Racking mechanism for bobbin machine

A bobbin-racking mechanism for a jacquard machine, said mechanism comprising:

• a support;
• a drive gear rotatable on said support about a drive axis;
• a transmission member rotatable on said support independent of said drive gear about said drive axis;
• an output member connectable to a bobbin and rotatable on said support independent of said drive gear and transmission member about said drive axis;
• an output gear fixed to said output member and spaced from said drive gear;
• a transmission gear rotatable on said transmission member about a transmission axis transverse to said drive axis and meshing simultaneously with said drive gear and said output gear, whereby on rotation of said transmission member said transmission gear orbits about said drive axis;
• and
• operator means engageable with said members and displaceable between a stopping position preventing rotation of said output member and permitting rotation of said transmission member and a racking position permitting rotation of said output member and preventing rotation of said transmission member,
• said operator means including an operator shaft pivotal about an operator axis generally parallel to said drive axis and having an output arm engageable with said output member and fixed on said operator shaft and a transmission arm engageable with said transmission member and fixed on said operator shaft;
• and further comprising means including a cam on said drive gear and a reset arm on said operator shaft for displacing said operator means from said racking into said stopping position.
