Abstract

Abstract A compactor for compacting and storing waste material comprises a storage box and a detachable, portable packing mechanism so that a single packing mechanism can be used with a number of storage boxes. The storage box has a top opening loading chute, and the packing mechanism is positioned over the opening. The packing mechanism includes a main frame assembly and a subframe assembly which is pivotally mounted within the main frame. The entire subframe assembly is raised to permit the material to be loaded in the chute and then latched in the closed position while a platen of the subframe assembly is driven through the chute by a hydraulic ram to eject and compact the material from the chute into the storage box.

Claim 3
Dependent Claim 26 words
The invention defined in claim 1 wherein the charge chamber means include a top loading chute which extends outwardly from one wall of the storage box.
Claim 4
Dependent Claim 228 words
A compactor for compacting and storing waste material, said compactor comprising, a storage box for storing the compacted material and having charge chamber means for receiving the material to be compacted and stored, a packing mechanism including a platen and power means for driving the platen through the charge chamber means to eject and compact the material from the charge chamber means into the storage box, and connecting means for detachably connecting the packing mechanism to the storage box whereby a single packing mechanism can be used with a number of storage boxes, and wherein the charge chamber means include a top opening for loading the material into the charge chamber means, the packing mechanism includes a main frame assembly and a subframe assembly and the subframe is positionable over said opening to close the opening when the packing mechanism is connected to the storage box by said connecting means, the subframe assembly includes a platen and platen pivot means pivotally connnecting the platen in the subframe, said power means include a ram connected in the subframe assembly for swinging the platen about said pivot and through the charge chamber means, and wherein the compactor includes a subframe pivotal connection between the subframe assembly and the main frame assembly which permits the entire subframe assembly to be swung upwardly about the pivot to open said charge chamber opening.
Claim 5
Dependent Claim 228 words
A compactor for compacting and storing waste material, said compactor comprising, a storage box for storing the compacted material and having charge chamber means for receiving the material to be compacted and stored, a packing mechanism including a platen and power means for driving the platen through the charge chamber means to eject and compact the material from the charge chamber means into the storage box, and connecting means for detachably connecting the packing mechanism to the storage box whereby a single packing mechanism can be used with a number of storage boxes, and wherein the charge chamber means include a top opening for loading the material into the charge chamber means, the packing mechanism includes a main frame assembly and a subframe assembly and the subframe is positionable over said opening to close the opening when the packing mechanism is connected to the storage box by said connecting means, the subframe assembly includes a platen and platen pivot means pivotally connnecting the platen in the subframe, said power means include a ram connected in the subframe assembly for swinging the platen about said pivot and through the charge chamber means, and wherein the compactor includes a subframe pivotal connection between the subframe assembly and the main frame assembly which permits the entire subframe assembly to be swung upwardly about the pivot to open said charge chamber opening.
Claim 6
Dependent Claim 72 words
The invention defined in claim 3 including latching means for latching the subframe assembly to the charge chamber means to hold the subframe assembly in the closed position over said opening during the power stroke of the platen. 5. The invention defined in claim 4 wherein the charge chamber means include a chute and the latching means include a movable hook on the subfreme assembly and a fixed stop on the chute.
Claim 7
Dependent Claim 19 words
The invention defined in claim 4 wherein the latching means include an overcenter link mechanism on the subframe assembly.
Claim 8
Dependent Claim 27 words
The invention defined in claim 6 wherein the overcenter mechanism includes a handle for operating the mechanism and for raising the subframe assembly about said pivotal connection.
Claim 9
Dependent Claim 27 words
The invention defined in claim 3 wherein the ram is a hydraulic ram and the power means include a hydraulic motor mounted on the main frame assembly.
