Patent number: 9587646Abstract: A system, in certain embodiments, includes a centrifugal compressor diffuser including a flow path having a first surface and a second surface defining opposite axial sides of the flow path. The centrifugal compressor diffuser also includes multiple vanes extending from the first surface to the second surface of the flow path. A first profile of each vane varies along an axial direction. The centrifugal compressor diffuser further includes multiple vanelets extending from the first surface toward the second surface in the axial direction. A first axial extent of each vanelet is less than a second axial extent of the flow path. In addition, a second profile of each vanelet varies along the axial direction and/or the vanelets form a non-periodic pattern around a circumference of the flow path.Type: GrantFiled: August 23, 2013Date of Patent: March 7, 2017Assignee: Ingersoll-Rand CompanyInventors: Chester V.

Patent number: 7287769Abstract: An engine and rear axle are mounted on a drive train sub-frame of a utility vehicle, with two generally parallel plates spaced from each other on the first end of the drive train sub-frame. A cross bolt extends laterally between the two plates and through an opening in a retainer attached to the main frame of the utility vehicle. The retainer opening has a height and width larger than the diameter of the cross bolt.Type: GrantFiled: June 29, 2004Date of Patent: October 30, 2007Assignee: Deere & CompanyInventors: Daniel Bruce Thiemke, Brian James Hitt

Patent number: 7204397Abstract: A cargo container attachment for a small vehicle such as a lawn tractor is provided. The container is removably attached to the rear of the vehicle and includes a cargo box storage space with a pivotally mounted swingable tailgate. The container is designed to be used in conjunction with a lawn tractor to perform landscaping and structural maintenance tasks. Materials such as mulch, soil and plantings as well as maintenance materials can be transported in the cargo space. The tailgate can be moved between a first position where it serves to enclose the storage space and a second position where its serves as a workbench surface. Tool receiving recesses are provided in the sidewall edges of the composite container for transporting small tools such as trimmers, shovels, shears and/or rakes.Type: GrantFiled: April 28, 2003Date of Patent: April 17, 2007Assignee: Deere & CompanyInventors: Matthew Elmer Powell, Brian James Hitt, Jeffrey Robert Braun

Patent number: 6910681Abstract: A tubular axle housing is provided with pairs of tabs that protrude or extend from the axle to a height or length sufficient to prevent the intermediate section of a U-bolt from sliding over the tab. The tabs also help locate and guide the U-bolt between the tabs during the assembly of a leaf spring to the axle housing. The tabs provide a positive locking feature for the U-bolts during service of a vehicle, to prevent the U-bolts from moving laterally along the axis of the axle tube. As a result, the joint between the leaf spring and axle housing is more secure.Type: GrantFiled: February 12, 2004Date of Patent: June 28, 2005Assignee: Deere & CompanyInventors: Brian James Hitt, Michael Bedis, Rocky Hudson Page

Patent number: 6679037Abstract: A device for suspending a mower cutting deck that includes a retention member connected with the frame of a vehicle. The retention member receives a linkage bridging the cutting deck and the frame. To receive this linkage, the retention member includes a channel having a top end through which the linkage is inserted and a bottom end in which the linkage seats when the deck and the frame are connected. A throat portion is provided between the top and bottom ends. The throat portion is laterally offset from the ends and provides an abutment which opposes inadvertent vertical movement of the linkage beyond the bottom end to substantially prevent it from moving out of the retention member. With this opposition, the deck can maintain its attachment with the frame of the vehicle while using a minimal amount of hardware.Type: GrantFiled: September 20, 2002Date of Patent: January 20, 2004Assignee: Deere & CompanyInventors: Brian James Hitt, Brian David Seegert
