Abstract
Abstract Waste compacting apparatus comprising a hopper; a compaction tunnel communicating with the hopper and providing an outlet for waste deposited therein; a packer located and reciprocable through successive forward and return strokes to advance waste from the hopper into and through said compaction tunnel, a ram, forming part of said packer, normally telescoped therein and retractably extendible therefrom in the direction of reciprocation of said packer, the ram having a leading end which forms a small portion of that of the packer as a whole when the ram is telescoped therein; motor means for reciprocating said packer through successive cycles of operation respectively comprising forward and return strokes, a standard cycle of operations commencing at a lead-off position with the ram telescoped in the packer and re-cycling means, responsive to mechanical stalling of the packer in the forward stroke of a standard cycle of operations, for terminating the forward stroke, returning said packer to its lead-off position, and initiating a special cycle of operations comprising forward and return strokes in which the forward stroke is effected with the ram extended.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
195 words
Waste compacting apparatus comprising: a hopper; a compaction tunnel communicating with said hopper and providing an outlet for waste deposited therein; a packer located and reciprocable through successive forward and return strokes to advance waste from the hopper into and through said compaction tunnel, the waste being compacted in its transit through said compaction tunnel; a ram forming part of said packer and normally telescoped therein and retractably extendible therefrom in the direction of reciprocation of said packer; the ram having a leading end which forms a portion of that of the packer as a whole when the ram is telescoped therein; motor means for reciprocating said packer through successive cycles of operations respectively comprising forward and return strokes, a standard cycle of operations commencing at a leadoff position with the ram telescoped as aforesaid, and re-cycling means responsive upon mechanical stalling of the packer in the forward stroke of a standard cycle of operations, to terminate said forward stroke, return said packer to its lead-off position, and to initiate a special cycle of operations comprising forward and return strokes in which the forward stroke is effected from said lead-off position with the ram extended.
Claim 2
Dependent Claim
195 words
Waste compacting apparatus comprising: a hopper; a compaction tunnel communicating with said hopper and providing an outlet for waste deposited therein; a packer located and reciprocable through successive forward and return strokes to advance waste from the hopper into and through said compaction tunnel, the waste being compacted in its transit through said compaction tunnel; a ram forming part of said packer and normally telescoped therein and retractably extendible therefrom in the direction of reciprocation of said packer; the ram having a leading end which forms a portion of that of the packer as a whole when the ram is telescoped therein; motor means for reciprocating said packer through successive cycles of operations respectively comprising forward and return strokes, a standard cycle of operations commencing at a leadoff position with the ram telescoped as aforesaid, and re-cycling means responsive upon mechanical stalling of the packer in the forward stroke of a standard cycle of operations, to terminate said forward stroke, return said packer to its lead-off position, and to initiate a special cycle of operations comprising forward and return strokes in which the forward stroke is effected from said lead-off position with the ram extended.
Claim 3
Dependent Claim
27 words
Waste compacting apparatus as defined in claim 1 wherein: said re-cycling means initiates only a single special cycle in each response to mechanical stalling of the packer.
Claim 4
Dependent Claim
33 words
Waste compacting apparatus as defined as claim 1 wherein: said re-cycling means procures extension of said ram during the return of said packer to its lead-off position after termination of said forward stroke.
Claim 5
Dependent Claim
96 words
Waste compacting apparatus as defined in claim 1 wherein said re-cycling means includes switching means: a. for terminating the forward stroke when the packer is stalled as aforesaid; b. for thereafter procuring return of said packer to its lead-off position; c. for initiating extension of said ram from said packer while it is being returned to the lead-off position; d. for thereafter initiating a forward stroke from the lead-off position with said ram extended from said pAcker as aforesaid, and e. for restoring said packer to standard operation upon completion of said special cycle of operations.
Claim 6
Dependent Claim
36 words
Waste compacting apparatus as defined in claim 1 wherein: said packer has a scoop-shaped leading end for gathering waste from the hopper and directing it into said compaction tunnel during the forward stroke of the packer.
Claim 7
Dependent Claim
52 words
Waste compacting apparatus as defined in claim 1 wherein: said compaction tunnel has a progressively reducing cross-section over a portion of its length, its widest point being at its inlet end which communicates with said hopper and which corresponds generally in area to the area of the leading end of the packer.
Claim 8
Dependent Claim
45 words
Waste compacting apparatus as defined in claim 4 wherein said switching means includes: means for initiating retraction of said ram to its telescoped position in the packer while the packer is being returned to its lead-off position following the forward stroke of a special cycle.
Claim 9
Dependent Claim
157 words
Waste compacting apparatus as defined in claim 4 wherein: said re-cycling means includes switching means for initiating retraction of said ram to its telescoped position in the packer while the packer is being returned to its lead-off position following the forward stroke of a special cycle. said re-cycling means initiating only a single special cycle in each response to mechanical stalling of the packer and procures extension of said ram during the return of said packer to its lead-off position after termination of said forward stroke; said packer has a scoop-shaped leading end for gathering waste from the hopper and directing it into said compaction tunnel during the forward stroke of the packer, and said compaction tunnel has a progressively reducing cross-section over a portion of its length, its widest point being at its inlet end which communicates with said hopper and which corresponds generally in area to the area of the leading end of the packer.
