Abstract
The abutment mechanism provides a resilient damping stop to dampen the initial stopping motion of a moveable drive member of a weft thread return mechanism or weft thread mixer changer as well as a rigid stop to stop movement of the drive member. The mechanism employs a spring biased bolt as an initial stop member. The housing for the bolt can be used as the final stop member or a rigid stop can be positioned within the housing to arrest motion of the bolt. A pin laterally offset from the bolt can also be used as the rigid stop.

In a weaving machine having a frame, a main drive, a sub-assembly including a movable member for driving off said main drive and a transmission means for imparting a controlled limited movement from said main drive to said movable member to move said member in a predetermined path;
- a tubular housing, a sleeve mounted on and about said housing to fix said housing to said frame, a resilient damping stop disposed in said path, said stop including a spring biased bolt slidably guided in and projecting from said housing member to initially dampen movement of said member in said path and a fixedly mounted rigid stop disposed in said path to stop movement to said member.
An abutment mechanism for a movable drive member of a weaving machine, said mechanism comprising
- a tubular housing having a bore and a counterbore extending therethrough in coaxial relation;
- a sleeve threadably mounted about and on said housing;
- a bolt slidably mounted in and projecting from said bore, said bolt having a shoulder disposed in said counterbore;
- a spring in said counterbore in abutment with said shoulder to bias said bolt out of said bore;
- and
- a stud secured in said housing in abutment with said spring on a side opposite said shoulder.
