Patent number: 6113193Abstract: An apparatus and method for automatically reducing engine exhaust noise from a dump truck including a heated bed without the additional requirement of diverting the flow of exhaust through a separate muffler apparatus. An engine noise reduction system associated with the truck includes an engine control unit for controlling high idle engine speed parameters of the truck engine. When the truck bed is raised upwardly from an initial lowered position to release a material load from the bed, or hydraulics associated with the truck bed are actuated to raise the bed, the engine control unit automatically lowers the high idle engine speed of the truck engine to reduce engine noise from the truck engine. The high idle engine speed of the truck engine is automatically reset to the standard setting when the truck bed returns to the initial lowered position.Type: GrantFiled: February 2, 1999Date of Patent: September 5, 2000Assignee: Caterpillar Inc.Inventor: Joseph D. Kunzeman

Patent number: 5797656Abstract: An apparatus is disclosed for diverting a flow of exhaust from an engine of a truck having a truck bed and a muffler system, with the truck bed having a duct system. The apparatus includes an inlet for receiving the flow of exhaust from the engine. The apparatus further includes a first outlet connected to the muffler system and a second outlet connected to the duct system. The apparatus additionally includes a diverter member positionable between a first position and a second position, wherein (1) fluid communication between the inlet and the first outlet is prevented when the diverter member is positioned in the first position, and (2) fluid communication between the inlet and the second outlet is prevented when the diverter member is positioned in the second position. Moreover, the apparatus includes an air cylinder for moving the diverter member between the first position and the second position.Type: GrantFiled: May 2, 1996Date of Patent: August 25, 1998Assignee: Caterpillar Inc.Inventors: Zachary A.

Patent number: 5379801Abstract: Exhaust directing mechanisms are useful for directing exhaust gas flow from an inlet to either a vehicle dump body or a muffler means. A valve mechanism for a vehicle includes a valve body having a valving element mounted within the valve body and being rotatable to a first position upon movement of a dump body to a raised position to direct exhaust from an engine to a muffler. With the dump body in the lowered position the valving element is in the second position to direct exhaust to the dump body. This arrangement of components provides for rotation of the valving element to direct exhaust flow to the dump body or to the muffler.Type: GrantFiled: May 5, 1994Date of Patent: January 10, 1995Assignee: Caterpillar Inc.Inventors: James W. Reinhart, Richard D. Walker

Patent number: 4978068Abstract: An apparatus and method for heating snow traction-improving material contained in a bin mounted on a motor vehicle, such as a truck. Panels are attached to the side of the bin to form a sealed cavity surrounding the bin. Hot exhaust from the motor vehicle engine is then piped into and flows through the cavity so as to heat the cavity, whereby heat from the cavity warms the contents of the bin. The exhaust then flows out an exit portal from the cavity to permit continued flow-through. Provision is made to form holes in any buttress supports, supporting the bin on the truck, which might obstruct the flow of hot exhause. Finally, a drain is provided, allowing any condensation formed in the cavity to escape.Type: GrantFiled: May 18, 1990Date of Patent: December 18, 1990Inventor: Stanley W. Eldridge

Patent number: 4273381Abstract: A dump body for mounting on the frame of a vehicle is disclosed. The dump body comprises a floor, side walls and a front wall secured together to form an integral unit, a rear gate closing the back of the unit. The floor is composed of a central, elongated plate and a pair of elongated lateral plates, each of smaller thickness than the central plate, so that the latter will resist abrasion for a longer time, where abrasion is most likely to occur and yet reducing the weight of the dump body. The lateral plates extend underneath and overlap the central plate and are bent to form integral, longitudianally-extending hollow beams welded to the central plate for strengthening the unit.Type: GrantFiled: October 27, 1978Date of Patent: June 16, 1981Inventors: Jean-Marie Bibeau, Marcel Bibeau
