Abstract
Abstract A solid waste removal vehicle having a front loading mechanism for collecting, comminuting and compacting waste while being transferred into a container. The vehicle is further characterized by a driver cab and a loading assembly normally positioned in the path of ejection of the waste from the container, the cab and assembly each being independently swingable transversely of the path to an offset and unobstructing position to satisfy loading and ejecting conditions. A mechanism responsive to the swing of the cab automatically maintains the latter in its normal forward-facing position at all times to thereby provide optimum visibility for the driver or operator. Moreover, means are provided for steering the vehicle during normal and offset positions of the cab.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
218 words
In a waste pickup and ejecting vehicle having a waste container with an opening therein at the front of said vehicle, and means in said container for ejecting waste through said opening, the combination of a waste-receiving channelled ramp having its upper end communicating with the lower portion of said opening and its lower end extending forwardly of the latter, means carried by said ramp for conveying waste upwardly thereof and into said opening, a forward-facing driver cab positioned above the communicating end of said ramp and in front of the upper portion of said opening; means for swinging said cab to a position to expose said opening; said means carried by said ramp for conveying waste comprising a plurality of screws disposed longitudinally of said ramp channels for thrusting said waste upwardly thereof, said screws being rotatable substantially in a common plane; additional means comprising a plurality of yieldably mounted parallel bars extending longitudinally relative to said ramp for movement toward and away from said screws, said bars each being bodily rotatable in a plane disposed at right angles to said common plane, and means for rotating alternate bars successively into engagement with said waste to thrust the latter upwardly toward said opening whereby a convergent thrust is produced to supplement the upward thrust of said screws.

Claim 3
Dependent Claim
37 words
A vehicular pickup mechanism as defined in claim 1 wherein said ramp comprises at least one pair of parallel troughs, and wherein said screw means comprises a pair of oppositely pitched screws respectively mounted in said troughs.
Claim 4
Dependent Claim
41 words
A vehicular waste pickup mechanism as defined in claim 2 and further comprising means for rotating said oppositely pitched screws in opposite directions to center the waste material above and between the screws as it is conveyed longitudinally by said screws.
Claim 5
Dependent Claim
81 words
A vehicular pickup mechanism as defined in claim 1 and further comprising means for collecting and delivering waste to the lower portion of said ramp and associated screw means, said collecting and delivering means also including a plurality of parallel fingers each bodily rotatable in a plane disposed at right angles to said common plane, and means for rotating alternate fingers of said collecting and delivering means successively into engagement with said waste to collect and transfer it to said ramp.
Claim 6
Dependent Claim
35 words
A waste pickup and ejecting vehicle as defined in claim 1 and further comprising means for swinging said ramp upwardly to expose said opening when said cab is in its position to expose said opening.
Claim 7
Dependent Claim
24 words
A waste pickup and ejecting vehicle as defined in claim 1 and further comprising means operable from said swingable cab for steering said vehicle.
