Abstract
Abstract A refuse vehicle having improved compacting and unloading means is provided. A refuse storage space of the vehicle has a rear unloading door and a front opening through which refuse is loaded into the storage space. A small compacting plunger pushes the refuse through the loading opening into the space and compacts it. A rigid cover member is hinged to the plunger and is pivotally raised when the plunger is extended fully into the storage area and the unloading door is open to enable the plunger and cover member to periodically unload the refuse from the storage space by moving the plunger through a longer stroke through the storage space and to a point near the unloading door. The small plunger enables high compacting pressures to be achieved and yet the combination of the plunger and cover member enables the vehicle to be unloaded without the need for tilting the body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
185 words
A refuse-collecting vehicle comprising wall means forming a refuse storage space, said wall means also defining a loading opening and an unloading opening, a closure member for said unloading opening, means forming a loading space adjacent said loading opening, a compacting plunger having a compacting face, means for reciprocating said plunger through said loading space between a retracted position in which the plunger face is spaced from said loading opening and a compacting position in which the plunger face is near said loading opening, said reciprocating means also being effective to move said plunger to an unloading position in said storage space with the plunger face near said closure member, a substantially rigid cover member connected with said plunger, said cover member being of a size to substantially cover said loading space behind said plunger face when said plunger face is in the compacting position adjacent said loading opening, and means for raising said cover member within said storage space when said plunger is moved toward the unloading position near said closure member, to enable said cover member to facilitate unloading of the storage space.
Claim 2
Dependent Claim
185 words
A refuse-collecting vehicle comprising wall means forming a refuse storage space, said wall means also defining a loading opening and an unloading opening, a closure member for said unloading opening, means forming a loading space adjacent said loading opening, a compacting plunger having a compacting face, means for reciprocating said plunger through said loading space between a retracted position in which the plunger face is spaced from said loading opening and a compacting position in which the plunger face is near said loading opening, said reciprocating means also being effective to move said plunger to an unloading position in said storage space with the plunger face near said closure member, a substantially rigid cover member connected with said plunger, said cover member being of a size to substantially cover said loading space behind said plunger face when said plunger face is in the compacting position adjacent said loading opening, and means for raising said cover member within said storage space when said plunger is moved toward the unloading position near said closure member, to enable said cover member to facilitate unloading of the storage space.
Claim 3
Dependent Claim
26 words
A vehicle according to claim 1 characterized by said cover member being connected to said plunger by having an edge pivotally attached to said compacting plunger.
Claim 4
Dependent Claim
44 words
A vehicle according to claim 2 characterized by said raising means for said cover comprising means forming a ramp within said storage space, and means connected to said cover member engageable with said ramp to pivot said cover member upwardly around the pivotal attachment.
Claim 5
Dependent Claim
20 words
A vehicle according to claim 3 characterized by said means for reciprocating said compacting plunger comprising a telescopic, fluid-operated cylinder.
Claim 6
Dependent Claim
63 words
A vehicle according to claim 2 characterized by said raising means comprises two ramps positioned at sides of said storage space between the loading opening and the unloading opening, and a pair of plunger face extensions at the ends of the plunger face, said extensions being rigidly affixed to said cover member and engageable with said ramps to pivot said cover member upwardly.
Claim 7
Dependent Claim
24 words
A vehicle according to claim 1 characterized by roller means carried by said compacting plunger to facilitate movement of said plunger during reciprocation thereof.
Claim 8
Dependent Claim
178 words
A load-carrying vehicle comprising wall means forming a storage space for the load, said wall means further defining loading and unloading openings for the space, a closure member for said unloading opening, means forming a loading space adjacent said loading opening, a compacting plunger having a plunger face, means for reciprocating said plunger through said loading space between a retracted position in which the plunger face is spaced from said loading opening and a compacting position in which the plunger face is near said loading opening, said reciprocating means also being effective to move said plunger to an unloading position in said storage space with the plunger face near said closure member, a rigid cover pivotally connected with said plunger and extending behind said plunger face, and means for pivotally raising said rigid cover within said storage space when said plunger is moved toward said closure member and said plunger and said cover are within said storage space, to enable said plunger and said rigid cover to push any load in said storage space out the unloading opening.
Claim 9
Dependent Claim
178 words
A load-carrying vehicle comprising wall means forming a storage space for the load, said wall means further defining loading and unloading openings for the space, a closure member for said unloading opening, means forming a loading space adjacent said loading opening, a compacting plunger having a plunger face, means for reciprocating said plunger through said loading space between a retracted position in which the plunger face is spaced from said loading opening and a compacting position in which the plunger face is near said loading opening, said reciprocating means also being effective to move said plunger to an unloading position in said storage space with the plunger face near said closure member, a rigid cover pivotally connected with said plunger and extending behind said plunger face, and means for pivotally raising said rigid cover within said storage space when said plunger is moved toward said closure member and said plunger and said cover are within said storage space, to enable said plunger and said rigid cover to push any load in said storage space out the unloading opening.
Claim 10
Dependent Claim
82 words
A vehicle according to claim 7 characterized by said raising means comprising means forming a ramp adjacent each side of said storage space and extending in the direction of movement of said compacting plunger, said rigid cover having depending means extending downwardly on each side of said plunger face and engageable with said ramps when said compacting plunger is moved toward the unloading position to raise said rigid cover as the plunger moves further toward thE unloading position in said storage space.
Claim 11
Dependent Claim
17 words
A vehicle according to claim 8 characterized by said depending means forming extensions of said plunger face.
Claim 12
Dependent Claim
19 words
A vehicle according to claim 8 characterized by rollers carried by said depending means to engage said slanted surfaces.
