This disclosure relates to needle guards for rotary loop takers in sewing machines and has for its purpose prevention of interference between the needle and the loop seizing beak of the rotary loop taker during the sewing operation. A needle guard is provided which is substantially annular and open ended and is resiliently supported within the body of the loop taker. One leg of the needle guard is disposed in the region of the loop seizing beak of the loop taker and in the region of the needle path so that the needle if proceeding toward the loop seizing beak upon penetration of the fabric, will be deflected away from the loop seizing beak and toward the center of the loop taker body. An adjustable anchoring means is provided for the one leg of the needle guard for adjusting the relative position of said one leg relative to the loop seizing beak. The needle guard itself is formed from a resilient wire such that it may be readily snapped in and out of the loop taker body for easy replacement if warranted by unusual wear conditions.
A needle guard for a sewing machine loop taker, said loop taker including a cup-shaped body formed by a bottom wall, a vertical side wall extending from said bottom wall and an annular wall extending laterally from the periphery of said side wall, a loop seizing beak formed in said annular wall, and a substantially annular open-ended needle guard disposed within said cup-shaped side body and having one leg thereof disposed adjacent said loop seizing beak for deflecting a needle away from said loop seizing beak and toward the center of the loop taker body.
