No jerks-no rattles - when you throw in the clutch How the new flexible fabric universal joint absorbs the shocks l that wear out your car

A RAPIDLY spinning flywheel suddenly locked XX. with a motionless rear axle—that’s what happens when you start your car. A ton or more of dead weight must be moved the instant you throw in the clutch. The tremendous power from the engine is hurled along the drive shaft Metal universal joints transmit with no cushioning whatever the full impact of this terrific force. No matter how carefully you engage the clutch, a violent blow racks the transmission and the whole

rear axle assembly. As metal joints become worn the strain is intensified. Cushioning the shocks in the drive shaft ' There is now a way to absorb these blowa Constructed of flexible fabric discs, the Thermoid-Hardy Universal Joint effectively cushions the shocks that rack your car. You feel no jerks, no rattles when you throw in the clutch. With the Thermoid-

fit buikUng up th* flexible Ubrtc disc* the severel layers of fabric are put together so that the strands in each piece run in a different direction. This patented fanwiee construction provides the greatest tensile strength. In a laboratory test made recently at Purdue University the drive shaft itself was twisted at a toted stress of 2IJOO inch pounds without injury to the universal Joint.

Hardy Universal Joint your car starts smoothly— runs quietly with the minimum of jar and vibration. Fanwise construction for strength Enormous strength is given the Thermoid-Hardy Universal Joints by the patented fanwise construction of the fabric discs illustrated below. By no other construction can uniform strength and elasticity be obtained. Having no metal-to-metal wearing surfaces the Thermoid-Hardy Joint cannot wear loose. It requires no lubrication—no constant attention. Adopted by leading manufacturers Over fifty manufacturers have adopted the Thermoid-Hardy Universal Joint as standard equipment It has stood severe endurance tests—in many cars running 60,000 miles without replacement or adjustment. . • When you ride in a car equipped with Thermoid-Hardy Universal Joints, notice the absence of backlash, jerks, and rattles that are so common with metal joints. Observe how smoothly the car starts—how much more quietly it runs—even over rough roads. Send for our new book, “Universal Joints—Their Use and Misuse. ,, It will give you in detail the construction of the Thermoid-Hardy Joint, records of performance, opinions of leading engineers and manufacturers who have adopted it.
