Abstract
An actuator assembly comprising at least one prime mover, a shaft having a first end and a second end, the shaft being operatively connected to the prime mover for reciprocal movement, a frame, the shaft being reciprocably movable in the frame, and linkage attached to the frame and operatively connected to the shaft, the linkage being movable between a first position and a second position in response to reciprocal movement of the shaft and a selectively engageable stroke-limiting assembly operatively connected to the shaft for controlling movement of the shaft, either by preventing any movement of the shaft or limiting its stroke a predetermined amount.
Claims66
An actuator assembly comprising:
- at least one prime mover;
- a shaft having a first end and a second end, said shaft being operably connected to said prime mover for longitudinal, reciprocal movement;
- a frame, said shaft being reciprocably movable in said frame;
- a linkage attached to said frame and operably connected to said shaft, said linkage being movable between a first position and a second position in response to reciprocal movement of said shaft;
- a selectively engageable locking assembly operatively connected to said shaft, said locking assembly preventing movement of said shaft when said shaft is in a predetermined position,
- and an adjustment assembly operatively connected to said shaft, said adjustment assembly being selectively adjustable to determine said predetermined position.
3 more elements
An actuator assembly comprising;
- at least one prime mover;
- a shaft having a first section and a second section, such shaft being operably connected to said prime mover for longitudinal, reciprocal movement between first and second, axially spaced locations;
- a frame, said shaft being reciprocally movable in said frame;
- a linkage attached to said frame and operably connected to said shaft, said linkage being movable between a first position and a second position in response to reciprocal movement of said shaft;
- a stop selectively engageable with said second portion of said shaft, said stop preventing movement of said shaft to said second location when said stop engages said second section of said shaft;
- and
- a blocking assembly operatively connected to said stop, said blocking assembly being selectively actuatable to prevent engagement between said second section of said first shaft and said stop.

An actuator assembly comprising:
- at least one prime mover;
- a shaft having a first section and a second section, said shaft being operably connected to said prime mover for longitudinal, reciprocal movement;
- a frame, said shaft being reciprocally moveable in said frame;
- a linkage attached to said frame and operably connected to said shaft, said linkage being moveable between a first position and a second position in response to said reciprocal movement of said shaft;
- a selectively engageable locking assembly operatively connected to said shaft, said locking assembly being operable to prevent movement of said shaft when said shaft is in a predetermined position;
- a guide having a first and a second end, said shaft being slidably mounted in said guide, said first end of said guide being connected to said frame;
- and
- a tubular housing having a first end and a second end, said first end of said housing being attached to said second end of said guide and being longitudinally adjustable with respect to said guide, said locking assembly being operable to selectively interconnect said housing and said shaft.
5 more elements
An actuator assembly comprising:
- first and second prime movers;
- a frame interconnecting said first and second prime movers;
- a shaft having first and second shaft sections, said first shaft section being connected to said first prime mover, said second shaft section being connected to said second prime mover, said shaft being reciprocally movable in said frame;
- a linkage attached to said frame and operably connected to said shaft, said linkage being movable between a first position and a second position in response to said reciprocal movement of said shaft;
- a first, selectively engageable locking assembly operatively connected to said first shaft section, said first locking assembly preventing movement of said shaft when said shaft is in a first predetermined position;
- a first guide having a first end and a second end, said first end of said first guide being connected to said first prime mover distal said frame, said first shaft section being slidably mounted in said first guide;
- a first tubular housing having a first end and a second end, said first end of said first tubular housing being attached to said second end of said first guide and being longitudinally adjustable with respect to said first guide, said first locking assembly being operable to selectively interconnect said first housing and said first shaft section;
- a second selectively engageable locking assembly operatively connected to said second shaft section, said second locking assembly preventing movement of said shaft when said shaft is in a second predetermined position;
- a second guide having a first end and a second end, said first end of said second guide being connected to said second prime mover distal said frame, said second shaft section being slidably mounted in said second guide;
- and
- a second tubular housing having a first end and second end, said first end of said second tubular housing being attached to said second end of said second guide and being longitudinally adjustable with respect to said second guide, said second locking assembly being operable to selectively interconnect said second housing and said second shaft section.
