Abstract
Abstract A refuse compactor has an upright housing whose internal compacting chamber is accessible by a door provided in its circumferential wall. A compacting head fills the cross section of the chamber and is guidedly slidable in axial direction thereof. A power source and motion-transmitting arrangement are provided for advancing the compacting head towards an end wall of the housing to thereby compact refuse between the end wall and the compacting head, and for subsequently withdrawing the compacting head in direction away from the one end wall for enabling removal of the compacted refuse.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
205 words
A refuse compactor comprising, in combination, a housing provided with an internal chamber and including a circumferential wall having an inner side and a pair of axially spaced end walls bounding said chamber; a compacting head having cross-sectional dimensions substantially corresponding to those of said chamber and being arranged therein for guided sliding advancement in axial direction thereof; a door provided in said circumferential wall communicating with said chamber so as to enable introduction into the latter of refuse to be compacted; advancing means associated with said compacting head tiltably suspending the same in said chamber and operative for effecting advancement of said compacting head in axial direction of said chamber to thereby compact refuse between said compacting head and one of said end walls; and guide means including a peripheral wall projecting from said compacting head towards the other of said end walls along and proximal to said inner side of said circumferential wall, for preventing tilting of said compacting head relative to the axis of said chamber in response to advancement axially of said chamber, and for offsetting forces acting upon said compacting head in the peripheral regions of the latter which are further from said axis and closer to said circumferential wall.
Claim 2
Dependent Claim
205 words
A refuse compactor comprising, in combination, a housing provided with an internal chamber and including a circumferential wall having an inner side and a pair of axially spaced end walls bounding said chamber; a compacting head having cross-sectional dimensions substantially corresponding to those of said chamber and being arranged therein for guided sliding advancement in axial direction thereof; a door provided in said circumferential wall communicating with said chamber so as to enable introduction into the latter of refuse to be compacted; advancing means associated with said compacting head tiltably suspending the same in said chamber and operative for effecting advancement of said compacting head in axial direction of said chamber to thereby compact refuse between said compacting head and one of said end walls; and guide means including a peripheral wall projecting from said compacting head towards the other of said end walls along and proximal to said inner side of said circumferential wall, for preventing tilting of said compacting head relative to the axis of said chamber in response to advancement axially of said chamber, and for offsetting forces acting upon said compacting head in the peripheral regions of the latter which are further from said axis and closer to said circumferential wall.
Claim 3
Dependent Claim
40 words
A refuse compactor as defined in claim 1 wherein said housing is an upright housing, said end walls being the top wall and the bottom wall of said housing, respectively, and said one end wall being said bottom end wall.
Claim 4
Dependent Claim
35 words
A refuse compactor as defined in claim 2; said advancing means comprising motive means and motion-transmitting means associated with said motive means and said compacting head for transmitting motion from the former to the latter.
Claim 5
Dependent Claim
48 words
A refuse compactor as defined in claim 3; and further comprising disabling means operatively associated with said door and with said advancing means for disabling the latter in response to opening of the former so as to preclude advancement of said compacting head when said door is open.
Claim 6
Dependent Claim
25 words
A refuse compactor as defined in claim 3, said motive means comprising a hydraulic cylinder-and-piston unit and a source of power for operating the same.
Claim 7
Dependent Claim
32 words
A refuse compactor as defined in claim 5, said motion-transmitting means including a universal drive arrangement mounted on said compacting head and a transmission rod connecting said drive arrangement with said unit.
Claim 8
Dependent Claim
27 words
A refuse compactor as defined in claim 5, said source of power including a hydraulic pump and a motor associated with said pump for operating the same.
Claim 9
Dependent Claim
17 words
A refuse compactor as defined in claim 5, said hydraulic cylinder-and-piston unit being of the double-acting type.
Claim 10
Dependent Claim
64 words
A refuse compactor as defined in claim 2, said door being hinged for pivoting movement about an upright axis paralleling that of said housing, and having a lower end portion provided with a laterally projecting platform which overlies said bottom wall interiorly of said chamber when said door is closed, and which platform is adapted to support bag-shaped receptacles for refuse to be compacted.
Claim 11
Dependent Claim
78 words
A refuse compactor as defined in claim 9; further comprising a fEed hopper hingedly mounted on said circumferential wall above said door and hingedly movable between an inoperative position in which it is upwardly retracted so as not to interfere with movement of said door, and an operative position in which it is positioned above said platform when said door is open so as to feed refuse to be compacted into a bag-shaped receptacle supported on said platform.
Claim 12
Dependent Claim
44 words
A refuse compactor as defined in claim 9; said platform having slight freedom of movement in direction towards said lower end wall so as to firmly abut against and be supported by the same when said door is closed and refuse is being compacted.
Claim 13
Dependent Claim
34 words
A refuse compactor as defined in claim 2; and further comprising drain means below the level of said said end wall for collecting and draining liquid expressed during compacting of refuse in said chamber.
Claim 14
Dependent Claim
50 words
A refuse compactor as defined in claim 9; and further comprising a bag-shaped receptacle arranged to be supported on sad platform for accommodating, prior to closing of said door, refuse to be compacted and for accommodating the compacted refuse so as to facilitate subsequent removal thereof from s said platform.
