Patent number: 7229140Abstract: A pretensioned spring track tensioning system provides a two stage loading of a tension roller on the interior of a vehicle drive track. The two stage loading first loads the track under a lower tension load for normal operation, but when the track is highly loaded, such as when digging, or when debris is forced between the track member and its drive sprocket or guide rollers, the compression of the lighter spring will be stopped mechanically and a second heavier compression spring will provide the tension loading. The additional spring tension under unusual conditions prevents detracking of the track and buckling of the track. A lighter tension load during normal operations reduces the loads on bearings, particularly in relation to a drive motor. The tensioning system has particular adaptability to “high” drive type tracks which have a drive sprocket elevated above the tension roller.Type: GrantFiled: April 1, 2004Date of Patent: June 12, 2007Assignee: Clark Equipment CompanyInventors: James H.

Patent number: 6902016Abstract: A small or mini loader is operated by a platform standing on the ground or other surface supporting the loader, and at the rear of the machine. Hydraulic control levers operate drives on opposite sides of the machine, and the control levers are pulled rearwardly from a stopped position to effect the rearward drive. A pivoting panel is mounted on the rear of the frame and has a wall portion that protrudes outwardly from the rear of the machine. When the lower end of the pivoting panel engages an obstruction or other item that provides a force tending to move the lower end of the panel forwardly relative to the frame, an actuator arm will move to cause control levers that are in a rearward drive position to be moved to the stopped position.Type: GrantFiled: February 8, 2002Date of Patent: June 7, 2005Assignee: Clark Equipment CompanyInventors: Mark F. Bares, James H. Page

Patent number: 6698114Abstract: A lift arm assembly for a small or “mini” loader is pivotally mounted onto a self propelled frame for movement between a raised and a lowered position. In the raised position, a support strut is provided that fits over an extended rod of the lift arm operating cylinder and will prevent the lift arm assembly from lowering. The support strut is stored in a front tubular cross member of the lift arm assembly. Additionally, the front cross member supports an upright strut that acts as a back stop for material in a bucket, by projecting upwardly beyond the bucket top so that if an object in the bucket tends to roll rearwardly, if the bucket is not leveled, it will be intercepted by the upwardly projecting portion of the back stop and deflected laterally.Type: GrantFiled: January 11, 2002Date of Patent: March 2, 2004Assignee: Clark Equipment CompanyInventors: Mark F.

Patent number: 6662556Abstract: A small self-propelled loader has hydraulic drive motors and at least one work cylinder, and has a hydraulic system that efficiently utilizes the available horse power from an internal combustion engine on the loader. The engine drives a tandem pump and the flows from two sections of the tandem pump pass through a first diverter valve that permits using the flow from each of the pump sections to drive a respective one of the drive motors. The return or drain flow from valves controlling the drive motors is connected to a second diverter valve to selectively direct the drain flow from the drive motors for operating remote work cylinders. Alternately, the first diverter valve directs the output from one pump section to the work cylinders, so that when the loader is standing still or moving very slowly, the work cylinder has adequate flow, and flow from the other pump section is split to power the drive motors.Type: GrantFiled: February 25, 2002Date of Patent: December 16, 2003Assignee: Clark Equipment CompanyInventors: Mark F.
