Abstract: A method and apparatus for forming wheel rims using a wheel rim blank having a well center region with a diameter equal to the diameter of the well center of the finished wheel rim. Two female die halves form a cavity to confine the wheel rim blank and two male dies cooperate with the female die halves to flare the bead seat regions of the wheel rim blank. The bead seat regions of the wheel rim blank are subsequently contoured to final dimensions between two additional female die halves by two additional male dies.

Abstract: An adjustable handlebar system includes handlebar means to provide handle grips for a vehicle that are adapted for movement with respect to the vehicle. At least a pair of unidirectional clutch means control movement of the handlebar means. Each clutch means is engaged with the handlebar means and is connected to a part of the vehicle. The handlebar means and clutch means are interconnected to prevent movement in two opposite directions and to hold the handle grips immovable in the absence of operation of the clutches. One clutch means is operated to permit infinitely variable movement of the handle grips in one direction and the other clutch means is operated to permit infinitely variable movement of the handlebar means in the other direction.

Abstract: A combination speed control and transmission forward-reverse control for a lawn tractor, or the like, having an engine including a drive shaft and output pulley, a transmission including a driven input shaft and pulley, and a belt-tensioning, or other similar type clutch. The control includes an actuating lever mounted on the tractor chassis, and control cables extending between the actuating lever and the clutch, and between the actuating lever and the transmission forward-reverse shift linkage. Movement of the actuating lever in the forward direction shifts the transmission linkage to the forward position and releases the clutch to engage the driving and driven pulleys with one another. Further forward motion of the actuating lever causes a greater coupling of the driving and driven pulleys to cause the lawn tractor to move forward faster. Returning of the actuating lever to a neutral position disengages the clutch and moves the transmission shift linkage to neutral.
