Abstract
Abstract A thrust mechanism on a shaft structure comprises a member slidably mounted on the structure for movement longitudinally thereof, stop means positioned on the structure at the terminus of such movement, and first and second thrust members. The first thrust member is slidably mounted on the structure for movement longitudinally thereof into bearing contact with the slidable member. Means are provided for slidably mounting the first thrust member against turning movement thereof relative to the structure. Second stop means are provided on the shaft structure, together with means for mounting the second thrust member against the second stop means for turning movement thereof relative to the shaft structure. Means are provided for securing the second thrust member to the structure against further turning movement thereof following a predetermined limited angular displacement of the second thrust member, together with means on at least one of the thrust members and engageable with the other of the thrust members for urging the first thrust member and the slidable member against the first stop means and for urging the second thrust member against the second stop means.
