacting position to said non-compacting position.
