Abstract
Abstract A self-loading truck having many uses and particularly suitable for transferring the contents of containers onto a truck and restoring the empty containers alongside the path of travel. Swivelling boom means operating in view of the truck driver and controlled by him while seated at the driver station includes both manual and semi-automatic controls for picking up containers from either side of the truck and emptying them into the cargo compartment by self-centering boom control means. The boom components are powered by pressurized fluid supplied by a driving engine which speeds up and resumes idling automatically during the cargo handling cycle. For trash handling operations, the power boom is supported on one forward corner of the truck chassis for swivelling movement cross-wise of the truck in full view of the driver and operates to dump trash into the truck from containers resting at the curb on either side of the street.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
An engine-powered self-loading trash truck driven and loaded by the truck driver while seated in a truck driving station, said truck having a chassis with a pair of steerable front wheels and a pair of engine-driven rear wheels supporting the respective ends of a large trash storage chamber having a top inlet, a driving station and a boom supporting station forwardly of said steerable front wheels on the opposite forward corners of said chassis, extendable boom means supported close to street level at one forward chassis corner and in full view of the driver seated at said truck driving station, driver controllable power means for extending and pivoting said boom means horizontally in the lowered position thereof crosswise of the forward end of said truck and including means to pick up an unattached trash container at ground level from either lateral side of said truck, power means for pivoting said boom means and a trash container carried thereby upwardly and rearwardly, and power means on said boom means for thereafter upending a trash container and dumping its contents into said storage chamber inlet.
Claim 2
Dependent Claim
183 words
An engine-powered self-loading trash truck driven and loaded by the truck driver while seated in a truck driving station, said truck having a chassis with a pair of steerable front wheels and a pair of engine-driven rear wheels supporting the respective ends of a large trash storage chamber having a top inlet, a driving station and a boom supporting station forwardly of said steerable front wheels on the opposite forward corners of said chassis, extendable boom means supported close to street level at one forward chassis corner and in full view of the driver seated at said truck driving station, driver controllable power means for extending and pivoting said boom means horizontally in the lowered position thereof crosswise of the forward end of said truck and including means to pick up an unattached trash container at ground level from either lateral side of said truck, power means for pivoting said boom means and a trash container carried thereby upwardly and rearwardly, and power means on said boom means for thereafter upending a trash container and dumping its contents into said storage chamber inlet.
Claim 3
Dependent Claim
109 words
A self-loading truck as defined in claim 1 characterized in the provision of a manually operable control means for said boom means beside a seated driver in said driving station and normally biased to a neutral position, said control means including means manually shiftable in opposite directions along three axes at right angles to one another, said control means including switch and control means operatively connected to the respective ones of said power means operable to extend and retract said boom means and to pivot it in either direction about the vertical and horizontal axes tHereof and corresponding to the direction in which said manually shiftable means is shifted.
Claim 4
Dependent Claim
88 words
A self-loading truck as defined in claim 2 characterized in the provision of manually operated switch means and associated means connected to the power operating means for said boom means and operable when activated by the operator to operate said boom means through an automatic cycle which includes retraction of the boom, pivoting the boom horizontally in either direction to a preselected position, pivoting the boom vertically upward to a preselected container dumping position, and thereafter upending a container to dump its contents into said storage chamber inlet.
Claim 5
Dependent Claim
77 words
A self-loading truck as defined in claim 3 characterized in that said means for upending a trash container includes reversible motor means and container level control sensing means for maintaining a container upright while being elevated to dumping position, and means for deactivating said level sensing control means and for activating said container upending power means in a direction to dump a container when the container is in a preselected elevated position opposite said storage chamber inlet.
Claim 6
Dependent Claim
56 words
A self-loading truck as defined in claim 1 characterized in that said power means for upending a trash container includes reversible motor means and container level control sensing means operable to drive said container upending motor means in either direction as necessary to maintain a container generally upright while being elevated to said storage chamber inlet.
Claim 7
Dependent Claim
49 words
A self-loading truck as defined in claim 5 characterized in the provision of means for deactivating said level control means automatically as said boom means reaches a dumping position at said storage inlet and for activating said container upending power means to dump the container contents into said inlet.
Claim 8
Dependent Claim
36 words
A self-loading truck as defined in claim 1 characterized in the provision of hydraulic pump means driven by said truck engine to supply pressurized fluid to operate each of said power means for said boom means.
Claim 9
Dependent Claim
61 words
A self-loading truck as defined in claim 7 characterized in the provision of means responsive to the actuation of said power means for said boom means to increase the fuel supply to said engine so long as said boom means is in operation and for restoring said fuel supply to engine idling requirements when said boom means is not in use.
Claim 10
Dependent Claim
60 words
A self-loading truck as defined in claim 1 characterized in that said container pickup means includes a pair of power-operated clamping jaws for gripping and releasing a trash container supported on the outer end of said boom means by reversible motor means having a horizontal axis and operating to rotate a container in a vertical plane about said motor axis.
Claim 11
Dependent Claim
72 words
A self-loading truck as defined in claim 9 characterized in the provision of container level control sensing means for operating said motor means to maintain a container upright until elevated above said storage chamber inlet, and means responsive to the arrival of a container to said upending position to deactivate level control means and utilizing said motor means to upend a container and dump the contents thereof into said storage chamber inlet.
