| 20080257672 | Torque-Limited Electric Servo System for Deploying a Vehicle Snow Chain Traction System - A single unit of the new deployment system includes a housing to which an electric drive motor is externally mounted. The deployment system for each vehicle requires at least a pair of deployment units: one each for right and left wheels. Each unit includes a reversable electric drive motor having an armature shaft; an intermediate drive shaft; a worm axially affixed to the intermediate drive shaft; an output shaft; a shock damper affixed to the output shaft; a worm gear affixed to the shock damper, the worm gear meshing with the worm, and providing rotational locking for said output shaft; and a deployment arm coupled to the output shaft, the deployment arm having rotatably mounted thereto a friction drive disc, said friction drive disc having peripherally attached thereto a plurality of chain segments. Torque applied to the output shaft by the electric motor is limited either by a spring-loaded clutch axially mounted on the intermediate drive shaft or by a circuit which limits current drawn by the electric drive motor to a preset maximum. | 10-23-2008 |
| 20080277903 | APPARATUS FOR RAISING A SPRING ARM ON A TRAILER HITCH - An apparatus for raising a spring arm of a trailer hitch. The apparatus may include a lift, such as a jack, for attaching to a tongue of a trailer. A link member may be pivotally attached to the lift. The link member may also be pivotally attached to a bracket which may be attached to the spring arm. A brace member may be attached to the link member on an end opposite the bracket. As the lift raises the link member, the link member may pivot about the brace member such that movement of the bracket may be amplified as compared to movement of the lift. Moreover, lifting of the spring arm can be easily accomplished. | 11-13-2008 |
| 20080277961 | Tarping system for open top containers - A relatively lightweight tarping system for use with trailers or other open top containers includes first and second spaced frame members and an elongated flexible member such as a cable or chain connected to and extending therebetween. A tarpaulin may be mounted thereon so that the frame members, flexible member and tarpaulin are pivotable between a covered position atop the open top container and an uncovered position. A four-bar linkage is preferably used in combination with a rotational drive mechanism to provide various advantages in rotating the tarpaulin assembly between the covered and uncovered positions. A width adjustment mechanism is provided to provide usage with trailers or other open top containers of different widths. An improved seal is provided between the tarpaulin and container. | 11-13-2008 |
| 20080303312 | CROSS-MEMBER FOR A TRAILER FRAME AND A TRAILER FRAME INCORPORATING THE SAME - A cross-member for a trailer frame and a frame incorporating the same. The cross-member extends between longitudinally aligned rails designed to pivotally support a dumping body thereon. The cross-member includes a cylindrical tube having a wall defining a bore therethrough. A planar member is received within the bore and is axially aligned therewith. The tube includes one or more axially aligned openings proximate a central region thereof. The planar member is disposed intermediate the openings and is aligned axially with the openings. The cross-member is substantially rigid under tension and at least a portion thereof is flexible under torsion. | 12-11-2008 |
| 20090067965 | SIDE-LOADING REFUSE COLLECTION APPARATUS AND METHOD - An apparatus for collecting refuse, the apparatus comprising a vehicle having a frame formed as two substantially parallel members and a hopper secured to the frame. First and second bins may be connected by respective first and second dumping mechanisms to opposite, exterior sides of the hopper. The first and second dumping mechanisms may selectively and independently move respective first and second bins between stowed positions substantially below the hopper and dumping positions above the hopper. The width between the exterior extremes of the first and second bins when both are in stowed positions may substantially be defined by a summation of the width of the first bin, the distance between the outer extremes of the frame, and the width of the second bin. | 03-12-2009 |
