  • Drive coupling and clutches
    Patent number: 4189038
    Abstract: Corresponding sets of radially distributed helical surfaces in a cone clutch axially urge movable cone members selectively into engagement with either of two mating cone members thereby enabling a clutch output member to be driven in either rotary direction.
    Type: Grant
    Filed: July 18, 1977
    Date of Patent: February 19, 1980
    Assignee: Chrysler Corporation
    Inventor: John W. Hurst
  • Drive couplings and clutches
    Patent number: 4150590
    Abstract: Differential gear sets and planetary gear sets in combination with sets of corresponding radially distributed helical surfaces in drive couplings such as cone clutches. The helical surfaces allow axial movement of the cone members of a clutch selectively into engagement with either of two mating cone members thereby enabling an output member to be selectively driven bidirectionally.
    Type: Grant
    Filed: July 29, 1977
    Date of Patent: April 24, 1979
    Assignee: Chrysler Corporation
    Inventor: John W. Hurst
  • Bidirectional drive coupling
    Patent number: 4051934
    Abstract: Corresponding sets of radially distributed helical surfaces in a drive coupling for axially urging either of two female cone members into positive engagement with a male cone member and providing a selectively bidirectional rotary output.
    Type: Grant
    Filed: April 23, 1976
    Date of Patent: October 4, 1977
    Assignee: Chrysler Corporation
    Inventor: John W. Hurst
  • Clutch shifting mechanism
    Patent number: 4049102
    Abstract: The invention relates to shift control mechanisms for clutches in which a cam and follower are used to control shifting of the clutch.
    Type: Grant
    Filed: July 19, 1976
    Date of Patent: September 20, 1977
    Assignee: Chrysler Corporation
    Inventor: John W. Hurst
  • Drive coupling and clutches
    Patent number: 4022308
    Abstract: Corresponding sets of radially distributed helical surfaces in a cone clutch axially urge movable cone members selectively into engagement with either of two mating cone members thereby enabling a clutch output member or members to be driven in either rotary direction.
    Type: Grant
    Filed: April 23, 1976
    Date of Patent: May 10, 1977
    Assignee: Chrysler Corporation
    Inventor: John W. Hurst
  • Clutch
    Patent number: 3977503
    Abstract: Corresponding sets of radially distributed helical surfaces in a cone clutch for axially urging either of two female cone members into more positive engagement with a male cone member and for driving a clutch output member or members.
    Type: Grant
    Filed: July 23, 1975
    Date of Patent: August 31, 1976
    Assignee: Chrysler Corporation
    Inventor: John W. Hurst
  • Kick-up/steering camming feature for inboard-outboard marine drive
    Patent number: 3957011
    Abstract: A camming surface on the inner peripheral edge of the transom opening limits steering angle of the I/O power leg as it is tilted up. Full steering is permitted at lower tilt positions and limited steering is permitted at raised positions. This arrangement makes the unit more adaptable to various size transoms, affords a neater appearance and reduces weight and cost.
