Publication number: 20230089881Abstract: Removable cab toe boxes are described herein to provide increased comfort to an operator while still allowing a cab to be rotated upwards to provide access to equipment below the cab. The removable toe boxes are removably affixed to the cab and, when installed, may provide at least a partial seal to prevent or reduce the amount of dirt or dust entering the cab. When the toe boxes are removed, equipment may move through the space created from the removal of the toe boxes to allow the cab to rotate.Type: ApplicationFiled: August 31, 2022Publication date: March 23, 2023Applicant: Caterpillar SARLInventors: Benjamin Michael Cheek, Rafael dela Rosa, Sage Frederick Smith

Publication number: 20220136204Abstract: An implement control system may include one or more first actuators configured to selectively raise or lower a work implement of a machine and one or more second actuators configured to tilt the work implement. The implement control system may include an operator control configured for manipulation in one or more motions. The implement control system may include a controller configured to, based on a particular motion of the one or more motions, selectively cause actuation of the one or more first actuators in a first mode or the one or more second actuators in a second mode.Type: ApplicationFiled: October 30, 2020Publication date: May 5, 2022Applicant: Caterpillar Inc.Inventors: Jeremy KUSHNER, Christopher Mark ELLIOTT, Sage Frederick SMITH

Patent number: 8960227Abstract: A tank for a hydraulic fluid has a housing with opposed end walls and side walls defining an interior chamber. A primary baffle is disposed inside the housing and divides the interior chamber into an inlet chamber and an outlet chamber, with a primary gap between the primary baffle and the housing fluidly communicating between the inlet chamber and the outlet chamber. The primary baffle further defines a contact surface facing the inlet chamber and has first and second weirs which extend into the inlet chamber. A first fluid inlet fluidly communicates with the inlet chamber and is oriented along a first inlet axis that intersects the contact surface, while a fluid outlet communicates with the outlet chamber. The tank produces an interior flow that mixes and deaerates the fluid as it travels from the first fluid inlet to the fluid outlet.Type: GrantFiled: March 16, 2012Date of Patent: February 24, 2015Assignee: Caterpillar SARLInventors: Sage Frederick Smith, Brian Franklin Taggart, Xuekui Lan, Weixue Tian

Patent number: 8869516Abstract: A machine includes an internal combustion engine disposed within an engine compartment and supported on a machine frame. An exhaust stack has an inlet fluidly connected to an exhaust manifold of the internal combustion engine and an outlet in fluid communication with ambient air. A diesel particulate filter is disposed along the exhaust stack. A cooling package includes at least one heat exchanger and a blower fan. The blower fan is configured to blow cooling air from the engine compartment sequentially through the at least one heat exchanger and an outlet of the cooling package. Exhaust gas exiting the exhaust stack outlet is mixed with the cooling air exiting the cooling package outlet in a high temperature zone surrounding the exhaust stack outlet to form a fluid mixture, and a temperature of the fluid mixture at a perimeter of the high temperature zone is below 200 degrees Celsius.Type: GrantFiled: November 3, 2010Date of Patent: October 28, 2014Assignee: Caterpillar SARLInventors: Sage Frederick Smith, John Edward Preble, Jr., Terry Marlin Smith, Jr.

Patent number: 8556014Abstract: A skid steer machine includes an operator cage supported on a skid steer machine frame, a pair of lift arms pivotably attached to the skid steer machine frame behind the operator cage and extending longitudinally on both sides of the operator cage, and a rear mounted engine compartment supported on the skid steer machine frame. The rear mounted engine compartment includes an internal combustion engine, a diesel particulate filter fluidly connected to the internal combustion engine and positioned between the internal combustion engine and the operator cage, and a cooling package having a predominantly horizontal orientation. The cooling package is at a higher location within the rear mounted engine compartment than the diesel particulate filter.Type: GrantFiled: November 3, 2010Date of Patent: October 15, 2013Assignee: Caterpillar Inc.Inventors: Sage Frederick Smith, John Edward Preble, Jr., Kimberly Melissa Stanek

Publication number: 20130226415Abstract: A skid steer type machine is equipped with an overheat protection algorithm that keeps the machine productive even when the hydraulic system is in an overheated condition. When an elevated hydraulic fluid temperature is detected, an electronic controller derates a pump of the hydraulic system to limit pump output to a reduced flow rate down from a rated flow rate. The hydraulic fluid tends to cool down when the pump is derated, but the machine remains productive while the hydraulic system is cooling down.Type: ApplicationFiled: February 28, 2012Publication date: August 29, 2013Applicant: CATERPILLAR INC.Inventors: Sage Frederick Smith, Brian Franklin Taggart, Clayton Lucas Padgett, John Sale Bibb, III, Michael Charles Rossi, Kimberly Melissa Stanek

Patent number: 8479498Abstract: A machine includes an internal combustion engine disposed within an engine compartment and supported on a machine frame. An exhaust stack has an inlet fluidly connected to an exhaust manifold of the internal combustion engine and an outlet in fluid communication with ambient air. A diesel particulate filter is disposed along the exhaust stack, and the machine includes an active regeneration system for regenerating the diesel particulate filter. A cooling package including at least one heat exchanger and a blower fan. The blower fan is configured to blow cooling air from the engine compartment sequentially through the at least one heat exchanger and an outlet of the cooling package. Exhaust gas exiting the exhaust stack outlet is mixed with the cooling air exiting the cooling package outlet in a high temperature zone surrounding the exhaust stack outlet to form a fluid mixture.Type: GrantFiled: November 3, 2010Date of Patent: July 9, 2013Assignee: Caterpillar SARLInventors: Sage Frederick Smith, John Edward Preble, Jr.

Publication number: 20130000072Abstract: A clamping assembly for permitting passage of an elongated member through a wall. The clamping assembly includes a first clamping member and a second clamping member. The first clamping member includes a first arm extending outwardly from a first central portion of the first clamping member. The second clamping member includes a second arm extending outwardly from a second central portion of the second clamping member. The second clamping member is configured to be removably engaged with the first clamping member, such that the first arm and the second arm define an opening for permitting passage of the elongated member.Type: ApplicationFiled: June 30, 2011Publication date: January 3, 2013Applicant: Caterpillar Inc.Inventors: Gareth Leuan Jones, Sage Frederick Smith, John William Salay
