Patent number: 12123332Abstract: An exhaust discharge system is disclosed. The exhaust discharge system comprises an exhaust stack including a first conduit and a second conduit. The first conduit defines a first flow passageway and arranged around a first longitudinal axis. The first conduit including a skirt portion and a body portion disposed downstream of the skirt portion, and the skirt portion is oriented to slope outward from the body portion. The second conduit is disposed downstream of the first conduit. The second conduit defines a second flow passageway and is arranged around a second longitudinal axis, the second conduit includes a sidewall and an exit port, the exit port having an exit-port cross-section, wherein the exit-port cross-section is oblong in shape. The second longitudinal axis is disposed at an intersection angle to the first longitudinal axis, the intersection angle in a range of 125° to 150°. The exhaust stack is configured to convey treated exhaust from the skirt portion to the exit port.Type: GrantFiled: June 8, 2023Date of Patent: October 22, 2024Assignee: Caterpillar Inc.Inventors: Saad Hasan, Gerald W.

Patent number: 10316557Abstract: An interlock lever for actuating a latch member of a machine is disclosed. The latch member is configured to lock a hood of the machine in a closed position thereof. The machine has an input member being movable in a first direction to move the hood towards an opened position and a second direction to move the hood towards the closed position. The interlock lever includes a body coupled to a frame of the machine and a slot defined in the body. The body is movable between a first position and a second position. In the second position of the body, the slot allows movement of the input member in the first direction and actuates the latch member to allow the hood to move from the closed position. In the first position of the body, the slot prevents movement of the input member in the first direction.Type: GrantFiled: January 21, 2015Date of Patent: June 11, 2019Assignee: Caterpillar Inc.Inventors: Phillip A. Hartz, Gerald W. Gavin, Daniel A. Hatfield, Brian P. Budzynski, Christopher M. Runestad
