Abstract
Abstract Disclosed is a compactor which may be utilized to compact waste material including small wood or bark pieces and chips, paper, and paper cartons and form the material into a useful form such as fireplace logs. The device employs a cylinder which is removable from a base, and a piston, the rod of which extends through a head removable from the top of the cylinder for loading. Special bail port construction provides for setting a baling wire in place in the cylinder, holding it in place during loading and compression, securing the compression material in its compacted condition with the bail, and removing the formed and secured product from the compactor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
132 words
A compactor comprising an elongated cylinder removably secured to a base, at least two bail ports in an upper portion of the wall of said cylinder substantially oppositely, circumferentially disposed therethrough, a cap removably secured to the top of said cylinder, a prime mover secured to said cap, a piston slidable within said cylinder and having a connecting rod sufficiently long to extend a substantial portion of the length of said cylinder and connected to said prime mover, said prime mover being operable to force said piston axially through a portion of said cylinder to compact material therein and being further operable to allow release and axial withdrawal of said piston from its compacting position, and groove means in the bottom of said piston adapted for angular alignment with said bail ports.
Claim 2
Dependent Claim
132 words
A compactor comprising an elongated cylinder removably secured to a base, at least two bail ports in an upper portion of the wall of said cylinder substantially oppositely, circumferentially disposed therethrough, a cap removably secured to the top of said cylinder, a prime mover secured to said cap, a piston slidable within said cylinder and having a connecting rod sufficiently long to extend a substantial portion of the length of said cylinder and connected to said prime mover, said prime mover being operable to force said piston axially through a portion of said cylinder to compact material therein and being further operable to allow release and axial withdrawal of said piston from its compacting position, and groove means in the bottom of said piston adapted for angular alignment with said bail ports.
Claim 3
Dependent Claim
35 words
The compactor of claim 1 wherein said bail ports are in the general form of slots which extend generally axially through the top of the cylinder wall to allow the insertion of preformed, predimensioned bails.
Claim 4
Dependent Claim
19 words
The compactor of claim 1 wherein the edges of said piston contiguous said groove means are recessed radially inwardly.
Claim 5
Dependent Claim
31 words
The compactor of claim 1 wherein bail access apertures are located in lower portions of the cylinder wall at positions of substantial angular alignment with said groove means in said piston.
Claim 6
Dependent Claim
28 words
The compactor of claim 1 wherein said piston is fixed in position on said connecting rod, and said connecting rod is nonrotatable but axially movable through said cap.
Claim 7
Dependent Claim
43 words
The compactor of claim 5 wherein cooperating locking means are provided on said cylinder and said cap adapted to releasably secure said cap to said cylinder with said groove means of said piston in angular alignment with said bail ports in said cylinder.
Claim 8
Dependent Claim
51 words
The compactor of claim 6 wherein cooperating locking means are provided on said cylinder, said cap and said base, for releasably securing said cap and said base to said cylinder with said groove means of said piston in angular alignment with said bail ports and said access apertures in said cylinder.
Claim 9
Dependent Claim
44 words
The compactor of claim 7 wherein said locking means comprises stud and cooperating bayonet slot means whereby selective rotation of the cap relative to the cylinder and of the cylinder relative to the base can lock and release the cap and the cylinder respectively.
Claim 10
Dependent Claim
32 words
The compactor of claim 1 wherein said prime mover comprises a hand levered ratchet jack, the stanchion of which is nonrotatably axially slidable through said cap and is affixed to said piston.
Claim 11
Dependent Claim
61 words
The compactor of claim 9 wherein the hand lever of said jack is provided with a compression pawl which is normally spring urged out of engagement with said stanchion, and is also provided with a hold pawl which is hand movable into and out of engagement with said stanchion to allow easy hand retraction of said piston axially of said cylinder.
