摘要： A drive mechanism for a pair of loop takers each cooperating with a separate needle of a two-needle sewing machine in which a single timing belt is used to drive both loop takers. An arrangement is disclosed which permits the spacing between the loop takers to be changed without disturbing the driving connections, and which provides for regulation of a single one of the connections in the loop taker drive with respect to the needle drive in order to reestablish proper timing of both of the loop takers with respect to the respective needle reciprocation when the spacing between loop takers is changed.

摘要： A lubricant pump is provided comprising a plain cylindrical driveshaft on which is arranged a shaft collar formed with a plain cylindrical bore embracing the driveshaft. A spring is attached to the collar and extends to an anchor point on the sewing machine frame to bias the collar against the driveshaft. The spring displaces the collar arranging the collar bore eccentrically with respect to the driveshaft. An oil inlet port is formed in the collar leading to a point on the collar bore which is urged away from the driveshaft by the spring, and a lubricant outlet bore is formed in the bushing leading to the point on the bushing bore which is closest to the surface of the driveshaft in response to the pressure of the spring.

摘要： A thread pull-off and wiping mechanism for sewing machines in which thread-engaging pull-off and thread wiping elements are reciprocated by a spring-returned linkage that may be detained in an inoperative position by a latch device, which, when released permits the linkage to assume an operative relation to a drive element operating in timed relation with the sewing machine thread take-up mechanism.
