Abstract
An apparatus for reversing and racing a card in a dobby machine by using a planetary gear mechanism for reversing a card cylinder by a specified angle and operating a card handle fixed on the shaft, thus avoiding damage to the machinery even when operational errors occur.
Claims12
An apparatus for reversing and racing a card cylinder in a dobby machine comprising a shaft adapted to be drivingly connected to the card cylinder;
- a first gear rotatably mounted on said shaft;
- a second gear secured to and axially spaced from said first gear;
- an annular housing positioned about said shaft having an internal gear extending circumferentailly therewithin;
- a planetary gear means including a disc element rotatably mounted about said shaft, a pin carried by said disc element adjacent the periphery thereof, and a planetary gear mounted on said pin and rotatable relative to said disc element;
- a card handle mounted on said shaft at the longitudinal end thereof remote from the operative connection of said shaft with the card cylinder to be axially movable therealong the thereby selectively rotatable therewith;
- and an operating handle connected operatively to said planetary gear and operable to be rotated to thereby effect reversing of the card cylinder.

- a second gear secured to and axially spaced from said first gear;
- an annular housing disposed about said shaft having a circumferentially extending internal gear;
- a planetary gear means comprising a disc element rotatably carried by said second gear and a planetary gear rotatably carried by said disc element adjacent the periphery thereof and operatively disposed between said internal gear and said second gear;
- a card handle mounted on one longitudinal end of said shaft axially movable thereon for selective operative engagement or disengagement with said housing;
- and an operating handle connected to said disc element and operable to be rotated to rotate said disc element;
- whereby racing and reversing of said card cylinder is effected by operation respectively of said card handle and said operating handle.
