摘要： A threader for a mounted sewing machine needle having an eye adjacent the pointed lower end thereof includes a base plate adapted to be received beneath the foot of the machine, and a housing providing a positioning recess for aligning the needle threader with the sewing machine needle eye. The housing supports a pair of reciprocable thread pusher members at right angles to one another, and when the device is aligned with the needle eye, the first pusher member is displaceable from a retracted to an extended position to push a strand of thread through the needle eye from one side thereof to the other. When the first pusher member is returned to the retracted position, the second thread pusher member is displaceable from a retracted to an extended position to engage a loop of thread on the other side of the needle eye and to displace the thread laterally of the needle to a position where it can be easily grasped by the user's fingers.

摘要： A manually operable needle threading device comprises a housing having a recess for positioning the eye of a needle to be threaded in alignment with the path of a displaceable thread pusher member in the housing, whereby displacement of the pusher member from a retracted to an extended position pushes a portion of a thread between the needle and pusher member through the needle eye. The pusher member displaces the portion of thread between gripping fingers on the housing which hold the thread portion upon displacement of the pusher member from the extended to the retracted position. The portion of thread remains attached to the threading device upon separation of the needle therefrom until a loose end of the thread passes through the needle eye to complete the threading operation, after which the thread portion is released from the threading device. In one embodiment the housing is of pistol-like configuration facilitating handling and operation of the threading device.

摘要： An improved manually operable needle threading device is provided of the character including a housing having an upwardly extending tubular needle receiving support and a displaceable needle threader member in the housing for displacing a thread through openings in the needle support and the eye of a needle therein. The improvements include a slot extending upwardly through the needle support from one of the openings therein to facilitate removal of the threaded needle when one end of the thread is fixed against movement, and an improved actuating arrangement for displacing the needle threader member relative to the needle support.
