A company called the Gearless Transmission Co. produced a direct drive friction transmission prior to 1906 in Glen Falls, NY. After 1906 the company moved to a larger factory in Rochester, NY.
This transmission could be adapted to any American Automobile in the early 1900s and was "The Only Direct Drive Friction Transmission". The Gearless Transmission did away entirely with the use of gears and provided infinitely variable frictional gearing or an unlimited number of speeds, both forward or reverse.
The general scheme is shown below in three images. In Figure 1 - A is the engine flywheel, B is a clutch drum, C is the driven disc mounted on the propeller shaft D. C and D are moved forward and backward for
varying speeds by rod C.
The Gearless Transmission was built in two sizes. One for light cars and another heavy cars. The Gearless Transmission claimed that their transmission put less strain on the runing gear of a can than any other transmission.
Figure No.1 Gearless Transmission
Intermediate discs "d" left and "d" right are supported in frame E which also has a bearing for propeller shaft D. Both Intermediate discs are drawn toward the shaft and into engagement with disc C and at the same time into engagement with the flywheel A.
This action impels the driven disc C at a speed corresponding to the distance from the axis of the intermediate discs
"d". The motion of discs "d" is affected by both arms F.
Arms F are connected together to a pedal by links "f". When the driven disc C reaches the position shown the swing arm of the clutch B is engaged by a cone G carried by the disc C, engaging the clutch and positively connecting the motor to the propeller shaft D.
