Patent number: 8960607Abstract: A pneumatic deployment device (“PDD”) assists in ejecting containerized cargo bundles from a cargo aircraft during an airdrop. The PDD includes a first structure affixed to the aircraft and a second moveable structure, and which is positioned against a cargo bundle, referred to as a CDS bundle. Typically, a series of CDS bundles are positioned along a line in the cargo hold of the aircraft. A pressurized tank provides compress gas to an airbag that is positioned between the first structure and the second structure. Upon reaching the drop location, the gas is release from the tank to the airbag via a hose, inflating the airbag. The airbag pushes the second structure against the CDS bundle, so that the cargo bundles are ejected faster from the aircraft than would otherwise occur.Type: GrantFiled: September 30, 2011Date of Patent: February 24, 2015Assignee: The Boeing CompanyInventors: John Dorris, III, John Anthony Skorupa, William Worden Cleary

In some embodiments, a bin handler is built in to the bucket or an automated arm is provided for dumping refuse cans or containers directly into the hopper. The refuse vehicles may have side-loading buckets on one or both sides of the vehicle and the vehicles may be single or multiple compartment vehicles.Type: GrantFiled: November 20, 2000Date of Patent: May 21, 2002Assignee: McNeilus Truck and Manufacturing, Inc.Inventors: Garwin McNeilus, Ronald E.

Patent number: 6368046Abstract: A material eject system includes an ejector mounted to a bed of a vehicle which is movable between a rear end and a forward end of the bed for ejecting material from the bed. The ejector is powered by a cylinder having different fluid volumes depending on the direction of motion of the cylinder. A control circuit operates with the ejector motor to automatically move the ejector through eject and return cycles. Further, the control circuit detects different positions of the cylinder and automatically operates the cylinder at different speeds to maintain a constant motor and ejector speed throughout the material eject cycle.Type: GrantFiled: March 19, 1999Date of Patent: April 9, 2002Assignee: Caterpillar Inc.Inventors: Steven Burnett, Peter F.

Patent number: 6302636Abstract: A refuse collection container for mounting on a vehicle. The container is particularly suitable for separating and compacting recyclable materials due to the provision of a longitudinally extending diagonal partition. The container has a pair of refuse receiving buckets preferably adapted to be raised into alignment with apertures in the front wall of the container. Recyclable materials, sorted by type in the buckets, are then moved into the container by a compactor blade in each bucket. Discharge of the materials is facilitated by providing for swinging movement of the partition prior to the vehicle being in the dumping position. The partition is extensible so that when positioned diagonally with respect to side walls of the container, the partition extends to the discharge end of the container.Type: GrantFiled: March 27, 2000Date of Patent: October 16, 2001Assignee: Markland Inc.Inventor: Alain Duron

Patent number: 6238167Abstract: An over-center ejector blade retaining system which automatically locks the ejector blade in a loading position when the ejector blade has been retracted into the load position by operation of the hydraulic cylinder or ram to which it is attached. Movement of the ejector blade into the load position rotates a lock plate attached to the vehicle body into engagement with a locking roller attached to the ejector blade thereby compressing a spring attached to the lock plate. Upon movement of the connection between the lock plate and the spring over the center of rotation of the lock plate, the compressive force on the spring is released and the ejector blade held in the load position. When the ejector blade is moved from the load position to discharge materials, the process is reversed and the lock plate held in an open position for again receiving the locking rollers upon the return of the ejector blade to the load position.Type: GrantFiled: March 19, 1999Date of Patent: May 29, 2001Assignee: Caterpillar S.A.R.L.Inventors: Peter M.

Patent number: 6176673Abstract: A work machine having a receptacle adapted to receive and carry loads is disclosed. The receptacle has a first lateral sidewall, a second lateral sidewall spaced apart from the first lateral sidewall, and a floor extending between the first lateral sidewall and the second lateral sidewall. The work machine further includes a tailgate which extends transversely from the first sidewall to the second sidewall, the tailgate being pivotable between a closed position which prevents loads from exiting a rear portion of the receptacle, and an open position which allows loads to exit the rear portion of the receptacle. The work machine yet further includes a cylinder movable between a first rod position and a second rod position and a linkage. The linkage of the tailgate in the closed position when the cylinder is located in the first rod position, and positions the tailgate in the open position when the cylinder is located in the second rod position.Type: GrantFiled: September 25, 1998Date of Patent: January 23, 2001Assignee: Caterpillar Inc.Inventors: John P. Moyna, Peter F. Prillinger, Christopher Smith, David A. Young

Patent number: 6155776Abstract: A method of controlling movement of an ejector plate and a tailgate which are operatively associated with a receptacle of a work machine is disclosed. The method includes the step of supplying pressurized fluid via a first fluid line to (i) a first intake port of a multi-stage cylinder, and (ii) a second intake port of a single-stage cylinder. The method further includes the step of moving the ejector plate a first distance with the multi-stage hydraulic cylinder between from a retracted position toward an extended position in response to the supplying step. The method yet further includes the step of preventing movement of the tailgate during the ejector plate first distance moving step. The method still further includes the step of moving the ejector plate a second distance with the multi-stage hydraulic cylinder toward the extended position in response to the supplying step. The ejector plate second distance moving step is performed after the ejector plate first distance moving step.Type: GrantFiled: September 25, 1998Date of Patent: December 5, 2000Assignee: Caterpillar Inc.Inventor: John P.

Patent number: 6146079Abstract: A hollow refuse storage body having a longitudinal axis is configured for mounting on a truck chassis. The body has a forward hopper section and a rear section with an open rear end. A tailgate is mounted to the rear section of the refuse storage body and is moveable between closed and open positions to seal and unseal the open rear end of the rear section of the refuse storage body. A hollow box-like load eject blade is mounted within the refuse storage body for reciprocating movement along the longitudinal axis along a bottom floor of the refuse storage body. A hollow box-like packer blade is mounted within the refuse storage body for reciprocating movement along the longitudinal axis overlapping an upper surface of the eject blade. A pair of single stage hydraulic cylinders are coupled in crisscross fashion between the refuse storage body and the packer blade for moving the packer blade over a first range of travel.Type: GrantFiled: November 1, 1999Date of Patent: November 14, 2000Assignee: Amrep, Inc.Inventor: Jose A.

Patent number: RE41126Abstract: A frame configuration that is particularly adaptable for use on a trailer such that the frame configuration is operable in both a tilt mode of operation and a dump mode of operation. An actuating mechanism includes a linear actuator that is supported on the frame by a bracket and a yoke that connects to a load bed to power the vertical movement of the load bed in both tilt and dump functions. The linear actuator is pivotally mounted to permit a re-positioning of the actuator into an inoperative position. The frame configuration is provided with an articulated tilt frame in which the tongue is pivoted thereto allowing the load bed to pivot about a tilt axis which can coincide with the wheel axis of the trailer. The bed frame can be locked to the tilt frame for tilting upon articulation with the tongue, while a disconnection of the bed frame from the tilt frame enables the bed frame to pivot about the dump axis to provide a dump function in addition to the tilt function.Type: GrantFiled: December 8, 2003Date of Patent: February 16, 2010Assignee: Innovations By Contract, Inc.Inventor: Joseph C.
