A test model was flown with a Wankel engine with a large three bladed 100 inch diameter propeller with a belt driven gear reduction unit and a fuselage-length exhaust canted upward.

At low RPM a centrifugal crankshaft driven gear opens the valve into a small chamber and increases the volume of the exhaust by allowing the exhaust gases to flow through the chamber.

A gear motor ( external gear ) consists of two gears, the driven gear ( attached to the output shaft by way of a key, etc . ) and the idler gear.

Swing it ( the idler gear ) out of the way, then bring the other long arc lever ( controlling the driven gear ) to the opposite extreme, then swing the idler gear back-to re-engage.

He also has the honor of being history's first " vaporware " vendor, in that he announced plans for a steam-driven gear-worked data-processing machine _ a " difference engine, " as he called it _ but never actually completed a working model.

It exists because there is always some gap between the trailing face of the driving tooth and the leading face of the tooth behind it on the driven gear, and that gap must be closed before force can be transferred in the new direction.

In 1962, Chrysler introduced a starter incorporating a geartrain between the motor and the drive shaft . The motor shaft included integrally cut gear teeth forming a pinion that meshes with a larger adjacent driven gear to provide a gear reduction ratio of 3.75 : 1.

Each of the forward gears on the countershaft is permanently meshed with a corresponding gear on the output shaft . However, these driven gears are not rigidly attached to the output shaft : although the shaft runs through them, they spin independently of it, which is made possible by Reverse.

In addition to the original consignment of parts from the estate of Robert Sprague, a private collector, the parts inventory on the block continues to expand; there are now 13 engines, including two recent additions : a Mason engine dating from around 1901 and a Stanley engine, serial F290, complete with driven gear and spider gears.
