Patent number: 9853531Abstract: Some embodiments of a fan clutch system for use in a vehicle can provide efficient access to one or more components for inspection and service even after the fan clutch system is installed in the vehicle. In particular embodiments, the fan clutch system can include a fan clutch device and a coil retainer assembly that are removably mounted to a right-angle gear box assembly in a manner that permits a technician to accessing at least one component for inspection, repair, or replacement. The coil retainer assembly may at least partially house an electromagnetic coil for selective activation. The system may further include a fan clutch device removably mounted to the drive member of the gear box assembly.Type: GrantFiled: March 31, 2014Date of Patent: December 26, 2017Assignee: Kit Masters Inc.Inventors: Craig M. Swanson, Thomas M. Jagger

Patent number: 9086102Abstract: A clutch system may include in certain embodiments a clutch body attached to a drive member such as a drive pulley, wherein the clutch body may be removed from the drive member without disassembling the clutch body. In various embodiments, the clutch body may include two clutch plates which enclose a spring-loaded pneumatic reciprocating assembly that in operation causes the plates to selectively separate and engage one another. In certain embodiments, the clutch body may be readily attached to a associated drive pulley in a single step by installation of a single set of fasteners.Type: GrantFiled: May 15, 2009Date of Patent: July 21, 2015Assignee: KIT MASTERS INC.Inventors: Craig M. Swanson, Thomas M. Jagger, George S. Pieper

Patent number: 8863929Abstract: Some embodiments of a clutch system may drive an output portion to rotate at a first rotational speed when the clutch surfaces are engaged and to rotate at a second rotational speed when the clutch surfaces are shifted to a disengaged position. The viscous two-speed clutch system may employ a viscous drive system that causes the output portion to rotate even when the clutch surfaces are disengaged. In such circumstances, the cooling fan can be driven to rotate at a first rotation speed due to interconnection with a drive source and to rotate at a second rotational speed even when the clutch surfaces are disengaged. Thus, the clutch system facilitates the flow of cooling air both when the vehicle cooling system activates the fan (e.g. by causing the clutch surface to engage) and when the vehicle cooling system deactivates the fan (e.g. by causing the clutch surfaces to disengage).Type: GrantFiled: December 22, 2011Date of Patent: October 21, 2014Assignee: Kit MastersInventors: Paul Roczniak, Thomas M. Jagger, Craig M. Swanson
