Patent number: 11052715Abstract: The present disclosure includes independent suspension systems or members, as well as wheeled skid steer loaders or other power machines including the same, that couple each wheel to a machine frame using a four-bar linkage, with the four bars including the frame of the machine, an upper control arm, a lower control arm, and a wheel carrier link. Each control arm is pivotally attached to both the machine frame and one end of the wheel carrier link. The four pivots between the control arms and the wheel carrier link are configured to all be contained within cylinder defined by the outer diameter of the wheel rim, allowing for a compact structure with the wheel carrier link and at least part of the control arms being positioned within this volume when the loader is in a resting position.Type: GrantFiled: November 2, 2018Date of Patent: July 6, 2021Assignee: CLARK EQUIPMENT COMPANYInventors: Thomas J.

Patent number: 7691223Abstract: An apparatus for making SMC comprising a conveyor belt assembly having a feed end and a transfer end. The conveyor belt assembly including a belt having an outer surface and an inner surface. A cutting support structure disposed between the feed end and the transfer end, and in contact with the inner surface. A cutting wheel having a perimeter surface and disposed adjacent to the cutting support structure. A feed tension member proximate the outer surface and disposed between the feed end and the cutting wheel. The feed tension member positions the fiber rovings onto the outer surface to be cut by the cutting wheel. The feed tension member, cutting wheel and belt cooperate to feed the fiber rovings at a feed rate, cut the fiber rovings into a plurality of parallel discontinuous fibers, and convey the fibers at substantially the same rate as the feed rate.Type: GrantFiled: January 25, 2007Date of Patent: April 6, 2010Assignee: Ford Global Technologies, LLCInventors: Jeffrey Dahl, Glen L. Smith, Raymond Silva, Carl Johnson

Patent number: 6572179Abstract: A wheeled work machine has a cab that is assembled with side panel assemblies that are each formed from two mating die formed side panel sections so that smoothly curved shapes, and recessed cross sections can be made. When the two panel sections are rigidly joined together, they form strong, bend and torsion resistant box sections for structural members around an operator access opening, as well as around an accessory opening. The inner one of the die formed panel sections includes flanges that extend inwardly toward the center portions of the cab for supporting cross panels such as seat supports, a roof, and a dash board assembly. The side panels and cross members are spot welded together to form a quickly made, smooth appearing, and very strong operator cab.Type: GrantFiled: October 12, 2001Date of Patent: June 3, 2003Assignee: Clark Equipment CompanyInventors: Jeffrey A.
