ABSTRACT:
This invention provides novel transmission means for interconnecting a rotary output shaft of drive means to a rotary input shaft of means to be driven by the drive means. Basically, the novel transmission means of the present invention comprises gear means mounted on base means for rotary movement relative thereto, with those gear means comprising first, second, third and fourth gears and each of those four gears including a hollow, fluid-receiving, radially inner hub portion that is rotatably mounted to the base means and a radially outer portion that is divided into plural segments, each having a radially outer end that is provided with teeth and a radially inner end comprising an arm mounted within the hollow hub portion for slidable movement relative thereto both towards and away from the radial center of the hub portion. The hub portion of the first gear is connectable to the output shaft, the hub portion of the fourth gear is connectable to the input shaft, and the hub portions of the second and third gears are connected to one another. The novel transmission means further includes first endless chain means engageable with the radially outer portions of the first and second gears to interconnect the same and second endless chain means engageable with the radially outer portions of the third and fourth gears to interconnect the same, as well as means for selectively supplying and removing pressurized fluid to and from the hollow hub portions of the gears for selectively slidably moving the segments of the gears radially outwardly and inwardly with respect to their hub portions.
